When Arno shouted those totally absurd words if spoken moments ago, those 13 individuals together with him around Lothur couldn't help but express their anger.
They were so close to getting the Soul Bone that Lothur would generate, but at the last moment, these 'hyenas' had shown themselves.
As intelligent people who knew that the formation of the Diamond-grade Soul Bone would generate discord among themselves, they could not allow such a thing to be formed!
If that happened, the unity between them would weaken, allowing these 'hyenas' to beat them and be the only ones to gain something from it all.
They refused to die for the sake of others, so if they couldn't have the chance to absorb Lothur's Soul Bone, they would rather such a thing didn't even form!
