Chapter 76 The Appearance Of Percy

• Scientific research showed that some humans' unnatural superpowers were related to brain waves. Those people might be born unusual, and their brain waves were different from that of ordinary people. When the spiritual energy generated by the brain waves reached a certain level, the spiritual energy would be known as mana.
• Mana possessed boundless power, but this is all theorized by scientists and required further research.
• As of the present, no one had developed their brain cells to twenty percent, and no one had been able to convert spiritual energy into mana.
