Naruto: Mixed Heritage(Rewrite)

"Now that we have already established your chakra field and its limit, we will move to the various ways we develop sensor nin in the village." Sato began.

"I won't delve deeper into the details, but I will give you a list of exercises that will help you become a decent sensory if you put in the work. We will only do two for now, but if you show promise maybe we can move to the more advanced techniques. Any questions before we begin?"

Renjiro shook his head as he understood the gist of things so far

"Great! The first exercise will test your perception." Sato said while he took some balls from a cabinet in the corner and placed them at targets with varying distances in the room.

"I want you to focus on the targets in front of you, activate your chakra field and tell me what you sense."

"Hmm, I think I feel something. It's like a gentle pulsation, rhythmic and steady." Renjiro answered.

"Good, that's the chakra flow within the target. Now, observe closely as I infuse it with more chakra. Notice any changes in intensity or pattern."

"It's brighter and more vibrant than before."

"Excellent observation. This exercise will help you notice even the most subtle chakra fluctuations, which will be essential for tasks such as identifying hidden threats, tracking targets, and analyzing chakra-based techniques during combat or espionage missions."

"Now let's move to the second exercise," Sato said as replaced the balls in the targets. 

If Renjiro had not activated his chakra field, he would not have been able to tell the difference between the two sets of balls. The newer set of balls had far little chakra, even before Sato's chakra infusion.

"This exercise is a chakra source localization one. We are going to rob you of your sight and smell senses by blindfolding you and placing a seal on you. You have to rely on your chakra field to pinpoint the targets. We'll first start with stationary targets."

Renjiro was handed a blindfold and the seals in the room were activated. Out of the three senses that Renjiro was left with, only hearing would be useful in the test, but that was untouched since Sato had to instruct him during the exercise.

"Are you ready?"

"Yes," Renjiro said. He was a bit uncomfortable as the situation was like sleeping with a cold but without the nasal congestion.

" Alright. Activate your chakra field and try sensing the targets."

'Even with my sight and smell, it would still be hard to sense the chakra in the targets.' Renjiro lamented while he activated his chakra field.

'The only chakra I can sense is Mine and Sato's.' The little chakra in the new set of targets made them hard to sense.

"Now, tell me the direction of the targets."

"I can sense one of the targets here, here and here." Renjiro pointed to his left, behind and above him.

'Three? He got three of them? It took me a whole week to even sense one despite having a larger chakra field at the same age.'

"Hoho three out of five on your first try? That's good work Renjiro. It seems that this is a bit too easy for you. Let's switch things up!" Sato said as he flared his chakra up. 

'Damn! Is that all his chakra? I want to be like that when I grow up. If that's the case, what about Naruto and other Jinchurikis?' Besides being suffocated by Sato's chakra, Renjiro was amazed by the display.

"Now try sensing the targets again."

Renjiro's brows furrowed as he tried to focus on the targets, but he couldn't. It was hard trying to sense objects with little chakra while someone was flaring his chakra right beside him. All his chakra field could pick up was Sato.

"It isn't as easy as before huh?" sato said as he saw the near bloated look on Renjiro's face. He then reigned in his chakra and removed the blindfold on Renjiro.

"You need to be able to perceive and differentiate the type of chakra that you want to sense. It might be hard now but I am sure with your potential you will soon get a hang of it. 

I won't always be free but you are free to come and use this room. If you have any questions, you can just ask any of the attendants available, I am sure they will help. That's it for today."

"Thank you for your guidance Sato-sensei."

"I look forward to your growth Renjiro. Don't disappoint me."

With those words, they went back to his where Miwa was waiting and after a bit of banter, they headed back home.

"Good Work!" Sato said with a tinge of elation evident in his voice.

'A week, while It's not bad, it is not good either. But I am sure he will still be an exceptional sensor. Konoha severely lacks sensors as only three clans have specialized in this. Having another sensor out of these clans would be good enough.'

Meanwhile, Renjiro could only sigh in relief. He placed his hands on his glabella massaging it. He hoped that it would lessen the mental fatigue that comes with activating his chakra field for a long time.

Renjiro had continued with his sensor training and if he could sum it up in one word it would be Frustration. It even made self-doubt creep in and Renjiro started wondering whether he was cut out for this or not.

It was only the boon from being a sensory ninja that pushed him through this. Sato, on the other hand, was also relieved. 

It had taken Renjiro a whole week to sense the targets with his Chakra field. It was so close to the deadline Sato had set for him as after that Sato had to return to his duties.

"Now we are going to keep altering the distances we place the objects, but since you've already sensed them, try zoning in on their chakra signatures and it will be fairly easy," Sato remarked.

Following Sato's instructions, it became relatively easier for Renjiro to sense the targets even when they were moving. He went from barely sensing them at all to now sensing them seven out of ten times by the end of their session.

'The upside is that My chakra field is like a muscle. The more I use it, the more it grows just like my chakra reserves. This can be attributed to the growth phase I am in. Hopefully, the decline rate is in the far, far future.' Renjiro thought.

His Chakra field had grown and was now twelve and a half meters wide(around forty-one feet).

After his session with Sato, Renjiro headed back to the clan as they had arranged a training exercise. It was more of a workshop where all the clan children, genin and academy students got together and competed.

The Uchiha clan compound was buzzing with activity as the clan children gathered for a special training workshop. The courtyard, surrounded by traditional Uchiha buildings, echoed with the enthusiastic chatter of young ninjas eager to hone their skills. 

Renjiro, dressed in a distinctive all-black attire, made his way through the crowd. The workshop, organized by the clan leaders, aimed to foster a sense of unity among the Uchiha young ones while providing them with a platform to share and refine their abilities. 

The main focus of course would be refining their Taijutsu and Sharingan, for those who awakened it of course.

It was through this that Renjiro got to meet his upperclassmen in the clan. He was shocked to learn of their identities as he remembered them from the anime. They were Inabi, Yashiro and Tekka.

'At least now I know how I will be when the anime events finally start.' Renjiro mused.

Renjiro joined the sparring area, where Uchiha children engaged in friendly but intense bouts of taijutsu. 

It did not take long before Renjiro found Kaito spectating a bout between some genins. 

Noticing Renjiro, Kaito made his way towards him. Renjiro raised his brow when he saw this as they were not well acquainted.

"Oi Renjiro, let's spar," Kaito said with a dramatic flair that only seemed to exist in his head.

'So that's what he wanted.'
