As the last member of the Si family lineage in the Great Yong Dynasty who knew the ancient sacrificial dance, Si Yin's fate has been closely linked to this precarious dynasty since his birth. Her father and brother told her that her dance was the last hope, which could awaken the sleeping founding father of the country and protect all people. She practiced hard for twenty years, and on a night when the country was in danger, she performed a stunning dance on the 365-level white jade altar. Linggong woke up. But... It seems different from what is recorded in the history books? What about the "majesty, divine power, and golden light that protects the country" promised? Who is this guy who walks out of the cocoon of light, with lazy eyes, both good and evil, and the first thing he says is, "Little girl, you are the only sacrifice, who can fill the gap between your teeth?" Hey! What made her even more troubled was that the Crown Prince, who was known for his ruthless and iron-blooded nature, was actually guarding under the altar. In the long night, he was wearing black armor and his long sword was not unsheathed, but his aura was even more compelling than that of the awakened Duke Ling. Xiao Yan: "Si Yin, your duty is to wake him up, and my duty is to keep an eye on him - and on you. If he is a god, you will be a witch; if he is a demon, you will die with him... For the country." Si Yin: "..." Good guy, working two jobs for one salary is a waste of money. She has no innate magical power, only dance steps and etiquette that she has practiced hard for twenty years. She does not have a golden finger to predict the future. She only has the wisdom to deal with "gods" that she pieced together by extracting chapters and sentences from a vast sea of ancient books. When the ancient gods sneered at the rules of the world, and when the strange situation in the court became more and more turbulent due to "miracles", Si Yin discovered that the sacrificial dance was just the beginning.
