Michael suspected that these 'invisible' creatures were a form of bacteria that might have mutated into a magical creature.
After all, just like how this world had magical humans and monstrous demi-humans, it was obvious that there were also bacteria that would have evolved into a different magical species!
Fortunately, this specific strain of bacteria thrived in the clouds and sustained itself by consuming the polluted smoke. Not only that, but they also produced an abundance of mana as a byproduct.
If he could bring these special clouds above his village, they would bring water mana to the entire territory, transforming the harsh desert into a fertile territory.
Until now, Michael had always been hesitant to spread the use of petroleum fuel due to the harmful pollution it produced. He had been using his own magic to counteract the harmful effects of the pollution. But with these bacteria clouds, he wouldn't have to do that anymore.
