According to traditional spirit energy training theories, it was best for superhumans to maintain their spirit index between 80 and 120.
It was not good if their spirit index was too low. They would collapse due to fear.
If their spirit index was too high, humans would also lose control due to rage.
Once their index exceeded 200, the cells of the human body would be affected by the violent spirit energy. The mitochondria would operate crazily, triggering an overload of energy. It was very likely that they would go berserk or even spontaneously combust.
For example, the Deification Capsule developed by the monster civilization actually made use of this principle to instantly increase the mitochondria's conversion efficiency in an ordinary person by ten times or even a hundred times. The method burned lives, but it allowed ordinary people to temporarily possess strength comparable to that of superhumans.
