Saving Rin (Part One)

The next day, at Issui, Ichisui left Kikyo Castle. He knew very well that Konoha should have won the Battle of Kikyo Castle because Konoha had a group of powerful ninjas such as Orochimaru, Jiraiya, and Minato, which Sunagakure could not compare to. And when Sunagakure realized that their Third Kazekage might really disappear, they would have the idea of retreating.

Although many years have passed since Second Shinobi World War, and the various ninja villages have recovered and it's time to redistribute power, Konoha is now extremely powerful. Two of the Sannin, Minato Namikaze Yellow Flash, and Hiruzen Sarutobi, the Shinobi World Professor... the existence of these people makes Konoha the most powerful village today.

After the Battle of Kikyo Castle, Konoha faced an even worse situation. Orochimaru defected, the Land of Earth declared war on Konoha, Land of Lightning and the Land of Water also declared war on Konoha. It can be said that Konoha was simultaneously fighting against attacks from four powerful ninja villages during the Third Shinobi World War, but Konoha's resilient nature allowed it to survive once again.

However, after the Nine-Tails attack and the departure of the Fourth Minato Namikaze, Minato Namikaze, Konoha's strength gradually declined. The village only had the Third Hokage as a powerful ninja. Tsunade left the village to travel, Orochimaru defected, Jiraiya left to pursue Orochimaru. It could be said that Konoha at this point had no remaining strength for fighting. This is also why, when Hinata was kidnapped by the leader of the Cloud Ninja when she was young, Hiashi killed the kidnapper, but to appease the Cloud Ninja's discontent, he had Hizashi die in Hiashi, and the body was even sent to the Cloud Ninja. This indirectly shows that Konoha was no longer capable of fighting and had to swallow its anger for the sake of peace.

However, after the Third Shinobi World War, not only Konoha suffered heavy losses, but other ninja villages also suffered considerable losses.

The Iwa ninja Kannabi Bridge, was utterly defeated by Minato Namikaze, and retreated to his lair, never to recover.

The Third Raikage of the Cloud Ninja was assassinated by the Iwa Ninja. It's possible that the Iwa Ninja hired the Akatsuki to help kill the Third Raikage. Later, the Fourth Raikage and Killer B's A–B Combo suffered a major defeat at the hands of Minato...

The Land of Water fared even worse. It suffered a defeat in its war with the Land of Fire, and the Fourth Mizukage, Yagura, was controlled by Obito. Obito implemented numerous policies detrimental to the village's development, leading to the extermination of many of the major Kekkei Genkai families in the Land of Water Yuki. Only Haku remained of the Mizuki clan, only Kimimaro of the Taketori (Shikotsumyaku) clan, and only Suigetsu of the Hozuki. The only surviving Kekkei Genkai family was the Terumi Clan, the future Fifth Mizukage Mei Terumi. Fortunately Mei Terumi's power overthrew the Fourth Mizukage's rule, allowing the new Kirigakure to slowly recover.

War is the source of turmoil. As can be seen from the above analysis, the national strength of various countries declines significantly after a war, and it takes more than ten years for them to recover. Akatsuki probably saw this cause and effect relationship, so they continuously hired various ninja villages at low prices, deepening the hatred between them, eventually triggering war, weakening the strength of various countries, and then collecting the Tailed Beast to control the world.

Although each ninja village was well aware of the situation, everyone was acting in their own self-interest, blinded by their own involvement. Issui, on the other hand, was a clear-headed bystander. One of the reasons Issui didn't want to get involved was because he disliked this meaningless killing. Everyone was killing each other, and in the end, no one knew who they had killed or who had killed them.

Besides, nothing stays hidden forever. Although Issui has only been in this world for a short time, he has already caused quite a stir. His defeat of the Sannin and Chiyo has brought him more and more attention, which is not a good thing. After all, every move he makes could change the future world order, which is no joke. One wrong move and spacetime might be disrupted.

After his battle with Chiyo that day, Issui disappeared without a trace. No one could find him; it was as if he had vanished into thin air, or as if he had never existed at all.

Over time, everyone gradually forgot about Issui's existence and became engrossed in the intense battle.

Jiraiya and Minato searched carefully, but couldn't find any trace of Issui in many places. Then they ran out of energy to search further, as the fierce battle was gradually intensifying. They were the main force on the battlefield and couldn't afford to falter at this crucial moment.

In the end, they had no choice but to give up the search for Issui; perhaps, like Tsunade, Izumo the world...

During the Third Shinobi World War, Issui disguised himself as an ordinary person, spending his days in bustling towns, living a simple and peaceful life, far away from the hustle and bustle of the ninja world. He gradually grew to like that kind of life, living carefree.

But on this day, his heart was no longer at peace.

"Have you heard? The Land of Fire and the Land of Water are at war again..."

