At this, Chen Nianzhi could not help but reveal a wry smile.
Supreme Unity Gold Essence was a top-grade immortal metal, no less valuable than immortal metals such as Dragon-Pattern Black Gold. Even a small amount of Supreme Unity Essence Gold was exceedingly precious.
Top-grade immortal roots were even more astonishingly valuable, for such roots were already the limit of acquired spirit roots and the finest treasures for refining fourth-grade Heavenly Pillars.
They were several times more precious than top-grade immortal treasures and truly difficult to find. Thus, when most Earthly Immortals broke through, the fourth-grade Heavenly Pillars they used were only made from high-grade immortal roots.
Chen Nianzhi had been an immortal for several thousand years, yet he had never seen a top-grade immortal root. This showed just how precious such roots were.
Seeing that they could not replicate the treasures, Zhenyuzi could not help but speak.
"Since we cannot find Supreme Unity gold-foil paper, nor any Dao-Teaching Paper of the top-grade immortal treasure level, let us divide these seven immortal scriptures."
"That is our only option."
Chen Nianzhi nodded and began examining the seven top-grade immortal scriptures.
These seven immortal scriptures were all the sect-defending inheritances of the Yin-Yang Immortal Sect, and three of them were cultivation techniques.
These three immortal scriptures were respectively named the Lunar Soul-Refining Method, the Solar Body-Tempering Art, and the Yin-Yang Void Scripture.
After reading them, Chen Nianzhi could not help but praise, "The three half-step Earthly Immortals of the Yin-Yang Blessed Land truly were people of extraordinary talent."
"Indeed." Zhenyuzi nodded, then said, "This Pure Yang Body-Tempering Scripture has quite a few unique aspects."
It turned out that these three methods each followed a different path toward becoming an Earthly Immortal.
The Lunar Spirit-Refining Method focused on the soul and Dao Fruit.
