Reborn into Naruto World with Tenseigan

Upon seeing that Raijin not only refused to cooperate but even attacked a ninja of their village, the remaining two Anbu nodded at each other. Their mission was to originally test out the masked Genin squad of Amegakure, so the possibility of battle had been taken into account by them.

After all, only by actual combat can they complete the mission of ‘testing waters.’

Slowly reaching for the sword strapped on their back, the two Anbu lowered their bodies and prepared for battle.

“So, that’s how it is… it seems Konoha ninjas don’t care much about the life and death of their squad mates, huh?” mumbled Raijin with a smirk, then instructed Samsara and Tengu, “The two of you… standby, I will deal with them…”

As both Samsara and Tengu nodded, “Hmm…” suddenly, Raijin’s figure disappeared in a flash of lightning, whoozzzz!

“Wha…!?” The two Anbu were once again takenaback by Raijin’s speed and vigilantly looked around to find his trace.

Suddenly, a faint voice came from behind the two, “Where do you think the two of you are looking?”

The expression of both Anbu changed immediately, and they tried to distance themselves from Raijin only to realize that their body was completely paralyzed, ‘Can’t move at all!’

After paralyzing the two Anbu, Raijin whispered into their ears with a mocking chuckle, “What’s the hurry? Weren’t the two of you going to catch the fugitive and want us to remove our masks and follow you? What happened all of a sudden? Don’t tell me you people changed your mind. I would be very disappointed if that were the case…!”

‘You!’ The two Anbu wanted to speak, however, their mouths were paralyzed because of the lightning coursing through their bodies, so let alone speaking, they couldn’t even twitch their lips.

…

On the side of Kakashi and the others

Asuma looked at the scene in shock, “This… is he still a Genin? To be able to subdue two Anbu while both of them were on guard… His strength is definitely on the level of a Jōnin… No! Perhaps even stronger than that!”

Let alone Genin, even Jōnin ranked ninjas generally do not possess the kind of speed Raijin had displayed. Kurenai and Shizune were certain that they could not move as fast as Raijin did… even Asuma wasn’t completely certain… Only the likes of Kakashi and Guy could move that fast… but even they would need to get serious to move at such an incredible speed!

Moreover, there’s something more about Raijin that shocked the Jōnin instructors, as Guy asked with a frown, “Kakashi… isn’t that similar technique as…?”

Even before Might Guy could complete his question, Kakashi nodded solemnly, “Yes, he is indeed using the Lightning Chakra Stimulation to augment his speed… As I thought, he seems to be incredibly proficient in using the Lightning Nature Transformation!”

Although Raijin did not use more than a few moves from start to finish, Kakashi–who is highly sensitive to the Lightning Nature Transformation–figured out that he specializes in Lightning Nature Transformation based on his observation of the Jutsu Raijin used. Moreover, judging from the speed that Raijin displayed while using the Lightning Chakra Stimulation, it was clear that his mastery of this technique was incredibly thorough.

‘There is simply no way a Shinobi of this caliber can come from Amegakure! He has to have some kind of connection with the Akatsuki Organization!’ Kakashi was more certain of his doubt.

It’s not that he underestimates Amegakure, but for Shinobi to develop their skills, they need training and knowledge, and that knowledge comes from other capable shinobi. No matter how much of a Genius a person is, there is no other way around the need for a mentor/teacher figure. Even the likes of Nagato and Konan received their skills initially from Jiraiya and then developed them further!

As far as Kakashi knows, after Akatsuki withdrew from Amegakure, that village no longer had a shinobi of that caliber. But if it’s the member of Akatsuki that provided Raijin with knowledge and skills, then that would make sense!

…

On the Field

Unlike Kakashi who was trying to figure out the background and purpose of the Amegakure squad, Uchiha Sasuke on the field was completely stunned, he did not even realize it as he subconsciously activated his Sharingan to keep track of Raijin’s movement, and thought to himself, ‘Lightning Chakra Stimulation Method that Kakashi-sense taught me? No, but it’s different… it’s weird…’

Through his three-tomoe Sharingan, Sasuke saw more details compared to others and noticed that the Lightning Chakra Stimulation Method used by the masked ninja from Amegakure seems to be quite different from the one he and Kakashi use.

The most obvious difference between the two Lightning Chakra Stimulation Methods is that Amegakure Shinobi’s Lightning Chakra Stimulation Method seems to cover his entire body, while the Lightning Chakra Stimulation Method taught to him by Kakashi does not cover the entire body. While stimulating the entire body can indeed result in faster bursts of speed, it is also a very dangerous thing to do as the human body cannot withstand such intense Lighting Coursing through it for a very long duration.

