[Lucy's POV: ]
The power that the emperor had obtained through that ambiguous ritual was in fact the power of corruption. However, unlike the normal power of corruption that is born in the deepest consciousness of the victims, this power of corruption was an external force.
It was obtained from outside and did not belong to him, ultimately it was something like a parasite that belonged to somewhere else and he gave it a place in his body.
'However, this parasite was different from what he had thought it to be.'
Surely it was a seed that gave him greater power than what he possessed at the moment. It was certainly something that he could contain within himself with his divine powers as well.
However, the truest nature of this corrupt power was dark in nature.
By nature, this power corroded everything that it interacted with, including the divine powers and the entire existence of a being that comes in contact with them.
