In the Nine Mountains and Seas, the Elder generation always passed down a certain tradition to the younger generation of Chosen of the various sects and clans. That tradition was that when the age of true Immortals arrived, one must remember the saying... preparation is the key to success!
By preparing well and accumulating profound resources, one could explode out with extraordinary power, and open up the most Immortal meridians possible.
Therefore, for generation after generation, people would make preparations for the time when the age of true Immortality arrived. They would hold themselves back at the peak of the Spirit Realm and wait until they could unleash all of their resources to achieve true Immortal Ascension.
Throughout all the years, that was how things were done. However, as of this moment, the Patriarchs of the Ninth Mountain and Sea were somewhat in a daze as they watched what was happening.
