King's Beloved Enemy Princess

He was the shrewdest, wisest, most cold-blooded and ruthless young Son of Heaven in the dynasty. She was the most mysterious and legendary Grand Princess of the Southern Tang Dynasty. She calmed the internal strife and supported the young Emperor. 
He wanted to unify the world, and she wanted to protect her home and her country. He had searched the entire world to kill her, but she had risen up every step of the way in his harem, and she was favored by six palaces. One day, when her secret identity was revealed, would he love her as he had ever loved her? At that time, he disregarded the courtesies of the court, and the officials of the court all disagreed, dispersing the six palaces for her, giving her a moment of favor. He said, "Susu, you are not only my queen, you are also a woman who wants to see the world with me." At this moment, above the jade steps, he was sitting on the Dragon Throne.
