Dark Medical Ninjutsu

Today, having nothing to do, Yichen went to the Iwagakure Hospital.

The Iwagakure Hospital has been quite lively lately because Yichen has invited a renowned medical expert from the Ninja World: Shinno.

Shinno Yichen's invitation and accepted Iwagakure Uzumaki Karin, Genin had just graduated from Iwagakure, and Sakura Haruno, who was still in the Ninja Academy, as his disciples.

When the two girls became his disciples, Yichen personally made an appearance and directly informed the Ninja World that they were also his Yichen.

This left those unaware of the identity of the leader of Shinno Leader of Sky Ninja Village completely bewildered.

They couldn't understand why Yichen was making such a fuss over something as simple as a Medical Ninja taking on a disciple.

Yichen arrived at the hospital and first met with Ōnoki and Sokai, who were responsible for monitoring Shinno.

Shinno was, after all, a research freak like Zero Tail, Yichen wasn't comfortable letting him roam freely in Iwagakure.

Only by having Ōnoki and Mangekyō Sharingan, who possesses the Sokai Sharingan, keep an eye on him can Yichen feel at ease.

Even if Shinno Iwagakure releases the Zero Tail, the Mangekyō Sharingan can handle it.

Yichen asked Ōnoki, "Shinno didn't do anything strange, did he?"

Ōnoki shook his head and said, "He's still very honest; he hasn't done anything besides giving pointers to Uzumaki Karin Sakura Haruno."

Yichen glanced at Hu, who was staring Byakugan wide open, and nodded.

After confirming that Shinno was still behaving himself, Yichen went to the hospital's laboratory.

Here, Shinno is teaching Karin and Sakura his unique Medical Ninjutsu.

Shinno greeted Yichen with a kind smile and said, "Greetings, Lord Tsuchikage."

Yichen, also beaming, said, "Thank you for your hard work these past few days, Senior Shinno."

Shinno smiled and said, "Both children are exceptionally talented, and I like them very much."

Yichen said, "Then I'll have to trouble you to take extra care, senior."

After a very pleasant chat, Shinno ignored Yichen and continued to instruct the two children.

After watching Shinno teach Karin and Sakura for a while, Yichen nodded in approval. Shinno had indeed shown his true skills as Yichen had requested.

Shinno's Medical Ninjutsu is more accurately described as Medical Ninjutsu.

His abilities are more focused on the Yichen's previous life.

Similar to surgery, Shinno possessed a set of methods for understanding the internal organs, bandaging, stopping bleeding, and detoxifying, which differed from conventional Medical Ninjutsu today.

Shinno's medical skills may not be comparable to Tsunade's, but his unique methods can greatly help improve the Medical Ninjutsu of Iwagakure.

Yichen had high hopes for Sakura, but in this life, Sakura could no longer become Tsunade like in the original story. Therefore, Yichen had to improve Sakura's Medical Ninjutsu skills in other ways.

Seeing that Karin and Sakura were indeed studying very diligently and achieving good results, Yichen left the laboratory with peace of mind.

After leaving the laboratory, Yichen encountered Nakata Hajime, the Medical Department, who was waiting for him outside.

Nakata Hajime glanced at the closed laboratory door and said, "Lord Tsuchikage, is there something wrong with that Senior Shinno?"

Yichen nodded and said to Nakata Hajime, "When you interact with them, keep a Mind's Eye. This is the leader of the Sky Ninja Village, which was destroyed by Konoha during Second Shinobi War."

"His strength is considerable; if he uses all his abilities, he could rival Kage Level expert."

"Furthermore, he's a very skilled intelligence ninja; don't let him get close to the hospital's secret facilities."

Nakata Hajime swallowed hard and stammered, "Kage Level? Lord Tsuchikage, isn't it a bit inappropriate to put such a dangerous guy in the hospital?"

"Should we set up a laboratory outside the village so he can teach Sakura and Karin there?"

"It would be best to have the two of them go to school separately, taking turns. If this person goes crazy, we'll suffer a huge loss."

Yichen glanced at him and said, "Don't worry, the Third Hokage is watching him from not far away. If he dares to make a move, the Third Hokage will kill him on the spot."

"You don't need to worry about force. Besides, it's just a Kage Level. The village already has double-digit numbers of Kage Level characters. What are you afraid of?"

