Talented intelligent creatures could awaken Super genes. Through various training, the cells would create special power—this was energy. The energy was like a running river; cells and genes were like the stones under the river. As the river grew larger, after days and days of flowing, the genes would start to evolve, gradually becoming perfect. It was like compressing the million years evolution.
Grade A was a benchmark, also called Calamity Grade. It was a high-level power in the galaxies, and Supers fortunate enough to reach this grade were very uncommon. When the genes evolved to a certain level, it would meet an indestructible barrier ahead without exceptions. In other words, 'there was no road ahead anymore'.
