In a chaotic age plagued by bandits, the young Chen Jing is taken in by Butcher Zhang of Shuang'an Town and learns the art of the butcher's knife. Blessed with a Heaven Rewards Diligence system, he can improve his skills through hard training, and a butcher's knife can also be used to slay enemies. After Butcher Zhang dies of illness, Chen Jing slays bandits to avenge his master's death. Recommended by Wang Chong, he becomes the personal disciple of Cheng Lianshan, master of the Lianshan Martial Arts School in Qingshan City. He earns resources by slaughtering pigs at the abattoir and forges bonds of life and death with his fellow disciples, foiling a conspiracy between a medicine shopkeeper and the Qingfeng Stronghold. But with the Qingshan Martial Arts Tournament approaching, the bandit chief of Qingfeng Stronghold is quietly setting a deadly trap.
