Xiao Jingyan, a modern elite civil servant, once traveled through time and became the most unpopular ninth prince of the Yong Dynasty, who was thrown into the enemy country as a hostage. The day he returns home, he becomes cannon fodder for his royal brothers to fight for power. Faced with the desperate situation of powerful ministers in power, brotherly rivalry, powerful enemies outside, and an empty treasury, Jamel Xiao rose from the dust with the help of modern knowledge, extraordinary courage, and a little "system". He opened up sea trade, built a new army, promoted science and technology, took over poor families, and fought against the powerful. Step by step, he reorganized the broken mountains and rivers, and trampled under his feet all those who despised him and trampled on him. He wants these thousands of miles of mountains and rivers to be brought into the center; he wants the throne of the Nine-Fiveth Supreme Being, and it belongs to him!
