Su's Yaolu in Jiangnan was framed by the Yantian League and destroyed because of the "Secret Records of Qingnang". His legitimate daughter Su Wanqing hid in the Wuyin Valley of Qingchuan, using golden needle medical skills to help the world and secretly investigate unjust cases. Shen Qingci, the young master of Hanyue Sword Sect in the hidden world, went down to investigate the crime of colluding with the Demon Cult by the Yan Tianmeng. He was poisoned and fell into Qingchuan. He was rescued by Su Wanqing using forbidden magic. While recovering from their injuries, the two witnessed each other's benevolence and chivalry, and formed an alliance due to their common enemy. They went to Luoyang together to search for the fragments of the secret record and search for incriminating evidence. On the way, they uncovered the Yantian Alliance's conspiracy to refine banned drugs, uncovered the mastermind behind King Zhao's rebellion, and discovered the connection between the mothers of both parties and the "Secret Records of the Green Bag". After experiencing shocks in life and siege by Jianghu, the two gathered their forces to form the "Qingchuan Alliance", used medicine to break the situation, used swords to protect the road, and finally put down the rebellion in a decisive battle in Beijing. After the war, the two refused the generous salary from high-ranking officials and retired to Qingchuan to rebuild the medicine house. They healed all living beings and spread the right path with the sword, interpreting the legend of "healing all living beings and protecting the beloved with the sword".
