Complete Form, Eye of Heaven

Time flowed quietly through the tranquil daily life of the Butterfly Mansion. Since his sparring match with Sanemi and Obanai, Moyu's training had become increasingly focused. He spent more time on deep meditation and precise control of his power. The execution of the Void Style "Zi" had become more stable. Although the energy consumption was still enormous, it no longer felt as difficult to control as it had at the beginning. His use of the Reversal Technique had also become more proficient. Positive energy flowed within his body like warm spring water, nourishing the minor damage and mental fatigue accumulated from the high-intensity training.

His Dragon Elephant Prajna Skill steadily advanced to the peak of the third level. His blood and qi surged like the Yangtze River, his physique was strong and robust. When still, he was as still as a deep pool and a towering mountain, but when he moved, he contained astonishing power. His white hair shone even brighter in the sunlight, making his already aloof temperament even more otherworldly.

That day, as usual, Moyu sat upright on the tatami mat in his room, engaging in his daily, unwavering deep meditation. The "Advanced Mental Strength Meditation Method," combined with the positive energy flowing through his body, made his sea of consciousness clear and bright, and his Mental Energy, like refined steel that had been repeatedly forged, became increasingly resilient and immense.

However, just as they entered the deepest meditation, something unexpected happened!

The six eyes, which had always been as docile as an extension of his body, suddenly began to stir violently without warning! It wasn't external pain, but a roaring and tearing sensation originating from the depths of his soul, as if some boundary had been broken! The massive flow of information no longer poured in clearly and orderly, but like a flood bursting its banks, it frantically and uncontrollably assaulted his consciousness! What he could see was no longer the microscopic world with its fine details, but a chaotic mass of information woven from countless fundamental particles and energy trajectories—enough to drive an ordinary person mad instantly!

"Well...!"

Moyu groaned, a fine layer of cold sweat instantly beading on his forehead, his body trembling slightly uncontrollably. He immediately realized what had happened; the long-awaited evolution of the Six-Eyed was about to begin! The leap from the growth stage to the final, Complete Stage!

This transformation, originating from the depths of the soul, caused energy fluctuations far beyond imagination! An invisible and intangible pressure, as vast as the boundless sky and as profound as the starry sea, spread out like ripples on water from the center of Moyu's room, instantly enveloping the entire Demon Slayer Corps headquarters!

At that moment, whether it was Kyojuro Rengoku, who was instructing his team members while they were sweating profusely, Himejima Gyomei, who Gyomei Himejima in the quiet room, Sanemi Shinazugawa, who was conducting combat training, Tengen Uzui, who was pruning flowers in the garden, Muichiro Tokito on the roof, or even Giyu Tomioka and Obanai Iguro, who were in their respective residences... all the Pillar-level powerhouses suddenly stopped what they were doing and stared in horror in the direction of the Butterfly Mansion!

That aura... felt like a superior, purer, oppressive force, seemingly originating from the very heavens and earth! Like the eye of the heavens, it indifferently looked down upon all living beings, making one feel their own insignificance and tremble from the depths of their soul!

"What... what is this aura?!" Kyojuro Rengoku's booming voice was filled with unprecedented shock.

"Namo... Amitabha..." Gyomei Himejima two lines of clear tears, and stopped turning the prayer beads.

"This fluctuation... is coming from the Butterfly Mansion... What is that Eye Hashira up to now?!" Sanemi Shinazugawa's face contorted with rage as he instinctively gripped his Nichirin Blade.

"A magnificent... and breathtaking aura..." Tengen Uzui put away his nonchalant expression.

Giyu Tomioka silently gazed out the window, his eyes grave. Obanai Iguro, on the other hand, instantly thought of Mitsuri Kanroji, who often visited the Butterfly Mansion, and vanished from the spot in a flash.

The one who felt it most deeply was none other than Shinobu Kocho, who was right next to him.

She was preparing medicine in the pharmacy when that oppressive aura descended. The medicine spoon in her hand clattered onto the table, her violet eyes narrowed sharply, and her delicate body trembled slightly, as if struck by an invisible giant wave. That aura was so close, so strong, carrying a familiar yet completely different coldness and vastness... It was Moyu!

"Moyu- jun...?" Ren's voice carried a hint of panic. Without hesitation, she rushed out of the pharmacy and ran towards Moyu's room. Her heart was filled with worry. Had something gone wrong with his cultivation? Or... had he encountered an unimaginable attack?

Just as this terrifying pressure spread, Moyu, at the center of the storm, forcefully suppressed the surging torrent of information in his sea of consciousness with his powerful willpower and Mental Energy that was now far beyond what it used to be. He knew that he could not complete his evolution here, otherwise the out-of-control energy could destroy the entire Butterfly Mansion, and even affect Nezuko and the other members of the Butterfly Mansion.

"Cang!"

He silently chanted, and without even needing to form hand seals, his understanding of the laws of space became almost instinctive. The space around him slightly distorted, and the next moment, his figure disappeared from the room, appearing as if by teleportation in the depths of the back mountain, far from the main base and rarely visited by people, in the Valley where he usually cultivated.

