"Those with good qualities can be bred multiple times, implement selective breeding, and iterate on the qualities of progeny, replacing those trash inferior genes."
"During the process of the mother nurturing offspring, any issues appearing among mortals should be documented by the Joyful Union Sect. Simply consuming the ungraded elixirs should resolve them. These mothers start reproducing around fourteen years old, and even if they die by thirty, they can contribute sixteen times the population size, so it's not a loss."
"Place the mother breeding bases in Gathering Yin Land. During the Yin Year, Yin Month, Yin Day, Yin Hour, Yin Minute, rely on the Joyful Union Sect's elixirs to impregnate the mothers. Through the array, draw Yin Evil into their bodies during the nurturing process, allowing us to mass-produce Extreme Yin Bodies. This physique is top-notch whether used as a tripod furnace or for demon cultivation."
