Three horned dragon
Yao Wang was the first to see it after feeling the princess of something demonic, nevertheless Lu Wu also discussed it's peak and both her and her clansmen were immediately informed about it.

There were just three kilometers left to the alter when, all of a sudden, a huge red-white monster emerged from the top of a bluish mountain several kilometers away.

There was a bolt of lightning that lasted for seventeen seconds before disappearing. This was what made them view the hovering monster and get the most details of its construction.
