Konoha: Starting with Sage Mode

Of course, in Kirito's eyes, this female medical ninja's medical ninjutsu ability was far inferior to his sister Tsunade, at most comparable to some elite medical ninjas in Konoha Hospital.

However, in Kumogakure, a ninja village where the medical ninja system has only just been established, Casalan can be considered one of the top medical ninjas in Kumogakure. He is also quite talented in pharmacology and pharmaceuticals. Currently, he serves as the head of the pharmacy department in the hospital, responsible for the important work of drug quality testing and daily receipt and dispatch.

At the same time, Casalan is also a skilled ninja with the strength of a special Jonin.

Unlike the Samui that Kirito remembers, Casalan is not an ice queen, but a cheerful and enthusiastic beauty who is currently single and is hailed by many as the village beauty of Kumogakure, and is secretly admired by many.

It's worth mentioning that Kirito, who is using the medical ninja named Saka, is also a secret admirer of Casalan, and quite fervently so, secretly gathering all sorts of information about Casalan.

Kirito's peeping at Casalan was quickly noticed by Casalan, who was very sensitive to the gazes of others. She turned her head and saw the medical ninja that Kirito was controlling. She only gave Kirito a gentle smile before continuing to concentrate on her work.

As a renowned beauty in Kumogakure, she was already used to being secretly admired.

But she felt a little strange. Saka's gaze towards her today was different. It lacked the familiar, adoring look he usually gave her; it was just a very indifferent look.

Casalan found this somewhat strange, but didn't take it to heart.

She was too busy to pay attention to a medical ninja with only average medical ninjutsu skills.

"If it were her, she would probably know some information about Brubi's medication."

Kirito recalled the information about Casalan and thought to himself.

To avoid attracting the attention of the Cloud Village, Kirito patiently waited until Casaran finished get off work as usual, then manipulated Casaran back to his home, and then re-exposed his soul.

"You're lucky. If we killed you, it would definitely attract the attention of the Hidden Cloud Village."

Kirito looked at Kasa, who had collapsed to the ground, and murmured something. Then he used his chakra to create a thin needle and pierced it into Kasa's brain.

Ninja Technique: Hidden in the Sand and Exercise Your Brain.

This ninjutsu that can seal his memories was learned from Akasuna's memories. This son of Chiyo naturally learned a lot of skills from his uncle Ebizo during his growth. He easily obtained precious ninjutsu like the Sandstorm Mind Control technique.

But now Kirito is the one who benefits.

After successfully sealing Kasa's memories, Kirito began to search for her by following the aura of Kasaran's soul.

This beautiful ninja has a very colorful nightlife. Every night, people invite her out for drinks. She is a heavy drinker, and a very heavy one at that. She is a well-known female heavy drinker in Kumogakure.

Tonight, the beautiful ninja also had a hearty drink, and was then safely escorted home by a familiar childhood friend, a male ninja.

"Coward! I pretended to be drunk, and you still didn't dare to lay a hand on me."

After the male ninja left, Casalan, who had been drunk, opened his eyes and thought with some disappointment.

"Then let me do something slightly to you."

But the next moment, her expression froze, and a look of horror appeared in her eyes, because she found that her body suddenly could not move. As a strange voice appeared in her mind, she lost consciousness, and her open eyes lost their light.

A short while later, Casalan's eyes regained their light.

But at this moment, Casaran's body has been temporarily taken over by Kirito.

As for Casalan's soul, he temporarily sealed it in a corner of his body using a simple soul-sealing technique he developed from the Corpse Demon Sealing technique.

"Let me see your memories."

Kirito manipulated Casalan's body to extract Casalan's soul from his own body and smiled slightly.

Spiritualization Technique: Soul Search!

Soon, Kirito finished reading Casalan's memories and learned a lot about Brubi and the secrets of Kumogakure.

For example, although Brubi has not yet developed a serious mental illness and needs to take psychiatric medication to stabilize his mental state, he needs to take some healing medication to promote physical recovery because of his usual tailed beast transformation training.

Jinchuriki generally have strong physical recovery abilities, but if they cannot become perfect Jinchuriki, once they enter Tailed Beast form, the Tailed Beast's chakra will still severely erode their bodies, causing serious damage that they cannot recover normally in a short period of time.

