On the day of the college entrance examination, I was suddenly confined in a pitch-black secret room by God.

My heart raced as fear gripped me. I stumbled and fell, and everyone in the world’s ankle swelled up. It was then I realized – if I died, humanity would be destroyed along with me.

My only hope for survival was a small 1 cm diameter hole in the wall, connecting me to the billions of lives outside the secret room that depended on mine.

Everyone thought I would live a miserable life. But I managed to create a three-story villa with my bare hands, not only raising fish, shrimp, and birds but also growing flowers, grass, and grains.

1.

I was confined in a pitch-black secret room. I frantically pounded the ground, my hands stinging with pain. The darkness was suffocating, pressing in on me from all sides. It felt as if unseen monsters with sharp claws and teeth were drawing closer, ready to devour me. Desperation clawed at my mind as I mustered what little courage I had left and focused on the faint light from the small hole. This was not a dream; it was a nightmare I couldn’t wake up from.

Time went back ten minutes.

in the examination room, I was grappling with a math problem. the teacher who set the questions had a very tricky perspective, and I was at a loss, my heart racing with anxiety. Suddenly, everything around me came to a halt. The surroundings fell silent; even the sparrows outside the window that had been chirping annoyingly quieted down. My brain could still think, but I couldn’t control my body, completely unable to move. What was going on?

“Hello, residents of Earth, I am your God.” A solemn yet ethereal voice seemed to come from a very distant place or appeared directly in my mind out of thin air.

“I am giving you a test. If you succeed, you will gain another 4,000 years of civilization development time.” This statement caught my attention. Why 4,000 years? Why say “again”?

“But if you fail the test, everything you rely on will disappear. The Earth will be destroyed and restarted. I will select one person from among you and confine them in a pitch-black secret room I created a room you absolutely cannot break. Rest assured; I will leave a 1 cm diameter hole in the wall of the secret room.

“This secret room cannot be destroyed, and the person inside cannot leave. There are no supplies inside. If they can survive until the age of 70, they will be freed and granted eternal life.

“Your challenge is to find every possible way to keep the person inside alive. Remember, if the person in the secret room is alive, you live; if the person in the secret room dies, you all die. Now, the challenge begins.”

This sudden string of voices left me baffled. Who was playing such a prank? Just as I was about to continue my mental rant, the surroundings suddenly spun. The light gradually disappeared, and the other people in the examination room were nowhere to be seen. “Hey, is anyone there? Invigilator, I can’t see anything.” I said softly, afraid of being disqualified from the exam.

I finally regained control of my body, but I couldn’t see anything, not even my hand waving in front of my eyes. Was it because I studied too hard last night and went blind? “No, your eyes are fine, and you didn’t study hard last night. You were just chosen by me. Try to survive, young man.” It was that voice again.

Could I have been kidnapped? No, how could this guy hear my inner thoughts? “Because I am God,” the voice said, then fell silent. No matter how much I called, cursed, or pleaded, there was no response. Only the dark space reminded me that this was all true.

2.

I approached the hole. “Hey! Is anyone there?” I got as close as possible to the hole in the wall and shouted outside with all my might. Fortunately, the hole was at the height of my mouth when I stood upright, so I didn’t have to strain to reach it. But after shouting several times, there was no response. I lowered my head slightly and looked out through the hole, trying to determine where I was. I saw a row of horizontal bars, a basketball hoop, a wire fence, and further away, a green belt. I should be at the school playground. It seemed that I had been transported from the examination room to the school playground by the so-called “God.”

The playground was empty. In the other direction was the teaching building. The students were probably still inside, but the exam should be ending soon. Oh no, I still had several questions left unanswered! Sure enough, the bell rang after a while. I shouted outside again. The students who finished the exam walked towards my direction.

“Look, when did such a big house appear on the playground?”

“I don’t know, maybe it was built temporarily. It looks quite mysterious.”

“By the way, I heard some strange sounds during the exam. I wonder who was playing a prank?”

“You heard it too? I thought it was my imagination!”

“And it was so weird. I was doing my questions, and my hand suddenly hurt like it had been hit.”

“Ah? Your hand hurt too?”

“Me too, so strange!”

