Rebirth: I Am One Person

Just an old man who goes back to his youth and continues his idle life? I made a mistake in typing "Li Tian changes destiny", but suddenly I feel that "Li" is better than "Reverse" The game the male protagonist played before he was reborn with the system, hanging up to cultivate immortality, and then discovered that this world is not the original world, but a world mixed with supernatural powers, ancient martial arts, vampires, werewolves and other elements.
