The Greatest Emperor of the Great Zhou

He transmigrates to ancient times and becomes the emperor. From the start, he has neither power nor influence. He's just a useless ruler. To make matters worse, the nation is in decline, the people are destitute, and enemy armies are massing at the border. Corrupt officials run the court, and powerful ministers hold sway. Li Zhengyang says these are all minor problems. I'm the emperor. It's perfectly normal for me to confiscate a family's wealth and behead someone, right?