I didn’t have time to think about why their hands hurt too. I took the opportunity to shout, “Help me, I’m trapped in here!” They chatted and walked closer but didn’t seem to hear me. In the darkness, I hurriedly ran towards their direction, banging on the wall as I ran. But I tripped over something and fell, hitting my ankle against the wall, which soon swelled up. The pain left me speechless. I even heard people outside crying out in pain one after another, as if they were under attack. What was going on? Was there danger outside too?

After a while, I found a pen on the ground, probably something that had fallen earlier. In a moment of inspiration, I tore a long, thin strip from my pants and tied it around the pen. Then I threaded the pen through the hole, hanging it outside the wall. I pulled the string, making the pen hit the outside of the wall, creating a clatter that finally caught their attention.

“Who’s in there?” a girl asked nervously, peering into the hole, her brow furrowed. Unfortunately, there was hardly any light where I was, and she probably could only see a shadow. “My name is Ben, I’m also a student taking the exam. I’m trapped in this house, please help me.” I replied.

“How did you get in there?” another boy asked. I anxiously said, “I don’t know either. I was just doing my exam when suddenly I was locked in here.”

“Damn! That voice might be real,” the boy voiced what I was thinking. “I think it might be. Otherwise, why would all our hands suddenly hurt?”

“And our ankles. We were walking fine, and then our ankles seemed to twist all at once!” They discussed excitedly, their voices getting louder. I had to remind them loudly that someone was still trapped inside.

“Where’s the door?” they tried to find it for a while but couldn’t. I grew more anxious: “I don’t know either, it’s pitch-dark inside, I can’t see anything.” They circled the house again and then told me, “We looked everywhere, but we couldn’t find the door. We’ll go get the teachers.”

3.

A few minutes later, the school leaders and invigilators arrived. More and more people gathered outside, searching every accessible part of the outer wall but finding no door, not even a crack. A group of people chattered away.

“Strange, who built this house?”

“I was here before going to the exam room, and there was nothing here then!”

“Such a big house can’t just appear out of nowhere!”

“Could the door be on the roof?”

“A student already went to the fifth floor of the teaching building to look. They said they didn’t see anything.”

“Do you think the voice we heard might be real?”

“Shh, keep it down. The school broadcast already told us not to spread rumors and cause panic. The school leadership has reported it to the higher authorities.”

…

A female teacher asked me, “Don’t worry, we’re figuring out a way to get you out. How do you feel now?” Being in a dark, confined space for a long time made me highly anxious: “I feel like I can’t breathe.”

The teacher said, “Don’t be afraid. You are in a very large room, the oxygen is definitely sufficient, you won’t suffocate. Relax and take deep breaths.” I did as she said, but whether psychological or not, I still felt like I couldn’t get enough air.

The teachers outside made many phone calls, bringing in security and logistics personnel, but still didn’t know who built the house. “Call the fire department, tell them a student is trapped and to bring demolition tools.”

“Already called, they should be here in a few minutes.” Hearing some real progress outside, I felt a bit relieved, and breathing became a little easier. It seemed to be a psychological issue.

Soon, fire rescue personnel arrived. After determining my location, they started to demolish the wall a bit farther from me. I didn’t know what tools they were using, but I heard rumbling sounds, like hammers, drills, and chainsaws.

“What is this wall made of? We’ve been at it for a while and there’s not even a scratch.”

“Even aerospace-grade alloy materials should show some deformation.”

“Could it really be true?” a young voice tentatively asked.

“Maintain discipline!” an older, more mature voice sternly rebuked. Their voices gradually drowned out by the machines’ roar. Maybe because the rescue showed no progress, or they feared a major negative impact if something happened to me inside. More likely, they believed what the “God” had said.

Under the scorching sun, everyone was uneasy and disheartened. As time passed, the female teacher also lost her initial calm. She had to say something to distract herself: “Do you need anything right now?”

“I’m hungry and need something to eat and drink. If possible, I also need medication for the swelling and pain in my ankle.” I said calmly.

“Ah?” My response seemed to surprise the teacher, perhaps finally finding the reason for everyone’s ankle injury. But she quickly said, “Alright, eat something to maintain your strength. I’ll have a student buy you some food and medicine.”

4.

The teacher held a McDonald’s meal, and we looked at each other. She broke the burger and fries into small pieces and handed them to me through the hole bit by bit. After eating, I couldn’t help but ask, “Teacher, what about my afternoon exam?” I tried not to think about the unanswered questions from the morning. If I missed the afternoon exam, I’d definitely have to repeat the year… if I ever got out.

