"The Crazy Son-in-Law of the City God" tells the story of Lin Hao, who has lost his memory, as the Su family's son-in-law. After enduring the humiliation for three years, he awakens to his identity due to Zhang Heng's humiliation. He held the Supreme Black Card and summoned Long Yi, the leader of the Dragon Group, to easily resolve the crisis of the Su Group and bankrupt the Zhang Group.
It turns out that Lin Hao is a young leader of a top power. He was involved in a car accident designed by the Rothschild family in order to seize its core energy technology. He joins hands with his wife Su Ruoxue to take charge of new energy projects, fight against Keith and his family's forces, and crush their conspiracy.
Lin Hao later defeated Case Lao, took over the Rothschild family industry, and also devoted himself to public welfare, such as developing vaccines to control the African plague. His son Lin Nianxue and grandson Lin Sihao inherited his responsibility and continued to protect the world and fight against remaining forces and systemic crises.
