The blood of Xuanwu Sect has not yet dried up, and the power whirlpool of the Tang Dynasty is surging again. King Li Yuanji of Qi was unexpectedly reborn. He knew that he could not escape his fate and was determined to change the tragic ending of his execution. Faced with the pressing pressure of Prince Li Jiancheng and the brilliant strategy of King Qin Li Shimin, he trudged forward on the thorny road of power and conspiracy. From the secret plot in Chencang in the Battle of Youzhou to the verbal confrontation in the court, murderous intent was hidden in every step.
Two hundred thousand Turkic cavalry pressed down on the border, becoming a key bargaining chip in the game between the three brothers. Li Jiancheng tried to use the help of foreign enemies to eradicate his dissidents, but his collusion with the Turks was revealed, and he fell from the position of prince. Li Shimin led the Xuanjia Army to fight bravely in Youzhou, and with the help of Luo Yi, he reversed the battle. He made great achievements but was jealous of his brothers; Li Yuanji was ambitious and wandered among various forces, waiting for opportunities.
Inside and outside the court, Fang Moudu's resourcefulness and Wei Zheng's uprightness were intertwined into an intricate web of power and intrigue. Forces from all sides are fighting openly and secretly, the prince's remnant party is ready to make a move, and a wave of public opinion is sweeping across Chang'an. In this life-and-death power struggle, who can clear away the fog of history and ascend to the supreme throne? Who will become the key figure in rewriting the fate of the Tang Dynasty in the turbulent changes?
