You are reincarnated in a dungeon, weird isn’t it? You don’t see anyone but a screen with a green orb on it, then you touched only to see 1/1 level, that dosent mean you can level up anymore…

You saw that your HP, MP, strength, defense and so on are at rank F, the weakest rank and when you thought hope is lost you saw that the only thing that is Level S is your loot drop on monsters.

By the way everything is dropped by monsters and if you ask anyone what thing doesn’t drop by monsters you don’t get an answer.
