The Soul-Splitting Technique had a single, straightforward function: it could split off a portion of a Soul Body.
This mystic art did not have the "Curse Dao" prefix. Chen Miao guessed that it might be a general-purpose mystic art that just happened to appear during this incident.
A Split Soul is a divided Soul Body.
That Soul Body could belong to the caster or to a ghost.
Splitting a Soul Body was no simple task.
If the target was a ghost, poor control could push it beyond its limits, causing it to collapse during the splitting process and scattering its soul into oblivion.
In a sense, this mystic art could also be considered an offensive ability.
But using a Split Soul was a very slow process, so it could not serve as a conventional attack in combat.
If the target was the caster's own soul, even more precise control was required.
Damage to one's own Soul Body could cause mental debilitation or insanity in milder cases, and outright death in severe ones.
Judging by that, anyone who dared to use the Soul-Splitting Technique was either a lunatic or utterly ruthless.
As for whether the Soul-Splitting Technique could be used on humans other than the caster?
No!
Before a person died, their three ethereal souls and seven corporeal souls were bound far too tightly to their physical body for a mere Soul-Splitting Technique to separate them.

As for what the separated portion of a Soul Body could be used for?
That depended on the specific need.
If Chen Miao had not obtained anything related to Six Livestock, he would not have known what to do with the separated soul even if he wanted to try soul splitting.
