Makise Kurisu also understood what trouble they were having.

But she was still a little puzzled why they were looking for themselves.

"Isn't there a replacement for Time Machine?"

"Although there is not much energy, according to your purpose, you should also go to the past together."

At 880 when she was talking about this, she felt a little uncomfortable in her heart.

Why are these two people going back to the past together?

the most important is.

This time, after returning to the past era, they can no longer take the time machine to return to the future.

In other words, they need to live together in the past together, and then until they come back to this time?

This is no longer the so-called life-long relationship.

This is simply a relationship that truly lived a lifetime together!

If it is not intellectually clear, if you add yourself, it will only make the timeline more chaotic.

Makise Kurisu even strongly demanded that he be brought along.

Originally, she was only interested in research in this era except for her father.

Now her relationship with her father is severed, and the research papers on the time machine that have been prepared for several years are also suspended.

She didn't seem to be able to continue to devote her energy to anything, and felt that everything was troublesome.

It might be a good experience if you can experience time travel and live with this mysterious void.

Unfortunately, this is not the case.

"Since it's been decided, what are you still coming to do with me?"

Makise Kurisu adjusted her mood and said coldly.

"Isn't it here to say goodbye to me? It's really an honor.".

Makise Kurisu's mood was obviously a little unhappy at this time.

Su Yue didn't care about her poisonous tongue at this time.

After all, he knew very well what a tsundere's mood was like at this time.

But this time he really couldn't bring his assistant.

If there was a chance to spend a lifetime with her, he could not ask for it instead.

But now there are two people who are out of the original timeline.

According to his calculations, after returning to the past, according to the original history, it should be no problem to send him and Awane Lingyu back to the original time.

But if you add another Makise Red Riki.

There is no guarantee.

And this Makise Red Risu who has survived the time of death is a rather special existence in this unchanging β world line.

After all, the condensing result of the β world line appears to be "death of Makise Kurisu".

As for Makise Kurisu who is still alive and well, will there be any accidents in the future.

These are all things that need to be avoided.

In other words, the surviving Makise Kurisu is now the focus of the will of the world on this world line.

It is already quite dangerous for people like them who come from the future to continue contacting her.

If at this moment she suddenly disappeared from this point in time and went back to the past with them.

Then it is likely to cause the failure of the change of this world line.

Everything before that will be lost.

So Su Yue couldn't accept this ending.

"Hong Liqi, I actually came here to ask you to help calculate the space coordinates."

"coordinate?"

Makise Kurisu frowned and repeated the word.

According to her own paper on the time machine, she mentioned the problem of positioning the spatial coordinates after passing through time.

However, because my paper is still based on theory, there is currently no fixed result on how to calculate the spatial coordinates after crossing.

"Yes."

Su Yue explained.

"You should also know that after the real time machine travels through time, if the coordinates are uncertain, it will send you to the location where you were before."

"But the definition of everything in the world is [relative]."

"For example, the'past' is for the present me, but today is also the'past' for tomorrow's me. This is the so-called reference coordinate."

And one of her guesses mentioned in Makise Kurisu's paper is.

Maybe when human beings travel through time in person.

It is not only time that travels, but also space.

The specific way of positioning time itself depends on how much time has gone backwards or forwards.

But the space is different.

If the space after crossing is not positioned in advance.

Then after you pass, you will appear in the "place" where you were before.

This place is not the original place recognized by normal people.

It is the spatial coordinates for this world, even this planet and even the universe.

After all, the earth is constantly in motion.
