Li Fan in this life had once tried to categorize the True Immortal Seal Characters he had encountered.
But that was from the perspective of the specific powers of various True Immortal Seal Characters, such as destruction, edicts, enhancements, and so on.
However, within the Broken Immortal Tower at the End of the Star Sea, it was from another novel perspective.
That is: whether the [Taoist] depicted by the True Immortal Seal Characters has been or had been occupied by a True Immortal.
According to the many documents within the Broken Immortal Tower, these different True Immortal Seal Characters— the difficulty and danger of starting on the Immortal Way through them—are utterly incomparable.
If a True Immortal already occupies the Path, anyone who foolishly tries to enter the Path through the characters will, at the moment of "achieving the Tao," vanish into ashes, disappearing without a trace. No matter how powerful or talented, they could not avoid this fate.
