The episode revolves around the Kunyin Pill, a powerful medicine that increases one's skills but has a deadly side effect if not taken continuously. The Xuanyuan Sect is being controlled by the Sky Hall, who are using the Kunyin Pill to manipulate the sect's members.
Meanwhile, Ling Long and Min Yan encounter a demon spirit in the forest, who is using the Jialuo blood vine to capture and feed on humans. The vine is being used to make blood fruits, which can make a cultivator powerful.
Si Feng and Chu Xuan Ji are searching for Ling Long and Min Yan, and they eventually discover the truth about the Jialuo blood vine and the demon spirit. They also learn that the demon spirit is being controlled by a charm stone, which is being used by Elder Ling Shi of the Xuanyuan Sect.
