Developing the cultivation technique didn't take Su Cheng much time.
Aside from his abundant knowledge and relevant experience, the biggest reason was Qian Renxue's exceptional foundation.
Not to mention her innate level twenty soul power, which provided a far superior soul power accumulation compared to her peers, as well as the two extremely powerful innate domains she acquired upon becoming a Soul Saint.
Even the integration of her two distinct souls had already naturally begun to interact with each other.
One could say that even without Su Cheng's help, she had the chance to further advance her innate cultivation technique on her own, though it would take her several more years.
The exclusive cultivation technique Su Cheng devised for Qian Renxue was named "Cangming Transformation."
To truly achieve the state of "using one's own heart to replace the heart of heaven, and then using the way of heaven to determine the way of humanity," the key lies in the word "Transformation."
Qian Renxue's self-created soul skill had lofty and extraordinary ambitions.
However, the continuous process of understanding it was not without danger for her.
As Su Cheng had previously mentioned, while the way of heaven is constant, the human heart is fickle. Achieving the replacement of the heart of heaven with one's own heart is no easy task.
More likely, one's own existence would be overwhelmed and overturned by an extreme will.
Fortunately, Qian Renxue possessed several extraordinary advantages.
The first was her temperament.
Her noble birth brought exceptional talent, her unique childhood environment and family upheavals, her undercover experiences during her teenage years, and the enormous impact of her first simulated world's memories combined with her accumulated knowledge.
These factors forged her resolute and exceptionally extreme character.
The second advantage was the self-regulation between her twin souls.
If a conflict arose in the process of implementing her principles, it would deepen her self-awareness and strengthen her humanity.
Therefore, unlike Su Cheng's own cultivation technique, which focused on refining the mind, Qian Renxue's Cangming Transformation centered on cultivating the heart.
By stabilizing her disposition, her twin souls could naturally transform and integrate with each other, achieving mutual elevation.
Three months later, in Su Cheng's room.
Qian Renxue's main body, dressed in black, and her primary personality's spirit body, dressed in white, sat cross-legged facing each other with solemn expressions.
Golden and black light circulated, enveloping the two.
Simultaneously, tiny lights appeared on them, making them look like twin goddesses, exuding a mysterious aura.
Su Cheng stood nearby, watching them while also releasing his martial soul and innate domain. He stabilized their state and confined the energy fluctuations within the room to prevent any accidents.
"Are you ready?"
As they nodded slightly, black and golden flames simultaneously ignited on their bodies, then slowly converged…
"Hiss—"
The moment the flames intertwined, they merged into a single flame, expanding several times in size.
With Qian Renxue's current accumulation, either soul alone was still far from enough to independently condense the embryonic form of innate power.
But if they joined forces, there was a slight possibility.
After all, after three months of cultivation, their combined soul foundation far exceeded that of ordinary people.
However, despite having two exceptionally strong souls, they shared only one body, necessitating a trigger.
Under Su Cheng's guidance, they used their own vital energy as fuel, igniting it with soul power surpassing their level.
Soon, their vast soul power began to quickly merge…
Before long, a powerful energy fluctuation emerged between the two facing each other.
The flame, suspended in the air, burned intensely, with its powerful energy even faintly impacting the solid barrier Su Cheng had constructed with his domain.
But unlike the previous soul power flames, this one combined vital energy, soul power, and soul strength into innate power.
Unlike Su Cheng's colorless and formless innate power, this flame was a blazing white, exuding a vast and ruthless aura.
After a few breaths, the unstable flame quickly extinguished.
The two facing each other also rapidly weakened, their soul power nearly exhausted.
Yet their expressions were exceptionally exhilarated.
After truly using that power, they could sense its formidable nature.
It was a force entirely different from soul power, on a completely different level, incomparable to the latter.
"Huh, what is this?!"
At this moment, Su Cheng's eyes suddenly widened slightly, a hint of surprise and bewilderment appearing on his face.
Qian Renxue's process of condensing the embryonic form of innate power had proceeded without any unexpected incidents.
