Kai Zhenwu was once the War God—feared by demons, respected by the heavens. But after being betrayed by the Twelve Supreme Deities, his power shattered and he was cast into the mortal world. He wakes up in the body of a “worthless son-in-law,” a man everyone looks down on. For three years, he’s endured humiliation in silence. But when his wife Chen Wei’er becomes the target of a powerful billionaire and an ancient assassin clan, Kai can no longer hide. His lost power begins to return piece by piece. As he searches for his remaining fragments, Kai uncovers a deeper conspiracy: a cult that hunts gods, a weapon meant to kill him, and a prophecy that says he might be the one to end the world. Now, with ten thousand years of battle instincts and nothing left to lose, Kai Zhenwu rises again not for glory, but to protect the only person who ever treated him with kindness. And this time, the heavens will learn a simple truth: you can betray a god, but you can’t break him.
