The most important thing was that the world's will of the Dongyuan Continent had been kept in the dark about the fact that most of the remaining high-level Cultivators were in the Evil Will World.
It was obviously impossible to do this by relying on the Malicious Thought World alone. It was possible to do this only if there were many macro worlds covering for the Malicious Thought World.
What this meant was self-evident!
The world where the Dongyuan Continent was located had reaped the harvest of the 3,000 macro worlds countless times. The region where the Dongyuan Continent was located was only one of them. Even so, it could be reaped once every 10,000 years. Each time, 3,000 reapers were sent out. One could imagine that the other regions would not be any worse.
