The Secret Book of Immortality Sewn in Grandpa's Pants

Grandpa always said that he had a secret book for cultivating immortals and asked Yu Ze to keep it secret. Yu Ze, a dignified college student, never believed it. Who would have known that he actually saw his grandfather soaring in the daytime that day. Yu Ze looked at his grandfather flying in the sky and shouted: "Grandpa, why didn't you take me with you when you traveled through time? I am your grandson after all. Even after graduating from college, I can't find a job with five insurances and one housing fund! " "My dear grandson~, Grandpa left the secret book at home for you. Grandpa will go find the way for you first~" Grandpa's voice became more and more distant. This novel and its characters are purely fictitious.
