Pain. This wasn't a physical pain, but a mental one.
A tidal wave of pain crashed through his mind. Within moments, Qin Ya's clothes were drenched in cold sweat, yet his expression remained placid, betraying not a hint of his suffering and causing the nearby Ting Xiao Sword Spirit to marvel inwardly.
'Not bad, not bad at all. To endure this much pain on his first time using the Quenching God Array... This boy's mental fortitude is even greater than I imagined.'
Divine Thought, unlike True Essence, cannot be refined using the Heaven and Earth Primordial Qi from the surrounding world. This is because the void contains a multitude of energies—yin, yang, cold, foul, and more. While insignificant compared to the vast sea of Primordial Qi, these energies still introduce too many impurities, making ambient Heaven and Earth Primordial Qi unsuitable for refining Divine Thought.
Divine Thought can only be refined using pure Heaven and Earth Primordial Qi.
