Wu Yuan, who had been sitting in lotus position in the void, opened his eyes. In a single decisive step, he found himself before the temple.

The temple was an imposing structure, towering ten li high and stretching a hundred li wide, seemingly cast entirely from bronze. It exuded an aura that was both ancient and otherworldly.

Curiosity piqued, Wu Yuan gave a mental command, attempting to store this temple. To ordinary mortals, its grandeur was overwhelming, but Wu Yuan had seen all sorts of wondrous structures and artifacts in his lifetime too.

𝒇𝙧𝙚𝓮𝙬𝙚𝓫𝒏𝓸𝓿𝓮𝒍.𝓬𝙤𝓶

Yet, as made the attempt, an indomitable force pressed upon him, nearly buckling his knees.

How strong!

His pupils constricted, acknowledging that he could not keep this temple for himself. It was no mere mortal structure; it seemed intertwined with the very fabric of the Divine Domain World, as though a sort of manifestation of the world.

This Divine Domain World, this temple, and the entire Megaverse Crossroads—could they truly be natural formations?

Wu Yuan mused, wondering if some invisible hand orchestrated their creation, laying down their rules.

However, Wu Yuan didn't dwell long on these thoughts. The Megaverse Crossroads remained an enigma. Even supreme beings couldn’t interfere with it, rendering his concerns moot.

Let’s see what’s inside.

He decided.

Wu Yuan’s qi refiner self began making his way up the temple’s steps. Each step brought an onslaught of immense pressure, yet he endured. For ordinary High Immortals or High Deities, this pressure would have crushed them to death, but Wu Yuan held firm.

At the entrance stood a series of imposing pillars, austere in their lack of carvings or embellishments.

Wu Yuan reached out, his touch setting the heavy doors into motion. They opened with a thunderous boom, releasing a cascade of misty light that shrouded him entirely.

Hmm?

Wu Yuan's eyes narrowed as an irresistible force enveloped him, and he disappeared from the temple's entrance.

Boom!

The temple doors slammed shut, and a tremor coursed through the structure. A flash of misty light enveloped the temple once more, and then it vanished completely.

Silence reclaimed the area, leaving no trace of the temple's existence, as though it had never been there at all.

"Has it vanished?"

"Where does this temple lead to?”

"It must be a great opportunity.”

"But it seems... only one person can enter." The many prodigies lurking in the distance observed with astonishment and a twinge of disappointment. They all sensed a profound opportunity slipping through their fingers.

The so-called providence did not offer direct assistance. Instead, it aided those who encountered it. When a great opportunity appeared, only those who were present had the chance to seize it. That was the function of providence.

Prodigies like Jin Tong, Wu Yuan, and others managed to reach the temple before it fully manifested—this was their providence, indicating that they were fated with it.

Without this providence, strength alone would be meaningless. Lacking the ability to arrive on time meant they could not hope to enter the temple.

However, when providence smiles upon you, it must be met with strength to grasp it. Evidently, Wu Yuan was the one who possessed both the providence and the power to claim it.

Shortly thereafter, news of Ming Jian entering a mysterious temple, followed by its sudden disappearance, spread.

Yet, the news drew little attention. After all, among the countless prodigies within fifty-five Divine Domain Worlds, some had already encountered similar opportunities, and over time, the frequency of such opportunities was bound to increase.

The situation in the Megaverse Crossroads was closely monitored by supreme beings, and with just cause.

...

This was a mysterious place enveloped by the void on all sides.

Wu Yuan’s qi refiner self and mana body stood at its heart.

What is this place?

He wondered, cautiously probing his surroundings. Moments ago, a shapeless force had enveloped him, whisking him away to this location.

Moreover, upon his arrival, Wu Yuan noticed that his Soul Will felt trapped within his body, and his mana, although present, was subtly restrained and difficult to wield. However, this was merely a secondary concern.

More pressing was the realization that his qi refiner self's perception of various Daos’ essences was now obscured, as though veiled. He could not sense the essences of Great Daos at all.

The environment here was unquestionably unique.

Abruptly, a low hum filled the air. Countless streams of purple light materialized from the void, coalescing into a jade stone resembling an immortal slip that hovered before Wu Yuan.

Simultaneously, an inexplicable message unfurled directly into his mind.

So, that's how it is.

Wu Yuan murmured, a flicker of joy lighting his eyes as understanding dawned upon him. His gaze swept across the void.

So, this is actually the Primordial Doctrine Temple.

The message was complex, but could be summarized in two points.

First, the jade stone held the first three chapters of the Primordial Doctrine. The entire Primordial Doctrine spanned nine chapters in total.

Secondly, this place was the Primordial Doctrine Temple, which had an environment that enhanced the comprehension of this teaching.

Wu Yuan had the opportunity to cultivate here for as long as a century.

That said, the hundred-year period wasn't absolutely binding. Wu Yuan had the freedom to leave whenever he chose.

Heh, why would I want to leave early?

He mused to himself, a subtle grin appearing on the face of his qi-refining self.

Who would have thought that I’d already gain access to the Primordial Doctrine.

There were three distinct paths to enter the Heavenly Domain stage: killing a significant number of powerhouses, attaining Sovereign-level Dao comprehension, or comprehending the ‘Primordial Doctrine'.

