Most of the silver-blood demons did not pay much attention to the 'warm-up' before the real game. Even Yuchi Ba, the master of the Skeleton Island, was merely chitchatting with his bodyguards at first.
But the odd changes of the battle soon attracted his attention. After an exclamation of surprise, he started observing the two swirls of blood in the Lightning Prison with great interest.
One of the swirls was the battle formation made of fifteen bull-horned muscular demons.
The giants from the same tribe were moving in an orderly fashion under the command of their leader. They were not charging forward blindly, and occasionally, they would turn around and crush the demon beasts that had formed a group.
The demon beasts boasted some sort of wisdom, too. They knew the feeling of fear when they were under huge pressure. After being scattered and crushed by the bull-horned muscular demons, it would take a long time before they could regroup.
