It took them more than two hours to absorb the energy spring, not the one hour they initially estimated. It took them this much time because the root of the energy spring was difficult to absorb.
The root was more difficult to absorb than expected because they had the divine flesh of four pathways in their body, not just the divine flesh of just the pathway of undying. The extra divine flesh caused some resistance to the absorption.
But they finally absorbed it. When they did, all the divine flesh of the pathway of undying in their bodies began to glow.
There was also the presence of a seed in their soul space. This seed was the product of the fusion of the roots of the energy spring and the core of the spring of life.
The seed had a core and many roots attached to it. The roots spread out and attached themselves to all six divine flesh of the pathway of undying, thereby creating a connection between all of them.
