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

On the morning of the sixth day, Lu Chenggong went to check his registration.

It's not cell number 31.

It's the line with his name in the current registration.

That line originally had a note added: "[I was unaware of this registration and hereby decline to accept it.]"

Now, there's another line of text after that line.

He didn't write it.

It wasn't written by Xu Wangshu either.

"Who wrote it?" he asked.

"I don't know," Qin Lan said. "I checked this morning, and it was there."

That line of text was very short.

He stands here because no one stood for him back then.

Lu Chengong stared at the line of text for a long time.

"What does this mean?"

"The literal meaning," Xu Wangshu said, "Someone spoke up for you."

"Who?"

"I don't know," she said, "but the sentence didn't say you were number thirty-one. It said why you're standing here."

Lu Chenggong remained silent.

He placed this line of text alongside the three scratches on the bottom of the thirty-first grid.

After a while, he suddenly understood something.

“This line of text,” he said, “is written in the same handwriting as those three lines in Gedi.”

Qin Lan went to compare.

After comparing them, she nodded.

"It seems so."

"Then it wasn't written by Number Thirty-One himself," Lu Chengong said. "Number Thirty-One wouldn't write 'No one stood up for you back then' for himself."

"Who is that?"

Lu Chengong looked at the line of text.

"They were there back then, but they just watched and didn't offer any help," he said.

The main control room fell silent.

Xu Wangshu did not react immediately.

She did something.

She noted down the appearance of this line.

After finishing writing it down, she asked Lu Chenggong, "Do you recognize this line of text?"

"What do you mean?"

"If you acknowledge it," she said, "it becomes your statement. If you don't acknowledge it, it remains a statement of dubious origin."

Lu Chengong thought for a while.

"I don't acknowledge it," he said.

Why?

"Because not a single word was written in front of me," he said. "If I didn't see it written down, I couldn't recognize it."

Xu Wangshu nodded.

"Then just ignore it."

"It is written: The current registration number is 31, and a second line of annotation has appeared. The person who added the annotation is unknown, and I did not personally witness its generation, so I do not consider it to be my own statement."

"Should we keep this line of text?"

"Keep it," Xu Wangshu said. "Keeping it doesn't mean I accept it."

Qin Lan added another reminder.

"The handwriting in this line is similar to the three marks left on the scraped-out paper from back then," she said. "Should we merge the cases?"

"No," Xu Wangshu said.

"Why not merge?"

"Because combining the cases is tantamount to drawing a conclusion," Xu Wangshu said. "Now we only know one more thing: the person who wrote these two passages may be the same person."

"Isn't it enough to conclude that it might be the same one?"

"That's not enough," Xu Wangshu said. "Similarity doesn't mean it is. People can remember 'similar to the same stroke,' but they can't remember 'it is the same person.'"

After listening, Lu Chenggong suddenly asked, "Then, does that mean my line of work has been compromised?"

"That's fine," Xu Wangshu said. "So now you have two lines. One is your own refusal, and the other is something someone else wrote for you."

"If we put the two rows together, whose word counts?"

"Yours," Xu Wangshu said.

Why?

"Because you are the person," she said. "If I didn't see the words written, I can choose not to recognize them. No matter how many lines others write, they can't outshine your line 'Refusal to Resign'."

Lu Chenggong read the line of text again.

He stands here because no one stood for him back then.

He didn't say anything more.

But everyone could see that he hadn't been able to immediately banish those words from his mind.

Xu Wangshu could also see it.

She just didn't point it out.

She only added one last line at the very bottom of the record.

[Anyone who comes can add to the statement, but I may not acknowledge it. No matter how many additions are made, it will not change my statement.]
