Wait a moment, let me sort this out.
Ybur felt dizzy as he reviewed what had happened.
Perhaps because he had turned into a demon, his meditation did not take him to the Dream Realm, but instead, in a confusing whirl, dragged him into the Abyss; and then, a Great Demon, the "Venom Sucker", appeared to check his body. Although he was like an intruder usurping a nest, for some unknown reason, the demon approved of him and even bestowed a blessing upon him... Ah, no, that's not right; the blessing was already there, it was just activated by the Venom Sucker.
But why?
Ybur thought hard and came up with a highly probable speculation: the blessing on him actually came from another unfortunate Mud-shaped Monster. But for demons, it might be about survival of the fittest, a rule where the strong reign supreme, so since he had seized the blessing, that was his merit, and considering that he now seemed to be a demon through and through, it made sense for him to inherit this blessing.
