Xing He, an internet-addicted shut-in, accidentally binds himself to an interstellar combat System in his apartment on Earth. From then on, he turns his life around, gaining a sharp gaze and an upright bearing, with blue light shining from his eyes in battle. But this power soon draws the wary attention of An Yuan, leader of the Dark Galaxy's bounty hunter organization. An Yuan issues a global bounty on Xing He, pushing him to the brink.
In his moment of crisis, the interstellar information broker Quantum Fox arrives for profit, sometimes helping him and sometimes betraying him. Mechanical Ji, a genius engineer from a mechanical planet who yearns to understand human emotions, uses cutting-edge mechanical gear to help Xing He escape danger. Through one life-and-death contest after another, Xing He goes from timid to brave, yet he knows that growth comes at a price, and every victory means more unknown dangers are lurking.
When an ordinary person suddenly gains extraordinary power and is swept into brutal interstellar conflicts, Xing He faces a difficult choice: how can he stay true to himself amid desire and justice? This is the ultimate question he must answer.
