Liu Sanniang's life goal is simple: to guard her small embroidery workshop, save money, provide for her retirement, and become a happy single wealthy woman. However, things didn't go as planned. The new gang of thugs from the east of the city collected protection money one day, molested the little embroiderer the next, and almost had "I am a local snake" carved on their foreheads the day after tomorrow. Report to the official? Officials wear the same pair of trousers as them. Suck it up? It will only make them worse. Liu Sanniang took a deep breath, silently took out the small treasury she had saved for three years, gritted her teeth and stamped her feet - turned around and went to the most run-down "Iron Fist Martial Arts Gym" on the next street. From then on, Liu Sanniang lived a magical life of holding needles during the day and punching at night. During the day, she is the gentle and pleasant boss Liu who can embroider double-sided koi pictures. At night, she was a rookie apprentice who was whipped with a cane by her master and grinned. Mr. Xie Xiaohou, the most handsome man in the capital, has recently become obsessed with the embroidery of Yunjin Embroidery Shop. He runs there every two days, trying to catch up with the beautiful and skillful young proprietress. He thought she was a weak little white flower who needed him to protect her from the wind and rain. Until that day, he saw with his own eyes his weak little white flower who couldn't take care of himself. With a sharp look in his eyes, he threw the strong man who came to make trouble in front of him with a crisp over-the-shoulder throw. The strong man was foaming at the mouth, Liu Sanniang clapped her hands, looked back and smiled sweetly at him: "Oh, Mr. Xie, I'm sorry, my hand slipped." Mr. Xie Xiaohou: "..." Help, my delicate little white flower seems to be able to kill a cow with one punch!
