He Tieshou and Lan Fenghuang are both people from scenic spots, which are vast in territory and good at making poisonous insects and beasts. Moreover, the Miao family has a set of breeding skills and cultivation methods passed down from generation to generation, so the ability to use poison is superb, and others are on their way unconsciously.
Ouyang Feng is called Du, and his ability to use poison is brilliant. What's more special is that Ouyang Feng's ability to use poison comes from snakes. The venom he cultivated is even more toxic as long as it is stained with blood. Just one drop can kill countless sharks in the sea. And his ability to control snakes is also very good. A few whistles can make thousands of snakes obey orders.
Wang Nangu is the wife of Hu Qingniu, a medical fairy in Butterfly Valley. They are brothers and sisters in the same school, but Hu Qingniu studied medicine and Wang Nangu studied poison. The genius of Wang Nangu is that he doesn't have to breed any poisonous insects, poisonous snakes and scorpions, only natural poisonous weeds can kill people. But no matter how strong her poison is, it can't compare with Hu Qingniu's medical skill. No matter how severe Hu Qingniu's poison is, it can be solved.
To say that the first expert who used poison in Jin Yong's novels was not Ouyang Feng or He Tieshou or Lan Fenghuang, but a young girl Cheng Lingsu. Cheng Lingsu is a close disciple of the drug Lord Chen Wu. He is better than others, not only poisoning the invisible, but also cultivating the world's first exotic poison-seven-heart begonia, which even master Chen Wu failed to reach.
Summary: In fact, it is not difficult to see that all the people who attack with drugs are women except Ouyang Feng, because women are weak and can only improve their strength in this way. Cheng Lingsu is the most knowledgeable person in Jin Yong's novels, and if you ask Ouyang Feng, He Tieshou and Lan Fenghuang who was the first expert in drug use, I think it was Ouyang Feng. Du's name is not for nothing, and his snake venom can't even help Huang Dou.
