How My Useless System Made Me OP

Zevian's life as a convenience store clerk was a joke. His death? Even more pathetic. But when he transmigrated into a brutal fantasy world, it seemed like luck had finally turned: he awakened a System! Just one problem: this System seemed more interested in trolling him. Quests like 'Pet 3 Grumpy Cats' or 'Find a Potato That Looks Like a Celebrity'? Rewards like the 'Used Sock of Indifference' and the title 'Level 1 Instant Noodle Chef'? What kind of cosmic prank was this? While other adventurers got legendary swords, Zevian got... an erratically bouncing rubber duck. But where the System saw trash, Zevian's genius, obsessively pragmatic mind saw potential. With flawless logic and an absurd ability to analyze the useless, he began turning the System's 'pranks' into raw power. The Used Sock? Absolute defense against tickle attacks (and maybe something more?). The Rubber Duck? An unpredictable projectile weapon that baffles even seasoned mages. The meme quests? Sources of crucial information or triggers for unexpected events only he can foresee and exploit. In this world, Zevian doesn't walk the hero's path. He walks the path of maximum efficiency, using the System's 'trolling' as his greatest weapon. He'll prove that no matter how trollish your guide, an SSS-rank brain can turn any junk into treasure capable of shaking the heavens. Get ready to see trash become treasure, and the punchline become the biggest threat this world has ever seen!
