The Prince Married Into a Barbarian Clan for Three Years, Then I Marched on the Capital With the Empress

Li Yu, Dragon Lord and Divine General of the Great Xia Dynasty, died with his name cleared too late. His soul transmigrated to a parallel world, where he became the good-for-nothing, illegitimate sixth prince of the Great Li Dynasty. Blood was already being spilled in the palace from the start. Who has time for palace intrigue and political maneuvering? Military power... The world... Whatever I, Li Yu, want is mine for the taking! Princess Be mang, weren't you the one who wanted me to marry into your family? Why are you clinging to my leg and refusing to let me go now?
