Qin Mo, a good-for-nothing abandoned by his tribe, received a fire stick from his fiancée Su Qingxue on the day he broke off his engagement. Unexpectedly, the stick turned out to be the ancient fierce soldier 'Slaying the Sky'. With a slash of the knife, the void shattered, and Qin Mo embarked on a path of cultivation that defies heaven. However, the fierce soldiers attracted the covetousness of all parties: Zhao Wuji set up an ambush to pursue him, Liu Ruyan secretly instigated him, and only the weapon spirit Baize and the fox girl Qingluan truly helped. When Qin Mo gradually uncovered the ancient conspiracy behind the murderous soldiers, he discovered that Su Qingxue's broken engagement hid a shocking secret - everyone was waiting for the moment he cut through the sky.
