"Warning! Warning!"
"Detected a signal from an Otherworld, identifying the signal source..."
At the same time, in a still-operating base somewhere in the Underworld, the shrill sound of an alarm echoed throughout the entire facility.
"Damn lackeys, is there another group of intruders?"
As the sole survivor of the base, a Burrowing Insect, with most of its body implanted with steel bones, cursed under its breath.
Because of severe injuries, this Burrowing Insect had to replace its spine with steel bones to barely survive in such an extremely harsh environment.
Even so, the rejection reaction between the biological organic matter and silicon-based structures caused the Burrowing Insect to endure pain akin to being slashed thousands of times every moment.
Moreover, such pain could not be subdued by anesthetics or similar drugs.
For the Burrowing Insect had to keep a clear mind for revenge against the Evil Gods destroying this world.