Almost the instant he left, Shinobu Kocho suddenly appeared at the door of his room.

"Moyu Yu!"

The room was empty, with only the lingering, chilling pressure and a strange, unsettling resonance in the air. The marks of his earlier sitting on the tatami mat remained.

"Left? Went to the back mountain?" Shinobu's heart clenched instantly; the source of that aura had clearly moved. Without hesitation, she leaped out of the courtyard like a purple butterfly, unleashing the "Insect Breathing" technique to its fullest extent, chasing after the back mountain at top speed.

In the Valley, Moyu's six eyes had entered the most crucial stage of evolution. His white hair moved without wind, and his body was surrounded by a visible, distorting vortex of Azure energy. The information storm in his mind grew increasingly violent, his 360-degree field of vision extending infinitely, penetrating the mountain rocks and overlooking the earth. His microscopic perception had increased dramatically, reaching an unprecedented atomic level! Every flow of energy and every structure of matter was presented to his "eyes" with unprecedented clarity.

At the same time, he clearly felt that his control over his spell power had undergone a qualitative change! The "loss" that was unavoidable when casting spells in the past was now almost zero under his enhanced microscopic insight! This meant that, as long as he wanted, he could maintain the automatic defense of the "unlimited spell" almost permanently, and could use killing moves such as "Cang", "He" and even "Zi" more frequently and easily! Of course, this was under the condition that his Mental Energy was sufficient. His understanding of the reversal spell also deepened instantly, and the efficiency of positive energy generation and utilization skyrocketed.

But the cost was equally enormous. The uncontrolled, relentless influx of massive amounts of information, like a never-ending tide, relentlessly assaulted his brain. Even with his current Mental Energy, he felt an unprecedented burden, and mental fatigue pressed down on him as if it were a tangible reality. If he didn't deal with it, he would probably become mentally exhausted from information overload in less than half a day.

In a flash, he swiftly took out a soft, absorbent black cloth strip from his pocket that he usually used to wipe Azure Star, and deftly covered his eyes with it, tying it tightly behind his head.

In an instant, most of his pure vision was blocked. While Six Eyes doesn't rely entirely on sight to receive information, this action acted like adding a filter to the raging information flow. Although it couldn't completely eliminate the problem, it greatly reduced the intensity of the direct impact of the information. The suffocating torrent of information finally became slightly milder; although it continued unabated, it was now within the limits of his formidable Mental Energy. Mental fatigue remained, but it no longer increased wildly.

Just then, a purple figure swept into the Valley like a gust of wind.

"Moyu Yu!"

Shinobu Kocho stopped, panting, her purple eyes scanning the Valley urgently before locking onto a familiar figure in the center. When she saw Moyu's appearance, her heart clenched.

Moyu stood there silently, his snow-white hair fluttering gently in the mountain breeze. But his usually deep, calm, and all-seeing Azure eyes were now completely covered by a black cloth! He stood there, his aura seemingly even more vast and unfathomable than before, carrying a mysterious pressure, yet the black cloth covering his eyes made Shinobu Kocho's heart sink instantly.

In her view, Moyu's eyes... were having problems! Was it because of that terrifying incident just now? Was it a backlash from his cultivation, or some kind of injury she couldn't understand?

"Moyu Jun! Your eyes...!" Ren's voice trembled slightly. She rushed forward, ignoring the chilling energy field still lingering around Moyu, and instinctively reached out to touch the black cloth to check his condition. As a doctor, she knew all too well the seriousness of eye injuries!

Hearing Ren's voice and sensing the undisguised anxiety and worry in her approaching aura, Moyu turned his head slightly to look in her direction. Under the cover of the black cloth, the perception of the six eyes unfolded in another form. Ren's outline, the slightly rapid flow of energy in her body due to her rapid running, and the genuine panic on her face were all clearly reflected in his mind.

He realized that Ren had misunderstood.

"I'm fine," Moyu said, his voice as calm as ever, even possessing an unusual stability, as if the earth-shattering transformation that had just occurred had never happened. "My eyes are fine too."

He raised his hand and gently pressed it against the black blindfold, explaining, "It's just... my eyes are seeing too clearly, I need to rest for a bit."

His tone was calm, yet it contained a convincing power. Especially the phrase "saw it all too clearly," combined with the terrifying pressure that had enveloped the entire headquarters just now, Shinobu Kocho instantly understood something.

It wasn't an injury... it was... his eyes had become stronger? So strong that... he needed to actively shield them to adapt?

The thought flashed through her mind, and the huge weight in her heart instantly lifted, replaced by immense shock and a sense of bewilderment. She looked at Moyu, with his white hair and black belt, standing there, his aura as deep as the sea. Although he was blindfolded, he gave people the feeling that he knew everything.

"So... so that's how it is..." Ren breathed a sigh of relief, patted his chest, and his usual gentle smile returned to his face. However, deep within that smile was a hint of lingering fear and complex emotions. "It really... startled me. Everyone felt that aura just now. I thought..."

"I apologize for making a bit of a commotion," Moyu said calmly, able to see Ren's emotional shift.

