Lin Feng knew that Inner Strength cultivators could be divided into Innate and Acquired types.
Cultivators below the fourth layer of Inner Strength were known as Acquired cultivators. The Inner Strength they utilized was cultivated postnatally and was limited in quantity. Often, after an intense battle, they would require a long rest to fully replenish their Inner Strength.
However, Innate cultivators at the fifth layer and above could maintain a constant state of abundant Inner Strength. Even after an intense battle, their strength could be sustained for a long time. This was a fundamental difference. An Innate cultivator with five layers of Inner Strength could potentially fight ten Acquired cultivators at the fourth layer!
Is this unremarkable old man, who looks like an obstinate rock, actually an Innate expert?!
