Global Class Change: I Level Up by Devouring

For humanity to have a future, everyone had to keep leveling up and growing stronger, defeating every alien race before peace could come.

Devour the corpses of ordinary creatures to gain massive amounts of experience and attribute points. Devour the corpses of class users to gain their exclusive skills. Devour a BOSS's corpse to increase your class rank. And so a multi-class user was born, wielding an array of SSS-rank skills as a mage, warrior, elf emissary, Thunder God, and more. “Before the battle begins, let me put a few buffs on myself.” “[Earth Shield], [Full of Energy], [Infinite Mana], [Lucky Critical Hit], [Doll of Substitution], [Strength Absorption], [Flames of Hell], [Ice Dragon's Blessing], [Domain of the King]...” As Su Yi used more and more outrageous skills, the colossal beasts blotting out the sky and the ruthless alien invaders all dropped their weapons and asked themselves a soul-searching question: “So, if we run now, is there still time?”
