Chapter 581

Within the Yin Primordial Spirit’s internal universe

Yin energy filled the cosmos. This was a universe rooted in the principles of Yin—a domain of cold and darkness.

Normally, once a cultivator reached the Path-Clearing stage, they would have already birthed an internal universe.

Its rules would be fully developed and balanced, standing independent from the real universe.

But in truth, every internal universe was shaped by its creator’s insights and path.

Each cultivator’s understanding of the laws varied, and those differences influenced their internal universes.

Such was the case with the Yin Primordial Spirit's universe—

Clearly aligned with the Tao of Yin.

The same was true for the Yang Primordial Spirit, rooted in Yang.

As for the true body? It fused both Yin and Yang into Tai Chi, birthing all things, with no extreme leaning.

The internal universe of the true body was most akin to the real universe—its myriad laws held in perfect balance.

And now, in this endlessly cold and shadowed Yin universe, a spark of flame erupted, blazing fiercely. Wherever its light fell, it claimed dominion.

Light and heat radiated outward, dispelling the cold.

The entire Yin universe began undergoing a mysterious transformation.

“This change…”

“A balance is forming between the Yin universe’s origin and the Sunborn Core?”

Lin Yuan’s expression shifted slightly.

Yin and Yang could easily reach equilibrium—they were the two foundations of his Tao of Tai Chi.

But Yin and Sunborn?

Sunborn and Yang might both be “yang”-typed energies, but they represented fundamentally different Daos.

Yet here in the Yin universe, the omnipresent Yin origin and the Sunborn Core began transforming into one another, forming a relatively stable cycle.

This cycle was triggering a fundamental transformation in the structure of the Yin universe—its stability and origin density soaring dramatically.

“The Sunborn Core, born of my divine ability

Sunborn Genesis

, belongs to me—so the world it creates is also mine.”

“But the Yin universe was also birthed by me. In essence, it’s my domain too.”

“That’s why the Sunborn Core is converting the Yin universe so smoothly—there’s almost no rejection.”

Lin Yuan watched as the radiance of the Sunborn Core spread ever farther through the Yin universe, deep in thought.

Sunborn Genesis

was a divine ability with an immense energy cost—Lin Yuan had known this the moment he awakened it.

Even exhausting all his origin power, he wouldn’t be able to maintain it for long.

Why? Because its nature lay in forcibly reclassifying the surrounding world as Lin Yuan’s own domain.

The real cost stemmed from the “resistance” and “rejection” that occurred.

But within the Yin universe, the surrounding world was already his. The expansion of the Sunborn Core encountered almost no opposition.

Lin Yuan could even sense that—if he wished—the Sunborn Core could persist indefinitely here.

“It’s merging. The Sunborn Core is merging with the Yin universe.”

Lin Yuan observed carefully and detected this very trend.

The deeper the fusion, the more complete the cycle between the Sunborn Core and the Yin universe—and the more the entire cosmos benefited.

“This is incredible…”

As the universe’s creator, Lin Yuan clearly perceived the myriad shifts taking place during the fusion of Sunborn and Yin.

“The Sunborn Core is able to merge with the Yin universe because this universe also cultivated

Infinite Void

—that’s what allows it to contain the Sunborn Core.”

He thought to himself.

Originally, he had tested the Sunborn Core in an avatar’s internal universe.

As expected, the universe collapsed instantly—it couldn’t handle the Core’s power.

The Sunborn Core was born from the divine ability

Sunborn Genesis

, itself derived from the abilities of the Liyang Ancestor in the Source World.

Only a technique crafted by another thirteenth-rank being—

Infinite Void

—could meet the threshold to contain it.

It was like trying to contain an iron needle with a block of tofu: the tofu would be pierced through.

But with an iron box?

No problem.

The Yin universe, having cultivated

Infinite Void

, was that iron box.

“Hm?”

While monitoring the Yin universe’s transformation and maintaining the Sunborn Core—

Suddenly, the blazing Core’s integration faltered, and the balance broke.

In an instant, the Yin universe began to collapse.

“Fusion failed?”

