The Controlled Dan realm was a very crucial stage for cultivators. If their foundations were not sufficient, then their path would stop there.
Refining a Controlled Dan was the same as refining a pill. The quality of the ingredients was critical, same with the quality of the cultivator's foundations.
Naturally, the stronger the ingredients, the better the pills refined would be. By the same logic, the strength of the dan condensed by a martial cultivator was dependent on the depths of his cultivation!
This was also the reason the gaps between Controlled Dan Heavenly Experts were suddenly magnified. The strong would become extremely strong, while the weak would be exceedingly weaker among the same realm!
It was also possible for the mediocre cultivators to obtain a powerful resource or a fortuitous encounter, forming an extraordinary dan and directly leaping into the clouds!
