On the way back, I asked Xiao Lianshan about the origin of Li Zhao and Qingyang, Xiao Lianshan was always vague, and he didn't make it clear for a long time, and he could see that Xiao Lianshan didn't want me and Gu Xiaoxiao to know the identities of Li Zhao and Qingyang.

But I always feel that those two people are not small, especially their age and speech, as well as the agarwood pavilion and the underground treasure house that are like a world away, standing next to them, I always have the illusion of dreaming back to the Tang Dynasty.

I don't know if it was too young before, in my eyes Xiao Lianshan is a competent father, of course, in addition to being stubborn, I can't change him, and he can't control me either, but this time when he came back, I slowly realized that I knew too little about the past of the person in front of me, or I never really knew what kind of experience and story he had.

After I went back, I went to see Yun Duruo, in the past few days, under Gu Anqi's careful care, Yun Duruo seems to have improved a little, at least her face began to slowly have some blood, and the whole person is also a lot more energetic.

"How's your eyes?"

I just sat down next to her, and before I could ask her about her physical condition, Yun Duruo was anxious to ask before me.

"You're all like this, and you're worried about what I'm doing."

I patted her head with a sad smile and said.

"My eyes are fine, you don't have to worry."

Although I said this in my mouth, I knew very well in my heart that after leaving the past few days, my eyes obviously began to blur again, faintly accompanied by some tingling, presumably because I hadn't drunk that medicine in the past few days, but I didn't dare to let Yun Duruo know for fear that she would worry about delaying her body.

Yun Duruo stretched out her hand and shook it in front of my eyes, she clearly didn't believe my words to comfort her, the prince just came back from the temple, and he was still holding the medicine that I had been unknown, Yun Duruo's eyes fell on the medicine in the prince's hand, and he stood up with difficulty and wanted to boil medicine for me, I saw that she was weak like this so that she didn't worry about it anymore, she stubbornly shook her head and walked to the prince's side, I noticed that when she went to get the medicine in the prince's hand, the prince didn't let go for a long time, the two silently pulled back and forth, and the prince wanted to say something with a gloomy expression, But Yun Duruo finally snatched it from him.

I looked at the back of Yun Duruo leaving, and just wanted to pull the prince to ask the truth, Han Yu and Nangong Yi walked in from outside, Nangong Yi held in her hand the Genghis Khan's art of war that we got from Li Zhao, the whole book is written in Mongolian, and only she can understand it.

In order to be foolproof, Nangong Yi copied a copy by hand, and then exhausted all the methods that could be thought of, if Genghis Khan left the clues in this book, he must have used a very obscure method, otherwise although this book of war has been lost, there should have been many people who have read it, and so far someone has found Genghis Khan's mausoleum, indicating that no one has ever understood the secrets in the book.

Nangong Yi said that she had studied the content of the book repeatedly, and from the words in it, it was just a book of the art of war, and there were no strange or clues, but there seemed to be no clue from the text.

Han Yu said that there are many ways for the ancients to pass on secrets, such as writing on paper with white vinegar, and after drying, you can't see anything, and the font will slowly appear when the fire heats up, and then there is writing with alum water, and the font is also invisible but placed in water, and the text on it will appear.

According to Han Yu's train of thought, we carefully and slowly opened the military books, first put them on the fire to warm them one by one, and then put them in water to soak, tossing and turning for most of the night, the whole room was full of pages, but we didn't see a word on it.

"Actually, it's not right to think about it carefully, first of all, if you use this method, whether it is white vinegar or alum water on the military book for a long time, it will volatilize, and those clues will also die out, Genghis Khan can't not take this into account, from the fact that he ordered the eighteen red wolves to secretly leave the grassland with the emperor's tomb, it is not difficult to see, even if he thought that one day someone would open the mausoleum, but it should be a long time later."

Nangong Yi sat on the chair and said calmly.

I nodded thoughtfully, Genghis Khan did everything possible to leave clues, and it was impossible for him not to take these details into account.

"Another point is that it seems too childish to hide secrets in such a simple way, you must know that this is a clue related to a magnificent emperor's mausoleum, if Genghis Khan really left clues in this way, wouldn't he have been worried that someone would accidentally discover the secret in the book for hundreds of years......"

"We're looking for clues in the wrong direction right now."

The prince sat on the side and said with a heart like water.

"Wrong?"

I looked at the prince and asked suspiciously.

"What's wrong?"

"What are you doing here?"

Gu Anqi and Xiao Lianshan walked in from outside, looked at the pages of the room and asked in surprise.

"We are looking for clues left by Genghis Khan in the book of soldiers."

Gu Xiaoxiao replied with a serious face.

"You're looking for clues like this?"

Gu Anqi looked around with a smile and a smile.

