Henry turned his attention to the other demons that had entered the mortal world. The Kryptonian's gaze made them tremble.
The Goat-Headed Demon was the tallest, the most solidly formed, and perhaps the strongest among them. But in the Kryptonian's eyes, that did not mean the others were worthless.
Even a scrap was worth having. Henry decided to use the other demons as a comparison group to test his idea. By the time they realized they were in trouble, they wanted to turn and flee, or dispel their incarnations and return to their lairs. But as soon as they made up their minds to act, they found themselves back in the places they knew best. They had done nothing, and it was already too late to do anything.
Henry had pounded the remaining demonic incarnations into much the same thing.
It was hard to call the stuff "demonic essence." It clearly no longer had any demonic traits, or even any connection to the demons it had come from.
Despite the differences between the demons, what he had pounded out of them barely differed at all. Henry placed a square crystal no bigger than a speck of dust beside the rice-grain-sized crystal he had first made from the Goat-Headed Demon. He had pounded both to roughly the same point.
Sure enough, the rice-grain-sized crystal drew in the speck. The two became one.
This confirmed Henry's suspicion that the crystals shared a structure and attracted one another. This form was also stable after repeated fission reactions. Even pounding it with his fist produced no further change.
According to Wanda, it was not something that could be extracted from a human soul in the same way. Still, he could imagine how vanishingly small the amount would be. The whole matter brought to mind
