[Evil] wants to completely infiltrate a world, but it's not that simple in reality.
Just as in the Old World where the Patient lives, there exists the "World Consciousness," also known as the Sick Focus.
There are even many organizations serving the World Consciousness, such as the Suffering Monastery on the world's surface or the Internal Affairs Management Team responsible for Path development and Patient ascension embedded within the world.
As long as the World Consciousness exists, the world will not be easily destroyed.
Even back when the Evil Sun fell, rules were sealed, and reproductive rights were completely stripped away, the Sick Focus was still capable of driving the world to wander across planes, seeking worlds with similar attributes and species for parasitism to ensure survival, guaranteeing the diversification and evolution ability of the illness.
