The evolution of origin ability was common in society.
Regardless of whether one was a human or a berserk beast, they would both follow the same process. However, in order to distinguish between these two, humans adopted a more acceptable method and called their process the integration of origin ability! On the other hand, humans referred to the process in the berserk beasts’ kingdom as variation.
That’s right.
As every human entered high school, they would undergo the integration of origin ability—this was the first evolution of origin ability! For every berserk beast, when they were affected by the influence of origin ability, they would evolve into berserk beasts from ordinary animals. This was their first evolution of origin ability!
Evolution was the theme song for human advancement.
And this had always been true from the beginning until today.
