Traveling through time and becoming the last puppet emperor of Daxia, Xia Ji, it was the 798th year since the founding of Daxia, and it was on the verge of a catastrophe for the country's destiny in the 800th year. The seven vassal kings, Ying Zheng, Li Yuan, Genghis Khan, etc., Were all watching with eager eyes, each harboring the intention of usurping and rebellious. The civil and military officials in the court are all the vassal king's spies. In the harem, Wu Zetian, Zhao Min, and Jiang Yuyan are hiding in the city. There is even a prodigal queen mother who empties the treasury and controls the palace power, hoping to push Daxia into the abyss. In a desperate situation, Xia Ji awakened the National Destiny Summoning System and offered three summoning opportunities at the beginning. He summoned Han Xuan, the ruthless cat, to sit beside him and learned the "Fudo Ming King Body". Let's watch him use the power of the system to kill the queen mother, suppress powerful ministers, suppress the vassal king, sweep away the harem heroes, defy the will of heaven and save the Great Xia from decline, and take charge of the 800-year-old imperial dynasty!
