In the Yellow Cloud World, it's considered the limit for a Cultivator to open up their Dantian with a ninefold Qi Sea Foundation.
If one wants to go further, they must endure heavenly punishment.
This process is extremely perilous, with the potential to fall at any moment.
Thus, throughout history, very few have dared to take this risk.
However, there is always a path forward, and the Cultivators of the Yellow Cloud World can still enhance their Mana through some Secret Techniques.
For instance, enlarging one's meridians is the most common method.
Take Zhang Tao, for example, despite only having ninefold Qi Sea Foundation, he can explode with twelve billion Tiger Power by enlarging his meridians.
There are even a few exceptionally gifted people whose meridians are naturally far larger than others'.
The mana they can explode with is several times that of others.
However, such individuals are exceedingly rare; even the Human King Hall can barely find a few.