Casalan was the one who prepared and delivered the medicine to Brubi.

For example, the Hidden Cloud Village is secretly developing a special drug that can enhance physical strength.

For example, the Hidden Cloud Village is planning to develop a secret weapon called the Chakra Cannon.

and many more.

"The healing medicine is delivered once a month, and four weeks have passed since the last delivery. That means I don't have much time left to make medicine that can temporarily control Brubi."

Kirito manipulated Casalan's body to stand up and murmured.

Afterwards, he took a shower to wash away the smell of alcohol, changed into a new set of clothes, and then quickly headed to the hospital.

Time was of the essence; he needed to quickly prepare a powerful anesthetic so that Burubi, the Eight-Tails Jinchuriki, would be instantly immobilized after taking it.

However, not long after he stepped out the door, three Cloud Village Anbu ninjas suddenly appeared.

"Is something the matter so late?"

Kirito smiled calmly upon seeing the three suddenly appearing Cloud Village Anbu ninjas, trying his best to portray the Casalan from his memories.

The three Cloud Village Anbu ninjas clearly did not doubt Kirito's current identity in Casalan. The leader of the Anbu ninjas stepped forward and explained, "Casara Jonin, the Raikage requests your presence."

Upon hearing that the Third Raikage was looking for Casalan, Kirito immediately entered the Memory Library and quickly searched through Casalan's memories, looking for all the information about the Third Raikage in order to deduce why the Third Raikage was calling Casalan over.

He concluded that the Third Raikage must have asked Casalan about the special drug that could enhance physical strength.

Kirito learned from Casalan's memories that this special drug was originally invented by Casalan and other medical ninjas at the request of the Third Raikage in order to further improve his physical strength. However, the research and development process has been fraught with difficulties, and no phased research results have been achieved yet.

"I understand, please lead the way."

A second later, Kirito exited the Memory Library and nodded to the ANBU ninja in front of him.

A few minutes later, in the Raikage Building, in the Raikage's office, Kirito saw the Third Raikage again. This Raikage was actually lifting two huge barbells to strengthen his arms.

"Lord Raikage."

Upon seeing the Third Raikage, Kirito immediately imitated the attitude and actions of Casalan when he met the Third Raikage, kneeling on one knee with an expression of admiration, and respectfully addressed the Third Raikage.

When the Third Raikage saw the Casalan controlled by Kirito, he frowned slightly. His intuition told him that there was something strange about the Casalan in front of him, but upon closer inspection, he could not find anything wrong.

Then, he looked at his beautiful secretary, Elui, and saw her shake her head slightly, which finally dispelled his doubts.

His beautiful secretary not only has excellent office skills, but is also an excellent sensory ninja. Since she was unable to find anything unusual about Casalan, the Casalan in front of her should not be an imposter.

"Don't be so formal, Casalan. I'm really sorry to have called you so late, but my old problem with the scar on my chest has flared up again, and I'm feeling a bit uncomfortable. I need you to take a look at it for me."

After dispelling his doubts, he spoke to Kirito in a kind and gentle manner.

He quite liked the talented and beautiful female subordinate in front of him. When the scar on his chest flared up again, he immediately thought of her and wanted her to treat him personally.

Kirito was overjoyed when he learned why the Third Raikage had summoned Casaran. He hadn't expected things to take such an unexpected turn, and he thought he might be able to use this opportunity to obtain tissue cells from the Third Raikage.

The next moment, he put on a stern face and reprimanded the Third Raikage without any politeness: "Lord Raikage, please put down the barbell immediately. You will only aggravate your injuries by doing so."

When facing patients, Casalan immediately transforms into an icy beauty, treating them with meticulous care.

Kirito's acting skills are undoubtedly outstanding, thanks to his hard work in playing three different roles.

Seeing this familiar change in Casalan's attitude, the Third Raikage's last remaining doubts finally disappeared, and he laughed heartily, "Hahaha~ Casalan, don't worry, it's just a minor injury, nothing serious."

However, despite saying that, under Kirito's cold gaze, he still obeyed the doctor's instructions, obediently put down the two barbells in his hands, and then lay down on the bed in the office for Kirito to examine him.