"Don't worry, just act like the powerful minister of the number one Great Ninja Village. No Kage Level ninja will dare to make a move in the village unless they're here to take everyone down with them."

Nakata Hajime smiled wryly. Yichen made it sound so easy. If Shinno really acted recklessly, even if the Third Generation intervened, the hospital would likely suffer heavy losses.

At that point, he, the powerful minister of the number one Great Ninja Village, will probably only be able to show off his power in another world.

Ignoring Nakata Hajime's inner monologue, Yichen left the hospital directly.

After leaving the hospital, Yichen went to the Anbu Prison.

Shinno's Medical Ninjutsu reminded Yichen of another person who had also forged his own path in Medical Ninjutsu: Yomi.

Since Yichen and the Miko joined forces to defeat the Moryo and brought Yomi, who carried part of the Moryo's power, to Iwagakure, Yichen had forgotten about him.

Yichen was very concerned about the Dark Medical Ninjutsu invented by Yomi in the original work.

So they imprisoned Yomi in Iwagakure and had him conduct research on him. They don't know how his research is going.

Yichen arrived at the Anbu Prison. After confirming his identity, he entered the Prison and met Yomi.

When I met Yomi, he was conducting experiments on animals.

Over the years, Yomi, who has been staying in the Iwagakure Prison, has not been idle. According to his agreement with Yichen, his main job is to do research.

The Iwagakure would provide him with live animals for his experiments, including small animals and prisoners from other countries.

For example, after defeating the Sunagakure several times, the Iwagakure captured many prisoners. Every time they occupied new territory, the Iwa ninja would capture many more prisoners while clearing out wandering and missing-nin ninja.

Some of these prisoners were released by Yichen, though not for free.

A significant number of them were also controlled by the Iwa ninja using special methods and became ninjas who worked specifically for the Iwagakure.

For example, when searching for gold in the Land of Wind, after the Fourth Kazekage Puppet unearthed the gold, ninjas were needed to transport it.

For example, every time a new branch is built, there is a lot of physically demanding and physically exhausting work.

The main force behind this arduous task was the prisoners of war.

Unlike Danzo, Yichen doesn't wear his villainy on his sleeve, but in some ways, his methods are no less lenient than Danzo's.

Most of the remaining prisoners became guinea pigs in various laboratories of Iwagakure.

These Sunagakure witnessed the darkest part hidden beneath the glamorous exterior of the Iwa ninja's rise to power.

The human body was not only secretly operated on here in the Yomi, but also in the White Zetsu clone laboratory, the newly established First Hokage's Cells Laboratory, and the secret operating room of the Medical Department.

Even Katsuya and Natsuki's Yin Release laboratory occasionally used ninjas from other countries for experiments.

Even when the Barrier Team researched various seals and barriers, they would use prisoners as practice subjects.

When Atsumi Akino makes progress in her Space-Time Ninjutsu, she will first test it on prisoners.

Many Sunagakure or wandering ninjas also died during Space Teleportation.

The organization that consumed the most prisoners was the Anbu. As Iwagakure continued to expand its army, the average combat experience for the village's ninjas decreased.

To ensure the combat effectiveness of the Anbu, Yichen once ordered that the number of prisoners needed for the Anbu's training must be guaranteed.

This order meant to institutionalize the practice of using prisoners to train new recruits for the Anbu.

The Anbu's training is all about real combat; a moment's carelessness can cost a prisoner their life. That's why the Anbu have been the main source of prisoners for Iwagakure in recent years.

The strongest prisoner of Iwagakure was Shisui Uchiha, Shisui Uchiha also served as his sparring partner the most times.

Most of the Anbu of Iwagakure have fought against Body Flicker Shisui. Some have done it more than once.

Yomi's place was just one of many laboratories in Iwagakure, where he also conducted many human experiments.

Yomi, who was conducting an experiment, was taken aback when he saw Yichen suddenly appear at the laboratory door. Yichen had never been here before.

In that moment of hesitation, the rabbit in his hand lost its life because it missed the opportunity for timely treatment.

Yomi naturally recognized Yichen and respectfully said, "Lord Tsuchikage."

Yichen walked into Yomi's cell and said expressionlessly, "Yomi, we made a promise before."

