During the Wude period of the Tang Dynasty, undercurrents were raging in the imperial city of Chang'an, and the struggle for the throne between the crown prince and the King of Qin had reached an endless stage.
Eight-year-old Li Chengqian, the eldest son of the Prince of Qin, lost his innocence after falling from his horse and woke up. With a foreknowledge of the direction of history, he stepped into this turbulent and turbulent situation of imperial strangulation.
At that time, Li Jiancheng pressed forward step by step, taking advantage of the Turkic war to seize the military power of the Prince of Qin's palace. Poisonous assassinations followed one after another. Li Shimin was forced into a desperate situation. If he was not careful, his whole family would be overthrown.
Li Chengqian used his childish body as a blade to pull out the coffin and mourn at the critical moment, and defeated the plot of the East Palace without any blood. At the Hongmen Banquet in the East Palace, he tested poison with his own body to block the deadly poisonous wine, and forcefully saved Li Shimin's life from the gate of hell.
From counter-killing the guard at Tongguan Station, to seizing the salt and iron franchise by taking advantage of the court's crisis, from weaving the Changfeng Intelligence Network all over the world, to building a military industrial fortress with advanced ideas, Li Chengqian stirred up the Tang Dynasty at the age of eight. Before the bloody shadow of the Xuanwu Gate fell, he rewrote the fate of his father and son step by step, transforming from a chess piece in the imperial chess game to a chess player who would determine the future of the Tang Dynasty.
