Zhu Shu hurriedly went upstairs and returned to room 304 where Lu Yuwen was.

Su Man and Bai Youwei are there.

"How? Did he see it? Su Man couldn't wait to ask.

Zhu Shu carefully closed the door, then faced Su Man and Bai Youwei, and nodded affirmatively:

"I glanced at it and there were some scraps of paper on the table, which he must have torn."

Bai Youwei said: "It seems that he does know Chinese characters, and since he knows Chinese, it makes sense to be able to make code codes in Chinese." ”

"Shall we tell the Inspector?" Su Man looked at Bai Youwei and then at Zhu Shu, "Tell the detective and let the detective arrest him?" ”

"If you don't even have evidence, how can you be arrested?" Bai Youwei shook her head slightly, "He can completely deny it, and then make up a random reason for himself to get out." In short, the current situation is that even if we can almost confirm the identity of the mastermind behind the scenes, there is no way to convict the other party, and more evidence must be found. ”

Su Man grabbed his hair worriedly, "Ah! How do you find it...... Those guys are better than the other, and they can't catch them at all! ”

Zhu Shu also furrowed her eyebrows in embarrassment, and said in a low voice: "Our task is to help the detective find the five murderers, even if we arrest him now, it is useless, as long as there is any fish that slips through the net, all the efforts will be wasted......

"That's right." Bai Youwei nodded, "To find out five people to meet the winning conditions, one can't find one, and only one is missing and can't be found, the result of both is the same." ”

She took out half of the slip of paper from her coat pocket, checked the information she had copied on the paper, and placed it on the table together.

"If we can figure out the true meaning of these words, we may be able to find an opportunity to counterattack."

"Although that's what I said...... Su Man looked at the words and couldn't help sighing, "I can't understand it at all......"

The words on the half-cut note were:

【Siege, Solidity, Circle, Circle】

The words Bai Youwei copied from the wall were:

【四·囨回·囨囬園·四囝囨因囬園园】

【囡·四囝囤囤·图回淝寀園

Bai Youwei circled the second half and calmly analyzed:

"The text on the wall, at the end, is exactly the same as the text on the half-cut note.

I think it should be Lu Yuwen who interrupted the other party's message transmission and made them realize that the original method was not safe enough, so they changed their strategy and deliberately posted the code openly in a place where everyone could see it.

In this way, the information can be transmitted smoothly without worrying about being seen through, and it can also cause a series of tensions...... Humans, the more nervous they are, the more likely they are to make mistakes. ”

Zhu Shu looked at the words, her eyebrows furrowed, "If it is the kind of password with the mother book, no matter how we study it, it is impossible to study the results." ”

Su Man asked her, "What mother?" ”

"It's something that can decipher a code, usually a book." Zhu Shu explained, "Assuming that each character represents a page number in these characters, then you only need to open the page of the parent book to find the corresponding word." ”

Su Man's face became more and more ugly, "...... Then we don't have a mother's capital, won't we lose? ”

"Don't worry, it won't be too complicated." Bai Youwei said lightly, "Once this kind of thing is brought into the game, it is a handle, and it is easy to be discovered, I think there should be a simpler solution to these text passwords." ”

Zhu Shu sighed: "I've tried to split words, homophonic words, reverse the order, all useless, no matter how you solve it, you can't solve a useful piece of information." ”

Bai Youwei thought for a while and thought thoughtfully: "Although it is Chinese, the other party is a foreigner after all...... Perhaps, we are thinking too complicated. ”
