After Li Yi traveled through time, he found himself outside Chang'an City. Relying on his knowledge of history, he successfully sneaked into the city, and by chance met Li Shimin, who was visiting privately incognito. Li Yi's talent and knowledge caught Li Shimin's attention and he was called into the palace.
Li Yi was well aware of some of the problems that the Tang Dynasty was about to face, and he proposed a series of reform suggestions to Li Shimin, including improving agricultural technology, developing commerce, and reforming the imperial examination. Li Shimin was dubious about his suggestion, but decided to try to implement it partially.
In the process of implementing reforms, Li Yi encountered numerous obstacles and frame-ups from conservative forces. However, with his wisdom and courage, he saved the day time and time again.
Li Yi also made some like-minded friends, and they worked together for the prosperity of the Tang Dynasty. At the same time, Li Yi fell in love with a Tang Dynasty woman.
As time went by, Li Yi's reforms achieved remarkable results, and the Tang Dynasty's national power became increasingly powerful. But he also realized that his existence might change the course of history.
