Because the O'Geland sisters came early, they also got a mobile phone from the window, and they also got their own "phone numbers".

Unlike modern times, Founder does not equip mobile phones in other worlds with SIM cards, on the contrary, the number here is bound to the mobile phone, that is, one number is a mobile phone, and it cannot be replaced.........

So don't think about dual SIM dual standby, if you want to open a small number, please buy two mobile phones.

The smartphone was very easy to use, and it was explained in Overworld text, so it didn't take long for Ogeland and his sister to learn how to use their phone.

"Sister? Sister? Can you hear me? I hear you, huh? ”

"I can hear it, I know it very clearly!"

Hearing the clear voice of his sister in his ears, Ogelan's legs shook with excitement.

Indeed, telecommunication is not uncommon in the Overworld, such as teleportation and breeze, which are often used by mages. However, these methods also have many drawbacks, such as the distance limit of the teleportation technique, and the breeze technique can only transmit communication within one hundred and fifty words——— from a certain point of view, this is also a magical version of the telegraph from another world.

However, each of these methods has a serious flaw, which is that it requires at least one of the two parties to communicate to be a mage, and must be able to use the spell. This is also the reason why even with magic, the nobles still insist on using letters to transmit information——— after all, they are not willing to use the mouth of a third party for many things, and most nobles do not actually use magic, so if two nobles who do not understand magic want to contact each other, then there is no way to use magic.

Now, however, the problem is solved!

Even if we haven't completely figured out what the functions of this "smartphone" are, this alone can make two people who don't know magic communicate anytime and anywhere, and it is enough for Ogeland to see the prospects and profits!

The important question now is where exactly these phones can be used, what is the effective distance and range, and what are the limitations.........

And if you want to know the answers to these questions, then there is only one way.

"Let's go to the booth of the Heavenly Dao Palace!!"

Holding his phone, Ogeland quickly made a decision.

Unlike other places, when Ogelan took his sister to the booth of the Heavenly Dao Palace, it was already crowded with people, and as far as the eye could see, there was a black oppression everywhere.

The booth of the Heavenly Dao Palace, Founder, completely used the drawings designed by Nanorka from Franke's workshop. At the top of the center of the booth, a crystal tower was suspended, and on both sides there were three areas with three pure white walls, each with different styles of decoration, to set off their themes.

The entire Tiandao Palace booth is divided into three aspects: "communication", "information processing" and "entertainment". Among them, the "Communication" booth mainly introduced the whole process of how mobile phones are used, how large their scope is, and how they work through pictures and text descriptions. The text descriptions and images used are also quite easy to understand, and even Ogran, who doesn't know much about magic, has a certain level of understanding of the phone in his hand after reading the schematic diagrams.

"Therefore, this mobile phone can realize the communication function within a certain range by interacting with the crystal information......... Well, I see, I see........."

Frowning, Ogran took a closer look at the crystal tower suspended in the air. In other words, if you want to use this magic item called a mobile phone to communicate, you will have to spend money to build a crystal tower......... That's a tricky one. Maybe those big cities don't have to worry, but in some remote areas, it is not profitable to spend a lot of money to build such a crystal tower, let alone prevent the crystal tower from being attacked and destroyed.........

Moreover, the crystal tower cannot be moved, and in large cities, it can also be equipped with patrols, and if it is in a remote area, I am afraid that it will need to hire people to protect it, which is another lot of money......... Maybe it can be shared with the garrisons and fortresses of the border cities? They must be in need of this crystal to communicate with the capital, and if so, maybe they can keep the price down, and they can also get them to send someone to protect it?

As a businessman by nature, O'Grande immediately began to think about the profits and how to make them as soon as she calmed down, and she was sure that this invention would change the entire continent! Whether it is economically, military, or in terms of cultural exchange!

After all, from the current point of view, there will be no delay in using mobile phones to send messages, whether it is communication or writing letters! Gone are the days of writing a letter and sending it on the way, worrying that the letter would be lost on the way back and forth, or that it would be lost by bandits!

Of course, they can send urgent letters directly through the magic array, but the problem is where do ordinary people have so many urgent letters that need to be sent? In the case of O'Grande, she wants to share with her friends that the flowers in the garden have bloomed beautifully recently, does this need an urgent letter?

Not to mention that magic teleportation is expensive!

However, with a mobile phone, none of this is a problem anymore! She can send messages anytime, anywhere, and she doesn't have to worry about missing her letters, let alone problems!

After a busy day's work, she can drink afternoon tea comfortably in her own garden, while chatting with her friends thousands of miles away by voice or video, of course, she can also use the "shooting" function of the mobile phone to take pictures of the scenery she sees anytime and anywhere, and share it with other friends.........

Just thinking about all this, Ogeland was already a little impatient!

This was only what Ogeland had in mind from the perspective of a merchant and aristocrat, and it was a different picture in the eyes of the military-born military attachés and high-ranking politicians.

If nothing else, if you think about it, if the fortress on the border is attacked, you can get the information immediately after a second, instead of waiting for days and then watching the messenger appear in front of you on a dying horse to report the attack on the fortress......... What does this mean?

Soldiers' speed!

With such a magical prop, many generals don't even need to rush to the battlefield in a hurry, but only need to observe and give orders through their mobile phones, and they can command the battle!

And for those politicians, this is just as important, their own information, friends' information, enemy information——— who wants to stab themselves in the back, if you can know this kind of thing for the first time, isn't it more convenient than waiting for the other party to return to the nest when you hear the report? Moreover, with such a prop, they don't have to worry about leaving evidence such as letters when contacting henchmen who are far away!

The second "information processing" booth was not a mobile phone, but something that looked strange in O'Grande, it looked like two rectangular black stone slabs connected to it, and next to it was written that this thing was called ——— personal computer?

In O'Grand's view, it is like an enlarged version of the mobile phone, in fact, Founder does not plan to directly popularize computers in this world——— the development of the main world is different from other worlds, the mages here explore the magic web to study magic and do not need computers to help them carry out spatial calculations, you must know that this requires a complete computing system, and the computing system of the main world is completely different from the computing system of the Founder world, so after thinking about it, Founder decided to directly treat the computer as an "office supply" and use it as a printing of documents, inputs, and a wide variety of to-do lists and financial statements and the like......... At least it's safer than a record written on paper.

There were more businessmen at this booth, after all, businessmen were able to find out how important the financial statements were to them a few years ago——— and they knew that their financial statements were piled up higher than a mountain in the warehouse, and if nothing happened, they would even send someone to rummage through it for many days, just to find a small contract from it. And now, with the help of a computer, they don't have to waste time anymore!

Don't worry about your warehouse being burned down.

After looking at the "computers" displayed at the "Information Technology" booth, Ogeland took his sister to the third booth, which was the "Entertainment" booth.

Now she really wants to figure out, how is this stuff going to be entertained?

So far, through the "Communications" and "Information Technology" booths, Ogeland has admitted that this time Fang Zheng has brought her an absolute surprise, but even so, she can't think of how to entertain with these things......... After all, entertainment and games are completely different from those that used to live and work.

The third booth was very crowded, but most of them were young people, and it was clear that young people were more interested in entertaining games. I saw them huddled in front of the stage, cheering from time to time, and even waving their hands, as if they were watching a duel.

Could it be that the so-called infotainment is a duel?

Duel with your phone?

Ogland felt a little confused, but she squeezed through, and when Ogland and her sister squeezed to the front with their slender size, they finally saw the scene in front of them.

And when they saw the scene on the booth clearly, the two were stunned.