"You worked for Iwagakure for ten years, and I'll release you after ten years."

"Although it's been less than ten years, I need your experimental results."

"Now tell me all your experimental results. If I'm satisfied, I'll set you free. If I'm not satisfied, then I'm sorry."

Yomi's breath hitched. He didn't actually believe Yichen's ten-year promise; he had been waiting for the right opportunity.

Wait for the day when Iwagakure is attacked, and when Iwagakure's defenses are in disarray, that will be the time for me to escape.

Yomi believed that the Iwa ninja wouldn't keep such a tight watch on him forever.

But after waiting for more than six years, Yomi still hadn't witnessed the day when Iwagakure would descend into chaos.

He couldn't understand it. Had there been no major war in the Ninja World for over six years?

Even without the Ninja World War, has Iwagakure never experienced a single Tailed Beast rampage?

The longer time passed, the more desperate Yomi became. He had decided that in two more years, when there was still a little over a year left in the ten-year period, he would forcibly escape.

Despite being in the most heavily guarded Anbu of Iwagakure, Yomi was confident that, based on the results of his research over the years, he had at least a 30% chance of leaving Iwagakure undetected.

But Yomi didn't expect that just over six years later, Yichen would come looking for him so impatiently.

Has Iwagakure finally encountered a crisis? Should I try to negotiate with them?

But what Yichen said made his heart sink.

That's not how you negotiate! Shouldn't negotiations involve asking for the absolute highest price and then settling for a lower one?

Why do they push people to the brink right from the start?

Yomi calmed himself down. He wanted to test the waters further, so he asked, "Lord Tsuchikage, my experimental plan was supposed to last ten years, but it's only been six years. The results may not satisfy you."

Yichen said calmly, "It doesn't matter if you can't satisfy me. Just kill you, and I won't lose anything."

Yomi's face twitched. While cursing Yichen in his heart, he said, "Lord Tsuchikage is joking. I will tell you the results right away."

Then, Yomi Hand Seals and performed a Ninjutsu similar to Earth Release, saying, "Lord Tsuchikage, considering that your village mainly uses Earth Release, I have researched a special Earth Release."

"A Ninjutsu that can turn the entire body into mud. I'll write down the whole Ninjutsu in a bit."

As Yomi spoke, one of his arms turned entirely into earth, then turned back into a hand, repeating this several times.

When he turned into soil, he was still using a scalpel to chop with his other hand, but when the soil turned back into a hand, there were no wounds on his hand.

This Ninjutsu is different from the Hardening Jutsu used by the Iwagakure.

Hardening Jutsu only enhances defense, but this Ninjutsu can turn the entire body into earth in a short period of time.

Once transformed into earth, the ninja will not be injured by any attack. As long as the earth remains, they will be fine once they revert to human form.

If used properly, this Ninjutsu can indeed enhance the combat power of Iwa ninja.

Yichen remained expressionless, simply staring at Yomi without uttering a word.

Yomi swallowed hard and said, "Lord Tsuchikage, I've also figured out similar methods for the other four attributes besides Earth Release."

"The Lord Tsuchikage is multi-attribute, so I think Lord Tsuchikage can use this ability."

Seeing that Yichen remained unmoved, Yomi gave a wry smile and said, "Lord Tsuchikage, these really are all my achievements."

Yichen said, "It seems you are very confident in your Medical Ninjutsu, believing you can pull off a miraculous comeback and escape from my clutches?"

As he spoke, Yichen One-handed Hand Seals, and before Yomi could react, a C-rank Light Release struck his arm directly.

Yomi didn't expect Yichen to act so quickly. Although he had been on guard, he was hit by the Light Release before he could react.

Yomi quickly retreated to the corner, took out a scalpel, and looked at Yichen warily.

Seeing that Yichen didn't make a move, he then touched his empty left arm with his right hand.

Yomi's face was grim. He hadn't even seen how Yichen made his move, and his left arm was gone.

Seeing that only a little blood was flowing from the severed part of Yomi's left arm, Yichen said, "This is the result of your lack of cooperation."

"Come on, try it in front of me and see if you can restore your left arm, which was directly vaporized by my Light Release."

Yomi forced a smile and said, "So, Lord Tsuchikage was referring to Medical Ninjutsu."

