In the Sanlin Star Region of the Federation, Xu Le, an orphan from Donglin, works at mechanic Feng Yu's repair shop, learning both ancient martial arts and mechanical techniques from him. One day, when the Federation military corners Feng Yu, Xu Le becomes caught up in the conflict, turning him into a wanted fugitive.
After Feng Yu is presumed dead, Xu Le replaces his own chip with one Feng Yu left behind, leaving him uncertain about his true identity. Adopting a new name, he enrolls at Xinglihua University in the capital. There, he encounters Jian Shuier, a Federation celebrity; Tai Zhiyuan, a descendant of the former royal family; Shi Qinghai, a spy from Qinglong Mountain; and Zhang Xiaomeng, another Qinglong Mountain operative. For the first time, Xu Le pilots a mecha and is thrust into combat.
