Yamata no Orochi is actually also considered a god, but strictly speaking, it can only be said to be a pseudo-god.
Yan Wuyue World, being a Fragmented World, is essentially just a tiny part of the main real world. The god positions self-nurtured in the Fragmented World cannot gain recognition from the main real world—there is overlap between the god positions of the Fragmented World and the main real world; the god position of the Fragmented World is inevitably obliterated by the god position of the main real world.
Therefore, being forced to leave Yan Wuyue World, and being knocked off the altar and returned to the main real world, Yamata no Orochi doesn't feel too heartbroken—unless it had resolved to hide in the Fragmented World all its life.
But even so, whether a pseudo-god or not, it has indeed initially stepped into this level.
More than anyone present, it understands what the aura emanating from this young man signifies—a Divine Lord, and one from the main real world.
