Doomsday: Sorry, I Never Reload

[Ruthless and decisive, no saintly do-gooder + overwhelming firepower + mobile tank base] All fear comes from a lack of firepower, and I am the end of fear. The Abyssal Red Mist descended. Life mutated across the globe, and civilization collapsed. Survivors in the ruins sold their dignity for half a moldy loaf of bread and slaughtered one another for a single rusty bullet. Qin Lie was reborn one hour before the disaster began and awakened the [War Workshop System]. Any firearm he held came with unlimited ammunition, and he could even modify and enchant his weapons! While others counted bullets to make them last: Qin Lie switched his Glock 18C to full auto and turned a security door into a sieve. “Take it easy on the ammo? Sorry, the word ‘conserve’ isn't in my dictionary.” When a zombie horde surrounded a base and its defenses were on the verge of collapse: Qin Lie drove his modified heavy tank, the Tyrant, out of the mist. The M134 six-barrel Vulcan cannon on its roof spat out a three-meter dragon of fire. “Barrels get red-hot? Not a chance. I can hold the trigger down until the end of time.” When higher-dimensional beings descended and looked upon humanity as ants: Qin Lie hefted an endlessly charged portable nuclear cannon and smiled a benevolent smile. “Gods? Everyone's equal in my sights.” … From Glocks to Gatlings, from automatic grenade launchers to star destroyers. Qin Lie: “I have a severe fear of insufficient firepower, so carrying an entire arsenal around is perfectly logical, right?”
