In the streets and alleys of Jianghai City, a courier wearing work clothes and an old baseball cap is always seen riding an electric scooter - Han Wushuang, nicknamed "Softie Wushuang". When customers make things difficult for him, he only scratches his head and laughs. When moving goods, he can even smash cartons. No one knew that the rusty pendant around his waist was a nine-ring wind-cutting knife with seven broken blades; no one knew that this ferocious weapon that had once made the world fearful was now wrapped in cheap tape and following its owner to "gather dust" in the corner of the express station's warehouse.
Twenty years ago, the Jiuhuan Gate was bloodbathed by the Bone Corrosion Gate. A five-year-old child faked his death and escaped into the market, secretly editing the remaining volume of "Nine Changes in the Waves". Nowadays, the poisonous fog has reappeared in the night market, and the sinister smile under the bronze ghost's face is tearing apart the calm - the four guardians of the Bone Erosion Sect have come with poison and want to eradicate the roots; in the auction house of Yuntai Pavilion, the doctor in white holds the bloody scalpel and stares at the familiar scar in trance; while the silver needle rises and falls in the Shadow Tattoo Shop, the eyes under the silver crow's head mask are locked on the back of someone bending down to pick up a package.
