Two days passed in a blink of an eye. Some people were panicked about the fireball that took off outside the city two days ago, thinking that something had happened.

However, because a notice was posted at the entrance of the city hall that afternoon, indicating that this matter was an experiment of the Castlevania itself, not a war, so don't worry.

The literacy rate of Castlevania is now very high. Even if some older people are illiterate, the young people around them can read it to them.

The same goes for the saying, the higher the level of civilization, the better the politeness of the people living here.

So many people understand the causes and consequences of this matter. When they see that it has nothing to do with them, they don’t care much.

Just as he was discussing things with Alisa on the facade of the study in the main castle, Nitia suddenly shook her head.

"What's wrong?" Alisa asked.

Niteya stretched out her finger and pointed to the crowd of people in the square opposite: "It's too inefficient. If you rely on posting notices at the door of the city hall to notify you every time you have something to do, this kind of thing will inevitably happen."

"It's normal. After all, there are not many things that require notifications, so there is no need to..."

"It's very necessary! First of all, it's too troublesome to squeeze here in such a large number of people. First, it's a problem of information transmission, and second, it's a problem of transportation." Niteya shook her head, "Now the surrounding city walls have basically been demolished almost the same. The city is getting bigger and bigger, but transportation is getting more and more inconvenient."

"Isn't the sales of bicycles and motorcycles OK?" Alisa asked back, "And the automatic carriages are OK, but after all, they are too expensive and most people can't afford them..."

Niteya shook her head: "No, I need to develop something new?"

"What?" Alisa was curious.

"The first thing is the traffic problem. It requires larger cars and can be equipped with many people. Run in the city according to a fixed route, and multiple platforms are set up along the way, and each platform can be brought or taken off. This can relieve the pressure on some people who cannot afford motorcycles and will not ride bicycles." Nitia replied.

"This problem should not be big, the technology is ready-made." Alisa nodded, "But how to solve the other one?"

"The form of notice can be changed. For ordinary people who are interested, they can write different information on paper every day and then deliver it to their doorstep. They can learn the information they want to master without leaving home." Nitia lit her lower lip, "As for those who are rich, they can consider improving their current phone and using signal towers to broadcast the information in sound every day..."

"Is this good for the development of Castlevania?" Alisa didn't quite understand.

"The benefits are great." Niteya nodded, "Leave this question to me, how are you doing there?"

"She agreed and can set out tomorrow." Alisa replied.

"good!"

...

The two of them didn't talk much, so Netiya returned home.

Now in the Castle of Demons, she no longer lives alone. She bought a big house because she brought her family over.

Usually when Selena is not around, she basically lives with her family.

Now that the parents are old, the two sisters have become middle-aged women.

Although she herself had no feelings for this, under her mother's strong request, Nitia would still return home to live with them when she was fine.

But even after returning home, Netiya usually doesn't chat, but instead looks at something with a transparent board.

This thing is the latest invention of Nitia, which was originally Decao, and the monitor.

It looks like a two-centimeter-thick transparent board, but it can display a lot of things on it, and can connect many things in the laboratory to make some simple operations.

When he got home, Nitia lay on the sofa and turned on the monitor.

At this moment, a magic array was displayed on it. The satellite launched this time, Nitia also used dark energy connections to test the limit distance of this communication method.

The good news is that it was connected smoothly, and the transparent board shows the pictures taken by the latest developed cameras.

The bad news is that it is still impossible to test the limit distance of such communication.

The latest camera developed is completely different from the one at the beginning. The first camera that Nitia invented can only take a picture in one minute.

The latest developed one can take two hundred pictures in one second, yes, two hundred pictures in one second.

Then if it is displayed at a speed of 200 images in a second, the things you take will become dynamic.

What Dikao said at the beginning, Netiya is realizing it bit by bit.

After a while, a huge green sphere was shown on the screen, with white mist flowing slowly.

The whole picture seems to move very slowly, and the huge sphere that occupies three-quarters of the picture is pitch black.

I can't see the sight at first sight, but I can see the shining starlight and a stone that passes by quickly.

Seeing this scene, Nitia was a little surprised and excited.

Dikao had said before that they lived on a huge sphere and now, it seems to prove that his words are true.

