Yu Wanqing was originally a graduate student in the Department of Modern History. She accidentally traveled through time while studying a jade pendant engaged by a young marshal of the Republic of China. When she woke up, she found that she was Yu Wanqing, the daughter of a merchant, and was forced to be engaged to the cold-faced marshal Chu Shaorong. The two reached a fake marriage agreement and each got what they wanted - she needed time to find a way to return to the future, while he needed a shield to deal with the family marriage.
However, as they get along, Yu Wanqing's modern thinking and Chu Shaorong's warlord style continue to collide. She used medical knowledge to treat plagues and used historical predictions to help him avoid political crises; while he was initially suspicious and monitored, but gradually became attracted to her intelligence and tenacity. The two faced conspiracy, betrayal and war together in troubled times, and their relationship gradually heated up.
When Yu Wanqing discovers the secret connection between the original owner and the revolutionary Cheng Lan, as well as the time-travel secret hidden in the jade pendant, she must make a choice between returning to the present and staying in the past. And Chu Shaorong also faces the ultimate test of family interests and personal emotions.
