Fang Shi originally thought that he would be able to have a peaceful and warm New Year, who would have thought that the strict Qingcheng Mountain, which was surrounded by the Security Bureau and the military, still had an accident, no, it was not Qingcheng Mountain that had an accident, but something happened in the real yàn room of Liuxian Cave.

Strictly speaking, it shouldn't be an accident, but something has been discovered, but these things are quite bad.

This matter also has something to do with Chen Bixin, Chen Bixin has nothing to do these days, so he will go to the real yàn room of Liuxian Cave to see if Academician Yuan and they have any breakthroughs, and see if there is any progress in the real yàn of the elixir, is the purpose not for him to be able to become a warlock.

On this day, he was helping Su Weimin to carry out the modification of the electromagnetic wave room, Su Weimin newly developed a more precise magnetic field sensor, reinstalled a new shielding box, redesigned the new transmission line, replaced the original metal cables with optical brazing, as much as possible to reduce electromagnetic interference, the back-end conversion interface, modules and processing programs have been changed, don't look at the shell is still the original appearance, but the inside is completely different.

Su Weimin proudly boasted to Chen Bixin and showed off, Chen Bixin was of course in awe, so he asked to demonstrate the ability of the new equipment, and Su Weimin was of course happy to do it.

So, the electromagnetic detector was turned on again, and soon the number of the sensor appeared on the computer screen, and because of the previous test number jù, the computer quickly distinguished and eliminated the known signal, and the signal began to become clear.

"The environmental noise is removed, and the known electromagnetic signals are removed, and the ultimate goal is to get a clean environment that is completely free of electromagnetic waves in the virtual environment of the computer. Hey? What is this? ”

Chen Bixin didn't understand. But he could also see that there seemed to be a signal on the computer that was stubbornly shaking on the screen.

"This one is very regular. It was sent by an artificial device, right? ”

Su Weimin nodded: "This is not a signal from your mobile phone, right?" The frequency is not right. ”

"My phone was left outside according to the regulations, and it was checked when I came in, and there was no electromagnetic signal on my body."

"But that's weird, where did this signal come from? Looks like it's still strong. ”

"Can't you detect the source of the signal?"

Su Weimin rolled his eyes: "Is this thing for that?" ”

"Who knows, I'll ask in passing, if it doesn't work, forget it, it's a background signal."

"That's not right! Wrong! All electromagnetic signals must be managed, and the signal zài is not included in the directory of signals sent by the Security Service. Hey, it's gone."

"No, you said it wouldn't be those, would you?"

Su Weimin frowned: "It's really possible, no, I have to inform Minister Xu about this matter, and let them find out what this signal is about, fortunately, I have a record here." ”

Xu Liquan was soon notified and rushed over, accompanied by a telecommunications expert from the Security Bureau.

Xu Liquan did not introduce them to each other, but directly asked Su Weimin: "Dr. Su, how did you find this signal?" ”

Su Weimin explained that he wanted to get a completely clean electromagnetic environment. After filtering out all the background signals, I found this guy mixed in the background signals and found out.

"This signal should be sandwiched between the high-frequency sources you gave me. The number of the signal source is G906, the baseband of this signal is the same frequency as G906 but the phase has a 40-degree error, my filtering algorithm just calculates according to the frequency and phase, and the result is filtered out"

Xu Liquan glanced at the telecommunications expert with a dark face, and asked in a deep voice: "If I remember correctly, this G906 should be the military's encrypted satellite channel, right?" ”

"Yes, but the frequency hopping point of this channel is strictly encrypted, except for what we know, only Dr. Su knows that this signal with some difference in phase wants to be mixed in this signal and send a signal to the near-Earth satellite."

"Are you sure this isn't our signal?"

"Absolutely not, I know our signal, this frequency point is never possible unless it is a new signal added by the military."

"You immediately try to find a way to determine the location of the signal source, and I will immediately confirm this matter with the military."

"Yes, but the signal could be sudden."

Su Weimin interjected: "Yes, it was only a few seconds just now, and then it disappeared." ”

Xu Liquan's brows furrowed: "Don't spread this matter anymore, Ashin, you tell Master Fang." ”

"Okay, I got it."

Xu Liquan quickly took a backup record and took people away, and at the same time issued a gag order, fortunately, only Su Weimin and Chen Bixin knew about it.

Xu Liquan hopes to quietly find out this person when the other party is not aware, and then catch it to see the situation and then decide, he doesn't think that this person is okay to travel with a satellite phone, although there are really a lot of tourists in Qingcheng Mountain now, but there is a blockade by the military and the Security Bureau, and now the back mountain is closed in the name of construction, and this direction has completely eliminated the arrival of tourists.

On the one hand, Xu Liquan has to investigate the personnel within the Security Bureau and the military, and on the other hand, the researchers are also the key suspects, and there are those people on Qingcheng Mountain, so he must first talk to Fang Shi.

