After Chu Nan and Wu Bei discussed Tang Yarou's affairs, they returned to the room alone and began to study the "Gu Poison Sutra", Chu Nan has been learning various skills with the old man since he was a child, medical skills and kung fu are the two most proficient in learning, the old man once said that medicine is to cure diseases and save people, but martial arts is to kill people, whether it is killing people or saving people, if it is used properly, it is all for the benefit of society.

Chu Nan felt that the old man's words were very right, so although the old man claimed to be proficient in astronomy, geography and medicine, Chu Nan only devoted himself to the two aspects of martial arts and medicine, of course, the old man also handed over all other things to Chu Nan, according to Chu Nan's qualifications, even if he did not study hard, but the level was not low.

This "Gu Poison Sutra" has never been learned from the old man, because at that time was in the cottage at that time, Chu Nan did not have time to study it seriously, so he could only go through the "Gu Poison Sutra" to find out how to remove the Gu poison on the cottage people and Aunt Liu Chunfang, and now he looked at it seriously from the beginning, the more Chu Nan looked at it, the more frightened he became, the content in this "Gu Poison Sutra" was extremely magical and profound, according to the Gu poison applied by Mrs. Snake Ji, she only learned the realm of Xiaocheng, It's still a lot away from the Dacheng realm.

And Chu Nan inadvertently turned the book to the last one, but saw that someone actually wrote on it with a pen on the last page: "Miao Jiang is known as the holy land of Gu poison, the locals call Gu science witchcraft, and the witchcraft performed by the wizard is for Gu poison, the old man went to the Gu clan in Miao Jiang to challenge the Gu poison master, and killed all the well-known wizards, although he did not meet the opponent, but he deeply felt the mystery of Gu poison, so he spent three years and three nights in retreat, and finally integrated Gu science, improved it, and wrote the book "Gu Poison True Scripture", and those who were destined to get it. When you learn the realm of Xiaocheng, you can slaughter a city in anger, and when you learn the realm of Dacheng, you can slaughter a country in anger, and you can integrate this book, and you can be called the king of Gu poison. Because the Gu poison theory is that the old man traveled all over the land of Miao Jiang to learn Gu poison, and finally used it, and it should be given to people when it is taken from people, so the old man hid this book somewhere in Miao Jiang, and those who are destined to get it. ”

And what surprised Chu Nan the most was that the name of this person's message was called the Poison King.

Unexpectedly, what this Lady Snake Queen got was the secret book written by the Poison King, and finally fell into her own hands, if the old man is really the King of Medicine, then this doctrine is not written by the old man's sworn enemy?

The last time I returned to the mountain, I didn't meet the old man, maybe the old man went down the mountain, and the mobile phone should not be charged, so Chu Nan called the old man again, and I didn't think that there was still no one to answer there, but Chu Nan was not worried, according to the old man's strength, before he went down the mountain, he was only abused by the old man, even if he had reached the king realm now, but Chu Nan was not sure that his strength must be above the old man.

Chu Nan originally saw that this book was written by the Poison King, and thought that the Poison King might be the old man's opponent, and he didn't want to learn what the old man's old enemy wrote, but the old man's phone was really unreachable for a while, such a subtle book was placed in front of his eyes, and he couldn't help but read it, and finally Chu Nan couldn't help it, and finally couldn't help it, water can carry a boat and overturn a boat, kung fu can kill people, and it can also save people, isn't the same true of the so-called Gu poison theory? If he hadn't found the answer in the "Gu Poison True Scripture", the more than 15,000 people in the entire Jiuyang Cottage would have turned into white bones, and the stepmother would have died.

Chu Nan looked at it, and it was completely difficult to extricate himself, poison and medicine are often separated by a thin line, the old man once taught Chu Nan that medicine can save people and kill people, but most of what the old man taught Chu Nan is the art of saving people, and what this "Gu Poison Sutra" talks about is the art of killing, and all of them are killing people with Gu worms.

Gu poison is a very magical poisonology, after the sorting and research of this poison king, this "Gu Poison True Scripture" has almost refined the essence of the entire Gu science, and even improved it, it is better than the Gu science of the Miao Jiang Gu clan, I have to say that this poison king is a rare genius in a thousand years in terms of poison, and many of the ideas are not in the original Gu clan, which makes people feel unbelievable when they hear it.

Chu Nan saw that it was at night, and it wasn't until someone knocked on the door at night that Chu Nan came back to his senses, put away the Gu Poison Sutra, let out a long breath, and his eyes were full of brilliance, Chu Nan felt that Tong Guò's "Gu Poison Sutra" was about to make a breakthrough in his own medical aspects.

Medicine and toxicology itself are in the same line, which is the same as what the old man said that medicine can kill people and save people, and toxicology also contains a lot of medical truths, for example, the Gu poison chapter talks about how to use Gu poison to kill people, and the Gu solution chapter is written about various ways to remove Gu poison, in the study, Chu Nan also has a little more understanding in medicine, and feels that his strength is further improved.

