Holy Hand Poisoner

Born with a missing soul and no memory of the past, he is a fool in the eyes of the world. The doctor who saved the world was turned into a human-shaped poison, a walking disaster. But he has not lost his true nature, dragging the most poisonous body in the world and carrying the clearest heart, walking around the world. As a result, there is an extra fool in the world who specializes in treating incurable diseases. The famous doctors were trembling with anger: "What are you doing? Fighting poison with poison, no, you are destroying the world!" The fool smiled naively: "Isn't it enough if I can save people?"
