Rinnegan

"Let's train him normally for now; he's too young," Namikaze Minato said first.

The Third Hokage chimed in in agreement. "Alright, there's no need to rush things regarding the Uchiha. I believe Shisui can easily gain the villagers' approval, which will make communication much smoother."

If Uchiha Shisui were to be transferred to the Anbu reserve team for training now, the village would be behaving in a very unseemly way. It would be tantamount to snatching the Uchiha Clan's top genius from the Security Force, which would only cause controversy.

Therefore, the young Shisui can only be trained as a formal ninja for the time being, while the other talents will be arranged by Minato himself. Whether or not to recruit them into the Anbu will only be determined after contact.

After the heavy snow, Konoha began to enter spring, and the ninjas once again fell into the cycle of missions and training.

In the training ground, Shuichi stood in front of Kakashi and began to demonstrate his various abilities to him.

"This is Lightning Release: Chidori series Ninjutsu, a technique derived from the nature of Lightning Cutter." Shuichi pointed two fingers at the wooden stake in front of him, "Chidori Sharp Spear!"

Sizzle... The slender Lightning Release Chakra pierced right through it. "This move weakens the power of the Lightning Cutter but extends its attack range, making it barely a mid-range offensive technique. And then there's the Chidori Stream, which unleashes a massive amount of lightning from the body. You've seen that move before; it doesn't quite suit your mobile fighting style."

The reason these Lightning Release are not very suitable for Kakashi is because they consume a lot of chakra without achieving the one-hit kill effect of the Lightning Cutter. It is believed that he was able to research these techniques in the original work, but gave up because he found that they were not applicable to him.

"Next comes the good stuff, my unique Explosion Release Ninjutsu." Shuichi dispersed his Lightning Release and then quickly slapped the wooden stake.

After a soft sound, a small pit appeared on it, and a breath blew on it, bringing out countless tiny wood chips.

"This technique should suit you perfectly. It consumes little chakra, is highly lethal to the enemy, and is also very stealthy." Shuichi thought that Explosion Release was indeed in line with Kakashi's style.

"With the help of the Sharingan, not only is close combat easy, but I can also see through the enemy's meridians. This allows me to inflict damage while disrupting the enemy's chakra flow, making the kill a natural next step."

Kakashi could imagine the astonishing power of this technique; it was practically impossible for ordinary ninjas to defend against, and its efficiency in injuring enemies was too high. "I've encountered quite a few Stone Ninja's Explosion Corps, and they don't seem to be able to use Explosion Release like you. Is there some limitation?"

"Yes, simply put, it's very difficult..." Shuichi explained.

First, one must have a high level of proficiency in Nature Transformation, because this is a release without a seal, and the goal is to be fast and covert.

At the same time, one's own chakra strength must far exceed that of the opponent. Since there will inevitably be energy attenuation during the process of injecting the chakra into the enemy's body, if there is no obvious advantage in chakra quality, then at most it can only cause a minor injury. There is also the risk of being countered by the enemy after getting close, so using this move is completely not worthwhile.

"You've also trained in chakra compression before, so you have the potential to use it. This Nintaijutsu is very compatible with the Sharingan and is a very suitable technique for you, but the training time won't be short."

Shuichi had calculated that his chakra reserves were several times that of Kakashi's, and his control over them was far superior. Based on their initial training progress, Kakashi would likely need to practice for more than three years after mastering the Explosion Release before he could perfectly apply it in actual combat.

However, this seemingly simple move actually targets the core of the Explosion Release's power. Once mastered, it makes other types of Clay Bomb completely insignificant, and you can freely adjust the amount of chakra output to control the power you want.

Next, Shuichi demonstrated other techniques, with various Ninjutsu such as Explosion Release Clone, Clay Bomb, and Flying Thunder God appearing before Kakashi's eyes, leaving him in a dilemma.

"The Lord Hokage has transferred me to the Anbu, and I'll be reporting for duty in a few days," Kakashi said with a hint of helplessness. "I simply don't have enough time to learn all the Ninjutsu; I can only choose one..."

Shuichi wasn't surprised that he would join the Anbu, because Minato didn't have many direct subordinates to use, and under such circumstances, he would basically not let go of his personal disciple.

After repeated discussions, Kakashi ultimately chose to study Explosion Release, having to abandon Flying Thunder God and White Fang Swordsmanship for the time being. In the future, he plans to use Lightning, Earth, Explosion Release, and Sharingan as his main methods, pursuing an all-around path in Ninjutsu.

