Two days later.

Following an outburst of powerful aura, Li Yun opened his eyes and completely finished his cultivation.

Driven by the brand new Primordial Unity Skill.

His entire body's Inner Force had completely transformed, thoroughly breaking through the limit of first-grade Inner Force, officially stepping into the Realm of super first-grade, cultivating the so-called Origin Inner Force mentioned in Fatal Reversal of Origin.

However, this kind of Inner Force was clearly somewhat different from what was mentioned in Fatal Reversal of Origin, possessing a strong personal style, so Li Yun simply called it Primordial Chaos Inner Force.

After all, it was cultivated through the Primordial Unity Skill, and it was almost impossible for others to imitate; even if the Primordial Unity Skill was given away, others would likely find it difficult to comprehend and unable to cultivation it.

It could only be considered an Inner Force quality unique to Li Yun.

Calling it Primordial Chaos Inner Force wasn't a big issue!

And this Primordial Chaos Inner Force, in Li Yun's opinion, could be described with one word: Strong!

Generally speaking, Inner Force is intangible, while True Qi is tangible.

The naked eye cannot see the specific existence of Inner Force, but after this Primordial Chaos Inner Force was cultivated, it had broken this rule.

It even allowed Li Yun to possess a ability only available to Martial Artists above the True Qi Realm – Internal Sight.

Under Internal Sight.

Li Yun's entire spirit was contained within, all his vision focused internally, as if seen by the naked eye; he could clearly see the Primordial Chaos Inner Force presenting a half-black, half-white appearance, flowing within his body like a river, surging like a torrent, with a majestic aura.

But when he concentrated his spirit further, delving into the depths of the Inner Force to observe, he would find that within this half-black, half-white Inner Force, countless subtle particles of various colors were contained.

Some were crimson like fire.

Some were azure like water.

Some were green like wind.

Some were golden like the sharp edge of a precious sword...

And so on.

Gathered together, they were as brilliant as a rolling rainbow.

These different elements existed simultaneously within the Inner Force, not appearing chaotic or conflicting, but rather possessing unique charm, while simultaneously emitting a strange primordial aura, full of vitality.

This was precisely what had been refined through Li Yun's own life Origin.

But it was different from what Fatal Reversal of Origin stated.

The principle in Fatal Reversal of Origin is to consume the Martial Artist's life Origin, using life Origin, this highest level of natural energy in the human body, to drive the refinement of Inner Force quality.

The Origin Inner Force refined could reach the threshold of breaking the limit of first-grade Inner Force quality, but it could not nourish its own life Origin.

It was purely consumptive.

Of course, the perfected Realm of Fatal Reversal of Origin did indeed consume far less life Origin than the initial Entry-Level, but consumption is consumption; the super first-grade Inner Force gained based on consuming life Origin was ultimately a flaw.

Primordial Chaos Inner Force, however, was not purely consumptive.

Because it could provide nourishment in return.

It also used life Origin to open the door to super first-grade Inner Force, but it could provide nourishment in return after consuming life Origin, subtly smoothing out this flaw.

Moreover, after Li Yun carefully comprehended this nourishment, he could confirm that its effect was actually slightly greater than the consumption of life Origin.

That is to say, as the Primordial Chaos Inner Force grew, this nourishment would also be strengthened, thereby further enhancing life Origin.

One subtraction, one addition... this had already elevated the Primordial Unity Skill to a level that left Fatal Reversal of Origin at least ten streets behind, they were no longer comparable.

It could be said to be exquisitely profound, truly a divine skill!

On this basis, Li Yun's understanding of the Strength Refinement Realm was even elevated to another height.

He also gradually gained a glimmer of inspiration for creating another method for condensing Inner Force, one with stronger adaptability and higher quality, similar to how he created the Divine Martial Eighteen Stances.

However, the method for condensing Inner Force was more complex than Body Tempering Stance Training methods.

It required more accumulation.

For the time being, Li Yun didn't intend to create something just for the sake of creating it, nor was he in a hurry to create this thing.

He would just treat it as giving everyone some time to adapt.

After all, it hadn't been long since he created the Divine Martial Eighteen Stances, and immediately throwing out another self-created Inner Force condensation method, let alone Gu Xiaoxian and Elder Ling, even Sect Leader Chen Jiuxu probably wouldn't be able to keep it together.

At that point, if they suspected he was a spy specially sent by the Heavens Mandate Sect to the Heavenly Martial Sect, that would be troublesome.

After all, he was the only one who cultivated the Reversing Fate Art, he created his own cultivation method, and he had super first-grade Inner Force... Damn, how did all the good things happen to you alone?

Is there really someone so lucky?

To be honest, if he didn't possess the System, even Li Yun himself would have to doubt himself.

"Let's go!"

"I should go to the third floor to get a few True Qi Realm martial arts techniques for some reserves... Then it's time to leave the Martial Repository."

Li Yun took a deep breath, turned around, and ascended the stairs leading to the third floor of the Martial Repository.

After some selection.

He selected several martial arts mental methods for condensing True Qi with Inner Force, as well as several offensive martial arts techniques, forcibly memorizing them with his half-step spiritual Aptitude to ensure they were recorded on the panel, after which Li Yun quickly went downstairs.

He seemed very rushed.

Nothing else, he was just afraid that if he stayed a little longer, he would be reluctant to leave the Martial Repository again.

As a cultivation fanatic, the comfortable environment of the Martial Repository was simply too attractive to him, more fragrant than women, practically fatal.

"Meow—"

Returning to the second floor, preparing to head towards the first floor.

Suddenly, a clear meow entered his ears; Li Yun subconsciously turned his head to look and found a small black cat standing on the sill of the ventilation window.

He wasn't someone who liked petting cats, so he didn't pay it any mind, turned his head back, and continued walking towards the first floor.

After only a few steps, he suddenly stopped.

He looked towards the ventilation window with some alarm, but by then the little cat had disappeared without a trace, as if it had just been an illusion.

"Something's not right..."

"This is the Martial Repository, there are no entrances or exits other than the main door on the first floor; even those ventilation windows are extremely narrow, birds can't get in, let alone cats."

"How did that black cat get in?"

"Could it really just be an illusion?"

Li Yun's face showed some surprise and doubt; he unconsciously turned his head, his gaze sweeping over every corner around him, but he saw no black cat at all.

He had to suspect that he had really seen things.

He shook his head, decided not to think about it anymore, and continued downstairs.

He never expected.

Just as his steps moved, his right shoulder suddenly felt heavy.

A clear meow suddenly sounded in his ear; Li Yun instinctively turned his head, looking at the black cat that had suddenly appeared on his right shoulder at close range, almost clearly seeing his own face, full of fright, clearly reflected in the black cat's bright, golden eyes.

In this instant.

Li Yun was so startled that his entire body directly jumped over three meters high on the spot, and his left hand even swung out a palm, fiercely slapping towards the black cat, wanting to sweep it away.

However, this sweep hit nothing.

With a light leap, the black cat avoided his left hand, silently landing on the stair railing not far away, its hind legs squatting, front paws propped, back slightly arched, like a fierce tiger sitting!

Then it meowed twice at Li Yun, its voice surprisingly gentle.

Even stranger, it actually opened its mouth, and in its small cat mouth, it held a black ring, like a finger ring!
