Ji Yuqing, a white-bone spirit in the modern city, unexpectedly got into a plane crash and somersaulted down. He unexpectedly traveled through time and space and landed in the Zhao State at the end of the Warring States Period. He met Qin Shihuang Ying Zheng, who was only a seven-year-old kid, and the same kid - his good brother - turned out to be Prince Dan of the Yan Kingdom. They regarded her as a fairy sister who flew from the sky. She was named Yu Ji and lived in the proton hall of Zhao State.
Ji Yuqing, who traveled through time, has a body that is not controlled by ancient time, and a face that can last forever, but she encounters embarrassing emotional problems. Ying Zheng and Prince Dan, who were once brats, have grown into handsome men, and it seems that they can't help but fall in love with this sister who flew from the sky.
In the chaotic history of the late Warring States period, she met and became acquainted with Jing Ke, Lord Xinling of Wei, King Ying Zheng of Qin, and Prince Dan, but she was destined to pass them by.
She was just a passerby in this ancient time and space?
How to put an end to this love and hatred that is unclear and chaotic?
Ying Zheng: I will love you forever.
Yuqing: But how did he know that I have loved him for more than two thousand years!
