Fortunately, Wang Ye has developed a certain capability for heat storage through evolution. The amount of heat stored within his body, consisting of a hundred trillion cells, is comparable to the total caloric intake of an average person's lifetime. Therefore, as long as the exercise is not too intense, he can maintain it for around half an hour.
However, after half an hour, he must immediately surface and absorb sunlight, or he will face life-threatening energy depletion.
But such situations are virtually impossible for Wang Ye, as his brain domain development allows him to precisely monitor various bodily indicators down to the hundredth decimal place.
Thus, unless there's an emergency, he won't find himself depleted of energy to the point of death.
