Kage-level Peak Attack

"It... it actually succeeded!"

"In a mere half-hour, you have actually succeeded. This is simply incredible!"

The White Snake Sage turned her massive serpentine body, looking at Keigo Uchiha in disbelief.

"Your body had just begun to petrify, showing signs of turning into a snake. Why were you able to recover from the petrification process in the end? Petrification is irreversible!"

"How on earth did you do it!"

The depths of the White Snake Sage's eyes were filled with shock and... joy!

This speed of cultivation was far too fast. Even as an ancient being, she had only gradually come into contact with natural energy back in the day, mastering it bit by bit. It was only because of the unique characteristics of her body that she did not undergo petrification.

Yet, the speed Keigo Uchiha had just displayed was simply hair-raising!

One must know that even for the fastest individuals, it takes at least a year or more!

The vast, naturally circulating natural energy within the body of the Keigo Uchiha before her left her stunned!

Is this what it means to have just mastered Sage Mode?

Keigo Uchiha's pupils had turned golden, and unlike the orange eyes of Uzumaki Naruto, his were a deep, vivid red, resembling bright red cinnabar paste.

At the same time, Keigo Uchiha's skin had become even fairer and more flawless!

"So this is the Sage Mode of Ryūchi Cave? It is different from the Sage Mode of Mount Myoboku. The Sage Mode of Mount Myoboku involves changes to the face, and only the face, whereas the Sage Mode of Ryūchi Cave involves changes to the body as well."

"The skin tone of the body also undergoes a transformation."

Keigo Uchiha felt the changes in his body, lost in thought.

He frowned slightly, "Perhaps this is due to the different physical characteristics between the snake clan and the toads. The snake's body inherently possesses the ability to interact with the outside world, so the body also undergoes certain mutations."

"However, the less external snake-like transformation occurs, the more successful the Sage Mode is!"

This explained why, in the original story, Yakushi Kabuto had learned the Sage Mode of Ryūchi Cave and mastered it to a high degree, yet it was still not perfect.

True perfection.

Should be the state that Keigo Uchiha had mastered!

"That's right, this is the Sage Mode of Ryūchi Cave. Facial markings will appear, and the body will inevitably change. The smaller the markings and the less the body changes, the more successful the Sage Mode is!"

The White Snake Sage looked at Keigo Uchiha with excitement.

It was as if she were looking at a priceless treasure.

"Perhaps... you really can accomplish that matter!"

Her amber snake pupils held a trace of yearning!

"You still haven't told this old one how you managed to undo the petrification? Without my help, once a body enters a state of petrification, there is no possibility for an ordinary person to reverse it."

Her snake pupils were filled with curiosity.

This matter was not important to her, nor would she teach it to other contractors, but she was curious.

To break petrification by one's own power.

This was a fundamentally impossible feat.

How on earth did Keigo Uchiha do it?!

"It's not difficult."

Keigo Uchiha chuckled. He grinned, recalling the state he had just been in, and looked up at the White Snake Sage before him, "When you channeled natural energy into my body."

"My body had never been in contact with this power, so it was naturally difficult to control."

"That is why the state of petrification occurred. But during that period of petrification, I quickly mastered Sage Mode, and thus was able to break the petrification. It is not such a difficult thing."

His expression was indifferent.

It was as if he were speaking of the simplest matter imaginable.

But the White Snake Sage was instantly stunned!

"What did you say?! You learned Sage Mode... during the process of petrification?!"

The White Snake Sage's massive serpentine body gradually shrank, returning to the form of that short, elderly woman. She opened her mouth in disbelief, "How is this possible? The process of petrification lasts for only a few short seconds."

"You learned Sage Mode in those few short seconds?"

"This... this is too incredible!"

The process of petrification was too fast, leaving no time for one to react. Moreover, during the process of petrification, anyone would feel despair. Under such fear, how could anyone possibly remain calm enough to learn Sage Mode?

To master natural energy!

Suddenly, the White Snake Sage looked at Keigo Uchiha's calm eyes and realized something.

The youth before her... possessed an absolutely calm, absolutely massive heart.

