A good amount of time went by, when one of the more burly subjects suddenly showed a spike in his absorption rate, with the energy level in his tank falling sharply.
All attention went to him as the scientists tried to maintain a level of influx of energy that would not put his life in jeopardy.
Hearts hung in the air until he stopped, and the energy in the tank returned to an idle behavior of a fish taking a stroll.
The crowd was surprised, and even the scientists forgot to cut off the influx of energy that seemed to have become useless.
"Lower the flow of energy and if its level remains the same until it is cut off, start draining it."
The professor snapped out of his surprise, but he kept his voice low as he gave the order as if he was afraid of disturbing the man who was showing bits and pieces of earth on his skin.
