In fact, the claim of the Scarlet Count was completely correct and not exaggerated at all, "Demon Technology" was exceedingly rare, found only among a few Old Kings.
The Swollen Doctor following at his side was also quite self-aware.
It was just like seeing a finished product of "Demon Technology" here, he had never thought that he himself could harness and control such technology.
However, the Swollen Doctor had always been doubtful.
The Old King Gear he acquired from the ruins of Stuart Manor, which also belonged to a type of biological machinery, could it also be from "Demon Technology"?
However, the relationships among Old Kings, secrets, and the various rules were far too numerous.
Even for the doctor who had reached the Mature Body, it was very difficult to pry clearly and to understand the nature of the gears in his brain, he must talk face to face with the King of Ghoul [M.O.].
Yet, nobody could have thought of it.
