The Profound Underworld Earth Technique was relentlessly operating within him, and his earth-attribute mana was increasing rapidly, gradually approaching the limit of Qi Refinement.
It only took the span of two quarter-hours.
"Buzz!"
Suddenly, Su Yu's earth-attribute mana was rapidly collapsing and transforming, much like a ball of earth, which, after accumulating to a certain degree, suddenly compressed and refined itself. Gradually, a Foundation Establishment seed was formed, having shrunk nearly tenfold in size.
This Foundation Establishment seed resembled a piece of thick earth, exhuding an immense and profound aura.
Simultaneously.
The aura emanating from Su Yu underwent another change.
As the Golden Cicada Technique operated, a brilliant golden glow enveloped his body, and his mind was clear and void.
