"…ah..." Wei Daming also sighed. He reviewed the plan. Naturally, he knew that they had done their best, but he couldn't help but feel a little lucky.
"...What's going on? What's wrong?" Looking at the things being packed up, Wei Daming frowned and thought.
Seeing this, Zheng Junshan did not disturb him. He quietly approached Yang Haicheng and asked in a low voice: "Is it possible that the frequency band they used to send a message to be outside your listening range?"
"...It's unlikely..." Yang Haicheng shook his head slightly when he heard this, and said, "We took a lot of effort to get those listening equipment from foreigners at a high cost. The radio communication frequency band, whether it is civilian or military or other
, We've all covered."
Speaking of this, Yang Haicheng lowered his voice and said, "In other times, it may not be possible to take into account all of the manpower, but before and after this operation, we mobilized everyone to effectively listen to the communication frequency bands.
Even the frequency bands that are not suitable for wireless communications have reception equipment to listen to. Although only the interns are responsible, there are basically no other purpose of the equipment to broadcast and shoot interference, and every move can be easily
Discovered.”
Yang Haicheng told Zheng Junshan about the details of the work. Although he dispelled his suspicion, he also felt that it was a bit inappropriate.
"Are these situations involved in confidentiality?" Zheng Junshan asked in a low voice. Although the two sides had intersections, it was not too much. Moreover, this was a official business and had strict confidentiality requirements.
"It's true that it's a secret!" Yang Haicheng nodded and explained softly: "But these can still be told to you. As long as you don't leak it, you'll get a lot of money this time. You should need to cooperate with you later and catch it.
After checking, some situations must be informed, so that both parties can cooperate more tacitly.”
Zheng Junshan nodded, put his heart in his stomach, and asked in a low voice: "Haicheng, do you have any doubts about this?"
"Maybe they have a very short communication time, and they quickly completed the communication through the space we searched, which makes it possible that we cannot listen." Yang Haicheng frowned.
After hearing this, Zheng Junshan shook his head and said, "It's not like this time, Team Lin's side has been operating shortly after they have made abnormal movements and have begun to quietly destroy things.
In other words, this is likely to be a temporary emergency communication, and you have just adjusted your working methods. Without a prior communication plan, it is useless. They can basically not bypass your listening, right?
Another thing is that afterwards, they were orderly and almost deceived our response. No matter how they look at it, the communication between them doesn’t seem to be very short."
Understanding telecommunications work, Zheng Junshan can also say a few words based on the on-site situation, but after this, Yang Haicheng frowned even deeper.
"After saying this, even the possibility of their radio communication is eliminated. It would not be so coincidental that the contact time they agreed on was at that point.
And if they keep turning on the computer, we will definitely be able to detect it. No matter how you calculate it, it won’t make sense? How did they contact the outside world?”
As he was talking, Yang Haicheng rubbed his head and felt a headache about it. This matter was too strange and all kinds of possibilities. Unless you accept the chance of good luck and other possibilities, it would not make sense at all.
Seeing that the things were moved, Wei Daming also came to the two of them and found out. He didn't believe that he would have happened to be lucky.
"Director, do you want to look at other things? Let's discuss it later. Maybe there will be new clues!"
Both professionals have a headache like this. Zheng Junshan has no hope for the discussion and suggests that other matters be handled first.
The two nodded without saying much. They followed Zheng Junshan and came to the abrasive machine. Seeing the waste material ground into powder, the director and others felt both regretful and headache.
"There are some intact here." Seeing that the few people looked into the bucket, Zheng Junshan quickly pointed at the remaining parts on the workbench.
Wei Daming glanced at it and shook his head and said, "Those are the most common devices. The ones that are really important and useful are probably ruined, in this bucket."
After saying that, Wei Daming asked Luo Yiqiao, who was squeezed behind, to step forward and said, "Yiqiao, you are skillful and careful. Take out the waste in the bucket and pack it up, and take it layer by layer. They should be destroyed in order."
Luo Yiqiao nodded, pushed the glasses on his nose, checked them, and asked someone to help him find some plates, white paper, etc., and then began to carefully pick up things out.
After taking out a small plate, Wei Daming brought it, mainly by a team of senior engineers, senior engineers and even engineers in the communication equipment factory, he took it aside and carefully separated.
Looking at the careful and cautious look of everyone, Zheng Junshan knew that it would probably take a lot of time, so he simply took Wei Daming, Yang Haicheng and other several people to the basement where these equipment were built.