This allowed him to remain composed in any situation and complete whatever he set his mind to!

"Sage Mode is indeed powerful. The intensity of natural energy is several times stronger than chakra. The power unleashed in this state is even greater, and it possesses the characteristics of Sage Art!"

Keigo Uchiha felt the power within his body.

"Furthermore, the most important thing is that while Sage Mode is difficult to learn, it is a power with extreme adaptability. It can be used in conjunction with other powers, just like Uzumaki Naruto's Kurama Mode combined with Sage Mode in the original story."

"This makes the power even more formidable."

His eyes were extremely calm.

He was analyzing the power he currently commanded.

At the same time, in the state of Sage Mode, he instantly grasped every movement within a radius of five thousand meters.

"White Snake Sage, I need to find a place to test the power I possess now."

Keigo Uchiha spoke softly.

"Of course you may; you already possess the strength to leave this place."

The White Snake Sage smiled, her eyes filled with anticipation.

She, too, wanted to see just what this youth with transcendent talent could achieve.

He kept his eyes tightly shut, his figure moving rapidly!

Yet everything around him was under his control; no protrusions or strange rocks in the cave could harm him in the slightest, allowing him to move as if on flat ground!

This is Sage Mode.

It can perceive everything in the surroundings; all natural forces, plants, and animals in the vicinity become his helpers!

In less than three minutes.

Keigo Uchiha arrived outside the cave, facing a deep mountain forest where dense, ancient trees towered to an absurd height, as if he had arrived on another planet; the oxygen concentration here was also incredibly high.

This was a primeval forest!

There were no traces of any humans!

"Mangekyou Sharingan!"

Following Keigo Uchiha's soft shout, his eyes instantly transformed into scarlet pentagrams, flickering with an eerie light, as if everything would sink into those eyes.

The White Snake Sage appeared beside him, "Mangekyou Sharingan, it has truly been a long time."

"Even after many years, seeing these eyes again still feels astonishing."

Her eyes held shock.

There had been too many shocks today.

Keigo Uchiha learning Sage Mode in a mere half-hour and mastering the Mangekyou Sharingan at the age of thirteen—all of this was like a miracle!

"Have you seen someone with the Mangekyou Sharingan before?"

Keigo Uchiha asked with confusion.

He narrowed his eyes slightly.

It seemed... he had discovered something extraordinary!

"Naturally, a youth from the Uchiha Clan came here once, about several decades ago. One of his eyes was already blind, yet his other eye radiated a soul-shaking ocular power."

The White Snake Sage's eyes were filled with reminiscence.

Even now, she felt a tremor of fear at the memory.

"That fellow... the power he mastered had already transcended the human level, reaching a terrifying peak. If one were to ask what level exists after a human breaks through the peak but remains below the gods, that would likely be the power that fellow possessed."

Below the Six Paths!

The ceiling of the ninja world!

Several decades ago!

Keigo Uchiha reacted instantly, "That was... Uchiha Madara. His eyes were the Eternal Mangekyou Sharingan, even more powerful than my ocular strength; he is the true ceiling of the ninja world!"

In this world, up until now, only Senju Hashirama could suppress that wild man, Uchiha Madara!

If Uzumaki Naruto and Uchiha Sasuke had not received the cheat codes from the Old Man of the Six Paths.

They would not have been Uchiha Madara's match either.

Madara's abilities were too terrifying; whether in temperament, strength, or strategy, he was a supreme genius!

"I never expected Uchiha Madara to have visited the world of Summoning Animals. He must have been searching for the opportunity to activate the Rinnegan."

Having lost one eye meant Uchiha Madara had used Izanami.

He had deceived everyone.

Then he came to the world of Summoning Animals, hoping to find the chance to awaken the Rinnegan. Although he possessed the powers of Asura and Indra, Uchiha Madara had already lost the ocular power of one eye at that time.

This made the awakening of the Rinnegan extremely slow.

Moreover, even awakening the Rinnegan requires time; it cannot be achieved overnight.

Unfortunately, in the end, he still found no effective information.

