Naruto: I've already fought against all five Kage, and the system only just arrived.

Miyata Keika really thought highly of Sōsuke, and gave him earnest advice before parting.

Yu Yi Xuan Yue expressed her gratitude.

Watching Miyata Keika's departing figure, he suddenly smiled to himself:

"Tsunade's disciple? What an interesting suggestion. I wonder how Tsunade will react when she discovers the truth after it's done."

"Wait a minute. If we're really discovered, it seems like I'm at a huge disadvantage, while Tsunade is the one who benefits the most."

For someone as dignified as Yu Yi Xuan Yue to become Tsunade's disciple is a huge loss of face for her.

Of course, Yu Yi Xuan Yue wouldn't bother to become Tsunade's disciple.

He doesn't need to waste his time on this.

"Seven days should be about right."

"If all else fails, we can always sneak in without permission."

Yu Yi Xuan Yue touched her chest.

During his time studying in Konoha, he has gained complete mastery of extracting Sage Chakra.

The reason for applying for a research lab was to use the sophisticated machines inside to thoroughly explore the mysteries of Sage Chakra.

He's not some old-fashioned person who would choose to stick to tradition when there are more efficient methods available.

Efficiency is the top priority in everything.

If one could gain the opportunity to acquire one's own unique immortal techniques through this, that would be even better.

I still vividly remember the image of Hashirama Senju stepping on a giant Buddha in Sage Mode back then.

In the afternoon, following instructions, Yu Yi Xuan Yue arrived at the Konoha Hospital Research Building.

Aside from the Root's secret laboratory and some top-level classified research projects, most of Konoha's research projects are openly located in this building.

Therefore, the defense here is quite tight.

Yu Yi Xuan Yue has undergone three tests along the way.

Thanks to the secret technique of Yanxie, which can be described as a perfect transformation technique, Yu Yi Xuan Yue arrived at the A-level research lab that was temporarily hers as expected.

Watching the ninja in charge of the area form hand seals and unlock the door, he didn't immediately enter. Instead, he met the eyes of the Konoha ninja who turned around, and as his pupils subtly moved like hand seals, he politely thanked him:

"sorry to bother you."

The Konoha ninjas didn't find anything, they just waved for Hagoromo Gengetsu to go inside.

Yu Yi Xuan Yue nodded and strode inside.

Thanks to the eye imprint technique offered by Ari, after making eye contact with the Konoha ninja at close range for a short time under certain conditions, and secretly imprinting the information in their minds, everything here has been opened to him, and secrets are no longer secrets.

"Now, it's time to get down to business."

The research lab door closed, and Yu Yixuanyue looked at the various high-tech instruments inside, including those for biology, cultivation, scanning, and computational analysis, and a smile appeared on her lips.

It has to be said that the technology in the ninja world is ridiculously out of touch.

In most places, ordinary people still live the life of the feudal era.

However, here, some high-tech instruments are not only no less advanced than those of the previous generation, but even surpass them in the field of biology.

This is the foundation of the largest village in the ninja world.

If it were the Feathered Clan, let alone whether they would have sufficient funds to build a research lab like the one before us.

Even if they did have access, those high-tech instruments wouldn't be something they could buy through their own channels.

Konoha itself also has a science department.

The ninjas weren't stupid; they wouldn't spread this extremely important scientific research tool around.

Science and technology are primary productive forces.

This is also one of the reasons why Yu Yi Xuan Yue chose to come to Konoha.

Without further delay, Yu Yi Xuan Yue took off her top, prepared herself, and said:

"The first step is to extract the Sage Chakra without missing a single drop."

Chapter 84 Completely Resolving Hidden Health Issues

Because of the forbidden technique, Breath of Eternal Sleep, the Sage Chakra left behind by Hashirama Senju has resided within his vibrant body for over fifty years, becoming like a deeply ingrained infection that ordinary medical ninjutsu cannot eradicate.

Fortunately, Hagoromo Gengetsu had a great talent for medical ninjutsu, and with his comprehensive understanding, he developed a new technique specifically for this purpose.

"The method of extracting immortal techniques!"

Yu Yi Xuan Yue placed her right hand on her chest, and green chakra, like bubbles, instantly appeared, deeply reflecting into the depths of her chest.

Visibly, strand after strand of Sage Chakra was drawn from Yuu Gengetsu's flesh, bones, and even cells without causing any damage. Then, it was enveloped by green chakra bubbles, without leaking out at all.

The Sage Art Extraction Technique is a method developed by Hagoromo Gengetsu, based on the Fine Ailment Extraction Technique and combining it with other medical ninjutsu and his own physical condition. It is specifically designed for extracting and storing Sage Chakra that does not belong to him. It represents his achievements in the medical field over this period, working from both Shennong and Konoha perspectives.

