After the end of the mechanical war, self-repairing mechanical units are still raging in the wasteland. As a "mechanical hunter", {Su Rui} hates machines because his parents died in the war. During a mission, he captured "Xiao Qi", a small service robot with the mind of a child. His innocence and kindness unexpectedly shook his obsession for revenge. At the same time, behind the frequent mechanical riots, the shadow of the "Mechanicus" emerged - they attempted to resurrect the mechanical master "Apocalypse" and restart the war. In order to prevent the crisis of annihilation, Su Rui was forced to cooperate with Xiaoqi, using its sensitivity to mechanical networks to track the traces of the cult. Along the way, Su Rui gradually realized that machines are not inherently evil, but just victims of war.
