Chen Sha arrives in a world of immortals and martial arts, taking on the mantle of the leader of the world's number one sect. The previous sect leader's dying words were: "Until you become the world's number one, you are not allowed to leave the mountain." Thus, he diligently cultivates, transcends his body's limitations, and confronts powerful figures throughout history. Many years later, Chen Sha recalls the day he descended the mountain; from that moment on, he was the world's number one. Even after countless eons, with the return of gods and demons, the appearance of Buddhas and immortals, and the resurgence of ancient powerhouses and gods, he remains the world's number one, unchanged.
