In most fantasy worlds, a Demon King invades using terrifying magic, catastrophic ancient curses, or an overwhelming army of dark monsters.

But I became a Demon King who handles things a bit... differently.

Realizing that fighting humanity's powerful heroes and brilliant mages head-on is a waste of resources, I decided to weaponize the ultimate, unstoppable force: absolute anti-intellectualism. Why bother trading blows with high-tier magic circles when I can just spread misinformation, lower the world's overall IQ, disrupt the academic system, and make critical thinking completely obsolete? As my dark influence spreads, humanity's greatest empires begin collapsing from within due to sheer stupidity, logic fails, and ridiculous conspiracy theories. Armed with a system that fuels my power the more chaotic and brainless the world becomes, my modern-minded, chaotic invasion is about to prove that a world without brains is much easier to conquer than a world without walls.
