When Heliga, who was drinking tea outside, was shown up and taken back by Fei, he thought that he was going to experience an unforgettable attack in his life - after all, the two girls probably talked a lot about themselves, and he was mentally prepared to be judged.

However, Fei didn't seem to have any intention of mentioning this matter at all, just dragged him on, which made him very puzzled. However, when he heard Ling's explanation, he also understood why Fei brought him back in such a hurry.

Ling's so-called "magic" is to use a certain conductive inverter, combined with the special functions of "ARCUS", to achieve a certain goal that seems a little distant now.

"It's a signal conversion device...... It's what I used to play with myself when I was here before...... I didn't think it would be of any use, but I didn't expect Grandpa Yoguru to keep it for me. "What Ling is holding in her hand is a wonderful device like a spiral coil, but the filling inside is some special metal and slots for the conduction loop, but Helriga and Fei can't understand what it's for," the one next to him ...... It's a guided camera produced by the Urnu Society, which is something that is used in places like shopping malls. It was also when I was idle and bored before, and Grandpa Yoguru asked someone to bring me to pass the time to play. ”

"Will these two things be of any special use?" Heliga asked.

"yes...... To put it simply, I want to use this device to make something that can make video calls remotely. Ling nodded, "It seems that Helica's and Fei's companions also use similar power guides, right?" I just took a little look, and these two power guides seem to be in mass production in terms of internal core accessories, but with some targeted small-scale modifications, but it doesn't hurt - all in all, have you ever heard of the "conductive wave resonance phenomenon"? ”

“……”×2。

"Okay......" Ling helped his forehead - sure enough, after staying in the Chase Central Workshop for a long time, he suddenly came to two so-called laymen to explain the technology, and he still didn't change his mind. However, after all, the relationship between these two people and herself can be regarded as close, so she took the trouble to carefully explain the principle.

Looking at the change in Fei's expression, Helriga was sure she didn't understand it—but he understood it a little bit. To put it simply, when the technology of conductive communication began to slowly become popular, some researchers found that the propagation speed of conductive waves in the air is very fast, but the conductive waves generated in nature also have very similar frequencies. Conductive waves of similar frequencies will produce a phenomenon of resonance, resulting in mutual interference between the two segments of communication. In the earliest days, conductive communication was only applicable to the military or large-scale conductive experimental institutions, and there were almost no interference signals in nature, so it did not attract attention, but with the progress of technology, wireless communication began to enter the civilian sector, and there was such chaos for a period of time. In order to avoid this, the best way is to limit different communications in different bands, so that the frequency difference between the bands can live in peace and quiet, without causing any interference - in this regard, Dr. Russell proposed a series of new technical specifications and standards, stipulating more than a dozen bands of different frequencies for wireless guided communication for various purposes, such as civil public broadcasting, some commercial frequency bands exclusively purchased by large companies, and confidential military communications.

According to Ling's research results, the higher the frequency of the conductive wave, the more penetrating it will propagate and the more distant it will be...... However, the ultra-high-power high-frequency conductive wave generator has not yet been put into practical use and is still in the testing stage, mainly because of the high cost. But in the lab, Ling was already able to do something similar. ”

"I see...... So what you mean is that the "ARCUS" force guide can also be used for this purpose? Heliga nodded in understanding.

"Hmm...... I don't know exactly how this force guide is constructed, but after checking it out just now, I found out that it has a universal device built into it that can be used as a simple synergistic vibration amplification device. Its inherent emission capability is very weak, but it is artificially weakened, not innate—it is also very frequent, higher than all the bands commonly used in the simple communication protocols currently used on the continents, and even in nature, such high-frequency conductive waves are rarely generated. Speaking of her own profession, Ling can now be described as a dance of eyebrows, "So, if you use a guide wave of this frequency to communicate, even if it is in a wide range, there will be no interference - so that ultra-long-distance communication can be realized." ”

"I see. Wait......" Helriga seemed to think of something - who else would use the same power guide but his companions? "You don't want to ......"

By the way, since coming to Crossbell, perhaps because of Kia's power to resonate with the surrounding spiritual field, the arcus in the hands of Helliga and Fei seems to have temporarily lost the function of external communication, but occasionally can receive signals intermittently.

"Hmm...... If you take advantage of this, you should be able to get past the interference of the "field" around Crossbell now. Ling nodded, "How about it, do you want to try it?" ”

"If you can reach them, of course." Helliga nodded, "Just, how can we help you?" ”

"You and Sister Fei are just watching from the sidelines." Ling said proudly, "I have all the pre-experiments and the necessary equipment here, but I just need to connect the signals between the two "ARCUS". As for adaptation, it shouldn't be a big problem...... By the way, where should your classmates be at this time? ”

"Hmm...... If it were to be distributed, it would be in two large locations southwest and northwest of Crossbell. I don't know what their situation is on the other side of the Nolde Plateau......" Heliga thought to himself.

