Qin Hao wakes up in an otherworldly battlefield, becoming the son of a wrongly accused God of War exiled to the border. On the verge of death, he relies on a double-layer sea of consciousness to inherit the weapon souls of the dead, wields a tiger-head saber to slay demons and survive, and grows side by side with the female general Chu Qing. Wanting to protect his family, he is instead targeted by a demon spy who destroys his home and abducts his younger sister, forcing him to step into Chisha, where thirty thousand dead soldiers are buried. His father's legacy armor reappears, the imperial court's demonic disaster gradually reveals itself, and he also steps from a foreigner only seeking to survive onto the path of saving family members, fighting strong demons, and guarding the mountains and rivers.
