Too far away from the Frozen Wastelands to feel the full extent of the terrifying clash that took place there by the time that the golden palm and blood sea crashed into each other, Xuan Hao only felt a few aftershocks of the battle due to his powerful divine sense as he was in the process of attempting to convince Gong Cheng to join the Star Shattering Sect.
Even then, the little he felt from the terrifying clash was still more than enough for him to get a general idea of the strength of the two people who had ended up clashing with each other. Determining them to at least be in the Land Creation Realm, likely stronger than a normal Land Creation Realm cultivator as well.
As for who it was that clashed? He had no idea, the only thing he knew for now was that it should have happened in the Frozen Wastelands and should have something to do with him.