Of course, Chu Nan didn't dare to say that he had been able to reach the realm of the Holy Hand of Medicine, but when he was watching this book, Chu Nan found that Gu poison was to use a kind of Gu insect to harm people, but couldn't Gu insects save people? Chu Nan had a feeling that Gu poison could also be used in medicine, and if he could study this method of saving people, presumably Chu Nan would soon be able to enter the realm of the Holy Hand of Medicine.

As long as he thought about it, Chu Nan felt a little excited, it was not that Chu Nan cared about a false name, but a kind of stubbornness, the same as treating martial arts, and in treating medicine, Chu Nan also had a kind of stubbornness, otherwise, just with his amazing talent, how could Chu Nan achieve this kind of unprecedented Cheng dù in medicine and martial arts at the same time?

In the history of China, the youngest king intermediate and the youngest medical master, it can be said that Chu Nan has set a record in two fields!

After Chu Nan had dinner, he returned to the room alone, and the whole person was immersed in the mystery of "Gu Poison Sutra", and in the next few days, Chu Nan even hid in the room by himself when he even ate, Hu Niu personally sent the meal in, and immersed himself in this "Gu Poison Sutra", and Hua Linglong and Wu Bei did not bother Chu Nan, and Wu Bei's negotiations with Tang Yarou also went very smoothly, because of Chu Nan, Wu Bei gave Tang Yarou a lot of preferential treatment, You can sign the contract directly.

Five days later, Yin Zhaotian checked the pulse of an old man and prescribed medicine to him, the old man stood up and turned around to leave with a thousand thanks, Yin Zhaotian just asked Hu Niu to call the next patient over, but saw Chu Nan finally come out of it.

"Master." Yin Zhaotian stood up, looking at Chu Nan with blazing eyes, with a look of surprise, I don't know why, Yin Zhaotian felt an indescribable temperament on Chu Nan's body.

Chu Nan smiled and said, "What's wrong?" ”

"Master, I feel that your temperament seems to be different from before."

"Yes." Chu Nan smiled and said, "I've had a lot of gains in the past few days, go to my room when I'm done, and I'll tell you." ”

Yin Zhaotian's eyes lit up, Chu Nan is now at the level of a medical grandmaster, and he can make Chu Nan feel a great harvest, it can be seen that Chu Nan must have gained a lot in the past two days, and Yin Zhaotian will benefit immensely after listening to it.

Yin Zhaotian hurriedly agreed, in the medical hall, it is usually extremely difficult to treat diseases before they are handed over to Yin Zhaotian, some small problems will be treated by Hu Niu and Wang Yue personally, Hu Niu has followed her father to see the neighbors since she was a child, there is no problem with the usual small problems, Wang Yue graduated from medical school after all, after such a long time of training, although the level is not up to Hu Niu's Cheng dù, but the common cold and fever are still no problem.

After solving the two most difficult patients, Yin Zhaotian came to Chu Nan's room, and when he saw Yin Zhaotian coming in, Chu Nan smiled and said, "Zhaotian, come in." ”

"Master......."

"Well, in fact, I haven't taught you much in the past, and I still feel guilty when I hear you call me a master."

Yin Zhaotian was about to sit down, and after listening to Chu Nan's words, he suddenly showed a stern look on his face, and said: "Master, since I lost to you in the Northern Medical Competition, you are the person I admire the most, I am willing to be your apprentice, there is absolutely no reluctance, master should not say this again in the future." ”

"Haha, I know, sit down quickly, it's because I feel ashamed that I'm going to teach you some good things myself. Have you ever heard of Gu poison? ”

"Gu poison?" Yin Zhaotian said with a surprised face, "I've heard that it is an extremely vicious method, it is rumored to be a kind of witchcraft of the Miao Jiang Gu Clan, only extremely powerful wizards will use it, in fact, it is just a kind of poison art." ”

Chu Nan nodded and said: "You are right, but this poison is much more vicious than most poisons, it can be fatal, but it can also control a person or even a group of people." ”

"This time I went to Jiuyang Cottage, the biggest gain was that I came into contact with Gu poison, and when I came back, I studied it and learned a lot from it."

Yin Zhaotian hesitated slightly, opened his mouth, and stopped talking, but he couldn't say it after all.

Chu Nan knew what Yin Zhaotian wanted to say, and said with a smile: "Do you want to say that this is a vicious poison technique, and we medical students should not come into contact with it?" ”

Yin Zhaotian nodded.

Chu Nan laughed and said: "Actually, I also hesitated at the beginning, and I had the same idea as you, but the old man of my family also told me in the past that toxicology and medicine are actually in the same line, and there are many connections between them, and we can learn from each other." For example, in medicine, there is still a saying that poison fights poison, isn't it? After thinking about this, I began to study behind closed doors in the past few days, how to study the method of curing diseases and saving people from Gu science, and the results were really researched by me, so I can share it with you. ”

Chu Nan has indeed learned a lot from the "Gu Poison True Scripture" in the past few days, and the most important thing is that Chu Nan can slowly transform some of the theories about poison into medicine, if the old man sees this, he will definitely be very pleased.
