Reborn fifty years into the past, he binds himself to a "Contribution Points System" that rewards him for advancing human civilization, such as spreading martial arts from the future, improving technology, and uniting factions. These rewards heal his old injuries and increase his strength. He prevents his younger sister from turning evil, fights against beast hordes and the schemes of ancient gods, establishes the "Remnant Star Society" to break the monopoly of superhumans, and unites the forces of Earth and other worlds, ultimately rewriting the fate of civilization.
