The Supreme Poison Demon Becomes a Pharma Chairman

Three hundred years after mana transformed Earth and nearly destroyed civilization, a young man is born with a condition that turns the very energy everyone else relies on into poison. Unable even to awaken, he is preparing to die when his soul connects with a version of himself from another dimension: Dang Gun-ak, the feared Absolute Poison Demon of Murim. The encounter introduces him to a discipline built around poisons and their cures. On an Earth rebuilt around mana, those techniques give the rejected young man a way to survive—and the means to develop medicines, build a pharmaceutical company, and confront enemies who underestimate what he can do.