When that strand of blazing white flame appeared in Qian Renxue's hand, an unexpected change occurred in Su Cheng himself.
The seventh spirit ring under his feet, which originally displayed a pale pink color, seemed to fade further, becoming more transparent.
Even the layer of crystal-like, beautiful light dimmed somewhat.
However, these were merely superficial changes.
The crucial point was that the origin power within his seventh spirit ring had increased!
Though the increase wasn't significant, nowhere near the initial drop of origin power, the sensory impact was equally apparent.
As a sort of amplifier, even a tiny increase in the origin power within the spirit ring could produce a remarkably substantial effect.
"Could it be because..."
Staring dazedly at the two graceful figures in front of him, silently adjusting their states and each with a serious expression, Su Cheng took a deep breath.
He recalled that in the simulation, after completely breaking through, he had sensed a subtle, almost imperceptible, closeness and approval from the entire world.
Calming his slightly excited emotions, Su Cheng pondered silently, "Is this a reward from the world? Maybe it requires further validation..."
When a new path of cultivation emerges in the world and more people follow it, could it subtly influence the world itself?
Could this be why the so-called "origin power" was injected into his body?
He planned to test this hypothesis.
The source power greatly enhanced his abilities, and if more people mastering the cultivation of innate power could help him accumulate source power, it would be critical to focus on this.
Even the future plans of the Spirit Hall across the continent would need his full commitment.
He had initially intended to promote the cultivation technique as a side project.
But now it seemed that it could significantly aid his own improvement.
Given this, he would have to adjust his subsequent plans.
The importance of the Spirit Hall instantly rose to a very high level.
To promote a cultivation technique effectively, support from a powerful organization was essential.
Otherwise, considering the fragmented and contentious state of the continent, numerous obstacles would arise.
Such an endeavor clearly required more than just sheer strength.
Su Cheng himself didn't have the energy to suppress conflicts everywhere.
"Let's start with the internal members of the Spirit Hall. At least confirm if it's really related to this.
"However, the young spirit masters in the Spirit Academy won't show results in the short term. Their foundation is lacking, and they are far from merging innate power.
"Qian Daoliu, as a guardian of the gods, might not be suitable, but Bibi Dong might be. Should I find an opportunity to let her try? Though the power of the Rakshasa God could be a problem…"
"Teacher, I succeeded!"
Moments later, as the two graceful figures simultaneously opened their eyes and looked at Su Cheng with sparkling eyes, he was pulled out of his thoughts.
Su Cheng temporarily set aside his contemplation about the origin power and smiled back at them. "How do you feel?"
"Teacher, you're amazing," Qian Renxue marveled. "The level of this power is no less than the Angelic God Power, and it's much easier to control."
"Of course," Su Cheng nodded. "Divine power not only integrates the power of faith but also involves the nature of the divine position. Most of it isn't gained by oneself. Innate power, however, is entirely self-derived, making it naturally easier to control."
"I see." Qian Renxue's face lit up with understanding.
"Keep practicing diligently. Once you master this power, there's no need to become a god and be bound by a divine position. Moreover, having reached this step in your cultivation, you've overcome the most challenging hurdle. From now on, it's just a matter of gradual accumulation. Given your talent, it shouldn't take long." Su Cheng said seriously.
"I understand."
As these words were spoken, the figure in white gradually disappeared in front of the other two.
The initial fusion of innate power had greatly drained her soul strength.
Without a physical body, her spirit form could hardly be maintained.
Moreover, it was clear that the second personality currently had greater control over the body, so the primary personality had to return within.
However, this situation was only temporary.
As the cultivation of the Cangming Transformation continued and their mastery of innate power deepened, the balance between the two personalities would become more equal.
When that time came, determining a victor would be far more challenging.
Eventually, when the mastery of innate power reached the second stage of Su Cheng's Eternal True Body.
Mobilizing the vital energy of the main body to temporarily construct a shell to house the soul wouldn't be out of the question.
