Pollution was drawn to living creatures. Though the reason was unknown, that made it very convenient to exploit.
Theus's current plan was to use living creatures to lure the pollution at the bottom of the abyss to the pipeline, collect it there, and then use a steam engine to transport it to the island.
This would provide a constant supply of physical pollution. Although Theus could bring down pollution through Cognitive Interference, it was not stable enough and required a vast amount of land—the pollution brought down by Cognitive Interference would randomly appear across a very large area.
What industry valued most was a stable supply and output. Building a tunnel leading to the Abyssal Trench would be troublesome, but if it could provide an endless supply of fuel, then it would be worth it.
Besides, he had other ideas for this passageway. The current project was merely a test. If the banshees could truly complete it, he might be able to make even more... modifications to Castel.
Buildings on Blue Star were affected by many factors, such as foundations, groundwater seepage, and all kinds of settlement-related problems.
Although the Banshees could not entirely avoid such issues, they could handle them with ease. Turn Stone to Mud made excavation within rock layers extremely simple. If a collapse occurred somewhere, digging it out again and reinforcing the supports would not be difficult either.
And it was not merely convenient for construction. Even if an accident occurred, the banshees would suffer virtually no casualties.
Flesh Magic could be activated instantly. Whether it was pollution or magma, it could hold out for a while. If it was merely something like water pressure, they could keep it active indefinitely.
And if they were injured, the Symbiotic Pact would quickly repair and heal them. Buried
