I've Been Killing Slimes for 300 Years and Maxed Out My Level

Three centuries of slime‑slaughter finally unlocks a maxed‑out level, and the world comes knocking.

Azuma Aizawa spent her adult life chained to a corporate desk until burnout finally claimed her. In the afterlife, a whimsical goddess grants her an odd gift: eternal life in a low‑key fantasy realm where the biggest danger is a slime that barely registers on a monster manual. Embracing the quiet, Azuma settles on a modest farm, tending crops, defending a sleepy village, and slaying roughly two dozen slime blobs a day—an unremarkable grind that stretches across three centuries. One uneventful morning she discovers her experience bar has inexplicably maxed out at level 99, a feat no one could achieve without slaying dragons or conquering kingdoms. Panic‑stricken, she tries to keep the secret, but word spreads like wildfire. Soon a curious dragon named Laika, an aloof elf named Halkara, and a parade of other adventurers knock on her door, each drawn by the legend of the “Slime‑Killer.” As friendships blossom into a makeshift family, Azuma learns that even an immortal life can blossom when shared, turning her solitary routine into a surprisingly lively saga of camaraderie and unexpected heroics.