"Lord Tsuchikage, you misunderstand. I have indeed researched some Medical Ninjutsu over the past six years, but I haven't fully succeeded in researching it yet."

"I originally intended to hand them over to Lord Tsuchikage, but those were just ideas that hadn't been researched and weren't up to standard."

Yichen smiled and said, "Oh? Is that so? I'm so sorry, I misunderstood."

"Then please tell me in detail how far your Medical Ninjutsu research has progressed. Be clear this time, so I don't misunderstand again."

Yomi's lips twitched as he said, "Don't worry Lord Tsuchikage, I will definitely tell the truth."

Yomi was feeling very aggrieved. He had never intended to teach the Dark Medical Ninjutsu to Iwagakure. It was his biggest Trump Card for establishing himself in the Ninja World.

But having been forced into this situation by Yichen, he had no choice but to produce some substantial content.

In just a few breaths, Yomi had already prepared his explanation. "Lord Tsuchikage, the Dark Medical Ninjutsu I've researched is different from conventional Medical Ninjutsu."

"If the Iwagakure learns this Ninjutsu, it will greatly improve the healing rate of injuries..."

After hearing Yomi's description, Yichen turned and left the Prison.

Yomi called out nervously from behind, "Lord Tsuchikage?"

Without turning his head, Yichen said, "Write down everything you know."

"I keep my word, so you should think it over carefully. Also, see if your Dark Medical Ninjutsu can heal the damage caused by Light Release."

"This is your last chance, don't let yourself down. I'll come to collect your answer sheet in three days."

After Yichen disappeared, Yomi put away his uneasy expression and looked in the direction Yichen had left, his eyes filled with solemnity.

For some reason, at this moment, Yomi felt a sense that Yichen already knew about his research results.

Shaking his head, Yomi Quan banished the unfounded thought from his mind and began to try to treat his missing arm with Dark Medical Ninjutsu.

However, at that moment, Yichen wasn't thinking about how to heal his injuries; his mind was focused on the wounds.

Yomi, who was about to make his move, was dumbfounded.

"My... my left hand is gone? How can I fix this?"

Just now, due to the suddenness of the situation, he thought that Yichen had only cut off his left arm.

Yichen moved too quickly; he didn't see clearly. He assumed his left arm should be inside the room.

However, he now realized that his left arm had been vaporized by the Light Release technique.

The Dark Medical Ninjutsu he developed was indeed miraculous, capable of achieving immortality to a large extent.

But all of this is contingent on the body still being intact.

Even if his head is cut off, he can still come back to life as long as his body is still intact.

But what about attacks that directly vaporize?

Sweat began to drip from Yomi's forehead.

He recalled Yichen's words, "Let's see if your Dark Medical Ninjutsu can heal the damage from the Light Release."

When Yichen captured Yomi, he did not use his Light Release. Yomi had been imprisoned in the Anbu for many years and was unaware that Yichen's Light Shield had already made a name for itself in the Ninja World.

Yomi was immediately gripped by immense panic.

He could imagine that if the research results he handed over to Yichen three days later did not satisfy him, Yichen would definitely choose to kill him.

Moreover, the way Yichen executed him was definitely not by chopping him with a weapon as he had previously thought; it was more likely that he used some kind of Light Release to vaporize him.

At that point, all his ambitions and efforts will be meaningless.

However, he felt unwilling to simply write down all his research findings.

He still wants revenge on Iwagakure, how can he just give in like this?

"Damn it, how can there still be such attacks in the Ninja World?" Yomi cursed angrily.

This is the tragedy of ninjas who came from humble backgrounds.

Any ninja trained at the Ninja Academy in a normal Great Ninja Village, unless they are an idiot like Naruto, should know that the Dust Release of Iwagakure Third Tsuchikage of Ōnoki, can cause similar damage.

But Yomi, being rather ignorant, was unaware of these things.

Yomi paced back and forth in the room, caught in a dilemma.

Three days later, Yichen returned to the Anbu Prison, this time bringing with Katsuya Yichen Izumi Uchiha.

Yomi's heart skipped a beat when he saw Yichen arrive, accompanied by two ninjas dressed as Anbu.

Logically speaking, Yichen alone should have been enough to deal with him, so why go to the trouble of bringing two subordinates along?

