"The Chaotic Evil Spirits"

The four archangels acted as the pillars of Armageddon Domain and with one of them dead, the pillars became unstable. 

But they still had more than one domain core scattered somewhere in the domain, hidden from people's sight. 

Both Gabriel and Ainsley's intention was to send spirits who could move fast and could not be fought by other creatures other than spirits themselves and related professions to find these cores. 

Destroying all the domain cores would definitely destroy the whole domain, even when the pillars were still there. 

However, eliminating all pillars would also make it easier to reveal the location of the domain cores, which would lead to the same fate— destruction!

Gabriel could easily summon 50 high-level spirits who could materialize, just like the Godfather, but the gap was like a whole ten levels.
