As the pure energy from the Profound Crystal Bead flowed into Cain's Qi Sea, immediate changes simultaneously occurred throughout his entire body and mind.
To his Qi Veins, muscles, tendons, and bones, Spirit Qi was circulating at a breakneck pace.
To essentially every part of his body, Spirit Qi was smoothly flowing out like a stream of water. These streams of Spirit Qi connected with Profound Crystal Bead energy, creating a second energy link within Cain's body.
Within just seconds, two energy links assimilated within Cain's body.
The Profound Crystal Bead's pure energy simultaneously absorbed into his internal body and his Qi Sea, pushing Cain's body to break past its borders.
In no time at all, the energy accumulating within Cain's body reached a breaking point.
Just one more step, and he could directly enter an entirely new realm of prowess.
However, before Cain could naturally do so, an invisible barrier suddenly formed within his Spirit Sense.
This invisible barrier released an indomitable force, making it impossible for Cain's body to breakthrough on its own.
And at this time, Cain wasn't even aware at all of his bodily changes. Instead, his entire focus was on this suddenly invisible barrier.
Before this happened, Cain already felt like his mind was touching upon a new form of energy. An energy that felt far purer and refreshing compared to Spirit Qi.
When attempting to perceive this new form of energy, Cain didn't feel confused at all. Rather, it felt like he was studying textbooks he already knew all the answers to.
In the few seconds he delved into this energy, Cain felt his entire mental psyche improve at a rapid rate.
With his speed, he was nearly about to take a step in fully comprehending this energy.
However, before he could do so, that invisible barrier had suddenly formed.
And immediately, Cain knew what this barrier was.
This was the step that separated tens of thousands of average Spirit Opening cultivators.
The Nascent boundary barrier!
Once he breakthrough this barrier, achieving a higher perception than he ever had before, Cain would take the first step in becoming a Nascent Formation Master.
Now to Cain and Kali, this moment just seemed almost too causal for them. All they did was simply fight and absorb Qi energy to quickly reach this boundary.
Taking weeks to comprehend the complex properties of Spirit Qi, taking small steps just to began to understand cultivation that simply didn't exist for the sibling duo.
As they approached the next realm, Cain and Kali kind of felt like this achievement was unremarkable.
However, their thoughts couldn't be further from the truth.
If their Dragon Emperor, grandmother, or anyone in the Huang Imperial Family were to know about Cain and Kali's cultivation speed and comprehension abilities, it would be the outcry of the century!
This kind of Martial Talent would've never allowed Cain and Kali to so recklessly adventure on their own. The resources they would be given would significantly boot their cultivation, taking them to the top in no time.
But, whether or not that method would bring out Cain and Kali's true potential would remain unknown.
And though Cain felt like reaching Nascent Formation wasn't anything remarkable, he was vaguely aware of the kind of mind-breaking reaction this would've caused.
His mind briefly flashed to the amusing reaction his Eldest siblings would give them if they saw them speeding through cultivation like it was just a mere jog.
Their terrified faces popped into Cain's mind for a split second before he quickly refocused on his breakthrough.
At this moment, Cain's Dragon Charm exploded with intense white shine!
The combined pure Dragon God blood essence power within the Dragon Charm started to quickly imbue Cain with unfathomable energy as it sensed his upcoming breakthrough.
Cain's entire body visibly shook. The Dragon Charm's sudden release of power was rapidly accelerating his comprehension speed!
Initially, Cain felt like it would take a couple of hours to breach the Nascent boundary barrier.
Even though his comprehension was at its peak, he still needed to slowly perceive his way into Nascent Qi. Unfortunately, he didn't have the option to dash right through this barrier compared to his other breakthroughs in the Spirit Opening realm.
Of course, this process was entering into a great new realm. It simply couldn't be compared to a small breakthrough within a realm.
Considering all of this, even Cain needed some amount of time to properly reach the Nascent Formation realm.
However, when his Dragon Charm exploded with this new power, his comprehension speed erupted to sonic speed levels!
Now, Cain felt like he was tunneling right to the core of the Nascent boundary barrier.
As time quickly trickled by, the air around Cain and Kali started to violently churn. Mainly around Cain, flashes of intense dark blue rays of energy frequently appeared.
With every flash of dark blue energy, an audible pop echoed out in the room, being as loud as flashes of thunderclaps.
At the same time, waves of powerful energy stormed around the room like a hurricane, causing utter havoc of mess.
However, no matter how chaotic the environment around them got, Cain and Kali never once opened their eyes.
