Michael guessed that these 'invisible' creatures were a form of bacteria that mutated into a magical creature.
Just like how this world had magical humans and monstrous demi-humans alike, it should have been obvious that there were also bacteria that evolved into a different species!
Fortunately, this specific type of bacteria lived upon the clouds and sustained themselves through polluted smoke. Not only that, they also produced an abundance of mana as a side-effect.
If the village had these types of clouds above, then they would bring water mana to the entire territory, no longer making it a desert!
He has always been hesitant to spread the use of petroleum fuel due to the harmful pollution that it produced. He had been using his own magic to counteract the effects of the pollution by himself, but with these bacteria clouds, he didn't have to do that anymore.
Michael immediately asked the Dwarven King how he obtained these bacteria clouds.
