Above the steel wasteland, gunpowder smoke never disperses, and corpses are the road. Akano led his company deep into the restricted area to perform a "scavenger" mission, but due to a cover-up rebellion, he personally buried the entire company - including his most trusted lieutenant. The survivor Lu Xiao, whose eyes were eroded by acid rain, used his hearing and memory to reconstruct the truth of the battlefield. The two met again in the scrap iron jungle, one carrying the crime of killing his friend, and the other embracing the spirit of revenge. They no longer believe in orders, only bullets and blood. In this steel cemetery abandoned by the military, Akano and Lu Xiao, one light and one dark, one blade and one shield, tore apart the illusion of peace forged by the upper class, letting the silent ruins issue a deafening accusation.
