Zhang Yuan really didn’t expect that what Hou Tiannan actually sent him was the Qing Nang Book.

This shock was no less than if the other person suddenly took out a dinosaur and showed it to him, and it was a living dinosaur.

Because according to the history that everyone knows now, the Qing Nang Book has been destroyed and does not exist.

Therefore, the Qing Nang Book is a summary of what the great doctor Hua Tuo learned throughout his life, compiled into a complete book.

Since Hua Tuo often put this book in a green cloth bag, it was finally named Qingnang Book.

Many experts and scholars, including veteran Chinese medicine practitioners, believe that this book definitely records many of Hua Tuo’s medical essences.

Secret recipes such as using Ma Fei San for surgery were just appetizers. It's a pity that this book has not been passed down.

One existing explanation is that when Hua Tuo was treating Cao Cao and needed to perform a craniotomy, Cao Cao became extremely suspicious and thought Hua Tuo was out to assassinate him, so he imprisoned him.

Hua Tuo was unwilling to see his unique skills lost, so he gave the book to the jailer.

After the jailer secretly took the book home, his wife burned it because she was worried that her husband would be caught and killed by Cao Cao like Hua Tuo if he held such a hot potato in his hands.

So they burned the book, and finally only one or two pages were left. The knowledge in the Qing Nang book today is just some minor medical skills about castrating chickens and pigs.

Every time a Chinese medicine practitioner, expert or scholar mentions Hua Tuo's Qing Nang book, they are filled with regret.

When Zhang Yuan learned this knowledge, he also felt regretful...

I have sighed more than once, how great it would be if the Qing Nang Book could have been passed down to the present day?

Does it mean that there is no so-called Western medicine in this world?

Unfortunately, this book was lost after Hua Tuo's death, and no related records of the Qing Nang Book appeared later.

I can only say that it is such a pity.

Who would have thought that what Zhang Yuan never dreamed of was that he would actually be able to see this book in his lifetime, but it appeared in the form of bamboo slips.

Normally, this book should be written on paper. After all, when Hua Tuo wrote this book, he had already started using paper and wrote it on paper.

But the Qing Nang Book in Zhang Yuan's hand is actually a bamboo slip. But it doesn't matter. As long as it is a real Qing Nang Book, no matter what carrier it is recorded in, as long as it is real, it is better than anything else.

Looking at the ancient fonts above, Zhang Yuan felt as if he was in another world!

After a long time, Zhang Yuan looked at Hou Tiannan.

Hou Tiannan didn't say anything, and seemed quite satisfied with Zhang Yuan's series of reactions.

He nodded on the spot, indicating that he wanted Zhang Yuan to open it and take a look. Without saying anything, Zhang Yuan immediately untied the rope of the bamboo slips, slowly unfolded it, and began to read the contents of the bamboo slips.

The bamboo slips were written in small seal script.

For ordinary people, the small seal script is like a heavenly book and is completely incomprehensible. However, Zhang Yuan is an exception. Since he started learning Chinese medicine, Zhang Yuan has been reading various ancient books, many of which are written in the small seal script.

Therefore, Zhang Yuan got used to it and would often look up characters he didn't know. Over time, he accumulated a large number of small seal script vocabulary.

Now, reading this Qing Nang book is naturally effortless and easy to get into. After reading only 20 lines, Zhang Yuan couldn't sit still anymore and said to Hou Tiannan excitedly:

"Mr. Hou, you...you have given me a great gift. This thing is more than just a treasure, it is simply priceless.

There is absolutely no way to measure it with money.

This... this really seems to be the Qing Nang Book. Every word in it is worth a thousand gold."

Hou Tiannan became more and more satisfied with Zhang Yuan's shocked expression.

Because Zhang Yuan's series of emotions are enough to prove that Zhang Yuan is connoisseur and knows how great the significance of this scroll of bamboo slips is.

Hou Tiannan was relieved about this, smiled, looked at Zhang Yuan and said:

"Dr. Zhang, this is just a gift between you and me. This scroll of bamboo slips is only a small part of the first volume of the Qing Nang Book. As you know, the divine doctor Hua Tuo wrote the Qing Nang Book on paper, which contains a lot of content.

What we are using now are bamboo slips, which requires a large number of them to completely record the contents of this book. What you got is just one volume, which can be said to be a very small part of the content.

But you can rest assured, although our Yin Guimen’s other resources are not very abundant, the cultural treasures on this land are indeed very numerous.

If you are interested in the Yongle Encyclopedia, I can also take you to appreciate this lost cultural treasure..."

At this point, Zhang Yuan could no longer sit still. He stood up on the spot and said to Hou Tiannan excitedly:

"Mr. Hou, you...you are simply the noble person in my life. You even have the Yongle Canon. I never thought that the Yin Gui Sect is so powerful.

Aren’t these things already lost? How come the Yin Gui Men have them now? This… How is this possible?”

Hou Tiannan said proudly:

"What do you think the Qing Empire has been doing for hundreds of years? If we can't pass on these things well, it would be too shameful. However, some things can only be passed on to our own people, and some things... even if they are given to Xi Dad for free... they must never be learned by the untouchables of the Galaxy Clan...

The part that cannot be transmitted must naturally be placed in the safest place, and all of it must be searched to ensure that there is no second copy or other version on this land.

In this way, the things we got from the Yin Gui Sect can be called true treasures, and they are unique. "

When Zhang Yuan heard this, he still looked very excited on the surface, but he had already started cursing in his heart.

He even hated the Yin Gui Men so much that he gnashed his teeth and wished he could tear these bastards into pieces and exterminate all nine generations of their clan.

These bastards must be killed one by one!!!

Even Hei Tao, who was standing next to Zhang Yuan, gradually revealed a strong murderous intent in his eyes, as if he hated this kind of thing to the core.

But Hou Tiannan didn't care. Instead, he looked proud and honored.

Zhang Yuan naturally concealed this aspect very well.

He praised Hou Tiannan and Yinguimen on the spot, and pretended to be very yearning.

Hou Tiannan became more and more satisfied. He felt that although Zhang Yuan was very smart and had a high talent for medicine, he did have a weakness after all, which was his extreme obsession with traditional Chinese medicine.

He has even become obsessed to a point of madness. If he can grasp Zhang Yuan's weakness, it will not be difficult to take down Zhang Yuan.

So Hou Tiannan did not try to hide his purpose too much and said to Zhang Yuan directly:

"Doctor Zhang, let's not beat around the bush. Actually, I came to you out of good intentions.

We in the Yin Gui Sect are different from those bastards from the 7th Bureau. If they don't like you, they will try every possible means to kill you.

As for us in the Yin Gui Men, we are much more authentic in the way we behave and do things than them. After all, we all come from this land and are of the same blood. In the final analysis, we are all family members, so there is no need to fight.

It is best if you can get along well with each other.

So, Dr. Zhang, do you understand what I mean now?"
