Chen Nianzhi still had one breath of Innate Primordial Purple Qi. As long as he fused it into the Gale Gourd Vine, the Gale God-Slaying Gourd would gain the power to injure Seventh Tribulation Celestial Immortals.
However, a Gale God-Slaying Gourd that was merely a mid-grade innate treasure would likely only be comparable to the Heavenly Separation Twin Swords when wielded together.
Chen Nianzhi already possessed the Grand Five-Element Pure Yang Divine Thunder and Taiyi Voidrealm Sword Qi. This item could not exactly be called useless to him, but it was not particularly useful either.
Most importantly, what Chen Nianzhi most wanted to advance was not the innate Gale Gourd Vine, but the Innate Heaven-and-Earth Primordial Qi Bottle.
The Innate Heaven-and-Earth Primordial Qi Bottle possessed supreme wondrous uses. It could cultivate Taiyi immortal roots and even accelerate the growth of Primordial Ancient Trees. That was the foundation of Chen Nianzhi's path to Dao.
According to Chen Nianzhi's calculations, if the Innate Heaven-and-Earth Primordial Qi Bottle advanced into an innate ancient treasure, the Innate Spiritual Water it produced would contain a trace of the profundity of the Heaven-and-Earth One-Qi Great Dao, becoming Innate Heaven-Earth One-Qi Water.
That Innate Heaven-Earth One-Qi Water might help Primordial Ancient Trees break through their bottlenecks and advance into mid-grade Primordial Ancient Trees.
If all twenty-four of Chen Nianzhi's Primordial Ancient Trees advanced to the mid-grade, his cultivation speed would surely soar by leaps and bounds. Breaking through one level of cultivation every million years might no longer be a dream.
"To advance an innate treasure into an ancient treasure requires at least six strands of Innate Primordial Purple Qi. At my speed of refining one strand every two hundred thousand years..."
"It seems it will only take a million years."
Chen Nianzhi murmured slowly, ripples stirring
