Although the technology in this world is not particularly advanced, there are some theories that are quite useful.

Of course, in the eyes of people in this world, those theories are absurd, and can even be said to be nonsense.

The guy who created these theories is probably also regarded as a psychopath, either incognito, or isolated, or even directly imprisoned in a mental hospital.

However, these theories that are not worth it solve the problem that I have been unable to solve for a long time.

"Measurement Equation for Spatiotemporal Positioning".

At present, it is 99% complete, but the remaining 1% has not been established.

And now, I finally see hope.

Once this equation is complete, the space-time barrier will be completely useless, and I can reach any world I want.

Even, the "origin".

While it would have been quicker to bring these books back and study them with Farstar, I can't wait.

Get it done now!

"Well, what the hell are you doing?"

I've been reading it for a long time, and Dongfang Yao is still writing over there, not paying attention to anything else at all.

"Why don't we go over and have a look!"

Honju Kosuzu built yì road.

"Hmmm......"

Barnyard Aqiu felt that they shouldn't get in the way of Dongfang Haruka, but she also really cared about what the other party was doing.

Honju didn't think about it that much, put on her glasses and tiptoed over.

"Hey!"

Barnyard Aqiu wanted to call out to this guy, but in the end he held back. She hesitated for a moment, then quietly followed.

Seeing that she had also come, the girl turned around and smiled mysteriously.

The two stood in front of the table, but Dongfang Yao still didn't notice their arrival. I saw him flipping through the pile of books next to him, and then he seemed to have encountered some difficulty, scratching his head there, and finally I don't know if he suddenly figured it out, and picked up the pen to write a round of fierce writing.

And so on and so forth.

Those books Ju Xiaoling has also read, they are all foreign books flowing in from the outside world, and they seem to be about science. However, because it was outside knowledge and extremely profound, she didn't understand what it was talking about at all.

As for the others, they should be books that she has only recently received and has not yet read.

"No, no, if we take into account the existence of the anti-universe, the spatial measure should need to be reset. ”

Dongfang Yao lowered his head and chanted there with words, as if he was discussing a problem with someone.

The two girls looked at the notebook in his hand, and it was full of letters, numbers, and many unintelligible symbols, and they couldn't make out what it was.

Honju looked at it for a while, and there was a slight eyebrow.

"What kind of formula does this look like!"

"Formula?"

It was the first time that Aqiu had heard this term! He couldn't help but turn his head and look at her in surprise.

"It's a modern formula for quantity calculation, and it is said that it can solve many problems that cannot be solved by ordinary methods!"

Honju Kosuzu has read a lot of books on natural science, and in them you can often see similar formulas, but it is definitely not as complicated as the one in front of you.

It was beyond her comprehension.

The girl's instinct was to tell her so.

"And what are you going to do with this thing called 'formula'?"

Barnyard Aqiu still doesn't understand much, but he thinks it's more important to figure out Dongfang Haruka's purpose.

"I don't know. ”

Honju Xiaoling shrugged helplessly, she can read the books of the present world, but it doesn't mean that she really understands the content!

It's like knowing that one plus one equals two, but why is it equal to two?

"Really?"

After talking for a long time, I still don't understand anything!

"It's better to ask Lord Dongfang directly!"

Rather than thinking about it here, it is quickest to ask for your own answers.

"No, you can't. ”

This time, Barnyard Aqiu reacted a little faster and immediately stopped her.

"Don't you see that Your Excellency is busy right now, how can you disturb him?"

"But ......"

"Nothing, let's go about our own thing!"

Not allowing her to make other comments, Barnyard Aqiu turned around and dragged Motoi Suzu away.

Seeing that things had basically been arranged, Barnyard Aqiu sat for a while and then took his leave and went home.

Before leaving, she repeatedly told Honju Xiaoling not to run to disturb Dongfang Yao's work.

The girl could only agree.

But as soon as the other party left, Motoju Xiaoling immediately got up and wanted to run over.

"Where do you want to go?"

The barnyard field Aqiu, who thought he had left, suddenly came out again, looked at her with a worried look and asked.

"I ...... I'm going to get ready for lunch!"

Although she was a little upset when she was taken aback, but thinking that her parents were about to return, Motoi Xiaosuzu thought that she was indeed going to make lunch.

Finding that she really ran into the inner room in a hurry, Barnyard Aqiu glanced at Dongfang Yao again before retracting his head.

This time it's really gone.

When Motoju Xiaoling heard her parents' shouts and came out of it, she found that Dongfang Yao was no longer there.

The books were all gone, and some money was left on the table.

This is what you need to borrow a book.

"Are you gone?"

Dongfang Yao has been here a few times, but today's table xiàn is the strangest, which makes Motoju Xiaosuzu a little confused.

"Little Bell, come in for lunch!"

When her parents saw that she hadn't come in for so long, they started calling her.

"Ah, okay. ”

The girl couldn't figure it out, so she put the money away and ran to eat.

============================= divider =============================

When I returned home, as soon as I stepped out of the "Crossing Gate", I heard a noise that could not be stopped from afar.

Hey, why is it so lively? Is everyone back?

