This Adventurer Is Not Serious

Levi, who was reincarnated into a different world, gained the ability to become stronger by collecting monster materials. "A slime is worth two copper coins. You don't want to make a fortune from it, do you?" "Two copper coins? What a good thing?!" "A slime is worth two silver coins, boss, now we can really make a fortune!" "Two? Wait for me to tinker with it." "Boss, we found a piece of slime ahead." "Okay, I'll rush!" … When other adventurers are still worrying about skills, talents and job changes. Levi had already started, grinding monsters, grabbing materials, and bravely entering the dungeon.