The various Saintdoms were all curious about this teaching, and were in the midst of investigating it. Yet, even the Eldritch Court and Immortal Court had not yet discovered the means to acquire them. Meanwhile, Wu Yuan had managed to do so just like that.

Let's take a look.

Wu Yuan decided, reaching out to touch the purple jade stone. He braced himself, channeling his Soul Will to withstand the immense pressure, just enough to access the immortal slip.

Boom!

An overwhelming wave of information crashed into his mind, leaving even his powerful Yuan Soul momentarily stunned.

A moment later, he exhaled deeply, his qi refiner self waking. Then, Wu Yuan closed his eyes again, focusing inwards to sense and unravel the complexities of the 'Primordial Doctrine' he had just acquired. The depth and intricacy of the teaching was astonishing.

A full day slipped by before Wu Yuan's qi refiner self fully returned to awareness, his eyes wide with astonishment and disbelief.

How can such a miraculous teaching exist in this world?

He muttered.

Primordial Doctrine? It encompasses the fundamental nature of all origins?

His brief contemplation of this chapter had profoundly shaken him. This was not just another Dao teaching or secret art. It took an entirely different approach, employing pure matter to deduce and construct the ultimate profundities.

He mused silently.

Traditional cultivation methods, whether they are supreme burst arts like 'Creation Saint Prohibition,' or combat secret techniques such as 'Nine Swords of Spacetime' and 'Will of Life and Death,' all trace their roots back to the 'Dao'.

The Dao was the bedrock of all existence! It governed the natural order of heaven and earth, empowering the transformation of all objects, living beings, and matter itself through its operation and power.

For the innumerable cultivators—be they qi refiners, body refiners, or the Abyssal devil race with their myriad skills and teachings—the foundation of their abilities was rooted in Dao comprehension. Once one's understanding of the Dao reached a certain depth, it naturally connected to all methods, enhancing other aspects along the way.

Yet, the 'Primordial Doctrine' that Wu Yuan discovered today stood apart—it proposed a cultivation path focused on the study of matter.

"The Dao exists within all things, and comes to life through their workings.” This was the core tenet of this teaching.

It asserted that Dao and Laws came into being because of the existence of all things. If all matter were to vanish, returning to nothingness, all Dao and Laws would cease to be.

Matter, Laws.

Wu Yuan deliberated.

Which came from which?

He felt this inquiry probed into the fundamental nature of the endless megaverse, the entire space-time continuum, indeed the origin of all things. It was already beyond the scope of what someone at his level could deduce and comprehend.

Moreover, even Sovereigns and Overlords would likely find such investigations daunting. According to Wu Yuan's speculations, perhaps only supreme beings possessed the qualifications to explore the origins of all things.

But who devised this 'Primordial Doctrine'?

Wu Yuan's curiosity intensified.

Who possessed the insight to develop such an extraordinary teaching? It transcended every teaching Wu Yuan had previously encountered, appearing to belong to an entirely different cultivation system. It was unlike anything he had known.

The Megaverse Crossroads encouraged the countless prodigies of the current era to pursue this teaching—what was the underlying purpose?

Wu Yuan inhaled deeply, reflecting on his situation.

No point overthinking it.

He thought.

Let the lofty figures tackle the grand challenges. My focus should be on cultivating and understanding the 'Primordial Doctrine' first.

He had only acquired the first three chapters of the doctrine: the Spacetime Chapter, the Life Chapter, and the Myriad Things Chapter.

The Spacetime Chapter mirrored aspects of the Spacetime Dao, yet had fundamental distinctions—it didn't explain the profundities of the Spacetime Dao. Instead, it detailed the physical construction of time and space.

In the 'Primordial Doctrine', time and space weren't just abstract ideas; they existed as tangible matter.

Even the spirit, Destiny Voidscape, and karma were considered actual matter. What many referred to as the void or virtual aspect of heaven and earth was, fundamentally, all matter.

Yet, many types of matter were exceedingly rare, concealed deep within heaven and earth, undetectable and undiscoverable by ordinary beings.

All Daos and all Laws are not mere intangible concepts but originate from reality, from matter.

Wu Yuan pondered.

This revelation in the 'Primordial Doctrine' shook the foundation of Wu Yuan's nearly twenty thousand years of cultivation. Yet, it also filled him with eager anticipation.

Take it slow.

He reminded himself.

First, thoroughly grasp the Three Thousand Foundation Diagrams of the Spacetime Chapter.

With a focused mind, Wu Yuan began to contemplate.

Though time was short, he had a glimpse of why the Primordial Doctrine Temple was invaluable for cultivating this teaching.

Outside its walls, powerful cultivators were constantly influenced by numerous Dao essences. This exposure, even as they cultivated the 'Primordial Doctrine', led to a biased understanding of all things and matter.

However, within the confines of the Primordial Doctrine Temple, this influence was minimized. This created an ideal environment for deeper comprehension of the 'Primordial Doctrine'.

The years slipped by. Wu Yuan's qi refiner self and mana body remained within the Primordial Doctrine Temple, cultivating in silence.

The Megaverse Crossroads was alive with fierce battles as various prodigies clashed incessantly. Meanwhile, Wu Yuan's ether body continued his ventures in Divine Domain World 7, gaining fame and recognition.
