Chapter 107: Learning Efficiency
The next morning at 6:00 AM:
“You're so hard to find,” Shisui said, looking at Kaida, who was lying on the ground, completely exhausted.
“Brother, you’re back! How was your mission?” Kaida asked while trying to stand up.
“Don’t you think this was a little excessive?” Shisui asked, helping Kaida sit.
“How long have you been here?” Kaida asked, circulating yang chakra through his body to aid recovery.
“Long enough to see you fighting 10 shadow clones alone,” Shisui said, shaking his head.
“I was trying to check my limits,” Kaida said shyly.
“And why weren’t you using the Sharingan?”
“Because I don’t want to be overly dependent on it. Initially, I used it while sparring, but when I tried sparring at the same difficulty without it, my efficiency dropped by four times,” Kaida explained.
“That just means that even an underdeveloped Sharingan enhances your efficiency by 400%. And the more you train with it, the better it’ll become. So don’t treat the Sharingan as a handicap,” Shisui said simply, sitting down beside him.
“Since the Sharingan increases my base efficiency, doesn’t that mean this kind of training is still beneficial for me?” Kaida asked.
“Of course. Normal training is crucial. Without a strong foundation, even the Mangekyo Sharingan won’t help you. I’m just saying you should also focus on training your Sharingan,” Shisui replied.
“Okay, brother. But why are you here this early?” Kaida asked.
“Oh! When I got home, I found Mom worried about someone’s well-being. So, being the responsible child I am, how could I rest? I had to find that ‘someone’ so Mom wouldn’t stress anymore,” Shisui said dramatically.
“But I already told Aunt that I’d be training using a soldier pill,” Kaida said doubtfully.
“And I’m an elite jonin strong enough to protect myself, yet she still worries every time I go on a mission. That’s just how moms are,” Shisui replied with a smile.
“Right,” Kaida said, remembering how his own mother visited him at the hospital every morning, despite his constant pleas for her to rest.
“So, I know you’re not ‘feeling hungry,’ but how about we head back for a quick bite?” Shisui suggested.
“Okay, brother,” Kaida agreed.
As they walked home, Kaida told Shisui about his meeting with Fugaku.
“You lucky brat! For that many Contribution points, some of us jonin have to stay away from the village for weeks, sometimes months. And you’re going to earn them so easily. The world truly is unfair,” Shisui said, shaking his head.
“Brother, I’ve been meaning to ask—are you saving Contribution points for something?”
“Yes, I originally wanted to buy an S-rank jutsu, but now I’m saving for medicine for my eyes,” Shisui said.
“Are you having trouble with your vision?” Kaida asked, concerned.
“Not yet, but I had to use my Mangekyo Sharingan during a few missions, so my vision’s starting to blur. The clan head said it’s treatable and should clear up soon, though he’s overcharging me for the medicine,” Shisui joked.
“Have you visited the hospital about it?” Kaida pressed.
“No, it’s not at a critical stage yet. I can still see better than a normal person. This is just a precaution to prevent problems down the line,” Shisui assured him.
“Are you sure? If you want, I can ask Sensei to check it out,” Kaida offered.
“You brat, I said I’m fine! Stop worrying,” Shisui said, flicking Kaida’s forehead.
“Okay,” Kaida said, rubbing his head.
By then, they had reached home and entered together.
“Mom, I brought him back,” Shisui called.
“Welcome back, Kaida. You’re going to eat breakfast, right? Then go take a bath first,” Hae said, wrinkling her nose at the smell of sweat from Kaida’s constant training.
“Yes, Aunt,” Kaida said and headed to his room.
After some time, they all sat down at the dining table.
“Hey, how come you decided to train alone without me?” Yomi asked when she saw Kaida.
“You’re already training hard, Yomi. How could you make time to train with me?” Kaida replied.
“Did you forget I’m not the only one training?” Yomi asked with a smirk.
“No, but I’ve exceeded my training schedule, so I can fit in more time for this,” Kaida said casually.
“Show off,” Yomi muttered, focusing on her food while thinking, *‘Just wait, I’ll catch up to you.’*
Kaida turned to Shisui and asked, “Brother, can we continue our genjutsu training after you rest, or do you have more missions?”
“Nope, I’m taking some time off. I already told the clan head before my last mission. We can continue your training after you’re back from the hospital,” Shisui replied.
“Just don’t overdo it,” Hae said, shaking her head.
After breakfast, Kaida and Yomi left for their respective destinations, while Shisui went to his room to get some much-needed sleep.

Kaida took a small detour to the training area.
*‘I could send shadow clones to the hospital for training... but that’d be disrespectful to Sensei. Still, I could use shadow clones to complete missions while I train there,’* Kaida thought.
He began making shadow clones, taking his time since he still had an hour and a half before he had to go to the hospital. After making 60 clones with 15% of his chakra each, he made a final clone with 50% of his chakra. His plan was simple: the stronger clone would retrieve missions from the clan headquarters, and the others would complete them quickly. Then he headed to the hospital.
…
Kaida arrived exactly on time. Mitsuru had instructed him to first learn the basics of treatment from a nurse and study the first-level medical books, along with perfecting the poison removal jutsu. His plan for the day was already set.
Kaida approached the receptionist and said, “Good morning, ma’am. Sensei said to arrange for someone to teach me the basics of treatment and to provide me with the first-level medical books.”
“Okay, just give me a minute,” the receptionist replied and went to take care of it.
A minute later, she returned with a middle-aged man and introduced him: “Kaida, this is the chief of all the medical nurses here. He’s agreed to teach you. Chief, this is Kaida Uchiha, Mitsuru-sama’s student.”
Kaida bowed and said, “Good morning, sir. I’m Kaida Uchiha, and I’ll be in your care.”
“Great. I’ll be making my rounds in 30 minutes. You can follow me today and learn by watching,” the chief said, then left, telling Kaida where his office was.
The receptionist added, “Since Mitsuru-sama has already booked a training room for you, I’ll send the books there so you can study them during your free time.”
“Thank you very much,” Kaida said and went to the room where he’d trained yesterday. There, he made 30 shadow clones. Half practiced the poison removal jutsu, while the others waited for the books. With this, Kaida had almost reached the maximum number of clones he could create.
Kaida then went to the chief’s office and followed him on his rounds for the rest of the day. He watched the chief perform various tasks like plastering, bandaging, administering medicine, and checking civilians with minor conditions.
Kaida learned a lot from him while his clones worked hard on their respective tasks.
