"Shadow... Shadow! Obito looked at Yamanaka Yuan in disbelief.

"Yuan, you are making progress so fast?" Nohara Rin was also shocked.

"You're such a pervert!" Even Kakashi, who has always been calm, couldn't help but complain about Yamanaka.

After honing on the battlefield for so long, of course they understand what the shadow level means, the shadow level is equivalent to a nuclear weapon in the previous life, and it can deter the existence of a country.

"In fact, your progress is not small, so you don't have to be presumptuous." Bo Feng Shuimon encouraged the three Kakashi, looking like good teachers.

"Speaking of which, Kakashi, what strength are you two now? Obito can barely be regarded as particularly forbearing, you two should be stronger! Yamanaka Yuan asked with interest.

"I should be a ninja, not an elite ninja." Kakashi replied.

"I'm a medical ninja now, and I don't put too much energy into ninjutsu, and my strength is at most an elite ninja." Nohara Lin was a little embarrassed, she was at the bottom of the strength of the three.

Yamanaka remembers that in the original book, Nakahara Rin was a medical ninja, and Kakashi's change of Obito's eye was an operation performed by Nohara Rin.

The inertia of the plot still made Nohara Rin choose to become a medical ninja, but the level of Nohara Rin, a medical ninja, is very different from that in the original book.

"You three, come to me tomorrow, and I'll help you improve your strength."

Originally, Yamanaka Yuan wanted to teach Nohara Rin medical ninjutsu alone, but then he thought about it, teaching one person is teaching, and teaching three people is also teaching, and by the way, Kakashi and Obito were also called.

"I'm busy this time, and I can rest assured that I have a long way to teach you." Bo Feng Shuimen is worried that he has not had much time to teach the three Kakashi recently because of the war, and now that Yamanaka Yuan has taken the initiative to help, Bo Feng Shuimen can also prepare for the war with peace of mind.

The next day, Yamanaka and his party came to the woods behind the Konoha camp.

"That's it, Rin, you wait first, Kakashi and Obito will attack me together, I need to understand your shortcomings."

Obito and Kakashi glanced at each other, Kakashi pulled out the short knife behind his back and poured the [Chidorigi Blade], Obito immediately threw out a smoke bomb, and Kakashi's figure disappeared with the smoke. Obito is harassing Yamanaka Yuan with various fire escape ninjutsu.

Yamanaka didn't expect that the two people, who are usually noisy, would have a tacit understanding with each other. Obito feints Kakashi and waits for an opportunity to kill with one hit.

Obito's fire escape did not affect the mountain at all, and the ice wall in the far mountain blocked Obito from all attacks.

Kakashi was a little anxious when he saw that Obito's attack had no effect. Not hiding his figure, he used the special instantaneous body of the Qimu clan to approach the mountains far away.

The short knife infused with the [Thousand Bird Blade] slashed down at Yamanaka Yuan with a thunderbolt light, and Yamanaka Yuan smiled slightly and did not dodge, and used the ice wall to defend Kakashi's sword.

"[Fire escape. The dragon sings]! "As soon as the wall of ice in the far reaches of the mountain moved, the earth-covered fire escaped and followed.

Yamanaka looked at them with some admiration, and the cooperation of these two people with elite shinobi may suffer a big loss if they don't check it for a while.

It's a pity that it's not enough for him. Yamanaka Yuan used an ice scalpel to split the earthy fire dragon, and then the thunder flashed on his body, and he entered the ice thunder mode.

Ray instantly appeared behind Obito and subdued Obito with Ice Escape, and then concocted it in the same way, and the time that Kakashi didn't react was also frozen.

It all happened between the lights and the fire. Nohara Rin, who has no perception and no writing wheel eyes, was frozen just by seeing the lightning flash Obito, and then Kakashi was also frozen.

"Far, you... Are you instantaneous? Or is it a space-time ninjutsu? Nohara Rin asked in surprise as she looked at the two who were frozen in ice.

"This is the thunder instant body of the Thunder Escape Chakra mode, and it is the same technique as what you saw before, but my mastery of this technique is more perfect." Yamanaka said with a smile.

"How can it be so fast? It feels the same as Mr. Watergate's Flying Thor. ”

"That's just because you don't have pupils, you don't have the ability to perceive and you can't sense my movements."

The two chatted for a while, and Yamanaka remembered Kakashi and Obito who were frozen in ice, and hurriedly thawed them.

"Sneeze ——, Mountain... Yamanaka Yuan, you bastard, one day I'll freeze you in ice too. "Obito has been frozen for so long, and he has a cold, but he still doesn't forgive.

Kakashi wasn't much better, sneezing all the time like Obito.

Yamanaka Yuan was a little embarrassed, chatting with Nohara Lin and forgetting the two of them, so he didn't refute Obito scolding him.

"Ahem, accident, this is an accident. In order to compensate you, I will help you improve your strength in the future. ”

Seeing that the two of them didn't react, Yamanaka Yuan continued to speak.

"Kakashi, your concealment just now was not bad, but it's a pity that your concealment was just a joke when there was a sentient ninja."

"I know this, do you have a solution?" Yamanaka's words managed to get Kakashi's attention.

"Don't worry! Next is Obito, do you want to make the temperature of the fire escape? I can teach you about the nature change of the fire attribute. ”

"I don't believe it, you don't have a fire attribute, how can the nature of the fire attribute change." Obito was obviously also moved by Yamanaka's incorruptible tongue, saying that he didn't believe it, and the expectant light in his eyes couldn't be faked.

Intellectually speaking, Yamanaka is far from having a fire attribute, and it is impossible for the nature of the fire attribute to change, but Obito thought about it and thought that Yamanaka had never deceived him, and he still believed Yamanaka's words.

"That's right! Kakashi, I have a secret technique here to hide the chakra, and if you learn it, you can cover the chakra, and the perception ninja won't be able to find your traces. With that, he handed Kakashi a scroll.

This jutsu Yamanaka had planned to teach Kakashi a long time ago, and if Kakashi was going to focus on swordsmanship like Hachiki Sakumo in the future, this technique would help him a lot.

"As for Obito! I won't change the nature of the fire attributes, but I still know the theory, do you want to know? ”

"Yes! Stinky fart, go far in the mountains, hurry up! Don't sell it. Obito Kakashi was a little red-eyed when he got such a precious secret technique, but he knew that he was not suitable for that technique, and it was more attractive to him than the change in the nature of the fire attribute.

Yamanaka Yuan smiled slightly, and unhurriedly told Obito about the changes in the nature of the fire attribute.

As for Nohara Rin, Yamanaka Yuan started from scratch the modern medical knowledge that he had taught those medical ninjas before, planning to familiarize Nohara Rin with current medicine as soon as possible, and after the 10 people of the medical team arrived, let Nohara Rin follow them to practice.

In this way, a week has passed, and Kakashi's hidden chakra secret technique has been successfully cultivated, and the nature of Obito's fire attribute has changed.

With the help of Yamanaka Faru, Nohara Rin learned about the system of modern medicine and learned some simple first aid.

At the same time, the medical team from Yamanaka arrived yesterday.

After that, Yamanaka Yuan took Nohara Rin to the medical ninja team, and asked the team to take Nohara Rin to engage in various rescue work while learning and practicing.
