Chapter 236: I will do it
Due to focusing too much on fuinjutsu, Kaida hadn't eaten well in three days and had been relying on soldier pills. That's why, when he finally returned home, he ate enough food to feed ten people before heading straight to bed—but not before telling everyone how happy he was about completing all his preparations and how he was going to learn the best medical jutsu soon.
Obviously, everyone else in the family was happy too. Kaida had taken four days off from the hospital, and one more day remained. Due to all the growth he had experienced in recent months, the amount of sleep he usually needed had decreased to 16 hours.
So, when Kaida went to sleep, he thought he would have 10+ hours before the hospital opened. But there was one thing he had severely underestimated: the mental fatigue he had accumulated over the last three days came crashing down on him, and he ended up sleeping for more than 26 hours. Even when he woke up, he was still feeling a slight headache.
'No wonder not many people use shadow clones to learn things; this method is too mentally exhausting for learning fuinjutsu. I don't even want to think about how much worse the pain would have been without the 3-tomoe Sharingan,' Kaida thought as he came out of his room and went to the kitchen, only to grab a glass of milk before heading straight toward the door.
"Young man, shouldn't you at least inform us before leaving?" Hae said from the hall, where she, Naruto, and Shisui were sitting.
"Sorry, Aunt, I forgot," Kaida said.
"No problem. Best of luck with learning that regeneration or something jutsu," Hae said with a smile.
"Thanks, Aunt," Kaida replied.
"Best of luck, brother," Naruto added, even though he didn't know why he was saying that.
"Thanks, bro," Kaida said, ruffling Naruto's hair a little.
"Now you can run," Shisui said, waving his hand in a shooing gesture.
Kaida just nodded after looking at the clock and went directly to the hospital.
…
Knock, knock
"Come in."
"Good morning, Sensei," Kaida said meekly, entering Mitsuru's office.
"Barely. It's almost noon. You're getting quite relaxed now, aren't you?" Mitsuru said, looking up from the book she was reading.
"I'm sorry, I just woke up. This time the effects of the soldier pills were too severe. I'm still having a mild headache," Kaida said.
"It's not the effect of the soldier pills, you brat; it's your masochistic training that's at fault," Mitsuru said like a big, angry, but caring sister scolding her little brother.
"I… I'm sorry, Sensei," Kaida wanted to refuse, but even he knew it was true.
"So, how was the result of your training?" Mitsuru asked, changing the topic.
"It was great, Sensei. I finally mastered all the seals you told me to learn," Kaida said.
"Show me the last one, then," Mitsuru said.
Kaida wasted no time and quickly took out his fuinjutsu set to start crafting the array. In just three minutes, Kaida made a near-perfect replica of what Sora had taught him.
"I don't want to see this, brat. Make the one you created yourself," Mitsuru said, dismissing the array because she knew there was no way Kaida could have made such a refined version so early—even a once-in-a-century genius of fuinjutsu wouldn't be able to do that.
Kaida just nodded his head and started making the version he had designed. If the previous version of the array was like freshly bought earphones, then this version was like earphones that just came out of a pocket—a jumbled mess.
Even though both were basically the same, it would be very awkward to use those jumbled earphones, right?
When Mitsuru saw the version Kaida had made himself, she nodded her head in approval.
"So, you finally did it. I was actually hoping that you would stop this absurd idea midway since the requirements are just too difficult, but you actually did it. So, I'll keep my word and teach you the Mitotic Regeneration Jutsu. That will cost you 15 million ryo, though."
"WHAT?" Kaida suddenly shouted after hearing the last part.
"Sensei, that much money is enough to issue two low S-Rank missions! Aren't you expecting too much from your poor student?"
"I'm not asking for that money for myself, brat. We'll need the help of two fuinjutsu grandmasters during the process—and not just any fuinjutsu grandmasters, but ones who have enough experience in the medical field too. In Konoha, there are only three such grandmasters, including Lord Third, but we can only count on the other two. Usually, they wouldn't help anyone even if you had money. Lucky for you, I know them personally and can ask them to help you. And you think they should help you for free?" Mitsuru asked.
"But, Sensei, where would I get 15 million ryo from…? Please give me a loan," Kaida said, bowing 90 degrees.
"Brat, that bathhouse of yours is already earning you tens of millions of ryo each month. Just take out some money from that stash of yours," Mitsuru said, as if she were talking to some cheap landlord.
Kaida's mouth opened and closed a few times—he had actually forgotten about that completely.
"Okay, Sensei, I'll ask Aunt Hae about this, but I'm sure she'll agree."
"Okay then, now let me tell you what kind of deep and profound bullsh*t trouble you've gotten yourself into. That jutsu you're trying to learn is not a single jutsu but a collection of three jutsu together.
The first one is the Strength of a Hundred Seal. This seal stores a small amount of your chakra daily, and a very precise and delicate chakra control is needed for this seal—by both the one who is making the seal and the one on whom the seal is being made. This is also the seal the fuinjutsu grandmasters will make on your body.
The second is Yin Seal Release. This will release the chakra stored in the first seal. Seal marks will cover your body, providing you with chakra to heal yourself. This will also be done with the grandmasters' help, but you will play a major role in the process.
And lastly, Creation Rebirth—a jutsu created by Lady Tsunade herself. This jutsu uses a very large amount of chakra but has the capability to heal any injury, no matter how lethal. One could say you'll become semi-immortal after you activate this jutsu. But this is the most gruesome part, and the final chance for you to back down one last time," Mitsuru said.

"In this part, you'll have to suffer injuries to each part of your body and then heal those injuries yourself. The healing seal will be made to perform that same thing once chakra is provided, so during battle, healing will become automatic. But you'll have to heal yourself while feeling the pain of various injuries to get the actual method of healing since, during a fight, you WILL feel pain from your injuries. So we can't risk giving you painkillers," Mitsuru continued.
'That is just pure torture—inflict all types of wounds on yourself, your muscles, bones, tendons, lungs, liver, heart… and the list goes on. I may die from the pain,' Kaida thought.
Mitsuru saw the fear in Kaida's eyes, and that was a perfectly natural response. Even the thought of getting all those injuries is enough to cause fear in the heart of any living being. But to Mitsuru's surprise, Kaida's eyes regained their resolve very soon.
"I'll do it, Sensei," Kaida said, while his thoughts were, 'I've invested too much time in this to back off now just because of some temporary pain. I can surely bear this much pain,' not knowing how wrong these thoughts were.
