Cui Heng had obtained the method to break through the Sixth Realm of the Immortal World, the Myriad Techniques Return to One Realm.
The principle was very simple. It was to refine the power of laws imprinted on the Immortal Body into the Immortal True Essence.
This was the so-called "Myriad Techniques Return to One".
Now, through checking the Immortal True Essence in the body of the Heavenly Saint Supreme Venerate, Cui Heng discovered that this Immortal True Essence already had a trace of weak spirituality, like a life being nurtured.
It could be said to be a Nascent Soul that was countless times weaker than a real Nascent Soul.
However, even with such weak power, its essence still exceeded the original power of a Golden Immortal.