Lin Yuan didn’t find it surprising.

Even the inherently paired Yin and Yang energies had occasionally failed to remain balanced during early fusion attempts—leading to mutual collapse.

Let alone Yin and Sunborn?

“In truth, this isn’t a fusion—it’s a devouring. The Yin origin is slowly consuming the Sunborn Core.”

Lin Yuan acted at once, forming a new Yin Primordial Spirit.

Unlike most twelfth-rank cultivators, who would have to invest tremendous energy to create a new avatar—

Lin Yuan’s two Primordial Spirits were easy to remake.

It cost him almost no time.

This was one of the key advantages of the martial path of evolution. The Chaos Void held endless evolutionary branches, each with strengths and weaknesses.

But few paths could match the martial path’s ability to easily generate new Primordial Spirits.

“Continue.”

Lin Yuan once again began cultivating the Sunborn Core within the Yin universe.

He understood clearly—this fusion of Yin and Sunborn was a massive opportunity.

It was the meeting of two thirteenth-rank methods from entirely different dimensional spaces.

If not for Lin Yuan, they would never have had contact—let alone fused.

In the Source World, most cultivators had shallow foundations. Few even understood the concept of an internal universe.

Even those who had something like

Sunborn Genesis

used it only as a powerful combat technique.

As for using such divine abilitys to refine their very foundation?

Impossible.

Even the rare few in the Source World who had developed something resembling an internal universe had merely formed a “space,” not something enhanced by

Infinite Void

. They couldn’t withstand the Sunborn Core.

Which meant Lin Yuan’s current work—fusing two thirteenth-rank dimensional techniques—was producing transformations that even a thirteenth-rank being might never have predicted.

“This time I’ll reduce the Sunborn Core’s radiance.”

Lin Yuan adjusted his energy output. The previous collapse had been caused by excessive radiance disrupting the balance.

He learned from failure—bringing him closer to success.

Days passed.

In the Chaos Void, Lin Yuan’s true body devoted most of its effort to this merging.

As the fusion progressed, the Yin universe’s growth shocked him.

Its size expanded wildly, and its space-time stability soared.

Eventually—

The Sunborn Core and the Yin universe fully merged.

More accurately, the Sunborn Core became part of the Yin universe.

The world birthed by

Sunborn Genesis

had integrated into the Yin cosmos.

In the Star Tear Fragment World

Lin Yuan and the Yin Primordial Spirit sat face to face.

Most of his consciousness was focused on the Yin universe.

“Unbelievable…”

Lin Yuan marveled at the current state of the Yin universe—cold and blazing, coexisting in harmony. At its center, a Sunborn star radiated infinite heat and light.

Compared to a normal star, this Sunborn was vastly more powerful—it had become the universe’s core.

“The Yin universe now spans over ten billion light-years…”

He looked down upon it, eyes full of wonder.

In sheer scale, it now rivaled the true body’s internal universe.

And that was saying something.

Even ignoring external factors like Chaos Void origin infusions or suppression by the Chaos Tree—

The true body’s foundation in Tai Chi, formed by perfectly harmonized Yin and Yang, was far superior.

That internal cosmos was a Tai Chi universe.

“As for power…”

Lin Yuan focused for a moment, then concluded:

It was on par with the true body’s Tai Chi universe.

“All from a single Sunborn Core?”

Even he found it hard to believe. The leap in power was like taking a fresh Dominance-stage cultivator and dragging them straight to the Chaos level.

The abyssal gap between the true body’s cultivated Tai Chi universe and that of a single Primordial Spirit...

Erased just like that?

“If the Yin universe can improve this much… then if the true body’s Tai Chi universe also devours a Sunborn Core…”

Lin Yuan’s heart pounded.

The Tai Chi universe was far more stable than the Yin universe had been.

If even the Yin universe could handle it, then of course the Tai Chi one could.

“Still, I won’t rush into it.”

He remained calm.

He decided to test the Yang Primordial Spirit’s universe next.

He knew from experience that failures could happen—and universe collapse was always a risk.

If his true body’s universe collapsed, the loss would be far greater.