After a closer look, the basement has been in the past few years, but it has been renovated and increased support recently, and even installed ventilation fans. The ventilation ports were disguised as chimneys, which took a lot of effort.
This house was probably a bit particular about it before, and he should have lived in a wealthy and powerful person. He dug up this basement, but now it has been used by the Japanese.
However, the new basement renovation can also be seen from the naked eye. The old renovation has probably been in a few years, such as renovation, support, etc., while the chimney and exhaust fans are probably only newly installed for a few months.
In addition to those tables, there are also traces left by boxes on the innermost floor of the basement. After looking at it, it should be the weapon ammunition box they moved up to before.
Now, the remaining layout in the basement is very simple. In addition to the table, there is a padlock bookcase and a telephone. The phone is pulled off from it. It is probably used to inform the basement when there is an emergency.
Human.
Yang Haicheng turned around and took Zheng Junshan outside, and asked someone to find a ladder for him, went up to the roof, and checked the chimney that poked out of the roof.
The chimney is quite large, and the room below was replaced by these people to rest and build a stove for boiling water to keep warm as a cover. However, it was confirmed before that this was a double channel, one was to exhaust smoke and cover it, and the other was to
For ventilation.
However, the ventilation channel did not reach the roof, and the opening was hidden under the eaves and opened outside the house. It could burn fire and ventilate. Even boiling water and raging fire could make some movements and hide ventilation.
The sound of exhaust running.
After discovering the hidden mouth, Zheng Junshan did not ask someone to go upstairs to check the chimney mouth. However, Yang Haicheng thought there might be something wrong with it, so he found it.
The small chimney is covered with tiles on the top to prevent rain from pouring in, but this large window is not. It uses a herringbone roof similar to a house, and the inclined roof is made of wood and smoke outlet, which is close to one side.
Half flat hollow floral tiles.
When Yang Haicheng looked through the smoke exhaust hole, he discovered a trick. He lifted the carbonized wooden board on the surface. Sure enough, there was an antenna hidden inside, but it was stained with a lot of smoke.
"…Crack..." Yang Haicheng approached the probe to check the situation deeper, but his knee pressed against the chimney wall, but with a click, it seemed to have fallen into it.
He stood there quietly, not daring to move around. After a while, he dared to slowly move his knees away. Seeing that nothing happened, he looked carefully and found that the outer surface of the chimney was actually made of wood.
If you look carefully, the wooden board, or wood chip, is very thin, probably only half a millimeter. The outside surface seems to be made of brick surfaces made of pigments, glue, brick powder, etc., which are extremely realistic.
Yang Haicheng carefully broke off one piece and found that it was a small compartment inside, about two centimeters deep, and the antenna was also placed, which was much newer than the one inside the chimney.
After checking, it was like this on all sides. The height of the chimney poked out from the roof was half a head shorter than him. The herringbone and hollowed-out tiles were about ten centimeters above his belly button.
The antenna disguised in the chimney wall went down to his calf position, and the two were separated by a brick.
After a closer look, I didn't find any other situations. Yang Haicheng also quickly came down. The roof here was the tiled roof that was normally stacked in the south. It was different from the ones fixed with mud at the bottom of the north and it was easy to collapse.
"What did you find?" After coming down, without chatting with Zheng Junshan, Wei Daming came out of the basement. Seeing that his expression was much more relaxed, he asked.
"Director, I found the antenna and hid it on the chimney wall. I used this wooden piece to disguise it outside, and there was another antenna inside the chimney..."
Yang Haicheng pointed to the chimney and handed the wooden piece over. Wei Daming looked at it, then carefully observed the chimney before speaking.
"This antenna is really a lot! I have tried my best to pretend. I guess it was only after we had the ability to listen, right?"
"From the old and new perspectives, it should have been done in the past two months, but it's a bit strange. This place should have been enabled, but we have never heard of suspicious radio waves around this area.
If we haven't detected this time, we can still solve it with errors, coincidences and other unlikely reasons, but if it has been many times, it's unreasonable!"
After Yang Haicheng finished speaking, Zheng Junshan also added and said the message reported by Xiao Rui. This place has been activated several times, and the message that needs to be sent is not short, which proves the questions raised by Yang Haicheng.
Wei Daming had a great headache. After thinking about it, he simply threw the matter to Yang Haicheng and the others to investigate. He went to the abrasive machine to study the destroyed equipment.
