Lin Fan was once an ordinary teacher in a small town. An accident made him the son-in-law of the wealthy Su family. What I thought was the beginning of a new life turned out to be an undercurrent: family power struggles, old love rivals scheming, relatives looking down on me, and my identity being ridiculed. With his humor, optimism and extraordinary wit, Lin Fan gradually showed his talents in the cracks of the Su family: resolving the family crisis, winning the trust of his father-in-law, and transforming from mutual distrust to true love with Su Waner. He struggles to navigate between funny daily life and sinister plots. He not only has to play a small character to fight monsters and level up, but also serves as the family's fire brigade. There are crises and turning points in each volume. From the humble son-in-law to the pillar of the family, Lin Fan used his actions to achieve the reverse turn from "the son-in-law" to the "head of the family", and finally ushered in his new life with humor, warmth and storm.
