Global: Failed Enhancement? I Get a Hundredfold Critical Return!

Jiang Chen transmigrates to a world where everyone changes class, but becomes a laughingstock after awakening two useless classes. What no one knows is that he also awakened a god-tier Enhancement System. It has no limit on the number of enhancements, nothing ever breaks, and even failed enhancements can return up to ten thousand times the materials! Jiang Chen has a blast with it. He takes a level-10 short sword that everyone else considers trash and enhances it tens of thousands of times, adding dozens of skill effects. A casual swing is enough to destroy heaven and earth!
