Secretary Qi went to send the report, and the seat looked at the message sent by Jiang Tengkong again.

It's a good feeling to have your own people inside the enemy, they can know what is going on at any time, unlike before, when they were blind and could only defend passively.

The importance of roses has been revealed.

At the Hangzhou Police School, Deputy Director Yu received a secret telegram from the seat, and after seeing the content of the message, he didn't dare to slack off, and immediately asked Zuoxuan to call Chu Lingyun.

Chu Lingyun is in class, today is the first class he has given to the students here, this batch of students has indeed heard of Chu Lingyun's name many times, and they are very curious about him.

Chu Lingyun is not a big man in the department, his level is only the team leader, and he belongs to the middle level, but he is the hottest person in the entire military intelligence department.

There is no Internet celebrity in this era, otherwise he would be the number one Internet celebrity in the Military Intelligence Department.

First of all, he is young, very young, he has only graduated from the military academy for a year, and secondly, he has outstanding ability, he can do what others can do, and he can do what others can't.

The most important point is that the results are dazzling.

After hearing about Chu Lingyun, many students who had not seen him yet, many regarded him as their idol, and now that Chu Lingyun came to the school to teach them, these people were very excited.

"Do you see any problems with this emergency contact signal?"

Chu Lingyun wrote an address in Hangzhou on the blackboard, which was his real experience in Wuhan's Chadujuan group, but the address was changed.

No one had ever talked about this eucalyptus, and Chu Lingyun took it out as the content of the first lesson.

A student immediately raised his hand, and Chu Lingyun asked him to stand up and answer: "The recipient is definitely not a Japanese spy, if so, it is too easy to be exposed." ”

The trainee's reaction was good, at least he didn't make a stupid mistake, saying that this family was a Japanese spy.

The enemy is not a fool, and if you treat them as fools, you will definitely suffer in the end.

"Go on." Chu Lingyun encouraged.

After being affirmed, the trainee was very happy and continued: "I think there are two possibilities, one is that this family is related to the Japanese spy, and after receiving the letter of emergency contact, the Japanese spy will be notified, and the other is that the postman is the Japanese spy, as long as he sees this letter, he knows that the downline is urgently meeting him." ”

"Anything else?" Chu Lingyun asked again.

The student was stunned, and immediately replied: "No, I thought of these two points." ”

"Sit down."

Chu Lingyun smiled slightly, today he was wearing a military uniform, wearing the rank of major, and he looked very energetic.

In order to keep it secret, he also deliberately put on some makeup for himself and changed his appearance.

This is not a precedent, and people who have been lurking before come to give lectures, and some even wear masks to prevent people from knowing what they really are.

Hiding is very dangerous, and no one can guarantee that all students will not be arrested and mutiny in the future, and if any students defect, it will be a great threat to them.

"Does anyone have anything to add?"

Chu Lingyun asked again, it was actually very good for the student just now to think that the postman was actually very good.

Everyone's has their own limitations, not everyone can think of timeliness at the first time, people's thinking will focus on the most important information first, and the side details are often ignored.

In later generations, there are not a few people who look for mobile phones with mobile phones, and he only thinks about where he put his mobile phone just now, ignoring what he has in his hand.

"I have something to add." One raised his hand again, and Chu Lingyun asked him to stand up and answer.

"Since it is a connector signal, then all the people who come into contact with this letter may be Japanese spies, including not only the head of the household and the postman, but also the person who takes the letter, the person at the post office, etc., I think the focus of the investigation should be all the people who can contact the letter."

As soon as he finished speaking, the first student to answer showed his chagrin, this student was right, all those who came into contact with the letter were likely to be disguised as Japanese spies.

What he just thought was too one-sided.

"That's a good point."

Chu Lingyun smiled, the quality of this batch of students is not low, and it is close to the truth to be able to think of this.

The second student who answered showed surprise, he thought that his answer must be accurate, but he didn't expect the instructor to give an affirmation.

After sitting down, he was still a little unwilling and looked at the others.

The students' thinking is currently limited to signals, and no one thinks about timeliness.