That night, Xu Liquan and Lu Zhiyi found Fang Shi together, I heard that it was to catch spies, Xia Yuyao was not interested at all, she would rather study those real yàn numbers that have a lot every day, Xia Yuxin was quite interested, but Chen Bixin's cultivation was about to begin, and she still had to look at her Gathering God Array.

In the end, in the Fangshi room, only Xu Liquan, Lu Zhiyi and Chen Haiying, who was called by Lu Zhiyi, were left.

"Ashin has already told me about this, except for the head of the family, only the Xia family sisters know, you have confirmed that someone has infiltrated it?"

Xu Liquan glanced at Lu Zhiyi and said, "Yes." ”

Fang Shi pursed his lips: "Then have you made any progress?" ”

"Not yet, but we suspect the other party's identity is a warlock."

Fang Shi nodded, he understood the basis of Xu Liquan's guess. If the person is not a warlock. Then it is easy for the warlock to see through the true face. This is Qingcheng Mountain, and there is no shortage of powerful warlocks. And the only one who can deceive the warlock is the warlock, so it is understandable that Xu Liquan narrowed the scope of suspicion to the category of the warlock.

"Well, it's very likely."

Xu Liquan saw that Fang Shi agreed with his thoughts, and secretly breathed a sigh of relief: "Of course, we will also investigate ordinary people to prevent them from fishing in troubled waters." As for the warlocks. If you want to avoid startling the snake, it is a bit difficult to investigate. ”

"Well, you're talking about the people on Qingcheng Mountain, right?"

Xu Liquan smiled awkwardly and said: "Master Fang's eyes are like torches, that's what I mean, it's inconvenient for us to investigate the people on Qingcheng Mountain, can we trouble Master Fang to do this?" ”

Fang Shi smiled noncommittally, and Xu Liquan continued stubbornly: "I have discussed this matter with Captain Lu, we are responsible for the investigation of the mountain and the surrounding area, including the personnel on the construction site, and the mountain will be carried out by Captain Chen and Master Fang. ”

Fang Shi was silent for a moment. Lu Zhiyi and Xu Liquan unconsciously sweated on his forehead, and Fang Shi was now more and more powerful. Even these two powerful officials with not simple identities felt a lot of pressure in front of Fang Shi.

"You've arranged it, what else do I have to say, to be honest, I'm not really interested in this, we're making such a big fuss here, it's normal for someone to want to come and see what we're doing."

"It's normal, but they're not welcome to come and see it."

"I know, I'll screen the people on the mountain, you don't plan to alarm the other party, right?"

"Yes."

Fang Shi shook his head: "This is indeed a bit difficult. ”

Xu Liquan looked at Fang Shi in surprise: "Master Fang, is this tricky for you?" ”

"It's not me, I'm talking about you, you're tossing so much at the bottom of the mountain, will that person not be able to see it?"

Xu Liquan showed an embarrassed smile on his face, and said with a dry smile: "Master Fang, we are ready to start investigating at the bottom of the mountain after you have the results, and we are just listening at this stage." ”

Fang Shi smiled and glanced at Xu Liquan and Lu Zhiyi playfully: "It's very the style of the Security Bureau." ”

"I'm ashamed, but our methods are limited and our capabilities are insufficient."

Fang Shi waved his hand: "Okay, I know this matter, there are hundreds of people on Qingcheng Mountain, I need time." ”

"Is two days enough?"

"Is two days enough for me to see everybody?"

"Isn't this going for the New Year? Isn't Qingcheng Mountain going to have an annual party or something? ”

Xu Liquan said with a smile, Chen Haiying pursed his lips and smiled, this Xu Liquan is very bold with Fang Shi, but Lu Zhiyi is basically silent, it seems that Xu Liquan has a very good relationship with Fang Shi.

Fang Shi looked at Xu Liquan and smiled: "You have already thought about it, right, what other plans are there to talk about." ”

"No, it's really gone, I don't know what means Master Fang has, there are only so many things I can think of, if Master Fang finds out, don't alarm him, we also want to know who is behind him to control him, this kind of person dares to take a big risk to infiltrate, the background behind it must be not small."

"That's all?"

"Yes, Captain Lu, do you have any questions?"

Lu Zhiyi hurriedly shook his hand: "No, Captain Chen, please cooperate with Master Fang." ”

"Haiying is my classmate, I don't need you to order her, in fact, she can't help with this, well, it's okay to be a messenger."

Chen Haiying glanced at Fang Shi bitterly, he really looked down on people! I thought that I could show my ability in front of Fang Shi this time, not to mention impressing him, at least let him pay more attention to himself. It's a pity that Fang Shi's words are basically the truth, and Chen Haiying has no basis for refutation, she intuitively feels that Fang Shi may find Xia Yuxin's help in this matter, and she can really only be a messenger of news, if she is not worried about the leakage of mobile phone signals, she may not have anything to do with herself.
