"That isn't right. If the Great Evolution Civilization had methods like this, why didn't they use them when they fought us back then? And how do you know this is their handiwork? No, they must have told you something. There must be some unspeakable secret between you and them."
The Void Returner also stopped, because they knew as well that destroying the Restarters would be very difficult.
In fact, destroying even a Cosmic Civilization was very difficult, let alone a God-Level Civilization. A God-Level Civilization had already glimpsed the secrets of the Cosmic Infinite Safe; not only were its methods formidable, it could also run fast. Trapping one was actually the best approach. That was why, as soon as the battle began, the Void Returner had wanted to trap the Restarters on a one-way timeline.
Unfortunately, the Restarters were no pushovers either, and had escaped using their own methods.
So after that whole exchange, although the Void Returner had gained the upper hand, they also knew it would be hard to destroy the other side with the power of one civilization alone.
The two sides had clashed because of different philosophies. you came to stop me from doing something, I disagreed with your view, so I fought you, beat you until you cried, beat you until you ran, and made sure you could no longer keep interfering with what I was doing. That was enough.
Of course, when it truly involved restarting the entire universe or returning the entire universe to the void, the other side still had to be destroyed, persuaded, or locked away. Only then would no one interfere.
The Void Returner gave it a try and discovered that this kind of strike could not seal the other side. Added to the strangeness of the Fourth Phase Transition