But being able to think of these has already helped to break the eucalyptus, but it requires more manpower and material resources.

Seeing that no one raised his hand again, Chu Lingyun said slowly: "This letter is an emergency contact signal, and all those who can access the letter are suspicious, but there is one point, the time they have been in contact with the letter. ”

As soon as Chu Lingyun finished speaking, several people were surprised.

The instructor is right, since it is an emergency contact, it is necessary to see this signal within the specified time, otherwise it will lose its meaning.

"The emergency contact time is noon the next day, so the head of the household and the postman can directly rule it out."

Chu Lingyun continued, the first student to answer lowered his head unnaturally, the two suspects he guessed were actually the least suspicious.

Under Chu Lingyun's reminder, basically all the students thought of the time it would take to send the letter.

Even in the same city, it is impossible for the head of the household to get the letter within the agreed time the next day, and as for the postman, it is possible to see the letter, but at least until the morning of the next day, or even later.

Whenever it was possible to have access to the letters outside of time, he could rule them out, and the intelligence work was very rigorous and did not allow for such obvious loopholes.

"This is a real example, the most important thing in this eucalyptus is timeliness, we have investigated, there are two ways to send mail, business and mailbox, but only the letter of the mailbox will be recycled to the post office on the same day. So we launched a detailed investigation inside the post office and quickly identified the suspect, who was a sorter. ”

After making it clear, all the trainees understood that the sorter was indeed the easiest and the first person to have access to letters.

However, the person who really saw the signal first was the postman who went to the mailbox to receive the letter, but there were too many mailboxes, and more than one person received the letter, and if it was not a fixed mailbox, there was no guarantee that the Japanese spy would definitely see the letter.

"Instructor, is the sorter a Japanese spy?"

A student couldn't help but ask, Chu Lingyun smiled and shook his head: "No." ”

No?

The students' eyes widened, in their opinion, the sorter must be a Japanese spy, so that after seeing the signal, they can meet with their downline, but the instructor said no.

"The Japanese spy bribed a man in the post office, gave him money every month, told him to keep an eye on these signals, and this guy in the post office bribed the sorter. After the sorter sees the letter, he will notify the person at the post office as soon as possible, and the person at the post office will go to the designated place to draw a signal, and the Japanese spy will not have any contact with the person at the post office, so he can know that there is a line to meet him, and he can also know who it is. ”

Chu Lingyun said slowly, and the students suddenly let out a slight cry.

There are so many arrangements for Japanese spies, layer after layer, and the sorters don't know about the existence of Japanese spies, and even the people who are bought by the post office can't see the Japanese spies themselves.

In this way, it is indeed possible to achieve a higher level of security.

"Japanese spies are really cunning."

One of the students sighed and said that just an urgent appointment signal is so complicated, and such an enemy must not be taken lightly.

From the moment they entered the school, they understood that their biggest enemy was the Japanese, and they had always regarded the Japanese as imaginary enemies.

But what the instructor talked about before was all formal intelligence, such as analyzing intelligence, obtaining intelligence, stalking and anti-tracking, etc., even if there were examples, they were dry or outdated, and they were not as wonderful as what Instructor Chu said.

This is the real real battle, and just listening to this one makes them feel that they have benefited a lot.

"Instructor, did you finally find this Japanese spy?" One of the trainees couldn't help but ask.

"I must have found it, or the instructor would have said it." Some students answered, and many people laughed out loud.

"Found it." Chu Lingyun smiled and nodded, and then sighed again: "Although I found it, but the enemy is too cunning, I let his downline go out to meet him, and was discovered by the Japanese spy, the downline was killed by him on the spot, and the Japanese spy also committed suicide on the spot." ”

Du Juan's death is indeed Chu Lingyun's regret.

Fortunately, the entire Du Juan group was eliminated by him, and he made up for this regret as much as possible.

"It would also make him kill himself." The cadets froze.

In their opinion, their instructors have done a very good job, and it is not easy to find so many people and find Japanese spies, but they didn't expect that they didn't have all the work.

The Japanese spy is dead, and the merit may even become excessive.

