"What else could it be?" The female Jinyi Liuye drooped her eyebrows and was very frustrated: "Did he really create a method of his own? In that case, who could guess?"

Qi Ping suddenly said: "No, it is really possible."

Seeing everyone looking at him, he explained:

"I suddenly thought of a question. If the account of No. 13 represents unsent intelligence... and the account of No. 10 corresponds to the message he sent to Hongye, then is this correspondence in itself?

Can you reversely deduce the compilation method?"

Everyone was stunned.

This logic is not difficult to understand.

Anyone who has studied mathematics knows that it is like giving you two strings of symbols and telling you the "plaintext" corresponding to one of them, asking you to find the pattern and deduce the "plaintext" represented by the other string.

Although the captains in Jinyi are not good at arithmetic, they still understand this.

Qi Ping's eyes are getting brighter and brighter:

"If this is the case, the scholar sent the information and key to Hongye in advance, which has a second meaning. I thought before that he was preparing for possible dangers and giving the key was to facilitate Hongye's entry.

But...it's just a wooden door, how could it stop a spy?

Therefore, the key is not the key, the meaning it refers to may be what the scholar really wants to say."

meaning?

What does a key mean? Of course it means unlocking a lock...it can also be extended to unlocking a password.

is that so?

Everyone suddenly realized and became excited again. Hong Jiaojiao's eyes were bright:

"In other words, as long as we get the original intelligence text he sent to Hongye on the 11th, we can possibly find the pattern of the code?"

Yu Qing slapped the table: "What's the original text?"

I don't know, I've never seen it, I've only heard what they said... Qi Ping shook his head, thought for a while, and said:

"There is no practical significance in sitting here and speculating. I think we should go to the scene. Hongye and others are also there. Whether we start with coding or looking for code books, the bookstore is the key point."

"Then what are you waiting for?" Hong Jiaojiao slapped the table and stood up, wishing she could spread her wings and fly over.

"Shall we go directly? Will there be any problems if we are exposed?" Pei Shaoqing pointed out calmly.

Qi Ping shook his head:

"It doesn't matter, everyone is missing, why are you afraid of being exposed? In fact, I originally planned to take you there at night. Although Hongye said they have searched, there may not be any omissions. Just like this account book, it was missed.

So, I need you to go together and check it again."

Everyone accepted this reason and immediately left, preparing to set off.

However, at this moment, Qi Ping suddenly stopped the captain with a loud voice who was about to leave:

"Lao Hu, please stay here for a moment. I have something to tell you."
