201 - Macabre Scenery
Noah's uncle's residence was a very luxurious house, to the point that he and his family practically lived in a secluded village. Not only was it isolated, but it was also heavily protected by armed and Blessed Rank E humans who patrolled the site looking for intruders or any other unusual thing.
But since it was an isolated village it meant that there was only one way to get to the house, and it was exactly on that path that Noah would ambush him.
What he wanted at that moment was not just to kill his uncle but to make his uncle feel the same terror and suffer at least a similar amount to what his mother had felt. He wanted that man at times to cling to life but at other times wish for the clemency of death.
