In the tenth year of Zhenguan, Empress Zhangsun passed away. At the crossroads of time, a soul from a later age became Li Chengqian, crown prince of the Tang dynasty. Faced with the fixed fate recorded in the history books, that he would be deposed for treason, he had no System to help him, only knowledge and vision far beyond his time. Claiming that his late mother had enlightened him in a dream, he began to turn things around one small step at a time. By the time he stood before the Taiji Palace, he had set in motion more than the continuation of Zhenguan. He had ushered in a more glorious new era, a golden age for the Tang reshaped by knowledge and practical action.
