A drinking game led Wang Yan to travel back to the 1970s and learn ghost hunting from Niubi's father.
When the pupil technique is activated: the evildoer will die quickly.
Ghost: You are not a human being, and neither is your father...
Demon: This man is eating a demon, can anyone help him?
Wang Yan: If you don't die, will I die?
Wang Dashan: He is indeed my son. He is exactly the same as me.
