Eight modern high school students accidentally activated the time shuttle and traveled to 615 AD (the last year of the Sui Dynasty). They played an extremely important role in the struggle for hegemony between the Sui and Tang Dynasties. Each of them had an identity in ancient times. They were Li Jiancheng, Li Shimin, Li Xiuning, Chai Shao, Shi Feixuan, Song Yuzhi, Kou Zhong, Xu Ziling, and Wanwan in that life. They survived strongly in the struggle for national power and martial arts and completed their mission in this life. Zhong Yudi, who became Li Xiuning, is familiar with the history of the Sui and Tang Dynasties. She does not want the people around her to lose their happiness and life because of the fate of history, but she fails in the struggles again and again. Are they writing history, or is history at the mercy of them? In the final Xuanwu Gate incident, what will be the fate of the person she loves deeply?
Love is an eternal proposition. Love is belief, love is fulfillment, love is hope, love is memory. Traveling through time and space and experiencing all kinds of difficulties, I finally met you in this life and my eternal true love.
