How I Became The World's Strongest Warrior By Using Basic Attacks Volume 5: A System Optimization LitRPG

By Kenny King

Chuck Taylor didn't ask to become the kingdom's strongest adventurer. But after soloing cosmic horrors, founding the fastest-growing guild in history, and crafting a sword that cuts through reality, he's used to unexpected upgrades.

So when Lucifer himself appears in Chuck's bedroom at 3AM offering a warzone full of boss-tier enemies and grindable soulstones, Chuck doesn't hesitate. XP is XP.

Welcome to Crowsfall, a nightmare city built from bone, where adventurers pay with trauma, vampires run breakfast joints, and every floor of the dungeon is ruled by a god of death or a demon of lies. Chuck's here to grind both factions.
But the soulstones aren't the only things stacking. Tensions rise. Faction pins evolve. Dungeon keys unlock. All to fight an enemy none of them are prepared to face. Yet.

The grind is back.
The numbers go up.
The enemies respawn.
And the grind has never been this good.
