Qian Chu didn't show any reactions to Grand Elder Cen's words, and he focused on the Demon Emperor that was ready to release its next attack.
"Demon Sealing Formation!"
Grand Elder Suo suddenly created a massive formation around the arena just in time, halting the Demon Emperor's attack for a brief moment.
During this moment, Grand Elder Cen retrieved his treasure that radiated with demon sealing aura.
"Bastard! How dare you kill my people!" He shouted in anger as he unleashed a devastating attack that sliced the ball of blood in half.
The next second, the Demon Emperor regenerated until it returned to its original state, and it lifted its head to look at Grand Elder Cen and the others.
"I don't know what went through your heads that made you believe it would be a good idea to set me free, but I must thank you for releasing me." The Demon Emperor said to them with a calm smile on its face.
