On the surface, he is a useless son-in-law who has married into the Lin family for three years and has been looked down upon. He does housework every day, talks down to him, and is bullied by the Lin family's relatives and friends. He is incompetent and weak in the eyes of outsiders. His true identity is the former captain of China's top special forces team, codenamed Dragon King, and the founder of the mysterious top force Jiulong Pavilion. He is extremely skilled, thoughtful, decisive in killing, and values love and justice. Three years ago, he was betrayed by his cronies and plotted by his enemies. After narrowly surviving, in order to repay Lin Zhenhai for saving his life, avoid being pursued by his enemies, and protect the safety of his wife and daughter, he was willing to remain anonymous and become his son-in-law. He always held back a resentment in his heart, waiting for the opportunity to revenge and clear his grievances.
