To the outside world, he is a useless son-in-law who married into the Lin family three years ago and has endured their disdain ever since. He takes care of all the household chores, keeps his head down, and lets the Lin family’s relatives bully him. Everyone thinks he is incompetent, timid, and good for nothing. In truth, he is the former leader of Huaxia’s elite special forces team, codenamed Dragon King, and the founder of the mysterious, powerful Nine Dragons Pavilion. He is a peerless fighter, a meticulous strategist, decisive and merciless in battle, yet deeply loyal to those he cares about. Three years ago, after a trusted subordinate betrayed him and his enemies ambushed him, he survived by sheer luck. To repay Lin Zhenhai for saving his life, evade his pursuers, and protect his wife and daughter, he willingly concealed his identity and became a live-in son-in-law. All the while, he kept his anger bottled up, waiting for the chance to exact revenge and clear his name.