“Don’t worry, we’ll definitely get you out,” the teacher said, handing the drink straw through the hole. After eating and drinking, I couldn’t help but ask the director about the voice from the morning…

“It must be a prank!” she said without hesitation, but without confidence. I could see she was also frowning, looking very hesitant.

After a while, the student who went to buy medicine returned: “I couldn’t find any medicine. Everyone is hurt, and the medicine is all used up. I only got some gauze from the school nurse and a few popsicles from the store.” Luckily, these things were relatively easy to pass through the hole. I used the popsicles to cool my ankle and then wrapped it with gauze. It hurt less, though I still limped. The rescue operation stalled. They tried everything they could think of but made no progress.

The chemistry teacher took a bottle of metal gallium from the lab and poured it on the wall, but it had no effect, much to everyone’s disbelief.

“That’s something that can make most common metals more fragile than paper!” someone exclaimed.

Soon after, the chemistry teacher prepared a bottle of strong acid on-site, but it still had no effect.

Everyone’s hearts sank.

The female teacher said, “We can’t just wait around. Search carefully inside; you might find a mechanism.”

“But it’s pitch-dark in here; I can’t see anything,” I replied.

“Wait a moment,” she said, then walked away.

Only the fire rescue personnel continued their persistent efforts to break through the walls.

Soon, the female teacher returned with a flashlight and a candle.

The flashlight was too thick to pass through the hole; the candle, however, was easily handed in, but the lighter couldn’t pass through.

In the end, I had to hold the candle inside, extend the wick outside, and wait for her to light it, then quickly pull it back in.

Finally, the room was lit.

The director turned on the flashlight, and the light passed through the hole, illuminating the opposite wall and reflecting off the other walls.

I could finally see the surroundings more clearly.

It was a square room with a very high ceiling, though I couldn’t determine exactly how high.

The walls were silver-gray, looking like metal but feeling like stone. I couldn’t tell what material they were.

As I walked along the walls and observed, I found that, as they said, there wasn’t even a seam, let alone doors or windows.

Even the corners and the floor were seamless, showing no signs of construction.

Could this house have been 3D-printed directly?

With no substantial findings, I returned to the hole and noticed a new group of people outside.

They were uniformly dressed and quickly set up a cordon after gathering information from those around.

A capable woman approached me and said, “Hello, I’m Emily, the leader of the emergency response team. I’ll be taking charge of your safety and supplies. Let me know if you need anything.”

I hesitated for a long time before speaking.

“I need to use the bathroom.”

5.

The bell rang, signaling the start of the final college entrance examination. To avoid disturbing the exam, the rescue personnel stopped using noisy tools.

It was clear they had exhausted all their efforts, but they couldn’t do anything against the indestructible walls.

An hour ago, they tried to enlarge the hole using various tools, but it had no effect at all.

Later, someone thought of using a file to take some samples from the wall and the edge of the hole to test the chemical composition, but they only found fragments of the file.

Could these walls really be impenetrable and indestructible?

A whirlwind of anxiety and confusion engulfed me.

Emily, the leader of the emergency response team, seemed to sense my anxiety and tension. While methodically arranging the work on site, she also spoke to me to alleviate my emotions.

“Based on the current situation, we have no way to get you out for now, but we will keep trying. Next, we will focus on ensuring your safety and meeting your basic physiological needs inside.

“I have already arranged for an air supply system to be brought over and modified. Soon, we’ll set up a hose inside to establish air circulation.

“For water, we’ll temporarily use a water truck, which is being cleaned and disinfected. All the water will be replaced with drinking water, and we’ll use a thin hose to get it inside.

“As for food, it’s a bit more complicated. I’ve asked the chef to try to make the food into long strips. You can tell us what you want to eat later.

“The lighting issue can be solved right now.”

As she spoke, another staff member handed a long light strip through the hole.

The light strip, already connected to a circuit, emitted a soft orange-yellow glow. The back was covered with double-sided tape.

“First, pull the entire light strip inside and place it along the edges of the four walls. After ensuring the length and position, remove the double-sided tape and stick it about a meter high on the wall.”

Since the room was now lit, I easily completed the task, even though it was crooked.

Due to the need for continuous power supply, the wire occupied part of the hole.

Emily handed me a pair of Bluetooth headphones: “We have prepared a phone outside that is connected to these headphones. We can keep in touch, so you don’t have to shout loudly, even if you are far from the hole.”

