Reborn, Xiao Chen is both the last survivor of a northern border family and the much-despised live-in son-in-law of the Anyuan Marquis's household. Silent and taciturn on the surface, he is regarded as a martial arts cripple. In truth, he has a System and is a reincarnated strategist well versed in political intrigue. He quietly lays his plans from humble beginnings, swearing to take revenge and uncover the mysteries of his past life.
His wife, Lin Qingxuan, is the marquis's daughter. Forced into the marriage at first, she is cold and distant, but as turmoil unfolds, feelings begin to grow between them, and they endure the trials of the "chasing one's wife to the crematorium" trope together. At court, Qin Yuan, a shrewd chancellor who rose from humble origins, harbors treasonous ambitions. Princess Chu Yuehuang, the cold and noble regent, commands the palace's shifting power plays. There is also Mo Chen, a mysterious sorcerer who glimpses the secrets of fate, and Han Lie, a loyal former subordinate who pursues the truth.
Xiao Chen navigates the inner household, the imperial court, and the martial world. Guided by System missions, he sets out on a defiant path from live-in son-in-law to emperor. Interwoven vendettas and political machinations set off a storm that sweeps across the dynasty and the lands of foreign peoples, all because of him.
