The break of dawn appeared, and white light filtered through five finger-sized holes above the stone cave, illuminating it.

At this moment, the purple-gold halo, originally about a foot in size, had been refined to the size of a fist, resembling a smooth and round alchemical pill. The surface shimmered with streaming lights; purple and gold no longer clashed distinctly but merged like water and milk, forming a profound and harmonious mystical pattern, slowly circulating.

In the core, a hint of chaos quietly sprouted, as if containing a microcosmic embryo of the world.

"With the initial condensation of the Dao embryo, it must enter the Spirit Platform to be nurtured by the Divine Soul, undergoing the transformations of the Nine Profound Changes."

With a thought from Jiang Ning, the purple-gold Dao embryo transformed into a stream of light, directly entering his forehead and sinking into the depths of the sea of consciousness within the Spirit Platform.

Boom!

The moment the Dao embryo entered his body, Jiang Ning’s entire body trembled violently.

In the Spirit Platform, it was as if a sun and a cold moon had been cast.

The sensations of extreme heat and extreme cold acted not on the physical body but directly on the Divine Soul Origin.

On one side was the burning that could incinerate all things, while on the other side was a freezing cold that froze the soul. These two extreme sensations erupted simultaneously, almost tearing apart his consciousness.

He gritted his teeth, resolutely holding onto a sliver of clarity in his Heart Spirit, and operated the techniques within the Yin Yang Dao Embryo.

At this moment, the golden Divine Soul in the Spirit Platform began to move towards the purple-gold Dao embryo.

With each step, the golden Divine Soul shrank a little.

The closer it got, the smaller the golden Divine Soul became.

However, as the golden Divine Soul approached, the freezing cold and searing heat grew more terrifying, seeming to freeze his Divine Soul solid or completely smelt it.

"If I hadn’t achieved the Yang God, I would have already been ignited by this purple-gold mingling Dao embryo!" he silently mused in his heart.

Having been refined by the pressure on the celestial ladder, the convergence of cold and heat could no longer substantially affect his Divine Soul.

By the time he reached the purple Dao embryo, the golden Divine Soul had shrunk to a size slightly smaller than a fist, only about an inch in height.

Then, in front of the merging purple-gold Dao embryo, the golden Divine Soul leaped in and instantly entered.

The entrance of the Divine Soul into the embryo felt like returning to the womb or throwing oneself into a furnace.

Inside the Dao embryo was not a solid body, but a scene of chaos yet to be born. The purple-gold qi transformed into innumerable intricate runic chains, weaving into a net to enwrap the Divine Soul.

Jiang Ning felt his Divine Soul consciousness undergoing a strange disassembly and reformation.

Past understandings, memories, and even his insight and comprehension of Martial Arts became blurred under the washing of the Yin and Yang Qi.

Yet under the nourishment of that chaostic intent, they recondensed, becoming purer, more refined, and transparent.

This was the first transformation of the Nine Profound Changes.

Using Pure Yin Qi to wash away the impurities of the Divine Soul, and Pure Yang fire to refine the ethereal nature of the Divine Soul, Yin and Yang working together to allow the Divine Soul’s essence to undergo its first transcendence.

Pain and enlightenment intertwined at this moment.

Jiang Ning’s Divine Soul within the Dao embryo felt at times frozen, with thoughts stagnant.

At times it felt scorched, with intentions boiling.

Time passed without notice, and the first transformation was completed.

The Divine Soul had noticeably shrunk in size but became more solid, emitting a faint jade-like luster, with a clarity of connection to the Yin and Yang Dao multiplying severalfold.

Afterward, he willed a slight thought.

Placed before him, in the jade bottle containing the Yin Yang qi, suddenly a purple and a golden light rose and converged towards his brow.

In just an instant.

The dual purple-golden lights disappeared into his brow and manifested within the Spirit Platform.

As the pure Yin and Yang Qi appeared in the Spirit Platform.

The Spirit Platform trembled slightly.

The dual pure Yin and Yang Qi traversed across the Spirit Platform and entered the purple Dao embryo.

Immediately following, the second transformation began.

The infusion of the pure purple-golden qi made the runic chains in the Dao embryo contract, akin to forging divine iron, subjecting the Divine Soul to relentless refinement.

Each strike was accompanied by immense pain.

Yet it also imprinted more Yin Yang laws deep into the Divine Soul.

Jiang Ning’s Divine Soul adapted in the tempering, absorbing the traits of the Yin Yang Qi, and gradually achieving stronger resonance with the external Yin Yang Qi.

The third transformation "Transformation of Void and Mystery" ... the fourth transformation "Nurturing of Spirit" ...

Through the Nine Profound Changes, each transformation more difficult than the last, the test on the Divine Soul increased exponentially.

Each required Jiang Ning to persist with immense endurance and a profound foundation of the strength of the Divine Soul.

Coupled with deep insight into the Yin Yang Dao to support.

