The play is adapted from the novel of the same name by Jiu Lu Fei Xiang. Twenty years ago, Tian Yao (played by Hou Minghao) was stripped of his tendons and bones by his beloved Guanghan Sect leader Su Ying, and sealed in all directions with the power of the five elements. By chance, Tian Yao escaped the seal ten years ago. He sensed that his dragon bones were sealed in the lake of a mountain village, so he hid in a small village, waiting for an opportunity to retrieve the dragon bones. Because Yan Hui (played by Zhou Ye) carries his heart-protecting scales and has dragon blood in his heart, he can help him break the seal. So Tian Yao began to use Yan Hui and let her help him find his body. Yan Hui originally intended to escape from Tian Yao, but not only did they fail to separate, their relationship became closer and closer. Tian Yao was moved by Yan Hui's loyalty to save him several times at the risk of his life, and Yan Hui also discovered that Tian Yao and himself could not be cut off in the events that were constantly involved. The origin of his heart-protecting scales, the relationship between Master Ling Xiao and Su Ying, and the confusing mysteries followed one after another...
