Perhaps the array of this space is the core of its construction.
Thinking of this, Luo Chen glanced at the stone hall behind him.
His eyes gleamed with Spirit Light, carefully observing the flow of array patterns inside and outside, increasingly convinced of his speculation.
This seemingly ordinary stone hall combines the Gathering Spirits, Transforming Spirits, Dispersing Spirits, and Gathering Spirits four big formations, integrated yet without conflict.
At least with Luo Chen's current array attainment, he couldn't reach this level.
And this is merely the most basic array structure.
If this space had hundreds of similar stone halls, perhaps it could ensure the endless Spirit Qi inside, indistinguishable from the Outer World.
As Luo Chen contemplated this, the Sound Transmission Talisman on him reacted.
From Tian Xuan.
After listening, Luo Chen's face showed a surprised expression.
But in a flash, he buried that surprise deep, for Ding Yi and the others exited the hall.
