Yinyang Mirror, Grotto-Heaven Blessed Land

Time flowed on, and three thousand years passed in the blink of an eye.

Yuan Yan suddenly opened his eyes, profound Great Dao fluctuations swirling within them. His figure moved, and his feet lightly stepped upon several nodes of the grand formation, causing mysterious Dao rhythms to circulate.

"Break!"

Yuan Yan gave a soft shout and pointed two fingers before him with his right hand. A beam of Yinyang Divine Light burst forth.

"Buzz!" The innate grand formation spanning hundreds of millions of miles rippled like water before vanishing in an instant.

At the same time, the treasure protected by the innate grand formation appeared before Yuan Yan.

It was an ancient mirror engraved with a Taiji Yin-Yang fish, cloud patterns, and the Eight Trigrams.

Immortal light flowed across the ancient mirror, overflowing with Dao rhythm. The mirror was divided into two halves, one red and one white. The red side emanated a gentle red radiance brimming with vitality, while the white side emitted a cold white light suffused with deathly aura.

"What a treasure!" Yuan Yan's eyes lit up. This mirror exuded an exceedingly profound Dao rhythm of Yin-Yang, life, and death, making it an exceptional match for his own Dao.

Moreover, judging from its aura and Dao rhythm, it was at worst a high-grade innate spirit treasure. After climbing Mount Buzhou for tens of thousands of years, he had finally gained something worthwhile.

With a thought, he raised his hand and drew the ancient mirror into his grasp. Yuan Yan immediately sent his divine sense into it and initially imprinted it with his true spirit mark.

At once, Yuan Yan learned the origin, grade, and functions of the innate spirit treasure before him.

This mirror was the Yinyang Mirror, a high-grade innate spirit treasure with thirty-six innate divine restrictions. It contained the Great Daos of Yin-Yang, life and death, reincarnation, karma, and more.

The Yin side of the Yinyang Mirror emitted white light that locked onto karma. Whoever it shone upon would die. It specifically annihilated primordial spirits and true spirits; even a Great Luo Golden Immortal would find it extremely difficult to withstand without a defensive spirit treasure.

The Yang side emitted red light that could bring the dead back to life, heal Dao wounds, and restore the physical body, primordial spirit, and even the true spirit.

If activated together, they could further evolve into Life-and-Death Reincarnation Tribulation Light. Not only did it possess the powers of both the Yin and Yang sides, its might was several times greater.

Yinyang Mirror... Could this be the one Yuanshi Tianzun bestowed upon his disciple Chijingzi? Yuan Yan guessed.

If that was true, Yuanshi Tianzun should have obtained the Yinyang Mirror while climbing Mount Buzhou. However, because Yuan Yan had been born ahead of time, he had intercepted it first.

Forget it. No matter what, this innate spirit treasure belongs to me now! Although the Yinyang Mirror's offensive power is far inferior to the Myriad Dao Primordial Gourd, its healing abilities fill a gap for me. Moreover, comprehending the laws and Great Dao it contains will be of immense benefit to the evolution and perfection of my own Dao.

I've only climbed Mount Buzhou for tens of thousands of years and have already obtained such a treasure. Even if I stop resisting Pangu's pressure head-on, it will still take at least two or three yuanhui for me to reach Mount Buzhou's summit. I wonder what other treasures I'll find next?

As he thought this, Yuan Yan could not help but feel boundless anticipation. He temporarily put away the Yinyang Mirror and continued climbing Mount Buzhou.

Tens of thousands of years later, after advancing a considerable distance once more, Yuan Yan could no longer endure Pangu's increasingly terrifying and oppressive pressure.

If he wished to continue forward, he could only rely on his identity as an innate sacred being born from Mount Buzhou. He would have to stop actively drawing Pangu's pressure with his own Dao to resist it, allowing Pangu's pressure to overlook him instead.

Sensing that he had reached his limit and that excess was as bad as deficiency, Yuan Yan did not stubbornly persist. He ceased actively drawing Pangu's pressure with his own Dao.

Instantly, Yuan Yan felt his entire body grow light. The pressure of Pangu weighing upon his physical body, primordial spirit, personal Dao, and innate indestructible true spirit suddenly disappeared. Though it still existed within Mount Buzhou, it had overlooked him!