A bad feeling rose in Yomi's heart.

He quickly said, "Lord Tsuchikage, please wait a moment, I still have some things to write."

Yichen said, "No rush, you write yours, I'll take a look at what you've already written."

As he spoke, Yichen created a Shadow Clone, Shadow Clone picked up several scrolls that Yomi had placed on the table.

Yomi tentatively asked, "Lord Tsuchikage, who are these two?"

Yichen smiled and said, "These two were specially invited to check if you had missed anything."

"These two, one knows a bit of Genjutsu, and the other knows a bit of Yin Release."

"Don't worry, as long as you don't hold anything back, they won't do anything to you."

Yomi's lips twitched. As he wrote, he asked, "Genjutsu? So the Iwagakure has been researching Genjutsu all these years?"

Yomi knew that the Iwagakure was not good at Genjutsu, so he was not afraid of the Iwa ninja using Genjutsu on him.

Yichen laughed, "Quan Luo, it seems he doesn't believe in the Genjutsu of your Uchiha Clan."

Izumi Uchiha forward, and the jet-black eyes revealed behind the Anbu standard mask instantly turned scarlet.

The next moment, Yomi lost consciousness.

When he came to his senses again, the Anbu in front of him had already retreated to their previous positions.

"Sharingan? That was the Sharingan just now? The Iwagakure actually has the Sharingan?" Yomi was shocked.

He thought he'd misheard when he first heard the name Uchiha. When did Uchiha become part of Iwagakure?

"Wait, the Sharingan's pattern is shaped like Tomoe. What was that pattern just now?" Yomi suddenly remembered something and pondered.

"I've studied Yin Release for so long, and I can't even defend against Genjutsu? Are the Sharingan of the Uchiha Clan really that powerful?"

"Wait, what exactly did I say when I was under the Genjutsu?"

Thinking of this, Yomi quickly looked at Yichen.

Then Yichen said, "Yomi, you're really amazing. I didn't even see through all thirteen traps you set."

"I'm considered one of the top ninjas in the Ninja World in terms of mastery of the Five-Attribute Ninjutsu. To be able to deceive my eyes, Yomi, you're quite remarkable."

Yomi felt a chill run down his spine upon hearing Yichen's praise.

Thirteen traps, not one more and not one less; it seems I've revealed everything in the Genjutsu.

After weighing the options for three days, Yomi finally decided to take a gamble.

Therefore, he deliberately did not write out the core part of the Dark Medical Ninjutsu at the beginning. Only after seeing Izumi Uchiha and Katsuya brought by Yichen did he pretend to be afraid and intend to write it out on the spot.

He had already planned it out; when writing about Dark Medical Ninjutsu, he would set several traps in the most crucial parts, so that everyone in Iwagakure who trained in it would eventually kill themselves.

But who would have thought that before he even started writing, Yichen would give him a hard time?

Yomi quickly said, "Lord Tsuchikage, I'll correct it right away and write out the complete Dark Medical Ninjutsu."

As he spoke, he grabbed the scroll that had already been written on from the table, found the place where the trap had been set, and began to revise it.

After revising all thirteen parts, Yomi quickly wrote down the core content of the Dark Medical Ninjutsu.

After finishing writing, Yichen Izumi Uchiha again.

Izumi Uchiha and once again used Genjutsu at the level of the Mangekyō Sharingan on Yomi.

However, after Genjutsu in Yomi this time, Katsuya stepped forward and together with Yichen, placed a hidden seal on Yomi's soul.

This seal is similar to the Cursed Tongue Eradication Seal, which can prevent Yomi from directly sealing away what he saw and heard in Iwagakure.

Although he still remembered it, he couldn't bring himself to say it.

Then Yichen took some blood from Yomi to locate Chiga, just in case.

After a long time, when Yomi awoke from the Genjutsu, he found that he had left the Iwagakure Anbu Prison where he had been for more than six years.

He looked around and found himself in a deserted mountainous area.

"The Iwa ninja actually let me go?" Yomi was somewhat incredulous.

Then he looked at his lost left arm, and a look of deep regret appeared in his eyes.

If he had known Yichen would really let him go, he would have cooperated obediently from the beginning, and wouldn't have had to lose an arm for it.
