Eighteen years ago, the massacre of the Shui clan shocked the world. After the night, all that was left was a little blood stain and the fragrance of magnolia that filled the house. People in the world thought that the Shui clan had disappeared from the world, but they didn't know that the new daughter Shui Su, who was born on the day of the incident, still survived. Eighteen years later, the selection of new disciples from Qingfeng Pavilion, the second largest sect in the Jianghu, once again stirred up a bloody storm in the Jianghu. The tenderness of the most powerful assassin in the Jianghu, Young Master Xi, and the cold and cold Shangguan Ke who appeared midway, carrying a blood feud, put Shui Su in a dilemma. At this time, the master of Qingfeng Pavilion ordered the three of them and the other two senior brothers to investigate another new case in the Jianghu... The secret that had been hidden for many years finally came to the surface.
