"Nine years old, it will take another nine years to become a real adult, and there are still nine years to study, what are your hobbies?"

Peravien nodded slightly, at the age of nine, no matter how much Matthias learned before, there was still a lot of room for improvement.

"I've made my own batteries out of materials to power toys, and I want to see what I've made become useful rather than a toy."

Matthias had a look of longing on his face, and he very much wanted to be a useful person.

"Oh, then I'm going to have to take a good look at your abilities."

With a smile on his face, he nodded to Wang Yan and said that he would test Matthias, no matter what the result was, Pelavien was quite interested in Matthias now.

"Then Mia and I went to contact Melvin first, and the remote video communication thing hasn't been done yet, so I don't know if it will work."

Seeing this, Wang Yan nodded and said goodbye to Peravien, Mia encouraged Matthias, and also left with Wang Yan, this laboratory is Peravien's exclusive laboratory, and Mia has to find another place to set up a video communication point.

After about an hour, Mia's equipment had been assembled, located next door to Peravien, and Nibel was also very concerned about it, and took time out of his busy schedule to go to the communicator, wanting to know if Mia could communicate with Melvin on video.

Different from ordinary communicators, the instruments used for video communication are very huge, and the center of the circular arrangement of instruments is a circular projection device, which is used to project the figure of the other party's communicator, even if it is thousands of miles away, you can see the person on the other side through this method, and you can directly talk to the other party, and Melvin also has the same device, and you can also see the situation here in Mia.

Of course, these are the situations in the game that Wang Yan knows, and now that the various machines of the communicator have just been assembled and powered on, it is still unknown whether the video communication can be truly carried out, whether it is Mia or Wang Yan, there is no guarantee that this communication can be truly successful.

Before the video communication, Mia and Melvin had a communication, and finally received Mia's contact, Melvin breathed a sigh of relief, after talking for a long time, he heard that Mia had assembled the video communication, and he said that he would immediately go to debug the communication device on his side.

About five minutes later, the video communication device in front of Wang Yan and the three of them suddenly flickered, Mia pressed the controller in her hand, and then saw a light curtain rise from the projection device, until it rose to a height of two meters before stopping, the messy image was projected, and Melvin could be vaguely seen in a hurry, after all, there was only one person on his side, and he had to control many, many things.

"Hey, can you hear me?"

About half a minute later, the projection picture gradually became clear, and then Melvin's voice came directly from the projection, Melvin's figure holding the controller was also revealed, after seeing the figure of Wang Yan and the three of them displayed in the projection, Melvin who was far away in the laboratory of the Elytra Research Institute of the Seven Gods was full of joy, and the three of Mia were also smiling, this way of communication was very magical, even Wang Yan was seeing it for the first time.

"Yes, good afternoon, brother."

Mia stepped forward to the projection device, Nebel on the side smiled at Mia who was talking to Melvin, he was very satisfied with this result, although he can only contact the Elytra Research Institute of the Seven Gods, but he believes that after the initial mass production in the future, all departments of the Imperial Capital Army have installed this kind of image projection device, even if they are thousands of miles apart, they can also communicate without hindrance, and even hold meetings with multiple parties, which greatly facilitates information communication.

"It's good if it's successful, you and I have to remember the band at the moment, don't debug it for so long next time you make contact, wait until I turn off the projection device, and you take the initiative to contact me again to see if the band can be effective."

Before the end of communication, Melvin's voice was heard from the video.

"Okay brother."

Mia nodded in response, and the image in front of her dissipated a few seconds later, because Melvin had voluntarily turned off the affected communication.

Mia took a deep breath, chose to control it on the console on the side, and chose to contact Melvin after entering the band on Melvin's side, and it was about half a minute later that the projection device lit up again, and Melvin's figure was revealed again: "Mia, we succeeded!" ”

"Yes brother, we succeeded!"

The corners of Mia's eyes were red, she could hear the joy in Melvin's voice, and she was also very happy in her heart, and she was very happy to be able to help Melvin.

"I'll come." Nebel, who was standing on the sidelines, stepped forward to Mia's side and chose to communicate with Melvin.

"I'm Lieutenant General Nebel of the Imperial Army, Dr. Melvin, your video communication is very effective, I hope you can supply this equipment to the military, there is definitely no need to worry about the military expenses required for procurement, this kind of facility is of great effect on the military, especially in the current war period, can it be installed on a moving warship?"

"This, I don't know, but I guess it should be fine, as long as it's still in the coverage of communication satellites, after all, now you and I are in contact with each other, all of them are transited through communication satellites, with a slight delay, but within an acceptable range."

Ten seconds later, Melvin's reply came, and these ten seconds were the delay time mentioned by Melvin, after all, it would definitely take some time for the two sides to transmit their respective communication information to the satellites in the sky and then send it down.

"I'll make contact with the command, I'm sure the command will be interested in this, thank you Dr. Melvin for your research, it's a blessing for the imperial capital to have such an outstanding scientist as you."

Nibel gave a military salute to Melvin, which was very solemn, and the fact is that if the image projection device is really preliminarily mass-produced, it will be of great help to the imperial army.

"Well, I'll do the initial mass production later, or Madame Merry will definitely pick my skin, hey, I still have a lot of work to do here, and I still have Carey's commission to do, oh my God, I won't want to be lazy for the next few months."

Melvin complained a few words, but still agreed to Nibel's request, after all, Melvin has a clear distinction between the most important in this kind of matter, and naturally there is no reason to stay out of the matter.

"See you later, Melvin."

Wang Yan stood aside and beckoned to Melvin, since the video communication has been successful, then you can contact at any time, of course, Wang Yan did not forget to ask Melvin to find a way to install the video communication on the communicator.

If Melvin can succeed, it means that the mobile phone will really appear in the celestial society, as an earthling, Wang Yan is clear about the role of the mobile phone, if Melvin can study it thoroughly, then the other party will inevitably obtain unimaginable wealth. 11
