"Resolving a bottleneck is not easy, you don't need to be anxious, bottlenecks can be resolved, unless you are as unlucky as the Seven Stars Hermit, encountering several bottlenecks within a single great realm."
Ice Silkworm True Person said.
The Seven Stars Hermit is one of the Five Immortals of Donghua, coming from a background of Loose Cultivators, facing multiple bottlenecks in every major cultivation realm, and it wasn't until he was nearly sixty years old that he reached the Foundation Establishment Stage.
You must understand that for Cultivators who surpass forty years of age, their vital energy begins to decline, progressing downhill with each passing year. The older they get, the weaker their vital energy becomes and the more difficult it is to establish their Foundation.
