My Divine Weapon Is Actually an Upgradeable Beauty

One day in the future, a sudden meteor shower shatters humanity's peaceful existence. Countless portals to secret realms appear across the world, and all manner of ferocious beasts pour through them, attacking human cities. Humanity cannot simply sit back and wait for the end.

The mysterious meteor shower brings disaster, but it also bestows upon the world the materials needed to forge divine artifacts. Before long, all kinds of divine artifacts emerge. Armed with them, humanity battles the beasts and closes one portal after another.

Those hailed as heroes are known as Hunters. Zhang Xiaoyao, a good-for-nothing office drone, accidentally gains the ability to fight back against the secret realms. But his power seems different: he can see a System that no one else can, and he also has a unique feature that lets him upgrade his divine artifact.

Most importantly, his divine artifact is a beautiful girl!
