Just as their group moved, another Wonder Beast came down. It was Kafan's opponent, who couldn't stop Kafan's power. Kafan might not have the same level of Chaos Cultivation as the twins, but he was definitely above the other Semi-Celesitals in this regard. Besides... he also had his own self-created energy: The Gray-Blue fused Soul Power, Divine Origin Energy, and Death Energy. With that, even without having to change the laws, he got rid of his Wonder Beast.
Their group then looked at Sansara, who was still fighting his own Wonder Beast. Not only that, during their battle, one thing became clear. All the Wonder Beasts were ignoring them, trying to get to Sansara at all costs. That definitely made their battle a lot easier.
Sansara, obviously, noticed that the twins' group battles were over, leaving only himself to deal with his own Wonder Beast. "What are you all looking at? Help me finish this thing!"
