The invincible Li Daoyi and his daughter Li Anan live in seclusion in a small town at the foot of Qingyun Sect Mountain, living a "mortal" life like salted fish. In order to give his daughter a normal childhood, he disguised himself as a low-level monk at the first level of Qi training. Daughter Li Anan is a little kid full of chivalrous dreams. She thinks about "slaying demons" all day long, and is deeply worried about her father's "weakness", so she starts a series of hilarious operations to "help" her father.
The "stray cat" she picked up was an ancient mythical beast, and the "rags of metal" she used to play house were ancient artifacts. Behind every "little trouble" she caused was a powerful force that could shake up the world of immortality. Li Daoyi, on the other hand, had to use various seemingly "coincidence" and "luck" methods to quietly solve all crises and maintain his "waste dad" persona in a corner where his daughter could not see. The entire world of immortality was being tossed around in the "daily life" of the father and daughter, but Li An'an always believed that his ability to grow up safely was all due to "good luck."
