Dragons

"'In the past, Europeans refer to dragons as calamities, mainly because the dragons were just too powerful, so powerful that every effort a tribe or a country put in was destroyed within a night. Since then, humans were hoping to have power, a power that would allow them to take on the dragons…” - Su Lu"One of the most powerful and long living species in the series. Dragons had long lifespans, but their reproductive ability was extremely weak, especially the true dragons with noble lineages. So most of the dragons that most people encounter nowadays are merely pseudo-dragons or crossbreeds. The number of true dragons in the world had a tendency to remain the same. It neither increased nor decreased.

Dragons however were very lusty. When they could not find their own kind to fulfill their desires, they would look for species similar to them. The most common species that the dragons ended up mating with were lizards. As a result, there were many dragons with mixed lineages in this world. If one was strictly referring to their lineages, those with only a slight relation to dragons were normally referred to as crossbreed dragons.

True Dragon
It was stated by Su Lu that the main power of a Dragon is it's breath, it was a true dragon’s deadliest weapon. It left nothing alive as it surged across the land. An emperor level Dragon's breath can destroy any forbidden curse so even a Forbidden Mage might die before it, and thus was why a true dragon was deemed an inviolable existence. The dragon breath also possessed such a strong absorbing force that Super Wind Mages could be helpless if caught in it. The roar alone of a true Dragon was enough to torture peak advanced mages and render them unconscious.

A dragon had control over different magic, especially a Black Dragon. There were different kinds of dragon breaths, each bringing a different form of destruction, among them, Dragon Flame was like a falling sun. It would turn the surface into pits of flames and lava that would take centuries to recover!

Outside of that a Dragon's scales are sturdy enough to resist damage from Super Level Magic. This was proven during the attempt to capture the Black Dragon Emperor when even scores of Super Mages were barely able to survive the battle even with it's flame breath sealed.

Ranks & Strength

 * True/Real Dragon - Typically high ruler level at the very least to high emperor level.
 * Lesser Dragon - were very strong, ranked at the top among demon creatures. The number of Lesser Dragons was slightly higher than the true dragons. Almost every adult Lesser Dragon would be a Ruler-level creature. Not only did they possess a dragon’s scales and draconic might, they could even unleash dragon breath that was very close to the level of a True Dragon
 * Pseudo-Dragon - Referred to as dragons with purer lineages, They were a lot stronger. The weakest among them was at least a Commander-level creature, and the strong ones could even reach the Ruler-level. The pseudo-dragons had insane vitality and strength, as their blood had truly inherited the power of the dragons!
 * Crossbreed Dragon - Their strength ranged from the Warrior-level to the Commander-level, and they usually had very sturdy flesh.
