I Have Been in the Sect for Eight Hundred Years and Have Become an Ancestor?

Chen Fan traveled through the realm of cultivation and was bound to the [Immortality System], which allows him to become stronger as long as he lives. He worked in the outer sect of Qingxuan Sect for eight hundred years, and became the only "ancestor" of the sect from being a handyman. Just when he was about to continue to survive until he ascended, a group of demon cultivators came to the mountain gate, pointed at him and said: "This piece of trash, kill him with one palm!" Chen Fan sighed and took action for the first time in eight hundred years - Then, the sky fell.
