Chapter 220: Jealous elders
Shisui was normally smiling at the result. He knew about Kaida's strength the best, and since he was friends with Itachi too, Shisui had quite a good idea about his strength as well. He was still happy that his brother was able to hold his own for so long.
One of the elders turned to Itachi and asked, "Didn't you say that his Sharingan evolved to 3-tomoe just one month before this?"
"Yes, elder. I was the one who helped him with that," Shisui replied.
"How could he stabilize and be so proficient so soon then?" the elder asked.
His doubt was genuine. In this world, nothing was for free; every power has to be earned. You may be lucky in one aspect, but you have to compensate for that luck. The 3-tomoe Sharingan gives its user quite a huge boost in power, along with an increase in chakra reserves too. But as a result, the mind-body coordination becomes very bad, almost like you are controlling someone else's body. Due to this, the fighting capabilities of a ninja actually degrade after getting the 3-tomoe Sharingan, at least until they can regain their body balance.
And Kaida not only regained that in one month but was already using his Sharingan with quite proficiency.
"Uncle, I think you are forgetting who his father was," Fugaku said.
Then every elder remembered that the boy in front of them was not only an Uchiha but a Senju as well. Every elder felt a bit of jealousy toward that boy; he actually got the best of both worlds.
Even though Uchiha were very proficient in everything and were superior in many fields compared to other clans, a strong body is something they never had (normally). Those with strong bodies and huge chakra reserves are usually born with them.
If not for the Sharingan increasing their chakra reserves each time it evolved, they might not be able to match a Senju on the battlefield (A.N: As no matter how fast a car is, if it runs out of fuel every 100 meters, it could never win a race).
But this boy doesn't have that problem. Suddenly, they had a very uneasy thought in their minds. They turned to Shisui, then Kaida, then once again Shisui.
Shisui understood what they were thinking and said, "You can directly ask him, elder."
One of the elders stood up and called Kaida.
"Yes, elder?" Kaida asked after coming in front of him.
"Kaida, I want to see your chakra reserve."
Kaida turned to Shisui, who just shook his head, meaning he could do whatever he wanted. It was also Fugaku's idea to check whether Kaida trusted them or not.
Kaida just nodded his head and stopped masking his chakra. Seeing the amount of chakra Kaida had, every elder felt a small heartache.
"You are saying this boy is just 9 years old? He already has more chakra than I had when I was in my prime," the elder who asked Kaida to check the chakra said.
Kaida just smiled awkwardly at that. Before he could say anything, Fugaku asked, "Kaida, did your chakra reserve increase when your Sharingan evolved to 3-tomoe?"
Kaida just nodded his head.
"A normal ninja has a 4-5 times increase in their chakra reserve. Did you have the same amount of increase?" Fugaku decided to share some of the details as well. He didn't want to make it sound like some sort of interrogation.
Kaida's face became a little sour, and he said, "Not at all. I only got a 2.5 times increase," Kaida said, like someone who had been deeply scammed.
After hearing that, every elder had to stop themselves from beating this ungrateful brat. He was already in the top 10 people in the Uchiha clan according to the amount of chakra he possessed, and he was still not satisfied with the amount.
But after their initial jealousy, they focused on the meaning behind Kaida's answer.
'It looks like when both genes combined, they both got a little toned down. He gets a strong body, but not as strong as a pure Senju, and his Sharingan is also not providing him the same enhancement as it does to any normal Uchiha. But the strength of his Sharingan is not weak at all; it even feels a little stronger.'
They deduced many things from a single fight. Though they still didn't know everything about Kaida, Shisui was not going to allow them to do so anyway.
Every ninja hides their true strength and never shows all their cards until they fight a life-and-death battle; otherwise, building a counter against you would be child's play for your enemy.
Unlike the elders and Fugaku, Mikoto and Hae didn't care about the boring stuff. They were just excited about the spar and relieved that none of their children got injured. Though they had some light injuries, these types of injuries were not even worth mentioning for a ninja.
But Kaida still went back to Itachi and offered to heal the injuries he had caused.
"Please, do I have to remove my shirt?" Itachi said with a smile.
