Chunibyo in Cultivation World

Outside the outer sect of the Sacred Land of Lingxu, Xu Yuanwen sat cross-legged on a meditation mat, patiently cultivating.

As an undercover agent of the Blood Fiend Sect, Xu Yuanwen had been sent into the Sacred Land of Lingxu since childhood.

It had now been six hundred years.

At the age of five hundred, he successfully overcame the Nascent Soul Tribulation, achieving the most ordinary one-mark Nascent Soul.

Xu Yuanwen’s aptitude was not particularly good — merely a superior-grade Three Spiritual Roots. To achieve Nascent Soul Realm was already a matter of great fortune.

But Xu Yuanwen was perfectly aware of why he had been able to break through.

After all, as a disciple of the Sacred Land of Lingxu, he received a monthly stipend from the sect.

Meanwhile, as a spy of the Blood Fiend Sect, he received another set of benefits from that side as well.

With both incomes combined, he naturally possessed far more cultivation resources than ordinary disciples of the Sacred Land.

At least in terms of wealth, Xu Yuanwen was extremely satisfied.

Moreover, in his eyes, he was fully aware that the Blood Fiend Sect and the Sacred Land of Lingxu were unlikely to truly wage war. Because of this, he could safely profit from both sides.

Xu Yuanwen even believed that with the support of both sects’ stipends, he might someday glimpse the Spirit Transformation Realm.

“Sigh, my cultivation’s getting a bit slow. Should I sell some intel to the Blood Fiend Sect to get them to send me more resources?”

Xu Yuanwen slowly opened his eyes, thinking as such.

Just at that moment, he seemed to sense something and hurriedly walked out of the main hall.

“That is…”

With his strength at the Nascent Soul Realm, his perception was far sharper. He could clearly sense the spiritual fluctuation atop Heaven’s Gate Peak.

Xu Yuanwen could already determine that someone had successfully reached Foundation Establishment — and this violent surge of spiritual energy could only belong to the Hundred-Day Foundation.

“Heaven’s Gate Peak… could it be him?”

Xu Yuanwen couldn’t help but recall the mission the Blood Fiend Sect’s Vice Sect Master, Hun Yuan, had issued a hundred days ago — to send a False Spiritual Root disciple disguised as a Heavenly Spiritual Root into the Sacred Land of Lingxu.

As for the Blood Fiend Sect’s true intentions, Xu Yuanwen had no idea what they were planning.

“A Hundred-Day Foundation, huh? Looks like the Blood Fiend Sect really went all out this time.”

“Are they preparing for something big?”

Xu Yuanwen pondered silently for a moment.

“At this rate, I might not be able to keep drawing both stipends for long.”

“Still, since he’s my fellow operative, I should take the chance to communicate with him more.”

Xu Yuanwen did not believe for a second that Vice Sect Master Hun Yuan would go through so much trouble to plant a False Spiritual Root spy in the Sacred Land — and even help him achieve a Hundred-Day Foundation — if it were a simple matter.

“Could that brat be Hun Yuan’s illegitimate son?”

“After all, he’s a mighty expert of the Out-of-Body Realm, yet he somehow fathered a False Spiritual Root child and even went through all this trouble scheming against the Sacred Land of Lingxu…”

“Having connections sure makes things easier. Unlike me—sigh—I’ve got no background, forced to live as a spy, barely scraping by with two stipends just to reach Nascent Soul Realm.”

After lamenting for a while, Xu Yuanwen returned to the hall to resume his cultivation.

……

When the news of Li Tianwei’s Hundred-Day Foundation spread throughout the Sacred Land of Lingxu, all the disciples instantly understood that another peerless genius was about to rise.

Over the years, aside from Bai Muxu’s generation, the Sacred Land of Lingxu had suffered greatly under the suppression of other sects in the Northern Spirit Domain.

Now, with Li Tianwei’s appearance, they finally had a chance to break free from that pressure.

Not only the disciples were excited, but the elders and peak masters of the Sacred Land were also thrilled—though deep down, they couldn’t help feeling a bit regretful.

After all, this kind of prodigy didn’t end up under their peaks, but under Bai Muxu’s instead.

After Li Tianwei completed his Hundred-Day Foundation, Bai Muxu immediately ran off to visit all the other peak masters who weren’t in closed-door cultivation, dragging them into tea gatherings and chess matches.

And his mouth hadn’t stopped running since.

He boasted endlessly about how Heaven’s Gate Peak now had “two supreme geniuses under one roof,” both achieving Hundred-Day Foundations, “invincible under heaven,” perhaps even destined to “shatter the current age.”

Eventually, when Bai Muxu tried to visit more elders for tea, he received only one reply from each: in secluded cultivation or out for training.

Meanwhile, at the center of this storm, Li Tianwei stayed quietly inside his Heaven’s Gate Peak cave residence.

