What happened when a device's output power seriously exceeded the limit?
Naturally, problems arose.
For example, all sorts of energy weapons would often suffer reduced durability because of this, or simply explode on the spot.
Applied to Lifeforms,
the situation could be likened to using something like the Sky Demon Disintegration Great Method.
In that case,
reduced durability could be equated to reduced Life Force.
As for exploding on the spot, there was no need to equate it to anything.
Just consider it dying right there and then.
Under such circumstances,
after unleashing the strongest attack they could temporarily muster,
both of them naturally appeared somewhat strained.
Had they not been Degenerators,
with incomparably clear knowledge and experience regarding the actual effects of attacks at this level,
and had they not made all kinds of preparations in advance,
perhaps
they might already have played themselves to death and made a hasty exit.
Just like when Orsaga fought the War Devil Counterpart.
They had nearly died beneath power they could not control.
In essence,
the current situation of these two fellows meant much the same thing.
When attempting to wield power beyond one's limits,
one would more or less have to pay a price and bear various risks.
However, comparatively speaking,
as Degenerators, the price they had to bear was relatively light.
At the very least,
the two currently fighting did not face any risks that directly concerned their own survival.
Moreover, they still retained control over their own attacks,
keeping the situation fairly manageable.
It even felt as though they could launch several more waves of attacks~
And in truth, that was not some meaningless illusion.
They really could unleash several more waves, or even many more waves, of the same attack.
As for the price required?
They merely needed
