At this moment, Spirit Ruins Realm, Ten Thousand Demon Cave.
This is the stronghold of the demons, and also the place where many Mahayana demons rest.
The central main city of Ten Thousand Demon Cave is built from the bones of billions of living beings.
The city walls are a billion feet high, inscribed with the Devour Immortal Rune and the Divine Annihilation Curse Seal, extinguishing Immortal Light upon contact.
In the city, there are a thousand demon halls, ten thousand demon palaces, each guarded by a top-tier demon.
This place harbors many Mahayana demons.
Deep within a towering palace, hundreds of Mahayana demons are gathered.
A dense demonic qi permeates around them, as if entwined with billions of resentful souls.
And at their head is the Time Poison Demon Ancestor, it commands billions of demons in the Spirit Ruins Realm.
Its form is withered like dead wood, its skin gray and wrinkled, like decayed wood that has lived for billions of years.
