In the apocalypse, my weapons can evolve infinitely.

The apocalypse has arrived, zombies roam freely, order has collapsed, and despair blankets the land. The protagonist, Jiang Xun, betrayed by his lover and oppressed by villains, unexpectedly becomes bound to the [Apocalypse Weapon System] when he is on the verge of despair. From an ordinary slingshot to an armor-piercing bow, from steel nails to energy marbles, he fights his way through, evolving with each blow. Wherever his arrows point, nothing can stop him. With the most desperate start, he sweeps across the apocalypse, ascending to the throne of the wasteland's king.
