When Su Fangzhou stepped into the Chui Gong Hall with a cup of tea, no one in the civil or military court looked at her. The maid who serves tea in front of the emperor is, to put it bluntly, the most inconspicuous shadow beside Emperor Zhao Zhen. What's even more ridiculous is that her face looks very much like the late Shen Hengwan - the legendary elven saint who died to save Zhao Zhen. A substitute, even she thinks so. But no one knew that the piece of ancestral rough jade on her wrist could store things, heal injuries, and even make her disappear and reappear in an instant. There is a saying in Song Dynasty: Mortal people are like ants, their spiritual rank determines their superiority and inferiority. She has no spiritual power and is born low, but any spiritual man in the court can make her kneel down and speak. Zhao Zhen asked her to replace Shen Hengwan at the ten-year Imperial Power Covenant Conference. He said she was a substitute, but in fact he asked her to be the abandoned child in the negotiations. Those cultivators laughed at her as a "spiritual waste", and Ling Buyi from Lingyunge, the largest sect in the world, even wanted to use her as a sacrificial flag. But they don't know that Su Fangzhou's jade pendant hides an entire mountain of monsters. When she threw out the third-level monster protector from her sleeve, when she assassinated invisibly under the eyes of the Holy Spirit, when she played the court's intrigues like a chessboard - the emperor realized that he couldn't afford to offend this substitute at all. But the secret of the jade pendant also attracted the attention of the elf clan elder Qingheng and the old monster Zhongli from the mountains. They told her: Mortals cannot practice because someone planted a bloodline curse thousands of years ago. And the key to lifting the curse is her piece of jade.
