Some of the rare and precious Heavenly Materials and Earthly Treasures cannot be bought with wealth.

For Martial Arts Strongmen who have reached a certain level, gold and silver are mere numbers and offer no support to their personal strength.

Thus, for these Martial Arts Strongmen, gold and silver are no different from ordinary stones.

The only thing useful is what could help his descendants or family.

But some Martial Arts Strongmen do not even care about that.

"This journey was truly worth it!!" He withdrew his gaze from the internal space of the Jiezhi Leaf, sighing in his heart.

Originally, he came to this Grotto Heaven just to give it a try.

Unexpectedly, relying on his mastery and insight into space achieved through the perfection of the Taixu Yin Yang Sword, he was able to actively enter an unopened Pocket World.

Moreover, the Grotto Heaven on Yang Lake, attributed to the Shangyang Immortal Sect, contained the Pure Yin and Yang Qi he needed to achieve the Yin Yang Dao Embryo, just as he expected.

This allowed him to complete the Nine Mysteries Transformation of the Yin Yang Dao Embryo, achieving complete success.

Additionally, it brought him such abundant rewards, indeed a multiple gain.

Then, he soared into the sky and reached the edge of the island in just a moment, heading straight into the vast ocean.

He rushed towards another island that he had locked onto with his sight.

This island was larger than the one he had just plundered and even larger than the first island.

On the island, colorful rays shone, with treasures clearly present.

Just as he stepped off the island and rushed into the sea,

the space above the sea surface suddenly rippled, and a gentle yet vast and majestic will swept over his Spirit Platform like a breeze.

"Disciple of the true tradition, the Yin and Yang of this Grotto Heaven flow with their own balance, and all things follow their rules. Since you have obtained what you needed, you should leave and not disturb the natural order here further."

The voice was indifferent and calm, yet it echoed within Jiang Ning’s Heart Spirit like a heavenly decree, carrying the natural majesty and vastness of the will of the Grotto Heaven.

Jiang Ning paused, suspended between the sea and sky, with a slight frown.

He looked up at the dome of the sky, though he saw no form or shadow, he could clearly sense the watchful gaze of that vast will.

It didn’t show any anger, more of a reminder or a warning based on rules.

"I understand," Jiang Ning said aloud, his voice reverberating over the sea, respectful in attitude.

He had no intention of angering the will of this world, having some expectations in his heart, and his actions had been probing the permitted boundaries.

Now that he had received a clear indication, he should stop appropriately.

The will didn’t say more, receding like a tide, the sky returned to clarity, only the ten Great Suns remained in the sky.

Jiang Ning glanced at the distant islands he had yet to explore, a trace of regret in his eyes, but quickly he came to terms with it.

The gains from this journey had already far exceeded expectations.

Not only had he successfully forged the Yin Yang Dao Embryo, taking a crucial step toward achieving the Primordial Spirit.

He also scavenged a large amount of Heavenly Materials and Earthly Treasures imbued with Great Sun Essence Qi from this Cave Heaven Blessed Land.

These resources were enough to significantly advance his Inner Elixir Cultivation Skill, providing a substantial accumulation of Source Points for the breakthrough of other cultivation techniques.

"Since the will of the Grotto Heaven has been expressed, the most urgent matter now is to return to the Royal Capital, to wait for the Dao Embryo to mature and the Primordial Spirit to emerge," he concluded in his mind.

Then he turned, transforming into a swift streak of light, flying towards the spatial node he sensed upon his arrival.

There, a crack existed connecting the Grotto Heaven to the outside Yang Lake.

Moments later, he reached a certain height in the sky.

The scene before him seemed no different from anywhere else, but with his now heightened perception due to the initial completion of the Dao Embryo, a subtle golden spatial crack rippled like a water pattern in the void, faintly revealing the mist and sky light of the outside Yang Lake.

"Open!"

He pointed like a sword and made a slight motion.

The understanding of the Dao of Space had become instinctual since the perfection of the Taixu Yin Yang Sword, and now, with the sublimation of the Divine Soul, he could control it with subtlety.

He saw the golden crack respond by expanding into a portal large enough for someone to pass through, revealing the clear scenery outside.

Beyond lay the vast expanse of Yang Lake and the silhouettes of distant rolling mountains.

He stepped out, his figure entering the crack.

In the next moment, light and shadow shifted, the space transitioned.