"Understood...... As long as you have an approximate orientation, you can do it. By the way, the Luray region in the northern part of the empire also seems to occasionally emit high-frequency signals, presumably the result of experiments at the famous university there. Ling said, "When the time comes, you'll have to avoid that side a little...... As long as it can be transmitted to the Nolde Plateau, it shouldn't be a big problem. ”

——————————————————————————————

"Elder Ivan, it's been almost two hours past the scheduled time...... Mr. Gunn, they haven't come back yet. The tall and burly man said to the old man beside him in a little anxious manner at this time, "Just to be safe...... Do you want to take someone over there to have a look? ”

"Really...... Nolde West Region...... Ever since the Empire's civil war began, our people must have been a little negligent about exploring over there. Although the tall man in front of him, Lagan Waozel, the father of Gaius Wozel, a Class VII student, was the current number one warrior of the tribe, few people knew that he had never defeated the unattractive old man in Nolde's cross-marksmanship until the age of the diminutive Elder Ivan in front of him. In addition, although Elder Ivan, who is old, is no longer directly involved in the affairs of the tribe, he can still use his wisdom and experience to give a lot of useful guidance to the young people of the tribe. For example, now, even though Ragon had proven himself to be a qualified tribal leader more than a decade earlier, he instinctively wanted to consult Elder Ivan on such a major matter.

"Hmm...... It is said that some magical beasts have appeared over there that cannot be described by common sense. According to the Imperials who fled here, they called that thing a "phantom beast"? "Ragon frowned, "They will suddenly appear in some places, wreak havoc, and then disappear after a while...... It's really strange to say. Mr. Gunn: They're not going to touch these things, are they? ”

"Possibly...... But relax. Didn't Mr. Gunn's granddaughter accompany him? And that little dot together. Elder Ivan said with a pleasant face, "Don't look at her usual appearance, but at critical moments, she is the kind of person who is very reliable. But your worries are not unreasonable...... Besides, even if it wasn't because of the encounter with the phantom beast, it was possible that the car broke down. It's not the first time that car has broken down...... Maybe they were delayed on the way to repair. ”

"That's just as well." After listening to Elder Ivan's analysis, Ragon softened his expression and said.

"Just to be on the safe side...... When Gaius returns from the northern part of the plateau, let him stop by and go west. Whatever the case may be, it's always right to have someone to pick up. The real concern now is the ...... of communications If this thing is working properly, we'll be able to get in touch with them anyway now. ”

"Yes......" Ragon followed the direction of Elder Ivan's gaze—inside the Elder's tent in the village of Nolde, it was a guiding device that looked to be some years old. It was a fixed-point communication device, and it was brought by the former president of the "RF Society" many years ago after he came here. The proud sons of the Nord Plateau also have the opportunity to enjoy the convenience brought by modern guide technology; Therefore, they also have a very natural closeness and trust for Mr. Gunn.

However, since sometime the other day, all communication equipment in the Nolde Plateau seems to have been completely disrupted - even Gaius's guide that could have been used by the two classmates he brought with him could not continue to communicate. In this case, it is easy to imagine how difficult it is to investigate the cause of this situation and continue to carefully maintain the stable life of the entire tribe in the face of the sudden loss of guiding communications.

However, despite such a special time, Mr. Gunn did not heed Ragann's advice and briefly left Nolde to take refuge in other autonomous regions—how could he leave Nolde at such a time when the people of Nolde treated him as if they were friends? Gunn not only directly and simply canceled the original travel plan - anyway, because of the war, most of the places could not be visited - but also took the initiative to live with the members of the tribe, and would try his best to help with any problems that usually arise, which made Elder Ivan and others very moved.

At the moment, the classic car, which often has problems, needs to deliver some supplies to another village in the west of Nolde, and exchange some resources that the other party still has surplus and has overstretched reserves here, and the herders need to live, and in order to avoid various problems caused by the downtime of the classic car on the road, Mr. Gunn also volunteered to go with him, but he didn't expect that this trip has been delayed for two hours and has not returned-how can this make them not anxious.

"Father, Elder Ivan, I'm back. There was nothing unusual on the northern side of the plateau, but—" Just as the two of them were anxious like ants on a hot pot, a faint but reliable voice sounded outside the tent—a man who was half a head shorter than Ragon but tall and burly appeared in front of them. His skin was as dark as Lagon's, he held a formidable looking crossspear in his hand, and his body was slightly sweaty from the movement that had just galloped back from his horse—his eyes were calm and resolute, and he seemed to be able to tolerate everything even though he was still so young.

He was Gaius Vozel, also a member of Tolz Class VII. As soon as Gaius entered the door, it was obvious that something was wrong with the atmosphere in the tent, so he stopped talking and looked at the two with puzzled eyes.

Gaius ...... You've come just in time. Ragan said to his eldest son in a calm and trusting tone, "Although I want to say that I have worked hard for you...... But something went wrong. I might have to work hard for you again. ”

"What's wrong? Could it be Mr. Gunn, they ......"

"Hmm. They should have been back two hours ago. Maybe I'm overthinking, but anyway, it's better for you to pick it up. Elder Ivan said, "Take a break, drink two cups of vanilla tea, take lunch and go—no problem?" ”

"Rest assured. Since that's the case, I might as well go now. Gaius nodded, not wanting to excuse himself, "In that case, father and elders, please take care, I-"

Before he could finish his sentence, he was interrupted by a piercing ringing sound from his waist. Gaius, who heard this voice, instinctively felt a little familiar, and immediately thought of something, and his pupils suddenly contracted.

This sound is a beep when a communication comes!

And Nolde, on the other hand, has been for almost a week...... There was no conductive communication.
