Time travel prince Zhao Ding guarded Youzhou for eight years. On the surface, he complained about poverty every year and defrauded the court of money and food. In fact, he relied on modern technology to develop agriculture and business, make firearms, and turn a barren border town into a rich treasure land. The emperor made secret visits and was serially ripped off. He saw through his son's disguise but secretly fell in love with his talent. During this period, Zhao Ding defeated Nanchen's invasion and captured the Princess of Beiliang, and the two secretly fell in love. The crown prince in the capital was still young, and there was an undercurrent in the court. The emperor wanted to change the crown prince, so he falsely claimed that the queen was seriously ill and ordered to summon Zhao back to the capital.
