Acquiring Land
Davis spent the entire night with Fiora as he made love with her and later slept with her.
The exhaustion utterly disappeared, his soul force was fully restored, and his soul essence also regenerated to ninety-nine percent with him using Fallen Heaven. He used Fallen Heaven after he restored his soul essence to ninety-five percent so that he could raise it faster.
After all, even if he could restore soul essence with his own life energy, restoring soul essence after ninety percent becomes incredibly difficult and time-consuming, especially after ninety-five percent, and the last one percent is nearly impossible to restore unless he used Fallen Heaven.
However, Davis didn't restore the last percent. He might go to ninety-nine point nine percent, but never fully hundred as that was a full circle, and when using Fallen Heaven, he knew never to go complete a cycle.