A familiar cool lake breeze greeted him, below his feet was the rippling lake water.

Jiang Ning stood above Yang Lake, looking back, the crack closed in an instant, eventually disappearing completely into the void, leaving no trace.

It was now afternoon in the outside world, the sun leaning westward, the lake surface shimmering with golden light.

In stark contrast to the blazing scene within the ten-day-lit Grotto Heaven, it appeared peaceful and serene.

Jiang Ning took a deep breath, feeling the significantly thinner Spiritual Energy between heaven and earth.

The Yin Yang Dao Embryo within his Spirit Platform rotated slowly, with the Yin Yang Mysterious Light converging, simultaneously absorbing and emitting the energy flowing from the outside world, continually nourishing itself.

"Time to go back." He whispered in his heart, discerning his direction.

The Royal Capital was not close, but at his current speed, he could reach it within two hours if he traveled at full speed.

The next moment.

He didn’t pause, his figure flickered and disappeared above Yang Lake.

Hidden from the outside, he traversed through high mountains and forests like a line, heading straight toward Shangjing County where the Royal Capital was located.

In the process, whatever lay ahead posed no barrier to him, having no impact on him whatsoever.

His progress caused no disturbance.

As he moved forward, his thoughts surged within.

This journey to the Yang Lake Grotto Heaven yielded far more than expected.

The Yin Yang Dao Embryo was complete, just waiting for the Primordial Spirit to emerge, allowing him to truly establish himself as an Immortal.

The Heavenly Materials and Earthly Treasures scavenged were enough to advance the Inner Elixir Cultivation significantly, accumulating substantial Source Points.

Meanwhile, the final reminder from the will of the Grotto Heaven reassured him that even though this world recognized him as a true disciple of Shangyang, it also had its own unbreachable rule boundaries.

In the future, I must be more cautious when entering other Cave Heaven Blessed Lands."

"However, the most pressing concern is still the situation in the Royal Capital." His eyes narrowed slightly, his speed increased by three points, a thought crossing his mind: "That gray-robed old man died by my hand. Ji Xuan must have known. With his temperament and skill, second to none in the world, he will never let it rest. The reason he didn’t take action at court was likely because of his self-esteem, or he was planning a greater scheme, or he had concerns about the State Preceptor and the Martial Saint. But now that I have killed his man, it is a complete break in relations. If he takes action personally....."

At this thought, Jiang Ning was startled.

Ji Xuan’s strength was unfathomable; he was already acclaimed as second in the world over a century ago, and after such a long time, his fearsome power could only have increased.

Even if he had formed a Yin Yang Dao Embryo and his Divine Soul had sublimated, against such a formidable adversary, the outcome was still unpredictable.

"I must return quickly to discuss countermeasures with Su Qingying. Meanwhile, I also need to refine all the resources obtained from the Grotto Heaven during this time, any increase in strength is beneficial."

As he moved swiftly, he looked inwardly at his Spirit Platform.

The pigeon egg-sized Dao Embryo of Yin Yang was quietly suspended, enveloped by the slowly circulating Yin Yang Mysterious Light, every rotation absorbing spiritual power within the Spirit Platform, releasing a sliver of more refined Divine Soul Origin.

The Dao Embryo was brimming with life, seemingly nurturing something, and once the time was ripe, it would break out.

"According to the inheritance, the warming of the Dao Embryo could take anywhere from several days to over a month. My Divine Soul was already resilient, and after experiencing the Heavenly Ladder’s tempering, perhaps this time could be shortened." Jiang Ning estimated to himself, "If I can achieve the Primordial Spirit before Ji Xuan makes his move, it would greatly increase my confidence."

Amidst his contemplation, he surpassed countless mountains, and ahead, undulating hills, stretched official roads, and distant townships with curling smoke appeared.

A moment later.

He entered the territory of Shangjing County.

Moments later.

The undulating walls of the Royal Capital, like a black python, emerged in his sight.

"I’m back again!"

"I wonder what has happened within the Royal Capital during these days while the Armored King ruled the court."

He mused silently in his heart.

Then, in an instant, he passed through the grand formation covering the sky above the Royal Capital without causing any ripple.

With his current means, the great formation shrouding the Royal Capital day and night could not detect him at all.

He could easily do what many strongmen could not, entering and exiting the Royal Capital freely without being noticed.
