Chapter 1644: Chapter 78: The Transformation of the Nine Mysterious, Achievement!

Yang Lake Grotto Heaven.

A figure swept across the sea surface, stirring a long wave of air.

This figure was Jiang Ning.

In this Grotto Heaven, he didn’t need any restraint and could fly freely, traversing across.

On the sea surface, looking at the enormous island in the distance, Jiang Ning’s thoughts surged: "Once I achieve the Primordial Spirit, I will truly enter the realm of Immortals, and possess the highest level of Immortal Dao Foundation. At that time, the Divine Soul will undergo a qualitative transformation. With the power of the Primordial Spirit, I will be able to create my own world, mastering incredible Divine Skills and methods. These will significantly enhance my understanding of world rules, Martial Arts Skills, and cognitive ability, propelling me to a whole new level. Facing Ji Xuan, I will have a more solid confidence."

"However, casting the Dao Embryo and transforming the Primordial Spirit is not something that happens overnight; it requires time to hone. I hope during this period, things at the Royal Capital remain stable."

"But with Su Qingying there, it should be all right."

Various thoughts flashed through his mind. 𝗳𝐫𝚎𝗲𝚠𝚎𝗯𝕟𝐨𝘃𝚎𝗹.𝗰𝗼𝗺

Moments later.

He descended from high altitude, landing on the lush island.

He found a rock wall covered with vines, raised his hand, and dug out a stone cave in the middle of the wall.

He dove into the cave, and as the vines fell, he instantly melded completely into the island, showing no sign of anomaly.

Currently.

Jiang Ning appeared in a stone cave about one zhang wide and two zhang high.

With the thick vines covering the outside, the cave instantly turned pitch black.

Even though he could already perceive night as bright as day.

His long-standing habit as a human made him feel slightly uncomfortable.

He knew this was instinctual human senses, favoring light and disliking darkness.

He frowned, looking upward at the cave’s ceiling.

With a flick of his fingers next.

Swoosh—

Swoosh—

Swoosh—

Energetic forces pierced through the air.

In just an instant, five chaotic, overlapping holes appeared in the cave’s ceiling.

The holes were finger-sized, and five bright beams of light shone through them, instantly illuminating a large part of the cave.

"That’s better!" he nodded slightly in satisfaction.

Then sat cross-legged in the cave, placing the purple bottle containing Pure Yin Qi and the golden bottle containing Pure Yang Qi in front.

After a long time, his mind returned to tranquility, free from the growth of distracting thoughts.

This step was to forge the Yin Yang Dao Embryo, achieving the Nine Profound Yin Yang Immortal.

Such a crucial step demanded his utmost caution.

Once successful, with the accomplishment of the Primordial Spirit, he could rival those ancient monsters in the Cave Heaven Blessed Land.

Like Qingyuan Taoist, like Xia Xuanyan, and others.

These are monsters who have lived for over a thousand years.

After adjustments, his mind sank deep into the Spirit Platform.

The Yin Yang Dao Embryo’s inherited spell flowed like a spring in his heart, each word like a precious bead, echoing within.

Each word contained the ultimate truths of Yin Yang rotation and the cycle of creation and destruction.

Even a simple review stirred a faint ripple within his heart.

Sigh—

He slowly exhaled again, adjusting his breath, and brought his state to Empty Brightness.

Then, his hands gently raised, and simultaneously opened the jade bottle containing the ultra-pure Yin Yang Qi in front of him.

"Buzz—"

Upon opening the bottle, a wave of extreme cold and a wave of extreme heat spread out, dividing the cave clearly.

The left side was suffused with purple light, and the moisture in the air instantly condensed into ice crystals, adhering to the stone wall.

The right side flowed with golden brilliance, warping the air slightly with heat.

The two purest energies, despite their extreme attributes, didn’t clash but began to spin, compelled by Jiang Ning’s Spirit Platform sensation, slowly approaching each other.

"Yin and Yang not separated, chaos like an egg. Today, I gather the two energies, forging my Dao Foundation."

Jiang Ning silently recited the spell in his heart, with Divine Sense in the Spirit Platform like an invisible hand carefully extending, capturing a wisp of Pure Yin Purple Qi and a wisp of Pure Yang Golden Qi.

The two wisps, as thin as hair, slightly trembled like having spirituality upon leaving the bottle, causing surrounding light to alternate between brightness and darkness.

He dared not slack off, using his comprehension and understanding of the Yin Yang Dao Principle after the Perfection of Taixu Yin Yang Sword, guiding the two wisps of energy to merge in the void three feet before him.

At the start, Yin and Yang repelled each other, causing ripples in space.

Jiang Ning held his breath, using Divine Sense as the furnace, will as the fire, slowly harmonizing according to the "Yin Yang Intertwining" Secret Technique recorded in the Yin Yang Dao Embryo.

In his heart, he envisioned the rotation of Tai Chi Yin Yang fish, where Yin contained Yang and Yang held Yin, chasing one another as the foundation of each.

Time flowed silently. In the cave, only the purple-gold halo slowly spun, collapsed, and condensed.

As time passed, sweat seeped from Jiang Ning’s forehead, with Divine Sense depleting greatly.

When his vitality slipped to a certain level, vigor erupted within his body like a deadwood meeting spring, akin to plants growing.

The Essence Qi from the Silver Spear Fish he consumed and refined within cells ignited like firewood, nurturing his body’s status recovery.

"As expected, without a mentor by my side, there are many pitfalls!" At this moment, a feeling-laden stray thought swiftly flashed through his mind, then was instantly severed.

The immense vitality explosion instantly returned him to the Peak.

At dusk, day and night alternated.

Outside the cave, the sky seemed to be infused with ink, with the night enveloping thickly like ink.

Darkness crept inside the cave, through vine gaps, flooding the zhang-wide cave.

But inside the cave, the spinning purple-gold halo repelled the incoming darkness once again.

A cycle repeated.

...

A night passed.
