When the Demon Clan life forms ascend the thirty-three heavenly steps, they will offer a portion of their spiritual power, integrating it into the array, akin to an admission ticket.
Only after paying the admission ticket can they initiate the trials of the Spiritual Illusion Realm.
Furthermore, during the course of the trials, another portion of spiritual power will merge into the array.
While this may sound straightforward, it is in fact very difficult to accomplish, with many problems involved.
The array capable of accommodating spiritual power must filter the spiritual power layer by layer, and issues such as the balance between its use and collection abound.
Nonetheless, they eventually overcame these difficulties, achieving a balanced budget regarding the cultivation of the spirit in the thirty-three heavenly layers.
Overall, the collective strength of the Demon Clan has been on the rise, and their foundation is continuously growing stronger.
