Angel chose to proceed on two fronts.
He consciously began controlling the spread of the Thorn Forest, directing it toward a location he had chosen where the space was relatively stable. That place would become the final gathering point for all the demon monsters.
Although the gathering point Angel had chosen already seemed quite spatially stable to him, who knew what it would look like after Laplace, red-eyed with slaughter, blasted it with dozens of Shed Scales?
So it was still better to reinforce it.
With that thought, Angel logged off once again.
After returning to the Reflection Space, Angel continued supplying Laplace with Shed Scales while pondering how to stabilize the space.
Angel had acquired a great deal of knowledge about space from Spotty Dog, including quite a few methods for stabilizing space. There were no fewer than ten methods he could currently choose from.
Yet after considering it for a moment, he did not make a choice from the spatial knowledge Spotty Dog had passed on to him.
Instead, he opened the Ultimate Luxury Nightmare Domain and took out a round-capped mushroom covered in red spots.
—Proliferation Mushroom.
This was one of the important strategic supplies Angel had brought back from Heart's Desire: an unusual mushroom cultivated by Minister of Agriculture Nuka, whose purpose was to stabilize the spatial fluctuations of a demi-plane.
A Nightmare Domain was, in fact, a different kind of demi-plane. Dream Wilderness, Broken Dream Wilderness, and the Dream Crystal Plain currently undergoing its cleansing battle were all variants of Nightmare Domains.
So theoretically, the Proliferation Mushroom was quite suited to the current situation.
The reason it was only "theoretically" was because Angel had never truly tested the Proliferation Mushroom's effects.
The reason was simple. Dream Wilderness had already developed for a long time back
