"Just a little bit more." Ryoha constantly muttered. Strangely, he was not using the same Kunai as Minato, but instead, he opened his Mangekyo Sharingan and stared at it.
If someone used Byakugan here, They would find that there was a layer of chakra on the Kunai that was difficult to see with the naked eye. This was the formula for the Flying Thunder God Jutsu.
Ryoha had already found a way to imprint the formula on the medium, which was to use his Mangekyo Sharingan. After comprehending his own Kamui, he had some special use of this jutsu, which was to use the Kamui to imprint the formula on his Kunai.
Since Kamui could move anything to its own dimension according to the user's will by distorting them, then using this principle, he should be able to use the power of Mangekyo Sharingan to carve the jutsu's formula in the place he saw. Of course, this was only a theory.
After countless improvements and experiments, in order to complete his own Flying Thunder God Jutsu, Ryoha even disregarded the damage to his eyes and used Kamui multiple times to clearly make himself feel the change in the process, and finally,, found a way.
As long as he succeeded, then this would be an optimization of the legendary jutsu, forming his own unique version of it. As long as he reached the second stage of the jutsu, he would not need to spend a certain amount of time engraving the formula on the medium instantly.
Then Ryoha only needed to open the kaleidoscope to place the formula. In battle, it was more convenient than the one used by Minato, and its usage would suit Ryoha's fighting style more. Of course, the premise was that Ryoha could succeed in the first stage of the jutsu.
"Just a little bit more. My eyes are a bit numb." Ryoha used the power of Mangekyo to draw formulas and then imprinted them on kunai. Although it didn't consume his eye power, highly concentrated control of the Nine-tails chakra was very taxing on the mind, and drawing the complex formula also needed great concentration.
Therefore, Ryoha was very tired of doing this. His eyes constantly released chakra that could not be seen by the naked eye. How could he not be tired? This was not a 3-tomoe, but a Mangekyo. The amount of chakra required to maintain the use of the Mangekyo was a lot.
"Okay." After more than half an hour of hard work, Ryoha finally finished drawing the formula and imprinted it on the Kunai. At this time, Ryoha finally understood why Minato, who was regularly the Flying Thunder God Jutsu, would bring a lot of special Kunai.
Because to complete the first stage of the Flying Thunder God, he had to spend a lot of time drawing the formula on different mediums in advance and then use it in battle, and it was impossible to temporarily use it in battle.
Only by reaching the second stage could he instantly engrave the formula on various mediums so that in battle, Minato could use the jutsu because at the second stage, he could instantly draw the formula where his hand touched and seal it in that place.
"Just one move will make me exhausted, but it's all good. As I continue to train, I will become more and more skillful, and I will consume less and less effort to draw the formula, and my speed will be faster. I need to work hard." Ryoha walked back into the room. He was very tired and wanted to rest.
As for the kunai, he put it in his pocket. Although he had not tested the taste of using the Flying Thunder God Jutsu, he was very tired now. He should take a rest and try it later.
"It seems that you have succeeded, right?" Bulma looked at Ryoha's tired appearance. These days, Ryoha had been immersed in his study besides the usual exercise. Now seeing him like this, he should have succeeded. How could Bulma not be happy?
"I was able to engrave the formula, but I haven't used it yet. I don't know if it will succeed." Ryoha casually took out the Kunai he used earlier and put it in Bulma's hand. Then, he lay down on the sofa and fell asleep.
"This kid really succeeded? I really can't underestimate this guy." Byakko jumped over and looked at Ryoha's Kunai up and down as if there was nothing special about it.
"There is a formula that can't be seen with the naked eye on it. Of course, there is nothing special about it." Tsunade was also a little curious. After all, she also knew about the Flying Thunder God Jutsu. It was very powerful in battle. Therefore, she had also walked over to see this Kunai.
"However, he should have just developed it. Therefore, the first time he imprinted the wood style, he exhausted his mental strength. That was why he was so tired. As he continuously used it, it would not be like this soon."
Tsunade's words were true. As Ryoha practiced his formula drawing more, the number of times he could engrave them increased. The consumption of his mental strength was also decreasing.
At this rate, Ryoha would reach the second stage of Flying Thunder God in no time. At that time, he would be able to use the real Flying Thunder God jutsu.
Today, Ryoha got up early and came to the snowy plains to exercise his body. Recently, he was either training in the gravity chamber or practicing his formula drawing. He was too tired. Today, he had to relax his mind.
"Someone is coming. There are four powerful chakra sources." Haku suddenly walked out of the house. It could be said that nothing in this snow could be hidden from Haku's perception.
"They should be targeting us. It's strange. They are the only ones who can find us here. Byakko, you stay in the house and protect Bulma. Tsunade may have to trouble you this time."
Ryoha knew that it was too difficult to deal with four people with just him and Haku alone.
"Well, anyway, I have some time to move bones." Tsunade clenched her fist and said.
Just when Ryoha and the others were ready to fight, four figures had already entered Ryoha's line of sight among the snow. From their appearance, Ryoha could already tell who they were.
"Sorry to trouble you, it really is the Akatsuki. It seems that they have noticed me. Their goal is either pulling me into the organization or killing me. But there is no other way. Since you have come, let's fight. This is a good opportunity to test the results of my training."
Ryoha opened his Sharingan, and his vision became stronger. All of a sudden, the appearance of the four intruders fell into the range of Ryoha's sight.
