Li Huaiyun flipped through the medical book from beginning to end and forcibly wrote down the contents, but there was a lot of content, and he could only remember the next approximation, and some details were easy to forget.

He felt that this was inappropriate, this was a medical skill, and the most taboo thing in practicing medicine was this kind of half-understanding, and if there were no details, it would be easy to heal people to death.

Never mind! Li Huaiyun flipped through the Qingbao Neijing from the beginning, striving to write down the contents in the most complete way.

Don't force me to remember everything, but be sure to remember the details!

Before that, he had copied half of the book in the arsenal of the Demon Slaying Division, and now, he probably remembered about half of the content of the Inner Scripture of the Green Sac.

Although this is a fragmentary medical book, it records medical skills, herbal medicine, finding tendons and pulses, and practicing medicine and healing, ranging from red rashes on the body to serious diseases.

However, there is another part of the book about the mystery of the human body, how to unleash the potential in the body in a natural way.

Among them, there is the method taught by Hong Yun, which pierces the acupoints of the head with silver needles to fully release the potential of the body.

Li Huaiyun was very puzzled by this, my aunt had read this medical book before! Wait a minute, didn't you say that this medical book has been missing for a long time? Judging from my aunt's age, could it be that she saw it when she was very young?

He suddenly suspected that Hongyun had an extraordinary relationship with this medical saint!

He continued to scroll down, and suddenly realized that the next few pages were a little unusual.

The words written on those pages were slightly different from the previous ones, undulating, and very small holes, and what made me feel even more strange was that the material of those pages was quite rough to the touch.

He picked up the medical book and put it in front of his eyes, and the clear pore lines on it jumped in front of him, and in an instant, this scene made him frightened and speechless for a while.

Human skin!

Li Huaiyun subconsciously took the medical book away, this thing looks quite scary, why should a good medical book be made of human skin in it?

Could it be that what kind of trickery is recorded above?

He hurriedly placed the medical book in front of him, carefully scereging the words on it, which were not clear because they were written on human skin.

As he expected, the human skin was recorded with a special exercise, and due to the passage of time, the text had faded slightly.

After his simple identification, it was a strange exercise, which was to put oneself into a state of death, and then turn into a pupa body!

Is this playing dead and then feathering into an immortal? I didn't say what would happen after pupation?

Li Huaiyun looked puzzled, but he still kept this exercise in his mind and prepared to find a time to practice.

This exercise, it looks very strange, maybe it will have a miraculous effect, just like that theory of perception, the transformation of one's own reproductive impulse into essence, stored in the dantian, maybe this exercise will have some inexplicable effect.

Li Huaiyun took a while to learn this exercise, and then memorized some other content.

After he finished this, he thought to himself, I now have the silver needle given by my aunt on my body, and I also have the practice of turning a chrysalis into a body, all of which are life-saving.

He faintly felt a little uneasy, and had a premonition that something big would happen to him!

Shouldn't you use it all? If you don't save your life after using it, then it won't be very embarrassing to go down to the underworld!

Li Huaiyun fell into deep thought, and after a while, from not far away, there was the sound of conversation and footsteps.

The voice pulled him back in thought, and he immediately put the medical book back in its place, back to its previous position.

In addition to the voice of the wooden kite, there was another voice that sounded very anxious, and his voice trembled a little.

"Princess, the record of the construction of the sewer has always been there, and no one has touched it! Could you have not looked carefully? ”

The kite responded, "We searched all the books in our cabinet, but we couldn't find them!" ”

"Impossible!"

As the footsteps approached, Li Huaiyun stood in front of the cabinet and saw a middle-aged man in an official robe walking over with the wooden kite.

The kite pointed to where he stood, "Right there, you go up and help me find it!" ”

The official looked flustered, hurriedly walked up, and began to search for the cabinet, muttering, "Impossible! No way! ”

Li Huaiyun stood aside, clasping his hands in front of his chest, "This is the one who manages the library pavilion?" ”

"Hmmm! He has been in charge of it all these years, except for the historian, basically no one else has been here, if it is known, the books inside are lost, he may lose his head! ”

"No wonder you're so nervous!" Li Huaiyun said, "It's a pity that there is no monitoring!" ”

"No surveillance?" The wooden kite asked, "What do you mean?" ”

"Huh!" Li Huaiyun's mind turned quickly, and he wanted to explain it in the simplest language, "It's probably to record a certain location, who has come." ”

"It's like identifying by smell!"

"That's pretty much it."

The official was sweating coldly on his forehead and his back was already wet, and he stood in front of the cabinet, folded his hands, and bowed to the bookcase, as if asking God to worship Buddha.

However, despite his piety, it was of little use, and he did not find any record of the construction of sewers on the cupboard.

He became more and more anxious in his heart, after working here for so many years, it was the first time such a thing had happened, and if someone played, he would be held accountable for dereliction of duty.

This is a capital offense! With a desperate look on his face, he leaned against the cabinet, folded his hands again, and then carefully rummaged through the construction records.

