If martial artists could somehow increase their fertility rates through various means before their bodies underwent spirit qualification, after this transformation, it became near impossible for them to conceive offspring. For the majority of martial artists, even their innate desires would change after their bodies became spirit-qualified.
The first desires to shift were appetite and sexual drive. Most warriors who completed the transformation of their bodies into a spirit-qualified state preferred pure energy supplements over meticulously prepared foods. They favored things such as elixirs refined from divine herbs, holy springs full of spiritual power, spirit wine brewed from spirit rice, or even just breathing in the spiritual energy of the heavens and earth and absorbing the energy from Earth Spirit and Blood Fiend.
Their hunger and thirst could only be satisfied by these substantial infusions of spiritual power, not by exquisite dishes.
