The researcher standing in the control room couldn't help but express admiration.
But what surprised them even more was that Yu Yi's food intake had significantly decreased over the past few days.
You should know that when these changes occur in a person, even consuming an amount equal to ten people's food isn't exaggerated, because the energy conversion efficiency of the human body is very low. Typically, for ordinary people, in order to gain a pound of muscle, one might need to ingest dozens to a hundred times more food in weight.
Over the past few days, Yu Yi's weight increased from 150 pounds to 200 pounds, indicating he might have needed to ingest far more than a thousand pounds of food and protein.
However, Yu Yi's food intake over these days was only around several dozen pounds, not much different from an ordinary person's amount, almost only enough to maintain the basic survival metabolism of a person.
This led them to ponder what Yu Yi's energy source might be.