So until he was confident, he wouldn’t try it there.

Buzz!

In the next moment...

The Yang Primordial Spirit appeared.

Lin Yuan’s consciousness entered the Yang universe.

Unlike the Yin universe’s icy stillness, the Yang cosmos was pure blazing power—filled with solar force.

“The Yin universe absorbed the Sunborn Core because of their opposition—but what about the Yang universe?”

After pondering briefly, Lin Yuan summoned a Sunborn Core within it.

Radiance and heat.

Endless light and fire.

As the Yang universe absorbed the Core, Lin Yuan felt the transformations unfold.

Though the Tai Chi path was more balanced than either extreme, that didn’t make the others weak.

On the contrary, extremes could reach unimaginable heights.

Just look at the Liyang Ancestor—his Dao had already reached the thirteenth rank. Many Great Sovereigns and even Heavenly Sovereigns had done similarly with their own Chaos-derived paths.

The Dao has many branches. There is no absolute strong or weak—only different routes to the same truth.

Whoosh…

Sunlight and Sunborn power collided, generating even greater heat.

Lin Yuan made over ten attempts. The Yang Primordial Spirit collapsed over ten times.

But finally—the Sunborn Core fully fused.

“The Yang universe now…”

Lin Yuan steadied himself. Though he was prepared, the universe now radiated a pressure that rivaled his true body’s Tai Chi cosmos.

“Yin and Yang fusion…”

With a thought, he fused the Yin and Yang Primordial Spirits.

Tai Chi was born of Yin and Yang—naturally, it could be divided, and also reunited.

The fusion produced the Tai Chi Primordial Spirit.

Stronger than either alone—not just from combining Yin and Yang, but from merging all their power.

Rumble…

As the two Primordial Spirits fused, so too did their internal universes.

Lin Yuan watched solemnly—if this failed, he’d lose both Primordial Spirits.

Time passed.

Under his gaze—

The Tai Chi Primordial Spirit rapidly formed.

Buzz…

A faint pressure stirred—the formed Tai Chi Primordial Spirit actually exerted pressure on Lin Yuan himself.

“The Tai Chi universe…”

He didn’t hesitate, sending his consciousness into the Tai Chi Primordial Spirit’s cosmos.

The true body’s internal universe was also Tai Chi—but this one was even more powerful.

“Whew…”

He took a deep breath, gazing at the immense Tai Chi universe.

Post-fusion, its diameter approached 90 billion light-years.

An invisible pressure suffused it. At the center burned a great Sunborn star.

As Lin Yuan stared into that star, he almost felt he was looking at the eternal Sunborn of the Source World.

Though it was only a vague resemblance. In power, the Tai Chi universe’s star couldn’t compare.

“This Tai Chi universe…”

Lin Yuan observed it in detail.

“It’s far stronger than the true body’s Tai Chi universe.”

By how much, he wasn’t sure.

Without a reference, what could he do—have the two universes duke it out?

In the true body’s internal universe

Next to the jade gourd, the red-clothed girl was lazily kicking her legs.

“Master probably feels a bit discouraged… only managed ten centimeters on the Immortal Essence Gold.”

She had sensed Lin Yuan’s disappointment.

“I’ll need to cheer him up sometime. That’s Immortal Essence Gold we’re talking about—ten centimeters is amazing already.”

She thought to herself.

Just then, Lin Yuan appeared beside her.

“Master!”

The red-clothed girl leapt up immediately.

“That piece of Immortal Essence Gold—where is it?” Lin Yuan asked with a smile.

“Immortal Essence Gold?” she blinked. “What do you need it for?”

“I want to try again.”

Lin Yuan said casually.

The red-clothed girl blinked again.

Try again?

Did Master think he hadn’t gone all out last time?

“Master, you already did great—ten centimeters on Immortal Essence Gold is incredible.”

She couldn’t help but say.

Enhancing an internal universe isn’t an overnight thing.

She hadn’t sensed that he’d trained much more on

Infinite Void

since then.

So trying again now? Wouldn’t it just be another ten-centimeter mark?
