Duan An, a famous good-for-nothing prince in the Zhou Dynasty, spent all his time fighting cocks and lackeys, and was a mess in his studies. He was ridiculed as a "rotten tree" by the courtiers. One day, he accidentally awakened the "life exchange system" and was able to exchange bodies with various people in the capital. Today he is a scholar from a poor family, and tomorrow he is the son of a wealthy merchant. He can even experience the life of a powerful prime minister for a short time. However, every exchange is accompanied by the secret obstruction of a jealous villain-the emperor's brother Zhao Heng. Zhao Heng regarded Duan An as a thorn in his side and set up traps everywhere to destroy his reputation. In his identity changes one after another, Duan An not only used modern thinking to resolve countless crises, but also healed anxious beings around him with the open-minded mentality of a scumbag. From the streets to the Jinluan Palace, Duan An gradually understood the way of governing the country in his daily life that made people laugh and cry, and finally won the hearts of the people with his unique "student wisdom", making the jealous feel ashamed, and created a different kind of legend of the prosperous age.