"Eyes of the Sage!?"

"Rinnegan!?"

The White Snake Sage was stunned. What kind of outrageous words were these? She felt as if she had... stumbled upon something truly incredible, and it made her eyes bloom with astonishing curiosity!

"What does that mean? Why would a member of the Uchiha Clan need to seek the opportunity to awaken the Rinnegan?"

As an ancient creature, her current life held little joy; her only two pleasures were hearing fresh gossip and... seeking the path to becoming a dragon!

This matter made her far too curious.

It was like a hundred claws scratching at her heart!

It was simply unbearable!

Keigo Uchiha chuckled, his eyes lifting slightly. "Madara Uchiha sought the opportunity to awaken the Rinnegan naturally to become more powerful. I can tell you the conditions for awakening the Rinnegan, as well as the secrets of the Mangekyou Sharingan and the Rinnegan."

"But you must agree to one condition of mine."

He smiled faintly, his expression calm and composed.

The White Snake Sage was instantly exasperated. "You fellow, I just allowed you to master Sage Mode, and this is how you treat me? Is that really alright?"

Her eyes opened slightly, radiating a hint of cold light!

As the White Snake Sage, she had never been threatened like this before; this was a provocation against her!

"My apologies, White Snake Sage. My learning of Sage Mode earlier was merely a transaction. Only now can we truly begin to cooperate."

Keigo Uchiha's expression remained indifferent, his scarlet eyes perfectly calm, a smile playing on his lips.

A breeze blew past, making his handsome, peerless profile appear even more dazzling.

Yet, he showed not the slightest intention of backing down.

Facing an ancient, cruel creature like the White Snake Sage, one could never afford to slacken. At the same time, one had to be strong and secure one's own interests, or the White Snake Sage would sooner or later swallow you whole!

The air grew frigid.

It felt as if the spring day had instantly plummeted to sub-zero temperatures!

"Fine."

Suddenly, the White Snake Sage shook her head helplessly, returning to her kindly appearance, though her eyes were filled with frustration and a headache. "You really are a stubborn one."

"I will agree to your condition. This information is simply too tempting. Having lived for so many years, there are few things left that I desire to know, but... that old toad at Mount Myoboku knows this secret!"

"And yet, he never told me back then!"

A trace of indignation flickered across the White Snake Sage's aged face.

Well, well.

Keigo Uchiha was amused; it seemed there was some old history here.

It stood to reason, of course. The Toad Sage had accompanied the Sage of Six Paths as he grew up and had assisted him many times. The two could be considered close friends, so it was only natural that he would know the secrets of the Rinnegan.

"What is your condition?"

The White Snake Sage's aged face was still full of resentment, her anger not yet dissipated. "Once I know, I am going to go and properly annoy that old toad at Mount Myoboku!"

"It isn't good to hold grudges at your age."

Keigo Uchiha said earnestly, "My condition is that I need you to help a friend of mine learn Sage Mode."

"Not the way I learned it, but without any tests, and certainly not treated as roughly as I was. You must channel the surging natural energy into her body directly, and you must guarantee her safety!"

He spoke calmly.

That was right.

When he was practicing Sage Mode earlier, this old hag, the White Snake Sage, had poured energy into him like a waterfall cascading three thousand feet!

If he hadn't possessed Absolute Control, he would have been done for.

"No wonder Orochimaru is wary of your Ryūchi Cave; it isn't without cause."

Damn it.

It was a miracle that Yakushi Kabuto managed to learn Sage Mode in the original story.

At Mount Myoboku, there were at least three who had learned Sage Mode.

Yet, Ryūchi Cave only had one—it was simply absurd.

One had to remember that there were quite a few contractors for Ryūchi Cave: Sasuke Uchiha, Orochimaru, Anko Mitarashi, and Yakushi Kabuto. Yet, only Yakushi Kabuto had managed to learn Sage Mode after constant bodily modifications.

This showed just how dangerous Ryūchi Cave truly was.

"Hehehe, don't be so sensitive. Aren't you alive and well now? I agree."

The White Snake Sage felt a bit awkward.

