The Strongest Realm?

Davis pursed his lips after he heard Lysan Auraflame's words.

Looks like he couldn't avoid confrontation with one of the most powerful and dangerous Upper Realms in this Galaxy, the Azure Dragon Upper Realm.

From Eiren's memories, including his teammates, he knew that every dragon-ruled Lower Realm worshiped the Azure Dragon Upper Realm as their leader, just like how phoenix-ruled Lower Realms adored the Seven-Colored Phoenix Upper Realm as their leader.

In the Minor Realms and Lower Realms, every dragon's aspiration was to head to the Azure Dragon Upper Realm and become a part of it. This aspiration shouldn't be taken lightly, as it was said the dragons of the Lower Realms made it their first goal upon learning about the cultivation universe, so much so that it is now almost imprinted in their inherited memories.

They literally dream of joining the Azure Dragon Upper Realm for no other reason than to bask in the glory of being a part of it.