Li Huaiyun scratched his head, seeing the official's anxious look, he also pinched the sweat for the official, "Or, let's help find it too?" ”

"That's fine!"

"What happens if I can't find it?"

The wooden kite thought for a while, "If you are exiled, if you are heavy, you will be beheaded!" ”

"So serious?"

"That's because I lost something, and I don't know if some of the secret things in the library will be leaked, so it's such a felony."

"Sure enough, when you are doing things in the palace, there is a danger that your head will fall to the ground at any time."

Li Huaiyun and Mu Kite were also looking for the nearby bookshelves, and he found the books in another cabinet, but he did not tell them immediately.

Instead, he went to the inner meridian of the green sac to further consolidate the contents, and after being questioned by the wooden kite, he put down the inner scripture, and then walked up and pointed out the location of several books built by the sewer.

The official saw these long-lost books, and the whole person was excited to tears, he folded his hands together, and kept bending down to Li Huaiyun to thank him, this is his reborn parents, in case, no one finds out, I am afraid that his life will not be saved.

Li Huaiyun saw that the man was still thanking him, and hurriedly raised his hand, "Okay!" It doesn't make sense to thank you more, it's better to let us know in time when we have problems. ”

The official hurriedly nodded in agreement, "No problem! No problem! ”

"Why are these books here?" The wooden kite had some doubts about this.

"Maybe someone read it and put it away!"

Li Huaiyun has a different opinion on this, the height of those books needs to be bent, which makes people very suspicious.

This is obviously deliberately put down by someone, and it is blocked by other books, and someone already knows one step in advance! In order not to reveal his identity, he just hid it somewhere else.

Li Huaiyun and Mu Kite took the sewer construction record book and began to flip through it, and the reason and process were relatively simple.

The Imperial Palace was built on a treasure of feng shui in Kyoto, but the land is in a low-lying area, and there is always standing water during the rainy season and other rainy days.

Therefore, it was proposed that a sewer should be dug up to drain the palace during the renovation of the palace.

Only then did the construction of the sewers begin.

There were also a few summaries of the construction of the sewers, as well as records of the construction payments, but they looked through them and found no useful information.

Li Huaiyun quickly checked the construction records, from feng shui positioning, day selection, to design, excavation, page by page of clear records, however, there are also many days missing without remembering, the reason is unknown.

He sighed, "Looks pretty normal!" ”

"yes!" The kite responded, "It seems to be going well." ”

"In this regard, it is still necessary to find people who understand some knowledge, and maybe they can find the problems better."

"Does Si Zheng understand this?" Li Huaiyun asked!

"Old man Qin knows a little, but he's very busy these days!"

Li Huaiyun asked with a little curiosity, "What are you busy with?" "Is there anything more important than the things in the palace?

"Then I don't know!"

Li Huai looked at the official, "Do you understand?" ”

The official bowed his head, "The little ones don't understand architecture. ”

Li Huaiyun went through the historical materials and records of the construction again, and if he couldn't find any more problems, he could only bring them out and let a special person check them.

Suddenly, he noticed a strange thing, which was recorded for some days when it had not been built, and during this time, it was clear that there was a stoppage in it.

According to the above date, he checked the payment for the project and the purchase of materials, and found that during that time, a large number of construction materials had been used, indicating that there must be a rush somewhere.

Li Huaiyun looked at the official again, "Do you know these construction materials?" ”

"I don't understand architecture, but I've read a lot of books in it, so I know a little bit about many things in the palace. ，”

"That's good! You can help me see how to explain this matter! ”

Li Huaiyun flipped through the construction record, and then handed over the record, "It took more than two years from the beginning of construction to the completion of construction here,"

"During this period, it was about a month or so, and it was not recorded until the completion of the project."

He frowned, "But you can see that in the purchase of project money and materials, there were more purchases in those days, and the price was much higher than before, so it can be seen that this has been built, but it has always been a large purchase of materials." ”

The official took the book, looked through it carefully, and thought to himself, "I roughly understand what this means!" ”

"What do you mean?"

"When the sewer was being built, there were several accidents, deaths, and landslides, so it's the record you see now!" ，

"Ahh It turned out that this was the case, and after that, the matter was settled, and the sewer was continued. ”

The official nodded slightly, and said softly, "The construction of this sewer is quite difficult, from the beginning of the rock wall geology, the construction period was delayed, and later, the construction of the sewer encountered a serious problem, which almost directly led to the fact that this project was almost yellow!" ”

Li Huaiyun asked, "I want to know what happened to the suspension of construction after such a serious problem!" ”

The wooden kite blinked her translucent eyes, "Isn't that the collapse you are talking about, the dead man's thing?" It may be that the internal foundation is unstable! ”

Li Huaiyun shook his head gently, "At first, I thought it was, but looking at the purchased materials, basically all of them have been changed, and those who are tired and die suddenly are also very strange, this construction project is not in a hurry." ”

"This is no longer a normal situation, the whole project has been directly interrupted!"
