Naruto: My Ninjutsu is mediocre

Senju Tobirama stared at Yuzhen's left hand for a while, then shook his head in disappointment, but it was obvious that he was very interested in the development of this new ninjutsu.

As we all know, Tobirama Senju was the greatest, most imaginative and most eccentric inventor before Orochimaru. Exploring the development of new ninjutsu is definitely his excitement.

"To realize the power of this ninjutsu, three conditions are required, namely high-density chakra, extreme energy compression, and super-speed spin. Now it is difficult for me to achieve these three conditions at the same time." Yu Zhen said.

His chakra wasn't up to par before, but now he can try again.

Naruto Uzumaki of the Konoha era, as the most famous master of hand-rolled balls in history, made unimaginable contributions to the development of the Rasengan ninjutsu.

It is precisely because of Naruto's "stupid method" that the difficulty of learning the Super A-level Rasengan has been reduced to below B, because he creatively added shadow clones when using the Rasengan.

When using the sealless ninjutsu, you have to make hand seals first. It is hard to say whether this is the evolution or degeneration of the Rasengan. It can only be said that Naruto's thinking is very clear.

"Of course, this technique aims to be performed instantly with one hand, as this is the most practical. However, when learning it separately, you don't need to be so strict. First, develop the technique, and then consider practical application."

As he spoke, Yu Zhen covered his left hand with his right hand, and then he saw the loose chakra compressed towards the center of both hands little by little, and finally gathered into a small light blue ball.

It really looks a bit like a Rasengan? Unfortunately, it's just a facade, as this chakra ball is static.

"One hand maintains the energy release, and the other hand maintains the shape change. Unfortunately, I don't have a third hand." Yu Zhen's tone was full of regret.

Senju Tobirama reacted quickly, he had learned to answer quickly: "The third hand? How about the clone technique?"

"I come from a small ninja clan that lacks inheritance, and I don't know the physical clone technique."

"I……"

Senju Tobirama almost blurted out the words "I will", but before he said it, he stopped the impulse.

Because he found that he seemed to have been tricked again.

Chapter 21 Rasengan (Part 2)

Ninjutsu like Rasengan is undoubtedly of great value to Senju Tobirama at this stage. Even after he has developed Flying Thunder God, the value of Rasengan will be further enhanced.

After all, the Rasengan itself is a ninjutsu developed to match the speed of the Flying Thunder God, so Tobirama Senju, who is famous for his speed, would be interested in the semi-finished product in Yuzhen's hand.

So when will Senju Tobirama think that the Rasengan will be "devalued"? The answer is after he develops "Flying Thunder God Slash".

In order to continue developing the Rasengan, Yuzhen needs the assistance of the clone technique, so where does the clone technique come from?

Senju Tobirama struggled a bit, but finally said he could afford to bleed a little more. After all, he had already given away three ninjutsu, so a little more blood wouldn't be a big deal.

"As for the clone technique, I can teach you, Shadow... Um, how about the water clone?"

Fortunately, he is not to the point where he would not feel sorry for selling his father's land for his own son. He does not need a B-level shadow clone, and a C-level water clone is also very practical.

Yu Zhen didn't push his luck further. As long as he could get some benefits, he would be satisfied. So he released the chakra in his hands and started practicing the clone technique.

The clone technique is very practical, or it can be said that it belongs to the most practical type of ninjutsu, because when facing the enemy in battle, 0.5+0.5>1 is often the case.

I have to say, it feels amazing to split your mind in two.

On paper, Yu Zhen's current strength could reach that of a Special Jonin, so this C-rank ninjutsu was easy for him to learn. By the second day, he was already proficient in using the Water Clone Technique.

Senju Tobirama continued to recuperate and had no intention of leaving immediately.

After mastering the water clone, Yu Zhen immediately began the Rasengan "synthesis" experiment.

Yu Zhen is a cautious and safety-conscious person, so he and Senju Tobirama came to a place far away from the camp to avoid any danger during practice.

"here we go."

Yu Zhen glanced at Senju Tobirama beside him, and what he said was both a sign of preparation for practice and a disclaimer... You are so close, don't blame me if anything goes wrong.

As he spoke, he used the Water Clone Technique to distribute part of the chakra to the clone. Then he released the chakra with his left hand and suspended his right hand in the air over his left palm to compress it.

After the chakra ball was "solidified" to a certain extent, the clone's hands began to make the chakra ball rotate clockwise... Referring to Naruto, the copyright owner of this exercise, Yuzhen's movements when making the chakra ball rotate were also extremely ungraceful. The clone's two hands kept scratching left and right like cat paws.

