Techniques:
Loving Heart Virgin Mind Mantra
Core cultivation technique of the Yin-Yang Heavenly Pavillion, reserved for young maidens.
Can be cultivated from a young age and has enormous potential and cultivation speed while the cultivator is still virgin.
During defloration it brings huge returns for the couple, and enormously boost both their cultivation during each following double cultivation session.
It's highly advised for the deflowerer to be the cultivator's life partner, as he'd get the bigger boost during double cultivation. Other men can still trigger the boost, but neither he nor the cultivator would gets cultivation returns as high as the ones generated while double cultivating with the deflowerer.

Burning Heart Infinite Passion Core
Ausiliar cultivation techniques that develops a passive skill for the user, enabling them to overdraw their energy even when they have none to spare.
The amount that can be overdrawn is proportional to the user's total cultivation, but the more is overdrawn the more lust would the user feel afterward.
While overdrawing the user would feel the arousal slowly building up but it wouldn't be overwhelming unless doing it for too long, whereas once she'd stop using the techniques the side effects would flare up and the user would become very **** to threats of sexual nature regardless of the partner involved.

Fertile Matrix Fecund Body Cultivation Technique
A female body refining technique focused on cultivating physical prowess rather than one's mind or energy.
It mainly enhances raw strength and stamina with less focus on agility, while at the same time enhancing one beauty and reproductive abilities.
The side effects, or perk depending on the point of view, mainly affects the cultivator's fertily and gestation time. By cultivating this technique, a girl's fertility is enhanced and becomes very **** to ovulation techniques or **** but she also gains control over how long the pregnancy will last.
By default, a successful insemination would being to passively drain her energy to speed up and she can purposefully inject more to further shorten the pregnancy and quickly give birth... or at least it works that way with human children.
Few know that this technique is of demonic origin and designed for breeders... not only it further boosts fertility when mating with a demon, often leading to immediate ovulation, but a successful demonic insemination would trigger the active energy drain beyond the cultivator's control and it can't be stopped till birth.