The two looked at each other, smiled bitterly, and exchanged their eyes for a moment, but did not take action immediately. Instead, they followed Wei Daming to see if there were any new clues.
I don’t know whether it’s right or wrong, but there is indeed a situation. When Wei Daming arrived, several people were carrying a small plate with some yellow items on the plate, and they said quackly.
After hearing this, the two of them found that the plate was not copper material, but gold threads, gold pieces, etc., many of which had been ground and deformed, and they could not see their original appearance. Fortunately, their ductility was good and they were not.
Grind it thinly and you can barely see some of the original shape.
Abrasive machines are not those with blades, but are similar to stone mills. They just use machines to drive the rotation and slowly crush the materials in the trough. I don’t know if they are afraid of being too advanced to cause suspicion or what to say.
"Will gold be used on this device?" Zheng Junshan asked Yang Haicheng curiously.
Yang Haicheng nodded and explained: "Gold's conductivity and stability are better. It can be used in such a way that gold, silver and copper are arranged in such a way, and these characteristics are the same.
For example, some contacts on switches will use silver, but there is less silver in gold, including other important components, and rarely use gold. It is mainly because it is expensive and not worth it. There are almost no gold used on the market.
equipment."
Zheng Junshan nodded, thought for a while, and continued to ask: "Then are gold used in these equipment, is there any special function?"
Upon hearing this, Yang Haicheng explained: "The equipment is more refined and precise, and it needs to achieve higher and better performance in some aspects, and the devices are likely to need to be specially customized. Just this effort is enough to illustrate the problem."
After listening, Zheng Junshan thought about it for a while, but unfortunately he didn't think of anything. He looked at Yang Haicheng, and he actually met a piece of his eyes. Looking at his expression, he probably didn't think of anything.
They smiled awkwardly, and the two walked aside, smoked cigarettes, continued to think about the situation and wanted to find out the problem.
"Are you sure they really didn't contact each other by phone?" Yang Haicheng frowned and asked after a discussion, but after no results came true.
"I checked it, and I had secretly investigated the circuit situation in advance. I did not find any situations such as partial connections. After the attack, I also checked it. There were no suspicious wiring or other lines. I even cut the wires and looked at them.
No problem.”
After hearing this, Yang Haicheng waved his hand and said, "I didn't say this. I believe you have searched carefully. What I asked was that I was calling this phone call normally. I was sure that it was not passed before the action? There was no suspicious content.
, or it may be counted as long as you find the abnormal time."
"…This…" Yang Haicheng frowned. He really didn't know this. He thought everything was normal without reporting from the monitor.
"Sorry! I'll find out!" Zheng Junshan spoke and quickly called someone to ask them to find the person in charge of the monitoring to learn more about the situation.
Soon, the person was asked and found that there was indeed a situation, but they did not meet any of the two situations mentioned by Yang Haicheng. There was a phone call before the operation, but it was not released.
"Is this happening? Why don't you report it to me?" Zheng Junshan frowned slightly after hearing this, because at that time, not long before he discovered the abnormality.
The team members quickly explained that this situation was not uncommon. They also discovered this situation while listening before. Many phone calls that dialed in here would not be connected at all.
At that time, I suspected that there was a problem, but when I investigated the factory customers, I found the relevant situation. It turned out that the matches they produced were of excellent quality. The customers received by customers, or some other merchants around, would also inquire about the source and want to buy them.
Those customers are open places, so they naturally don’t want to have trouble with others because of this little thing. They usually give the factory’s contact information.
However, the factory does not serve as individual customers, and even only does some business of fixed merchants. At first, he answered, but then ignored it. He also tacitly chose to contact the customers at a fixed time to buy.
Anyway, it's just a small matter. If you don't contact me, you can basically fool the customer and their side with reasons such as insufficient production. If you really can't push it away, it will develop into a fixed customer supply.
After feedback, we discussed it and finally classified this situation as the main business that the factory wanted to continue to keep a low profile and facilitate the development of the company, that is, the espionage activities were not affected, so we adopted this method.
This can also explain the past. After all, the current shipment volume needs to be outsourced to people around them. If they increase it, they will need to recruit people. It is not convenient to recruit outsiders to carry out espionage activities, and it would be too wasteful to send people.
This is considered normal behavior and does not contain any special secrets. Therefore, the team members responsible for the listening team did not report the situation to Zheng Junshan, and he had just taken over and did not understand this.
