Legend had it that during the Ancient Age, the Creation Pool had gathered the Power of Creation of Heaven and Earth, meaning it could be used continuously to cultivate geniuses. It was the foundation of a large sect.
During that time, the Creation Pool was built to cultivate the disciples of the younger generation. It was used precisely so that the Ancient Age Creation Sect would be full of strong and talented practitioners. The might of the Creation Sect back then was equivalent to that of an entire realm now.
The Path of Creation mentioned by the Huatian Palace was actually a place that the Creation Sect had built to assess their disciples. Once the disciples completed the challenges, they would be able to enter the Creation Pool and receive enlightenment from it.
