The Marquis of Zhenbei's legitimate eldest son, Shen Fusheng, only learned to speak at three, could not recognize all characters at seven, and the entire capital laughed at him as a foolish heir who is mud that cannot be plastered onto a wall. Humiliated publicly by his younger brother, driven into a dilapidated courtyard by his stepmother, and trampled underfoot by everyone. No one knows that his mind seals ten thousand years of memories of an ancient civilization. A fire, an assassination, a jade pendant awakens. The Eye of Grasping Objects, the Art of Vertical and Horizontal, the Knowledge of Creation—three stages of memories unlocked one by one. The foolish heir stops pretending. Investigating corruption, exposing smuggling, fighting the grand preceptor, breaking into the imperial mausoleum, going to the battlefield. From a laughingstock of the capital to wielding power over the imperial court, from being at everyone's mercy to turning the tables with a butcher's knife.
