Nineteen-year-old Pan Yulian, a black belt in judo, accidentally fell to the ground while training with her boyfriend. When she woke up, it was Yanggu County in the late Northern Song Dynasty - she became Pan Jinlian. On the wedding night, the hijab was lifted, and in front of him was not Wu Da, but Wu Song, the tiger-fighting hero who was ordered to monitor the "disaster". The original owner Pan Jinlian was imprisoned in the backyard because she refused to marry Ximen. Wu Song was entrusted by the county magistrate to secretly guard her as a "brother-in-law". It took Pan Yulian half a day to understand the situation: this was the world of Water Margin, but she was not the poisonous woman, but another woman who was hunted by fate.
She didn't run away. On the first night, she exchanged a copy of "Creation Method" for Wu Song's promise: give her three months, and she will open a "Jiu Jitsu School" on Zishi Street - not to teach fighting, but to teach women how to avoid injury when falling and how to escape when their wrists are strangled. Wu Song went from alert to confused, from confused to watching. He watched her teach the cook how to be gentle, watched her use an account book to block Ximen Qing's acquisition, and watched her straighten her back when facing rumors. When the court purchaser unexpectedly discovered that her improved "Ten Forms of Defense" could be used in the military, and when the shadow of the Jin soldiers marching south spread over the Yellow River, this woman who just wanted to live her own life gradually became a thin but tough bone in troubled times.
But Wu Song is the hero who fights tigers and the sword of the law. The more respect he had for her, the less he could break the rules. And Ximen Qing, who promised not to disturb her, was spreading a net of silence for her on the northern trade route. On the night when the heavy snow closed the door, Wu Song tightened his grip on the waist knife, and Pan Yulian asked softly: "Second brother, in this world, if a woman doesn't become a martyr, or a disaster, can't she live an upright life?"
This is a story about prejudice, choice and self-accomplishment.