In other words, the dark space that can’t be seen at a glance is the so-called universe?

Nitia turned the camera while thinking, as if she wanted to find something, but unfortunately, there was a dark space around her that could not be seen at all, without any clues at all.

Feeling a little bored, Nydia turned the camera back again and looked at the planet in front of her.

Suddenly, as if I had discovered something, I reached out and clicked on the monitor, then slid my fingers and the picture instantly enlarged.

After thinking about it, he gently pointed his fingers on his temples: "Olilyn, bring me a few big pieces of paper."

"Okay, how big is it?"

"The biggest in the laboratory!"

"Yes! You can wait!"

...

"Nitia, it's time to eat!" My mother's voice sounded at the entrance of the restaurant.

"Well, you guys eat first, I'll come later!" Niteya, who was lying on the sofa, agreed without looking back.

"Hurry up, it will be cold in a while!" The mother also knew that she was very busy, so she didn't urge her too much.

As the regent of the current Vicardman Commonwealth, Niteya actually manages all the surrounding countries, which makes Rayga more or less uncomfortable.

Although his title of Honeysuckle Grand Duke is still retained, he is actually almost the mayor of the Principal of the Principal of Verbalu.

Although the emperors of all countries are retained now, they are actually mayors or district mayors, and they do not have as much power as before.

After a while, the knock on the door rang out and the housekeeper went to open the door.

Olilyn walked in slowly.

Now Olilyn is dressed similarly to Succubus in her dress, with her hairy ears on her head and her tail sticking out from the group. No one said anything when walking on the streets of the Devil Castle.

"It's Olilyn! Come and sit down and have dinner together!" Mother Tiona greeted warmly.

She still has a good impression of this orc girl.

"Okay!" Olilyn agreed without hesitation, and then handed the roll of paper in her hand to Nitia: "Your stuff."

"Yeah." Nitia stood up and spread the paper open. A breeze blew out of her hands, blowing the paper completely on the ground.

This piece of paper is very large, with a length of more than four meters and a width of nearly three meters. It is generally used to draw large design drawings.

Then Niteya let go of her hand, and the monitor in her hand slowly floated up and hovered over the paper.

The next moment, the picture on the monitor was printed on the paper, and the Lei Jia next to it could see it, it should be a map.

Then Niteya opened the second piece of paper and printed another map on the monitor.

Nitia waved her hand gently, took back the monitor and both sheets of paper and the space ring, turned around and walked outside.

"Nitia, are you not eating?" Tiona asked.

"Just keep it for me, come back to eat later!" As he said that, Nitia had already opened the door and walked out of the room.

"This kid..."

"Forget it, don't worry about her..." Lei Jia waved his hand, "Even if the City of Demons system is advanced, sitting in this position will still keep your feet on the ground when you are busy."

...

Netiya, who walked out of the room, reached out and pointed on her temples: "Enjeli, can you come to the study in the main castle? And Alisa, I have something to tell you."

"Okay, it'll be here soon!" Enjieli agreed.

"I'll prepare now!" Alisa agreed, and then ordered the human maid at the door to prepare for tea.

...

After a while, Enjeli and Nitia arrived at the study in the main castle one after another.

Alyssa poured them a cup of tea: "What's wrong?"

Nitia waved her hand and two pieces of paper were pasted on both walls: "This is the map I took today, this is the whole picture of the entire forest."

Speaking of this, Niteya pointed to another piece of paper: "This is the scene after enlarging this side!"

When the two saw that there were several cities, the largest city in the middle, you could even see people huddled on the street.

This itself is not a rare thing, but it seems that each of these people is surrounded by a wild beast.

Some are big and small, some are running on the ground, some are flying in the sky, some are following, and some are staying on the shoulders of humans next to them...

"No doubt, this should be a country!" Netiya turned her head and looked at the two of them, "and, it may be a country where humans and beasts coexist."

"Well..." Alisa looked, "From the map, this geographical location seems to be..."

"Yes, it's very remote, and not far from the sea." Niteya nodded, "so it's basically certain that we don't know, and it's very likely that they don't know one of our countries either."

"Then you mean..." Enjieli was a little confused.
