When Chen Lan, a graduate student in the Department of Modern History, touched an oracle bone with strange patterns in the Yin Ruins Museum, he was suddenly drawn into the vortex of time and space. When he opened his eyes, he was in the Xiqi wilderness in the late Shang Dynasty and early Zhou Dynasty. Dressed in rags and speaking in a different language, she was accidentally rescued by Jichang, the Marquis of Xibo who was passing by.
At that time, Ji Chang was not King Wen of Zhou, and he was governing Xiqi with benevolence. However, because of his growing reputation, he was jealous of the King of Shang. With the historical knowledge in his mind, Chen Lan could not only put forward suggestions for improvement in farming, but also secretly give Ji Chang solutions to resolve difficulties when he encountered difficulties. During the seven years when he was imprisoned in Youli, Chen Lan used the tenacity and wisdom of modern women to help Boyikao and Ji Fa maintain the hearts of Xiqi.
She knew Ji Chang's fate and understood the necessity of Zhou's family acting as a merchant, but as they spent time together, she fell in love with this gentleman who had the world in mind. Ji Chang was also moved by Chen Lan's intelligence, courage and gentleness that were very different from the times, and regarded her as the only solace in troubled times. But the gap between time and space, the great wheel of history, and the bloody changes of Shang and Zhou dynasties have constantly torn apart this love that spans three thousand years. They have to work together to deal with the conspiracy of the Shang court and the games of the princes, and Chen Lan has to face an ultimate problem: should he adapt to history and be a bystander, or should he risk everything to rewrite the known fate in order to protect his lover?
