Ever since Li Qian acquired that rhombus crystal, he frequently descended into the Black Extreme Palace through the deity statue within to observe the suppressed demon.
The Black Extreme Palace's grand array merely had a few gaps, weakening slightly, but still managed to maintain the suppression of the demon.
In the short term, it was almost impossible for the demon to break free from the array.
Moreover, his mind attached to the deity statue gave him an opportunity to survey the entire Black Extreme Palace grand array.
This grand array's scale... surpassed that of the Tianlan Immortal Mansion's array.
It's just that the focus was different.
The Tianlan Immortal Mansion's array had only fifteen foundation points.
While the Black Extreme Palace's array reached the level of sixteen foundation points. In other words, such a level of grand array is beyond the capability of even the Dutian Array Sect to arrange.
