Chen Fei's expression subtly changed, imperceptible to others, but he knew—it was the Purification Array.
The entire Sacred City was covered with Purification Arrays, causing a noticeable difference in the spiritual energy compared to the outside world.
The Black Divine manipulated the rules, allowing monsters to appear anywhere in the Boundless Sea. If such creatures were to appear randomly within the Sacred City, it would be far from safe.
Therefore, the Purification Array was once again put into use.
By directly purifying the spiritual energy within the Sacred City, it prevented the possibility of monsters appearing here. Moreover, any monsters entering the city's range would be weakened by the Purification Array.
Compared to when they laid the Purification Array within the Black Divine Barrier, dealing with both the interference of the barrier and the precise placement of nodes was much simpler now.
