Apart from the Immovable Black Tortoise Formation, at this moment, there were also five Fifth Rank Supreme Grade Formations.
The Spirit Vein of Heavenly Phenomenon Island had gradually risen to a Fifth Rank Superior Grade Spirit Vein, and the surging Spiritual Energy caused the bodies of all the cultivators on the island to shudder involuntarily.
Clearly, in these past few days, several True Persons had infused the Spirit Vein with more energy; otherwise, Heavenly Phenomenon Island's Spirit Vein could not have sustained five grand formations!
Almost at the instant that the formations rose into the sky, Red Leaf True Person also shouted loudly:
"All cultivators of Heavenly Phenomenon Island, take your positions. This time, if we survive the defense of the island, we live, but if we lose and the Transmission Formation is destroyed, once the demonic race's reinforcements arrive, everyone will die!"
Red Leaf True Person's voice was extremely loud!
