Return to the Future

"The future? Big brother, are you kidding me? Are you trying to make me laugh?" Lin was confused. What was he talking about? The future? How could that be? Would such a thing even happen?

"Sigh, I knew you wouldn't believe me. I don't know how to tell you. Anyway, I came here for some reason. In my time, the Third Hokage and Fourth Hokage were no longer alive, and the Fifth Hokage was succeeded by Lady Tsunade... In short, that era is very different from now..." Issui didn't know how to tell Rin, hoping she could accept it.

Lin shook her head helplessly and said, "I still don't understand. What you're saying is too unrealistic..."

"Then there's no other way. In short, I have to go back to the future now, and you have to come back to the past with me. According to the established course of history, you were originally dead, but now I have resurrected you. If you continue to stay here, the future world will probably undergo huge changes. I can't take the risk, and I dare not take the risk..." Issui said firmly. No matter what, Lin could not stay here any longer. She had to go back to the future with him.

"No, I still have my own friends and village. Kakashi is waiting for me to fight alongside him, and there are so many friends in the village..." Rin said, shaking her head silently. Although Yishui had done her Issui great favor, she had her own world and her own life.

"Lin, I want to force you. You know how terrible things would be if history were changed. My family, loved ones, and companions might all disappear. Time and space might be disrupted, and I could never go back to the past. And most importantly, Konoha has already confirmed your death in battle. Your original body has already been buried by Konoha, and now you're standing perfectly intact in front of everyone. Even if you really are alright, they'll still arrest you as a spy. You should understand this better than I do..." Issui said, spreading her hands.

"So what... I can observe them secretly. Anyway, I don't want to leave them..." Lin said stubbornly.

"That's just your fantasy, isn't it? Can you really handle that? Just observing their every move in secret, can you control your emotions and not show them? Once they discover you, they'll definitely treat you as an enemy. What will you do then?" Issui countered.

"I... I... In short, I can't go with you..." Lin was stubborn to the end. She couldn't refute Issui's point of view, but she really couldn't leave this place, this place with so many ties.

"You're so stubborn! I don't know what to say to you. Kakashi and the others will still exist in the future, even if they're in adult form. They're still themselves. Staying here now will disrupt the order of time and space, but once you go back to the future, you can do whatever you want..." Issui advised.

"Are they really here?" Lin asked timidly.

"And I'll even tell you, your teammate Obito Uchiha didn't die either. After he learned that you died at Kakashi's hands, he wanted to destroy the world and create a fictional world with you in it..." Issui couldn't help but reveal all the secrets.

"Obito still alive? Destroy the world? Does he have that ability? Kakashi is much stronger than him..." Rin said with a look of surprise.

"Yes, after he was trapped under the rock, he was rescued by Madara Uchiha. Then, after seeing you die at Kakashi's hands, he learned various powerful Ninjutsu from the Uchiha and trained himself. In my time, your teammate Obito Uchiha even summoned the Nine-Tails to attack Konoha and assassinated your teacher, Minato Namikaze. Minato died not long after becoming Hokage... All of this was caused by your companion. His only goal was to create a fictional world covering the entire globe, a fictional world in which you exist..." Issui said loudly, trying to bring Rin back to her senses and get her to return to the future with him.

Lin's mind was in complete turmoil. These things were too shocking for her. Everything Issui said might actually be true. He came from the future, so what he knew was the most accurate. What should she do? Obito had become a cold-blooded and cruel person for her sake, even wanting to destroy the world. He had even murdered Minato-sensei. Should she go back to the future to stop him?

"Don't think about it anymore. If you don't want to come back with me, that's fine. Then you should live in anonymity from now on, don't let anyone discover your existence, and don't reveal any information about me. If you do come back with me, that would be even better. You still have me, Kakashi, and your comrades in Konoha. Together Teuchi those evil forces, create a new ninja world, completely change this cold-blooded and cruel ninja world, and create a ninja world of mutual trust and understanding..." After saying this, Issui stood aside, quietly waiting for Rin's decision. The reason he didn't use the soul imprint to force Rin to go with him was because he regarded Rin as his own sister, and he would support whatever decision she made.

Lin's head was about to explode. She couldn't stay, and she regretted not staying. In short, she really couldn't make sense of it. What should she do? Sigh, fine, she'd go with him. Since he had told her so much about the future, she couldn't stay in this world any longer. Knowing everything meant enduring all the pain. She couldn't change history, she could only wait silently.

