In the end, sensing the turmoil unfolding within the Dark Tower.
Mazhuling, as its Guardian God, ultimately chose not to step in and maintain order.
Because He knew full well.
Given the conflict between those two, even if He could stop them once, He was unlikely to stop them every time.
Besides...
He wasn't crazy.
Those two were both vile things anyway.
They wanted to fight?
Then let them fight!
Why should He stop them?
The harder they fought, the better!
Best if they both ended up battered beyond repair, trading one for one at the limit, then dying together!!
That would surely be wonderful!
They would be making an enormous contribution to the cause of peace!
Of course.
He also understood that, given the abilities of those two, a struggle on this level would find it difficult to make either side suffer any truly meaningful loss. Dead, then alive; alive, then dead—constantly doing sit-ups was the real norm.
Thus, after reinforcing their battlefield so that the various aftershocks would not scatter in all directions and affect other places.
Mazhuling slowly closed His eyes, adopting the attitude that what He could not see had never happened.
He continued drifting contentedly atop that infinitely vast ocean composed of glowing liquid.
Completely ignoring the two sides that were still desperately grappling and beating each other senseless.
However.
Some idle yet sufficiently powerful fellows were still watching the two sides PK with utter boredom.
Treating it as one of the rare amusements within their infinitely long Life Cycles.
For example, Pennywise's companions—the other Origins of Demons representing the chaotic side of this plane—were currently delighted by the situation.
"Well done!!"
"Bloody King!!"
"Beat that guy to a pulp for me!!!"
"Hit Him!!"
"Hit Him harder!!!"
"Pennywise, can you even do this??"
"Get him!!"
