Chapter 311: Perfect Sage Mode

As spring came and autumn went, two cold winters passed in the blink of an eye. Besides practicing day and night in the Senjutsu holy land, Ryuchi Cave, Yu seldom returned to Konoha to relax and entertain with Yugao and Kurenai.

A day in the mountains is a thousand years in the world. In the timeless space of Ryuchi Cave, Yu didn't feel the passage of time while training.

Yu also learned by chance one day about Shisui throwing himself into the Naka River to commit suicide. Although he had verbally declared the end of their friendship, knowing that his only friend in Konoha, Shisui, chose the same path as before—sacrificing himself willingly for the sake of Konoha and his clan to delay the Uchiha Clan's coup—ultimately ending in tragedy, Yu couldn't help but remain silent for a long time, sighing in his heart.

"Sage Mode, Activate!"

In the still overcast Ryuchi Cave, standing amidst an endless forest of white stalactites, Yu, who was meditating with his eyes closed, suddenly clasped his hands together in front of him and let out a loud shout. A vast amount of Senjutsu Chakra erupted within him!

An invisible aura emanated from him as the massive Senjutsu Chakra quickly took shape inside him. However, unlike before, his face did not show any Sage markings; it was as if nothing had happened. Only his amber-clear pupils transformed into the unique slit pupils of Ryuchi Cave's Sage Mode, giving him a fierce and eerie gaze that was hard to meet directly.

Moreover, a magnificent white divine robe appeared out of nowhere on Yu's body, adorned with countless mysterious and obscure Senjutsu runes. His originally tousled white hair, which covered his forehead, stood up and swept back, transforming into a neat and slicked-back hairstyle.

The Sage Art divine robe, white with black edges, worn by Yu made him look like a deity descending to the mortal world at first glance. At a second glance, he seemed like a mortal ascending to divinity. His demeanor and aura underwent a drastic change, with the once handsome and refreshing youth seemingly evolving into a godly figure, commanding respect and awe as if ruling the world.

"Is it done? Perfect Sage Mode..."

"But this appearance, isn't it a bit too cool..."

Yu, sporting a slicked-back white hairstyle and the white divine robe that had inexplicably appeared on him, murmured to himself in astonishment.

Back in his past life watching Naruto, he had always wondered why protagonists like Naruto, in Sage Mode, Six Paths Sage Mode, or Kurama Mode, would always manifest a new outfit out of thin air. Never did he imagine experiencing such a thing himself one day.

"Yu... Yu-sama, your appearance..."

At this moment, witnessing the dramatic transformation in Yu's appearance after entering Perfect Sage Mode, Haku and Kimimaro, who were diligently training nearby, had long stopped their actions, speechless with astonishment.

It's worth noting that based on the features shown on Naruto Uzumaki, Yakushi Kabuto, and Senju Hashirama after they entered Sage Mode in the anime, it can be observed that the Sage markings from Mount Myoboku are orange, from Ryuchi Cave are purple, and from Shikkotsu Forest are red.

However, the higher the completion of Sage Mode, the less prominent the facial markings and animal features associated with the Sage markings, which reflects the ninja's mastery over Senjutsu Chakra.

Now that Yu has entered what is called Perfect Sage Mode, there are almost no Sage markings or snake-like features visible on him, which sufficiently proves his high level of control over Senjutsu Chakra in this state.

"Sage Art: Water Dragon Biting Explosion!!"

Knowing that he might not sustain this perfect Sage Mode state for long, Yu disregarded the surprised Haku and Kimimaro beside him. He swiftly formed seals with his hands in front of him, intending to test the power of Perfect Sage Mode.

Taking a deep breath, he mobilized the massive Senjutsu Chakra within him. In an instant, behind Yu, it seemed as if an entire sea had appeared, and an endless water dragon directly formed into a roaring water dragon nearly breaking through a hundred meters in size!

"Roar!!"