At this moment, he was holding the Five Intentions Converge to Heaven Art, studying it carefully.

Although he had suffered losses from the Heaven-Origin Dao Foundation Method before, Li Tianwei, being someone from another world, knew one thing — that “a towering building always starts from the ground.”

It was just like his past life’s studies: even if he could already understand all elementary-level knowledge—mathematics, language, and logic—enough to tackle middle school, high school, and even university subjects, that was never an excuse to despise the basics.

Everything was built upon foundations.

The Heaven-Origin Dao Foundation Method, though flawed, became perfectly suited to him once he refined it through his unique understanding, allowing him to achieve the Hundred-Day Foundation.

Thus, there was no such thing as “bad knowledge” — only “bad users.”

Li Tianwei truly didn’t look down upon the Five Intentions Converge to Heaven Art.

As long as he slightly modified it, it could fit him perfectly.

“Immortal Tianyuan, my lord, please don’t blame me. That vile demon was too despicable, too shameless — he threatened me! Since I’m bound to him, I had no choice but to hand him this Celestial Art.”

“For the sake of your inheritance, my lord, I must endure this humiliation. Once the opportunity arises, I will ensure that the Five Intentions Converge to Heaven Art is passed on to a true successor, so the legacy will never perish!”

The Book Spirit looked at the three-petaled circular sigil between Li Tianwei’s brows and continuously hypnotized itself inwardly, letting him handle it freely.

As for Li Tianwei, flipping through the Five Intentions Converge to Heaven Art, he quickly grasped its general framework.

He had to admit that this Celestial Art was far more complex than the Heaven-Origin Dao Foundation Method.

To be called a Celestial Art, it not only refined spiritual power but also contained intricate combinations of countless spells and techniques.

At higher stages of cultivation, one could even train a divine ability through this method.

However, to learn that divine ability, one must first master thousands of lesser spells—only by perfecting them could they interlock into a single node to unleash the divine power.

It was just like mathematics — from addition, subtraction, multiplication, and division, to linear equations, quadratic functions, geometry, and various logical deductions—only through mastering the fundamentals could one tackle the higher mysteries like advanced calculus and algebraic topology.

Undoubtedly, the Five Intentions Converge to Heaven Art could be cultivated all the way to ascension, with each stage from Foundation Establishment to Golden Core clearly defined.

Within that single small book were, in fact, thousands of intertwined scriptural variations.

Li Tianwei found that perfectly reasonable.

After all, in his past world, even a single aircraft’s composition data and material specifications, if printed on paper, could fill an entire football field—and only by thoroughly understanding it could one hope to build a fighter jet.

This Celestial Art, similarly, represented the pinnacle of the cultivation world—so naturally, its complexity was only fitting.

With his advancement into Foundation Establishment, Li Tianwei’s physical body and cognitive abilities had increased to an unimaginable degree.

A cultivator’s mind was now like a supercomputer.

Just by scanning a few pages, most of the content was already imprinted in his memory.

Determined not to repeat the mistakes he made with the Heaven-Origin Dao Foundation Method, Li Tianwei decided to modify this technique thoroughly to suit himself.

He casually took out the corrected version of the Heaven-Origin Dao Foundation Method that he had perfected atop Heaven’s Gate Peak and began comparing it with the Five Intentions Converge to Heaven Art.

The Book Spirit had long fallen silent.

Seeing that Li Tianwei didn’t rush to cultivate but instead retrieved another book from his storage ring, it couldn’t help but grow curious.

When it saw the title Heaven-Origin Dao Foundation Method, it wondered what exactly Li Tianwei was up to.

Then it extended its senses to inspect it—and was utterly dumbfounded.

Dense text filled every page—intricate markings, mathematical data, elaborate classifications, and countless corrections.

“Ah! Th-this… this…”

“Fission… atoms… collisions…”

“The operation of Five Elements, harnessing mutual-restraining principles to collide, ignite spiritual energy, and fuse it into the body…”

As a Celestial Art, it was born from an immortal’s boundless wisdom—though the Book Spirit itself had no combat strength, its comprehension of cultivation methods was unrivaled.

Yet the Heaven-Origin Dao Foundation Method that Li Tianwei presented before it shattered its worldview — yes, utterly shattered it.

Various compositions defying the conventional laws of cultivation, Five-Element cycles, bizarre numeric models—all lay before it.

At that moment, the Book Spirit had only one question: Could this modified Heaven-Origin Dao Foundation Method even be practiced?

Carried by this burning curiosity, the Book Spirit was irresistibly drawn in.

It followed Li Tianwei’s pace, flipping page after page, desperately trying to comprehend the logic within.

As it did so, it began to simulate possibilities within itself—and thus, its other function as a Celestial Art’s spirit emerged.

Celestial Arts with sentience could break down cultivation, simulate it, and substitute practice on behalf of the cultivator…
