The Lightning Kui was the previous Lightning Dao Ancestor. It was just that it was born with a lightning physique and was able to move about freely in the Divine Lightning of the Nine Heavens. However, due to its affinity with the lightning techniques of the world, it was eventually swallowed by the Heavenly Dao and became a part of the world.
Appearance[]
It had body that looked like that of a bull, yet it had dragon horns growing out of its head. Not only was it massive in size, but there were also ancient runes growing on its round belly. There was only a single thick and muscular leg below it, making it look like a huge black hammer with a tail hanging down behind it. Its eyes looked like it was made of golden liquid.