As the clone's hand speed became faster and faster, the chakra ball, or the high-density chakra that made up the ball, began to rotate. At first, the rotation speed was not fast, but with the efforts of the clone's hands, the center point of the chakra ball soon seemed to have a huge gravitational force, guiding the chakra outside to rotate faster and faster.

Then, a short sound was heard, thick but with a hint of lightness, like a gust of wind blowing through a hollow steel pipe.

The chakra was so light and almost weightless, but because of its extremely high spinning speed and the impending impact force, Yu Zhen felt a certain weight in his palm.

“There’s a chance…”

The Rasengan seemed to have both the shape and power, but before a smile could appear on Yuzhen's face, the regular curve of the chakra ball began to twist and vibrate.

Seeing this, Yuzhen subconsciously increased the strength of the binding with his right hand, but this instead caused the chakra ball to vibrate violently, and then...

With a bang like a balloon bursting, the chakra ball in Yu Zhen's hand suddenly exploded. The huge impact force directly turned his clone into a puddle of water, and he himself fell backwards in embarrassment.

The surrounding flowers and plants suffered an unexpected disaster.

What about Senju Tobirama? He'd already quietly retreated to a safe distance the moment the chakra ball showed signs of losing control... Just kidding! As a master ninjutsu developer, how many "experimental accidents" had Senju Tobirama experienced? How could he be affected by such a simple shock?

"I didn't master the final stage well." Yu Zhen said as he got up covered in dust.

Because he had seen hope, he did not get discouraged by the failure, but immediately practiced a second time. The result was the same, another failure.

After five consecutive failures, Yu Zhen made no progress.

At this time, Senju Tobirama, who had been watching silently, said: "Well, how about I try?"

"Of course." Yu Zhen decided to take a break and see if Senju Tobirama had any good ideas.

Senju Tobirama used the clone technique to create two more selves. He had already figured out the trick of this technique.

If the Rasengan is divided into three parts, one part is the large amount of chakra released, and the other part is the high-speed rotation of chakra. These two parts can be said to be quite rough, so the technical difficulty actually lies in the shape control of the last part.

Senju Tobirama's real body cupped his hands and released chakra. One clone controlled the shape of the chakra ball, and the other clone was responsible for the rotation.

After only three attempts, he was able to achieve the same level as Yu Zhen just now.

Although the idea was completely copied from Yuzhen, Senju Tobirama's ability to develop ninjutsu is still amazing.

There was another sound of a balloon popping, and Senju Tobirama himself immediately left in an instant, while his clone was destroyed.

Yu Zhen looked at Tobirama with some resentment, because those clones that were destroyed were shadow clones...it was better to be B-level.

Senju Tobirama was certainly not afraid of failure. In fact, his eyes seemed to be getting brighter and brighter.

The sound of balloons popping began to ring out one after another.

Senju Tobirama, who was immersed in the development of ninjutsu, was much more focused than Yuzhen. They made no progress on the first day, they exchanged their experiences on the second day, and on the third day, Senju Tobirama began to refuse to eat, drink, and talk to anyone.

On the morning of the fourth day, Yu Zhen, who was taking a nap under a big tree, heard that unique sound again, but he just turned over and ignored it.

Forming a high-speed rotating chakra ball is no longer difficult; the difficulty lies in the final maintenance stage, so Yuzhen is accustomed to this sound.

however……

No, Yuzhen didn't hear the explosion.

He suddenly opened his eyes, stood up and looked in the direction of Senju Tobirama.

Tobirama Senju had not slept all night and looked a little sloppy, but his face was full of energy because he and his two clones had finally maintained the shape of the chakra ball. At this stage, it could be called a Rasengan.

"You... your... talent is too high, isn't it?" Yu Zhen was extremely surprised.

He did not use himself as a reference, but used Naruto, who was the fastest and lazy in his steps. It took Naruto a month to learn the Rasengan, and as for Senju Tobirama, it was only the fourth day at most.

"Talent?" Senju Tobirama shook his head, "It's not talent. Instead, I used the dumbest method."

stupid way?

Yu Zhen's eyes were filled with confusion. Was he sure he wasn't being sarcastic or sarcastic?

Chapter 22 Mathematics

Of course, Senju Tobirama was not being sarcastic, he was just telling the truth.

Even though he used one more clone than Yu Zhen when he was experimenting with the Rasengan, this technique is still in the development stage, and the importance of presenting stable results is far more important than its actual combat attributes.

Actual combat is the next thing to consider.

The clone of Senju Tobirama who was responsible for applying the "rotation" released his hands and stepped aside. The original body and the other clone carefully held the Rasengan and placed it close to the trunk of a big tree.

