Kazuki's clone was in the library searching for some C-rank Jutsu while he was practicing kenjutsu with Akari.
After the training ended, Akari said, "Kazuki, Ryuma, from tomorrow onwards, I'll teach you chakra flow."
"Great. Kazuki said, "I read about it in a book. It'll be really useful in the Chunin exams." Kazuki replied.
"Yeah, if we master Chakra Flow we will become on the same level as Yuki." Ryuma said.
After the training was over, Kazuki went to Ichiraku with Yuki and Ryuma, then headed home, there he picked up the scroll in which his clone noted details about all the jutsu he has to master.
Then Kazuki went to the training ground and read the scroll. there were all the C-rank jutsu his clone had selected.
~Fire Release: Great Fireball Jutsu
~Fire Release: Phoenix Sage Fire Technique
~Fire Release: Dragon Fire Technique
~Fire Release: Fox Fire
~Fire Release: Flaming Hail
~Fire Release: Eruption
~Water Prison Technique
~Water Release: Starch Syrup Capturing Field
~Water Release: Wild Water Wave
~Wind Release: Great Breakthrough
~Wind Release: Gale Palm
~Earth Release: Hiding Like a Mole Technique
~Earth Release: Subterranean Voyage
~Earth Release: Tearing Earth Turning Palm
'Obviously I can't learn all these jutsu in just one month. these are all the C-rank jutsu I'm going to learn even after chunin exams.' He thought.
'The jutsu I'm going to learn in this one month are.'
~Fire Release: Dragon Fire Technique
~Fire Release: Fox Fire
~Fire Release: Eruption
~Water Release: Starch Syrup Capturing Field
~Wind Release: Gale Palm
~Earth Release: Hiding Like a Mole Technique
~Earth Release: Subterranean Voyage
He thought, 'Earth-style Jutsu are my priority, they will really help in that type of terrain but there's just one problem. Most people in the chunin exams will use Earth-style jutsu and Earth style is vulnerable to Lightning and guess what? I have 0 affinity towards Lightning!! I checked then with my mind's eye and my main affinity was obviously fire, 2nd was surprisingly water, 3rd was earth, and 4th was wind. Wind was pretty low as well. I wonder if I'll be able to copy lightning style with Sharingan once I unlock it?'
'So which jutsu should I start with? I think Hiding Like a Mole and Subterranean Voyage are the most important. First will allow me to go underground and Second to swim underground.' Kazuki thought.
Akari sent her shadow clone to train Yuki while she stayed with Kazuki and Ryuma.
"Alright, I think you already know the basics of Chakra flow but the books don't go into details, so listen carefully." Akari said.
Both of them paid attention.
"Chakra flow is a technique that allows you to flow chakra through any object, weapon or even body part." Akari said.
"Body parts?" Kazuki asked in confusion.
"Yes, even body parts. There have been many instances of flowing chakra in body parts to make them stronger. The most common example is a B-rank earth style jutsu called Iron Skin." Akari replied before making some hand signs.
'Earth Release: Iron Skin Jutsu.'
Her hand turned black, she slammed it on the ground, causing the earth below to crack and there wasn't even a single scratch on her fist.
"In this jutsu I flowed Earth style chakra in my hand to make it harder, increasing its defensive and offensive capabilities. The most skilled users of this technique can make their skins as hard as diamond. I am not a specialist but even I can make my skin as hard as steel," Akari said.
"The Fourth Raikage also uses this chakra flow for his lightning style chakra mode that greatly increases his defence and speed." She said.
Kazuki was surprised by this. He didn't know that chakra flow had uses other than in kenjutsu.
"However, we only have to focus on Chakra flow used on weapons for now. Lightning and wind are the most used chakra flows for swords. Fire is good too but there is one problem. Fire release damages the sword very easily. Lightning and wind also damage ordinary swords but that's very slowly. Fire style damages it very fast, so you might have to carry multiple swords with you, Kazuki, if you still want to go with fire release." Akari said.
Kazuki thought, 'Why do I have this bad luck? My affinity for wind and lightning is the weakest. I guess I'll have to carry multiple swords in my storage scrolls. Swords are so expensive but it's good that I saved a lot of money from the missions and selling storage scrolls anonymously using transformation jutsu but what did she mean by ordinary swords?.'
Kazuki said, "Yeah, I'll stick to Fire But sensei, what did you mean by ordinary swords"
"There are special types of swords called Chakra swords. These are made from a special type of chakra metal that not only doesn't get damaged by chakra flow but also gives more output than normal swords because it lets chakra flow into the sword smoothly without any resistance.
Kazuki's face lit up, and he asked, "Where can I buy it?"
"You'll have to order it, you can go to any blacksmith store for that but it's very expensive. I'm not sure if you'll be able to afford it."
"I'll check it out today, thanks." Kazuki replied
After that, Akari started teaching them Chakra flow. Kazuki was learning it faster than Ryuma, mainly because it's more of a Ninjutsu skill even though it's used in Kenjutsu.
After the class was over, the three of them headed home. Ryuma went the other way, where his home was, while Yuki and Kazuki were heading in the same direction.
"Yuki, I have to go that way." Kazuki said.
"But isn't your home this way?" Yuki asked.
"Yeah, but I have to buy a sword." Kazuki replied.
"What happened to your previous sword?" Yuki asked.
"I am learning chakra flow and Sensei said that I should buy a chakra blade to use chakra flow to its utmost potential." Kazuki replied.
"Why didn't you tell me? Don't you remember what Father said? The Senju clan will fund your training, which means paying for any equipment required for it."
"But a Chakra blade is very expensive." Kazuki insisted.
"Do you think the Senju Clan is poor?" Yuki said, looking a bit offended.
"Come with me," Yuki said before grabbing Kazuki's hand and leading him towards the Senju clan compound.
"Wah-" Kazuki was taken aback by her sudden action, and his cheeks flushed slightly.
[I don't think I can write large chapter while being consistant so for the next 3 months (until my exams are over), chapters will be 1000- 1200 words.]
