I Traveled Through Time and Became the Ancestor of the Immortal Sect

Immortal Sect Boss: Are you saying that you are not the reincarnation of our ancestor? Me: Really, I'm just an ordinary person? Immortal Sect Boss: Then how come you are as handsome as the ancestor when he was young and can still practice the ancestor's skills? Me: I'm just more handsome, luckier, and more qualified. There's no need for you to chase after calling me ancestor! Shen Pei traveled through time overnight. He thought that all those who traveled through time had their own cheats and reliable systems, but he never expected that he would actually be transported into the body of a mortal. [No system, no Holy Mother, funny cultivating immortality]
