Lin Yu had a fairly good idea of what level Pillar-level Demons were at.
Although within their own territories in the Abyss, these Demons could be said to rival gods, with little difference between them and true gods.
But once they left their territories, they were basically just Chosen of God who were somewhat stronger, or as powerful as ordinary Demigods.
Especially outside the Abyss, the effects of their reduced strength and suppression were even more severe.
In the human world of Night Valley alone, there was a record of the Eighth Pillar's true body descending into the human world, only to be kicked to death through the joint efforts of the three popes. As for projections and incarnations, there were countless records of them being defeated single-handedly by human experts. Their strength was probably equivalent to that of a slightly stronger Monarch-level being.
Converted to Player strength, a Pillar-level Demon within its territory could roughly be regarded as "Tier 5." But once it left its territory, it was basically equivalent to "Tier 4." If it went outside the Abyss and descended through a Projection, or was summoned, it would be even less capable of displaying its true strength.
Although Hershakanus had crossed over from another world, and Lin Yu's [Guest Appearance Invitation], this fictional [Item], was so powerful that it had forcibly given Hershakanus the chance to open a domain, allowing it to display Demigod-level strength, the disadvantage of crossing world barriers still remained.

After all, Potassium Chloride and White Sand were both top-tier "Tier 3" beings. They were absolutely not weak—when Players faced the natives of various worlds, even existences that were nearly gods, they still possessed the natural advantage of methods
