Wei Erdan is a tall, handsome dimwit at his company. With no parents and no one to look after him, he sneaks into a temple every night to steal the gods’ offerings and eat them, then sleeps beside one of the gods. The god is lecherous and secretly lustful, longing to have women on both arms and revel in a life of drunken pleasure. So he comes up with a plan: he sneaks into Erdan’s dreams and makes a pact with him. The god grants him three abilities: 1. Divine medical skills, 2. Immortality, 3. An invincible right hand. In return, Erdan must enjoy the peak of human life on the god’s behalf.
It’s easy to imagine what kind of life Erdan wants. Naturally, he starts out as a divine doctor, since that lets him get close to women’s bodies, then enjoys life to the fullest, gathers beautiful women into his harem, establishes a medical alliance, invents divine medical techniques, teaches each wife a different one, and takes control of the entire medical world. As for himself, he rises to the peak of life.
