Cui, a little-known surname, carries a family full of blood debt. Kuang Heng, once the eldest son of the Marquis of Zhenguo, is now the laughing stock of the entire Dajing court - he was born with blocked meridians, unable to practice martial arts, and unable to make plans. He was dubbed a "waste" and is living on his last breath. His father and brother were killed in battle, their bodies still cold, the prince's mansion was raided, and everyone was exiled. Only he was left in the capital for being "useless" and became a plaything for the powerful. The emperor regarded him as a pawn to restrain the old ministry, and the powerful ministers regarded him as a tool to relieve their boredom. Even his fiancée, who had once loved each other, broke the engagement in public, stepped on his dignity, and married into the Eastern Palace. His dignity was cut away, his pride was broken, he was trapped in a small place, he saw all the humiliation in the court, and suffered all the hardships in the world. Everyone thought he would dissipate like dust, but they didn't know what broken obsessions and suppressed hatred were hidden in this useless body. Abuse the body, mind, and bones, there is no sense of counterattack, only endless purgatory. Falling from the clouds into the mire, from hope to despair, Kuang Heng's road to the court is a dead end road paved with blood and tears, with no turning back.
