Chapter 41: Advanced Training (Part 2)
"Yes, Minato-sensei!"
When Koshino, using the app's accelerated training, quickly completed the Double Rasengan and Rasengan Throwing Technique training, the Fourth Hokage giving Koshino a way out was indeed a result Koshino wanted to see.
But who would have thought that the Fourth Hokage's new instruction for Koshino was to join Kakashi's Anbu squad and go on missions with Kakashi?
Then, when Koshino weakly nodded at the Fourth Hokage, agreeing to join Kakashi's Anbu squad, he suddenly felt that the trouble he was about to face had just gotten bigger.
Not to mention the numerous misunderstandings between Koshino and Kakashi, neither of them really thought highly of the other.
Just the thought of joining Kakashi's Anbu squad gave Koshino such an awkward feeling that he couldn't even focus on training.
However, since the Fourth Hokage had already made the decision, it wasn't something that Koshino or Kakashi could change.
Besides, the Fourth Hokage wanted Koshino to join Kakashi's Anbu for his own good. By gaining more combat experience during missions, Koshino's chances of survival on the battlefield would increase.
Of course, there was another reason the Fourth Hokage instructed Koshino to join Kakashi's Anbu squad.
He simply didn't have the time to guide Koshino and Kakashi in their training recently.
The reason for this traces back to Koshino's previous training with the Rasengan Throwing Technique!
Years ago, when Jiraiya hadn't left Konoha, the Fourth Hokage was inspired by the Tailed Beast Bomb to create a hand-sign-free jutsu.
After three years of effort and some guidance from his mentor Jiraiya, he finally completed the development of the A-rank jutsu Rasengan.
Unfortunately, at that time, the Fourth Hokage had only developed and mastered the Rasengan and hadn't simplified its training method.
It wasn't until recently, through correspondence with Jiraiya, that the Fourth Hokage and Jiraiya truly simplified the Rasengan training method. This led to the scene where the Fourth Hokage taught the Rasengan to Koshino and Kakashi.
However, during the process of simplifying the Rasengan training method, the Fourth Hokage and Jiraiya felt they had hit a bottleneck in the Rasengan's development.
Who would have thought that Koshino's Rasengan Double Shot and Rasengan Throwing Technique would suddenly enlighten the Fourth Hokage, giving him new ideas for advancing the Rasengan's development?
Undoubtedly, if the Fourth Hokage in the original storyline had lived longer, advanced Rasengan techniques like the Giant Rasengan and Wind Release: Rasenshuriken might have been developed earlier.
At this stage, the Fourth Hokage was inspired by Koshino and had new ideas for advanced Rasengan techniques. In a way, Koshino had altered the Fourth Hokage's life path.
Whether the future master of advanced Rasengan techniques would fall in the Nine-Tails incident had become an unknown.
Koshino, on the other hand, was completely unaware that his small actions had caused a ripple effect.
Upon learning that he was about to join Kakashi's Anbu squad, Koshino was filled with resentment and was determined not to suffer any losses in Kakashi's squad.
"Joining Kakashi's Anbu squad, where he has the seniority and is the squad leader, he's bound to give me a hard time."
"Sigh, if only Kakashi had the personality from the original storyline, but instead, he's someone who holds grudges."
"It seems that to avoid being troubled, I need to quickly improve my strength."
"Luckily, with the advanced Rasengan techniques and the accelerated training effect of the APP, my strength can improve rapidly!"
"Now that I've mastered the Rasengan Double Shot and Rasengan Throwing Technique, two techniques that can be considered finishing moves, I shouldn't be as embarrassed as before when facing Kakashi!"
Seeing Kakashi begin the second stage of Rasengan training under the Fourth Hokage's guidance, Koshino, with some free time before Kakashi introduced him to the other Anbu squad members, didn't hesitate to use the Multi Shadow Clone Jutsu to start training.
The Fourth Hokage and Kakashi, having long witnessed Koshino's talent in jutsu, were only slightly surprised to see him using shadow clones for training. They thought to themselves that Koshino's talent in jutsu was indeed extraordinary and continued their own training. Koshino, noticing their lack of surprise at his shadow clone training method, immediately directed his clones to train.
"Three shadow clones should be enough for training the Giant Rasengan. As long as it's added to the training progress bar, the APP can help me complete the training."
"As for the remaining three shadow clones..."
"Ha!"
"They'll focus on truly innovative Rasengan training!"
Thinking this, Koshino's eyes sparkled with determination, and he thought to himself:
"If I can use the Rasengan with just one finger, wouldn't that mean my chakra control training could reach a new level?"
"Great! I'll name this new jutsu Finger Rasengan!"
"Shadow clones, begin training!"
With the shadow clones starting their training, Koshino's main body didn't remain idle. He continued training in the Leaf Steel Fist style while wearing weights.
Soon, the sun was about to set.
Under the Fourth Hokage's personal guidance, Kakashi was also about to complete the second stage of Rasengan training and would begin the third and final stage the next day.
Some might wonder how Kakashi could progress so quickly in Rasengan training.
Well, Kakashi is a Jonin, capable of creating S-rank jutsu like the Lightning Cutter, with chakra control skills that are already outstanding.
Especially with the Fourth Hokage's personal guidance and the simplified Rasengan training, Kakashi quickly grasped the key to mastering the Rasengan. Not only was he about to complete the Rasengan training, but he also seemed to have found a way to reduce the Sharingan's chakra consumption.
However, despite Kakashi's rapid progress under the Fourth Hokage's guidance, Koshino's progress, even with the APP's help, was far beyond Kakashi's.
When Koshino's shadow clones disappeared, the Finger Rasengan and Giant Rasengan were both added to the training progress bar.
Then, with just a simple communication with the APP to adjust the training progress, Koshino mastered both advanced Rasengan techniques, further enhancing his strength.
After Koshino and Kakashi temporarily completed their training, the Fourth Hokage left early to focus on developing advanced Rasengan techniques.
Shortly after the Fourth Hokage's departure, as Koshino awkwardly restored his chakra in front of Kakashi, Kakashi glanced at him indifferently and said, "Koshino, you probably don't know the other Anbu members in our squad."
"When they arrive, I'll introduce them to you."
