Why was the dragon family so powerful, and could even be singled out as a department?
Because dragon attributes were very special. One attribute contained two or more attributes.
For example, in the dragon element of the Eastern Divine Dragon, it basically contained the nature of wind and water elements. Some of them also had the nature of lightning. As for the dragon element of the Western Dragon, it basically contained the nature of lightning and fire elements. At the same time, there was a chance that it had the nature of wind.
This was also one of the reasons why the dragons were powerful. A dragon type could be used as a multi-element. Moreover, due to their racial talent, they could perfectly control this type.
Therefore, if it had the ability to completely control these powers, it would definitely be able to play more tricks than with just a single attribute.
