After I Transmigrated, the System Gave Me Only Mines, So I Handcrafted a Musket Battalion

A top student transmigrates to the frontier and activates the Divine Craftsman System. By completing missions, he obtains coordinates for iron ore deposits. When bandits threaten him, the protagonist draws on his knowledge as a materials science PhD to smelt steel with primitive methods and handcraft firearms. He forms the first ten-man firearm squad and wipes out the stronghold in one fell swoop, establishing a foothold in Qingshan Village.
