Kei Ueno knocked on Naruto's head again and said, "Make you naughty every day!" Today, there are still classes in the ninja school, are you skipping class again! ”

Kai Ueno's tone said with a little stern, after all, for Kei Ueno, Naruto Uzumaki is similar to his younger brother, and such a thing as skipping class is still not allowed by Kei Ueno.

"Hmph, Brother Qi, it's not that you haven't graduated, you have become a ninja, now you are all in the ninja, hmph, my current strength, except for the man with facial paralysis, there are few opponents in the school, and I can also graduate!" Naruto Uzumaki said with an unconvinced expression.

Three years ago, after Ueno Kai graduated early and became a ninja, he didn't tell Naruto that he joined the dark department, not only the rules of Konoha are so, the members of the dark department are not allowed to reveal their identities privately, but also because Naruto is so small and has a big personality, he definitely can't say it.

Just vaguely said that he became a ninja in advance and could perform tasks, and Naruto, who was simple-minded, didn't think much about why Kei Ueno could graduate early, but he was very envious, and praised him as his eldest brother, a genius.

This made Kei Ueno amused, and he couldn't help but breathe a sigh of relief, it's good that Naruto is a fool.

But that's also the case, Ueno Kai will guide Naruto's cultivation when he has time, which makes Naruto's actual combat strength comparable to that of the Uchiha among the students of the same level, except for the orphan of the Uchiha, and the comprehensive strength is simply the existence of the top ten or so in the class.

However, what makes Ueno Kai a headache is that Naruto's theoretical knowledge is simply a mess, and he is basically the king of the hanging department, and also, it is clear that the transformation technique and the stand-in technique are very fast to learn, but they don't know how to do the doppelganger technique at all.

No matter how Kei Ueno guides and how Naruto practices, there is no way to master it.

This led to the fact that the overall score, not to mention that Uchiha imp, there were several students in the class who were better than Naruto.

Every time he encounters the test of the doppelganger technique, Naruto always has to make a fool of himself, and he is the bottom in this regard, and Ueno Kei is helpless.

"Naruto !!!" Just when Ueno Kai frowned and was about to say something, a roaring voice sounded.

Naruto trembled, his face suddenly turned blue, and he was about to get up and run, but Ueno Kai showed a sinister smile, grabbed Naruto's collar with one hand, and grabbed Naruto's collar and pulled Naruto up.

Naruto, who is only 12 years old now, is only more than 1.4 meters tall, and it is easy for Ueno Kei to pull him up.

Naruto said with a panicked expression, "Brother Kai, let me go, hurry up, or the demon will come!" ”

Ueno Kai smiled slightly, silent, however, he gently put Naruto down, Naruto's face was happy, and he wanted to turn away, at this time, an eerie voice came from behind Naruto, "Naruto, who do you say is the demon?" ”

Naruto shuddered, a smile on his face that was more ugly than crying.

Turning his head slowly, "Yi ...... Iru ...... Teacher Iruka......"

I saw that what appeared in front of Naruto and Kei Ueno was a man wearing a Konoha Nakaya Shinobi or above costume, with an obvious scar on the bridge of his nose.

This man is none other than the head teacher of Naruto Uzumaki's class, Konoha Nakashinobu and Umino Iruka!

"Naruto, this is the first time you've skipped class? Well? You say, you failed the quiz last time! You dare to run away from my class! Iruka slammed his fist into Naruto Uzumaki's head and said through gritted teeth.

"Ouch" Naruto immediately held his head in his hands and squatted down, and Naruto's tears flowed out of his eyes, looking pitiful.

Ueno Kai smiled: "Naruto, the class still has to be taken well, every time, Iruka-sensei comes out to find you, and it will delay the time of other students!" ”

"Hey, I see." Naruto pursed his lips and said in a lengthened tone.

"Are you ......?" At this time, Iruka noticed Kai Ueno standing beside Naruto, not that Iruka, who was a middle ninja, was so vigilant, but in Konoha Village, there was no need to be so nervous.

Ueno Kai smiled slightly, he has grown very fast in the past three years, and there are so many students enrolled in school every year, and Iruka was not his homeroom teacher back then, so he couldn't recognize himself, which is understandable.

Kei Ueno smiled, "Iruka-sensei, I'm Kei Ueno, and I'm one year older than Naruto. ”

"Oh, so you're the one who graduated early!" Iruka had a look of sudden realization, as a teacher at the ninja school, there was a student who graduated from the ninja school ahead of schedule in three years, and Iruka still knew, although he didn't know the details, I heard that it was just because he was a genius, and all the school's courses had been completed.

Tell you about the students who can graduate early.

"Kei-kun, it's still in class, so I'll take Naruto back first." Iruka grabbed Naruto's shirt with one hand and said to Kei Ueno with a smile.

"Hmm." Kei Ueno said with a slight nod.

Immediately, he opened his mouth and said to Naruto: "Naruto, don't skip class, come back at night, Brother Kai show his hand!" ”

"Hey!" Naruto said listlessly.

Immediately, Iruka took Naruto Uzumaki and left the place and rushed back to the ninja school.

Kei Ueno shrugged his shoulders and returned to his residence to prepare dinner.

That day, at night, Naruto turned his grief and anger into appetite, and basically ate the food cooked by Kai Ueno, and it was thanks to Kei Ueno that he anticipated this situation and prepared some more meals, otherwise, I'm afraid, even his own dinner would be eaten up by Naruto.

The next day, on this day, Kei Ueno practiced at the training ground that Kei Ueno opened up next to the creek in the western suburbs of that year.

Kei Ueno's sword was placed diagonally on a nearby stake.

Kai Ueno quickly began to seal, ugly-mao-shen! The left hand is tightly pinched at the wrist of the right hand.

Whispered: "Rachel! ”

Suddenly, a sound similar to an electric shock sounded, and a dazzling white-blue light suddenly appeared in the palm of Ueno's right hand.

A powerful chakra aura!

Ueno Kei stared intently at the chakra in his right hand, and a trace of fine sweat broke out on his forehead.

However, after only a short while, the chakra in Ueno Kei's hand suddenly became violent, and Ueno Kei's face changed, and he wanted to do something.

The white light flashed, and with a "boom", the thunder light in Ueno Kai's hand suddenly exploded.

"Ahem." Ueno Kai fell to the ground, coughed lightly, then smiled bitterly, looked at his twitching right hand, and shook his head.

"Alas, Chidori has long been able to use it freely, but I didn't expect that it would be so difficult for Rachel's attribute nature to change, and my talent in the technique is really not very good." Kei Ueno muttered in a low voice.

Ueno Kai stood up and patted the dust on his body, and after a short while, his right hand stopped trembling, and Ueno Kai wanted to start practicing again.

At this time, Ueno Kei's face suddenly turned grim, and he said, "What's the matter?" ”

"Eagle, there is a mission!"

Kei Ueno nodded, and without hesitation, he put on his coat and gently pinned the sword to his waist.

With a flicker, he left the place.

After a while, Kei Ueno was dressed in the standard costume of the Konoha Dark Division, wearing a mask, and came to the gathering room of his team in the Dark Division.

PS: I slept too late yesterday and just woke up, so I'm sorry.
