A hero saves a beauty in Jiangnan Embroidery Shop, and the missing sword spike reveals an obsession that spans three generations. Su Lingruo, the embroiderer who hides the blood of the spirit fox, uses a needle as a pen to outline her fateful love. From the heartbeat of reciting poems under the moonlight to the undercurrent of the chess game in the deep palace; from the determination to cut out the heart and detoxify, to the tragic feeling of losing one's soul, they traveled through time and space during the changes in the blood moon and regained their memories on the banks of the Wangchuan River.
When the evil spirit appears in the world, he destroys his own soul and seals the darkness; when the people are in danger, she devotes all her cultivation to protect the world. After ten reincarnations, crossing the boundary between Buddha and demon, thousands of miles of mountains and rivers are not as good as the cinnabar between her brows, and thousands of years of loneliness are just in exchange for playing chess with her under the moon. Life is like a dream, and love is drawn. This love that spans time and space will eventually write an oath that will never fade when the stars return.
