As the streak of purple gas descended, the Virtuous Zen Master focused.
At his current level, it was rarely the case that his powers would be depleted as he absorbed spiritual energy from the Heavens and Earth.
But there were always exceptions. Although spiritual energy from the Heavens and Earth was usually limitless, according to the powers of a cultivator, there would be differences in the efficacy and frequency in the absorption of it between cultivators.
During a set period of time, if the depletion of one’s mana was greater than the rate of absorption of spiritual energy, even an Immortal Soul Stage cultivator would not be able to hold on.
When a cultivator wanted to reach the next level, he would need sufficient mana accumulation.
Cultivating different types of mantras would require different levels of mana accumulation. And the Virtuous Zen Master’s current situation was that his powers had depleted much faster than they were replenished.
