Both time-traveled characters ended up as villainous henchmen.

"Congratulations, Izumi Nen-kun, your application for early graduation has been approved. Here is your ninja headband, take it."

The Chunin instructor handed Izumi Nen a headband bearing the Konoha Village insignia, patted him on the shoulder with delight, and said:

"The teacher initially thought you were joking about graduating early, but it turns out the teacher misjudged you."

Keep it up! Work hard in the future too!

"yes!"

Izumi Nian took the headband and put it on his head decisively, his face full of excitement and anticipation.

After saying goodbye to the teacher and leaving the classroom, his expression quickly returned to normal, and his headband was put away again.

"Next, it's a race against time."

Izumi Nen murmured to himself as he hurried toward Konoha Hospital.

Konoha Hospital.

"Hey? You're the classmate Lin was talking about, right? You're here so soon, I thought you'd be a few days away..."

"Alright, come with your older sister, Izumi is going to talk to your younger brother."

"Okay, thank you very much, sister."

Izumi smiled sweetly, displaying her politeness and obedience.

This scene, witnessed by the nurse, immediately brought even more joy to her eyes.

What a polite and adorable child!

After successfully passing the test, Izumi Nen was led by a nurse to the special medical ninja testing room.

The test for Yang Release chakra was passed easily.

Next comes the testing of theoretical knowledge and practical operation.

These tests take a long time and are the period when changes are most likely to occur.

The chances of Root directly snatching people from Konoha Hospital are slim, since this is still Tsunade's territory.

What Izumi Nen needs to consider is the situation after the subsequent tests are completed and he leaves Konoha Hospital.

While mentally rehearsing various possibilities, Izumi Nen began testing his theoretical knowledge.

After sharing the power of space, he not only improved his strength, but also greatly enhanced his talent, memory, and mental agility.

With this month of preparation, there are no problems with the theoretical knowledge and the subsequent practical assessment.

The problem lies outside the examination room.

……

A stronghold somewhere at the base.

Danzo Shimura is conducting a routine inspection of the internal affairs of the Root.

The power within the organization was highly centralized, with almost all matters decided by Danzo Shimura.

Although Danzo doesn't handle every trivial matter, he does inquire about most of the minor details.

The news that Izumi Nen had suddenly graduated from the Ninja Academy was quickly delivered to Danzo afterwards.

"Izumi..."

Shimura Danzo took the intelligence scroll and hesitated for a moment over the surname Izumi before slowly recalling a hunched and thin man from the depths of his memory.

Izumi Nen, it was actually this child! He actually had such talent, able to graduate from the Ninja Academy early.

That was a real oversight.

After leaving the Ninja Academy, he went to Konoha Hospital, which suggests that he also has a talent for medical ninjutsu, which he has kept well hidden.

But in the end, he was just a child.

To think you can get rid of me by relying on Tsunade's power is a bit too naive.

In that case, I'll "help" you out.

"Since he wants to become a medical ninja, have someone inform the Konoha Hospital, and then have him return to Root for training."

Shimura Danzo remained expressionless and quickly arranged Izumi Nen's future. He then put the matter of Izumi Nen out of his mind, as it was a trivial matter and not worth his time. He could leave it to his subordinates to handle.

As soon as Danzo Shimura gave the order, a Root ninja wearing a rabbit mask quickly emerged from the shadows in the corner, acknowledged the order, and then swiftly disappeared.

Danzo ignored him and continued to examine other matters related to the root.

……

Konoha Hospital.

The Root ninjas were indeed highly efficient. Less than half an hour after Danzo gave the order, Izumi Nen's detailed information, especially the obscure relationship between the Izumi family and Root, was successfully mixed into Izumi Nen's ninja academy graduation information and submitted to the medical ninja examinee's file.

Soon, the file with its subtle "oddities" was taken out separately by the hospital staff.

After cross-examination by several responsible personnel, it was determined that the file showed signs of forgery.

This file, specially made by Root, was then delivered to Tsunade.

Since the Second Shinobi World War, Tsunade has suffered from hemophobia due to the deaths of her younger brother, Nawaki Senju, and her lover, Dan Kato.

Therefore, she had to step down from the front lines of medical work and instead focus her efforts on reforming the Konoha medical system.

Tsunade was already tired of the power struggles between the village's high-ranking officials and the various ninja clans, so she wanted to create a new Konoha medical system that was a more pure organization.

It is by no means a bargaining chip in any open or covert struggle, nor a cake to be taken at will.

"Lady Tsunade."

"Please come in."

Tsunade was preoccupied with a large amount of documents on the table, and without even looking up when she heard this, she simply told someone to come in.

"Lady Tsunade, among the applicants for medical ninja this time, there is a problem with one person's file. There are very subtle signs of alteration, and this person seems to be from Root."

Upon hearing the words "Root," Tsunade finally raised her head and looked at the medical ninja who was reporting to her.

"Let me see the file."

After sighing and rubbing her forehead, Tsunade took Izumi Nen's file and glanced at the marked suspicious points.

"Danzo...hasn't he given up after all these attempts?"

Tsunade has dealt with several instances of Root attempting to infiltrate Konoha Hospital, but Danzo continues to do so repeatedly.

The Third Hokage only tried to smooth things over, at most issuing verbal warnings, which made her quite angry.

"Izumi Nen, you just graduated from the Ninja Academy and you're applying now? You're taking the theory exam right now."

It seems that old guy put in some effort this time, but he still hasn't changed his old habits...

After quickly scanning through the documents, Tsunade closed Izumi Nen's file and ordered, "The same procedure applies: reject the application!"

"Yes, Lady Tsunade!"

……

After three hours of various tests, Izumi Nen left Konoha Hospital with a calm expression.

His expression remained normal, though his eyes seemed to be suppressing joy and excitement.

The Root ninjas who were secretly monitoring and following him became even more relieved upon seeing this situation. It seemed that this kid had not yet realized that his plan had been exposed.

He then followed without making a sound.

They are still within the Konoha Hospital area, so it's not advisable to arrest them directly to avoid causing unnecessary accidents.

Just as the Root ninja followed Izumi Nen around a small alley and was about to make his move, a puff of smoke appeared, leaving only a wooden stake as a substitute.

Meanwhile, after shaking off the Root ninjas, Izumi Nen neither returned to Konoha Hospital nor went to the vicinity of buildings with high-ranking ninjas, such as the Hokage Building, but instead sped towards a dense forest.

In the dim, dense forest, Izumi Nen skillfully navigated various obstacles and finally stopped at a clearing by a stream.

"Come out, I know you've been waiting for a long time."

Izumi Nen spoke calmly in the direction where no one was, his expression showing no sign of panic.

Long after he finished speaking, a twisted, boneless figure, resembling a snake, slowly descended from the tree branch.

Her long hair cascaded down her shoulders, her skin was deathly pale, and only her eerie snake-like eyes gleamed faintly.

The visitor was none other than Orochimaru.
