Frontier Empire: Rise of the Han Borderlands

A modern soul transmigrates into Gongsun Du at the end of the Han dynasty, facing a dead end from the start. In the golden hall, he cleverly uses 'heavenly auspicious signs' to fight for a chance to survive, and stakes his entire clan's life on a military pledge to seek a way home. After returning home, he promotes land reclamation, rectifies governance, and trains elite troops. He attacks the Xianbei in the north, destroys Goguryeo in the east, and pacifies the Three Han in the south. While the central plains warlords are locked in endless conflict, he has already built a powerful empire with ample troops and supplies on the northern frontier!
