After the fall of the Emperor Zhenguan, Li Shimin, who was reborn in front of the Xuanwu Gate, witnessed the terrifying scene of the revival of spiritual energy, chaos of demons, and the collapse of the Tang Dynasty in the future. In this life, he transformed into a sinister emperor, used iron-blooded tactics to control the fate of the country, and secretly planned to fight against the drastic changes in the world. At the same time, a wisp of the Monkey King's soul also awakened in the body of the dying pawn "Shi Pan" in confusion, with all his magic power lost but still unruly. When the golden river of national luck, which symbolizes the imperial power and dragon energy, and the shadow of the golden cudgel, which hides the unyielding will, meet in troubled times, the two saints are forced to join forces due to suspicion and exploitation - the evil emperor wants to use the human dynasty as the basis to control the spiritual energy and reshape the order of the world; the reborn great saint vows to tear off the shackles of gods and Buddhas, regain freedom, and use war to clear the way. In this era of spiritual revival where gods and demons are whispering and undercurrents of the journey to the west are surging, a game between emperors and demons that concerns the survival of the human race and its own destiny is unfolding in blood, fire and intrigue.
