Every cycle of absorbing Essence Energy caused their meridians to grow even more powerful, for their internal organs to elevate to a new stage of resilience, and for the vortex formed within their dantian to expand out even more, becoming a boundless wellspring.
To advance through the Mortal Awakening Realm requires one to comprehend simply 3% total of Essence Energy. This rudimentary part of Essence Energy is called Spirit Qi, the most basic aspect of Qi energy cultivators can use.
But though it's the most basic aspect, comprehending even this small amount of profound principles would take an average cultivator years, if not dozens of years, to reach the middle layer of Mortal Awakening.
A cultivator needed both to comprehend this stage of Essence Energy and to fill their dantian to the very brim with Spirit Qi. Once the Spirit Qi turned into a perfect vortex at every corner of the dantian, only then would one have achieved the peak of Mortal Awakening and be prepared to reach the Essence Gathering Realm.
Lei Jin and Lei Ya were casually filling up their dantian without an issue, advancing through the layers of Mortal Awakening realm as if it were a simple walk in the park.
In their comprehension, however, something striking occurred for the siblings.
'Hm?' Lei Jin furrowed his brows. Upon studying deeper into the world around him through the principles of the Beloved Flowing Art, his Spirit Sense felt an undeniable pull, an unstoppable calling from the very depths of his soul.
Lei Jin's Spirit Sense naturally focused on this unstoppable pull, drawn by an irresistible force. His entire being trembled at that moment, not from fear, but from the sheer, overwhelming power he sensed.
Information began flooding his brain at light speed, a torrent of knowledge. He didn't know how or why, but what appeared to be a manual of some sort emerged in his consciousness, its presence radiating an ancient, terrifying might.
This manual… simply overwhelming.
Even for how calm Lei Jin had previously been, this nearly took all of his breath away. The sheer presence, not even an aura, only one word could describe… invincible.
Lei Jin wasn't even sure what was the peak of power in this world. And yet he was absolutely sure just this manual alone could break apart planets and stars into sheer space dust, obliterating everything for miles.
There were words, various symbols, and signs carved along this manual, but Lei Jin could barely understand anything beyond a primal sense of its terrifying power. Yet, a small portion, seemingly highlighted by his awakened bloodline, was perfectly clear.
The name of the manual was boldly titled, "Thirteenth Heavens Thunder God Bloodline."
And directly below that, a skill, radiating an aura that made his very soul hum, was titled, "Godly Lightning Force."
Reading this skill caused Lei Jin to inhale another cold breath, a shiver of exhilaration, not fear, running down his spine.
From what little he could decipher, the skill described that upon stimulating the power of his bloodline, he could unleash a single layer of Heavenly Thunder God Lightning. A simple, single lightning layer of this force would cause his entire being—his physical strength, his Essence Energy output, his speed, his spiritual fortitude—to be amplified by a staggering 50 times!
Additionally, this special lightning possessed the inherent property of bypassing most ordinary defenses, making every strike of lightning an absolute terror to face, a direct assault on the very essence of an opponent.
That was all that Lei Jin could read for now, the rest a blur of incomprehensible cosmic script. But just this amount caused endless, intoxicating joy to spring within him.
Fifty times!
Now, Lei Jin wasn't sure how much "50 times" would translate to in actual combat, as he had never truly fought in this world yet, but he could instinctively tell his combat prowess was already demonic, a force of nature.
His bloodline was already causing his foundations—the very core of his Essence, Physical, and Soul energies—to be dozens of times stronger and purer than the average cultivator, or even the so-called "genius" cultivators of this realm.
And with such an improved, pristine foundation, combined with the raw amplification of the Godly Lightning Force, it would produce a devastating, utterly overwhelming effect. Furthermore, as his cultivation increased, with better foundations and the potential to unlock more layers of this Godly Lightning Force, just how much could his combat prowess truly increase?
Lei Jin couldn't tell at this moment. But it wouldn't take a genius to know that his possibilities for the future were boundless, stretching into infinity.
This same amount of shocking, world-breaking revelation was also occurring within Lei Ya. Her Spirit Sense, connected to her own soul, was in absolute awe by the terrifying information blooming within her consciousness.
The Myriad Spirit Resonance Physique.
Such a physique allowed her to completely resonate with not just the immediate world around her, but the natural universe itself. She could forge a perfect, harmonious connection to the universe in all aspects, to its various types of energies and Dao Laws.
In this merging, symbiotic fusion, her Essence Energy absorption speed became beyond perfect, her comprehension became higher than the stars themselves, and her foundations would make even the highest beings kneel down in shame, so flawlessly pure and stable were they. She could amplify the power of her Spirit Qi to the maximum limits her body and soul could intake, which at her current level was around a staggering 10 times!
