The End of the World: I Can Buy Unlimited Magical Equipment

The end of the world is coming and the world has fallen. Others had to risk their lives to grab even a rusty machete, but I casually swiped it - and the orange magic dress fell from the sky! The zombie king came to the city, and the survivors were desperate and waiting for death. I took out the level 99 dragon-slaying armor with my backhand and cleared the screen with one knife. As a result, the next second, I threw the artifact into the recycle bin... The system prompted: Host, that is the top equipment of the current version. Me: Oh, then just brush ten more and use them as toys. Later, there were so many magical costumes that they covered the entire city. The boss knelt down and begged me to do it for him. The zombies turned around and ran away when they saw me. I was also helpless - I was just an ordinary spawner monster, how could I become the savior of the apocalypse?
