"In order not to change history, it is better to erase all our memories here. I've set up a technique to make each other forget about each other, okay! Although Watergate's last sentence is a question sentence, the tone is unquestionable.

"Changing history? Can history be changed? Unexpectedly, Naruto hadn't said anything yet, but Hitomi Hinata said so.

"Why are you wearing a mask?" Here, Yan suddenly asked Hitomi.

"Decay is just to avoid unnecessary trouble, that's all." Saying lightly, Hitomi Hinata pulled the mask aside, revealing the cold face under the mask.

At this time, looking at the girl's double horns, Qi bangs' bun, with that cold face, and Yan who looked at the white-eyed girl, he felt a little undetermined in his heart.

"Hinata?" Looking at the white eyes of Hitomi, Shuimen was stunned for a moment, and said in surprise.

"The so-called history, I think, history is an inevitable and unchangeable result, have you ever heard of my grandmother's refutation?"

"She's probably just like me, a traverser!" Through the refutation of the grandmother who does not exist in this world, Yan deduces the identity of the girl in front of him.

"There was such a man who went back in time and accidentally killed his grandmother, who was not yet married. Then the problem arises, if you kill your grandmother, who is not married, your own father does not exist. Since his father no longer exists, that person does not exist either. Since that person didn't exist, the killing of the grandmother never happened. Since the killing of his grandmother never happened, his father existed, and he also existed. And if you exist, you can kill your grandmother who is not married. ”

"Infinite loop, if history can change, I and all the predecessors in front of me will fall into endless reincarnation." The voice was cold and clear, and Hitomi Hinata's words made everyone except Yan fall into deep thought.

"If history can't be changed, what is your influence?" With his eyes narrowed slightly, Yan looked at this woman with an outstanding fairy posture and asked.

To use an analogy, a tree has a trunk, branches, and leaves. What is Tree Trunk? The trunk is the history before the hundred feet came to this era. ”

"Then, because of Baizu's actions, the timeline was different. Starting from the trunk of the tree, there is a branch, which is the history of the hundred feet that appeared in this era. And there is another branch, which is the history of Baizu that has not appeared. The leaves behind the branches can also represent the history of our defeat of the hundred feet and the history of not defeating the hundred feet. Because of choice, the world can be divided into many. ”

"You mean ......?" Thinking about it, Watergate asked.

"The world we live in, and the world in which our predecessors lived, can be seen as two different leaves on different branches, two worlds that are roughly the same, but with different subtleties. I paint on one leaf, how can another leaf have an impact? And this is the parallel world theory, which unravels the grandmother's refutation. ”

"Therefore, history cannot be changed, history can only be chosen. In fact, there is no reason for the predecessors to choose to erase their memories in order not to change history. ”

"Besides, erasing memories is not killing one's future self or others."

"What do you mean by that?" Here, Yan asked curiously.

"I think that the so-called man should not be defined only as Homo erectus. After all, someone can make themselves into a human puppet. Sticking to the flesh is narrow. So, my definition of a human being is: a being who can think about the past for the sake of the future. The essence of human beings is memory that can be thought. ”

"And memory, take this queen of Loulan, Sara, for example, who has no experience of meeting us, she is the stupid and incompetent princess that An Lushan said. However, after the changes of the past two days, is she still the same person she used to be? ”

"Erasing her memories of this time, what difference is this from what Baizu did to her? Playing with other people's lives and using others as puppets. ”

"Huh~~~~" With a long exhalation, Shuimen looked at Hitomi and exclaimed: "Are the future juniors so powerful?" ”

"Not really! There are not many like the old decay. Hitomi said lightly.

"Decayed? Why do you use this self-title? Yan asked.

"Personal preference, psychologically immature little girl in order to flaunt different." Hitomi Hinata buried herself in her own way.

"Okay!" Shaking his head with a smile, Yan didn't ask anything anymore. Because, in the eyes of Hitomi Hinata, he saw the meaning of being concerned.

"Although the world we live in is not the same world. But, as you said, there are similarities between the worlds. You don't care about the past, but we have to worry about the unknown future. Here, Mizuto said to Hitomi.

"It doesn't matter, it's your choice. You choose to forget, though. There is such a world that will choose to remember it. The future is not unknown, everything that is unknown is already predestined. Here, Hitomi thought for a moment and said, "If I were you, I would find a way to know all the options." Then, let your heart decide your choice. ”

"Really? I can't do that. Shaking his head, looking at the few people on his body who were getting brighter and brighter, Watergate was silent for a while. Then, he said "goodbye" lightly.

"Nope! Wait a minute! I haven't said it yet! Here, Naruto, who had been unable to interject, became a little anxious.

"Hmm!" Mizuto looked at Naruto calmly, he nodded and said, "We definitely have a chance to meet again, but not now." ”

"How is this~~" Naruto grumbled and walked a few steps forward, he said to the water gate, "I have a lot of things to say to you, if you don't say it now, you won't have a chance to say it!" ”

"One day, I'll listen to you." Mizuto said with an affirmative smile at Naruto.

"Big brother...... Big brother, are you ......" At this time, the sluggish Naruto finally reacted, he looked at the water gate, he had something in his heart but didn't know what he should say first.

"If I have a son, I'd like to raise him to be a ninja like you." Looking at Naruto, Mizuto said.

"I ......" couldn't say a word, and Naruto gritted his teeth and closed his eyes.

"Naruto! Perhaps, as you said, the town of Loulan will really be destroyed. Here, Sara, who didn't know the relationship between Watergate and Naruto, said to Naruto, "However, I still have the people of Loulan. I will definitely do what I have to do for them. Because, that's what Naruto you taught me! ”

"Hmph~" The corners of his mouth hooked up a smile, Naruto turned his head to look at Sarah, and he said sunnyly, "Yes! As long as you have firm perseverance, you will be able to do it! ”

Here, Obito and Kakashi say their last goodbyes. As for Hitomi, she looked at the two Hyuga brothers on the other side.

Eventually, the three of them turned into light together.
