After practicing in the underworld for thousands of years, Sun Wukong was preparing to support his child. When he saw the old lady beating and scolding his daughter-in-law Yuzhen, he discovered that the old lady was a child-bearing spirit. So Sun Wukong turned into Yuzhen and entered the Lin family.
Sun Wukong told Yuzhen to buy a mansion and hire servants for him in the suburbs, so that she could rest in peace and recuperate. Yuzhen is getting better but cannot leave the forest.
Mr. Lin went home and saw that Yuzhen was in better spirits and was planning a marriage after his wife's death. The old lady tried to beat and scold Yuzhen but she always got hurt. Sun Wukong also turned the old lady's tea into the smell of urine.
Sun Wukong managed the entire family, including his unruly sister-in-law, to be obedient. Yuzhen's husband is having troubles outside, so Sun Wukong tries to teach her a lesson. Various scandals in the Lin family were uncovered by Sun Wukong, and the family fell into chaos. Finally, under Sun Wukong's supervision, everyone in the Lin family began to reflect and change, and Sun Wukong left after completing his mission.