Great, this device made me feel connected to the outside world and modern society again.

“If the headphones run out of battery, just pass them to us, and we’ll replace them with another pair,” Emily’s voice came through the Bluetooth headphones.

“As for the bathroom issue, we’ll have to continue using sealed bags for now. We’ll find a way to decompose the waste and extract it later.”

“Now there are two more problems. We can’t send a bed inside, so we can only provide some thin gauze. You’ll have to manage, but fortunately, it’s summer now.

“The other issue is that we can’t send a computer or phone inside for now. What do you usually do for entertainment?”

I thought for a moment: “Reading novels and listening to music is enough. Novels can be in audiobook mode, and I can listen with the headphones.”

“Sure, what type of novels do you usually read? I’ll get someone to find some for you.”

Emily immediately coordinated the related tasks.

Soon, Emily handed me many O-shaped objects through the hole.

“These are for fixing the air ducts to the wall. They have double-sided tape; just clip the hose and stick it to the wall,” Emily explained.

Then, the staff handed me a 9 mm diameter rubber hose.

To pass it through, they had to cut the light strip’s wire first, install a switch outside the wall, and then reconnect the indoor wire to the switch.

“This way, the wire won’t continuously occupy the hole’s space. When sending larger items, we can detach it first, then reconnect it after the items are inside. It’s very convenient,” she explained.

“Now, you need to fix the rubber hose to the wall, starting about 20 cm from the hole and extending to the farthest point.”

Following Emily’s instructions, I quickly completed the task.

The hose was very long, extending to the center of the wall opposite the hole. It seemed they had calculated the length in advance.

Next, she handed me a hose with a diameter of less than 5 mm, with a metal fitting at one end, also about 9 mm in diameter.

I immediately understood its purpose and connected the metal fitting to the hose inside the room.

Meanwhile, the staff outside completed the other end’s assembly, and the air supply system soon began working.

“The machine outside filters the air and pressurizes it inside, allowing natural air circulation. Excess air will exit through this hole,” Emily explained.

“I originally thought of supplying oxygen, but the technicians told me that high concentration oxygen can cause poisoning. Supplying air is sufficient.

“We will later customize mini monitoring devices to monitor the air quality inside. For now, we’ll send in a thermometer.”

She handed me an electronic pen-type temperature and humidity meter.

“If there are any anomalies in temperature or humidity, let us know. The air supply system can control the air’s temperature and humidity, and we can adjust the indoor environment from outside.”

Her words eased my mind, knowing I wouldn’t suffocate or overheat in here.

Seeing that there was no urgent matter, I asked Emily, “What do you think about that ‘God’ figure?”

She also relaxed a bit, smiling slightly: “I admit, today’s events have indeed exceeded our previous understanding. We can’t explain it with our current knowledge.

“But this also means we have the opportunity to discover the secrets behind it and gain higher-level technology and knowledge.

“Do you know what that means?” she asked me slyly.

Without waiting for my answer, she continued, “It means that whether it’s a god or an alien, from the moment they appeared, they became our research subjects.”

6.

By nightfall, Emily had already arranged for the water supply equipment to be prepared.

Like the air duct, they first sent in a 0.9 cm diameter water pipe, which I installed near the hole.

Since water is heavy, it might not be secure to stick the pipe horizontally on the wall. Instead, I simply placed it vertically below the hole.

When using it, I connected the internal pipe to the external one with a small L-shaped metal pipe.

The top of the pipe had two metal sections. By holding the outer one and twisting it clockwise, water flowed out; counterclockwise turned it off. It was a very convenient faucet.

To prevent water from pooling on the floor, the staff handed me many sealed bags.

The bags were color-coded: green for drinking water, white for wastewater, and yellow for waste.

To handle wastewater and waste, they also sent in small packets of decomposition deodorizer and fully degradable tissues.

I had seen this deodorizer in short videos before. Some RV travel bloggers poured it into the toilet after use. It could decompose solid organic matter into odorless and harmless liquid.

With this, I no longer had to worry about being surrounded by my own waste.

Of course, decomposition alone wasn’t enough. We also needed to regularly extract the wastewater with a hose.

Since the wastewater might contain some undecomposed solid particles, which could cause blockages, we couldn’t use the combination of thick and thin pipes like the air and water ducts.

