Fake People Also Want to Practice Immortality

I am a fake, and my task is to play the role of an ordinary human. But I traveled to a modern world of immortal cultivation, and the old man next door could kill ten of me with one punch. In order to blend in with humans, I was forced to work part-time and pretend to be a cultivator. This world is so scary, Mom, I want to go home QwQ! ! !
