Zhang Zhenzhong shook his head and said, "Do you think that the ancestors are not as smart as you? They also want to think of it, and in the end, it is not a matter of dissipating merit and returning to ordinary." ”

"Dad, aren't you looking forward to the day when I will also return to the mortal world? I have just started my cultivation, and I am looking forward to my dissipation. Zhang Hanlin pouted.

"I ......" Zhang Zhenzhong had nothing to say, when he first gave Zhang Hanlin this [Yin and Yang Jue] exercise, Zhang Zhenzhong really thought so.

However, with the experience of deceiving Zhang Hanlin last time, Zhang Zhenzhong specially knocked on the side this time, which can be regarded as a reminder that he will not be able to find him if there is any problem in the future.

Who would have thought that Zhang Hanlin would discover the secret of the [Yin and Yang Formula] so early.

Zhang Hanlin continued: "I haven't practiced martial arts in these years, and I am too far behind my peers, although the [Yin Yang Jue] has its drawbacks, but I feel that its cultivation speed is indeed shocking and extraordinary, I have an intuition that if you want to practice martial arts successfully, this [Yin Yang Jue] is probably the best choice." ”

"It's not a small ambition. Zhang Zhenzhong did not hesitate to strike.

Seeing that Zhang Hanlin wanted to compete with Zhang Zhenzhong, Zhang Tianhong came out to play a round and said, "Okay, you all talk less." Your father and I didn't know much when Hanlin was practicing martial arts, if you have any doubts during this time, you can ask Bai Shen for advice, and he will not hesitate to say anything. ”

"Grandpa, I see. Zhang Hanlin smiled and nodded, then glared at Zhang Zhenzhong, hitting himself all day long.

"Grandpa, after I go to Baifu tomorrow, I will explain this matter to my uncle, so that he can also have a mental preparation. ”

"Well, it is indeed necessary to tell Bai Shen about this matter, tomorrow you will tell Bai Shen in detail about this matter, if he has any ideas, you can discuss it with him. Zhang Tianhong thought about it for a moment and nodded in response.

"Yes, I will. ”

Subsequently, Zhang Zhenzhong and Zhang Tianhong left the medicine pavilion, and Zhang Zhenzhong took away the silver paper wrapped in poison powder.

The medicine cabinet is divided into a library cabinet, a pharmacy, and a pharmacy cabinet.

Zhang Hanlin left the secret room in the pharmaceutical pavilion and came to the library pavilion.

The books in the library are piled up as high as a mountain, and there are tens of thousands of books in the huge library cabinet.

There are many bookcases on the four sides of the south, east, west, and north, with as many as five layers, and the books are arranged in a detailed and orderly manner.

In the bookcase on the east side is the classic medical books written by the ancestors of the Zhang family, with nearly 2,000 ancient books, from top to bottom, the medical works of each ancestor are arranged in chronological order.

The bookcase on the west side contains classic medical books other than the classics written by the ancestors of the Zhang family, arranged according to different aspects such as internal injuries, external injuries, medical treatment, acupuncture and moxibustion.

The bookcase on the south side is 5,000 yuan, which is almost all the ancient books in the history of the Beichen Continent, among which the Beichen literati Da Confucian, the historian of the Great Interior, compiled about 4,000 classic books.

And the literary works of several other countries, ancient books

, which adds up to less than a thousand.

In the bookcase on the north side is the classic book that Zhang Hanlin needs to study tonight, the book of poison and medicine, which contains less than 100 books, but each poison scripture is famous, and behind each poison scripture is a terrible and tragic story.

Although the Zhang family doctor and the holy family will not be contaminated with this kind of poison that violates the principles of heaven, but the extreme of things must be reversed, otherwise the extreme Tailai comes, and there are two sides to everything.

Since ancient times, there have been rumors that medicine is poisonous, and this is not a rumor, but a truth that has been summed up after hundreds of years of painstaking research by countless people thousands of years ago.

Therefore, when Zhang Hanlin was studying medicine since he was a child, he kept in mind the ancestral teachings of the Zhang family, and when prescribing prescriptions, he could not only focus on the symptoms and rush to prescribe medicine. Instead, it should be considered in all aspects, such as the medicinal properties of the herbs, the detailed condition of the patient, and the side effects of the prescription, and many other factors should be taken into account, so as to minimize the side effects of the prescription, that is, to remove the toxicity in it.

As Zhang Hanlin said, things are dead and people are alive. The point is that if the person who clings to things is in the hands of the wicked, the poison will show a harmful side. If it is in the hands of a good person, such as a poison in the hands of a doctor, it can also become a cure.

Therefore, the Zhang family also included the most famous poison scriptures in the mainland, and the knowledge written in them was of great benefit to people in the medical Tao.

