It was late at night, and the Tiger Roaring Ridge base also fell silent.

The Tiger Roaring Ridge base implements completely militarized management, and it is not allowed to move around casually at night, and at half past ten in the evening, it enters the light control time, and the soldiers' dormitories turn off the lights and go to bed on time.

Of course, special departments such as the headquarters and the monitoring department are not within this scope, and these places are often lit up 24 hours a day, and personnel can be seen coming in and out.

The monitoring department is divided into six departments, including a daily control room responsible for daily monitoring, a data room responsible for data control, and an anti-monitoring room dedicated to monitoring and anti-monitoring.

Since the beginning of the establishment of the base in Huxiao Mountain, the Huya Special Operations Brigade has set up an anti-listening room, which is mainly responsible for monitoring the surroundings of the base and preventing the enemy's spies from using radio to contact. Especially after the establishment of the laboratory, preventing the leakage of classified information has become a top priority.

Because a military factory has provided a large amount of modern monitoring equipment, the anti-surveillance room in Tiger Roaring Ridge is very advanced, and the information transmitted by the latest model of radio equipped by the Japanese army can not only intercept it, but also carry out simulated frequencies to send false information in a real way.

To put it simply, the equipment in the anti-surveillance room can send false information on the same frequency as the enemy's radio station, and the enemy's radio station can also receive the false information sent to them and think that it is sent by their own people.

As for code breaking, even if there is no code book, those multi-functional cipher code breaking machines can decipher any kind of code in this era.

Technology that has been leading for nearly 100 years is definitely an insurmountable chasm.

"Section chief, this signal has appeared for the eleventh time." Putting a document in front of Li Hongtao, the clerk quickly returned to his position and continued to work with his head down.

Li Hongbo is about 27 or 8 years old this year, but he has been a veteran of this industry for 10 years and has a lot of experience.

With a pair of sword eyebrows, bright eyes, and not too thick beard stubble, Li Hongtao is very handsome, but maybe he has been in this industry for a long time, he talks less, and often frowns most of the time.

Opening the information, Li Hongtao carefully flipped through the relevant records, and at the same time analyzed it in his heart.

The signal of this radio station was only recently discovered, but it was in frequent contact with the outside world during the week, and so far it has been contacted no less than 11 times, and the frequency is different each time.

In addition, this signal is very peculiar, and every time it moves, it seems to be constantly moving, which makes it difficult to determine its position.

Of course, this is also difficult for Li Hongtao and them, three days ago, they had already deciphered the characteristics of the other party's password, as well as the change of the frequency of sending, as for the scope of activities, they have also locked the approximate area.

Originally, at this point, the net could already be closed, but he received an order from Yan Beifeng, asking them to closely monitor this radio station, but don't take it lightly, everything is waiting for the orders from above.

Li Hongtao was very strange, and he didn't know what the political commissar was thinking about, but he could only stand by and send people to pay attention to that frequency 24 hours a day.

As a result, just now, this radio station was active again.

Although the new frequency has been replaced, this frequency has long been known by Li Hongtao and them through decipherment, and they laid a net in advance and waited for the prey to come to the door.

"The equipment is confirmed, the list is as follows: AK47 submachine gun, imitation Mosingan sniper rifle, wheeled armored personnel carrier, ......, whether to enable the first intelligence point to transmit detailed data, please indicate?" Li Hongtao read this paragraph in a low voice, and then stood up with a sigh of relief.

The section staff next to him was a little confused by Li Hongtao's movements, their section chief has always been calm, even if the fire burned his eyebrows, he could be calm and calm, and his face did not change, but he didn't expect such a big reaction this time.

Li Hongtao said in a deep voice, "Order Surveillance No. 1 and Surveillance No. 2 to make every effort to track the location of this radio station, and be sure to find out the area where he is located." ”

Seeing that he was so nervous, the staff knew that this time the matter must be more serious, so no one dared to delay, and immediately took their places and began to manipulate the instruments to track the location of the radio signal.

Li Hongtao's face was very serious, he stood behind the soldier who was manipulating the instrument, staring closely at the data that kept flashing on the screen, not daring to be careless and lax.

The intelligence this time is really amazing, and the first batch of weapons and equipment data just determined by the laboratory has been leaked, which is a big deal.

If the devils are allowed to get the detailed data parameters of these weapons, then they can make the same weapons, and then it will be absolutely very bad news for all the anti-Japanese forces.

Thinking of this, Li Hongtao couldn't sit still, and he immediately dialed Yan Beifeng.

It's so late, Yan Beifeng hasn't rested yet, and he is working overtime in the headquarters, seeing that it was Li Hongtao calling, he couldn't help but smile and said to Luo Xiao beside him, "Look, it's a call from the anti-monitoring room, Li Hongtao and they must have made a major discovery." ”

Luo Xiao nodded, and then said, "Well, I think the fish is starting to bite the hook." ”

"Then let's go and have a look." Yan Beifeng stood up, grabbed his military coat, and then walked out with Luo Xiao.

In the anti-monitoring room, Li Hongtao sat in front of the instrument, personally operated and tracked the radio signal, and drew a line on the map with a pen in his right hand, which seemed to be the trajectory of the other station's movement.

The line jumped in the forest of Tiger Roaring Mountain, the direction flickered left and right, and it seemed that there was no pattern to follow at all, and it was really difficult to determine its location.

Li Hongtao's expression was solemn, and it seemed that he had concentrated all his energy, and although he didn't look at his eyes, the pen in his hand accurately drew a trajectory of movement.

"Area Nine, the area is about three square kilometers. Mobile Express 1041PSTC. As Li Hongtao reported the data one by one, the other tracking staff also adjusted the instruments to ensure the most accurate tracking of the radio signal.

The door of the house was pushed open, Luo Xiao and Yan Beifeng walked in from outside, and when they saw Li Hongtao busy, they walked to Li Hongtao's side and quietly watched him busy.

Li Hongtao's mind was highly concentrated, and while he was staring at the constantly beating instrument in front of him, his brain seemed to be in the field, constantly moving.

The terrain of Tiger Roaring Ridge is almost familiar to him now, and he can restore the terrain and landform of any place when he closes his eyes, so he can track the opponent's movement in a timely and accurate manner.

After this tracking, Li Hongtao found that this latent spy was moving very fast, and he was able to keep up, and he almost lost it several times.
