In order to resist the marriage, Su Wan recruited Lin Shen to marry him. In the past three years, Lin Chen was known as a loser, while Su Wan struggled to qualify for inheritance amid family rejection. At the Su family birthday party, everyone humiliated Lin Chen in public, and Su Wan was criticized for defending her husband. Just when everyone was about to trample the two people into the mud, Lin Chen received a call from the president of a multinational group, revealing for the first time a shocking background. Since then, crises in the Su family have broken out one after another. When her cousin seizes power, the group is shorted, her parents fall ill, and her relatives run away with their money, Su Wan is forced into a desperate situation. Lin Chen then closed the net step by step as a "waste son-in-law", first clearing out the internal enemies, and then killing the external enemies, gradually uncovering the real reason why Jiangzhou Capital was hunting down the Su family. With the launch of the "Skynet Project", Lin Chen's true identity gradually emerged: he was not a son-in-law who turned over by luck, but an heir to a top-level conglomerate who retired. The internal strife among the Su family, Zhao family, Shen family, Beichen Society and even the male protagonist's old family are connected by an old case that has been buried for three years into a huge black web. In the end, Su Wan completed the transformation from a neglected daughter to the helm of the group, and Lin Chen also completed the final settlement of old enemies and old debts.
