However, despite the immense power of such a secret technique, many elders of the Saint Sect forbade their disciples from cultivating it.
This is because, if this evil technique is to reach its maximum power, it requires consuming life, and the more lifespan it absorbs, the greater its power becomes.
Possessing a powerful weapon gives rise to a desire to kill, not to mention that this cultivation technique itself affects one's mind.
This leads to almost no demon cultivator learning this technique being able to resist not consuming their lifespan. The vast majority end up with heads full of white hair and worn appearances at a young age due to frequently using this technique in conflicts with others.
There was even a case where a Core Formation Cultivator exhausted as much as three hundred years of lifespan in one breath!
Of course, the battle result was shocking; with a single cut, he killed a Nascent Soul stage cultivator, shocking the entire Cultivation Realm.
