The Yin God sent his son Gao Yan. When he was born, there was a Yin Division commander guarding the gate, but his grandfather told him that he would not live to be eighteen. In order to avoid death, he became a beggar, burdened with five marriage contracts and purple secret skills, and was accidentally bound to the nine-tailed fox demon Tushan Wushang. On his eighteenth birthday, the engaged couple either abandons the contract or sticks to it, and the Yin Department asks for his life one after another. He can only rely on secret techniques and the power of the fox to survive in the conspiracy between Yin and Yang and explore the truth about his fate.
