After transmigrating into the body of Jia Huan, a despised concubine-born son of the Jia family, he refuses to live an ordinary life. He borrows silver from Wang Xifeng to buy a position and joins the Embroidered Uniform Guard. With justice in his heart, he earns martial arts cultivation through capturing criminals and accumulating merit. He successively apprehends a vicious monk, criminal gangs, and corrupt officials, impartially investigates a major embezzlement case involving an embankment, and exposes corrupt parasites in the Ministry of Works. At home, he cares for his birth mother and treats those around him kindly. Though his principles conflict with those of the Jia family, he remains steadfast in upholding the law. Outside the household, he wields his Xiuchun saber to punish the wicked and protect the people, rising from a low-ranking strongman to a Hundred-Household Commander. Set against the backdrop of Dream of the Red Chamber, the story portrays a young man's inspiring growth and celebrates integrity, public service, the elimination of evil, and the protection of the people.
