A top student in modern history suddenly became the prince Li Jiancheng two years before the Xuanwu Gate Incident - the man who was labeled a "loser" by history books.
Knowing his fate two years later, he would never make the same mistake again. Faced with the various conspiracies surrounded by Li Shimin, he used modern knowledge as an edge and advanced strategies as a shield to dismantle the series of conspiracies step by step, forcibly tore a way out of the established ending, and firmly established his position as the crown prince.
In the end, he reversed the bloodshed of Xuanwu Sect and ascended the throne and proclaimed himself emperor. Then, with a vision far ahead of the times, he reorganized the government, prospered the country, and benefited the people, making the glory of the Tang Dynasty shine even more dazzlingly in his hands.
