Ilia

I forgot what it was called but it was about a guy who was a player(?) that got stuck in the demon realm(?) or hell, idk, and had to fight demons or monsters to survive until he reached a max level. And he thought he'd be able to get out once he reached the maxed level but he couldn't but for some reason he was able to find a way out and he spawned in a dungeon and there was a lizard and the last thing i remember is a red long haired femboy who was a dragon yeah

its called The Law of Immutability
