After dividing up the treasures, everyone went into seclusion to cultivate in turn.
Chen Nianzhi also began refining the innate qi and cultivating the Innate Primordial Chaos Indestructible Body.
Without breaking through to the Heavenly Immortal realm, reverting one's physique to the innate state was a rather lengthy undertaking. Even with Chen Nianzhi's current cultivation, merging a strand of innate qi into his fleshly body required ten thousand years.
Fortunately, reverting one's physique to the innate state did not require a death seclusion. Chen Nianzhi could merge the innate qi while cultivating in the Five-Elements Microcosm.
However, after Chen Nianzhi had cultivated in seclusion for three thousand years, he discovered that the Innate Enlightenment Tea was no longer sufficient.
This Innate Enlightenment Tea matured once every ten million years, yielding only ten portions. It was simply not enough for the Chen Clan's ten half-step Heavenly Immortals.
Furthermore, the Innate Spiritual Water produced by the Heaven-and-Earth Primordial Qi Bottle, a low-grade innate treasure, was no longer very useful to the Primordial Ancient Tree. It could not hasten the tree's maturation and was ineffective on the Innate Enlightenment Tea.
Left with no choice, Chen Nianzhi had to expend a strand of Innate Primordial Purple Qi to advance the Heaven-and-Earth Primordial Qi Bottle.

With the Heaven-and-Earth Primordial Qi Bottle, Chen Nianzhi spent fifty million immortal sources to ripen fifty portions of Innate Enlightenment Tea, allowing the Chen Clan to continue cultivating.
Not long afterward, Chen Nianzhi opened the furnace again and refined seven batches of Yin-Yang Enlightenment Pills, producing a