"Alright then, use your Sharingan to observe my chakra flow, and I'll explain everything to you all at once."

This is why Explosion Release is chosen; having a successful practitioner guide you through training is much simpler than researching it on your own, highlighting the importance of Ninjutsu inheritance.

Seeing the Tomoe swirling in Kakashi's eyes, Shuichi extended his left and right hands, "This is Lightning Release Chakra. Activate its most violent aspect as much as possible."

"The key is Earth Release chakra. You need to practice extracting this weightiness, which is somewhat different from simply bearing its weight. The technique is..."

"Once you've completed the first step, things will be much easier." Shuichi began to bring his hands together. "Think of this Earth Release Chakra as a resilient net, enveloping the raging Lightning Release. Then, just keep increasing the proportion of lightning. The stronger your chakra control, the greater the power. You can refer to my..."

Teaching Kakashi the Explosion Release technique was also a way of indirectly telling the Konoha High Command about the techniques he possessed. This kind of teaching was equivalent to contributing his family's secret techniques to the village, which would become one of Konoha's foundational assets in the future. Its value could not be measured by merit or money; those who understand would naturally understand.

The Land of Rain, where a continuous drizzle falls, is like a child who is forever crying.

The heavy rain seemed to wash away the sins and bloodshed. On a small hillside, a large number of ninjas stood side by side in two groups, facing only two enemies with whom they had formed a united front.

"To me, your organization is a huge problem." The masked Hanzo of the Salamander threatened a woman with Kunai, "Yahiko... as the leader of the organization, I need you dead here. If you dare resist, this woman will die."

"Tch!" He threw another Kunai at the two of them and continued, "That red-haired guy, use this to kill Yahiko, and I'll let you and this woman go."

"No! Nagato! Don't worry about me, you two run!" the blue-haired woman Konan, shouted.

Such a cruel choice caused Nagato immense pain, but under Hanzo's repeated threats, Yahiko rushed to his side, grabbed the hand holding the Kunai, and slammed it against him.

"You and Konan, you must live no matter what..." Nagato's eyes widened, trembling, her hands wet with either rain or blood, and she stood motionless.

"Yahiko!!"

Having achieved his goal, Hanzo did not let them go. Eliminating any potential threat was a tradition of Amegakure. "Kill!"

"Whoosh..." A barrage of ninja tools shot down at Nagato from above, and his expression turned extremely ferocious. He raised his hand and a powerful force seemed to surge out, instantly deflecting all the Kunai. Then, he jumped directly onto the platform to save his comrades.

Seeing that ranged attacks were ineffective against him, Hanzo immediately decided to use Konan as bait to launch a surprise attack and kill him.

"Despair!"

The Nagato landed, Hanzo, who had dodged almost simultaneously, completed Hand Seals Hanzo, unleashing "Fire Release: Explosive Flame Formation!"

Countless Explosive Tag on the ground bound Nagato's legs, and soon a violent explosion occurred, "Boom!"

Many Amegakure looked towards the smoke, but found no one there. Hanzo had already seen his escape and noticed the unusual nature of those eyes. "These eyes are..."

After hesitating, Hanzo did not attack immediately, but instead commanded his men to launch an attack. The Konoha Allied Forces beside him also moved with them, and a large number of people rushed towards Nagato.

Just as they were about to be overwhelmed by the enemy, Nagato slammed one hand on the ground, and in an instant, the entire area collapsed and the earth cracked. A gigantic monster appeared and with a wave of its hand, it sent many of Konoha and Rain Village Forces flying.

"Roar..."

A deafening roar echoed through the arena. The ninjas only saw the bodies of the people in front of them connect with the monster, and then a bright dragon flew out of its mouth. All the teammates who were touched fell down without any sensation.

Once the surroundings quieted down, Hanzo and the others on the hillside had disappeared. Sensing the danger, they fled the area immediately, as confronting this unpredictable monster head-on was hardly a wise move.

Two months passed in the blink of an eye, but the turmoil in the Land of Rain did not subside. While the surrounding great powers began to recuperate, this place became a new battlefield.

In the rainforest, several figures were desperately fleeing, while someone was chasing them at lightning speed, moving rapidly before blocking their path.

The newcomer wore Cat Mask and drew a short knife from behind him, seemingly ready to attack at any moment.

"It's Konoha's Anbu! Hanzo actually colluded with the Land of Fire to hunt us down!" one of them shouted in a desperate tone.

The others also looked on with hatred, roaring, "Since we can't escape, let's fight him to the death!"

"Drink up..."

