The evolution of the human body is a process that spanned millions of years from ape to man.
And for an ordinary person to break through to the Anjin Realm is to undergo a second evolution.
One can imagine how much the ancient predecessors valued this evolution.
If one could take another step further and break through to the Strength Transformation Realm, that would complete the third evolution of mankind.
Above Strength Transformation, the density of the skin and bones reaches an unimaginable realm.
Moreover, the use of mental strength and the development of the brain are further enhanced.
Each completed evolution signifies humanity's step toward a higher stage of being.
One's own power and intelligence would increase by tens of times.
Yang Fei knew these principles.
However, even he did not understand where these deepest martial arts secrets in his brain came from.
Everything that happened before he turned eighteen was like an unsolvable secret.
