Modern engineer Lin Yuan accidentally travels back to the Great Xia Dynasty and becomes the most despised son-in-law of the General's Mansion—despised by his wife Su Wan and mocked as a "good-for-nothing" by servants. When the Northern Rong cavalry invades and Great Xia is helpless, Lin uses his modern knowledge: he takes out an improved gunpowder formula and builds a repeating crossbow, destroying the enemy's grain camp overnight. Returning in armor with victory, Su Wan's contempt turns to admiration, and those who once laughed at him kneel, calling him "Prince"—the discarded son-in-law has risen with modern technology.
