The Stormy Xia Dynasty

History graduate student Lin Yuan unexpectedly transmigrates to the fictional Great Xia Dynasty, becoming a poor scholar with nothing but the walls of his home. Using modern knowledge, he starts by improving papermaking and organizing disease prevention and disaster relief, then outwits corrupt officials and establishes a merchants' guild, surviving and growing stronger in troubled times through his overwhelming advantage in knowledge. After passing the imperial exams and entering government, he refuses to take sides in factional struggles and instead chooses a post in the border city of Yunshan. There, with practical measures, he reforms border defenses, improves people's livelihoods, and opens up border trade, putting his ideals of "breaking deadlocks with knowledge and building a nation through institutions" into practice amid the flames of war. Facing court conspiracies, aristocratic clan infighting, and foreign invasions, Lin Yuan advances cautiously with reason and wisdom, driving gradual reforms and ultimately becoming a pivotal force in changing the course of the age.
