In less than three years, the entire Yun County seemed to have been reborn. Small buildings rose from the ground, muddy dirt roads were transformed into flat and spacious concrete roads, and the faces of the people were filled with happy and enthusiastic smiles, and their mental outlook was completely renewed.

Qi Han felt the most about all these changes.

He was studying in the county school. He watched his hometown develop rapidly and heard his classmates praising Qi Sheng with mixed feelings.

After all, I can never compare to him.

And there is Yun Yuan, who was named Princess Nanjia by the emperor. If I had not married off, would I have contributed to her current achievements?

He tried hard not to think about it. In the second year that Qi Han was the county magistrate, he passed the imperial examination and was ranked third among the top three. After the imperial examination, he was assigned to be the county magistrate.

He secretly thought that although he was two years behind Qisheng, if Qisheng could do it, he could definitely do it too, and he would carry out a series of reform actions at the local level with high spirits and confidence.

Just when he was about to do something big, an imperial edict announced to the world made him dizzy.

Qi promoted him, no, Ximen Sheng, and he became the crown prince! Because of his achievements in governing Yun County, the court was convinced, and because he was the emperor's biological son, he was the rightful next emperor.

The emperor spent three years clearing the obstacles for Qi Sheng. Zhao Yu was dismissed from his post and his property was confiscated for privately minting copper coins and raising private soldiers. He was originally sentenced to death, but considering that the eldest princess had only this son, he could not escape the death penalty, so Zhao Yu was sentenced to life imprisonment.

However, King Ming acted cautiously, and it took the emperor two years to find evidence that he had committed a crime.

In order to cultivate his confidants, he framed loyal and honest people, participated in cheating in the imperial examinations more than once, and was also involved in a major case of selling illegal salt.

All the people who had been involved in this matter were questioned and he was demoted to a commoner.

Ximen Yao was implicated by him and became decadent at home, doing nothing all day long. This situation did not improve until Ximen Sheng came to power.

Yun Yuan served as queen for thirty years. She built schools across the country, popularized engineering, mathematics, and agricultural knowledge, and no longer confined herself to the Four Books and Five Classics. She cultivated batch after batch of talents.

Someone improved the spinning machine, someone made the bicycle, someone cultivated hybrid rice, and by the time she was about to leave, someone even invented the steam engine.

Technology is far ahead.
