Yun Zhaohan is the most disliked cleaner in Neon City. He drags a rusted mechanical bucket through the ruined alleyways every day and is scolded as a remnant of the old era. No one knows that there is a rune under his left arm that can awaken the sleeping armor, and he is the last tombkeeper of the old era. When Ji Shuye, the most cold-blooded military hunter in this future city, was ordered to hunt down the "source of pollution", he saw Yun Zhaohan break off three surveillance drones with one hand for the first time in the garbage dump of the slum. Those silent eyes actually reflected the firelight when the starship crashed thousands of years ago.
