After completing all of his missions, Kaida and Minoru grouped all of the remaining 40 bandits at the first bandit's base.
"You guys will stay here until we make some arrangements for you," Minoru said to them, while Kaida made a 2-meter-long wall all around the base 'for their protection,' not because he wanted to make sure that they would not run away while they were gone.
Well, it was just some extra precaution because according to Minoru, even if by one in a million chance these bandits could regain their memories back, that would happen after 1-2 years at the very least. Heck, even with the help of medical professionals, regaining their memories would be hard.
After making all the necessary preparations, Kaida and Minoru went back to the base. They both were waiting in the same first room in which they were before going out.
When they returned, Kaida found that this room now had a big bed, a cabinet full of books, and a study chair and table.
Kaida looked toward Minoru, wanting to know the explanation.
"What, did you think that I would let my grandchild sit on a sofa all day, waiting for his brother? Even though I can't allow you inside the base without the clan head's permission, I am still in charge of this base. Making your stay a bit more comfortable is not that hard for me," Minoru said.
"Thank you, Grandpa," Kaida said with an ear-to-ear smile on his face.
"It's all right, now go and take some rest. I have to check on some things," Minoru said and went inside the hidden base.
'I wonder what they are hiding inside that they can't even allow allies to enter the base,' Kaida thought, finding it ridiculous how he couldn't even enter the base when he had done so much for the clan. But then he remembered something.
"This is the real world, not some anime a kid can watch. There are many dark things happening in this world which I didn't know from the anime. So, the Uchiha, being a clan older than Konoha itself, may not be very clean, too. They must be doing something like that here which could not be shared even with the clan members, as they may not handle the knowledge well," Kaida thought.
Then, to pass his time, he started looking for books in the cabinet because he could not take a rest even if he wanted to. He had already eaten a soldier pill and had to stay awake for a total of three days, with 2 more days remaining. Kaida was full of energy at the moment, which was very awkward for his body because even though he was physically full of energy, mentally, he was super exhausted.
With the events he had faced in just a single day, like facing 7 root ninjas who were after his life, knowing about the Uchiha hidden base and his grandpa, completing 4 missions while reading some of the worst memories of his life, this had taken a toll on Hiruzen's mind. But since he could not sleep due to the effect of the soldier pill, Kaida decided to do the second-best thing which would help him calm his mind: reading books.
Even in his previous life, due to his medical condition, he couldn't do many things like normal children, so to pass his time, he started reading books from an early age of 6 years. Due to which by the age of 13, he came to like reading books so much that he started reading for more than 12 hours a day, even when he was admitted to the hospital.
That's why even in this world, Kaida read so much. When he picked up a book about genjutsu, since he had already read all the books about genjutsu from the village library as well as from the Uchiha library too, at least those he was allowed to read. But when he opened the book, he was once again surprised. This was not a normal book but a type of diary written by a jonin about his daily findings about genjutsu, how he trained, which type of mistakes he made, what he could have done better in his early days to improve his genjutsu.
Even though the name of this ninja was not famous, getting this type of knowledge was luckier than finding a box filled with gold. The complete life experience of someone, their achievements, mistakes, and possible ideas may literally save days or even months of Kaida's hard work.
So without wasting any more time, Kaida began reading that book. After completing it once, he reread that book twice, thrice.
When he was rereading the book the second time, Minoru came out of the base to check on him, but seeing how concentrated Kaida was, he didn't disturb him.
After reading the book four times, Kaida closed the book and decided to check the other books as well.The other books, though interesting, were not as good as the first one, mainly because they didn't contain something completely new which Kaida already didn't know.
Some of them were about various tactics one could use in a war, others were about how a single jutsu could be used in multiple ways, while others covered other basic topics.
So after skimming through all the other books, Kaida once again went back to the first book, trying to completely understand each and every word of that book.
"I think this much should be enough, my boy. It has already been 10 hours since you started reading books. I asked you to take a little rest, not to overexert yourself more," Minoru said, entering the room.
"I am kind of taking a rest, Grandpa. Reading is a very calming exercise for me. Oh! Grandpa, do you know the person who wrote this book?" Kaida asked.
"Not personally. This book was written by a ninja who died in the first great ninja war. From what I know, he was very proficient in genjutsu and kenjutsu, one of the most deadly combinations to exist. There is a story about how a team of 50 ninjas was assembled just to ambush him on his way back after completing an A-rank mission, and before dying, he killed 40 ninjas of that team," Minoru said.
"That is so awesome," Kaida said, picturing that scene in his mind, how cool such a death would be. But it was not like he wanted to have such a death, but it could be at second place on his list about how he wanted to die. The first one being death from old age, after a happy and fulfilling life.
(A.N: I personally like the second option more, such a death will be something people will remember even after many years of your death.)
But after thinking for some time, Kaida asked, "But Grandpa, if he was that great, why is he not famous in our village?"
"Because he was an Uchiha, and at that time, Tobirama was our Hokage. Since he didn't actually have a positive image of the Uchiha clan, the achievements of the Uchiha clan were not publicized at that time, so that our clan would not gain fame from their achievements in the war," Minoru said.
