yoriichi was very less interested in academic studies as he knew almost everything he needed to know, except the history, geography and politics of this world. Here chakra helps in everything! If you study enough you can get a photographic memory.
Most people use chakra to fight because that's where their minds are stuck, you can use chakra More easily, and instinctively and you can do meaningful things. I don't have any royal relations to any country but have a very minuscule amount of king aura (purple-coloured aura) it cannot be sensed but it keeps everyone away from me instinctively.
If you ask me how I got this aura, it's probably the 'Hanafuda earrings'. It's passed down through generations and now I have it. It looks cool on me and I don't mind having fewer people around me. I bunk the class and the teacher doesn't say anything. Yes! It's the same as Iruka Sensei. He is a chunin and a bit strong and a civilian so the king's aura works more on him. I come to the river where almost everyone comes so I go near the forest to keep my training a bit secretive.
I take the wooden sword and start Swinging it while doing the water breathing. Forward Slash, vertical Slash, horizontal Slash, stab, I keep repeating it a thousand times. My body has bigger limits than normal people but unlike Naruto, I don't have large chakra so the breathing style compensates for my stamina. Water breathing burns less stamina and so I started taking in large volumes of air in a flow like water. I felt refreshed like I was inside the water.
I kept Swinging and after some time I ran out of chakra at the 800th swing. I did the remaining Swing with just a strong will and breathing technique, and my foundation was open for work "Becoming strong isn't easy eh" is what escaped my mouth, I was completely exhausted of chakra and stamina I broke down almost all the unnecessary fat.
I sat close to a tee and used breathing to store some chakra and stamina. Chakra is a potent form of human's physical energy and soul energy. So if I use breathing. I can use all the energy to the essence of my physical and spiritual energy until it is completely exhausted if I wish to do so. And reverse is also possible if I know and wish to do so. I felt that by breathing I could take in a very minimum amount of nature chakra which is not usable as it's very little to even feel. But I can absorb it to strengthen my chakra path and lungs or restore my chakra from trees.
' if I can sense the chakra of the tree then maybe I can use wood release?' having such unreal dreams I tried adding chakra to the tree only to destroy it. " I thought like ' finally I can have something as OP as sharingan but the Buble of dream popped very quickly" 'but thinking against.. why can I only sense nature energy in trees and not air or ground? Is it because I'm using breathing so it's sync with its energy or something?'
After getting my chakra at full capacity I used a shadow clone technique. How? You ask.. I just had my parents and I had it. It's not the forbidden ' multi shadow clone jutsu ' but just the shadow clone jutsu for my taijutsu. I have thought it through! I would be using beast breathing when using taijutsu with the chakra of the (hunter x hunter) style. Because I don't know anything else about taijutsu. And I need a clone because I need a shadow to completely master it from instincts to the natural movement of the body.
The taijutsu I know is completely based on defence so I will use it when I don't have a sword which means It would probably be my dead card. In this taijutsu, the person first redirects the opponent's attack in a way which makes him completely defenceless for a split second and that would be the window for a fatal attack. The attack would land on the points where it's very dangerous if the attack even landed once like the heart, liver, testicles, neck, chin, ankles, elbow, third spine bone, core, fingers or eyes it would just be the end of the shinobi dreams. Yes, it's a killing defence!
This technique needs high-level instincts and prediction of opponents' movements to the point where you should be able to fight with eyes closed. It will help in survival when sleeping in the forest. And even keep my battle intent trained.
I practised for an hour as that was my chakra limit after 3 refills I could understand how hard Lee trained when he didn't even have what I currently have. Most of his practices wouldn't have been fruitful, they created a very difficult character. I don't think I would have continued my training when I didn't get back anything for my training. If I had half of his determination I would be a jounin before 10 and would beat Itachi without sharingan.
I thought about my dream, what should I become? A Hokage? That's too common for a goal.. the best blacksmith in the world sounds good and I also have chakra to accomplish it. I can also become the best swordsman in the world easily till the age of 10 but what then? I don't have an ultimate dream to push me forward or a rival like Naruto has to push forward together.. become immortal? It's more of a curse! I later ignored it as it was the best solution for now.
'I had understood a few forms, especially the first form but understanding and doing it is different... it took a total of 3 months to complete the first perfect form and yes I was cutting a boulder with the sword without chakra and yes it worked!' While Yoriichi was practicing the sword someone saw him cutting the boulder with a sword which he didn't sense. It was shisui uchiha.
Shisui said this to Itachi as it was shocking for him to cut a boulder with a sword without chakra. Itachi and shisui went back to check the boulder and Itachi checked it and it was indeed cut without chakra ' how can a 6 year old cut a boulder without using chakra? If he could cut it with chakra it would be less shocking but this seems almost impossible to cut without chakra..' they were interested but not enough to spy on a kid half their age. King's aura also worked idk how but it will remain a secret.
( And why am I adding them in here? Because I want to change something in the original, Itachi will not kill the kids. Why? You ask.. I have more moral than the Naruto author to not kill them. Not that I have any other answers)
