Vale had an impressive improvement over the past year.
It was all thanks to his Master's misunderstanding about his love for the cold corpses. Of course, because of this benefit, he can't say otherwise, or else, he would lose his chance to extract corpses.
His Master Heinz would even go as far as collecting corpses from the outside just to give them to him. On his fourteenth birthday, he also received a dozen of corpses that were previously Arcane Arts Practitioners! Those twelve corpses were even beautiful women when they were still alive!
Up until now, he would still shudder every time he recalls his Master's birthday present. When he returned to his room, he saw the 12 naked female corpses lying on his tiny room's floor and bed.
He can't even complain to his master and can only accept it with a smile.
In any case, Vale still feels happy every time he sees his current attributes.
