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 learned various abilities from 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 to kill people or save people properly, it will benefit society.

Chu Nan felt that the old man was right, so although the old man claimed to be proficient in astronomy, geography, medicine, divination, Chu Nan only focused on studying both martial arts and medicine. Of course, the old man also gave all other things to Chu Nan. According to Chu Nan's qualifications, even if he did not study hard, his level was not low.

This book of "Gu Poisonous Sutra" was never learned by the old man. Because the time was urgent in the village at that time, Chu Nan had no time to study it carefully. He could only find out how to remove the Gu Poisonous poison from the people of the village and Aunt Liu Chunfang through the "Gu Poisonous Sutra". Now, when he read it carefully from the beginning, Chu Nan became more and more shocked the more he read it. The content in the "Gu Poisonous Sutra" is extremely magical and profound. According to the Gu Poisonous poison exerted by Mrs. Snake Ji, she only learned the realm of small success, which is still much worse than the realm of big success.

Chu Nan accidentally turned the book to the last article, but saw someone in the last page that wrote on it: "Miaojiang is known as the holy land of Gu Poison. The locals call Gu Learning a witchcraft. The witchcraft used by wizards is Gu Poison. I went to the Miaojiang Gu tribe to challenge Gu Poison masters and killed all the well-known wizards. Although I had not encountered an enemy, I felt the mystery of Gu Poison. So I went to the Miaojiang Gu Tribe to challenge Gu Poison. I was very proud of Gu Poison. So I went to the Miaojiang Gu Tribe to challenge Gu Poison. I killed all the famous wizards. Although I had not encountered an enemy, I felt the mystery of Gu Poison. So I went into seclusion for three years and three nights and finally integrated Gu Learning a wizard.

If you are proficient in writing the book "The True Sutra of Gu Poison", those who are destined to get it. If you learn the state of small success, you can slaughter a city with anger, and you can slaughter a country with anger. You can integrate this book into one, and you can call it the king of Gu Poison. Because the theory of Gu Poison is that I traveled all over Miaojiang and learned Gu Poison, and finally used it, and it should be taught to others. Therefore, I have hidden this book in a certain place in Miaojiang, and those who are destined to get it."

What surprised Chu Nan the most was that the name of the person’s message was called the Poison King.

Unexpectedly, what Mrs. Snake Ji got was a secret book written by the Poison King, and finally fell into her own hands. If the old man was really the King of Medicine, then wouldn’t this theory be written by the old man’s mortal enemy?

The last time he returned to the mountain, he did not meet the old man. Maybe the old man went down the mountain, and his phone probably was not charged. So Chu Nan called the old man again and didn't expect that no one would answer the answer there. However, Chu Nan was not worried. According to the old man's strength, he was only abused by the old man before going down the mountain. Even though he had reached the king level now, Chu Nan was not sure that his strength must be above the old man.

Chu Nan originally saw that the book was written by the Poison King. He thought that the Poison King might be the old man's opponent and did not want to learn what the old man's old enemy wrote, but the old man's phone number was really unreachable for a while. Such a wonderful book was placed in front of him. He couldn't help but not read it. Finally, Chu Nan couldn't help but read it. Water could carry a boat and could overturn it. Kung Fu could kill people and save people. Isn't the so-called theory of poison? If he hadn't found the answer in the "Gu Poison True Sutra", the more than 15,000 people in the entire Jiuyang Mountain Village would have turned into bones, and Lingling's stepmother would have died.

When Chu Nan saw it, it was completely difficult to extricate himself. Poison and doctors were often separated from each other. The old man once taught Chu Nan that doctors can save people and kill people, but most of the old man taught Chu Nan was the technique of saving people. The "Gu Poison Sutra" talked about killing people, and all of them were killing people with poisonous insects.

Gu poison is a very magical poison. After the compilation and research of this poison king, this book "Gu Poison Sutra" has almost refined all the essence of the entire Gu science, and even improved it, which is better than the Gu science of the Gu tribe in Miaojiang. It has to be said that this poison king is a rare genius in poison science, and many of its ideas are not originally in the Gu tribe, which makes people feel incredible.

Chu Nan saw it at night, and it was not until someone knocked on the door at night that Chu Nan came to his senses, put away the Gu Poisonous True Sutra, breathed a long sigh, and his eyes were filled with spirit. Chu Nan felt that he had a vague breakthrough in his medical field through this "Gu Poisonous True Sutra".

