Zhao Chun accidentally traveled through the Tang Dynasty and became acquainted with Princess Changle due to a "dudou incident". The punishment of the imperial staff was full of dangers, and the system cards helped him escape from death. He won the favor of emperors and empresses by presenting poems handed down from generation to generation, found rice seeds in Zhancheng to solve the food shortage of the Tang Dynasty, and brewed strong wine to make the founding heroes drunk. From an unknown scholar to the uncle of Ankang County, from a prisoner to a quasi-consort, an adventure spanning time and space composes a passionate legend of the Zhenguan period.