The white-haired Konoha Anbu, despite being outnumbered, remained calm and charged directly into the enemy formation. The clanging sounds of their fighting echoed throughout the field. He remained composed despite the attacks from all sides, seemingly able to easily anticipate his opponents' movements.

"Sizzle!"

Kakashi plunged the dagger into the heart of the last enemy, then quickly examined and processed the corpses, confirming their identities by comparing their physical characteristics. He then vanished from the spot in a flash.

He walked through a vast rainforest to the edge of a cliff, where two people were already waiting. They weren't surprised to see him arrive.

"Captain Shuichi, all the targets on this list have been eliminated," Kakashi reported as he approached.

"Pretty fast, how strong is the opponent?"

"They pose virtually no threat, their fighting style is unorthodox, and their skill levels vary widely."

A member of the Anbu codenamed Zhu chimed in, "It's the same on my end. Logically speaking, even if Amegakure is at its worst, it shouldn't have fallen to this level, right? It feels a bit strange that they have to send people to Konoha to hire people to clean up these missing-nin who pose little threat."

"Brush!"

As they were talking, another Anbu arrived at the rendezvous point. "All done. Looks like I was unlucky; these guys split up and escaped, which took some time."

"Let's go!" Shuichi led his team into action. "We'll collect the final payment from Amegakure and then return to Konoha. If I'm not mistaken, Hanzo is definitely hiding some information from us, but the mission is complete, and he can't back out now."

This mission was arguably the most disappointing one in Shuichi's career. Hanzo, the leader of Amegakure, had recently sent someone to secretly commission Konoha to jointly eliminate the rebellious forces within the country.

Both Hokage took this very seriously; Amegakure's sudden show of weakness towards the Land of Fire was a good thing for Konoha.

Strengthening invasions of neighboring small countries is a way to keep enemies outside the country's borders, but the fact that Demi-God would issue commissions to foreign countries makes them suspect that there might be a trap involved.

After careful consideration, Konoha decided to send three Anbu teams, led by Shuichi, to carry out the mission, since Minato was unable to participate after becoming Hokage.

As expected, these rebel forces posed no threat whatsoever and were easily wiped out.

After all the teams successfully assembled, the Konoha members arrived at the entrance of Amegakure. Shuichi handed several lists to their leader and said, "We have successfully killed all the missing-nin. Now, please pay the remaining commission."

Seeing that everyone on the other side was unharmed, the leader of Amegakure seemed to be holding back some tension. "Are you sure you didn't let any of them escape? Our intelligence indicates that there are quite a few skilled missing-nin among them."

"Are you questioning the credibility of Konoha?" Shuichi stared intently at him, his chakra exploding and dispersing the surrounding rain. The person in charge of the other party collapsed to the ground.

The Amegakure shocked by his strength, then quickly recovered, "No... excuse me, please allow me to report to Lord Hanzo that the commission will definitely be paid to you, please wait a moment."

Amegakure has a very unique appearance. The entire village consists of Tower- shaped buildings, mainly constructed of steel and stone. The outer walls are surrounded by steel pipes of various sizes, and there are probably various pipes and sewers underground. It is easy to guess that this is to cope with the environment of constant heavy rain.

The village wasn't very large. Shuichi close eye on the person's figure and then silently used his Sensory Ninjutsu to easily discover that the chakra intensity in a certain building deep inside was far greater than in other places.

"Was Hanzo beaten half to Rinnegan?" Based on information from the original work, he began to speculate on the causes and consequences of this hiring.

If nothing unexpected Danzo was definitely present, and after returning to Konoha, he concealed the information about the Rinnegan, keeping it a secret from Minato and the Third Hokage.

Shuichi guessed that Danzo might have become greedy for the Rinnegan and wanted to find an opportunity to take it for himself in the future. At the same time, through investigation, he should be able to find out the identities of Nagato and others, thus also gaining leverage over Jiraiya. If the two of them were to compete for the Hokage position in the future, it could be used as a trump card to turn the tide.

Hanzo's request is easy to understand; there must be remnants of Akatsuki Organization among these missing-nin, and it would be very dangerous for him to Rinnegan.

He had considered whether the people of Konoha would encounter Nagato. Even if they didn't, it would only mean paying more money. It would be worth it to indirectly drag Konoha down and make them enemies of the Rinnegan.

"Gentlemen, I apologize for keeping you waiting." The person in charge of Amegakure ran back shortly after, handing the package to Shuichi. "This is the remaining commission. I hope there will be opportunities to cooperate in the future."
