Reborn in the Starry Apocalypse: I'm the Only One with a Guaranteed Safety Net

[Sci-Fi Space] [Sci-Fi Apocalypse] [Interstellar War] [No System] In 2030, for reasons unknown, the Sun suddenly went dark, and the planets of the solar system began to fall apart one after another. The arrival of alien civilization, the Cosmic Overseers, brought hope for humanity's survival. But nothing comes for free. Humanity may have fallen into an even greater conspiracy: gathering minerals to send to the Cosmic Overseers, then trying to "draw" the supplies they provide to humanity. Whether this can truly be called a lottery is debatable. The protagonist, however, is no ordinary person. He has three years of space exploration experience from his previous life and a sound understanding of the various civilizations in the universe. With a few extraordinary guaranteed rewards beyond what ordinary people can expect, can he change his fate and his life by drawing again and again, and even change the fate of humanity?
