Tang Tingbai, a modern-day elite soldier, transmigrates into the useless crown prince of the Great Qian Empire. Bound to the King System, he gains Xiang Yu's power and the assistance of legendary heroes. He kills corrupt ministers, destroys powerful clans, and subdues rebellious princes before ascending the throne as Emperor Longwu. He subsequently conquers the Zheng and Jing kingdoms and brings the Great Wei and Great Zhou under his control, unifying the eight empires of the Northern Domain. Beneath the iron-fisted rule of this blood-soaked tyrant lies a benevolent heart that wants the people to live with full stomachs and warm clothes. When the system reveals that the continent also has eastern, southern, and western regions, an even greater journey is only just beginning.
