Demon-Slaying Hand

My name is Su Mo, a third-level disciple of the Zhengyang Sect, and a descendant of the Su family. I learned swordsmanship from the retired old housekeeper of the Bai family for several years. I have been in a position that is neither good nor bad. My biggest dream is to move up the ranks and be allocated better training resources. Until that cleaning mission of Yuandao Mountain. A guy wearing an evil ghost mask opened the Gate of Yama and released the demon who destroyed Yundao Mountain seven hundred years ago - Yan Tuming, the first head of the Yan family. The guy got into my body and tried to take my body. He failed. Or should I say, he was half successful. Yama's destiny failed to occupy my consciousness, but it took root in my left hand. From then on, I could freely control the death energy with my left hand. A disciple of the Zhengyang Sect who is obsessed with promotion, and a world-destroying demon imprisoned in his left hand, are forced to embark on a road that leads to nowhere. Ahead there is the conspiracy of the masked man, the surveillance of the Zhengyang Sect, the critical survival of the world, and an unsolved mystery - is my left hand locked with a knife, or is it a beast that is about to break free?
