The special forces soldier Wang Rongma spent several years on the battlefield. He followed the orders of his master and went down the mountain to marry into the Su family. He changed his name to Sui Yi and worked as a seemingly useless son-in-law for three years. He secretly helped his wife's family clear obstacles to their trade routes and slapped the rich and powerful who looked down on him. Finally, he revealed his identity and became a hidden boss, protecting the family's safety and security.
