Chapter 815: Chapter 366: The Power of the Immortal Artifact, Shattering the Void, Exterminating Divinity Transformation Demons_4

"Make your move, set up the formation."

The Dark Demon Jiao bellowed, issuing orders to numerous Divinity Transformation Demons.

Boom boom boom~~

In an instant, each Divinity Transformation Demon took out a black flag from themselves, each engraved with the images of Ancient Demons and exuding a terrifying demonic aura.

A total of one thousand and twenty-four Divinity Transformation Demons made their move this time.

The many flags combined instantly to form an unparalleled great formation.

Ancient Demon Extermination Formation!

It could be said that this set of flags was the crystallization of wisdom from many Divinity Transformation Demons of the Ancient Demon Realm over a million years and also one of the terrifying methods mastered by the Demon Clan.

The power of this great formation had almost reached the Sixth stage.

Once the setup was successful, it could summon the phantom of an Ancient Demon and unleash apocalyptic power.