"So, what is the secret of the Rinnegan? And what kind of connection does it have with the Mangekyou Sharingan?"

The White Snake Sage was full of curiosity and excitement, her eyes wide.

"To speak of the Rinnegan, one must speak of the Sage of Six Paths."

"I know about that!" the White Snake Sage interjected.

Keigo Uchiha cast a faint glance at the White Snake Sage, and she immediately fell silent. Realizing she had spoken out of turn, she hurriedly said, "You continue, I won't interrupt again."

"The Sage of Six Paths had two sons, Asura and Indra."

"Indra obtained the Eyes of the Sage, while Asura obtained the Body of the Sage. Indra awakened the Mangekyou Sharingan, and Asura awakened the Body of the Sage. Because their philosophies differed, the two were locked in endless conflict."

"Thus, even after death, their chakra continued to reincarnate and clash, determined to decide who was superior."

"And to awaken the Rinnegan, one requires the ultimate Body of the Sage from an Asura reincarnate, and the ultimate Eyes of the Sage from an Indra reincarnate!"

"The fusion of these two powers will give birth to All Things in Nature! Awakening the Rinnegan!"

The White Snake Sage was stunned, frozen in place!

She never imagined it would be like this. The Rinnegan... actually evolved from the Mangekyou Sharingan. This completely overturned her understanding, yet when she thought about it carefully, it seemed perfectly logical.

"The fusion of the ultimate powers of the Asura and Indra reincarnates will give birth to All Things in Nature? So... that is the secret to awakening the Rinnegan!"

The White Snake Sage's eyes were filled with excitement.

This was the secret she had been obsessed with for thousands of years, yet never knew.

"So... that's how it is!"

Keigo Uchiha couldn't be bothered to pay further attention to the White Snake Sage. He needed to begin testing his current power. After mastering Sage Mode, both his physical constitution and chakra had been elevated!

He had truly and fully reached the Kage-level!

Although his current combat strength could not yet compare to Senju Hashirama or Uchiha Madara, it was not something an ordinary Kage-level powerhouse could match. However... he still needed to consolidate his strength!

"Storm Armor Technique!"

Keigo Uchiha gave a soft shout.

Instantly, cyan-blue flames erupted across his body, and thunder flickered, making him appear like a god descended from the heavens!

"And... Sage Mode!"

In an instant.

Deep red eyeshadow appeared around his eyes. At the same time, Keigo Uchiha was very curious about what his Mangekyou Sharingan and the snake pupils of Sage Mode would fuse into!

Natural energy surged into Keigo Uchiha's eyes.

The scarlet pentagram rotated slowly as a golden power poured in. As the two merged, a golden snake pupil appeared within the scarlet pentagram!

This was the fusion of Sage Mode and the Mangekyou Sharingan!

Gold and scarlet intertwined.

It added a touch of nobility to this eerie power, and Keigo Uchiha's aura underwent a earth-shattering change. If Keigo Uchiha had been eerie and sinister after activating his Mangekyou Sharingan before, then the current Keigo Uchiha possessed an added air of nobility.

This intertwined temperament.

It gave one the urge to prostrate and worship.

It was as if Keigo Uchiha were the king of this world!

"Not a bad feeling. In this state... even the power of the Mangekyou Sharingan is enhanced!"

Keigo Uchiha's lips curled slightly. Being able to amplify the power of the Mangekyou Sharingan was, in itself, a terrifying thing, especially considering the power of the Mangekyou Sharingan was already terrifying enough.

Yet Sage Mode could make the Mangekyou Sharingan even stronger!

"Sage Art: Storm Release... Light Severing!"

Keigo Uchiha gave a soft shout!

A laser sword instantly appeared in his hand!

The next moment, terrifying cyan-blue thunderous light condensed upon the laser sword, and within this cyan-blue thunder, natural energy fused with it, becoming... even more terrifying!

The light was blinding, as if it were vying with the sun for brilliance!

Keigo Uchiha swung the Sage Art: Storm Release: Light Severing fiercely!

