Upon seeing Cynthia's huge fair body with tree warts and flowers growing on it as though she was a tree, as well as hearing her shy, reluctant request, Klein couldn't help but shudder as his hair stood on end.
Such a scene exceeded a horror conceivable by human imagination. He had never encountered something like this even in his dreams.
If he were himself back when facing Megose in Tingen, Klein definitely would've been affected by such a scene. He would've temporarily lost his ability to react due to the horror and panic, but after experiencing so much, he was an experienced Beyonder in the true sense of the word. In the moment that Cynthia's words entered his ears, the glove on his left hand had already changed colors.
It had turned black, emitting a noble and sinister feeling. This meant that Klein had activated Creeping Hunger and had switched to Wormtongue Mithor's soul, giving him the powers of a Baron of Corruption!
