"Damn it, have their energy reserves not run out yet?"
In the blink of an eye, several months had passed. Insect Emperor Behemoth looked back and discovered that the artillery fire from the Void Fortresses had never ceased.
Just how well-prepared were these natives?
Could it be that they had drained the energy of this entire universe just to deal with them?
If that were truly the case, these natives were insane enough.
This was a case of killing eight hundred enemies at the cost of one thousand of one's own; even if they were driven away, this universe would be ruined.
Insect Emperor Behemoth had guessed wrong, though not entirely.
The energy for the Void Fortresses did indeed use the Endless Star Sea as a reserve pool, but Medivh and the others were not deranged enough to sacrifice their home for the sake of destruction.
This was normal energy consumption; at the current rate, even if the Outer Insect Swarm were wiped out, the Endless Star Sea would only have lost a fraction of its vitality and would recover after some time.
It could only be said that the efficiency of Luna's Psionic Net in transmitting and utilizing energy was simply too high.
When it came to consumption, Medivh and Luna had never feared anyone since they formed their partnership.
The Outer Insect Swarm claimed to devour everything to grow and breed, but they could find no advantage here.
When a Bone Knight fell in battle, their flesh and blood sublimated, and they reincarnated as a Bone Spirit to continue fighting the Insect Beasts.
When a Bone Spirit fell, its soul would be sent by the Styx Ferryman to the Underworld for rebirth, leaving behind only useless dust.
It was impossible for the Insect Beasts to devour their enemies
