In the Eastern Continent, there were countless hidden realms.
They were often tucked away in small spatial cracks in places where spiritual energy was dense.
Some of these realms were tightly controlled by powerful cultivators and opened only periodically.
Because secret realms were so common there, even less talented cultivators had a good chance at making breakthroughs to the Nascent Soul stage or higher.
To control the power balance and prevent a flood of Spirit Ascension stage cultivators, elite sects in the Eastern Continent placed powerful Immortal-level restrictions on these realms.
As a result of their actions...
Every five thousand years, very precious secret realms would appear, while others became almost impossible to find.
Despite this rarity, new secret realms often emerged in different locations, sometimes more quickly than the upper-class sects could manage.
