It tells the story of Shen Yanqiu, a young man who has just entered the world of martial arts. Before his master Mr. Liu died, he was entrusted to carry a mysterious red sandalwood box to Zhongnan Mountain and deliver it to an old friend named Yang. However, this wooden box attracted the covetous attention of Heifengzhai and other Jianghu forces, and Shen Yanqiu embarked on a journey full of crises.
While passing through the ruined temples in the Yandang Mountain area, Shen Yanqiu was chased by the masters of Black Wind Village. At the critical moment, he was rescued by Su Ningshuang, the daughter of "Hanjiang Sword" Su Muyun. Su Ningshuang went to Zhongnan Mountain this time to find medicinal materials that could heal her father's old injuries. The two had the same destination, so they decided to go together.
With the "Wandering Snake Step" and solid basic swordsmanship taught by his master, Shen Yanqiu continued to grow in the swords and shadows of the world. His tenacity, love and justice, and the chivalrous responsibility of a young man allowed him to gradually gain a foothold in the world. Su Ningshuang, on the other hand, protects her with the exquisite "Hanjiang Sword Technique". She is cold on the outside and hot on the inside. She has a strong sense of justice, and is burdened with her father's expectations and past legends. As she walks with Shen Yanqiu, she gradually opens up her heart.
Along the way, the two faced the continuous pursuit of Heifeng Village and the numerous crises brought about by the greater secret hidden behind the rosewood box. From the initial meeting by chance, they were wary of each other, to fighting side by side and trusting each other. In the battles and decisions, they jointly explored the truth about the wooden box, and also wrote their own legends in the wind and rain of the world. As the journey progresses, the secrets in the rosewood box are gradually revealed, and a storm concerning the world of Jianghu is quietly brewing, and the fate of Shen Yanqiu and Su Ningshuang
