On the surface, Yu Tu is the humble, obedient live-in son-in-law of the wealthy Lin family. But he hides another identity: he was once an elite operative in a top-tier intelligence organization. He had hoped to live an ordinary life under an assumed name, but the moment he entered the Lin household, he was swept into unfathomable family power struggles and a covert urban war.
His father-in-law, Lin Zhentian, treats him with contempt; his wife, Lin Qingya, keeps him at a distance; and his old enemy, Qin Yue, closes in with one deadly trap after another. Yu Tu has no choice but to dust off the skills he had long buried. An apparently ordinary banquet conceals wiretapping and murder. A mysterious chip leads to a vast network of illegal trade. And the supposedly invisible live-in son-in-law turns out to be the only key to unraveling it all...
As a larger conspiracy behind the family feud gradually comes to light, Yu Tu discovers that he's facing more than the open and hidden attacks of the business world: a shadowy organization is also closely tied to his past as an operative. He must protect Lin Qingya, race against time, expose Qin Yue's plot, and reclaim the honor and dignity that are his.
This is a story of endurance, awakening, and retaliation: the strongest live-in son-in-law will be silent no longer!
