The Four Divine Beasts of Heaven and Earth were born at the beginning of the universe, as one of the earliest creatures, even predating the Five Great Saints.
After countless years of reproduction, the Four Divine Beasts have large numbers of descendants and established their own factions. Among them, the domain established by the Old Azure Dragon is the Dragon Domain. Although initially not as powerful as the forces of the Five Great Saints, it did not suffer significant losses in the great battle from a million years ago, preserving its strength, and is now the top-tier power in the Bright Realm.
When heaven and earth gave birth to all things, the stronger a creature, the fewer in number they would be, especially for beings like the Four Divine Beasts, unique in all existence.
