The Heavenly Demon Sect was only a sect that used poison in ancient times, and it was passed on to modern times before it withered, and the descendants were almost extinct, and Li Nanxing's father always remembered the ancestral teachings, and taught Li Nanxing to recognize poison and make poison since he was a child, in order to prevent the poison of the Heavenly Demon Sect from declining.

The terrible thing about poison is that you can't prevent it, you don't know how to die, and the death is extremely miserable, and Li Nanxing, as the only master of poison in the dragon soul, is naturally well-known by people on the road, although few people have seen him, but there are really a lot of people who died in his hands, so he was named the "poison king".

Although there are not many people Lin Fan knows who use poison, after staying in the dragon soul for so many years, Li Nanxing's poison technique Lin Fan still has a certain understanding, in Lin Fan's opinion, this brother of his is definitely worthy of the nickname "Poison King"!

In ancient times, the treasure of the Heavenly Demon Sect was called the Nine Turns Golden Needle, although the name is good, but in essence it is also a tool used for acupuncture, this thing has a total of different sizes, nine golden needles of different lengths, at that time, only Chinese medicine prevailed in China, Western medicine was introduced in modern times, and for Western medicine, these things are dispensable, but for Chinese medicine, a good set of acupuncture tools is often a pity to play a miraculous effect.

In fact, in ancient times, the nine turns of the golden needle is not used to save people, but used to kill people in the invisible, it is said that the nine golden needles perennial with poison soaking, the medicinal effect has been soaked into the golden needle, once the skin of the person is pierced, if the treatment is not timely, it will bleed to death.

As for what kind of poison is on the needle, there is no way to verify it now, because with the passage of time and the accumulation of years, when it reached Li Nanxing's hands, the toxicity on the needle was already very weak.

Acupuncture can also kill people, but also save people, so after Li Nanxing's treatment, the poison on the needle has gradually dissipated, with nine turns of gold needle for traditional Chinese medicine treatment, than the effect of ordinary acupuncture tools I don't know how many times better, although it is not as magical as said in the TV movie, the needle to the disease, back to life, but it does have the effect that ordinary acupuncture tools do not have.

However, it is precisely because of this set of nine-turn golden needles that the Li family has been destroyed.

The Li family has lived in the countryside for generations and is not very rich, but usually the villagers will help each other, so life is not bad. The Li family has a neighbor who went out to work a few years ago, and when he came back, he was already a successful businessman.

But because of these years of traveling, this neighbor first contracted rheumatoid arthritis, lumbar disc herniation, and cervical spondylosis. Li Nanxing's father is a well-known Langzhong in the village, seeing that everyone is from the same village, and they are still neighbors, plus the relationship between the two families has always been good, so he used acupuncture to help him treat, and it only took a few days to see results, although it is not a complete cure, but it is rarely recidivized.

Since then, this neighbor will basically bring a large bag to Li's house every once in a while, and ask from time to time about the origin of the Nine Turns Golden Needle, and Li Nanxing's father just briefly mentioned it, saying that this is his family heirloom.

This neighbor was a successful businessman and felt that it was profitable, so he began to introduce customers to Li Nanxing's father, intentionally or unintentionally, hoping that he could sell this set of nine-turn gold needles as auction items, but Li Nanxing's father refused to sell them. But this neighbor still didn't give up, and came to Li's house more often, and finally had a big quarrel with Li Nanxing's father, and then for the so-called interests, he began to frame Li Nanxing's father.

This neighbor pretended to apologize, Li Nanxing's father naturally didn't care about these things, but who knew that this neighbor would take revenge in the end, when Li Nanxing's father was treating the patient, he secretly moved his hands and feet in the medicine, and the patient died innocently, and the neighbor gave some gifts to the steward above, and as a result, Li Nanxing's father was also charged with murder and sentenced to 20 years in prison.

