First of all, I would like to apologize. Due to the changing of character names and poor memory, there will be inconsistencies in the characters. Background of the era: During the Zhenguan period, the Tang Dynasty's national power was booming, but there were still internal and external troubles. The internal heroes are arrogant and the struggle for the throne of the prince is emerging; the external Turkic threat has not been eliminated, and the countries in the Western Regions are waiting and watching. Protagonist: Li Ke: The male protagonist, about 18 years old, is a college student in the Department of Modern History, especially obsessed with Emperor Taizong of the Tang Dynasty. His personality is a bit off-kilter, but he is principled and quick-witted at critical moments. Li Shimin: About 35 years old, Emperor Taizong of Tang Dynasty. Talented and thoughtful, he has the majesty of an emperor and complex emotions for his children. At first he felt strange and wary of his "lost and found" son, but later he was gradually attracted and trusted by his unique words, deeds and "vision". Core conflict: How did Li Ke use modern knowledge and historical perspective to survive in the Tang Dynasty and adapt to the status of "prince" without revealing his identity as a time traveler.
