All resources and skills are monopolized by the upper class. The only way for civilians to survive is to fight with their lives. Lu Ye's father died in the war and his mother disappeared. The family shares that he was supposed to inherit were cleverly taken away by his uncle Lu Gan. Even the admission spot to Longwu University that his father paid for with his life became a stepping stone for Lu Qian to pave the way for his daughter. What's even more crazy is that Lu Gan actually wanted to dig out the meridians of his sister who was a martial arts genius alive, just to let his daughter reach the sky in one step, and even threatened her sister's life to force Lu Ye into a dead end.

As Lu Ye used killing to prove his truth and used force to stop fighting, huge evil forces gradually emerged, and a sweeping murderous intention had just begun.
