That was the voice of the Nine Corpse Heavenly Demon Emperor. Lu Yuan seemed to have begun releasing the demon within his heart, gradually losing his sanity.
Xiao Yu saw the Demon Heart in Lu Yuan's chest slowly beating, and his brows furrowed slightly.
Qin Tian shouted, "Stop them! We must not allow the Nine Corpse Heavenly Demon Emperor to fully awaken!"
At Qin Tian's shout, the three Immortal Grade Heavenly Sovereigns behind him erupted with terrifying streams of Spiritual Energy and charged at the three Xuan Mo Emperors.
Boom!
With a thunderous explosion, the three Immortal Grade Heavenly Sovereigns instantly began battling the three Xuan Mo Emperors.
Qin Tian also looked toward the Heavenly Demon Emperor in the sky and said calmly, "Spirit Heaven Demon Emperor, have you come to the Great Thousand World because you wish to start an all-out war with us now?"
Xiao Yu looked at Qin Tian in surprise. He had not expected Qin Tian to recognize the Heavenly Demon Emperor before them.
Qin Tian had once seen this Heavenly Demon Emperor within the Outer Domain Evil Clan. Back when he had fought his way back alone from the Outer Domain Evil Clan, he had encountered him.
The clan leader of the Spirit Demon Clan, one of the Outer Domain Evil Clan's Thirty-Two Great Clans—the Spirit Heaven Demon Emperor!
Spirit Heaven Demon Emperor looked at Qin Tian, his black eyes narrowing slightly as he gazed at him coldly. "Qin Tian, do you think two Saint Grade Heavenly Sovereigns can stop me?"
Qin Tian looked at Spirit Heaven Demon Emperor. "We may not be able to kill you, nor can we stop you, but if you wish to cause trouble here, that will be absolutely impossible!"
Mohe Tian also looked at the Demon Emperor before him.
