Apocalypse Dragon Egg: Billion-Fold Return

In a post-apocalyptic wasteland, Chen Yu, whose genetic development is less than 1%, is abandoned by his family. On the verge of starving to death, he unexpectedly activates the "10,000x Gift Return System." A single egg is exchanged for an S-rank dragon egg; an old book brings a top-tier cultivation method; an ordinary weapon is upgraded into a divine armament. Relying on the system, he turns the tables, overwhelms genetically enhanced warriors, rises to prominence amidst mutant beast sieges and family oppression, and finally slaps down all who looked down on him with absolute power, embarking on the path of rise in the apocalypse.