By robbing medical ninjas from other ninja villages, Kumogakure has also established a relatively complete lineage of medical ninjutsu, including techniques such as using chakra to detect internal bodily conditions, Healing Palm Technique, and chakra scalpels.

Kirito himself is an excellent medical ninja, and he had no problem examining and treating the Third Raikage.

He quickly discovered the reason for the Third Raikage's discomfort and replied, "Lord Raikage, please do not overtrain recently. The hidden injury in your left chest is worsening, and I need to perform a minor surgery to remove the necrotic flesh inside."

The Third Raikage had great trust in Casalan's medical ninjutsu, and Kirito's recent use of medical ninjutsu to examine Casalan's body did indeed demonstrate an extremely high level of medical skill.

Hearing Kirito's words, he replied without hesitation, "Then come on then. No need for anesthesia, but you'll have a hard time cutting open my body, hahaha~"

"This guy's body is indeed extraordinary. The density of the muscles on the surface of his body is incredibly high, making him practically a body of steel. It's estimated that even ninja tools made of chakra metal and ordinary ninjutsu would have difficulty damaging his body."

Upon hearing this, Kirito was filled with astonishment.

Although he had long known that the Third Raikage's physical strength was extraordinary, he was only truly surprised to learn how incredibly strong the human body could be trained after he had actually understood its true strength.

Unsurprisingly, the Third Raikage's physical strength is the strongest among humans in the world today.

"I apologize, Lord Raikage."

Kirito said seriously, and then used his chakra scalpel.

At the same time, he used his other hand to inject chakra into the Third Raikage's body to probe the Third Raikage's internal condition again, and then used a chakra scalpel to cut into the Third Raikage's body.

Although the Third Raikage's body is incredibly hard, there are always gaps in human muscles. If you can accurately locate these gaps, you can cut open the Third Raikage's body like a skilled butcher dissecting an ox.

"Kasaran's medical ninjutsu skills seem to have made a new breakthrough recently. He was able to cut open the Raikage's body so easily with a chakra scalpel."

Ellie, who was acting as a guard, watched Kirito easily slice through the Third Raikage's body and thought in surprise.

Her secretary, who was almost inseparable from the Third Raikage, knew best just how abnormal the Third Raikage's body was. Even if a high-quality ninja tool made of chakra metal was infused with chakra to enhance its sharpness, it would not be able to harm the Third Raikage's body.

But how could she not be surprised that Casalan could so easily cut open the Third Raikage's body with a chakra scalpel?

Compared to Ellie, the Third Raikage was undoubtedly more aware of how skillful Kirito's method of cutting open his body with medical ninjutsu was, and exclaimed, "Well done, Casaran. Your medical ninjutsu has improved a lot recently, and with your current understanding of human muscles, your swordsmanship will definitely improve greatly in the future."

"Please don't speak, Lord Raikage. You're distracting me."

Kirito responded coldly upon hearing the Third Raikage's praise.

As he spoke, he deliberately and accidentally used a chakra scalpel to gently prick the more vulnerable muscles inside the Third Raikage's body, causing the Third Raikage to wisely shut his mouth.

Before long, Kirito successfully located the necrotic tissue inside the Third Raikage's body, perfectly cut and separated it from the Third Raikage's body, and then used Healing Palm Technique to treat the Third Raikage's wounds with meticulous care.

"Phew, it's finished. Raikage-sama, how does it look now?"

Kirito wiped the sweat from his forehead with his arm and smiled as he spoke to the Third Raikage.

He had exhausted a great deal of mental energy in order to perfectly sever the Third Raikage's body, and was now somewhat mentally fatigued.

"It feels great, the pain is gone."

The Third Raikage patted his freshly treated wound and exclaimed in admiration.

Seeing this, Kirito wanted to persuade the other party not to do this, but a large hand reached out to him like lightning, making the hairs on his body stand on end.

The Third Raikage's expression suddenly turned cold. He gripped Kirito's neck, which was now occupied by Casalan, and lifted him up, saying menacingly, "Tell me, who are you? Where is the real Casalan?"

Chapter 155: Madara Uchiha Awakens Again

"What, what are you saying, Lord Raikage?"

Kirito listened to the Third Raikage's words and said with a pained expression.

It's impossible for him to admit it, at least not under the current circumstances.
