Xu Zhaolin's face turned pale with fright, Ye Fan was simply too crazy. Having visited some foreign scientific research institutions, Xu Zhaolin had seen some insane doctors abroad who, to develop antitoxin serums and better experience the symptoms of poisoning, would inject themselves with some venom. However, the amount injected was so minimal that it was basically not life-threatening.
Moreover, before doing so, they would experiment on mice to determine the amount of venom the human body could endure.
Even so, this was already considered crazy, but compared to Ye Fan, it was nothing short of child's play.
