After using the Plant Growth four times, Qi Ping felt spiritually fatigued.
However, concentrating on comprehending the "Wood Flame Technique" was still manageable.
This was the limit Qi Ping had discovered during this period.
At the Third-Layer of Qi Refining, whenever Qi Ping used the secondary Plant Growth more than four times, he found it difficult to concentrate on cultivation, which easily led to mistakes.
After breaking through to the Fourth-Layer of Qi Refining, his Divine Soul became stronger, but not enough for five uses; however, using skills four times was now easier.
Therefore, using the Plant Growth skill four times in a peak mental state was a relative limit for Qi Ping to ensure normal cultivation.
Upon finishing cultivating the Fire Spirit Grass, Qi Ping looked at the significantly grown plant and then satisfactorily took out the "Wood Flame Technique" to comprehend it.
