Throughout history, there had been countless cultivators who had formed a core. However, none of them achieved a Golden Core phenomenon!
As everyone had different learnings and experiences, their understanding of core formation as well as number of meridians unlocked were different as well…
The many different factors would form various Golden Core phenomenons.
The power formed by the Golden Core phenomenons were different as well. Some phenomenons were so mighty that they could shake the world and form tsunamis upon release.
However, some other phenomenons were relatively weaker.
As the saying goes, a phenomenon is bound to occur when eight meridians are unlocked!
However, unlocking eight meridians was as difficult as ascending the skies itself. Thousands of years ago, including the Founder Master of Ethereal Peak, there had only been a single person who had unlocked all eight meridians.
