In the future interstellar era, Cai Ruben is a low-level scavenger, suffering from social oppression and struggling to survive. Technological hegemony forces control resources and power, and treat those at the bottom like nothing. Cai Ru accidentally obtained a mysterious system, which became an opportunity for him to change his destiny. However, the technological hegemony sensed the threat and began to pursue and intercept him, hindering his access to resources and growth. Not only was Cai Ru weak in strength, he was also discriminated against and misunderstood because of his lower-class status, and was considered unlikely to become a great person. At this time, alien creatures are about to invade, and the race is facing a life-and-death crisis. Cai Ru must rely on the system to quickly increase his strength within a limited time, challenge the technological hegemony and the ruling class, and lead the race to resist alien creatures. In the process, he must also resolve misunderstandings and prejudices from the outside world, and finally achieve a counterattack from a low-level scavenger to a race hero.
