Mortal Cultivation of Immortality: Starting from Swallowing Waste Elixirs

My name is Gu Shuangcheng, a time traveler. His spiritual roots are useless and his cultivation level is low. He is whipped every day when he chops wood. I thought I would be a coward for the rest of my life—— Until that day, a fairy fell on me. He ran away after sleeping and threatened me not to tell anyone. Okay, I tolerate it. But guess what? A tree grows out of my blood. The waste elixir is swallowed and the spiritual fruit is spit out. Eat garbage and your cultivation will soar. Now Manager Gong takes a detour when he sees me. As for that senior sister... Mortals cultivating immortals, let's build the foundation and see you again.
