{Shen Yan}, a graduate student in the Department of Modern History, accidentally traveled to an ordinary village outside the city of Chang'an in the prosperous Tang Dynasty. He was bound to the "Knowledge System" and needed to upgrade by exploring ancient knowledge and solving the mysteries around him.
He worked step by step, while learning ancient farming and folklore knowledge to complete systematic tasks, while at the same time detecting anomalies in the village - the missing villagers, the greedy prying eyes of the neighbor Liu family, and the strange whereabouts of the rebellious son of the squire Li family, all hidden secrets.
The gentle village girl Su Wanqing helped him many times and became his comfort in another world. However, she also became involved in deeper entanglements with him because of her family's stance. As the system is upgraded, Shen Yan discovers that the mystery of the village is actually related to the Chang'an court. He must balance the pursuit of knowledge and survival, and survive in the chess game of the prosperous Tang Dynasty as a mortal.
