This work tells the story of a tower guardian who had no intention of competing for hegemony, but was forcibly "married" by the last emperor who was on the verge of desperation and had a blood feud, and was forced to be involved in imperial intrigues and continental disputes. The highlight is that the male protagonist is not a useless counterattack. He has no talent for cultivation from the beginning to the end. Instead, he relies on the profound knowledge obtained from the Guardian Tower, the mind and insight far beyond ordinary people, and becomes the most solid support and the only "royal husband" behind the empress. As a mortal, he made suggestions for the empress, managed internal affairs and external affairs, distinguished loyalties from traitors, solved puzzles, and finally assisted her to clear up the world and create eternal peace. He was also revered as a "Knowledge Sage" by the world because of his supreme merits. He perfectly interpreted the highest state of "soft rice" - you are responsible for ruling the world, and I am responsible for letting you dominate the world.
