The Black Bull also recalled its experiences.

It didn’t cultivate the Law; it only cultivated the Physical Body, walking a unique path.

It didn’t need to harmonize with the Great Dao, only to refine its body to the extreme, reaching the level of proving the Dao through strength.

Although that path was different, its danger was not inferior to the ordinary Harmonization.

During body refining, it was often covered in wounds, bloodied, and several times nearly didn’t make it through.

The Old Cyan Dragon was a bit better, not as bumpy as them, but its breakthrough was likewise not easy back then.

Moreover, it followed Gui Xu Taoist for many years, witnessing countless cultivators fail to achieve Harmonization.

Those failures, some would explode and perish on the spot, some would have Divine Thought collapse and turn into idiots, some would be countered by the Great Dao and become ashes.

Each one was a living lesson.

So they knew better than anyone how difficult it was to go from Primordial Spirit to Harmonization.

And Lu Qing?

When he left the Returning Ruins Secret Realm, he was only at the Six Tribulations of Primordial Spirit.

How many years have passed? Not even a hundred years!

In less than a hundred years, to go from Six Tribulations of Primordial Spirit to the Unity Realm Stage, what does this mean?

This cannot simply be described as "talent."

This is simply monstrous!

The Black Bull stared with its round eyes, opened its mouth wanting to say something but found it didn’t know what to say.

Its brain wasn’t very functional to begin with, and it was utterly stuck at this moment.

Ming Feng also lost its usual elegance, its phoenix eyes full of shock, wings unintentionally tightened.

Its noble demeanor was completely gone, leaving only a stunned expression.

The Old Cyan Dragon took a deep breath, suppressing the shock in its heart, and slowly spoke: "Ah Qing, how... how did you do it? In less than a hundred years, from Six Tribulations of Primordial Spirit to the Unity Realm Stage, this..."

It paused, seemingly thinking over its words, finally forcing out a sentence: "This completely exceeds our understanding."

It lived for hundreds of thousands of years, having seen countless astonishing talents.

Some achieved Golden Core in a hundred years, some achieved Primordial Spirit in a thousand years, some achieved Harmonization in ten thousand years.

Each one was enough to make the world marvel.

But like Lu Qing, it had never seen.

In less than a hundred years, from Six Tribulations of Primordial Spirit to Unity Realm Stage.

What does this signify?

It means Lu Qing’s cultivation speed was a hundred, even a thousand times that of normal cultivators!

It means Lu Qing, in just a few decades, walked a path that others would need thousands or even tens of thousands of years to complete!

This has completely exceeded reasoning, exceeded imagination.

Lu Qing shook his head, not explaining much.

He certainly wouldn’t tell them he broke the Nine Tribulations of Primordial Spirit limit, reached an unprecedented, unknown Twelve Tribulations!

This secret, he temporarily didn’t want anyone to know.

If the Old Cyan Dragon and the others knew he not only achieved Harmonization but reached the Twelve Tribulations level before breakthrough, they would likely be even more shocked, to an immeasurable degree.

The Nine Tribulations of Primordial Spirit was already acknowledged as the limit in the Cultivation World.

Nine is the ultimate number; this is the Heaven and Earth Rules.

No one has ever broken this limit, reached the Twelfth Tribulation.

But Lu Qing did it.

He used his comprehension and opportunity to forcibly break the limit of the Great Dao, took three extra steps in the Primordial Spirit Realm.

These three steps, each was unprecedented.

Such matters that defy reason, speaking of them would only add trouble, let alone for the Old Cyan Dragon and the others to accept them.

So Lu Qing simply smiled, not responding.

At this moment, the Black Bull suddenly asked: "Ah Qing, what Great Dao did you harmonize with?"

Its round eyes were full of curiosity, mixed with some expectation.

In the Black Bull’s view, Lu Qing’s aura was so terrifying, able to bring them such immense pressure. The Divine Thought harmonized with during breakthrough must be the Great Dao, and surely a very strong Great Dao, not possibly an ordinary "Dao."

After all, Harmonization is harmonizing with the Dao.

In the Primordial Spirit Realm, cultivators comprehend the Heaven and Earth Rules, understanding various Daos.

Those Daos vary in strength, depth.

Some Daos point directly to the origin, vast and boundless, others are mere superficial, shallow.

By the time of breakthrough, cultivators must choose one Dao, harmonize Divine Thought with it, thus step into Unity Realm Stage.

The stronger the harmonized Dao, the stronger the post-breakthrough power.

This is basic knowledge in the Cultivation World.

If harmonizing with a common minor Dao, then post-breakthrough it is just an ordinary Unity Realm Stage, with limited power.

If harmonizing with the Great Dao, then post-breakthrough it is a true powerhouse, able to crush those in the same rank.

And if harmonizing with a supreme Great Dao that points directly to the origin...

Then the achievements are simply immeasurable.

So the Black Bull really wanted to know what Dao Lu Qing harmonized with to make him so formidable immediately after breakthrough.

Upon hearing this, the Old Cyan Dragon and Ming Feng also stared at Lu Qing, eyes full of anticipation and curiosity.

They too were eager to know the answer.

Lu Qing, seeing their looks, found it somewhat amusing.

Their gazes were like a group of children waiting to hear a story, faces full of anticipation and curiosity.

Even the Old Cyan Dragon, such a creature that lived for hundreds of thousands of years, showed such an expression at this moment.

He didn’t keep them in suspense, slightly moving his mind.

In the next instant, an unusual aura emerged from his body.

That aura was infinitely mysterious, seemingly containing the ultimate mysteries of the universe.

It was profound, vast, enduring, making anyone who sees it feel awe.

And more astonishingly, within that aura, various different meanings were simultaneously manifested.