Medicine and poison science are in line with each other. This is the same as what the old man said about the fact that medicine can kill people and save people. Poisonology also contains many medical truths. For example, the Gu Poison chapter talks about how to use Gu Poison to kill people. The Gu Poison chapter describes various ways to remove Gu Poison. During the study, Chu Nan also had a little more understanding in medicine and felt that his strength was further improved.

Of course, Chu Nan dared not say that he had reached the realm of a medical master, but when he was reading this book, Chu Nan found that Gu poison was to use a kind of Gu insect to harm people, but can't Gu insects save people? Chu Nan had a feeling that Gu poison could also be used in medicine. If this method of saving people could be studied, Chu Nan would probably be able to enter the realm of a medical master soon.

Just think about it, Chu Nan felt a little excited. It was not that Chu Nan cared about a false reputation, but a stubbornness. It was the same as treating martial arts. Chu Nan also had a stubbornness in treating medicine. Otherwise, with his amazing talent alone, how could Chu Nan reach the level of unprecedented success in medicine and martial arts at the same time?

In Chinese history, Chu Nan has set records in two fields as the youngest intermediate and youngest medical master!

After dinner, Chu Nan returned to the room alone and was immersed in the mystery of the "Gu Poisonous Sutra". For several consecutive days, Chu Nan even hid in the room alone even for dinner. Hu Niu personally sent the meal in and immersed in the "Gu Poisonous Sutra". Hua Linglong and Wu Bei were not disturbing Chu Nan, and the negotiations between Wu Bei and Tang Yarou were also progressing very smoothly. Because of Chu Nan, Wu Bei gave Tang Yarou a considerable preferential treatment and could sign the contract directly.

Five days later, Yin Zhaotian finished his pulse and prescribed medicine for an old man. The old man stood up and turned away with gratitude. Yin Zhaotian had just asked Hu Niu to call the next patient, but saw Chu Nan finally walked out of it.

"Master." Yin Zhaotian stood up, looked at Chu Nan with bright eyes, looking surprised. For some reason, Yin Zhaotian felt an indescribable temperament on Chu Nan.

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

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

"Is that right?" Chu Nan smiled and said, "I have gained a lot in the past few days. When I finish my work, I'll tell you when I go to my room."

Yin Zhaotian's eyes lit up. Chu Nan is now at the level of a master of medicine, which can make Chu Nan feel a great gain. It can be seen that Chu Nan must have gained a lot in the past two days, and Yin Zhaotian will benefit greatly after listening to it.

Yin Zhaotian hurriedly agreed. In the clinic, the disease that is usually extremely difficult to treat is handed over to Yin Zhaotian. Some minor problems were treated by Hu Niu and Wang Yue. Hu Niu followed her father to treat neighbors since she was a child. There was no problem with the minor problems. After all, Wang Yue graduated from a medical school. After so long, although her level was not as good as Hu Niu, she still had no problem with ordinary colds and fevers.

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

"master……."

"Yeah, I've never taught you much. I still feel guilty when I hear you call me Master."

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

"Haha, I know, sit down quickly. It is because I feel ashamed that I have to teach you some good things myself. Have you heard of Gu Poison?"

"Gu Poison?" Yin Zhaotian said in surprise, "I have heard that it is an extremely vicious method. It is said to be a witchcraft of the Miaojiang Gu tribe. Only extremely powerful wizards can use it. In fact, it is just a poison technique."

Chu Nan nodded and said, "You are right, but this poison is 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 Mountain Village, and the biggest gain was that I was exposed to the poison. After I came back, I studied it and learned a lot from it."

Yin Zhaotian hesitated for a moment, opened his mouth, and wanted to speak but stopped, but he was unable to speak out in the end.

Chu Nan knew what Yin Zhaotian wanted to say, and smiled and said, "Do you want to say that this is a vicious poison technique, and we doctors should not contact you?"

Yin Zhaotian nodded.

Chu Nan laughed and said, "Actually, I had hesitated at the beginning, and I had the same idea as you, but my old man once told me that poison science and medicine are actually in line with each other, and there are many connections in it, and we can learn from each other. For example, there is a saying in medicine that uses poison to fight poison. Isn't it? After I thought of this, I started to study behind closed doors in the past few days, how to study how to cure diseases and save people from Gu science. As a result, I really studied it and I could share it with you."

Chu Nan has indeed learned a lot from the "Gu Poisonous Sutra" these 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 situation, he will definitely be very pleased.
