This Nine-Headed Nightmare Realm Demon God's Heart was originally a High-Tier Deity-level Advance Grade array treasure, the Nine-Headed Nightmare Realm Demon God Statue.
From the information on its surface, he could only tell that it was a top-notch True God-Tier Divine Artifacts that could summon a Nine-Headed Nightmare Demon God and make "Him" agree to a reasonable wish within the paramount law.
However, just like how the Spatiotemporal Region was the hidden ability of the Sword Of New Dimension Creation, as a top-notch array formation treasure, the Nine-Headed Nightmare Realm Demon God's Heart's ability to set up formations was also hidden.
As the upgraded version of the Nine-Headed Demon God statue, the Nine-Headed Nightmare Realm Demon God's Heart was no longer a High-Tier Deity's Nine-Headed Nightmare Realm Demon God's Heart. Instead, it was a top-notch formation of True Gods and Advance Grades—the Nine Worlds Demon God Dreamfall Formation!
