After Li Shimin, Taizong of the Tang Dynasty, died of illness in the 23rd year of Zhenguan, he actually traveled through time and became Liu Chan, who was only 16 years old during the Three Kingdoms period. Faced with the weak Shu Han, the dedicated Zhuge Liang, and the powerful heroes such as Cao Cao and Sun Quan, this eternal emperor was determined to assist Prime Minister Zhuge Liang to unify the world in the name of "Liu Chan".
He hides the wisdom and skills of an emperor, and skillfully mediates inside and outside the court: he is a "mediocre" young master on the surface, but secretly he promotes technological innovation, economic reform, and military reform. From improving the repeated crossbow to developing the prototype of gunpowder, from Dujiangyan water conservancy to Shu brocade being exported to the Western Regions, from secretly forming the "Xuanjia Guard" to surprise attacks on street pavilions... Li Shimin quietly changed the pattern of the Three Kingdoms.
When Zhuge Liang discovered that the young master "suddenly enlightened", when Zhao Yun and Jiang Wei sensed the young master's hidden imperial intentions, when Sima Yi realized that there was an invisible hand behind the Shu Han controlling the situation - the fate of the entire Three Kingdoms had already turned.
This is the joining hands of two generations of top wise men, the collision of the atmosphere of the prosperous Tang Dynasty and the situation of the Three Kingdoms, and it is also Li Shimin's epic journey to make up for the regrets of his previous life and restore peace to the world.
