Zhang Yun, a doctor of modern agriculture, was accidentally electrocuted in the laboratory. When he woke up, he found that he had traveled back to the eighth year of Zhenguan in the Tang Dynasty and was possessed by Zhang Yun, a down-and-out scholar with the same name. He was in Zhangjia Village on the outskirts of Chang'an.
Through memory fusion, he learned that he had a wife, Liu Waner, whom he was married to but not yet married to. She was the daughter of the Liu family in a neighboring village. Due to the financial difficulties of the Zhang family, the marriage was put on hold.
Zhang Yun first met Liu Waner who came to deliver wild vegetables. He was amazed by her elegant and refined temperament and decided to take on the responsibility of taking care of this "fiancée"
Faced with the poor situation of his family, Zhang Yun used modern knowledge to improve the farm tools at home, which aroused the curiosity of the villagers and the surprise of Liu Waner.
