Perhaps it was because of Shava's status, or perhaps because Boiling Gentleman had always carried out his modifications alone and longed to share his achievements with others.
So along the way, before Angel even had to ask, Boiling Gentleman proactively explained the general principles behind these Demonic Beast modifications.
The core of the Demonic Beast modifications Boiling Gentleman had mastered lay in the power furnace.
In the black-and-white maids, the power furnace manifested as their hearts; in this bone leopard, it was the glowing metal sphere within the framework of its abdominal bones.
At first, the power furnace seemed somewhat similar to a power source in Angel's eyes.
A power source was, in essence, the source of power that sustained extraordinary effects.
For instance, when an alchemical item suddenly lost its intended effect, there were generally two possible causes: either the alchemical item itself had been damaged, or the power source sustaining its effect had been completely depleted.
The concept of a power source was somewhat like a battery. It existed to activate an effect, replenish it, or keep it running.
Generally speaking, the power sources used by the vast majority of wizards were magic crystals.
The power furnace carried a somewhat similar meaning to a magic crystal. By burning the power furnace, it could continuously supply the bone leopard with energy. Thus, in Angel's view, a power furnace was much the same as a power source in terms of energy output.
But as Boiling Gentleman explained the power furnace further, Angel discovered several obvious differences. The objects acted upon by power furnaces were all living creatures.
The objects acted upon by power sources were basically never living organisms. Even certain flesh-and-blood puppets forged by mechanical alchemists with power sources as their cores could only be considered cyborgs, not truly
