The Sky Has Nine Dragons, The Responding Dragon Has Wings

In the book titled "Classic of Mountains and Seas—Classic of Regions Within the Seas: East", there was a god of thunder in Leize, Wu Xi, who had a dragon's body, a human head, and a bulging belly.

Although it was not stated explicitly, the Leize Dragon God was obviously a combination of human and dragon, and its meditation technique also came in two forms.

The feathered serpent spirit couldn't get close to the human form. It was much easier for it to move toward the dragon body, which was also elongated.
