Life Mentor System

"I never imagined that one day I'd transmigrate to Konoha, and... damn it, after transmigrating, I'd still end up as an intern teacher."

"Damn it!"

Kanda Kyoichi sat in the office, questioning his entire life.

Just the day before, he had still been worrying over the fact that the brats at his elementary school disliked male teachers. He never expected that, on the second day, he wouldn't have to worry about unemployment or complaints from parents anymore. And now...

Looking at the noisy children outside, he couldn't feel the slightest bit of excitement.

The ninja world was too dangerous!

Konoha was relatively safe, but disasters had continued one after another throughout the years.

For example.

The Kikyo Mountain Battle had only ended a few days ago. After Kyoichi returned to the village injured, he had been assigned to teach at the Ninja Academy once his wounds had initially healed.

"Sigh. It's a shame the Senju Clan declined so long ago. Otherwise, I could have relied on the Senju and freeloaded my way through life..."

Kyoichi sighed.

The Kanda family had Senju bloodline.

The Senju Clan had once been incredibly glorious.

But.

Starting from the First Hokage, the Senju family had continued to split apart and integrate into Konoha. By the time of the Second Hokage, the Senju Clan had basically been reduced to a small number of direct descendants. And now...

Basically, the only person who could truly be considered part of the Senju family was Princess Tsunade.

However.

Even Tsunade didn't actually use "Senju" as her surname, so Kanda Kyoichi couldn't enjoy any of the benefits of being a member of the Senju Clan.

He estimated that the Senju bloodline in his body wasn't very concentrated either—

At least, it couldn't possibly be purer than that of the granddaughter of the clan, Tsunade.

He could forget about the Sage Body.

As for talent...

He was already fifteen or sixteen, yet he was still only a Chunin. It seemed that was the extent of his ability.

Kyoichi was troubled.

At this rate, whether he could live to die of old age was a question, especially since Konoha would face all kinds of disasters in the future—the Third Shinobi World War, Nine-Tails' Night, the Konoha Collapse Plan, and so on.

A Chunin facing those enemies would be no different from an ant trying to shake a tree.

Even the shockwaves could take his life.

"Maybe I should find some Hashirama Cells later on. Perhaps I'll still have a chance to master Wood Release."

Kyoichi thought to himself.

The ninja world was too dangerous.

Without becoming stronger, he was simply waiting to die.

Just as he was pondering this, the bell rang outside.

Class was over.

"I think I have the next class."

Kyoichi mainly taught "ninjutsu."

He didn't understand why he had been assigned to teach this. After asking around, it seemed that the previous teacher had died on the front lines, leaving the position vacant, so they had temporarily grabbed anyone available to fill it.

Thus, Kyoichi was only an intern.

Whatever. He might as well go teach the class first.

The academy's ninjutsu lessons weren't difficult anyway. They were just the Three Body Techniques. The memories in his head were more than enough to fool a bunch of children.

Kyoichi was thinking this when he had just risen to his feet and a strange voice suddenly rang out.

At first, he couldn't make it out.

But.

He understood it a moment later.

[The Mentor System is activating...]

[Activation successful!]

[You can obtain rewards by wholeheartedly teaching students. Becoming a life mentor will grant even more additional rewards.]

[There is currently a novice gift pack. Would you like to claim it?]

Host:

The Mentor System?

A novice gift pack?

What was this supposed to be...

A welcome package for starting work?

Kyoichi froze for a moment before thinking, "Claim it!"

"Your Three Body Techniques proficiency has been raised to the maximum."

"You have received a reward: Bloodline Purification."

"Your bloodline has been purified, upgrading it to Senju bloodline. Your physique has been greatly enhanced."

"The effects of your Earth Release and Water Release have been enhanced."

In the hallway, a great deal of knowledge about the Three Body Techniques suddenly appeared in Kyoichi's mind, including their applications and principles. Then, he felt his entire body surge with boiling blood.

He could tell that his body temperature was skyrocketing.

