This is the third part of the series of martial arts novels "A School of Xishan Eternal Show", "Xiyin Xixia Trace", which takes the mission of the Hermit Village Treasure Protector League to protect the secret road map as the main line, and interweaves the love between Shi Qing and Su Ningshuang. A hundred years ago, the Baobao Alliance hid in the mountains and forests to protect the secret road connecting the country and Beidi. A hundred years later, forces such as Black Wind Hall and Baihua House coveted the secret road map, breaking the peace of the village.
Young Shi Qing knew the mission under the guidance of his grandfather. When looking for allies, he first met Su Ningshuang, the daughter of the owner of Yanyu Tower, in a teahouse. They misunderstood and met each other and noticed each other. Along the way, the two shared many adversities: fighting back-to-back enemies in street battles, breaking down a temple to heal their wounds and revealing their feelings, and an old beggar revealing Shi Qing's feelings.
Liu Ping seizes the child and threatens her, Su Ningshuang saves the injured, and Shi Qing carries her through the peach forest and promises to protect her. The Marquis of Zhenbei tried to create a estrangement, but Shi Qing stood firmly in front of Su Ningshuang and used his swords to repel the enemy. On the day of the decisive battle, the two men joined forces to kill Zhenbei Hou, and their scars became the mark of their shared life and death.
After the war, Shi Qing became the new leader of the Treasure Protection Alliance, while Su Ningshuang stayed in the village to help. At the Peach Blossom Creek altar meeting, the two received blessings from everyone, and Grandma Wang gave them an ancestral jade pendant in recognition of their relationship.
Many years later, the Baobao Alliance was stabilized, Shi Qing and Su Ningshuang traveled far away with Linglu, and the sound of swords and laughter spread throughout Xishan. Their chivalrous reputation and love spread throughout the world, and became a legend that "a chivalrous person with a soft heart and a strong heart will live up to his family and country and his ministers".
