Li Xu traveled through time and became the deposed prince of the Yan Dynasty. He was forcibly sent to the fiefdom before he even opened his eyes. Looking at the impoverished fiefdom, the equally impoverished King Shun could only roll up his sleeves and work hard to make a fortune with the people of the fiefdom.
A few years later, Prince Shun brought his family to Beijing in a low-key manner, and everyone in the capital was waiting to see his joke. It turned out that he was eating dishes cooked by Prince Shun's chef, wearing clothes designed by Prince Shun, using daily necessities produced by Prince Shun's house, living in a house built by Prince Shun's craftsmen, and even going out had to step on the cement road built by Prince Shun's mansion. No one dared to offend his parents.
