For half a month straight.
Aside from his routine morning qi refining, Chen Mu spent all his other time reciting the Rootless Sutra.
With every wisp of supernatural power he absorbed, the Divine Embryo could swallow another mass of Netherworld Qi, and the Nine Apertures could take in more Taiyin Qi.
Supernatural power was like some kind of catalyst, accelerating the Heavenly Demon Body's transformation. That was why it required more Netherworld Qi and Taiyin Qi.
"Good thing Yin Spirit Divine Power doesn't need any special vital qi to recover."
The Cloud Mirage Heavenly Demon Body could be considered an alternative kind of Yinling. Yinlings were essentially Yin Soul Monsters. And Yin Soul Monsters were exceptionally unusual—even without food or drink, they could survive for a very long time.
Because of this trait, even without deliberately replenishing vital qi, the Cloud Mirage Heavenly Demon Body and the hundred thousand Yin Souls inside the Five Ghosts Bag could restore their Yin Spirit Divine Power on their own.
Chen Mu felt that Yin Soul Monsters might naturally possess an innate ability similar to the Linglong Heavenly Secret Spell.
That was also why he had an unending supply of Yin Spirit Divine Power every day to refine Netherworld Qi and Taiyin Qi.
"Supernatural power, on the other hand, is a little insufficient." Chen Mu was somewhat dissatisfied.
After reciting the scripture for many days, he discovered that the amount of supernatural power he could draw in each day had a fixed limit. Once he reached that limit, even if he recited the scripture all day, he could not draw in any more supernatural power.
"The upper limit seems to be related to my proficiency in the Rootless Sutra."
Chen Mu summoned the Grey Stone Gate and looked toward one of its entries.