Unbearable, Li Nanxing's father committed suicide in prison not long after. And the neighbor didn't get the nine-turn golden needle, obviously the thief is not dead, relying on his business relationship over the years, he actually found some gangs in the society, and a fire burned the Li family to the ground, except for Li Nanxing, all of them were buried in the fire.

Because it was in the countryside, this matter did not attract the attention of the upper leaders at all, but at this point, Li Nanxing's personality has changed a lot, he was only seventeen years old at the time, he was highly poisoned in the neighbor's home, so that the neighbor's family had no life, and he himself fled abroad, met Han Feng when he was poor, was brought back to the dragon soul, and became a hygienist in the organization.

Li Nanxing's ability to cure diseases and save people, no one in the Dragon Soul doubts, because he often goes out on missions, sometimes he needs to go deep into some primeval forests, swamps and deserts, and it is inevitable to get into all kinds of diseases, but these seem to be so vulnerable in Li Nanxing's eyes.

Similarly, no one doubts Li Nanxing's ability to use poison, which is definitely stronger than his ability to save people. It is said that killing people is invisible, although it is an exaggeration, but it is also true. The poisons he prepared were sometimes sent to the hospital for analysis by the so-called experts, who could not figure out what exactly made some drugs that were supposed to cure diseases and save lives have such great toxicity.

However, due to the changes in his family, the poison art that Li Nanxing learned was not only used to cure diseases and save people, but also to kill people! If it weren't for this reason, Lin Fan was suspicious that if his brother reappeared and joined the medical field, maybe the decline of Chinese medicine would be greatly improved.

Speaking of Li Nanxing's life experience, it is indeed a bit similar to Lin Fan's, but the difference is that Li Nanxing's revenge has been avenged, but Lin Fan has no confidence in revenge at all, and always feels that it is far away, because of what happened so many years ago, Lin Fan basically has no way to start even if he wants to investigate, the only hope is the purple sword, as long as the purple sword is in his hands, Lin Fan believes that those black-clothed people back then will definitely appear.

Because the old ghost suddenly had no news, so that the thousands of troops under his command suddenly lost their backbone, and Li Nanxing's attack was sudden, and the vast majority of people were all buried under Li Nanxing's poison without a trace of resistance.

The medicine is very violent, and when he smells it, he immediately bleeds to death, and there are corpses everywhere on the mountain, the scene is extremely cruel, but Li Nanxing's complexion has not changed at all, and his ruthless eyes make people feel cold through their hearts.

Among them, a small number of people who were lucky enough to survive were also captured by the Blue Flag Army who came later, as for whether Jin Zhengyang recruited them or killed them, Lin Fan did not let Li Nanxing take care of it, there was already a river of blood here, Lin Fan's goal had been achieved, and the rest were naturally dealt with by the soldiers of the Blue Flag Army.

When Li Nanxing rushed back, it was already a day later, and the old ghost was under the attack of Zhang Lei's perverted **, and the will of the whole person was indeed about to be destroyed, but no matter how you say it, he is a hegemon, and he was born as a soldier, and his willpower is naturally much higher than that of other people, so he just held on, gritted his teeth and persevered, and never said who was behind the scenes, which really made Lin Fangao look at him.

Lin Fan took Li Nanxing, Zhang Lei, and Xu Qiang to the secret room, Jin Zhengyang did not follow, saying that he was not feeling well, but Lin Fan also knew that Jin Zhengyang was just a little guilty, after all, the old ghost was deceived by him as an intermediary, and the two had cooperated a few times, no matter how they said it, they were so friendly.

This is just as Lin Fan said, there is no so-called loyalty or disloyalty, the reason why he is loyal is only because the bargaining chips for betrayal are not enough. In this era, some people can even sell their own parents for monetary profits, not to mention old ghosts who don't have much affection for Kim Jongyang.

Of course, Lin Fan is also very clear that the relationship between himself and Kim Zhengyang is not as harmonious and intimate as it seems on the surface, at least not now, although the last conversation saw sincerity in Jin Zhengyang's eyes, but Lin Fan will not pour out his heart and lungs to him because of this......
