With black hole bombs as weapons, the Collectors could neutralize all the varied, seemingly high-end trump cards of the Seventh Stratum.
This was something the Seventh Stratum had never anticipated. They had originally believed that, when dealing with the Amoeba, they only needed to be wary of the power it used to seal the spirit domain. They had never considered black hole bombs at all.
However, even if they had been wary of black hole bombs, it would have been useless. They simply could not understand what black hole bombs were. Their physical framework limited their cognition; one could not expect a group of people who practiced magic to understand science or physics.
What was more, black hole bombs revealed very little information. The Seventh Stratum only saw violent gamma rays erupt near or upon them, followed by a powerful pulling force that dragged them into an endless abyss within seconds. Soon afterward, they completely evaporated, leaving nothing behind.
With such scant observational data, even confirming a connection to black holes was a problem, let alone studying the mysteries of gravity or gaining an understanding of black holes. That was nothing but wishful thinking.
The battle entered a stalemate, a situation the Seventh Stratum least wanted to see.
As the attacking side, they needed to achieve their intended war objectives in order to claim victory. So what was their objective?
