If human cultivation meant bringing one's own Soul Power frequency X closer to a Soul Beast's frequency Y, then that theory was obviously untenable.
Because that would mean the ultimate goal of human cultivation was to become Soul Beasts, yet reality was not like that.
Whether human or Soul Beast, the goal of cultivation should be to become a god.
Thus, Chen Feng guessed that between the Soul Power frequencies of humans and Soul Beasts, there was another extraordinarily special frequency.
That was the frequency of "gods."
Only this frequency could resonate with the energy frequency of the Douluo Plane itself.
Or, to put it more appropriately, achieve resonance.
After resonance formed, "gods" could command immense power within the Douluo Plane, even transcend this plane and enter the God Realm.
All other Soul Power frequencies, meanwhile, would be disrupted by the plane's own frequency.
Its external manifestations were various restrictions, such as the cultivation bottlenecks of humans, as well as the heavenly tribulations Soul Beasts faced and the rule preventing them from becoming gods.
Looking at the triangle on the paper formed by three terms, Chen Feng felt as though the fog before his eyes had instantly cleared, leaving him with the sensation of clouds parting to reveal the sun.
In his view, the Spirit Power Frequency Hypothesis explained many things.
For instance, why did soul masters encounter a bottleneck every ten levels of Soul Power growth and require a spirit ring before they could continue advancing?
That was because, as soul masters cultivated, the energy within their bodies—Soul Power—continued to increase.
However, the amount of energy a given frequency could contain was limited, so it had to undergo a frequency shift before the energy within the body could continue growing.
*No, that still can't explain why one can continue
