The play is adapted from Jiulu Feixiang's novel of the same name. Su Ying cramped and stripped her bones, and sealed it on Si with the power of the five elements. By coincidence, Tian Yao escaped from the seal ten years ago. He sensed that his keel was sealed in a lake in a mountain village, so he hid in the small village, waiting for an opportunity to retrieve the keel. Because Yanhui (played by Zhou Ye) has his heart-protecting Lin, he has dragon blood in his heart, which can help him break the seal. So Tian Yao began to use Yanhui to help him find his body. Yanhui originally wanted to escape from Tianyao, but not only did the two fail to separate, but their relationship became closer and closer. Tianyao was moved by Yanhui's loyalty to rescue him several times, and Yanhui also found Tianyao in the incidents that were constantly involved. Yao has a constant relationship with himself. The origin of the protective scales in my heart, the relationship between Master Ling Xiao and Su Ying, complicated and confusing mysteries come one after another..