However, Zhang Hanlin was very uninterested in the poisonous scriptures in the medicine pavilion a few years ago, so he never liked or wanted to study them.

Today, I had to watch it, and Zhang Hanlin also figured it out, how could there be so many people who were willing or not, since they needed it, they would learn it.

Coming to the bookcase on the north side, Zhang Hanlin stepped on a high stool, looked at the name of the Poison Sutra with a candle, and finally selected ten copies.

Then he took ten poisonous books to a desk in the library cabinet, put the candle on the table, and began to flip through the books.

The first book is the earliest book of poison since the record, and the title of the book is "Chiyou Poison Sutra".

In the Great War of Antiquity, the Yellow Emperor defeated Chiyou and took over everything in the Chiyou tribe, including the "Chiyou Poison Sutra".

This scripture is known as the four major medical scriptures of the Tianyuan Continent together with the "Yellow Emperor's Neijing", "Bian Que's Neijing" and "Huatuo Medical Scripture".

"Chi You conquered the world, and took all things in the world, loved poisonous things, practiced magic skills, supplemented by poison, and achieved great magic skills, and the poisonous fog was filled with a wave of his hand, shrouding thousands of miles.

However, the amount of poisonous mist required to cultivate demonic skills is beyond imagination, so Chi You compiled a poison scripture, with an introduction to the shape of the poisonous mist and toxicity, and handed it over to his subordinates to collect everywhere in the world.

After the defeat of Chiyou, this poison scripture fell into the hands of the Yellow Emperor, and the Yellow Emperor did not destroy it after reading it, but ordered someone to sort it out, annotate, fill in, and finally make it into a book, which is now circulating in the world "Chiyou Poison Sutra". ”

Zhang Hanlin looked at it through the candlelight, and the "Chiyou Poison Sutra" recorded various poisons in ancient times, and the first one in the first row was the queen bee needle, which stinged people with severe pain

After poisoning, the whole body is swollen, the blood is stagnant, and the poison can flow along the blood throughout the body in a moment, and within a quarter of an hour, the poisoned person will die of poison. However, the venom stored in the queen bee needle has an anesthetic effect, and it can be extracted, mixed with other medicinal materials, and boiled through many cumbersome processes to make anesthetics.

This is much more advanced than the Ma Boiling Powder researched by the medical saint Hua Tuo.

However, the queen bee is extremely rare, not to mention the queen bee needle that is regarded by the queen bee as her own life, so this kind of queen bee poison is unavoidable, it is precious, and it is a rare item with no price in the Tian Yuan Continent.

The second is the ghost king grass, one leaf and four forks, the leaves are purple, no peculiar smell, and the appearance is beautiful and attractive.

However, the ghost king grass is highly corrosive, the skin is injured when touched, and the toxicity goes straight into the heart along the wound, inhibits the heartbeat, and eventually leads to death.

The third green spirit snake, sharp teeth, contains strong poison, has strong coagulability, poisoned people blood coagulated all over the body, unable to breathe, the whole body stiffened, suffered severe pain and died.

Because this snake venom is the strongest one in the world, the poison erupts quickly, and the poison can spread throughout the body in a few breaths, and the antidote that can relieve this toxicity has not yet been developed, and even if it is developed, there is no time to take the medicine at all, so there is no cure for Qingling snake venom at present.

Fifth...

Sixth...

...

"Chi You Neijing" has a physical picture attached to the left side of the poison, and the introduction is very detailed, which is still very novel for Zhang Hanlin, who saw these for the first time.

Time quickly passed an hour, Zhang Hanlin at a glance and ten lines, never forget, just after an hour, nearly 50 pages of "Chiyou Neijing" read through and memorized by heart.

The books in the "Chi You Neijing" are all hundreds of strange poisons in the world, all of which are audible, and with the changes of the times, many poisons are also extinct, perhaps only some medical saint families, or the Chinese side of the Imperial Medical Palace can get one or two of them, and although the Zhang family is also a medical saint family, the Zhang family adheres to the admonition of Zhang Ji's ancestors, benefits the dawn, and carries forward the medical Tao.

Therefore, for these rare treasures in the world, such as rare medicines and rare poisons, the Zhang family, as a medical saint, is not committed to this, but is good at developing Zhangjia pharmacy to benefit the people and save people.

Putting down the "Chiyou Neijing", Zhang Hanlin rested for a while, and then continued to study the next poison scripture.

"Little Golden Poison Sutra", is known as the little doctor saint Jin Qing compiled a poison scripture hundreds of years ago, some relatively rare, and toxic poisons recorded in it, as a kind of supplementary introduction to the world's poison scripture, although more partial, but "Little Golden Poison Sutra" is also very famous.
