Both time-traveled characters ended up as villainous henchmen.

After a brief moment of excitement, Izumi Nen immediately realized the problem.

The immortals of the three holy lands can indeed live forever, but their strength is not top-notch. In fact, that level of power is acquired through long years.

Such a time-consuming training method is clearly incompatible with ninjas, creatures whose average lifespan is twenty or thirty years.

Moreover, after this unexpected absorption of natural energy, he also clearly sensed the extent of the improvement in his own strength.

The improvement from space sharing is almost negligible.

What ninjas need is a quick and effective way to improve their strength. The cultivation methods of the immortals in the holy land can be directly ruled out, and waiting for the power of He Nian from other worlds in the space is too uncertain.

He cannot entrust the improvement of his strength to the uncertain unknown.

Therefore, continuing to refine the ninja system is currently the best approach.

"After sharing the power of space, all my data and even my talents have undergone a transformation. The original plan is no longer usable, and a new cultivation plan needs to be developed."

Izumi Nian went to the desk, took out a brand new sheet of white paper, and began to write down a new cultivation plan.

In the original plan, because of his low natural talent, he could only try his best to improve his strength in every possible way. Among them, the only things with the highest success rate were physical skills and scientific theories.

However, he could hardly achieve either of these goals during his time at the Ninja Academy.

The only hope lies with Orochimaru. One could try to pique his interest by revealing certain qualities, or simply join his ranks to gain access to Orochimaru's experimental modifications.

The risks and uncertainties involved are extremely high, so Izumi Nen has only been quietly collecting information about Orochimaru and has not taken this step proactively.

This is his last resort besides giving up.

Of course, everything is different now.

After tonight, the former good-for-nothing Izumi Nen will be gone, replaced by the genius Izumi Nen who possesses the Sage Body and Bloodline Limit!

Special water-style techniques contain Yang-attribute chakra, so in addition to advanced water-style ninjutsu, medical ninjutsu can also be formally explored.

Although the Sage Body does not conform to the current ninja training system, it has great potential. In addition, his previous conversation with He Nian in the Black Mist Space gave him some ideas on how to further develop the Sage Body.

Sealing techniques, Sage Mode, and curse seals—these all need to be collected.

To obtain these training resources and materials, he must increase his standing within the Konoha ninja system.

It is necessary to showcase one's talents to a certain extent.

"However, we can't be too conspicuous. We need to pay attention to the reactions from the root area, and we need to find a way to get rid of it as soon as possible..."

Izumi murmured to himself, and after finalizing the plan, destroyed the white paper covered with special symbols and words.

the next day.

Izumi Nen attended classes at the Ninja Academy as usual, everything was the same, and he did not show any abnormality.

However, when he passed through the corridor after class, he encountered Obito, who was being punished for being late.

And Rin Nohara, who gently reprimanded Obito while standing beside him.

Obito also recognized Izumi Nen, the commoner ninja who had defeated him the day before.

A wave of shame and indignation washed over him, and with Lin by his side, he became even angrier.

"It's you? Izumi Nen!"

Obito's expression immediately turned ugly, but after glancing at Rin Nohara's serious expression beside him, his tone suddenly became deflated as he said, "You... don't be too smug. I'll definitely win next time."

Seeing this, Izumi Nen's mind stirred. Instead of her usual coldness, she spoke in a gentler tone, "Hello, Uchiha Obito-kun, I accept your challenge. If it's convenient, this afternoon will do. Don't be careless this time. Also…"

"Rin Nohara, you're such a kind person."

After saying that, Izumi Nen smiled slightly at Nohara Rin.

Coupled with his youthful yet already handsome face, Nohara Rin blushed slightly.

And so, Obito also became famous.

Seeing that Obito was about to unleash his power, Izumi Nen stopped in time, changed his tone, and asked sincerely:

"If I have time in the future, could I train and exchange ideas with you more often?"

"Huh?...Sure, you can do it."

Both of them were caught off guard by Izumi Nen's invitation, but after a slight hesitation, Nohara Rin was the first to accept.

"See you this afternoon then."

Watching Izumi Nen's silent figure disappear into the distance, Obito's tone suddenly changed, and he whispered to Rin beside him, "No way, this extremely quiet guy actually invited someone to train with him?"

"Perhaps Izumi just wants to improve his relationship with everyone; he doesn't seem to have many friends usually."

Nohara Rin's expression returned to normal, and she began to recall the days when she and Izumi Nen were in class.

Izumi seems like... a completely different person.

……

Izumi Nen's change of attitude towards these characters in the story, no longer indifferent, naturally had its reasons.

He wanted to build good relationships with these classmates, get in touch with Sarutobi Asuma, and thus catch the eye of the Third Hokage, Sarutobi Hiruzen.

The current third generation is not the senile and dim-witted old man he will become; he also has a certain degree of control over the roots.

Izumi Nian believed that the Third Hokage could easily find out about the affairs between the Izumi family and Root if he wanted to. If his abilities could be used to gain the Third Hokage's favor through Asuma, then the Root issue would be easily resolved.

Of course, this was just one of the preparations Izumi Nen made to resolve the Root issue; it was merely a side move.

Aside from the Third Hokage, another important figure in Konoha who can influence Root is Tsunade, one of the Legendary Sannin.

He passed the Konoha Hospital's exam and became a medical ninja, thus successfully catching Tsunade's eye.

This is the most cost-effective route among the plans prepared by Izumi Nen.

If successful, not only will you gain the protection of one of the Legendary Sannin, but you will also acquire various high-level medical ninjutsu and even the Yin Seal. You might even get all of the Second Hokage's Water Release ninjutsu and forbidden techniques.

Of course, he was also certain that the Root would never let him proceed according to plan.

Therefore, his actions had to be covert and swift, and he had to get things done completely before the root of the matter noticed anything amiss.

"I'll be busy again soon."

……

In the following days, Izumi Nen, through Obito and Rin, successfully became acquainted with Asuma and the others, and collected a lot of relevant information about the hospital assessment, and began to prepare in private.

However, to participate in the Konoha Hospital's examination and become a medical ninja, one must first graduate from the Ninja Academy.

Graduating early is clearly inconsistent with the image he has projected over the past eight years.

Therefore, he only has one chance, and he must act quickly.

Meanwhile, in order to avoid the worst-case scenario, Izumi Nen also began training in the Rasengan.

The Rasengan is a ninjutsu without hand seals, and the anime and original manga also show details of its training at various stages. It is currently the highest-level ninjutsu he has access to.

In particular, the Rasengan can also carry his special Water Release technique, which combines Water Release chakra and Yang Release chakra, further enhancing the power of the ninjutsu.

Izumi Nen trained in the Rasengan and learned about medical ninjutsu in private.

At school, he maintained his original style, except that he became more lively and cheerful and made more friends; otherwise, nothing was different.

Thus, nearly a month has passed.