"Really? Sigh, why are other countries always targeting our Land of Fire? After the victory at Kikyo Castle a while ago, the Land of Earth declared war on us. The battle with the Land of Earth isn't over yet, and now the Land of Water has declared war too. Do you think our Land of Fire will be in any danger? I'm really worried. Our little town isn't far from Kirigakure. What if the Kirigakure ninjas attack?"

"It's alright. Haven't you heard that a superhero has recently appeared in Konoha — the Yellow Flash? I heard he killed Jonin fifty Iwagakure in an instant... With the Yellow Flash around, the Land of Water will probably win this time too..."

"Oh, the hero you're talking about? I know him, but I heard he's on some mission recently, sending his disciple to fight first, and then he'll officially appear to fight the Kirigakure Village after the mission is over..."

"Oh, I see. Too bad it's not Yellow Flash..."

"Tch, you're really ignorant. The Yellow Flash's disciple is also very powerful. I heard he's the youngest Jonin Konoha, and his strength is considerable..."

"Oh, that's for sure. If Master is amazing, then of course your disciple is amazing too..."

Inside the tavern, everyone was talking at once, and most of the information was related to Third Shinobi World War. Minato's reputation was spreading rapidly, and his fame was growing.

If I hadn't Issui to the hotel, I really wouldn't have known about the recent situation in the ninja world. I didn't expect Kakashi and Rin to already be on the battlefield. He can't relax anymore. Saving Rin and then going back to the past is the right thing to do.

After having a few drinks and a snack, Issui quickly paid the bill and left.

Although Issui wanted to save Rin, how to do it well was what he had to consider. After all, he couldn't disrupt the course of history. Rin had to die, otherwise how could Obito's personality have changed so drastically and become the renowned Obito Uchiha in the future?

Since they couldn't prevent Rin's death, the only way to save her was to revive her. They would use the Flesh and Flesh Activation Technique to recreate Rin's body and imprint her soul on it. Although it was a bit troublesome, it was the only way at the moment. If they had the Rinnegan, they might be able to use the Samsara Rinne Rebirth to bring Rin back to life, but Issui doesn't have the Rinnegan, only the Eye of Heaven.

Perhaps while creating a new body for Lin, he could alter her bloodline, perhaps by incorporating his own bloodline power. Since he was going to modify her, he might as well do it perfectly. He already considered Lin his younger sister because when he first transmigrated, Lin called him "Brother Takuya." Although Takuya was just Issui fictional character, he could genuinely feel Lin's kindness. For this reason alone, he couldn't let this lovely girl leave this world.

After making his decision, Issui prepared everything and headed towards the battlefield between Konoha and Kirigakure.

When Issui arrived at the battlefield between Konoha and Kirigakure, Rin and Kakashi had not yet set foot on the battlefield. They were resting at the camp and organizing their belongings. Issui quietly hid in the shadows and observed their every move.

"Kakashi, do you think we can succeed in this mission?" Rin asked worriedly, her voice a little low. The long war had put immense psychological pressure on her. In the Battle of Kannabi Bridge, Obito had sacrificed himself. If it weren't for her, he wouldn't have died. She felt so useless.

Kakashi was silent for a moment, then said, "We'll definitely succeed. Don't worry, Rin, I'll protect you..."

"Hmm..." Lin gave a forced smile, then lowered her head and began tidying her things.

"Kakashi, I... I want to join Konoha's Medical Team after this mission..." Rin said suddenly as she packed her things.

"Ah... okay..." Kakashi was taken aback for a moment, but quickly understood. He knew that it would be difficult for a girl like Rin to survive on the battlefield. Her only skill was Medical Ninjutsu, and Obito's death had left her with too many scars. It was good that she was in the Medical Team, so she would be safe. He had promised Obito that he would protect Rin and never let her die.

Issui sighed upon seeing this. Life is so cruel. Rin and Kakashi probably didn't know that this mission would turn their two-person team into a one-person team, and the former Team Minato would only have Kakashi as a member.

"Rin, you stay here. I'm going to gather some intelligence on this mission. Knowing your enemy and yourself is the key to victory..." Kakashi finished packing, said to Rin, and then went out.

"Okay..." Lin nodded.

After sensing Kakashi's presence disappear, Issui emerged from the shadows and casually found a place to sit down.

"Who? You... you're Brother Takuya..." Lin was startled when she saw a figure suddenly appear in the room, but she was also pleasantly surprised when she saw the person's face. She hadn't expected Brother Takuya to be here. She had been saddened when she heard the news of his disappearance.

"Yes, it's me, Lin. You've become even more beautiful in just a few days..." she complimented.

"Ah..." Lin blushed and hummed in response, feeling a little shy. It was the first time a boy had so boldly called her beautiful, which made her quite embarrassed.

"Huh... how have you been lately?" Issui lightly flicked Lin's head with her finger.

"Hmph, how dare you treat someone like that..." Lin touched her head angrily, but her expression immediately darkened. Thinking about her recent experiences, she was in a bad mood. Obito's death and a series of battles left her breathless. She joined the Medical Team to escape the war.
