Five years ago, Su He's entire family was wiped out by his uncle. Five years later, at the International Embroidery Exhibition, she embroidered "Splendid Rivers and Mountains" stitch by stitch, but at the moment she turned over, bloody memories reappeared with the threads squirming - the night when her whole family died tragically, and her uncle's sinister face. The young master of the Wang family who returned from studying abroad handed over the cooperation contract. When the lost pages of the "Secret Book of Tiangong" were revealed, she realized that what the fire could not burn was not only the blood feud, but also a secret embroidery technique that could subvert the era... From an orphan to a master, she used the needle as the blade and the thread as the pattern to embroider a revenge feast that shocked Shanghai.
Su Jinse and Wang Jingyun started by investigating a smuggling case and gradually became involved in the "Shadow Warrior" plan and the old affairs of the "Shou Zhuo Society". With the help of the warlord Yu Cheng, who was both an enemy and a friend, the three formed a dangerous alliance. In the fog of Shanghai, they dealt with Japanese invaders, traitors and various forces. They finally locked on the target - the "Black Pill", which was about to transport the national treasure and compatriots, and planned a thrilling ship robbery. The story interweaves personal revenge, protection of national treasures and love in troubled times. Between embroidery needles and gunfire, it composes a legend of the Republic of China about faith, choice and protection.
