Li Chen is the lowest peripheral member of the "Dragon King Palace" and was sent to be a son-in-law as a test. He thought it was exile, but he didn't know that it was the ultimate test for the heir to the palace master. In the process of pretending to be a pig and eating a tiger, he integrated resources, met giants, and established his own business empire. When the three-year period expired and all the senior officials of the Dragon King Palace knelt down to welcome the new master, everyone was shocked to realize that this counterattacking son-in-law had already become the real king.
