Martial arts practitioners emphasize training during the three nine-day periods of winter and the three ten-day periods of summer, but in fact, most fighters, once they have laid the foundation and entered the third-rate realm, will not do so anymore because, quite simply, the human body needs nurturing.
Endlessly toiling away in practice does not lead to much progress, but rather can harm the body, as the growth of true energy requires energy replenishment. The human body is an extremely precise machine; once you overdraw on a particular element, side effects are bound to occur.
Therefore, for the sake of health, ninety percent of warriors rhythmically cultivate their skills after reaching the third-rate realm instead of relentlessly toiling away.
This is aside from those with wealth to replenish various cultivation supplies, or those with family medicinal formulas, allowing them to concoct their own remedies, and these people make up the remaining ten percent.
