The altar had been specially crafted by a method known only to the Otherworldly Demonic Tribe, and it required the Zhenqi of Slaughter to activate. More importantly, it concerned a secret of the soul oracles, so how could a master teacher possibly be able to activate it?
The Qingtian Emperor felt as if he was going insane.
Others might not have known how fearsome the altar was, but he did.
Once it was activated, it could draw even the Primordial Spirit of a Leaving Aperture realm expert into it easily!
Tzzzzzzzz!
Before the Qingtian Emperor could even give any further thought to the situation he was in, he suddenly felt the suction force growing stronger and stronger. Despite his resistance, his soul was slowly dragged by the suction force, seemingly about to be taken over to the other side at any moment.
