This is because members of the Mortal Races are not Elemental Life forms, and they wish to transform into complete Elemental Life.
In that process, they are inevitably assimilated by the Elemental Rules.
If anything goes wrong, a High Tier existence might turn into a puddle of mush during the breakthrough, and the parts of their body that have already undergone Elementalization will return directly to the world.
Therefore, on the Oakland Continent, anyone who can reach Tier Nine is undoubtedly a true cultivation genius, someone with great perseverance, or incredibly lucky.
And after reaching Tier Nine—no, to be precise, upon reaching the Tier Nine Peak.
The only part of these existences that has yet to undergo Elementalization is always the head! There are no exceptions.
Only when the head undergoes complete Elementalization can a Tier Nine existence truly become a Saint Tier existence.
