Aster, who couldn't stop himself from looking at how those two finished their enemies with a single move, though those were probably their current strongest techniques, a Genesis Manifestation insta-killing a Law Integration being isn't something to joke about.
Especially because those two spirit beasts weren't small fries, like the snake and the falcon whose lineages had diluted too much for them to return to their origin before reaching the Heavenly Realms.
In a sense the gorilla and the centipede were on par with the people from the main branches of the Drage, because they develop a dragon characteristic in the Transcending realms, it's the proof that their lineage hasn't diluted to the point of being useless.
That being said, if their bloodline was on par with first generation dragonkin, they would have developed dragon characteristics while being in the Earthly realms… like Aster, Alice and Lilia, who even before all this had the dragon characteristic of the Drage.
