Taking pictures is just one of the functions of smartphones......

Taking out the mobile phone from his pocket, Xu Zheng demonstrated to the two kings the use of mobile phones on the other side of the earth, although the world of miracles has not yet been connected to the Internet, and the words of the two worlds are not the same, but with the understanding ability of the two kings, they quickly learned the basic role of the mobile phone as an "alchemy tool" from Xu Zheng.

In the face of the many functions of the mobile phone, the lion's roar only thinks that the mobile phone is very convenient to be able to chat remotely, and then there are those game applications, which are much more interesting than the traditional games in the orc king's court now, and what Augustine can see is completely different from the lion's roar.

If, as Xu Zheng said, the mobile phone can be used for remote calls in a timely manner, the function of this "alchemy prop" is simply too great! Merchants separated by two worlds can communicate with each other anytime and anywhere, and the transaction of many bulk commodities does not require buyers and sellers to travel long distances when discussing transactions, which can not only ensure the safety of merchants, but also save a huge caravan consumption on the way.

Moreover, this kind of remote call is only one of the uses of mobile phones, according to Xu Zheng, people can also achieve rapid exchange of information on mobile phones, such as if there is a natural disaster in the northwest of the kingdom, the officials there can immediately transmit the news back to the royal capital through mobile phones, and the kingdom can also use the fastest response in advance to complete the disaster relief and discuss the post-disaster reconstruction work, there will not be like now, waiting for the messenger of the kingdom to quickly convey the news in a few days and nights......

"Such a sophisticated alchemy tool, even if it is worth a lot of money, the kingdom will order thousands of eight hundred!"

Augustine made a decision without thinking about it, and said to Xu Zheng: "In this way, if I have anything I want to communicate with Prince Xu Zheng, I can contact him directly with my mobile phone!"

"The premise is that there is no Internet...... Xu Zheng felt that even explaining the knowledge of information engineering to Augustine in detail was futile, shrugged his shoulders and smiled: "If you talk at close distance, we can use walkie-talkie, this thing has no technical content, but if you talk at a distance, there are still a lot of technical problems that need to be solved." ”

"But as far as I know, you and Her Royal Highness the princess have already used this thing!" Augustine thought that Xu Zheng wanted to sit on the ground and raise the price, but Xu Zheng dialed Lilith's phone number in front of Augustine, but on Lilith's side, the mobile phone did not respond at all.

"It's not like you can talk long distances with your mobile phone, and there is no satellite or mobile phone coverage in the world of miracles...... You don't think that it will be easy for Hell to realize this 'innovation' of remote communication in the world of miracles, right?" Xu Zheng glanced at Augustine and said, "At least His Majesty the Demon Dragon King will take a trip to the sky with something weighing a few tons, and then build something similar to the 'Mage Tower' on the land of various races......"

"In other words, the content of the mobile phone call should be heard by those mages?" Augustine frowned slightly, but Xu Zheng glanced at the goods strangely and said, "Where did the mage come from?"

"Didn't you say that you want to build a mage tower? I seem to have understood the operation of the mobile phone, that is, the people on the ground talk, and it is transmitted to the thing brought by His Majesty the Demon Dragon King in the sky, and then the mage tower on the ground receives those signals from the air, and the mages of the mage towers decipher it, and then relay it to the person who wants to talk......"

His Majesty the King talked eloquently, but Xu Zheng had a feeling of not knowing it, it was the first time he had heard that the transmission method of mobile phone signals was like this!

The conversation between the three of them did not shy away from others, and Xu's father and mother couldn't help but be happy after listening to His Majesty's explanation, and even Linglong couldn't help muttering in a low voice, "It's terrible to be uneducated".

"It's not what you think it is!"

It took a long time for Xu Zheng to come back to his senses and said to Augustine: "This technology was passed on from my hometown, there are no magicians in my hometown, and the 'magic tower' I said before was just afraid that you wouldn't understand, and the accurate name of that thing should be a signal tower or a ground base station or something!" It only needs a few simple workers to maintain, and there is no need for professionals to be stationed at all, a small signal tower can completely cover a large area of calls, in my opinion, the entire orc royal court can solve the mobile phone signal problem here, the king is larger, maybe one is not enough......"

Seeing that Augustine was about to ask some more technical questions about mobile phone calls, Xu Zheng decisively interrupted His Majesty's curiosity and said: "I am not an expert in this area, and the problem of building a signal tower will be handed over to a professional construction team when the time comes!"

"Are the alchemists from your hometown?" Augustine said, "Can the alchemists of the kingdom learn it?"

"It's good to have a thirst for knowledge, but the development process of the two worlds is different, even if you go, I'm afraid you won't be able to learn too much, but instead confuse your own original technical expertise, that's not appropriate......" Xu Zheng smiled: "Besides, the most cutting-edge knowledge you receive now is the sixth grade textbook of primary school...... And these technologies are not in the realm of 'primary school students'!"

"That's right, I still understand the truth that greed is not rotten!"

Augustine nodded thoughtfully, even if the primary six textbook is on the side of the miracle world, those nobles and magicians in the royal capital have only just come into contact......, and a lot of the knowledge in it has not yet been understood!

Just like a few months ago, even multiplication formulas would be regarded by them as advanced "technology cheats"!

"So mobile phone calls and the popularization of computers these things I just say hello to you in advance, and when the satellite goes to the sky to promote these products, we will definitely talk about it, but it is not an overnight thing to complete such a big project, I think before the next six-pole meeting, it can be done well, it is already a very fast progress!"

"How many years will it take?" Augustine looked at Xu Zheng in surprise and said, "Then does this project require the participation of the kingdom and the orc royal court?
