Ten years ago, the family of Shen Muyun, deputy leader of the Xuantie Alliance, suffered a tragedy. When fire engulfed the Dongting Courtyard, his young son Shen Yanqiu (formerly known as Chutian) was rescued by a servant. Only half of a bronze token with the word "Xuan" engraved on it was left in his arms. For ten years, he practiced the family tradition "Liu Feng Hui Xue Sword" (can be changed to "Han Yan Sword Technique") and traveled around the world under a pseudonym, vowing to find out the truth behind the tragic death of his parents.
While passing by a solitary grave in Xiangdi to worship, Shen Yanqiu was chased by the Nether Sect. Fortunately, he was saved by Lu Jinghong (formerly known as Zhao Tingshan), the son of his former servant and now a disciple of the Hengshan Sect. When the two reunited, they met the innocent girl Su Qingxu (formerly known as Bai Ling'er) who was collecting medicine. The three of them were involved in a new round of pursuit. At the critical moment, they hid in the "Baicaotang" medicine hut and met Su Wanqing (formerly known as Ye Erniang), who was skilled in medicine and well-informed.
Su Wanqing's grandfather was once a doctor of the Black Iron Alliance. She revealed a shocking secret: the destruction of the Shen family was not caused by the Nether Cult alone, but famous sects such as Wudang and Kunlun were behind it. The core cause was the "Secret Scroll of Mountains and Rivers" guarded by the Black Iron Alliance - a fragment of a book recording the treasures and magic weapons of the former dynasty's Hidden Soldier Valley. Four fragments of the scroll (the original setting is three, can be optimized to four to enhance suspense) are scattered in the world, attracting the covetousness of various forces.
As the investigation deepens, Shen Yanqiu and the resourceful Su Wanqing gradually fall in love, but they dare not get close because of hatred; Lu Jinghong silently protects Su Qingxu, and his secret love is deep in his heart; while the hypocritical mask of Wudang Taoist Priest Ziyang (formerly known as Taoist Priest Qingxuan) and the Nether Sect Mo Huaishan (formerly known as Liu Chengfeng) are pressing closer
