Naruto: Immortal Spirit

"Beiliuhu, have you ever thought that this world may have never belonged to us?"

Deep in the laboratory, Bei Liuhu had a bit of amazement in his eyes as he slowly walked past each piece of equipment.

This was probably a feat that could only be accomplished by a country whose finances were dominated by researchers—it only had basic instruments, and it was already the most perfect laboratory he had ever seen.

When he thought that he was about to have the right to use these devices, his heart felt a little hot. Hearing Kato Oo's voice, he couldn't help but look away and thought for a moment.

"This world? It probably doesn't belong to anyone, right?"

Bei Liuhu was a little confused for no reason. He probably had never considered such a problem before.

Smiling softly, Kato Ou didn't seem to expect anything, "This is what I told you, 'the number one research in the ninja world'..." A huge scroll appeared in the laboratory.

Kato Ou compiled Kabuto's experimental records, followed the hints of truth revealed in the data, and recorded some of his conjectures one by one.

"It seems to be telling me that princes, generals and ministers all have their own kind... and ants will always be ants..." Kato Ou gently stroked the scroll, and there was a momentary absence in Kato Oo's eyes, with a vague look of reminiscence.

"Oh?" Looking at Kato Oo's expression, Bei Liuhu also frowned slightly, and slowly opened the scroll with confusion in his eyes.

The laboratory was quiet. Kato Ou didn't say anything more. He glanced at Beiruhu who was immersed in the scroll, then turned and left.

"Xu! You finally came out!"

As soon as he walked out of the door, he saw Lin, who was sitting on the ground with her head propped up in boredom, with a bit of anxiety in her eyes, as if she had been waiting for him for a long time. When she saw Kato Oo, she jumped up from the ground.

"Lin, are you skipping school again?"

"When did Xujun become so bad!"

Lin was stunned for a second, couldn't help but pursed her lips, and looked at Kato Oo angrily, as if she thought of something again, and her expression changed again in the blink of an eye.

"Ou-kun! Come with me! Guren doesn't know what happened, and suddenly passed out. The medical ninjas in the hospital are helpless!"

Lin dragged Kato Oo and was about to take him away. A trace of doubt flashed in Kato Oo's eyes, but after looking at Lin's anxious expression, he did not immediately ask questions. He stepped lightly, picked up the back of Lin's clothes, and walked away. Disappeared in place.

"Didn't Kabuto come over?"

The scenery in her ears receded rapidly, Lin seemed to breathe a sigh of relief, and Kato Oo spoke softly.

"Kabuto can't see what the problem is..."

If it was an ordinary injury, Kabuto shouldn't be helpless according to Kabuto's current level of medical ninjutsu. Kato O kept his feet on the ground, and after thinking about it, he couldn't help but show a look of interest.

"I understand……"

The hospital in Kusanagi Village is not too big, just a small building. There are many ordinary medical staff, but there are very few who can be called medical ninjas. After all, it is difficult to learn medical ninjutsu and control chakra. The ability requirements are very high. Without talent in this area, it will be difficult to achieve anything.

Kato Oo took Lin into the hospital.

Although the hospital is not big, there are quite a few people coming and going. The Country of Grass is only a small country and does not have a 'government agency' equivalent to the big names of the five major countries. However, for this reason, the Kusanagi Village is not only a violent place in the Country of Grass. The organization is also the governing body of the Country of Grass.

Over the years, under the governance of Nono U and Zabuza, Kusanagi Village has gradually become the political and economic center of the entire Kingdom of Grass. A large number of civilians have poured into the Kingdom of Grass, which has brought tax revenue to the Village of Kusanagi and also increased its income. Due to the demand for infrastructure, such a small hospital is already overcrowded.

"Here! Here!"

Lin and Kato Oo went up to the second floor. As soon as they entered the ward, Kato Oo's eyes moved slightly and his eyes couldn't help but fall on the trembling girl on the hospital bed.

"Master! You are here..."

"I..., I can't see what the problem is..."

Kabuto suddenly looked up when he heard Lin's voice, and when he saw Kato Oo, there was a look of relief in his eyes, but then he showed a bit of frustration again.

"It's okay Kabuto, this is not an ordinary injury..."

Kato O's eyes flashed slightly, and the other doctors and nurses in the ward filed out, leaving only Lin and Kabuto.

"I probably understand what's going on..."

Kato Oo slowly walked to the side of the girl named Guren. The twelve or thirteen year old girl was covered in sweat, her body was trembling, and her brows were furrowed, as if she was enduring some kind of deep pain...

After looking at it for a while, under the slightly widened eyes of Lin and Kabuto, Katoo slowly untied half of Guren's clothes, exposing his shoulders to the air...

"This is……"

Three black magatama slowly lay on the girl's shoulders, faintly emitting red light. Kabuto instantly understood that the girl's pain came from this...

"The curse seal... seems to have a familiar aura..."

"Xu, what's wrong with Honglian?"

Lin still had doubts in her eyes, and she didn't understand the current situation...

"Lin, when did this girl come to the Country of Grass?" Kato Ou asked instead of answering Lin's question.

"About two years ago...not long after Ou-kun left, he was a war orphan rescued by Zabuza-sama..."

"She is also a rare crystal escape blood successor limited ninja..."

"Xu..., is there anything wrong with her?"

In the past two years, Lin and Guren have become very close. She likes this child very much, but the current situation makes her vaguely aware of something, and she looks at Kato Ou in disbelief.

"Don't worry..., it's probably just a little joke between my teacher Orochimaru and me..."

Kato Ou smiled softly, comforted Lin, and gently pressed one hand on the curse seal. Chakra slowly poured in, as if he was feeling something...

"The chakra in the curse seal fluctuates greatly... The originally stable curse seal has become extremely unstable. The overflowing alien chakra has caused this girl's pain..."

A smile flashed slightly in his eyes, and Kato Ou seemed to understand something. Apart from Orochimaru, he was the only one who understood the secrets of the Fuzhi Reincarnation technique best...

"It seems that Mr. Orochimaru has reached a critical moment..."

A dark rune chain appeared in his hand, forming a ring-like seal in an instant, completely blocking the energy emanating from the curse seal.

The red light slowly faded away, and the girl's body gradually became quieter, her breathing gradually became steady, and she fell into a deep sleep...

Seeing Guren's condition getting better, both Lin and Kabuto breathed a sigh of relief, and a smile appeared on Kato O's lips.

Rubbing Lin's head with one hand, he looked at Kabuto: "Kabuto, are you interested in meeting my teacher, Orochimaru, one of the three ninjas..."

"Master's teacher? Is it really okay?"

"Maybe, he will like you very much..."
