Beyond the forbidden ground, the Saints noticed this scene, and none of their expressions looked very good.
After all, many of the True Gods venturing through the forbidden ground were direct descendants of the Saints.
"What's going on with this forbidden ground? Why have so many Time Wraiths appeared?" one of the Saints asked.
Normally, only seven or eight Time Wraiths would appear on the first level of the Sea of Time's forbidden ground at most. Yet a whole swarm had suddenly emerged, far exceeding what was usual.
The blind clan's female patriarch wore a mask, making her expression impossible to see. She merely said lightly, "The difficulty of the Sea of Time should have increased this time."
The controller of a forbidden ground could influence its difficulty to a certain extent, but could not completely control the entire forbidden ground.
Ever since forbidden grounds were born in the God's Domain, the difficulty of all forbidden grounds had been continuously increasing, and they had even continued expanding.
For example, Soul Wilderness, a sixth-grade forbidden ground, was located in the Divine Soul Domain. At first, Soul Wilderness occupied only about one-tenth of the Divine Soul Domain's area. Yet with every Divine Era, Soul Wilderness expanded a little, devouring part of the Divine Soul Domain.
As Soul Wilderness grew larger and larger, its expansion accelerated as well. By now, Soul Wilderness had swallowed the entire Divine Soul Domain and begun expanding toward the surrounding Divine Dust Domain and Sealed Mountain Domain. The Divine Citizens living in those two domains could only keep migrating to avoid being caught up in Soul Wilderness.
Besides Soul Wilderness, Taki Whirlpool Forest and the other forbidden grounds, large and small, were all expanding slowly but surely. Even the Sea of Time was growing larger day by day.