Freed from Pangu's pressure, Yuan Yan climbed Mount Buzhou much faster.

Soon, in less than two yuanhui, he was about to reach Mount Buzhou's summit.

However, Yuan Yan suddenly paused and stopped. Then he turned and headed toward his right front.

Ten years later, following an unseen pull, Yuan Yan arrived near an utterly unremarkable pool of water.

The moment he arrived, a profoundly mysterious Great Dao fluctuation rippled outward like waves, revealing a realm gate.

"What is this?" Yuan Yan was slightly startled. However, after communicating with heaven and earth through his primordial spirit and deducing for a while, he understood.

The Primordial World stood at an extremely high level and had birthed many innate spirit treasures and innate spirit roots.

Yet innate spirit treasures and innate spirit roots could not be born from nothing. Their birth required not only one or several Great Daos to resonate to varying degrees and condense innate origin, but also a place rich in innate spiritual qi, Dao rhythm, and spiritual essence to serve as their place of gestation.

Such places of gestation were generally known as grotto-heavens and blessed lands. Blessed lands were locations of innate earth veins and spiritual acupoints, while grotto-heavens were small worlds.

For example, his place of birth, as well as the places where the innate spirit treasures and innate spirit roots he had acquired while climbing Mount Buzhou had been nurtured, were all locations of innate earth veins and spiritual acupoints. They could all be called blessed lands.

What he had encountered now, however, was the entrance to a grotto-heaven. The grotto-heaven's true body was not on Mount Buzhou, but in the boundless void.

Furthermore, grotto-heavens and blessed lands were not as he had originally thought, with grotto-heavens necessarily above blessed lands. There was no strict distinction of superiority between them. A grotto-heaven was not necessarily superior to a blessed land, nor was a blessed land necessarily inferior to a grotto-heaven. Their quality primarily depended on their respective grades.

For example, his place of birth was one of the core spiritual acupoints of Mount Buzhou's ancestral vein. It could be considered one of the most supreme blessed lands in the Primordial World, and there were likely few grotto-heavens in the Primordial World that could compare with it.

"A great opportunity!" Yuan Yan rejoiced inwardly.

Although there was no strict hierarchy between grotto-heavens and blessed lands, Yuan Yan could tell from the mysterious Dao rhythm emanating from this grotto-heaven that it was no ordinary place. The innate spirit treasure or innate spirit root being nurtured within would not be ordinary either. It was very likely a supreme-grade innate spirit treasure or a supreme-grade innate spirit root.

The mysterious Dao rhythm it emitted far surpassed that of the blessed land that had nurtured the Yinyang Mirror. Naturally, the innate spirit treasure or innate spirit root nurtured within should far surpass the Yinyang Mirror as well.

The Yinyang Mirror was a high-grade innate spirit treasure with thirty-six innate divine restrictions. Other than a supreme-grade innate spirit treasure or supreme-grade innate spirit root, nothing else could surpass it.

Moreover, this grotto-heaven was of no low grade, so it was naturally qualified to become his Daoist abode.

As for his original place of birth?

Although it was also an excellent place for a Daoist abode and qualified to become one, and although he had made arrangements so that no one could easily intrude and seize it, what kind of place was Mount Buzhou? It would be the core of the future Calamity of Witches and Demons. The Witch Clan would even occupy Mount Buzhou, and after the Calamity of Witches and Demons, Gonggong would directly smash Mount Buzhou apart.

If he established his Daoist abode on Mount Buzhou in the future, trouble would surely be endless.

Making this grotto-heaven his Daoist abode would be different. Although its entrance was on Mount Buzhou, its true body was not. It was actually located in the boundless void. Even if Mount Buzhou collapsed, it would not be implicated.

Once his cultivation realm became high enough, he could even completely alter this grotto-heaven's entrance within the Primordial World.

The unseen pull and sense of opportunity grew ever stronger. Yuan Yan did not hesitate. He evolved a formation at the entrance to conceal both the entrance and the Great Dao fluctuations it emitted, then stepped into the realm gate.
