The Human Race's Soul Killing Demon Emperor once made an assessment: "In this world, there are two holy lands for Soul Tao Martial Artists. One is the Soul Cleansing Mountain, used to shape the soul; the other is the Luopo Valley, used for Soul Refining."
The soul must be strengthened and, at the same time, refined.
Hong Yuan, through the constant devouring of Soul Beasts, had made his soul grow stronger, but this had also tainted it with many impurities.
Being in the midst of the Heart-questioning Trial was one thing, but if he were to return to his own body, just calming the conflict between his soul and flesh would be a huge ordeal for Hong Yuan.
He would need to sleep for years on end to survive this calamity and quell the unrest between his ill-matching soul and body.
