The Divine Weapons Manor's Son-in-Law: From the Start, I Handcrafted an AK-47

(Also known as Let Me Build Divine Weapons, and You Pull Out an AK? and I, the Arms Dealer of the Martial World)

Wei Yuan transmigrates into another world and becomes the useless live-in son-in-law of the Divine Weapon Manor, stuck with an icy fiancée who looks down on him.

But he doesn't care. Cultivation is exhausting. Wouldn't it be better to lie flat, tinker with machinery, and live as an easygoing nobody?

That is, until one day his nemesis comes to provoke him, crushes his beloved model, and orders him to kneel and bark like a dog.

Wei Yuan snaps.

“I just want to be useless. Why do you insist on pushing me?”

[Ding! The Host's intense will to resist has been detected. The Military Industry System is activating!]

Reward from the start: blueprints for an AK-47!

From then on, the Divine Weapon Manor has an eccentric son-in-law.

While his fellow disciples sweat through their sword practice, Wei Yuan tinkers in a corner with a pile of “scrap metal” no one can make sense of.

Tang Lianxue: “Wei Yuan, you're wasting your time on these useless tricks again!”

Without looking up, Wei Yuan replies, “Quiet. I'm studying rifling. It determines whether my ‘divine weapon’ can take out that Demonic Cult leader with one shot from four hundred kilometers away.”

Tang Lianxue: “???”

When the Heavenly Craft Workshop arrives to show off its newly forged sword, Wei Yuan slowly carries a six-barreled Gatling gun out of his workshop.

“I hear your swords are fast. Sorry, this thing fires sixty rounds a second. The martial world calls it the Gatling Bodhisattva. It can handle anyone who refuses to behave.”

The whole martial world is stunned! Weren't we talking about divine weapons? What is that fire-spitting thing?

Wei Yuan spreads his hands helplessly. “Can't be helped. You shouldn't have picked a fight with a tech nerd who just wanted to lie flat.”