"Alright, I've made up my mind. I'll go with you back to the future. Although I'm a little reluctant, since you saved my life, I'll repay you this once. I won't stay here and ruin history. I'll go back to the future with you to save the world. Besides, I'm really looking forward to seeing Kakashi and the others grow up." Rin steeled herself and made her decision.

Issui hearing Lin's decision, Yishui breathed a sigh of relief and said happily, "That's great! You'll definitely think how wise your decision was later. Let's go, to Rōran in Sunagakure, back to the future..."

Lin looked at Issui Earth Flow happily ahead, shook her head with a wry smile. She really didn't know if her decision was right or wrong, but since she had already made the decision, she might as well do it. Besides, it was her own decision, and if he insisted on taking her away, she really couldn't resist. He had already followed her wishes, so he was a pretty good person. She believed that trusting him once wouldn't hurt.

Issui brought Lin back to Rōran. At this time, Rōran had not yet collapsed, and it was estimated that Naruto others' mission to capture the Mukade had not yet begun. Issui found all the locations of the Dragon Vein according to his memory. At this time, the Dragon Vein had not been sealed. He only needed to Minato's Flying Thunder God Kunai seal the Dragon Vein and then he could go back.

"Lin, let me take you into my spatial world first. You are not from the future. After sealing the dragon Dragon Vein, you will not return to the past, but with my spatial world, you can return to the future with me. Moreover, you were already gone in this world, so returning to the future with me will not have any impact on you. Your body is something I created, so it is like an 'object' belonging to me." The past cannot hold you back.

"Okay, I'll listen to you..." Lin nodded. Although she didn't understand how traveling to the past and future worked, she knew it wasn't a simple matter and there were many things to consider. Issui was from the future and could go back, but she would need to rely on some things to go back herself.

"Don't resist, I'll take you into my spatial world, the Eye of Heaven: Dust, the Sumeru World!" Issui grabbed Lin's hand and gradually disappeared from this world, entering his Sumeru World.

As soon as Lin entered this world, she was amazed. There were flowers, grass, trees, wooden houses, animals, and light. It was a miniature world. Although the glowing thing in the sky was an eye, different from the sun in her original world, it did not diminish the wonder of this world.

"You stay here for now. This is the world as I see it. There's no danger. I'll bring you out when I return to the future," Issui said.

"Okay, go ahead. I want to see your space; it's simply amazing..." Lin was immediately captivated by this world. An independent world, what incredible Secret Technique! He's truly amazing; he can create his own space. He's incredible...

After emerging from the Sumeru Space, Issui nervously inserted the Flying Thunder God Sealing Jutsu into the Dragon Vein. Suddenly, the Dragon Vein erupted with a blinding light, and then his will sank, and he knew nothing more, falling into a coma...

"My head hurts so much, where am I... Oh right, I'm back from the past..." Issui gradually woke up from his slumber. Before him was the sealed Dragon Vein, and the surrounding environment was exactly the same as before he traveled to the past. He was finally back. It seemed that he had not caused much of an impact on the future world, otherwise he really wouldn't have been able to come back.

Even now, Issui is still shaken, fearing that time and space might be disrupted and he wouldn't be able to return to the future. Now, he can finally relax. He's back, he's back. Nothing has changed, the only change is that he saved Lin.

Issui opened his Eye of Heaven, opened the Sumeru Space, and released Lin from inside. At this moment, he immediately discovered that Lin had grown up? What was going on? She looked to be almost the same age as him. You know, in the past, Lin was probably twelve or thirteen years old, but now she looked at least fifteen or sixteen. How could this be?

As soon as Lin came out, she patted her chest and said, "How terrifying! I had just entered your space when, after a short while, I suddenly felt a force acting on me, and I suddenly grew bigger! It gave me quite a fright..."

"Sigh, it seems the influence of time is truly omnipresent. Although my spatial power can protect you, time is the most wondrous and unpredictable thing. Normally, you should be around the same age as Kakashi and the others now, in your twenties or thirties. If you went back to the future, you would definitely be the same age as them. But with the protection of my spatial power, you only aged two or three years. It can be said that the power of time still had an effect. After all, you are from the past, and you would definitely be older when you return to the present." Issui sighed. This spacetime is really not easy to manipulate; it can even affect one's own world. It's terrifying...
