Hu Yufei, a student in the Department of Archeology, accidentally touched an ancient jade engraved with strange patterns in the research institute, and suddenly fell into the Qin Dynasty BC. The chaotic world and unfamiliar rules made it difficult for him to move forward, but during his escape, he met Yang Lingxi, a woman who carried family secrets. She is cold and intelligent, and seems to be hiding secrets related to ancient jade. In order to survive, Hu Yufei relied on sporadic historical knowledge to deal with various forces - he witnessed the domineering power of "Chu Feng" and the forbearance of "Liu Jun", and was also involved in the conspiracy of "Eunuch Zhao" in the palace. His relationship with Yang Lingxi sprouted in troubled times, but was repeatedly tested due to the barriers of identity, stance and even time and space. When the wheel of history drove towards the whirlpool of the conflict between Chu and Han, Hu Yufei discovered that the ancient jade in his hand was the key connecting two time and space, and Yang Lingxi's fate was closely related to the fall of the Qin Dynasty. Will he adapt to history and be a bystander, or will he risk everything to achieve a different outcome for his lover and ideals? An adventure and love spanning a thousand years slowly unfolded on the Qin Ruins.
