Champion Marquis of Great Xia, Cast Aside by the Duke's Household from the Start

[Alternate history + conquest + ancient-era farming + God of War] After transmigrating to the Great Xia Dynasty, Lin Yuan finds the Rongdi invading. He has no choice but to don his armor, take up his silver spear, and defend his homeland. He wins countless military honors, then fakes his death to escape. But his fiancée mistakes him for a coward afraid of dying and insists on divorcing him! Fine, let’s divorce. A great man has no shortage of potential wives! He casually writes a poem that countless scholars rush to recite, and a Grand Academician hails him as the face of Great Xia’s literary world. He leads the army into battle, wipes out the Rongdi barbarians, and ends the century-old border crisis plaguing Great Xia. He invents glass, refined salt, and brewing, and wealth pours in from every direction. Great Xia’s princess: Father, I want Lin Yuan to be my husband! His former fiancée outside the Duke’s estate: I thought we were best friends, and you’re playing mind games with me?
