The facts proved that Xiao He's approach had been correct.
The beasts of the Primitive Plane had primarily been composed of vitality, supplemented by a small amount of active cells.
Now, after their transformation, their method of evolution had become vastly different from before.
First, the greatest change was that they treated active cells as containers, while vitality had instead become the filler.
Second, they had also gained limitless potential like humans.
Back on the Primitive Plane, a beast's level had basically been fixed from birth.
If one sentence were used to describe the earliest beasts, it would be: "Dragons begat dragons, phoenixes begat phoenixes, and a mouse's son knew how to dig holes."
But now, as long as the environment allowed it and resources were plentiful, beasts could break through the constraints of their existing active cells.
The general concept was roughly similar to a Soul Master's breakthrough in realm.
Of course, after conducting data surveys, the research institute had also discovered another rather interesting subject.
That was, beasts with growth potential did not necessarily possess intelligence.
Simply put, first-generation beasts would gain intelligence once they reached a certain realm.
Things were different now.
Strength did not equal intelligence. First-generation Overlord Beasts could be defeated by later generations.
Conversely, the latter's intelligence might never surpass that of the former.
As for the reason behind this, the research institute was still studying it.
However, one thing was certain: first-generation beasts and the beasts bred afterward did not belong to the same category.
The relationship was roughly equivalent to that between humans and apes.
The two shared certain fundamental similarities, yet their foundations were vastly different.
Moreover, research had readily revealed that the beasts that appeared later grew extremely quickly.
They did not even require many environmental resources; vitality alone could
