The reason why Li Zimu didn't want these people to know the secret about the wordless seal, although he also had a little selfishness in it, but he still wanted to protect them. The husband is not guilty, but he is guilty. If you don't have enough ability, it will become a burden.

What's more, this thing is just a legend, how many legends are true?

"There's still a piece of cloth on this," after Li Zimu put the things away and put them in the bag, Zhang Jingyang took out a piece of cloth from the box and held it in the palm of his hand and said, this material is very comfortable to the touch, and it is very light, it is by no means a linen cloth, and the four corners are neatly folded in the middle.

When he took it out and spread it out, he realized that it was not a cloth used for padding, and there were words on it.

"It turned out that it wasn't a cloth for padding, this is a silk book...... Zhang Jingyang spread out the cloth little by little, but he didn't expect the cloth to be a little wide, and something was painted on it.

"What is it written? Is it written by Ying Zheng?" Wang Xueling said with her head closer, because she was educated by her father since she was a child, and she was still more interested in history.

"These are two pieces of silk book" Zhang Jingyang said in surprise, he said why is this piece of cloth so thick, it turned out to be two pieces of silk book overlapped and combined into one, the material of this silk book is not silk material to the touch, it is about the same thickness as linen, but it is softer and more delicate than linen.

Zhang Jingyang tore the cloth into two copies of the same size, squared the two silk books on this low table, and the four of them held flashlights together to discuss.

"This is the map of the Jieshi Underground Palace, but it is more detailed than the one we took in the attic of Zhang Han, you see, this is a secret passage, and there are two," Zhang Jingyang said as he carefully observed the first silk book.

The things drawn on this silk book were similar to the bamboo slips they had found in the attic where Zhang Han lived, so Zhang Jingyang could see at once that this was a map of the Jieshi Underground Palace.

The difference is that this silk book is painted on more than the bamboo slip, that is, the passage in front of the Jieshi Underground Palace, what makes them happy is that it not only draws the passage, but also draws the distribution of the secret passage and the method of opening the secret passage in detail, which is undoubtedly what they need most now.

"One of these two secret passages is the passage that leads to the Wanhe Hall from the Phantom Sound Magic Tower, and this should be the passage that Xue Ling took before, but she can't remember it" Zhang Jingyang pointed to a piece of this silk book and said, according to the content of this silk book, this secret passage is next to the platform in front of the Phantom Sound Magic Tower, which can explain why Wang Xueling was able to disappear in just a few minutes.

"And this other secret passage is at the place where the stone steps from the Baijia Prison come from, all the way to the outside of the first door we first entered," Zhang Jingyang then pointed to another secret passage and said, which was marked with Chu Seal clearly written, and could be seen at a glance.

These two passages are actually supposed to be connected together, but because they pass through a crater in the middle, they become two, and no matter how you go, the air passage is also a necessary way.

"Why Chu Seal? Shouldn't it be Qin Seal...... Wang Xueling asked suspiciously, Chu Seal, as early as after Qin unified the Six Kingdoms, Yingzheng unified weights and measures, and began to use Qin Seal, but why is the words on this silk book written in Chu Seal?

"Couldn't it be someone else's ......" Li Zimu shook his head and said, this silk book should have been drawn by Xiang Yu, because this font is the same style as the sixteen big characters on the side of the door when I first came in, and it should be from a person's hand.

"That's right, it's our preconceived ideas...... Zhang Jingyang smiled and said, it was their thinking that they were preconceived, thinking that everything in it should be Yingzheng's things, and this silk book should also be written by Yingzheng, so they didn't figure it out for a while.

"In this case, this is most likely the silk book left by Xiang Yu, so why did he do this?"

"Look at what is written on the second silk book, maybe you can find the answer" Wang Xueling nodded and said, they have two silk books, maybe the answer is on the second silk book.

Zhang Jingyang shook his head with a wry smile and put another silk book in front of several people.

"Is this a font?" Wang Xueling asked after a closer look, there were dense things written on the silk book, judging from this typesetting format, it should be a paragraph, but the problem is that this character is neither Chu Seal nor Qin Seal.

"I don't understand it either" Zhang Jingyang shook his head and said, he also looked at this silk book carefully, it was not a seal script on it, it should be the script of other places at that time, after all, before the unification of the script of the Qin State, the scripts of other countries were different.

"Don't look at me, I can't understand it" Li Zimu shook his head and said casually, but his heart had already fallen into deep thought, this silk book is indeed a paragraph, and he did understand the content of this silk book.

"Maybe it's the text of other countries, I'll go back and check the information" Zhang Jingyang nodded and said, without the slightest doubt about what Li Zimu said, after all, the latter is not omnipotent and knows everything.

The second silk book was carefully folded and put into the bag, and after the four of them turned around to make sure that there was nothing else, they planned to leave this stone dungeon, and now that they had the secret passage map in their hands, it was much more convenient.

Each country has its own unique secret to transmitting its own information, just as the secret information of each country is now encoded with unique characters created by itself, and only its own people can know what is recorded in it.

This method can effectively protect the information you want to send, even if it is intercepted by someone with a heart in the process of information transmission, the other party does not know what is written in it, this method has been circulated as early as the Spring and Autumn Period and the Warring States Period.

And the content of the second silk book before was the unique text created by Chu State himself at that time, Li Zimu thought in his heart while walking, even if Zhang Jingyang went back to find the information, it would definitely not be able to translate it.

The reason why Li Zimu knew that it was a unique character used by the Chu State to record confidential information was because he had carefully studied and compared it at the beginning, not to mention that he could translate all of them, but there was no problem in knowing the general meaning.

And the content of the second silk book, he saw it clearly, it was indeed a paragraph, and he was sure that this was Xiang Yuliu's words:

This is destiny

We can't do it

Now Lone is ordered by Xuanyuan

Take the common people without a word print

With my blood

Seal the altar of a hundred schools

Protect the peace of the people of the world for eternity
