I Alone Wield Magic, and My Second Uncle Is Uncle Jiu

Trapped in a county town, with everything stacked against him from the start. Orphaned and alone, Xu Yang depends on his mentally ill second uncle, who spends all day claiming to be Uncle Jiu. In his eyes, the world is full of hundred-year-old cat demons, thousand-year-old flying corpses, and the dreaded Renjia Town... He even tells Xu Yang to join him in vanquishing demons and defending the Dao, swearing to wipe out every monster under heaven. To help his uncle recover as quickly as possible, Xu Yang naturally agrees without hesitation. And then... You've got to be kidding me. What the hell is this Demon-Slaying and Dao-Defending System? I'm not even in a supernatural horror world! So the stray cats are cat demons? The serial burglar in the neighborhood is a thousand-year-old flying corpse? And the old East Gate district is the legendary Renjia Town? From then on, through one bizarre misunderstanding after another, Xu Yang rises against all odds, becoming an academic heavyweight with billions to his name, the one and only practitioner of the Dao! But can someone please tell me: if swordsmanship with peachwood swords can pass for a martial art, then what good are exorcism spells in this peaceful, thoroughly materialist world, huh?
