I Summoned a Fake Ancestor

My name is Lin Cheng. I was discussing the murder of a female classmate in the dormitory last night, and in the blink of an eye, a real ghost ripped out my heart. When I opened my eyes again, I became the "ancestor" that Li Zhen, a loose cultivator from another world, bought with two buns. The grandson found out that the person he invited was an impostor, so he wanted to take me as an experience bag. But he doesn't know, What I bring is the madness and laws of another world. Want to devour me? Then let's see who is whose nourishment! ——Wait a minute, this shabby body at the third level of Qi training seems like it can't even eat?
