Urban Magic: My Wand Is a Glock 18!

[A protagonist’s background, a villain’s methods] [The villain bullies righteous characters without restraint because they’re kindhearted] [But I’m even more villainous than the villains] [Monster-slaying machine] [Battlefield meat grinder] Although Ji Bairen has only just started his first year of college, he has been transmigrated for many years and is already an old hand. He once heard someone say: When you’re out in the world! What matters isn’t going out there, it’s having power and connections! Ji Bairen, who has been quietly building up his strength for years, says, “I’m the mastermind behind a company!” Then someone says you need to have strength, too! Ji Bairen silently pulls out his exclusive wand: a Glock 18! Someone stubbornly retorts, “That only makes your magic fire faster!” Ji Bairen pulls out his big hand cannon, a Smith & Wesson M500! “High rate of fire in my right hand, high damage in my left. Got anything to say now?” Someone asks, “How are you so versatile?” Ji Bairen replies, “As long as you’re like me, with talent, a System, and half a wise old man living in your head... you can do it too!” The Starblue Continent. A continent where magic flourishes. After five world wars fought with magic, humanity takes the stage. Three great empires stand in a balance of power, seven kingdoms scheme for their own ends, and countless smaller nations struggle to survive between them. Those with magical talent awaken their [wands] at the age of six! Mages cast all kinds of magic using the wands they awaken! Mages who awaken [sword, blade, or hammer] wands become close-combat mages. Those who awaken [bows and crossbows] or [natural elements] become ranged mages. And those who awaken [wolf, bear, or leopard] wands, or even [dragon] wands... When Ji Bairen awakens a [firearm wand], he shows the magical world what simple, efficient, and utterly extreme killing looks like!
