Fourteen-year-old Shen Yu traveled to the Shen family in Yunmu County in a fantasy world. It happened that his father Shen Feng and all the family elites died fighting for the inheritance of Xiao Xuan, a strong man in the Yuandan realm. The Shen family fell into evil slaves (Li Si, Zhang Gao) who coveted the family property and the mountain. A desperate situation threatened by thieves (Longying Village) and squeezed by government forces (Chen Hanshan, Lu Dongsheng); in critical moments, Shen Yu activates the killing system and gains killing points by killing enemies to improve his cultivation (gradually breaking through from the third level of body forging to the fourth level of Qi Sea)
