Special Forces doctor Yun Xi traveled through time to a fleeing princess of Nanzhao because of her ancestral jade pendant.
The original owner was on a mission to go to the capital of Xiliang Kingdom to find help and return to the Nanzhao Kingdom to rescue the Queen's mother. Unwilling to leave, her soul fell into Yunxi's Yuperi.
In order to have a chance to return to modern times, Yunxi promised to fulfill the original owner's wish, and started on the road to help seize power in the daughter country as the princess of Nanzhao.
On the road to restoration of the country, he was assassinated, ambushed, and framed. There was always someone who appeared in time, allowing Yunxi to save the day.
Kang Junnan, the dignified and cold-faced prince of Xiliang Kingdom, said affectionately to Yunxi, "Xier, marry me! I promise you to be together for the rest of your life. How about it?"
Yunxi saw Kang Junnan take out a cloth bag from his arms, and when he opened it, it turned out to be a modern high school mathematics textbook.
"You, you, you... You are also a time traveler from modern times!!" Yunxi opened his eyes wide and said in great surprise.
