Dual Cultivation was a type of cultivation system, wherein male and female cultivators pair up and cultivate through intercourse.
Though a lot pursued it casually, many had Dao Partners—partners with whom they exclusively cultivated. These bonds were formed for various reasons, from sexual compatibility to affinity and even genuine love.
Such was the case for Xinyi. She and her partner were deeply in love. Even better, they had good compatibility with a certain Dual Cultivation technique.
Xinyi comprehended the Law of Creation, while he comprehended Destruction.
Together, they used their opposing law energies to cultivate, the contact agitating their energies, causing them to push against each other and rush to their energy cores faster. This saturation accelerated their comprehension, their cores absorbing essence rapidly while their souls processed the laws' working processes.