Was this the effect of purification?

He was somewhat dumbfounded at first, but then an overwhelming wave of joy surged through him.

Senju bloodline!

Even just judging from the immediate effects, the improvements to his physique, Earth Release, and Water Release were obvious.

Moreover.

A stronger physique meant that his chakra reserves had also increased.

That would bring even greater benefits in the future.

His identity, compatibility with Hashirama Cells, and so on—all of that was worth looking forward to.

What was more, he had this so-called "Mentor System." The novice gift pack was already so powerful. Perhaps he might even have a chance to obtain the Sage Body or even the Rinnegan in the future.

With this system, he finally had a chance to survive in the ninja world.

Kyoichi couldn't help feeling excited.

"I wonder what the Mentor System is like..."

He pondered this secretly.

From the system's prompt, he could obtain rewards simply by wholeheartedly teaching students. But afterward, it had mentioned that becoming a life mentor would grant even more rewards.

However.

What exactly was a life mentor?

After thinking it over again and again, Kyoichi decided not to dwell on it for now. He would go to the classroom first and think about it later.

He wanted to see who exactly his students were.

After his bloodline had been purified, he quickly noticed the changes in his physique.

Putting everything else aside, he could walk much faster than before!

At the classroom door, he saw a familiar face.

Uchiha Obito.

This guy...

"You're Uchiha Obito?"

"Yes, teacher."

When Obito saw Kyoichi, he became somewhat flustered. He stood at the door, fidgeting awkwardly.

"Go inside and sit down."

There was no need to think about it.

He had definitely been late again.

After entering, Kyoichi saw quite a few familiar faces.

Rin, Kurenai Yuhi, and Asuma.

Besides them.

Shisui, Anko, and Hayate were also in the class.

Manpower was scarce during wartime.

Many teachers had gone to the front lines, so students of roughly similar ages at the Ninja Academy had been combined into one class for instruction. It was a temporary policy, something they had no choice but to do—

Including Kyoichi's temporary recruitment.

"Hello, everyone. My name is Kanda Kyoichi, and I'll be your ninjutsu teacher from now on."

"Teacher, teacher! I heard you just came back from the battlefield. Can you teach us some more practical ninjutsu?"

The moment Obito saw Kyoichi enter, he immediately shouted.

This guy was genuinely fearless around strangers.

He had a pure case of excessive sociability. He had only met Kyoichi once moments ago, yet he acted as if they had known each other for years.

Kyoichi looked at him speechlessly.

But.

Aside from him, Kurenai Yuhi, Rin, and the others were also curious about a teacher who had returned from the battlefield, and they held some expectations.

They all wanted to graduate early.

Thus, the battlefield and new ninjutsu were things they yearned for.

However.

Of all the ninjutsu Kyoichi knew, apart from the Three Body Techniques, he only had Shadow Clone, Body Flicker Technique, Water Wave Technique, and Water Wall Technique. It was impossible for him to teach those to them, and besides...

With a half-smile, he looked around and said, "Do you all think your Three Body Techniques are already completely up to standard and that you don't need to practice anymore?"

No one answered, but the expressions on all the children's faces showed that they agreed.

"All right. Then today's first lesson will be teaching you the Three Body Techniques. If you think you can meet my standards, what's wrong with me teaching you some new ninjutsu?"

Kyoichi smiled.

With his maxed-out Three Body Techniques, teaching them would be more than easy.

A bunch of little brats who hadn't even learned to walk wanted to run?

"We're going to the training ground."

"Yay!"

When they arrived at the training ground.

Kyoichi swept his gaze around.

There were quite a few geniuses here, but in terms of overall strength, Obito could at least rank among the top five—he simply didn't have the Sharingan.

Other than him.

It was probably Shisui.

"Obito, Shisui, come up here."

"Yes!"

Obito strode into the center, full of enthusiasm.

Shisui followed him out.

Two against one?

"You two attack me together with all your strength!"