Needless to say, the power of the Rasengan was such that it embedded itself into the tree trunk effortlessly.

Senju Tobirama was very satisfied with this power. At this stage, the Rasengan could finally be truly called a Rasengan.

After dispersing the chakra in their hands, the three Senju Tobirama gathered together again. A moment later, another Rasengan appeared in their hands...

This shows that his recent success was not just luck.

But I really got the hang of it.

Senju Tobirama dispersed the Rasengan again. Seeing that Yuzhen seemed to want to ask, he said first: "I will explain it when I wake up. Now I must rest for a while."

After saying that, he came to where Yu Zhen had just been lying and leaned his head down. In just a blink of an eye, a light snoring sound followed.

Senju Tobirama was indeed very tired.

Although he was extremely talented in developing ninjutsu and could achieve results in such a short time, the effort and sweat he put in could not be ignored.

only……

Yu Zhen actually thought that this kid was quite good at keeping people in suspense.

…………

Senju Tobirama slept for four or five hours. After he had eaten something and replenished enough water, he explained to Yu Zhen:

"Generally speaking, to control the shape of the Rasengan, you need to find a certain 'balance'.

Most ninjas have to rely on their own senses and the experience gained through repeated attempts to maintain this balance.

And if you want to find this right 'feeling', it will take an average person three to five years."

This is quite accurate. If Yu Zhen remembers correctly, it took the Fourth Hokage three years to develop the Rasengan.

"I'm different. I used a stupid method to turn abstract feelings into concrete numbers."

"Tell me in detail?" Yu Zhen naturally wanted to know how Senju Tobirama did it.

"The chakra used to use the Rasengan can be divided into two parts: one part is the chakra that rotates, and the other part is the chakra used to maintain the shape. So how much chakra should be used for rotation, and how much chakra should be used to maintain the shape?"

"Of course, there's a specific answer to this question. If we consider the amount of chakra rotating internally to be 100, then first, to compress the chakra into a spherical shape, the amount of external chakra required must be greater than 100. This is easy to understand."

"When the chakra begins to rotate at a low speed, the amount of external chakra required to maintain the shape is 57."

"When the chakra starts to spin at medium speed, the external chakra amount is 35~~23."

"When the chakra rotates at its highest speed, the external chakra amount drops to 15."

"I figured this out bit by bit through trial and error. It has nothing to do with so-called talent. I really just used the dumbest method."

Yu Zhen: "..."

He could understand that what Senju Tobirama was talking about was not numbers, but proportions, however... this method was indeed very, well, simple, but Yuzhen had never thought of it this way. Who would have thought that data streams would be used in the process of developing ninjutsu.

Not only did he not expect it, but the Fourth Hokage who invented this ninjutsu certainly did not expect it either.

After thinking about it, Yuzhen couldn't help but say: "I didn't expect it to be such an effective verification method. However, accurately controlling the output of chakra is not an easy task for ordinary ninjas."

It is easier said than done. Even if we tell Yu Zhen when to give the amount of 57, can he give it accurately?

Senju Tobirama nodded and said, "This requires constant practice. In fact, even if it's a little blurry, you can still make a Rasengan. However, developing ninjutsu always requires constant improvement."

"57, 15, these numbers aren't accurate either. Next, I plan to refine the ratio of the Rasengan's chakra inside and outside by an order of magnitude."

"..."

What else could Yu Zhen say? He could only say, "You are worthy of me."

Senju Tobirama continued to use the "stupid method" and spent a week, and finally made the data more accurate by another order of magnitude, that is, accurate to one or two decimal places. However, such precise data was no longer what Yu Zhen could pursue.

Yuzhen only wants to be able to use the Rasengan smoothly in actual combat, and does not insist on the maximum or best power of this technique.

According to Senju Tobirama, no matter how sophisticated the Rasengan is, the damage it can achieve will only increase from 100 to less than 110.

Yu Zhen is quite self-aware. When it comes to chakra control, there are things that he cannot do.

Of course, now Tobirama Senju has only found the best ratio. Even for him, it is impossible to apply the Rasengan in actual combat for the time being.

Let’s not talk about Yuzhen for now. Of course, Senju Tobirama’s requirement for using the Rasengan is “instantaneous release with one hand”. Only in this way can it cooperate with his instant body movement technique, which he is still far from achieving now.

In any case, after completing the initial development of the Rasengan, it was time for Senju Tobirama to leave.

His injuries are no longer a problem. In fact, because of the Rasengan, he has stayed here for too long.

When Senju Tobirama expressed his intention to leave to Yuzhen, Yuzhen certainly had no reason to dissuade him. He had already fleeced enough of the sheep, and it would be too rude to force him to do so further.
