: The male protagonist Xiao Chen, the eldest son of the Qingzhou feudal lord, was the laughing stock of the world because his engagement was canceled in public by a noble lady from the capital in his previous life, and he eventually died in depression. On the day of his rebirth and return to marriage, he activated the "Event Selection Causality System" and, facing the humiliation, resolutely chose to marry the person who was granted marriage by the royal family, the "Ninth Young Master" who was rumored to be lingering on the sick bed and without any power. On the wedding day, the true identity of the "Ninth Young Master" - Empress Murong Zhao was quietly revealed. By relying on various "abnormal" choices made by the system, Xiao Chen not only defused a series of murders from the noble family in the capital and political enemies in the court, but also assisted the empress in consolidating imperial power, quelling the chaos of the feudal lords, and resisting foreign enemies. In the process, Xiao Chen grew from a dandy prince to a capable minister and emperor's husband who wielded power. The main storyline centers on the couple's Machiavellian love, from testing each other, using each other, to joining hands to control the world. It is interspersed with various unexpected choices and causal reversals brought about by the system, focusing on the exciting points of "anti-routine annulment", "the empress' backing", "behind-the-scenes" and "husband and wife team building a career".