Moreover, nobody in the entire Kong Clan would ever know that two Nascent Formations Masters was coming into existence.
Soon enough, a whole hour passed by.
And at this time, a monumental change occurred within Cain's mind.
'Ka-Cha!'
A resounding shattered of pure new energy broke open in Cain's rapidly evolving mind.
This energy felt incomparably pure as if it came from deep within the most pristine part of the Earth itself.
'So this is Nascent Qi! Truly beyond Spirit Qi….' Cain immediately became delighted.
Indeed, the pure energy he perceives now is Nascent Qi. And upon finally shattering the Nascent Boundary barrier, Cain's entire Qi Sense evolved.
Now, his mind felt thousand times more sharper. Even if it was the most complex of mortal people's subjects, Cain knows he could solve them with only a single glance.
Along with his increased intelligence, Cain could also feel far more presences from his Qi Sense.
Down to even the weakest of presence, Cain's Qi Sense could perceive it all. And of course, this also means he can sense the full, completed form of Nascent Qi.
This stage in the breakthrough process is the half-step level.
If Cain left his cultivation here, he could feasibly call upon Nascent Qi to majorly enhance his attacks. Although, he wouldn't be able to use the Qi energy full power.
Crossing over the half-step level takes time in itself as well. Though a cultivator can now perceive the basis of Nascent Qi, they would need to shatter the first Nascent Formation mental barrier to fully reach the Nascent Formation realm.
Such time constraints naturally didn't exist with Cain.
As he previously did with Spirit Qi, Cain sucked in Nascent Qi towards his body without any resistance.
Also similar to Spirit Qi, the absorb Nascent Qi running through Cain's body converted to a far denser type of energy. In a few seconds, streams of Nscent Qi quickly transformed most of Cain's internal body.
His muscles, tendons, and bones experienced a similar kind of breakthrough. No longer was there Spirit Qi circulating throughout his organs; now everything was getting filled to the brim with Nascent Qi.
And unlike in the Spirit Opening Realm, Cain no longer needed to concentrate on absorbing Qi Energy into specific parts of his body.
His cultivator body transformed to a point where this is just a natural process.
What Cain had to focus on was absorbing Nascent Qi directly into his Qi Sea and begin converting it into a Qi Seed.
This Qi Seed would be formed right at the center of one's dantian, being the proper underlying foundation for all future realms of cultivation.
Spirit Qi had only a tiny portion of Heaven and Earth's Origin energy. This would allow cultivators to build up a solid foundation for the Nascent Formation realm.
Nascent Qi contains the total abundance of Heaven and Earth's Origin energy.
With this type of energy, all cultivators in the world need to form the Qi Origin Seed so that their entire being can have the perfect Origin Foundation.
Extreme carefulness and the utmost care are needed with each subsequent level of the Nascent Formation realm. One wrong move and a cultivator can potentially ruin their future prospect in cultivation.
The first level was the most critical step of the Nascent Formation realm. One has to make sure every drop of their Qi Sea is converted by Nascent Qi, or else, they can never breakthrough.
Even for all the high confidence Kali has in themselves, she repeatedly warns Cain to be extra careful at this critical juncture.
With all this in mind, Cain did his extra best to perfectly breakthrough. Although, he soon realized Kali's worries were unfounded.
Recalling the steps she told him, Cain was an utter natural with converting his Qi Sea. There simply wasn't even the faintest of resistance as Cain filled up his entire Qi Sea with Nascent Qi.
Then, after only a few minutes, Cain felt his Qi Sea, and entire body violently shake!
'Bang!'
A tremendous blast of Nascent Qi vigorously surged out Cain!
The floor beneath Cain shattered into splitters while large wide open cracks tore up the ceiling and walls. Under the might of Cain's heavily dense Nascent Qi, the room nearly broke to bits.
The only thing not affected was Kali. A shimmering white Light wrapped around Kali like a protective aura, shielding her from the chaotic energy burst.
'Perfect, I'm now a full-fledge Nascent Formation master!'
Cain's excitement turned up to a hundred degrees. He was utterly basking in the abundance of raw power coursing at every inch of his entire body.
With just a punch, Cain felt as if he could shatter a colossal metal boulder to powder!
Sensing inside himself, Cain witnessed the complete changes to his dantian.
Now, instead of a gray color sea of Spirit Qi, there was only a considerably large yet vague looking gray seed here.
This was Cain's Qi Origin Seed, the basic foundation for all of his future achievements in this universe.
