A Foolish Son-in-Law? I’m the Emperor!

Li Chang'an transmigrates to ancient Ning, where he becomes an illegitimate son of the Li family and suffers endless contempt and bullying. Having lived two lives, how could he stand to live at someone else's mercy? Marrying into the Yun family is merely a stopgap. In Ning, he will carve out an empire of his own, command his own land and people, execute treacherous ministers and villains, and pacify the foreign powers of the Four Kingdoms. With literary talent like a startled swan and martial prowess like rolling thunder, he will rise to fame across the land. When he finally looks back, Ning has become a technological powerhouse!
