Those late-stage Earthly Immortal existences were all the cream of the crop among Earthly Immortals. Nearly all of them wielded orthodox-grade Heaven-Opening divine abilities as their trump cards, and had cultivated them to the realm of great accomplishment.
Chen Nianzhi's four natal divine abilities were still merely orthodox-grade. They had not even been cultivated to the Heaven-Opening realm, so they certainly could not match the natal divine abilities those ancestors had cultivated for millions upon millions of years.
"My offensive power should surpass that of an ordinary sixth-level Earthly Immortal, though my control is somewhat lacking. Taken as a whole, my combat strength is probably around the level of a fifth-level Earthly Immortal."
"If I can cultivate the Primordial Unity Qi and deduce it to the wondrous realm..."
Chen Nianzhi murmured inwardly, and his eyes could not help but shift slightly.
As a natal divine ability Chen Nianzhi had created himself, the Primordial Unity Qi could theoretically reach the domain of wondrous divine abilities so long as it fused five kinds of supreme source qi.
By then, Chen Nianzhi's offensive power and defensive methods would likely enter the domain of seventh-level Earthly Immortals. Even considering the shortcoming of his insufficient mana, which made prolonged battle difficult, he would probably be comparable to a Six Tribulations Immortal.
And how powerful was a Six Tribulations Immortal? An Earthly Immortal who had broken through as a Nine Tribulations Immortal, after resolving the weakness of insufficient mana, was in truth only at this level.
At this thought, Chen Nianzhi pondered aloud, "For my Primordial Unity Qi to advance further, I need five kinds of supreme source qi."
"I have now gathered the four kinds of Geng Metal, Jia Wood, Bing Fire, and Ren Water. I only lack the final portion of Wu-Earth source qi."
