Three hundred years have passed since the Dajing Dynasty was in turmoil. The crape myrtle sword manual unearthed from the quicksands of the Western Regions contains the secret to subverting the court. Outside Yanmen Pass, Wudang leader Qingxu and Demon Cult leader Ye Cangming finally came to an end. Under the black cloth wrapping the two corpses, the traces of the sword manual became a mystery. Shadow Pavilion, Zhenwu Division, and Jianghu sects took action upon hearing the news, and bloody wind and sand swept beyond the Great Wall.
Three days later, in the misty rain in the south of the Yangtze River, Shen Yan, Qingxu's only disciple, held half a piece of jade in his arms. In the shadow of the lanterns on Pingjiang Road in Suzhou, he bumped into Su Wanqing, who was carrying a basket embroidering crape myrtle. Half of a silver lock is tied to the red rope around her ankle, and the jade hairpin in her hair is hidden with a Jue pattern - she may not know that the other half of the sword manual is hidden under the 300-year-old crape myrtle tree in the backyard of the Weaving Department; nor does she know that the light and shadow of the sword outside the Great Wall has been blown by the wind and sand to the bluestone lane in the south of the Yangtze River.
When the compass of the Shadow Pavilion points to Yujue, the secret agent of the Zhenwu Division knocks on the door. In this late spring, the fate of the young man and the embroiderer has already been involved in the fate of good and evil, the court, and the two generations. There is a long way to go, and there is no escape from disaster, and the sword manual that affects the world is just the prelude to a bigger storm.
