The introduction to the Three Realms Cultivation Method explained its principles in detail.
If one were to compare acupoints and meridians to rivers and lakes, they would be extremely fragile before being reforged. They cannot withstand the impact of Inner Qi. Therefore, a Martial Artist must first use their Qi Blood to reinforce these channels and build up dams, preparing for a qualitative change in their body's energy. This process requires maintaining the Qi Blood reinforcement over a long period.
When a Martial Artist's Qi Blood is insufficient, the fortifications they can build are limited. Even if they wish to break through to higher levels of the cultivation technique, they lack the strength to do so.
The ultimate achievement in the third realm of martial arts is related only to the Martial Artist's own volume of Qi Blood.