Instead, we had to remove other pipes and wires to fit a one-centimeter hose for extracting wastewater.

Nevertheless, the problem was finally solved.

Although the sun had set, the hole was still illuminated by a glaring light.

The staff outside tirelessly continued their work, modifying machines, installing equipment, and unloading what seemed to be prefabricated building components.

Given the situation, it seemed likely that this would be a long-term operation. They were probably building some structures outside the secret room for office and residence.

Am I really going to stay in here until I’m 70?

In this place?

For 50 years?

Are you kidding me?

Though hard to accept, I had no way to solve the problem and could only place my hopes entirely on those outside.

All I could do was live well, avoid injuring myself, and not mess up the secret room’s ecosystem.

“It’s now 8:30 PM. We have prepared some toiletries for you. Come to the hole to get them,” Emily’s voice sounded in my headphones.

I walked to the hole, and the staff temporarily removed a few pipes and wires, handing me a toothbrush, toothpaste, and a disposable face towel.

The disposable face towel was like a small white pill, which would turn into a towel when soaked in water.

The toothbrush and toothpaste were small and looked like hotel amenities, but of much better quality.

I asked Emily about them through the Bluetooth headphones.

She explained, “These are high-quality hotel amenities. Be gentle while brushing your teeth.

“And the face towel, though disposable, isn’t degradable. Until we find a better solution, please reuse it as much as possible to minimize solid waste.

“As for bathing, it’s not feasible for now. Too much water in such an enclosed environment would increase the air humidity.

It’s hard to balance the dried wind, so use a disposable face towel to wipe yourself down first. We’ll find a solution as soon as possible,”

Emily finished speaking, and by then I had almost finished washing my face and brushing my teeth.

Although some water had splashed onto the floor, it was minimal and shouldn’t matter. It was uncomfortable not being able to take a bath, but I used the disposable face towel to clean myself. Looking at the dirty clothes on the floor, I was at a bit of a loss.

“I’ve sweated a lot today, and my clothes are dirty. Is there a way to deal with this?” I asked. “Wait a bit, we’ll figure something out,”

Emily’s calm voice came through the Bluetooth earphones. About half an hour later, Emily notified me to go to the 1 cm diameter hole to get something. I hesitated for a moment, then put on the dirty clothes before walking over.

After removing all the pipes, a cylindrical object, perfectly fitting the hole, was sent in from outside, followed by two more.

I weighed them in my hand, unsure of what they were, so I asked her, “What is this?” “Clothes, vacuum-sealed in a vacuum-sealed bag.

Just open the bag, and you can use them.” I handed the wire out, and the staff connected it to the power supply.

Once the light strip was powered on, I followed her instructions to open the three bags, and sure enough, there was a set of soft clothes inside. I quickly changed my clothes and handed the vacuum-sealed bags back out through the hole.

Just as I was about to reconnect the remaining pipes, Emily asked me to stop and sent in some more items. “Earlier, we gave you some common medicines. The names, uses, and dosages are written on the boxes, but you must tell me before you take anything and wait for a professional doctor to confirm it’s okay.

If you feel any discomfort, let me know at any time. “These bags contain disinfectant. Disinfect your hands and feet every day to prevent fungal and parasitic infections. This is important. “

Lastly, this is an inflatable pillow. Open it and find the inflation port. We’ll help you inflate it with a metal tube. Let us know when it’s sufficiently inflated, and we’ll close the valve. Then you can tighten the inflation port.”

After handling these tasks, Emily told me it was almost ten o’clock and suggested I go to bed early. I felt like I had gained a 24-hour personal assistant, but it didn’t make the isolation any less suffocating.

As I lay down on the thin gauze and inflatable pillow, I found it impossible to sleep. I looked around and found the pitch-black secret room so empty. The supplies meant to ensure my survival felt like mere decorations in a desolate desert, unable to change the fact that this place was unfit for living.

The warm yellow light from the surrounding light strip illuminated the hard contours of the secret room. The towering ceiling made me feel like I was at the bottom of a deep well, amplifying my anxiety. After tossing and turning for over an hour, I still couldn’t sleep.

“Having trouble sleeping?” Emily’s voice came through the Bluetooth earphones. I couldn’t help but be curious: “How did you know?”

She didn’t answer my question but suggested I think of relaxing stories or play some soothing music or boring stories. If needed, she could even have a math teacher give me a lesson.