"And give those girls a chance to feast on your body? If you want to show off, please use another time," Kaida said and healed Itachi's injuries in a minute.
Kaida was not very silent when he said that, and everyone smiled a little hearing that. Those kunoichi turned their heads, acting like they were talking about something else and were not watching the spar at all.
Itachi just sighed; it was not the first time he was in this situation. But with time, he had come to ignore those girls like air.
"You are good, but I will catch up in no time," Kaida said after healing Itachi back to his perfect condition.
"And you think I would be waiting for you to catch up?" Itachi said with an amused smile.
"You don't have to. I'm sure my speed is higher than yours. I will overtake you in no time," Kaida said.
"Hahaha, it's good to have dreams. But you should know, I have not even used 20 percent of my full strength," Itachi said. Not to demotivate Kaida but to give him the bigger and actual goal to strive for.
"How much percent did I use? 30? 40? No, I think 50%?" Kaida said.
"You are just 3 times more powerful than me. I will catch up in no time," Kaida continued, a fire burning in his heart. Until now, he kept thinking people like Shisui and Itachi were out of his reach. But after today's spar, the gap actually didn't seem that big.
Since the spar was over, Kaida turned to the elders and Fugaku and asked, "Fugaku-sama, I have a class to attend at the hospital. Can I go now?"
"Yes, you can," Fugaku said, and the elders nodded their heads.
Since the spar was over, Kaida turned to the elders and Fugaku and asked, "Fugaku-sama, I have a class to attend at the hospital. Can I go now?"
"Yes, you can," Fugaku said, and the elders nodded their heads.
Hearing that, Kaida bowed his head and quickly used the Body Flicker Jutsu to go to the hospital. He had become a general practitioner some time ago and had also learned all the advanced jutsu, especially poison creation and cures, as well as the chakra scalpel. In these two areas, he could already be considered an expert.
Okay, maybe poison creation could be excluded from this, but the chakra scalpel was something he took pride in. The only other person who would be this good at this jutsu is still under Konoha, and he has not yet become the future villain. Also, he hasn't gotten the extra resources he would have received if he had joined Orochimaru.
But now, things have changed. Konoha will focus on him more than Orochimaru would have, so in the future, Kabuto may become much stronger than an elite Jonin and might even reach Kage level.
But that is the future; for now, Kaida's mind was focused on one thing: increasing his strength. After today's spar, that feeling had only intensified. Not only is the future unpredictable, but the strength gap between him and the top ninjas is also very wide—but achievable.
And the fastest way for Kaida to increase his strength for now is...
'Mitotic Regeneration Jutsu, I have to learn it now,' Kaida thought as he reached the hospital.
He directly went toward Mitsuru's office.
"Sensei," Kaida said, knocking at the door.
"Come in," Mitsuru said.
"So you finally got time for learning? I thought you would still be busy showing off your strength," Mitsuru asked, a little anger visible on her face.
"What do you mean, showing off my strength, Sensei? I lost the spar. Heck, I lost when the other party was holding back more than three-quarters of his strength," Kaida said, a little dejected.
"Were you fighting an elder?" Mitsuru asked. She knew how strong Kaida was—he was already a Jonin-ranked ninja. Though not very experienced, he still had a huge chakra reserve to compensate for the lack of experience.
"Elder? He was just one year older than me," Kaida said.
"This is your last chance. If you don't give me a straight answer, forget about going back home for the next two days. You will be learning about various medical techniques for two days and nights straight," Mitsuru warned.
"Well, I don't think that is a punishment. Also, I'm sure by now you would have already guessed who my opponent was," Kaida said with a light chuckle. He was not a fool who would underestimate the intelligence of someone from the Nara clan.
"So you really fought against Itachi Uchiha. I've heard quite a few things about him. So, how long were you able to hold out against him?" Mitsuru asked.
"Not much. We fought using only kenjutsu and genjutsu, and even then, I was only able to hold out for 10 minutes before losing," Kaida said meekly.
"Itachi is a genius of the century. It would be a feat in itself for someone two years older than him to match him, while you are actually younger than him. Don't think too much about the loss; try to think about how you can improve yourself," Mitsuru said.
