Great Occurrence

Like this, Cain fell into a rhythm. Time flew by like the wind as Cain spurted out a copious amount of blood and slightly advanced his Heaven and Earth path attainment level at each interval.

Soon enough, minutes turned into hours. 

There is no sense of time in the Dragon Celestial Pool. Cain felt as if a whole day had passed, but it did little to affect his mental state. He's already used to the long, arduous process of Martial cultivation. 

But it was finally at this time that a critical change occurred within Cain. 

He felt as if a small particle of glass shattered within his mental psyche, prompting him to completely comprehend just a silver of this Origin energy!

Immediately, Cain absorbed the Heaven and Earth Origin energy through his body, controlling it to flow to his dantian. 

The sliver of Origin energy had no obstruction; it instantly fused with Cain's dantian.
