Li Changshou, a terminally ill young man, was accidentally reborn in the ancient times before the Conferred God War and became a Qi Refiner. In order to cultivate immortality and survive in the cruel prehistoric world, he kept a low profile, planned everything before doing it, never stepped into danger easily, hid his cards, practiced escape techniques, and refined poison pills. Until one day, his master suddenly brought him a junior sister back, and Li Changshou, who wanted to practice low-key, was involved in a series of adventures. He was as steady as an old dog when he didn't move, but he was shocking when he moved. After moving, he left quietly. While defeating evil enemies, he made like-minded friends and realized his own life value.
