After leaving Fugaku's office, Sora was in an exceptionally good mood. He couldn't stop grinning at the memory of the Clan Head's shocked expression upon seeing Kaida's sealing prowess.

"You should have seen the look on his face!" Sora exclaimed gleefully as they walked back home. "I don't think I've ever seen Fugaku-sama so surprised before."

Kaida chuckled, amused by his teacher's childlike enthusiasm. "I'm just glad I could meet his expectations. Though I have to admit,

I wouldn't have been able to learn so quickly without your guidance, Sensei."

Sora waved a dismissive hand.

"Nonsense, you're a prodigy. With or without me, you would have mastered the basics eventually." He shot Kaida a sly grin. "But I certainly helped speed things along, didn't I?"

"Yes, but Sensei, I don't have the contribution points or the money to pay you right now, so can I start my next part of the training after 2-3 months?

By then, I should be able to get that amount," Kaida asked.

Normally, he should have been able to pay the amount until the seal master level by now, but since he had invested all of his money,

Including what they had saved from completing all those missions with Yukihiro, Kaida was penniless at the moment.

He only had 200,000 contribution points for now due to completing so many D-rank missions for the last month.

Even though he could have chosen to start the business after some time, there were two reasons why he didn't.

Firstly, he himself didn't think that he would be able to complete the basics class within a month.

Secondly, there was actually no hurry for him to rush things too much, even though he needed to increase his strength. The Uchiha massacre would take 3-4 more years according to the normal timeline. If his strength keeps on increasing at the same rate,

Then Kaida will be at Kage level by then. So, there was no actual need to focus too much on training, especially when he could invest his money in something much more important.

"Huh! Are you dumb or something? I already told you the amount of money or contribution points you give to a fuinjutsu master is not much for him.

You are going to give me 3 million Ryo or something, right?" Sora asked after listening to Kaida's request.

"Yes, Sensei."

"I can easily earn that amount in 3-4 days, so you don't have to worry about paying me. Just give me the amount whenever you have it. We can continue our training as it is," Sora said.

"Thank you, Sensei," Kaida said, bowing a little.

Sora just waved his hand dismissively. After some time, they reached Sora's house.

"Since you have to learn many more seals to start learning the next level of fuinjutsu, we can't directly start your training. Just wait here; I have just the right thing for you," Sora said and went inside the house.

"Okay, Sensei," Kaida replied and just sat at the chair on the training platform. After some time, Sora came out of the house with a book in his hand.

"This is the book written by my father. It contains many seals perfect for beginners. You can continue learning seals from this book, and you can always come to me whenever you have any doubts," Sora said while giving that book to Kaida.

'This is the second book of the day. Is it my lucky day or something?' Kaida thought and then said, "Thank you, Sensei. I will take good care of it."

"Okay, since there is nothing more for me to do, I am going back to my study. You can practice on your own. If you encounter any doubts or problems, come and find me in the study," Sora said.

"Okay, Sensei," Kaida said and made 10 shadow clones to start training on different seals each.

Sora saw this and went back to his house. After training until 10 PM, Kaida went back to his house, ate dinner with his family, and then went to sleep.

From the next day, Mitsuru started teaching Kaida various advanced medical jutsu. This time, they were a little trickier, especially the Chakra Scalpel.

Cutting someone from the inside without damaging their skin or chakra pathway was extremely difficult for Kaida, but knowing the importance of the jutsu, Kaida paid special attention to learning it while also learning many seals at the same time. Doing this, two more months passed.

...

(At Konoha hospital)

"Sensei, I have finally learned the Chakra Scalpel jutsu completely," Kaida said.

"I have said this before too; there was no need to use that jutsu while moving. Your training was futile as it is not like you are going to use this jutsu for fighting. Since it is used during operations, why would you train for using it while moving?

I am still saying, don't use this jutsu during a fight; the level of precise control of chakra it will need is too high for you. Heck, even I could barely do it," Mitsuru said.

'This means Kabuto was already at the level of chief medical ninja during the Tsunade retrieval arc,' Kaida thought, but since he couldn't tell that he knew more about this jutsu's potential than Mitsuru herself, he just made up an excuse.

"This was the reason I was training for using the Chakra Scalpel while moving, since that will also improve my chakra control too."

"Well, it is your choice. With this, you could take the exam to become a specialist, but there is another condition to become a specialist which you have not fulfilled until now, so you will have to wait for a little more time before taking the exam."

"Which condition, Sensei?" Kaida asked.

"Before taking the exam for a specialist, a medical ninja should have a minimum of 6 months of experience as a general practitioner. Since you only have experience of 3 months, you have to continue treating patients for 3 more months before you can apply to take the specialist exam."

"That's great. According to Sora Sensei, I should be able to learn fuinjutsu to be barely considered a seal master. Then you can teach me the Mitotic Regeneration Jutsu, right?" Kaida asked.

"Kaida, it is not possible for you to become a Seal Master in just 6 months. That shit takes time..." Mitsuru stopped when she remembered how Kaida learned the basics of fuinjutsu in just a month.

sigh

"Okay, if you become a Seal Master by then, then we can definitely start your training in that jutsu, but I will say it once again. I don't know the complete jutsu, only Tsunade-sama does," Mitsuru said.

"Not even Grandpa knows that jutsu?" Kaida asked.

"No, he also only knows as much as I do. Since we don't have the complete version of that jutsu, we can only use it at 30% of its full efficiency," Mitsuru said.

'It makes sense. If Hiruzen knew about such a powerful jutsu, there should have been some ninja trained in this jutsu. This jutsu is way too useful to be forgotten in history,' Kaida thought and then said, "Then I would be happy to just learn that much, Sensei."

Mitsuru saw the smile on Kaida's face and sighed, 'This boy is way too dedicated and talented. I really hope he didn't die on some stupid missions he is so obsessed with,' Mitsuru thought, remembering how many geniuses she saw or heard dying on the battlefield.

"Okay, but be careful and don't bite more than you can chew," Mitsuru said.

"Thank you, Sensei," Kaida said and went out of the hospital. Since it was already 4 pm, after leaving the hospital, he directly went toward Sora's house...
