Becoming a God by Slaying Slimes

Lu Xien transmigrates to another world, becoming a mage apprentice exploring a dungeon. The moment he kills a slime, he awakens the one and only Origin-tier talent: [Path of the Hero King]. Slaying monsters lets him gain attribute points and skills. Everyone thinks he's simply terrifyingly strong. That is, until someone notices his status screen, where the skill list is crammed full of abilities. Someone from the guild asks him, “Just what class are you?” Lu Xien thinks for a moment. “All of them.” The Path of the Hero King has no limits and no bottlenecks. As long as he keeps killing monsters, he can grow stronger! Only at the very end does Lu Xien understand just how heavy the burden of being the Hero King is. [Otherworld] [Dungeon] [Mage]
