In her previous life, she was the legitimate daughter of the Prince of Zhennan. She led troops in southern and northern wars and helped her father, the royal concubine, conquer the world. But he ended up marrying a barbarian and dying tragically during pregnancy. He is the master of the Qianji Sect. There are two rumors about him in the world: "He is so intelligent that he is almost like a demon" and "Keep away from strangers", but he is willing to be her adviser. "Ayu, if you want this world, I will work hard to give it to you." His vow from the previous life still rings in my ears. Living her life again, she vows to protect her loved ones and those who love her even to the death!
