Samuel was extremely curious, as he had not been in a very long time. The animal that was using him right now was a walking contradiction.

First, she was still a unicorn so her maidenhead was still intact. Keeping that whole was a myth in a sect that did not cater specifically to saving your virginity. It was true that he did not lose him till about two centuries in but he was a master, the being in front of him was a disciple and she was at the essence condensation stage. Scissoring did not work and if she got there by blowing people all her life, she had to either blow an origin spirit nearly every day for a year straight to get enough true essence into her essence heart to get to essence condensation or she was over a unicorn over 100 years old and given that she lacked the 'stacked' figure attributed to any of the equine demi-humans he doubted it.

Second, her essence felt... unique for lack of a better word. Granted, the type of cultivators he met was rather limited given his reclusive nature but even still it was intriguing, nonetheless. His soul sight was heavily augmented due to his breakthrough destinies and he could easily decipher most essence formations, but not hers as it was so unique Samuel lacked any information he could reference to draw even an educated guess.

Third, and probably the most curious, he was feeling aroused. That might not mean much, but he prided himself in his extreme control over his own body. Once he understood what Elizabeth was doing to him, he clamped down on it very quickly and now could call upon and dismiss it on demand. Right now, he was feeling very very raunchy, to the point he wanted to flip the unicorn over and shove his manhood inside her maidenhead and permanently mark her.

That, however, was not going to happen. His control over himself was just too great to fall for such random flights of fancy. But, he wanted to study this bundle of mystery further and there was a very easy way to get her to stick around and this was another thing he could do on demand. He was going to give her what the rest of the disciples had failed to coax out of him.

As the unicorn was slobbering over his cock, he waited till she had the whole thing in her mouth, the moment enough of it was in that he felt confident there would only be minor spillage, he let it release. The unicorn's eyes widened in surprise before glassing over, she lacked any gag reflex because even though she was out of it, her throat somehow managed to still guzzle down all of it without any drop being wasted.

The next thing that happened truly surprised the nascent soul cultivator. An hour's worth of his life was shaved off from his total vitality. An hour was such a stupidly small amount. Especially, taking into account the millennia he could spare, and if he ever managed to get into soul formation it would become unlimited.

But the fact she could take any at all was worth investigating, she had also managed to trump his natural defenses which were 3 full stages higher than hers and the effect was extremely subtle, to the point that if he was not carefully monitoring the transferal of the essence, he would have missed it.

The whole ordeal became more and more curious. Now he could do two things, use his power and force her to obey his demands using his status as a master. Or directly ask her what, why, and how she was doing this.

He was already peering into her with soul sight but he could find no discernable differences in her soul or essence. Not even his essence which liked to rampage inside anyone it entered. Not in a bad way, at least if they were already cauldrons or were not exposed to them for long periods. In fact, as the guard could attest, his essence was all benefits, which begged the question.

Where did all of it go?

The only way he could dig further was by shoving his sensory abilities into her, which was not a comfortable experience. It was also frowned upon in most righteous sects because it tended to severely damage the essence circuits unless the one invading is very careful. This only became more pronounced the wider the gap between the invader and the victim was.

Samuel was not so curious to do something heinous like damage the future of a random disciple who bore him no ill will. So, all that remained was to wait until the disciple woke up. To that end, he brought out one of his 'World Seed' pills, one that was designed to rejuvenate the target. People might say he was being wasteful, after all, the pill in his hands was effective on people up to the nascent soul stage but to him, it was barely a cost. After all, the base of it was simply his extremely powerful breakthrough destiny, something he had a statistically infinite stock of.

So pop went the very desired pill for the sake of one master's curiosity.
