In the tenth year of Zhenguan, Empress Changsun passed away, and a soul from later generations became the prince of the Tang Dynasty, Li Chengqian, when time and space intersected. Faced with the destined destiny of being rebellious and deposed in the history books, he had no systematic blessing, only knowledge and patterns that transcended the times. He used the excuse of "receiving enlightenment from his mother in a dream" and started to solve the problem in subtle ways. When he finally stood in front of the Tai Chi Hall, what he opened was not only the continuation of Zhenguan, but also a more glorious new era - a prosperous Tang Dynasty reshaped by knowledge and hard work.
