"Qingfeng Washes the Moon" tells the story of Chu Jiangliu, a young man by the riverside who grew up in the world. In late autumn, Chu Jiangliu sailed the broken ship "Duckweed" to Yangzhou to make a living. At Duanyundu, he encountered Xiao Qianjue, the protector of the Black Wind Sect, and was accidentally involved in a dispute between the rivers and lakes. He relied on his self-invented swimming fish footwork to escape pursuit, and met Su Qingyuan, who was carrying the Ancient Scroll of Cleansing the Moon and was being hunted by the Black Wind Sect.
The two fled all the way with the ancient scrolls, and experienced dangerous situations such as fighting against the black and white evil spirits in Wangshui Town, and encountering martial arts guidance from the reclusive master Lin Mo in the misty forest. Later, they arrived at Yanyu Tower with the help of Jiangnan cavalry. Chu Jiangliu learned the Yanyu sword technique from Liu Changfeng as his master. Su Qingyuan also gradually exposed the conspiracy of Shangguan Xie, the leader of the Black Wind Sect, to practice the Heart-Eating Demonic Skill.
After the establishment of the Righteous Alliance, everyone pointed their swords at the Black Wind Sect's main altar. Chu Jiangliu combined the Yanyu sword technique and the Xiyue sword technique to finally kill Shangguan Xie. After that, Chu Jiangliu and Su Qingyuan performed chivalrous and righteous deeds in the name of "The Heroes of Misty Rain". Although they went into seclusion for a time, they came out again due to the rise of the Sky Eagle Sect and the kidnapping of their sons, and joined forces with their martial arts colleagues to eradicate the Sky Eagle Sect. In the follow-up, a new struggle in the world will start around the Chaos Stone, Lingxi Sword, etc. Chu Jiangliu always adheres to chivalry and protects the people around him and the peace of the world.
