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

On the sixth night, the eavesdropping client on the DreamNet made its first move.

Xiaoman didn't hear it.

A line of text popped up on the big screen first.

It wasn't sent by someone from the human world.

It wasn't issued from Beitianmen either.

It came from the direction of the door to the counterweight compartment.

There are only five characters.

I stood there.

Everyone in the main control room stopped.

Xu Wangshu was the first to react.

Is this really me?

"I don't know," Xiaoman's voice came from the listening end, "but these words came from that door. Not from the outside, but from the inside."

"in?"

"Yes," Xiaoman said, "He stayed inside the door the whole time."

Qin Lan immediately retrieved the relevant information.

"Impossible," she said. "We've been inside more than once, and it's always empty."

"What you see is emptiness," Xiaoman said. "You didn't reach the place where he was standing."

The main control room was quiet for a while.

Lu Chenggong suddenly spoke.

"Square number thirty-one," he said. "That square is knee-lower than the one next to it."

"Yes," Xu Wangshu said.

"When we measured, we measured from the top," Lu Chenggong said. "We didn't measure—behind that grid."

Everyone looked at him.

"Behind the grid is a wall," Qin Lan said.

"It's a wall," Lu Chengong said. "But the door that says 'The Fire Keeper is Here' is also on the wall."

No one spoke in the main control room.

Xu Wangshu slowly exhaled.

"So we always thought that number 31 was registered on the list."

"Isn't that right?"

"That's possible," she said. "But the place he stood in was earlier than the list."

She walked to the record and picked up her pen.

She paused before writing.

Because once this was started, the direction of Volume 6 changed.

Number 31 is no longer just a "name that has been erased".

He became someone who could speak for himself.

She wrote the first line.

On the sixth day, writing came from inside the counterweight compartment door: "I stood there." The source was inside the door, not in an empty area, suggesting there might be unexplored space.

She thought about the second line for a long time.

People don't bother to ask who he is.

[This one space will remain in the human world forever.]

After she finished writing, she put down her pen.

"Reply to it."

"Return to what?"

"Just one sentence," Xu Wangshu said.

"We'll wait until you finish speaking."

Qin Lan asked, "Aren't you going to check what's behind that door?"

"No investigation."

Why?

"Because whoever is behind the door has to come out and say it," Xu Wangshu said. "It's the same as us tearing down the wall and going in ourselves versus us filling out forms for someone else."

Lu Chengong understood and nodded.

"Then we'll stay outside."

"Yes," Xu Wangshu said. "Keep the lamp, keep the stool, keep the shelf."

After those five words were sent, there was no reply from inside the door.

But for the first time, the temperature at level thirty-one remained steadily.

Not hot, not cold.

It's like someone finally taking their hands off the board and standing up straight.

Xiaoman, who was listening nearby, said something softly again.

"Someone laughed just now from inside the door," she said.

"What are you laughing at?"

"I don't know," Xiaoman said, "but he wasn't sneer."

Xu Wangshu also thought about those words.

“From tonight onwards,” she said, “this section will no longer be called ‘To be completed’.”

"What's it called?"

"It's called 'already someone'," she said. "There is someone, but they haven't finished speaking yet."

"How will we explain this to Beitianmen?"

"Report truthfully," Xu Wangshu said. "Report: 'At position number thirty-one, someone announced, "I stood there.' The person did not give their name, so no one can identify them. Leave the position vacant."

After listening, Lu Chenggong asked a question.

"So, have we made contact with him?"

"No," Xu Wangshu said. "He only said one sentence."

"Even a single sentence counts, right?"

"In short, it only means the door has been opened," she said. "The door is open, but the person hasn't come in yet. Until they come in, they are still outside."

The darkness outside the window also stirred slightly at that moment.
