Holocaust Sect, in Eternal Chaotic World, was hated by everyone.
Especially by Fiery King, who once watched the merciless act of Holocaust Sect with his own eyes, and loathed them even more.
"It's a pity that it isn't Eternal Chaotic World, but Sky Sword Prison. Even if we find out about Blood Emperor's true identity, we can't do anything about him," Fiery King continued, "The experts in Sky Sword Prison are all prisoners. They have trouble even keeping themselves alive. Who would be bothered if Blood Emperor was one of the experts from Holocaust Sect. As for myself, even if I intend to take action against Blood Emperor, under the limitation of divine power, I can only suppress him and torture him. But it's impossible for me to kill him!"
Fiery King was publicly acknowledged as the number one expert in Sky Sword Prison.
Even if it was him, under the condition where his divine power was limited, he couldn't kill a King.
