Don't go to the moon, there are gods on the far side of the moon.

Chen Rui folded the hand-drawn diagram of the injury and stuffed it into a sealed bag. For the first time, he felt that the repair team could leave a more reliable record than surveillance footage, and could even save lives.

Old Zhou had a dark ring around his ankle, like it had been bound by a very thin thread. The medic wanted to take a picture for record-keeping, but Xu Wangshu stopped him and suggested a hand-drawn record instead. Not all wounds are suitable for being illuminated by a camera, especially after they had just learned that the thing outside the door could see light.

After the archivist came out, she kept clutching her cane, repeatedly confirming that she hadn't read the contents aloud. Qin Lan asked the medical team to give her a blanket first, without pressing for details. Xu Wangshu only recorded the person's condition: fright, exhaustion, and still able to respond. She wrote very slowly, as if reminding everyone that the copper plate they brought out was important, but the person they brought out was even more important.

The rescue workers outside the ventilation shaft didn't use headlights, only a small dark area enclosed by a blackout tarpaulin. Chen Rui knelt at the shaft opening, his fingers trembling so badly he grasped at nothing several times, but he couldn't loosen Lao Zhou's belt. After Lao Zhou was dragged out, he first slapped Chen Rui on the head: "I told you not to pull my waist, not to pull my pants down." Chen Rui almost held back his tears. Everyone knew he could still swear; at least he hadn't been corrupted by what was written in the dark storage room.

Outside the dark warehouse, Wen Qingyue's expression finally changed.

It was as if she already knew it wasn't clean inside, but she didn't realize it was this dirty.

Qin Lan immediately ordered: "Stop reading, evacuate personnel."

But Old Zhou's voice came soon after.

"No, there are some by the door too."

"What doorway?"

"Eyelien." Old Zhou was breathing heavily. "It wasn't there before, but now I can feel a layer growing on the crack in the door."

The temperature in the main control cabin seemed to drop a few degrees.

Xu Wangshu quickly pulled out the construction plans for the Lightless Library. It was a purely mechanical structure, with only a graphite sealing layer on the inside of the door seams, making it impossible for anything to grow there. Unless the so-called eyelids weren't biological tissue, but rather the outer shell's file's response to being "touched."

"Old Zhou, don't describe the appearance."

"I didn't see it."

"Less talk about the feel."

Old Zhou gave a wry smile: "Fine, then I'll speak like a human. It doesn't want me to leave."

The archivist let out a suppressed sob beside her. She had received training in reading the blind, but her training was with tattered papers, metal nameplates, and old-fashioned tapes—not things that would close under her fingers.

Lu Chengong ripped off the monitoring cable.

"Open the door."

The medic held him down: "You can't move!"

"If we wait any longer, it will be gone."

The toolbox flashlight suddenly started flashing rapidly.

Don't open it.

Upon seeing these two words, Xu Wangshu immediately pressed down on Lu Chengong.

"We can't force it open. If an external light source shines into the lightless library now, the things inside might get a complete location."

Lu Chenggong's eyes reddened: "Then let Old Zhou grope himself to death inside?"

"no."

Xu Wangshu enlarged the Wuguangku drawings to the ground structure.

"Lin Wangchuan left behind a maintenance well."

Wen Zhaolin was stunned: "Impossible, I was involved in the design."

"So you don't know." Xu Wangshu pointed to a thin line marked as redundant drainage. "This isn't drainage; it's a blind drainage channel commonly used in the old-style artifact storage of the exhibition hall. Zhou Jianguo understands."

Old Zhou heard this in the cable TV channel and immediately cursed.

"That old fox, Lin Wangchuan!"

Xu Wangshu spoke quickly: "Take half a step back with your right foot and feel the third coarse crack in the ground. There should be a reverse-locked nut inside. Don't use metal tools; use your fingernail to pry it open."

"My nails aren't that long."

Chen Rui suddenly interrupted, "Hey sir, your shoes! There's a pry bar in the heel of your old work shoes. You put it there yourself when you were repairing the display case!"

Old Zhou was taken aback, then laughed and scolded, "You brat, I always tell you not to look around, but you actually do."

A dull rustling sound came from the dark storage room.

