Bai Xiao was transformed into an abandoned son of the Qin Dynasty. He was frail and sick, and lived with a mysterious old man in a fishing village. It wasn't until the old man passed away that he learned that the other person was Bai Qi, the God of Killing, and awakened the "Great Qin Human Massacre" system. To undo his curse, he must embark on the battlefield. When the Qin army faced the Xiongnu cavalry, Bai Xiao, dressed in white, walked out with a sword and said softly: "I will finish Grandpa's journey."
