During the reign of Emperor Qianlong, the young Hu Fei entered the dangerous world of Jianghu to avenge his father. He grew from a reckless boy with courage but no strategy to a great hero who cared about the people and served the country and the people. On the way to revenge, Hu Fei offended the bully Feng Tiannan because of his injustice, and had a tragic love affair with Feng Tiannan's daughter, the Tianshan School heroine Yuan Ziyi. When Hu Fei found Miao Renfeng, Miao Renfeng had been framed by the insidious Tian Guinong and was blind. Hu Fei was unwilling to take advantage of others' danger, so he took the risk and came to Yaowang Valley to seek an antidote. In Yaowang Valley, he met Cheng Lingsu, a disciple of the poisonous hand medicine king, and a tragic story happened between the two. As clues continued to emerge, it turned out that there was someone else who killed his father. Hu Fei gradually developed admiration for Miao Renfeng. Hu Fei finally got rid of the real murderer Tian Guinong, avenged his great hatred, and finally worked together with Yuan Ziyi to smash Fu Kang'an's conspiracy.