Active comprehension, containment, and acceptance, embracing the baptism of Yin Yang creations, were the keys to successful cultivation.

...

Outside the stone cave, day and night alternated.

Inside the cave, Jiang Ning’s body remained like a rock, his aura sometimes erupted like a volcano, sometimes sunk into stillness like a cold abyss.

On the surface of his body, faint gold and deep purple patterns alternated.

Above his head, a faint shadow of a Tai Chi Diagram formed by Yin Yang Qi slowly rotated, echoing with the transformation within the Spirit Platform’s Dao embryo.

At this moment, the ninth transformation "Return to Truth" was also thoroughly accomplished.

The final two pure Yin Yang Qi also merged into his Spirit Platform.

The Dao embryo in the Spirit Platform was no longer the size of a fist, but shrunk to the size of a pigeon’s egg.

The purple and gold qi fused into chaotic mysterious light, and Jiang Ning’s Divine Soul became one with the Dao embryo.

The Dao embryo resembled a turbid egg, wrapped in endlessly circulating Yin Yang mysterious light on the outside, with an abundant and majestic genesis life force inside, as if a miniature world embryo was quietly nurtured in the depths of the Spirit Platform.

Jiang Ning’s mind became clear, sensing that the ninth transformation had reached Perfection.

This signified that the Yin Yang Dao embryo was complete, requiring only continued nurturing until natural maturity, allowing the Primordial Spirit to break through, fully achieving the foundation of the Nine Profound Yin Yang Immortal Dao.

He suppressed the excitement in his heart, following the technique to sink the last wisp of his mind into the Dao embryo, guiding the chaotic mysterious light to slowly converge, making the Dao embryo stabilize completely at the center of the Spirit Platform.

In the stone cave, the visions around Jiang Ning gradually faded, the intertwined purple-gold patterns on his body disappeared, and the Tai Chi shadow above his head also dissipated into invisibility.

Yet his aura became ever deeper and unfathomable, resonating with the Yin Yang rhythms of the Pocket World.

Even with eyes closed and meditating, he could sense the Pure Yang Qi radiated by the Great Sun over Yang Lake and the Pure Yin force flowing in the depths of the Yin River in the sea.

"The Dao embryo is formed, the gestation of the Primordial Spirit is merely a matter of time." Jiang Ning realized in his heart.

According to the inheritance description, thereafter, it required the nurturing of the Dao embryo day and night, for a few days to a month or more.

Once the life force within the Dao embryo was accumulated to the brim, it would naturally sense the Heaven and Earth Laws, causing the Mystic Patterns to blossom.

Then, the Natal Primordial Spirit would break out of the embryo, stepping into the Immortal realm, titled "Nine Profound Yin Yang Immortal."

He slowly opened his eyes, chaos seemed to flash and vanish within his pupils. Though

the Primordial Spirit had not fully achieved, the Spirit Platform had become incomparably clear and broad because of the presence of the Dao embryo, elevating his insight into Yin Yang, space-time, and even the life and death of all things to a brand new level.

Even the efficiency of condensing the Divine Power within his body also subtly accelerated due to the elevation of the Divine Soul.

At this moment, with a thought, this realm could no longer confine the expansion of his intentions, the entire island was unexpectedly enveloped by his heart and mind.

The full view of the island became vividly clear in his mind.

Every flower, every grass, every tree, and every stone, everything was crystal clear.

He saw all kinds of Heavenly Materials and Earthly Treasures, witnessing the gathering of the Great Sun Essence Qi.

Simultaneously, the seawater could not obstruct his mind, the swimming Silver Spear Fish in the sea, and even the profound purple Yin River, all vividly reflected in his new consciousness.

He looked up at the sky above.

In the Mingming, he sensed the will of the Grotto Heaven above the zenith.

It was the will birthed by this realm.

It was also the master of this realm.

"Just by achieving the basic cultivation, there are such transformations. I wonder what divine skills will manifest upon breaking the embryo and fully achieving the Nine Profound Yin Yang Immortal!"

His heart suddenly filled with anticipation.

Then, he looked towards the direction outside the stone cave, his heart burning with fervor.

The entire view of the island, every plant and tree, reflected in his mind. 𝕗𝐫𝐞𝕖𝕨𝐞𝗯𝚗𝕠𝘃𝐞𝚕.𝐜𝗼𝚖

This meant that all those Heavenly Materials and Earthly Treasures belonged to him, he could simply walk over and take them without competition.

Just this alone filled his heart with immense excitement.

It was a substantial income of Source Points.

Moreover, the Heavenly Materials and Earthly Treasures of this place were bathed in the sun daily, accumulated over the years, already amassing a huge amount of Great Sun Essence Qi.

If he refined this Great Sun Essence Qi, it could temper his viscera, greatly benefiting his Inner Elixir Cultivation Skill, and significantly shortening his accumulation process.
