The Exiled Smelter's Revenge

Cedric Lowe, a top modern National Scholar of metallurgy, transmigrates into the legitimate heir of the Lu family, framed by the secondary branch and exiled to the Black Rock Depleted Mine. Leveraging his metallurgy and military industry expertise, he forges powerful weapons, recruits mine slaves and deserters, repels sieges, fortifies the stronghold, and waits to take revenge on Lu Huaizhang and clear his family of false treason charges.