Additionally, to those she had a profoundly deep connection with—like her brother, Lei Jin—Lei Ya could resonate her amplified Spirit Qi to her partner, causing them both to experience the amplified boost of power!
In this case, not only was her combat prowess alone terrifying, especially when her cultivation grew to greater heights, but when she was connected with someone, they could form an absolute nightmare of a team!
Lei Ya obviously knew that with her brother and this unique connection, dominating whatever they wanted would be a simple process. And naturally, her physique had many more uncovered abilities that she could only find out more in the future, each promising another leap in power.
Such earth-shattering revelations caused time to soar by in a flash, the outside world fading into insignificance. They didn't know when, but the siblings were awakened with a startled jolt, a primal surge of power erupting from their very beings.
'Chi!'
A radiant flash engulfed the room, a blinding burst of pure Essence Energy. The very floor cracked under the sudden pressure, the air turned impossibly thick, and an aura potent enough to tear through anything wanted to break out of the confines of this room.
Two pairs of terrifying eyes could be seen within the storm of energy, two pairs of sharp, predatory gazes that would unnerve even demons. And with a wave of their hands, a synchronized, instinctive motion, the siblings cleared away the chaotic burst of their breakthrough, forcing the overflowing energy back into their bodies.
Truthfully, they were already subconsciously suppressing the chaotic energy of their breakthrough; otherwise, the entire room and any rooms close to it would've been utterly obliterated.
"Hehe~" A soft giggle escaped Lei Ya's lips, quickly blossoming into a full, throaty laugh that boomed with newfound power. "Hahaha!! Look at us now!"
She stood up, stretching languidly, causing her joints to crackle with the power of explosive Spirit Qi. Excitement coursed throughout her entire body, making her vibrate with barely contained energy. She clenched her fist, looking down at them, feeling as if a simple punch from her could obliterate a large stone building into utter dust.
"Quite amazing indeed…" Lei Jin similarly stood up, power filling his every movement, a calm, satisfied smile on his face.
He sensed it, a profound understanding settling in his mind: he and Lei Ya had now reached the 6th layer of Mortal Awakening. A feat that would take even a talented Inner Core disciple months, perhaps even years, to achieve, even with a powerful Spirit Grade Art, potent Spirit Grade resources, and dedicated cultivation havens to boost their comprehension and bodily absorption speed.
But these two siblings merely used a few days, all on their own innate effort and comprehension.
As Lei Jin pondered in thought, Lei Ya flicked a smiling glance towards her brother. "Say, Jin, I know for a fact you also came upon a world-breaking revelation during cultivation. I mean, it's the only way to explain how we're turning from common trash to heaven-defying geniuses. I also came upon my own revelation."
Lei Jin nodded. There was no need to keep secrets. Sure, his own previous consciousness had only known Lei Ya for a few days. But through merging into this new life, Lei Jin could feel it, no, experience it. This unbreakable bond to his sister that wouldn't break even in death.
Thus, he said, "Come, let's compare notes. We can make better plans once we have everything laid out…"
Lei Ya excitedly nodded, her eyes sparkling. The siblings began to eagerly discuss their findings, Lei Jin detailing his Thirteenth Heavens Thunder God Bloodline and Lei Ya with her Myriad Spirit Resonance Physique.
One that crazily boosted his prowess, and the other that matched that and boosted both of their prowess beyond belief.
Lei Ya's smile almost split across her face. "Heavens… this is amazing! This—this—" For a moment, her expression faltered. Concern grew in her tone as she crossed her arms, her brow furrowing. "How and why? From as far as I can remember, our bloodline and physique might have been better than the average fool, but that's about it. Why are we suddenly uncovering this power that would make even gods go green with envy?"
Lei Jin similarly focused for a moment, his mind recalling everything it could. The fragmented pieces of his current life and the vivid memories of his past life.
Out of everything, the most strange aspect of his life were those recurring, strange visions. Visions that detailed a man continually going against heavens, beasts far beyond imagination, and worlds that couldn't be described in mere words.
Lei Jin slowly spoke, his voice thoughtful, "The only major thing that happened to us was that Long Tian framing us with a crime to get punished with slow cultivation for a few days. But the seal the Elder put on us was just average at best… something for any other disciples."
"Mn. Even for childhood, it was nothing special. I can barely remember our so-called parents. That Lei Family obviously wanted nothing to do with us…" Lei Ya nodded, though Lei Jin could see it, his sharpened senses detected an unconscious uncertainty within the depths of Lei Ya's eyes. As if she truly believed her words, but something felt off saying it, a subtle dissonance.
Lei Jin filed it for later, a mystery to unravel when they had the power to do so.
