The cultivation techniques in the Land of the Four Pillars were even more monopolized than in Shenxu Heaven during the time it was called Jiawu Realm. Therefore, even if a loose cultivator had immense potential, it was impossible for them to remain unknown if they managed to attain superior cultivation techniques.
Especially here in the Land of the Four Pillars, there was a mystical artifact known as "Nine Spirits Eye."
This artifact did not possess offensive or defensive capabilities; it was said that once a Heavenly Book descended to the world, a master of artifact crafting enlightened a method of refinement from the Heavenly Book.
Once refined, it could monitor the level of cultivation of cultivators within a certain range.
That also meant that as soon as a loose cultivator successfully achieved their certification, entering the ranks of the Immortals, the local cultivating families would undoubtedly be the first to know of this information.
