The Dark Spirit Clan and the alien tribes of the Fifth Realm of Purgatory actually aren't much different.
They too have a power system based on Bloodline advancement, and among them, there are strong individuals who can transform into God Spirits.
Within the Dark Prison, they also have Altars of Praying to God that work in a similar way, facilitating communication with the God Spirits related to them.
Pang Jian had long been familiar with the function of the Altar of Praying to God.
The true purpose of the altar was to serve as a location coordinate that could be sensed by Alien God Spirits from Outer Space, inviting the descent of a God Spirit's consciousness through certain special objects and certain special people.
As for whether the descending Divine Consciousness would possess someone or attach itself to a special artifact depended on the preferences of the Alien God Spirits.
