Class Change: Gunner by Trade, White Moonlight Spell Artillery by Heart

In the age of universal class changes, demons run rampant and secret realms are everywhere. Lu Chen changes class into the universally mocked “bottom-tier class”: the Gunsmith. This class is weak early on and expensive later, mocked by countless people as “a rich kid’s toy” and “the mark of a spendthrift.” Even though his Valkyrie older sister, a top-tier siscon, is willing to bankroll him, everyone still thinks Lu Chen is a lost cause.

Agility? Not even a dog would put points into those! I’m putting everything into Intellect! And so, everything changes: While other Gunsmiths carefully budget for bullets, Lu Chen, dressed head to toe in mana-regeneration gear, wields a Gatling gun and carpets the ground with three thousand explosive Fireballs per second! While other mages struggle through chants to cast forbidden spells, Lu Chen pulls out a sniper rifle and blasts a boss to smithereens from four hundred kilometers away with a bullet enchanted with “Heavenly Thunder”! His fiancée, Su Qingge, adjusts her glasses. “By my calculations, the pistol Lu Chen just fired deals as much damage per second as three full mage regiments.” His sister, Lu Ya, hefts her greatsword, questioning her life choices. “Weren’t I supposed to earn money for the family while you just had to look pretty? How come you’re the one one-shotting every boss?” Lu Chen: “Don’t ask. The answer is that caliber is justice, and range is truth!”
