The snow in the 23rd year of Yong'an is fishy. A suet-fat jade button with seven cracks dragged Princess Yongan Fusheng into the whirlpool of a series of murders, and also caused her to meet Hou Jingci of Zhennan amid suspicion. The jade soul devours blood, every crack corresponds to a human life, and every death awakens a forgotten memory. The two have their own concerns and are on guard at every step. From the turbulent palaces of the capital to the windy and snowy grasslands of northern Xinjiang, they work together to pursue the murderer, uncover their backgrounds, and finally avenge their mother and untie the grudges and promises of the previous generation. When the cracked jade is buried in the holy mountain, when hatred turns into the wind of the grassland, the two hearts, always on guard, stand side by side in desperate situations, stay together in suspicion, and finally find their fateful return in the sea of wolfsbane flowers in northern Xinjiang.
Purpose: Using jade as a contract and blood as a guide, it tells the story of two scarred people who, amidst the shackles of hatred and fate, redeem each other, break free from the curse, and finally find new life and peace of mind in a desperate situation.
