"I didn't expect that one day I would travel to Konoha, and... what's more, I would end up being an intern teacher after arriving."
"Seriously?!"
Kanda Keiichi sat in the office, doubting his life choices.
Just the day before, he had been suffering from headaches caused by unruly elementary school kids who didn't like male teachers. Now, not only did he no longer have to worry about being fired or receiving complaints from parents, but...
Looking at the noisy children outside, he couldn't feel even a trace of excitement.
The ninja world was too dangerous!
Konoha was relatively safe, but it had still suffered through countless disasters over the years.
In fact—
Just a few days ago, the Battle of Kannabi Bridge had ended. Jingyi was injured and returned to the village. After a brief recovery, he was assigned to the Ninja Academy as a teacher.
"Alas, it's a pity that the Senju Clan has long since declined. Otherwise, I could've coasted through life with that backing..."
Jingyi sighed.
The Kanda family carried a trace of Senju blood.
The Senju Clan had once been glorious.
But since the time of the First Hokage, the clan had gradually merged into the village structure. After the Second Hokage, only a handful of direct descendants remained. Now…
Tsunade-hime was practically the last true bearer of the Senju name.
And even she didn't officially use "Senju" as her surname. So, Kanda Keiichi couldn't enjoy any clan privileges.
He figured the Senju blood in his veins was extremely diluted—
Certainly not stronger than Tsunade's own granddaughter, should she ever have one.
Forget about the Sage Body.
His talent...
At fifteen or sixteen, he was still only a Chūnin. Nothing exceptional.
Jingyi was genuinely worried.
At this rate, living to old age was questionable. Konoha was still destined to face numerous calamities.The Third Great Ninja War, the Nine-Tails' Attack, Orochimaru's invasion, and more.
A mere Chūnin facing those kinds of threats? Like a mayfly shaking a tree.
Even the shockwaves could kill him.
"Maybe I should look into acquiring some of Hashirama's cells. I might stand a chance of awakening Wood Release that way..."
Jingyi muttered to himself.
This world was unforgiving.
If he didn't get stronger, he was as good as dead.
He was lost in thought when the bell rang.
Class had ended.
"Looks like it's time for me to go teach the next session."
Jingyi was mainly in charge of teaching "Ninjutsu."
He wasn't sure why he was given that class at first. After asking around, he learned the previous instructor had died on the front lines, and the academy urgently needed a replacement.
That's how he ended up as an intern.
Well, off to class.
The Academy's ninjutsu lessons weren't too hard. With the knowledge in his head, he could easily handle teaching the basic Three Techniques.
Just as he stood up, a strange voice echoed in his mind.
At first, it was faint.
But then, clearer—
[Mentor System is activating...]
[Activation complete!]
[Diligent teaching will earn rewards. Becoming a life mentor will yield bonus rewards.]
[You currently have a novice gift package. Would you like to claim it?]
A system?
A gift pack?
What was this...
A signing bonus for transmigrators?
Jingyi paused, then inwardly replied, "Claim it!"
[Your proficiency with the Three Techniques has been maxed out.]
[You've received a reward: Bloodline Purification.]
[Your bloodline has been purified and upgraded to that of the Senju. Your physique has been greatly enhanced.]
[Your Earth Release and Water Release techniques have been improved.]
In the corridor, Jingyi was suddenly flooded with knowledge and instincts related to the Three Techniques. Then, he felt his blood boiling.
His body temperature surged.
Was this the purification effect?
He was stunned at first, then overjoyed.
The Senju bloodline!
Just the improvements to his physique, Earth Release, and Water Release were significant.
Not to mention
A stronger physique meant more chakra.
There were bound to be more benefits down the road.
A clearer lineage, compatibility with Hashirama's cells this had massive potential.
Plus, he had the Mentor System. If the beginner gift was this good, perhaps he could eventually unlock the Sage Body or even the Rinnegan?
With this system, he might actually survive this chaotic world.
Jingyi couldn't contain his excitement.
"I wonder what the 'life mentor' part means..."
He pondered.
According to the system, teaching students attentively would yield rewards, but becoming a "life mentor" would yield even more.
But what exactly was a life mentor?
Jingyi decided not to think too hard. He had a class to teach.
Time to see who his students were.
After the bloodline purification, he quickly noticed changes in his body.
Even his walking speed had increased!
At the classroom door, he spotted a familiar figure.
Uchiha Obito.
This guy...
"Are you Uchiha Obito?"
"Yes, sensei."
Obito looked a little awkward and nervous as he stood by the door.
"Go on in and take your seat."
No doubt about it.
Late again.
Inside, Jingyi saw many familiar faces.
Rin. Kurenai Yuhi. Sarutobi Asuma.
Also—
Shisui, Anko, and Hayate were in the class too.
Due to the war, Konoha's manpower was stretched thin.
Many teachers had been deployed to the front lines, so students with small age gaps were grouped together. It was a stopgap measure just like Jingyi's appointment.
"Hello everyone. My name is Kanda Keiichi. I'll be your new ninjutsu instructor."
"Sensei! I heard you just got back from the battlefield! Can you teach us some real ninjutsu?"
Obito immediately shouted.
This guy wasn't shy at all.
A classic extrovert. Acting like they were old pals, even though they had just met.
Jingyi gave him a tired look.
But Rin and Yuhihiko were also curious and excited about their new instructor who had real combat experience.
They were clearly eager to graduate early.
New jutsu and battle training? Right up their alley.
However
Aside from the Three Techniques, Jingyi's repertoire only included the Shadow Clone, Body Flicker, Water Wall, and Water Bullet techniques. And he couldn't just teach all of those right away.
With a slight smirk, he surveyed the room.
"Do you all think your Three Techniques are perfect and don't need practice anymore?"
No one replied, but their smug faces said enough.
"Alright. For today's first lesson, we'll focus on the Three Techniques. Prove you've mastered them to my standards, and I'll consider teaching you something new."
Jingyi grinned.
With his max-level mastery, he was more than qualified to teach.
These kids wanted to sprint before they could walk?
"Let's move to the training field."
"Okay!"
At the training field, Jingyi observed the group.
There were some real geniuses here. But truth be told, Obito could rank in the top five. Hrle just hadn't awakened his Sharingan yet.
Besides him...
There was Shisui.
"Obito, Shisui—step forward."
"Yes!"
Both stepped into the middle.
A two-on-one?
"Attack me together—with everything you've got!"