“Does everyone else have to stay awake if I can’t sleep?” I asked, voicing my suspicion.

Emily was silent for a moment, weighing the pros and cons, before finally telling me the truth: “That’s correct.

Don’t let it stress you out; just try to go with the flow.” “Play some white noise for me, please. Thank you.” Although I still found it hard to sleep, I eventually drifted off after much tossing and turning.

7

When I woke up, I had no idea what time it was. Feeling a bit cold, I pulled the thin gauze over myself. Within a minute, Emily’s voice came through the Bluetooth earphones: “You’re awake?”

“Yes. What time is it now?” “It’s six-thirty. Your biological clock is quite accurate.” After washing up, Emily told me to wait a bit since everyone else had just woken up, and breakfast wasn’t ready yet.

While waiting, I discussed the work and rest schedule with her. She explained that everyone on Earth now had to follow my schedule, so it needed careful consideration. When I sleep, others would naturally fall asleep too.

If someone was driving or engaged in high-risk work, it could be very dangerous. “Did I cause any trouble last night when I fell asleep?” I asked, concerned.

“Don’t worry, we issued warnings through various channels in advance, so most people received the notice. We didn’t have significant issues on our end.” “What about other places?” I could sense the implicit meaning in her words.

“There are always countries and regions we can’t notify or those who don’t take it seriously. In some remote countries, even if we notify them, they may have difficulty disseminating the message to their citizens.

Additionally, some countries are in opposite time zones; when it’s night here, it’s day there.” Emily’s tone was almost devoid of personal emotion, likely to avoid adding to my stress.

My mind immediately went to the countries on the other side of the Earth. When I sleep, it’s their active hours. Now that I’m awake, the sun is setting there. I thought mischievously that if my schedule was precise enough, I could keep them from seeing the sun for a long time.

Despite my playful thoughts, I still asked Emily for her opinion: “Should I adjust my schedule to give those countries some daylight?”

“The higher-ups said not to worry about it for now. Just stick to our traditional schedule.”

After breakfast, Emily outlined my day’s plan. First, my original set of dirty clothes, which were thicker and made of harder material, couldn’t be sent out through the 1 cm diameter hole like last night’s change of clothes.

We had to find a way to dispose of them to prevent odor from affecting the air quality. The staff sent in a set of disassembled components, which I assembled into a pair of scissors.

I used the scissors to cut the dirty clothes into small pieces and passed them out through the small hole.

Then the staff sent in a rolled-up flexible touchscreen, which, when unfolded, was about the size of a tablet, likely around ten inches.

Under the guidance of the technical staff, I connected the related components to the flexible touchscreen and adhered it to the wall, then connected the wires to the external equipment.

“We’ve installed some video, game, reading, music, and learning software on the device. You can use them directly, and the sound will come through the second set of Bluetooth earphones we gave you. “

In principle, you can use these apps freely, but you need to control your usage time. For your health, we have staff monitoring your electronic device usage. If it affects your health, we may impose some restrictions.”

I wanted to open the browser to see what earth-shattering changes had occurred outside, only to find there was no browser.

Emily explained, “The internet is chaotic right now. We don’t want you interacting with others online, for both your well-being and theirs.”

I thought about it and agreed. No need to stir up trouble. Playing games on a flexible touchscreen wasn’t ideal either. Most importantly, knowing someone was monitoring my activity, I didn’t want to expose my novice-level skills.

It would be better to study, easing my anxiety and leaving a good impression on those outside.

By the afternoon, the staff had combined the light strip wires and the flexible touchscreen wires into a single line, with two connectors at the end, one for each device. It indeed looked much tidier. Having exhausted myself with studying, I decided to watch a movie. I could finally binge-watch all the films I had wanted to see but never had the time for.

After one movie ended, Emily’s voice sounded: “Time for some exercise.” The screen went dark.

Though I was reluctant, I followed her instructions and exercised for a while. Before evening, Emily sent in a specially designed daylight lamp. This was an artificial sunlight LED lamp typically used in mines.

Coal miners, who spend extended periods underground without sunlight, use these lamps to prevent occupational diseases.

The power interface for the lamp matched the light strip’s, so I only needed to unplug the light strip and connect the artificial sunlight LED lamp.

Over the next few days, Emily and her team helped me solve various small issues. After a week of this well-served but entirely unfree life, I was on the verge of a breakdown.
