The Demonic Deduction technique advanced with Noah's mind, but it also fed on his bloodlust. The latter was nothing more than a violent feeling that carried pure destructive meanings, so the death dragon's aura worked even better when it reached the scarlet lines.
The expansion of the Demonic Deduction technique hurt as scarlet lines dug the mental sphere to stretch and create a tighter array that filled the insides of Noah's mind with a red radiance that shone above and under the mental sea.
Noah felt as if his existence was on fire. He felt an aspect of his law intensifying while the dragon's energy continued to fuse with his scarlet lines. His violent thoughts started to touch nefarious topics that he had never even considered. Their destructiveness wasn't pure anymore. It gained a meaning that actively tried to spread death through the world.
