Master gave me an exquisite heart, invincible in the world!

Chapter 880

"Back to the past...five years ago?"

Shidou couldn't help but frown. After all, five years ago was not a good time.

Even leaving aside the fact that Kotori became an elf at that time, even now, my memory of that time is still quite vague.

It was obvious that his memory had been tampered with, and this alone was enough to prove that many unimaginable things had happened at that time.

And now Origami, who was affected by the fragment, returned to that point in time……

“Don't think too much, Shidou. It's not that difficult to bring the origami back. After all, I was already born as an elf at that time, right? "

Seeing Shidao's face full of sorrow, Mu Qing spoke in time.。

“Although in terms of strength, I was only a dabbler at that time, but my head for thinking about the problem... there was no problem for the time being. If you have any questions, just ask her directly. She will provide help, including of course the recycling of debris.。”

“Recycling fragments... So Mu Qing, you were doing this five years ago?”

“There's nothing we can do about this, right? "

Mu Qing spread her hands.。

“After all, I am the only one who can do this, so I must do it... Ah, of course, the other me can also do this easily.。”

“……”

Although Shidou wanted to complain, "Isn't that all you?", he felt it was inappropriate and finally kept silent.。

“However, you should be very cautious about going back to the past. Although this world seems to have a [Conclusion] setting under normal circumstances, after all, there are existences like me now... so I still remind you. "

Mu Qing exhaled and spoke seriously.。

“Don't think about changing some things that have definitely happened, otherwise it may cause unnecessary butterfly effects... For example, you can imagine that when I first appeared in front of you and Tohka, my strength was only limited to the level of an elf. ? I'm afraid I'll be beaten up by AST……”

“……I probably understand。”

“Haha, this is not something you can do just by understanding it, Shido-kun... Just as Miss Mu Qing said, rashly changing the past will have bad consequences. "

Although Kurumi looked smiling, Shido felt a great pressure from this smiling face.。

“Okay, Sansan, don’t scare him anymore. Anyway, you will remind him later that it’s okay to be a little negligent... Besides, if you put so much pressure on him now, he will still need to complete more difficult tasks in the future.。”

“Oh Well. "

The girl shook her head, and the charming smile on her face softened a lot.。

“But as you said, Shido-san is indeed the most suitable candidate to use the Eleven and Twelve Bullets... After all, no one except him can possess such exaggerated spiritual power.。”

“Um. "

Mu Qing nodded.。

“After all, the first thing may only take half a day to complete, but the other... It is almost impossible to complete it in a short time, and only Shido's spiritual power can sustain the consumption for such a long time.。”

“The consumption of spiritual power... Do I still need to continue to have spiritual power while staying in the past time?”

“But Miss Mu Qing, if it takes a long time, do we have that much time to wait for Shido to find the so-called reinforcements? You must know that even if the Twelve Bullets are used, time in reality is still flowing as usual. "

Noting the problems existing in the battle, Kuang San raised his doubts.。

“Well... let me explain it in a way that you should be able to understand. First of all, the parallel world should not belong to the same world as this world, right? Ah, of course they belong to a small world. The small world is different from the world mentioned above.。”

“……What are you talking about...but maybe it's like what you said? Two worlds are not one world? "

Kotori was a little confused when she heard it, but she still echoed the answer.。

“In the absence of an observer observing both worlds at the same time, the time of the two worlds can be relatively static or relatively moving.。”

“What's the meaning?”

“This means that as long as we don’t observe the situation over there, time over there can be relatively static for us.。”

“……ha?”

“……What an interesting theory. "

It can be said that Kotori and Kurumi gave completely different reactions.。

“It should be analogous to 'as long as I don't travel to the past, then that point in time in the past is static', right?”

“Ah, yes! That's pretty much what it means... I always feel that your explanation, Sansan, is simpler than mine. "

Mu Qing scratched her head in embarrassment.。

“But after all, Shido does not belong to that world, so time there cannot be completely still. Moreover, when he contacts Kurumi here, the process of contact can be regarded as observation, which means that it will consume his own energy. Not much time。”

“It means we need to limit communication to save time, right? "

Shidou exhaled deeply.。

“It seems that we shouldn’t waste our precious time here. Miss Kuangsan, although I can’t completely trust you yet... but please do the following. "