Moreover, the degree of Lightning Stimulation the different organs in the body can withstand is also different, so if a similar intensity of Lightning Chakra courses through the entire body, sensitive tissues that cannot withstand high-intensity Lightning would start burning rapidly and might even cause irreparable damage to the body, as a result, not only the complete body Lightning Chakra Stimulation Method would fail to increase the movement speed and reaction speed, but will also cause irreparable damage to the body.

Therefore, Sasuke, who understands this shortcoming of the Lightning Chakra Stimulation believes that the Lightning Chakra Stimulation method taught to him by Kakashi is very advanced Jutsu, and never thought of improving it. However, upon seeing the Amegakure ninja using a more advanced version of the Lightning Chakra Stimulation, Sasuke suddenly realized that he hadn’t really mastered the Jutsu, if he too can emulate the Amegakure ninja’s Lightning Chakra Stimulation Method, his strength would increase!

But there’s still one problem, ‘how did he do it?’

The more Sasuke tried to figure out how Raijin was using the complete body Lightning Chakra Stimulation Method, the more doubtful he became because he wasn’t able to figure out the answer.

It wasn’t just Sasuke who was doubtful, even Darui had a doubtful expression on his lazy face. Unlike Sasuke, he knows the exact implication of the Amegakure Ninja using such a technique. He–who has been training for the past year to master the Lightning Chakra Mode–knows that what the Amegakure ninja is using is actually the second step of mastering the Lightning Chakra Mode!

Lightning Chakra Mode is a unique ninjutsu of Kumogakure, there hasn’t been a shinobi from another village capable of mastering this nin-taijutsu, but now that the Amegakure shinobi has displayed the potential of mastering the Lightning Chakra Mode, this puts Kumogakure in an embarrassing position.

Darui looked at the Amegakure ninja with a serious expression as a trace of killing intent appeared on his face. He knows that the ninjas of other shinobi villages can’t be allowed to master the Lightning Chakra Mode.

Different from Sasuke and Darui, Deidara looked at the Amegakure ninja with an amused expression, “Heh, this ninja is good… maybe participating in the Chunin Promotion Exam wasn’t a total waste of time…” Different from others, Deidara liked the Amegakure ninja’s boldness and looked forward to fighting him.

In the same manner, the others were also more or less impressed by the Amegakure ninja.

Even Orochimaru was a little surprised and licked his lips excitedly, “For such a shinobi to participate in the Joint Chunin Promotion from Amegakure… Interesting…”

While the others were either impressed or vigilant of Raijin, at this time, suddenly a blonde-haired boy with three whiskers on both cheeks jumped out of the crowd and shouted, “Hey… I will fight with you and show you that Ninjas of Konoha do not abandon their comrades!”

Undoubtedly, this person is the most unpredictable knuckleheaded ninja, Uzumaki Naruto.

Hearing Naruto’s words, Raijin turned around and looked at the boy as the corner of his lips arched.

Sasuke sighed, “Sigh… This dimwit… he just had to do it…” Then with his hands in the pockets of his trousers, he came out and stood a step ahead of Naruto as he spoke, “Naruto… you are not a match against him… let me handle this situation…” Then without waiting for Naruto’s response, Sasuke glanced at all the people on the field with his Sharingan before stopping on the three masked Amegakure ninjas and spoke in a cold voice, “I will teach the guy a lesson and let him know not to mess around in Konoha… There is a reason why Konoha is the strongest shinobi village!”

As soon as Sasuke finished speaking, all the eyes on the field shifted to him.

“To make such a bold declaration… Humph, the Uchihas are really arrogant people…” someone spoke in the crowd. While Sasuke’s words about Konoha being the strongest shinobi village might indeed be true, no one from the other villages is going to accept this truth.

Deidara in particular frowned, especially after noticing the three tomoe in his eyes as the previous humiliation against the female Homusubi of Amatsukami had resurfaced in his mind. Looking at Sasuke coldly, Deidara snorted, “He is also a Uchiha… Humph, I will settle the old accounts with the Uchihas this time by crushing this guy…”

It did not matter to him whether Sasuke and the female Homusubi were two different people, it’s all Uchihas in his eyes.

Raijin hadn’t expected Sasuke to jump out along with Naruto, but he reacted quickly and grinned slyly, “Is that the case, huh? Well then… I shall change that false belief of yours today…”

Sasuke snorted coldly, “Humph, your arrogance shall become the cause of your death… In front of these eyes, anything you do is meaningless, I have already seen through your trick…” then disappeared from his position and appeared behind Raijin in the same manner as Raijin. He wanted to use the same method to paralyze Raijin that Raijin had used to paralyze the Konoha Anbu.

“Hooh? Then how about I give you a taste of your own medicine…”
