The clean-up on Scorching Sun Department's side is basically done; all the walking dead in the chemical plant domain have pretty much been dealt with.
They also have professionals here, running all sorts of tests to dig up the underlying logic of this chemical plant domain—once it's figured out, they'll have a way to destroy it.
According to their estimate, when the Soul Devouring Beast fell, it pierced the domain and used the Black Water to link this chemical plant domain, as its core, to a bunch of other domains, both known and undiscovered.
Now, all they need to do is destroy this chemical plant domain, and the Soul Devouring Beast will have only one fate left: falling into the void below. Given how it's been shrinking day by day, it won't last much longer before it snuffs itself out.
That's the best possible outcome.