The archivist's sobs grew closer.

"Master Zhou, the cabinet is moving."

"Ignore the cabinet," Old Zhou gritted his teeth. "Touch my shoulder and squat down with me."

Everyone in the main control cabin was focused on the two vital signs.

Suddenly, a heartbeat noise came from Lin Jibai's toolbox.

Xu Wangshu immediately turned around: "You're not allowed to answer."

The screen lights up.

I heard Dad screwing in the screws.

"You are not allowed to cross the line."

[All I hear is the sound of screws.]

Xu Wangshu knew how dangerous those words were. If Lin Jibai's Heavenly Pillar Echo followed the structure of the Lightless Library, it could be located by the external archives. But without him, Old Zhou might not be able to find the mechanical escape route that Lin Wangchuan had hidden in the darkness.

She paused for a second, then rewrote the restrictions.

[Lin Jibai is permitted to read the echo of the mechanical structure without light.]

[Access to the file is prohibited.]

[Do not respond to requests from outside the shell.]

[The entire process was manually stopped by Xu Wangshu.]

The toolbox flashlight is on.

【confirm. 】

The next second, Lin Jibai's stability dropped from 43 to 41.

He heard it.

It's not an eyelid, not a cabinet, not the eye outside the door.

It was the sound of my father, Lin Wangchuan, squatting under the floor of the dark warehouse many years ago, slowly chiseling open the hidden groove with his hand drill.

Lin Wangchuan seemed to be in darkness at that time as well. He didn't turn on the light, but relied on his hands to feel the threads and insert an old-fashioned reverse nut.

Someone nearby asked, "Is it necessary? The lightless vault is already safe enough."

Lin Wangchuan replied, "Talk about safety is usually something that's said before an accident happens."

That person looked like Wen Zhaolin in his youth.

"You always leave yourself an escape route."

Lin Wangchuan chuckled.

"It's not for myself, it's for the unlucky ones who will get dragged into this mess by you later."

Lin Jibai chuckled silently inside the toolbox.

Dad, you really know them well.

He tapped out the spiral rhythm he heard to Lao Zhou.

For a moment, pause for half a beat.

Twice, twist in the opposite direction.

Three times, press down.

Old Zhou did as instructed immediately.

A very faint clicking sound came from the ground.

"It's open!"

At the same instant, the words on the outer screen of the lightless library reappeared.

The reader is leaving.

[Do you want to retain the replay feature?]

Qin Lan said coldly, "No response."

In the darkness, the archivist suddenly said, "It touched my face."

Old Zhou roared, "Dowry your head!"

His vital signs fluctuated violently. The mechanical outlet at the bottom of the ventilation shaft was manually pried open by outsiders, and a blast of stale, cold air shot out. Old Zhou first pushed the archivist out, and as soon as half of his body was sticking out of the shaft, his ankle felt like it was being held down by something.

Chen Rui rushed up and grabbed him.

Old Zhou cursed in pain, "Don't pull my legs! Don't pull my back!"

Lu Chengong finally couldn't hold back any longer, pushed the medic aside, and pressed down on the physical assistance area outside the broken bow stabilization shield.

"I won't shoot."

He said, "I only pick up people."

The broken bow fragment trembled slightly, and a very thin, crimson line fell onto the ventilation shaft opening. It didn't look like an arrow; it looked more like an old rope. Chen Rui grabbed the rope and, together with the external rescuers, pulled Old Zhou out.

A soft closing sound came from inside the black door of the Lightless Vault.

Like a giant eye, it closed again.

Old Zhou lay on the ground, his face pale, his right hand tightly gripping something.

Qin Lan immediately asked, "What did you bring out?"

Old Zhou spread his hands.

That's neither paper nor a metal nameplate.

It is a Braille copper plate.

There is only a short row of bumps on the copper sheet.

After the archivist finished touching the surface, he translated in a trembling voice:

"Outside the North Heavenly Gate, do not look at the name, only at the light."

Xiaoman's blanket slipped off her shoulders.

Xu Wangshu suddenly looked at the ray of morning light by the window.

On the toolbox screen, Lin Jibai typed out a sentence very slowly.

Close the window.
