Samuel finally had some headway in learning what he was doing with Elizabeth. The amount of knowledge he earned directly from Belial was cursory at best, but he did get access to a full treasure trove of books and scrolls, all giving him deeper insights into the cauldron system, which was deeper than he was led to believe. He had assumed the cauldron system was a very poorly understood niche with very little research done. The library he had access to imitated his thoughts with barely anything on the subject.
He was thankful to Belial for handing him so many personal books and scrolls when he had asked for more information. All he had asked in exchange was to be more open to the cauldron path, something he was already trying to do. Now he was trying to gorge as much knowledge as possible in an out-of-the-way room while Elizabeth mingled with her peers before the day was up and he needed to return the mountain of books and scrolls. As it turned out, his low status in the sect had hurt him once again.
Due to very twisted politics, he did not bother trying to get into them, they are held in the deeper inner sect library halls to more carefully regulate their circulation more.
The foremost myth that this broke was that a virgin or a specific form of cultivation was necessary. That was not actually true. What was necessary was a constitution that was naturally present in all virgins and those who practiced the 'cauldron' arts. In that same vein, he had extrapolated something a touch sinister. The whys and hows of a cauldron constitution were explained in extreme detail, to the point that even novice cultivators could use the information to become cauldrons. What he had found out was that his 'World Seed' could do a similar thing. One of its core principles was to make his constitution 'perfect' for him. It also made other people 'perfect' for him. This was another way of saying, it turned others into receptive cauldrons who only needed that final push. Once that happened his essence kept refining the 'cauldron' to be even more effective at handling his essence. His breakthrough destiny inadvertently had the effect of a 'cauldron' art. He thanked Lucia for pushing him in this direction. Who knows what havoc he would have caused otherwise? At least there was enough study done to make it a legitimate immortal path.
That part surprised Samuel, there were actually quite a few people invested enough to make an entire path out of being a cauldron, there were even entire sects dedicated to being cauldrons. They even listed many valid benefits of being a cauldron. Not the least of which was that the 'cauldron' was not tied to only having sexual intercourse with their respective 'master' and could have sex with other masters for benefits, that part irked Samuel, much to his surprise, and he instinctively had his soul sight on Elizabeth the whole time there were in the deprave establishment. She did not engage with any of the masters but instead took to chatting and socializing with her peers. That had felt agreeable to him.

On his side, there were actually quite a few things he could do. The foremost of which was shaping her constitution to be more receptive to his essence, something he was doing passively but also being influenced actively. If cauldrons were saturated enough with their master's essence, they could skip steps and directly reach the stage of the masters. The process was not an easy or fast one, but compared to reaching it normally even with his previously perceived cauldron growth rates, the process was ten times faster.
That begged the question as to why this was not more widespread, the benefits outweighed the cons 3 to 1 even if he weighted the partial lich's phylactery nature and the inability to move on to other masters ever exceptionally heavily. There was more to this, which he suspected was some sort of esoteric reason so it was immediately pushed out of his mind. No need to get involved if it was necessary for his and her growth.
His thoughts were stopped abruptly as a head shoved its way into his crotch taking in the scent like it was some sort of addictive drug. The thing that stopped him was not that she was about to blow him, that was the norm in this establishment. Any master inside was under a 'free use' clause based on their sexual orientation. Women had to keep their breasts out in the open and the men their phalluses. Disciples in this den could freely use them as they pleased, but the master was not under any obligation to provide them with any essence. He had been steadfast and despite the dozen or so attempts he had yet to ejaculate once.
What surprised him was the nature of her existence.
Beastmen or more commonly referred to as demi-humans were a very average sight in the mortal world, but their nature was very tribal. They mostly joined sects specifically for demi-humans. The ones that joined humans were usually the 'loner' variants and even then were rare. And even that was not the distracting aspect of the woman 'digging' into him.
The woman under him was a unicorn. A mythical demi-human variant, that was so rare that they had an entire saying revolving around them. Most became alicorns or a 'corrupted unicorns' by the time they hit maturity.
The one beneath him was still 'untouched', meaning her unique constitution was still in place. While inside a home literally called the 'den of depravity', Belial's naming conventions were very on the nose.
His curiosity was piqued, why was such a pure creature here, and how the fuck had she preserved her purity?
