Changed Profession as Gunsmith, I Became the White Moonlight Spell Turret

In the era of job transfer for all people, monsters are raging and secret realms are rampant. Lu Chen changed his profession and became a recognized "sewer profession" - gunsmith. This kind of profession involves scraping in the early stage and burning money in the later stage. It is ridiculed by countless people as "a toy of the rich second generation" and "a symbol of the prodigal son". Even if there was a top-notch "valkyrie" sister in the family who was willing to support him, everyone thought Lu Chen was useless. Until Lu Chen awakened the SSS-level talent [Source of Elements·Authority]! [Magic Arsenal]: MP is ammunition, and the rate of fire is the casting speed! [Intelligence Dominator]: Power? Agile? The dogs don't even order! I have all my intelligence! As a result, the style of painting changed: While other gunsmiths were carefully planning to buy bullets, Lu Chen was wearing a blue suit, holding a Gatling gun, and was clearing the ground with three thousand explosive fireballs per second! While other mages were chanting forbidden spells, Lu Chen took out his sniper rifle and fired a bullet enchanted with the "Nine Heavens Divine Thunder", knocking down the BOSS from eight hundred miles away! Fiancée Su Qingge pushed up her glasses: "According to calculations, the output per second of Lu Chen's pistol just now is equivalent to three full mage regiments." My sister Lu Ya carries a giant sword and doubts life: "As promised, I will be responsible for making money to support the family, and you will be responsible for looking beautiful? Why did you defeat the BOSS?" Lu Chen: "Don't ask, just ask: caliber is justice, range is truth!"
