"This is confidential." Dayton faintly smiled: "However, as the one with the qualifications of a hunter I can disclose to you a thing or two. The raw materials for the "God's blessing" are taken from these crystals for enhancement of the physical strength. The human who is infected would have his/her sould crystallized because of the resentment. As a result a degenerate undead or monster is made up."
Dudian was confused a bit.
He remembered that after he was branded with the magic marks while he was in coma he was able to absord the soul crystal and it didn't hurt.
Was the magic mark the real reason?
"Even hunters can not use them directly?" Asked Dudian.
Dayton shook his head, "can not."
