Even a seven-star powerhouse cannot resist the temptation of food after being hungry for hundreds or thousands of years.
However, Su Yu initially thought that these people would indulge for hours without stopping.
Su Yu was prepared to step in and stop them after they had eaten enough, to prevent them from overeating and getting sick.
Yet, the meal ended rather quickly.
After about ten minutes, they all simultaneously put down the food in their hands, although their expressions were full of reluctance.
Su Yu was puzzled by this sight.
Then he used the Power of Machine God to examine past destinies and discovered that these people had undergone training.
What to do if they one day get to eat normal food?
The rule was not to eat too much since normal food was like "poison" to them; consuming too much could be deadly.
They could eat small amounts and gradually adapt, but they must not overeat.
This training was arranged by the elders.
