"Where are the people, have they hidden themselves?"
"Interesting, it seems they want to buy time."
"That's a wise move. Did you notice? The situation here is very different from the campaign against the Little Black Moustache Plane. The power suppression here is too obvious."
After entering the Extreme Beast Plane, Ivan and his group observed the surrounding conditions with keen interest, as well as the changes in their own situations.
They immediately sensed that the suppression here was unexpectedly ruthless, suppressing their power by thirty to forty percent, and increasing rapidly with the passage of time.
In fact, this is a commonality bestowed by the world's planes, granting them self-preservation abilities.