"The Master is back. ”

The light spotted me at once, and the sound suddenly stopped, and then the rumbling footsteps came towards me.

"Welcome home. ”

The little ones who were running at the front pounced on me and hugged me tightly.

"When did you come back?"

I asked with a smile as I stroked their little brains.

"It's been a long time coming!"

Even lunch was already over.

"Brother, why did you come back so late?"

Otonari Chiba pouted and asked, if you don't go to see the mermaid with them in the morning, and you can't see him when you get home, it feels like you deliberately didn't go with them.

"I went to return the book, and I stayed there for a while, that's why it took so long to come back. ”

"Is it Suzu?"

"Hmm. ”

"Well, forgive you!"

The little girl put her face on it, rubbed it on the other party a few times, and said.

It turned out that she didn't deliberately hide from herself, and she was in a much better mood immediately.

"You guys are still the same, and people who have a good relationship are jealous!"

The succubus crossed his hands on the side and said with a smile.

This familiar scene calmed her mood a little down due to the ups and downs of encountering the new environment.

"Well, you're here too!"

Although surprised by her arrival, I smiled and nodded my head in hello.

"Aren't you happy to see me?"

"Sort of. ”

After all, I can still talk to her, and her personality is relatively free.

"Well, really?"

Originally, he asked first, but the other party answered so simply, which made the succubus a little embarrassed.

"What about us, what about us?"

Seeing that the other party only greeted the succubus, Marisa quickly jumped in front of the man.

"Alice and I just came back, too! Why don't you say hello to us?"

You can't do it differently! Otherwise, you're going to get angry.

The girl's eyes clearly illustrate this point.

"Hmmm......"

I looked at her with a very serious expression.

"You've gotten thinner. ”

I didn't expect such a thing to come out of the other person's mouth, and Marisa couldn't help but panic a little.

"Cause...... Because the things in the Demon Realm are not as delicious as here!So, well, that, I ate a little less, and of course I lost weight. ”

This stammering explanation aroused Alice's strong dissatisfaction.

"Marisa, do you despise my family's cooking, and if you don't like it, why do you eat so much?"

The girl pressed forward step by step and asked with a cold face.

Shanghai and Penglai had already taken out their spears and swords and aimed them at Marisa.

"No, no, I didn't mean that. ”

"What does that mean?"

"That's it, that ......"

"It's really a contempt!"

Taking advantage of the excitement of the children, I walked to the succubus with a smile.

"Your disciple is still so interesting!"

"Where, she's still tender!"

Faced with this guy who single-handedly caused the situation in front of him, the succubus rolled his eyes angrily.

"How's it going? How do you feel about being here?"

Reaching out to make an inviting gesture, I walked side by side with her towards the house.

"Well, it's so-so!"

The succubus deliberately pretended to be very bland.

"It's just that every time I come back, I always feel that a lot of things have changed! ”

"Only older people will sigh like this. ”

"I'm not young. ”

"How big?"

"Secret, secret. ”

They took the succubus to visit the castle, and in the evening, of course, it was a regular banquet.

It wasn't until the dead of night that a bunch of drunken guys were moved back into their rooms.

The other children had already gone to rest early.

I guess I'm dreaming right now!

After making sure everyone was asleep, I vanished from the castle.

When it reappeared, it was already on the other side of the island.

In front of me was a huge lake with a radius of ten kilometers.

I'm right in the middle of it right now.

The calm surface of the lake suddenly became turbulent, and a crystal building in the shape of a quadrangular pyramid emerged from the lake.

Suddenly an entrance appeared at the top of the crystal tower, and I turned and flew in.

Walk through a long hexagonal cloister and you reach the center of the tower.

Countless sky-blue hexagonal reflectors are closely connected together, forming a huge spherical space.

There is no light source, but it is as bright as daytime.

In the center of the space is a circular metal platform.

The platform is full of various instruments, and a small machine is busy.

"Chief, you're here. ”

Seeing the people who came in, Yuanxing hurriedly put down the work in his hand and went up to greet the other party.

"The 'core' is still working properly, right?"

This is the most secret place on Hades Island, it is the center of this world, and it also controls the operation of sub-worlds such as the "Extradimensional Space".

"Yes, a qiē is normal. ”

Far Star led me to the platform.

Looking at the dazzling rows of counts on those monitors, I nodded in satisfaction.

"Suspend this work for a moment, I have one more important thing for you to do. ”

I pulled out a large pile of documents from my body.

"Oh, is that the blueprint for a new type of space?"

"No, it's the space-time positioning equation. ”

"What?"

The news was so shocking that Far Star's body even shook violently.

"Have you finished it?"

Could it be that his master has succeeded in the operation that would even make its program chaotic?

"No, it's just a little bit close. ”

If it could have been done so easily, it wouldn't have taken me so many years.

"These things are the key to the final step, and I hope you can do your best to finish her. ”

It should be much faster than I am.

"Yes, I will definitely not disappoint you. ”

Yuanxing replied loudly, and even the mechanical sound without a little fluctuation showed a lot of fluctuations.

"Then you'll take care of the rest. Once it's done, it's ready for use. ”

I tried my best to figure out what's going on in the outside world.

"Understand ......"
