Everyone Is a Hero, But This World Isn't Magical at All

Wu Shuang wakes up to find himself a Hero tasked with saving the kingdom. The catch? He is the 42,782,408,421st Hero. The previous one is lying right beside him, and they've been dead for quite some time. The system's first quest is to kill a goblin in town. It shouldn't be hard... except this particular goblin is massive—nearly twice his size. Fine, if that's what you want, I'll do it. It's just being a Hero, after all. But could you not have sent me to a proper magic world? Where's my invincible Hero's sword? Where's my princess? What?! There is a princess, but I have to dig her out of the ground myself? I @!#!$$!!
