Noah had only needed one hand to stop the charge of the snake. His body was in the upper tier now, which matched the strength of the snakes. Yet, he had fused with a dragon, so his physical strength was slightly above that of his opponent.
Of course, Noah would overwhelm it in that field if the snake was only a magical beast. Still, the words that it had spoken made everyone realize that they were facing hybrids.
Also, that hybrid had used the language of the other Mortal Lands, which didn't leave many doubts about their origin. The god of the Empire had probably put them inside the separate dimension after they lost the war.
There was another possibility though.
None of the cultivators there knew how the Immortal Lands worked. There was a high chance that hybrids lived in the higher plane since two of the two known Mortal Lands had managed to give birth to those species.
It was only reasonable that such creatures lived up there.
