The soul traveled through Zhenguan and became the three-year-old son Li Xiang of Prince Li Chengqian. It coincided with the death of Empress Changsun and the undercurrent of the struggle for the throne. Looking at his father, who was destined to rebel and be deposed, and his uncle, Changsun Wuji, who would be ruined in the future, he was shocked late at night with his baby teeth in his eyes to realize that all the wind and rain were filled with sharp knives hanging from his neck. Everyone knows that children are ignorant, but he was able to improve farming on the back of Zhenguan politicians, and dared to pull Li Shimin's dragon robe to warn him in a childish voice. From disrupting the prince's chess game to rewriting the fate of powerful ministers, his immature hands quietly grasped the pulse of the court, causing the direction of the prosperous Zhenguan era to deviate. Let's see how a modern soul can survive step by step in the bloody storm with a three-year-old body, and become the master behind the scenes of the Tang Dynasty for hundreds of years!
