On Erlang God in the Romance of Gods.

Three of the nine dragons escaped from the mortal world to commit iniquity, and the jade emperor Otome Yao Ji asked him to come down to earth to hunt them down. On the way, I met Yang Tianyou, a scholar who went to Taoshan to seek Taoism, and got married. When the happy event reached the Heavenly Palace, the Jade Emperor was furious, and Guanyin Bodhisattva personally sent a decree urging Yao Ji to return to heaven. At this time, the couple not only gave birth to their son Yang Jian, Yao Ji was pregnant again, and the whole family was happy. Therefore, Yao Ji refused to return to heaven anyway. Guanyin Bodhisattva said helplessly that if the jade emperor was not offended by the decree, Yang Tianyou and his son would be ruined forever. Thinking of her husband and beloved son, Yao Ji had to return to heaven with tears in her eyes. In the face of parting, Yang Tianyou was unable to recover and cried unconscious on the side of the road. Fortunately, Liu, a girl from the village, woke him up and took Yang Jian home to raise him. Yao Ji went to heaven, but was still crushed by the angry jade emperor under Taoshan.

Ten years later, Yang Jian and his younger brother (stepmother Liu Suosheng) fought in the school auditorium and were killed. In order to protect Yao Ji's blood, Yang Tianyou tearfully made Yang Guang pay the price of his life, and told Yang Jian his life story and let him escape. On the way, Yang Jian was instructed by a fairy and went through hardships. Finally, he came to Yuquan Mountain, found the real jade tripod, and worshipped him to learn magic for his teacher. Wang Ding taught him a series of magical powers, and told his mother and sister that they were robbed to Kunlun Mountain by a demon dog and Hydreigon and asked them to rescue them.

On the Kunlun Mountain, the demon dog and dragon were killed by Yang Jian, and turned into roaring dogs and three-pointed double-edged knives for Yang Jian to use. Unexpectedly, at this time, Yao Ji's mother and daughter were taken to the heavenly palace by the giant spirit god. Yang Jian was so angry that he caught up with the fight. His filial piety touched the jade emperor, and he specially ordered Yao Ji's mother and daughter to be released and reunited.