"I'm glad you're alright." Ren gently shook her head, her gaze falling on the black cloth. She couldn't help but ask curiously, "Then... will this affect you? For example... your mobility?" She couldn't imagine how Moyu, who had lost his sight, could fight.

"It doesn't matter, I can still see it, just in a different way." Moyu walked towards a rock about half a person's height. His steps were steady and without the slightest hesitation, as if he didn't need to see at all.

He walked to the rock, stretched out his finger, the tip of which was surrounded by a faint Azure light, and gently touched a spot on the rock's surface.

"Click."

With a soft sound, spiderweb-like cracks instantly spread across the surface of the rock, centered on the point where his fingertip landed, before it silently crumbled into a pile of powder!

Shinobu Kocho blankly at the pile of stone dust, then looked at Moyu, who was blindfolded but seemed to know everything around him, her purple eyes filled with disbelief.

Just then, the sound of something cutting through the air rang out one after another.

"Shinobu! What happened?"

"Eye Hashira! What was that aura just now?!"

Obanai Iguro was the first to arrive. His heterochromatic eyes nervously swept over Shinobu, and only after confirming that she was unharmed did he look warily at Moyu, especially at his blindfolded appearance, which made his pupils shrink.

Immediately afterward, Kyojuro Rengoku, Gyomei Sanemi Shinazugawa, Tengen Uzui, Muichiro Tokito, Giyu Tomioka, and even Mitsuri Kanroji arrived, panting heavily. All the Pillars gathered in the Valley, their faces filled with Gyomei Himejima, confusion, and solemnity, their gazes all focused on the center of the arena—on Moyu, the white-haired, black-banded figure with an aura as deep as an abyss.

The sight before them left them speechless for a moment. Moyu appeared unharmed, and even possessed an aura that was more powerful and unpredictable than before, but the black cloth covering his eyes was far too conspicuous and unusual.

"Moyu Boy! Your eyes?!" Kyojuro Rengoku spoke first, his voice filled with concern.

Sanemi Shinazugawa frowned deeply. "Hey! What are you doing? Did you make that terrifying noise? What's wrong with your eyes?"

Mitsuri Kanroji also covered her mouth, her light green eyes filled with worry. "Mr. Moyu, you..."

Faced with everyone's questions, Moyu simply looked at them calmly. Although his eyes were covered, he gave everyone the illusion that they were being clearly watched by him.

"A small breakthrough," he replied briefly, his tone devoid of emotion. "My eyes are fine, I just need to adjust."

Gyomei Himejima a Buddhist prayer in a low voice. He could feel the restrained yet powerful energy emanating from Moyu, which was far more unfathomable than before. "Namo Amitabha... Congratulations, Eye Hashira, on your cultivation reaching a new level." He vaguely understood something.

Tengen Uzui stroked his chin, examining Moyu's new look. "Oh? A breakthrough? And he even got such a fancy eye patch? Looks like he's really become incredibly powerful!"

Giyu Tomioka watched silently, and a slight ripple seemed to appear in Muichiro Tokito's empty eyes.

Shinobu Kocho spoke up at the right moment, explaining for Moyu: "Everyone, don't worry, Moyu- kun's eyes are fine, it's just... his abilities have improved, and he needs to cover them up a little to adjust."

Hearing Shinobu's explanation and seeing that Moyu was indeed acting normally, even giving off a more dangerous feeling, the Pillars, though still filled with curiosity and shock, were somewhat relieved. However, looking at Moyu's blindfolded appearance and recalling the oppressive feeling like divine might just now, everyone understood that this young Eye Hashira had reached a height that they might find difficult to attain.

Sanemi Shinazugawa curled his lip and snorted, "Monster..."

Moyu said no more. He needed time to fully familiarize himself with and stabilize the power of the Complete Stage Six-Eyed One, as well as adapt to the new way of perception in this blindfolded state. He turned to the crowd and said calmly, "I'm fine. Sorry to bother you all. Go back now."

His words carried an undeniable, calm power. The pillars exchanged glances, filled with questions, but knowing it was best not to disturb them further, they left the Valley one after another with mixed feelings.

In the end, only Shinobu Kocho remained in the same spot.

She looked at Moyu. In the moonlight, his white hair and black belt made him stand tall and straight, seemingly blending into the surrounding night, yet also appearing detached from it all.

"Really... don't we need to do another check-up?" Shinobu asked softly, her tone carrying the caution of a doctor.

"No need." Moyu shook her head. "You go back first. I'm fine."

Ren looked at him intently, as if trying to see through the black cloth to the world in his eyes. Finally, she nodded gently. "Okay. Then... take care of yourself. Call me anytime if you need anything."

After saying that, she turned around, and her purple figure slowly disappeared into the night.

The Valley returned to silence. Moyu stood alone, blindfolded, "looking" at this world that was now different for him. The torrent of information became orderly under the filter of the black cloth, and the energy Meridians were clearer than ever before. He slowly raised his hand, feeling the surging, almost imperceptible magical power within his body, as well as the earth-shattering power of the spell that could be mobilized at any time.