Natural energy, the locking power of the Mangekyou Sharingan, and the power of Storm Release reached their peak in this moment.

This slender beam of light cut through the sky!

It seemed as if the sky itself had been slashed open, but the next moment, the light faded away.

"Such a powerful attack... why didn't it cause any damage?"

The White Snake Sage's voice trembled; this was too terrifying!

The power condensed just now had made even her feel a sense of dread. She dared to guarantee that she would certainly not be able to withstand such a terrifying attack!

Keigo Uchiha's expression remained calm, a faint smile on his lips as if he were expecting something, his gaze fixed on the distance.

"No! It didn't fail to cause damage!"

The White Snake Sage suddenly realized something. "It's that... the power of this attack was too strong. The force of the slash was condensed to the extreme, so... the mountain peak hasn't even changed yet!"

The next moment.

A 'crack' sound echoed through the heavens and earth!

Immediately following this, the hundred-meter-tall mountain in the distance actually... began to move slowly. It was only then that the White Snake Sage noticed a mark on the peak that was smooth to an extreme degree!

"Your attack just now actually... sliced through the entire mountain!"

The mountain tilted!

One-third of the mountain's peak crashed down, shaking the earth and mountains as if it were the end of the world. Countless giant trees toppled, triggering a terrifying chain reaction that caused the surrounding forests to collapse!

The beasts within the forest fled in terror in every direction.

It was a scene akin to the apocalypse!

"An attack like that... is already at the peak of Kage-level. I fear there is no one in the entire ninja world who is your match!"

The White Snake Sage was so shocked that her throat felt parched.

Is this guy... really human?

He is only thirteen years old; why would he possess such terrifying power? Could it be that a powerhouse of extreme terror is truly about to emerge in this world?

"Not bad strength."

Keigo Uchiha chuckled, nodding with satisfaction, "However, I cannot yet be considered a true peak Kage-level."

Although his power had reached that level, Keigo Uchiha had a clear understanding of his own strength.

His chakra and physical body had only just reached the Kage-level.

It was only because his methods of attack were so terrifying, amplified multiple times over, that he had reached his current level.

"Then, White Snake Sage, do not forget the agreement between us."

Keigo Uchiha finished speaking, turned, and his figure vanished from the spot in an instant.

He had clearly used the Reverse Summoning Technique to return to the ninja world.

He was now inside Orochimaru's laboratory.

A small white snake had just vanished from this very spot.

Before leaving, Keigo Uchiha had made full preparations; if he were unable to leave on his own, he could perform the Reverse Summoning Technique to summon the white snake located in Orochimaru's laboratory.

"I have now reached the peak of my current strength, and further improvement will become incredibly difficult."

Keigo Uchiha sighed softly.

He looked at his own hands, "This is a limitation imposed by the body. After all, this body is barely thirteen years old. Therefore, what I must do now is develop my body; the golden age of physical growth is next."

"Many ninjas in the world of Naruto experience rapid improvement during this stage."

"Thus, as I continue my training, my strength will grow ever stronger, and my chakra reserves will increase as well."

He speculated on his current training progress, "Even with normal growth, under the amplification of various powers, my chakra and body will reach the peak of Kage-level!"

"When that time comes, if I can awaken the Eternal Mangekyou Sharingan, I will step into the realm of Super Kage-level powerhouses!"

His voice was filled with certainty as he spoke, enunciating every word: "That is the level of Senju Hashirama and Uchiha Madara back in the day—to become the new God of Shinobi!"

Once he reached that level.

As long as the Otsutsuki did not appear.

And Uchiha Madara was not resurrected.

Then there would be no power in the entire ninja world capable of restraining him. Changing the entire ninja world would be a matter of a single word from him!

Have you ever seen a Susanoo-clad Sage wipe out four nations single-handedly?!

That is his level!

"Oh? Keigo, you've returned?"

At this moment, the laboratory door suddenly opened. Orochimaru looked stunned for a moment, then looked at Keigo Uchiha and spoke in a serious tone, "You need to return to the Uchiha Clan; it seems something has happened within your Uchiha Clan!"