"Even if Genghis Khan left the clues of the imperial tomb in the book of the art of war, how can you be sure that the one with the clues is the book of war in your hands?"

I was stunned and stood in place for a moment, and the others also understood, it seems that the room full of people are too obsessed, only the prince is clear, Li Zhao only said that the military book to us is a lone book, but presumably there should be other such military books, we don't know which one the clues are left in.

"With a brain like yours, you still want to find Genghis Khan's Mausoleum."

Xiao Lianshan looked at Gu Xiaoxiao with a wry smile on his face, sat aside and said lightly.

"Judging from the clues we have obtained so far, nothing has ever pointed to the book of war, and if Genghis Khan really left the clues in the art of war, there must be a crucial original."

"Another thing you haven't thought about is that if Genghis Khan left the clues in the art of war, it means that whoever gets the book will be able to see the secrets."

Gu Anqi said to us very calmly.

"But no one has found Genghis Khan's mausoleum in the past few hundred years, either the original record of the secret has been lost, or no one has learned the mystery, Genghis Khan is a general, you can think of it when he leaves clues, he will also think of the consequences of the original loss."

"Then it's a big trouble, that is, the military book we have now is useless."

Gu Xiaoxiao pouted and said disappointedly.

"Hey...... You stupid girl, why don't you understand, the clue is indeed in the book of war, but it is not what you thought before, the clue is actually in the text of this art of war. ”

Gu Anqi smiled helplessly at Gu Xiaoxiao.

"Only in this way is the most appropriate way to pass on secrets, and those who can't find the trick will be at a loss even if they get the war book, and the secret of Genghis Khan's tomb is in these words."

"Aunt Gu, I have studied the contents of the military book repeatedly, but I didn't find anything between the lines."

Nangong Yi said seriously.

"It's so easy for you to know, and then it can be called a secret?"

Gu Anqi replied with an amiable smile.

Yun Duruo happened to come in from outside with medicine, she should be afraid of dripping a bowl full of medicine, she was careful with every step, her eyes were focused on the medicine bowl in her hand, and when she came in, she didn't notice that her feet were full of pages, and she stepped on it Han Yu was shocked to remind.

Yun Duruo's hands trembled in shock, and the medicine in the bowl dripped on the pages, and Yun Duruo subconsciously withdrew his feet, because the pages on the ground were soaked in water, and they were damaged with a little force.

I hurriedly walked over and took the medicine bowl from Yun Duruo's hand, Han Yu and the prince squatted on the ground and picked up the pages that were trampled on by Yun Duruo, the words on it were blurred and could not be restored.

"I'm sorry, I didn't see that."

Yun Duruo said apologetically knowing that the matter was important.

"It's okay, Nangong Yi is worried that there will be a mistake and a copy of it was copied in advance, and the damaged text can be recovered by comparing it."

I pulled Yun Duruo to sit down and said with relief.

Yun Duruo breathed a sigh of relief, compared to the priceless art of war, she seemed to be more concerned about my eye disease, urging me to drink the medicine quickly, I picked up the medicine and suddenly found that Yun Duruo's spirit had just improved and became sluggish, and his face was as pale as white paper, I just wanted to say what she couldn't help but push the bowl to my mouth, I said that the bowl of unpalatable medicine drank in one gulp.

"How to say that this is also Genghis Khan's art of war, it has been lost for so many years, and now it has regained its value, its value is immeasurable, and it would be a sin if it was destroyed in our hands."

The prince said as he looked at Nangong Yi.

"Compare the one you copied to see what the damaged words are, I marked it next to it and waited for the pages to dry and then rebind it, this is a precious artifact."

Nangong Yi nodded and asked Han Yu to help compare the original and transcribed texts.

"Page 3, descending fifteenth word."

Han Yu said while checking carefully.

"On the third page, the fifteenth word down is ......"

Nangong Yi looked at the transcribed art of war and said.

"It's hoarding, and the whole sentence is besieging the city and hoarding troops to focus on food......"

…… I had just finished drinking the bowl of medicine, and suddenly I stood in place in a daze, repeating the words that Han Yu had just said.

Page 3, descending fifteenth word...... Everyone's eyes were looking at me, probably not understanding why I suddenly reacted so much, I put down the bowl and walked to the table, picked up the transcribed military book, although I couldn't read the Mongolian on it, but I counted the words and pages on it, Li Zhao gave us each page of the military book is numbered, and my eyes suddenly lit up when I turned to the last page.

The map of the human skin tattoos left by Yoshida Hanzo is made up of the chest tattoos of the descendants of the eighteen red wolves, and there are two numbers under each tattoo, and we still don't know what the numbers are used for.

"What is the largest number on a human skin tattoo?"

I asked hurriedly.

The crown prince and Han Yu hurriedly unfolded the map of the human skin tattoo and gave a definite answer after taking a look.

"Seventy-five."
