As it turned out, Lane and the others were right in their fears - the aristocratic coalition did still have a trail of hands. Shortly after they left the Surveillance Tower, the mechs who had left the garrison after an altercation with Valut returned to the base near the Surveillance Tower, bringing with them the Marquis of Rogner's exact words - if you were dissatisfied, go directly to him. This extraordinary attitude aroused Valut's interest, and he immediately expressed some admiration for His Excellency the Marquis, and did not further embarrass the soldiers, and then walked away with a cigarette in his mouth, which on the one hand made the soldiers of the mecha soldiers feel confused, and on the other hand, they had more respect for the Marquis of Rogner.

If they had attacked rashly, there would have been no doubt that they would have been hindered by the two executors, Bloblan and Valut, as well as the Black Rabbit and the soldiers. Despite the presence of Claire and Tovar, the two executors could be held back for a while, but that meant they had no room to do more. Once they fail to destroy the signal shield at the top of the tower, they will be held back until the reinforcements come from the Marquis of Rogner again, and the situation will be completely reversed. Students who have been on the radar of the Noble Alliance will also be arrested and lose the opportunity to follow up.

Moreover, they had no idea where the device was until they returned to the relocated tribe and recounted in detail to Ragon and Mr. Gunn in their lakeside hut.

"I see...... It seems that Lieutenant General Sykes should not be wrong in his judgment. Ever since the tower was destroyed, it has been repaired by regular army personnel, and I don't recall anyone associated with the Notia State Army during that time. Ragon said as he reflected on the people he had seen during that time.

"Hmm...... In the work of the Intelligence Bureau, it seems that it is also mentioned that the military department of the empire is fully responsible for this matter, and there is no aristocratic faction to interfere. Presumably, it was after the end of the war that the Marquis of Rogner forcibly took it. Miriam nodded - normally, when the people of Class VII and related people were discussing something, once the problem had been identified, Miriam would naturally tell a fact that the intelligence bureau had come to a similar conclusion, leaving everyone in Class VII speechless for a while. However, Miriam was able to prove the whole thing right very clearly, so they were not wrong in their guesses.

"Also, after we moved here, I did a little bit of research...... Judging by the equipment I have here, it should indeed be the problem with the surveillance tower. There was something in that tower that hindered the communication of directional conductive waves, making it impossible for conductive signals in the ordinary sense to propagate through space...... But their own equipment should have been commissioned. Gunn nodded, and then seemed to suddenly remember something, "By the way, Brother Ivan, I remember you just said that earlier this afternoon, you received a contact, it was Alyssa and their classmates?" ”

"What? And what's going on? Rien was shocked—Gaius hadn't told him.

"Ah...... Oh, yes. I was in such a hurry that I forgot about it. "According to Heliga, it seems that his friend helped to use a very high frequency guide signal, and then used the transmitting frequency of "ARCUS" as a synchronous ......"

"Amazing...... This kind of thinking and action. The other party must be a very powerful technician. I didn't expect Crossbell to hide such a talent...... You'll have to pay a little attention next time you go. Gunn exclaimed—as a senior technician, he knew how difficult it was to do so, "Come, boy, bring me your detractor—if it were to be located through the detractor, the center of "ARCUS" would still have the data from that time. I'll see if I can parse it. ”

"Hmm...... Please. Gaius handed the detractor to Gunn. After Gunn took the power guide, he took out the equipment he had stored in the warehouse, which even Alyssa couldn't name, and began to toss and tinker. When Alyssa saw her grandfather like this, she didn't say anything for the first time, but just sighed to her companion that she hadn't seen her grandfather like this for a long time.

"Hmm...... Parsing is complete. It's an extraordinary technique...... This is a very powerful force conversion device. Gunn said, and then he also popularized the communication bands of several conductive frequencies commonly used in the Semuria continent, "This frequency of conductive waves can travel in space for a long time, and maintain extremely high clarity when transmitting in a directional way...... However, it has not been used by any agency or organization as a communication. ”

"Why?" Riehn asks - according to Gunn, high-frequency conductive waves are not easily interfered with in the process of propagation, so their signal preservation is also the best, and the safety performance is higher when used for communication, but why is no one using it?

"Because the cost is too high...... To create such a stable signal source, a large amount of high-purity conductive energy is required for conversion. "Simply put, it's so expensive that the benefits it can bring are not worth mentioning in the face of such costs." Therefore, although a few years ago, an anonymous author wrote the relevant experimental data and gave a very clever design, but it was still very expensive", so that only the Luray University of Technology, Chase Central Workshop and other places did the relevant experiments, and then canceled it because there was no way to put this technology into the market. As Gunn spoke, the bits and pieces that had been sealed in the depths of his memory were gradually awakened, "However, it's a little strange to talk about this...... Although the author chose to publish anonymously, I can see that there are several anonymous papers that have been published by this person. As for why he posted it anonymously, I don't know about this. ”

"Hmm...... Leaving this aside, in short, although this kind of communication cannot be used on a large scale, in the current situation, it is something that cannot be covered by the signal shielding devices of the Nord Plateau...... In other words, communication can be done in this way, right. Alyssa asked.

"Yes...... Although the method is probably different from the other party's implementation, I can actually do the same thing here. Gunn smiled mysteriously and pointed to the machine behind him that he had adjusted, "However, it is theoretically possible that all of you need to synchronize the signals with your tactical power guides. ”
