Su Jinning, the leader of Jiangnan embroidery, suffered an injustice to her family ten years ago. Her father died tragically for "collaborating with the enemy and presenting pictures". She kept her name anonymous just to find out the real culprit. After hearing that Prince Jing's mansion was sorting out old cases, she sneaked into the mansion with her magical skill of "embroidering hundreds of birds with hair", but she bumped into Prince Jing Xiao Jue, who was locked up due to an eye disease and secretly investigated the culprits in the court.
He is the God of War who is visually impaired but can tell the position by listening to the wind. She is the embroiderer who hides the edge in her fingertips and can embroider secrets into her embroidery. From the mutual suspicion when they first met in the study, to being forced to cooperate in order to investigate the case - she sewed a "translucent eyepatch" for him to help him see, and he strongly protected her when she was ostracized; he sacrificed his life to protect her during a night attack on the workshop, and she risked her own life and went south to find medicine for his eye disease.
When the conspiracy of Lin Song, the Secretary of the Ministry of Finance, is gradually exposed, the two team up to reveal all the truth with a "Hundred Blessings" at the Queen's birthday banquet: the incriminating evidence hidden in the embroidery, the perjured map from ten years ago, and the poisonous arrow plot three years ago, all point to the same treasonous group!
In the end, the injustice was redressed, the embroiderer reopened the "Thousand Silk Pavilion", and the prince regained military power to guard the border. They changed from allies who tested each other to lifelong partners who "embroidered all over the country and protected the country". The whole process was a high-energy reversal, sweet and burning!
