"Uh-huh."
At this moment, Zhou Sui was perceiving the entire Prohibition Array of the Phoenix Immortal Mansion.
Although he didn't have the Array Heart Gu with him, his Formation Cultivation Level had already reached the upper echelons of the Seventh Stage, which was an incredibly profound and inscrutable level.
Hence, he could barely sense the Prohibition Array of the Phoenix Immortal Mansion.
The whole Immortal Mansion seemed to be enveloped by an Immortal Array.
Unlike the Seventh-Order formations of the Spirit World, the pattern of this Immortal Array had completely merged into the void itself, almost like patterns of Principle integrated with this world, unfathomably deep.
No wonder even Mahayana Realm Cultivators could do nothing against the Phoenix Immortal Mansion.
The mere explosion of power from such an Immortal Rank Array could likely kill countless Mahayana Cultivators.
