Of course, the Small Thousand World is just the Small Thousand World, its potential may not be sufficient, but the essence of its status is there. If a powerful being could seize the Heavenly Authority of such a world, they would indeed be able to walk the Earth Immortal Path and certify as a True Immortal.
If such news had come in the past, it would likely have attracted the attention of countless strong beings and might even have triggered a fierce slaughter without surprise.
However, after the Enthroning of Gods, most of the beings who are qualified and have the chance and hope of becoming a True Immortal already hold a Divine Position; they are not worried about their lifespans being insufficient for the short term.
In such a situation, without the pressure, even if they wish to step onto the Immortal Path, they would not just accept any opportunity that comes their way; they aspire to reach even stronger Realms.
