Li Yi's soul transformed into a full-level emperor of the Great Sage Dynasty, integrating imperial power, military power, and political power. However, he encountered a series of evil behaviors such as the queen asking for the tiger talisman, the concubine forcing the official to be appointed, and the queen mother plotting to poison her. He abandoned the character of his former master as an infatuated dog-licker, used iron and blood to quell internal troubles, and killed the rebel members. At the same time, the king outside Guan launched an army to take revenge. He relied on the 200,000 imperial guards led by Guan Yu's descendants to defeat the enemy. In the end, facing the enemy who controlled the Ultraman mecha after resurrection, the old eunuch who concealed his identity came to help. After clearing all crises, Li Yiling gave up the throne and followed the old eunuch on the road to immortality, starting a new journey.
