Super gene with 100x return

In the desolate future of Blue Star, humanity clings to survival against monstrous alien creatures after portals to the 'Sanctuary' shattered reality. Han Yuan, a cheerful but deeply insecure orphan, dreams of escaping his mundane life and finding belonging. But fate grants him more than just an escape; a mysterious '100x Return System' embeds itself within his soul. Every gene he acquires, every skill he masters, every resource he expends, multiplies exponentially. This cheat propels him into the ranks of the elite, but also into the crosshairs of ancient powers vying for control over the Sanctuary's secrets. Han Yuan must not only master his absurd power but also navigate a world where his every gain makes him a target, all while confronting the gnawing fear that his worth is solely tied to his system-given abilities, not himself.