Accompanied by the earth-shaking roar of the water dragon echoing throughout Ryuchi Cave, the terrifying power, akin to unleashing the entire ocean, completely submerged the vast forest of white stalactites before Yu's eyes, destroying everything in its path.

"Such exaggeration..."

"At least the power of Ninjutsu has been amplified by more than three times..."

Seeing the devastating power he could unleash with S-rank Water Release Ninjutsu in Perfect Sage Mode, Yu couldn't help but feel a bit stunned and dazed.

"Dragon Fang!!"

Intending to test the enhancement of Taijutsu again, Yu took a step and almost instantly appeared dozens of meters away at the edge of the white stalactite forest, launching a full-force whip kick!

A giant dragon-shaped shockwave formed into a raging Air Cannon in an instant, roaring through the air. It immediately shattered dozens of towering stalactites, creating a powerful hurricane in the vast and boundless Ryuchi Cave.

Rumble...

Dozens of fallen stalactites kicked up clouds of dust. Yu stared down at his body in disbelief. This level of power... Taijutsu seemed to have been amplified by at least ten times, comparable to the enhancement brought by Shunko.

What's even more terrifying is that Yu's Perfect Sage Mode can be activated instantly and lasts until his Senjutsu Chakra is depleted. In other words, in terms of endurance, it can easily outlast Shunko and the Eight Inner Gates technique by a long shot.

Yu chose not to train in the Eight Inner Gates technique for two reasons: first, he didn't have access to the training method; second, the technique inflicts severe damage on the body, effectively a forbidden jutsu that drains life force.

Although Sage Mode cannot amplify Taijutsu to the extent of surpassing the Five Kage by tens of times in a short period, like the Eight Inner Gates Formation, its advantages lie in safety and endurance. It provides comprehensive enhancements not only to Ninjutsu, Taijutsu, and Genjutsu but also to sensing abilities and even recovery capabilities.

Furthermore, using Senjutsu Chakra differs from using regular Chakra. While fighting with regular Chakra leads to increasing fatigue, fighting with Senjutsu Chakra makes one more spirited. It's like having a completely flawless advantage.

"But I can only maintain it for ten seconds..."

Just after releasing a Ninjutsu and unleashing a Taijutsu move, Yu felt a tremor in his body, and the Senjutsu Chakra that had achieved perfect balance inside him dissipated.

The magnificent Sage divine robe on him gradually disappeared, and his slicked-back white hairstyle fell back into its original tousled state, returning his body to its ordinary condition.

"Looks like there's still a long way to go to fully achieve Perfect Sage Mode..."

Having just completed Perfect Sage Mode, which could only be sustained for a short ten seconds, Yu couldn't believe he had become a 'ten-second man' himself one day, a wry smile appearing on his face.

"You brat! You've destroyed our Ryuchi Cave again!!"

An enraged voice erupted from behind him, causing Yu to stiffen. He turned around to see Tagitsuhime and Tagorihime, the two snake Sages of Ryuchi Cave, approaching with fury.

"I'm sorry, Tagitsuhime-sama, Tagorihime-sama!!"

"I'll come back next time to apologize... I have urgent matters to attend to, so I'll take my leave!"

During his two years of training in Ryuchi Cave, Yu had already become acquainted with Tagitsuhime and Tagorihime, the Elders of Ryuchi Cave.

Realizing his fault in inadvertently destroying Ryuchi Cave again, Yu took a step back and quickly grabbed Haku and Kimimaro nearby, stepping into the portal of the alternate space opened by Kaio to leave the area.

"This brat..."

"I wonder if allowing him to cultivate Senjutsu in Ryuchi Cave under the White Snake Sage's permission was right or wrong..."

After watching Yu disappear with White and the others, Tagitsuhime Sage, standing still, murmured with a hint of distraction, "But this kid has actually cultivated Perfect Sage Mode, something no one has achieved in Ryuchi Cave's history..."

"If the White Snake Sage knew about this, she would surely be greatly shocked..."