"I was about to ask you about that, Sensei. I have already learned all of the jutsu you asked me to. My operation success rate is also 100%. I have already crossed beginner-level fuinjutsu and will start learning seal master-level techniques in 2-3 days," Kaida said.
"You still haven't forgotten about that jutsu?" Mitsuru asked.
"How could I forget about that jutsu, Sensei? It is one of the signature jutsu of a legendary Sannin," Kaida said.
"But I have already told you, no one knows the advanced version of that jutsu except Lady Tsunade. What we know is one level inferior to that," Mitsuru said.
"That will be enough, Sensei," Kaida said with a smile.
"Huh, looks like you won't change your mind until I tell you the reality of that jutsu. Fine, listen.
The Mitotic Regeneration Jutsu, also known as the Strength of a Hundred Seal, allows the user to instantly heal any injuries they sustain during battle by accelerating their cellular regeneration. It also increases the strength of a person multiple times. But there are many drawbacks to this jutsu. The first and most significant one is accelerated aging and a shortened lifespan. The technique rapidly accelerates cellular division to heal injuries, which can significantly shorten the user's lifespan if overused. Each time the cells divide, the user edges closer to their biological limit," Mitsuru explained.
"I think that is not a bad thing, Sensei. If an injury could take someone's life, isn't it better to lose some years and save yourself?" Kaida asked. He was not that affected by this news, as he already knew about this side effect.
"You are underestimating it, Kaida. Even though Lady Tsunade improved the jutsu to make it useful, the version we have is highly unstable. If activated for 10 minutes, you will lose 1 month of your life, and that effect multiplies. After 20 minutes, you will lose 6 months; half an hour, and you will lose 1 year; and for 1 hour, 10 years of your life. In short, you would be killing yourself every time you activate this jutsu. Also, every time you heal any injury, you will lose another part of your lifespan," Mitsuru said.
"What about Lady Tsunade? How much time does she lose?" Kaida asked.
"One hour—6 months," Mitsuru said with a shrug of her shoulders.
'No wonder she is known as the best medical ninja in the world. She has almost removed the shortcomings of this jutsu. Sadly, I cannot wait for her to learn this jutsu. Heck, I don't even know what will happen in the next five years, let alone wait for 10 years for her to return. I will learn this version for now and modify it when I meet Tsunade in the future,' Kaida thought.
(A.N: Tsunade returns after the Hokage's death, which was when Naruto was 13-14 years old.)
"I still want to learn this jutsu, Sensei," Kaida said.
"Huh, you are too stubborn for your own good. Fine, for the next month, I will teach you everything you need to know before learning this jutsu. As for fuinjutsu, I will tell you the concepts you need to master. Learn them, and we will start the process for you to learn that jutsu," Mitsuru said.
"Thank you, Sensei! You are the best," Kaida said with a wide smile. Mitsuru just nodded her head with a smile and gestured for Kaida to leave. Kaida bowed his head and left the office.
'Oh, I forgot to tell him about the pain part. Well, let it be a surprise for him,' Mitsuru thought with a villain-like smirk on her face. (A.N: Just villain-like, not an actual villain 😉)
Kaida was re-reading some of the books when a nurse came to him.
"Kaida, Mitsuru-sama is calling you in room number 44," she said. Kaida nodded his head and said,
"Okay, I will go now." Normally, the nurse would have to give Kaida the same respect as any specialist, as he was a personal student of Mitsuru herself. But when Kaida heard someone thrice his age calling him "Kaida-sama," he firmly refused and insisted everyone call him by his name. Everyone was actually happy that their new boss was going to be such a humble person.
According to everyone, Kaida was going to succeed Mitsuru as the head of the Emergency Response Department for sure.
Kaida went to room number 44, where he once again saw a familiar scene in front of him. Mitsuru was standing in front of a stretcher, which was covered by a white cloth.
"Sensei, are we once again going to practice on a corpse?" Kaida asked.
Mitsuru smiled and pulled the cover off the body, and Kaida was a little shocked. The person was very much alive and horrified, his hands, legs, and waist tied to the stretcher. Even his mouth was gagged so that he could not make any sound.
