That day, Krune and Heavin compiled all the information about the Soul Cultivation Technique and passed it to the others. Of course, Krune and Heavin had to work on it for a few days to alter some of its properties. After all, a Divine Soul is not the same as the Normal Soul. They have their own differences that had to be accounted for. Fortunately, it didn't take long since the main issue of the technique was already resolved.
Different from Heavin, the others would need to start from the beginning, though. The reason Heavin could start from the 3rd Realm was basically that this Realm allows you to create Elemental Source Energy. Since his Divine Soul is already capable of it, he jumped the first two without a problem.