Everything went as planned.

Yu Yi Xuan Yue sensed that the Sage Chakra within her body was rapidly and silently decreasing.

Finally, look at the small cluster of special chakra gathered together within the green chakra bubble, constantly consuming green chakra without suffering any loss itself.

Yu Yi Xuan Yue knew that this was Sage Chakra.

In the current ninja world, apart from the half-baked Jiraiya who could barely manage to produce something when forced into a corner, he is truly unique.

For example, Jugo and Orochimaru developed a cursed seal based on their special constitutions, but these were merely crude applications of natural energy and could not be called Sage Arts at all.

Looking at the rare Sage Chakra that had been temporarily preserved in her hand by the Sage Extraction Technique, Hagoromo Gengetsu first used a medical ninjutsu to heal the minor injuries caused by the residual Sage Chakra in her body.

The moment the last ruptured blood vessel was repaired to its original state.

Pfft!Pfft!

My heart is beating strongly.

It was as if the machine had been completely renovated.

Yu Yi Xuan Yue could clearly feel that the blood maintaining normal bodily functions was flowing smoothly throughout her body, and all the cells in her body were cheering with joy.

My body has since fully recovered to its peak condition.

Feeling the powerful energy within her body being released without any hindrance, Yu Yi Xuan Yue smiled, having successfully completed her first small goal after living her second life.

After that, he had already made progress on the matter of completing his soul and truly achieving a perfect state.

There's no need to rush now; let's deal with the Sage Chakra we have first.

Yu Yi Xuan Yue took out a special container that could store chakra from the research lab and placed the Sage Chakra inside.

In the following period, he transformed into a scientist like Orochimaru, using various high-tech instruments in the research lab to scan, analyze, and experiment with Sage Chakra.

Didi didi.

The sound of the machines running echoed continuously.

Experiment reports were printed out one after another.

"As stated in the original work, Sage Chakra is formed by the perfect fusion of ordinary chakra, which is a mixture of physical and spiritual energy, and natural energy. The three types of chakra must be balanced, each accounting for one-third. Too much natural energy will devour the body, while too little will prevent the activation of Sage Mode."

"Yes, the internal proportions of this Sage Chakra are indeed as described."

"But knowing this is one thing, the real key lies in how ordinary chakra can be perfectly integrated with natural energy. This seems to require a special arrangement and combination; simply dividing it into three won't work."

"Furthermore, the human body is not a chip; it's impossible to precisely calculate the amount of natural energy absorbed. Let's conduct multiple simulation experiments."

"Troublesome indeed. No wonder so few people have truly mastered immortal arts over the past thousand years."

"The absorption of natural energy is also a major challenge. It seems to favor creatures like toads, snakes, and slugs. The immortal arts of the three sacred lands all require humans to actively adapt to them. Immortal arts based on humans have yet to emerge."

"Uh, I need experimental materials. I'll just use my own slices then."

"If we go it this way, there's some possibility."

"."

After that, Yu Yi Xuan Yue shut herself in and devoted herself to the novel field of immortal arts.

Even after seven days, he still entered without notice, easily breaking through the barriers using information obtained from the Konoha ninjas, and sneaking into the research lab to continue his great research.

Everything is fine in the research lab.

Meanwhile, outside, the turmoil in the ninja world intensified.

Outside Konoha Village, in a remote area.

Tsunade put on her Hokage hat and said to the two Konoha advisors, Mitokado Homura and Utatane Koharu, who had come to see her off, "I'm entrusting Konoha to you two for the time being."

Although she had disagreements with these two old men on many things, Tsunade, who was about to embark on a long journey, could only entrust village affairs to these two experienced and prestigious elders.

As for the other Konoha advisor...

If she could, Tsunade would wish for him to live in that dark underground base forever.

"Fifth Generation Leader, rest assured, we will keep a close eye on the village during this period," Mitokado Homura nodded.

"but."

He looked at Tsunade's side with a worried expression.

It's one thing that Silent is always by my side.

Naruto, with his hands behind his head, looking left and right with great excitement, also looked like he was about to embark on a long journey.

"Is it appropriate to bring Naruto Uzumaki along?" Mitokado Homura asked, frowning.

Since it concerned the Nine-Tails Jinchuriki, who was extremely important to the village, he had to ask one more question.

"Huh? Grandpa, do you know me?" Naruto, who didn't recognize the two old men in front of him, looked up and asked with great confusion.

Mitomon Yan twitched his lips but didn't say anything more.

Tsunade patted Naruto on the shoulder and said firmly, "I will ensure Naruto's safety."
