Breakthrough
Ryu's gaze turned cold. He was the one receiving the most direct benefits from his own breakthrough, of course, so he didn't need to focus very much on it. After all, it was his insights that had triggered the breakthrough, not the other way around. So, he had already achieved the level of focus he had needed already. All he had to do now was to allow the Heavens to reward him properly.
Due to this, he was the first to realize what was happening because his Void Spiritual Sense was blanketing the area. With its prowess, Sky Gods of this level couldn't hide their intentions toward him, but it was already much too late for him to do anything.
The Frost Clan unfortunately hadn't left behind any world shattering treasures or protective treasures. Well, at least none that were useful on a Sky God level. The best of them could just barely block a few blows from a World Sea Realm expert of the Sixth Heaven's caliber.
