For Milton Cheney, spending more than five million years to complete this step was absolutely worth it.
Although over five million years is a long time, it pales in comparison to the advancement he had achieved in his Realm this time.
"As expected, the speed of Spiritual Power Transformation is extremely fast."
Inside the Cultivation Space, Milton Cheney, seated in a meditative pose, muttered to himself.
Just as he had anticipated, after he chose to make a Breakthrough to the Eight-Spirit Realm, the initial stage of Spiritual Power Transformation indeed didn't take much time.
For a normal Seven-Spirit Realm Cultivator, completing the Transformation of all the Spiritual Power within the Spiritual Body in over five million years is definitely considered extremely fast.
Of course, this was merely the beginning.
After all, merely transforming one's Spiritual Power is far from enough to break through from the Seven-Spirit Realm to the Eight-Spirit Realm.
