Three years ago, Chu Yan, the eldest son of a top wealthy family, was betrayed by his fiancée and his brother. His family was ruined and he was exiled to the Death Row Prison on the Hell Island to serve as cannon fodder and a prison doctor.
In a desperate situation, he awakens the sin karma medical system. By treating diseases, he can rob criminals of their life span, ancient martial arts skills and hundreds of billions of wealth!
In the beginning of a riot, he used only a rusty wire and a ballpoint pen to complete a heart bridge with his bare hands in three minutes, shocking the entire island of the dead!
In the past three years, he has transformed the world's number one killer, the overlord of the dark web, and the godfather of the plutocrats into loyal and fanatical younger brothers.
Three years later, Chu Yan, armed with his superb medical skills and superb martial arts, became a village doctor in the community incognito, just to find his sister who was living on the street.
When an arrogant enemy came to visit with a world-class medical expert and laughed at him for being just an unlicensed traveling doctor.
But the high-ranking master suddenly knelt down, crying and begging him for advice on suturing techniques!
The top killer hired by the enemy who spent a lot of money was so frightened that he peed when he saw Chu Yan. He even crawled on the ground, kowtowed and called his ancestors!
Chu Yan held the silver needle in his hand and smiled like a Shura: "Not only can I cure diseases and save people, I can also kill you!"