And such a eucalyptus, the instructor actually took it directly, and it was the first class to talk about it, which made many students admire Chu Lingyun even more.

It is even more rare for such an instructor to be able to tell his mistakes.

"Japanese spies are far more difficult to deal with than we think, so after you graduate, no matter where you fight, you must not despise our enemies, and you must fight with twelve points of spirit to deal with them."

Chu Lingyun said slowly, what to talk about first when he gave a lecture, he thought it through.

This eucalyptus is very educational, so he used it as the first thing he talked about.

"Team Leader Chu."

Zuo Xuan suddenly appeared at the door of the classroom and shouted at Chu Lingyun.

"Instructor Zuo is here." Chu Lingyun glanced at him and strode to the door.

He is in class, and there must be something important for Zuo Xuan to come over at this time, otherwise he will not come to disturb his class.

Chu Lingyun's first thought was whether something would happen to the headquarters, and he shouldn't have just left, so Loach and Chu Yuan stabbed the basket.

"Follow me, Deputy Director Yu wants to see you."

Zuo Xuan whispered, the message is top secret, Deputy Director Yu did not tell the content of the telegram, this is a special arrangement in the message.

This news can only be known to Deputy Director Yu and Chu Lingyun, and no one else is allowed to tell it.

It is also very important to protect your inner line.

"Lingyun, sit." Walking left and turning, Deputy Director Yu pulled Chu Lingyun to sit down on the sofa.

Chu Lingyun took the initiative to ask, "Deputy Director Yu, is there something happening at the headquarters?" ”

"It's something."

Deputy Director Yu nodded, and handed the top-secret message sent by the seat to Chu Lingyun to see.

After Chu Lingyun carefully read the content of the message, Deputy Director Yu picked up the message again and burned it in front of Chu Lingyun.

"That's all the Japanese have to offer, but since they have noticed you, you must be careful in the future, the Chinese New Year has sent someone to protect you, you stay in the school these days, don't go anywhere."

After burning the telegram, Deputy Director Yu said slowly, Chu Lingyun was targeted by the Japanese, and according to the Japanese temperament, there will be many means to deal with him next.

And it is not the goal, and it will not give up.

"I understand, thank you Deputy Director Yu."

It wasn't for the loach and Chu Yuan's matter, Chu Lingyun was a lot more relieved, as for the Japanese to deal with him, it was already within his expectations.

He caught so many Japanese spies, and the Japanese hated him to the core, and they didn't need to see the surface in some way, are they still Japanese?

"I'm going to be on top of the school, and your family is going to be on the lookout."

"I've already arranged it for my family, Deputy Director Yu, I'll go back to class if I have nothing else to do."

Chu Lingyun offered to leave, fortunately he had made preparations in advance, it was not easy for the Japanese to find out where his family went, and only Smith knew the exact whereabouts of his family.

And Smith will have returned to the United States a long time ago, and I don't know what he is doing.

At the beginning, he told his parents not to tell outsiders about the new school, and not to tell their colleagues, because the new school has not been successfully run, and if it is known by others, if it is not done well, it will only attract ridicule from others.

Parents are face-loving people, and they will never show off to anyone until they make achievements.

"Go ahead."

Deputy Director Yu said with a smile, being valued by the Japanese and even assassinating him proves that Chu Lingyun is really doing a good job, and he really hurt the Japanese.

Being so valued by the enemy in these years is also an affirmation of one's own achievements.

Although the first class was interrupted, Chu Lingyun still talked a lot after he went back, and talked about the eucalyptus example of Yang Jianzi.

Japanese spies are cunning and will arrange stand-ins, and when you encounter lurking Japanese spies in the future, you must be cautious and check more.

"Team leader, give it."

At noon, Shen Hanwen helped Chu Lingyun cook, and the food at the Hangzhou Police School was good.

Shen Hanwen brought a few baked cakes and a pot of meat, and the two sat facing each other to eat.

When Chu Lingyun was in class, Shen Hanwen followed others to listen to the class, and he had to listen to it when Chu Lingyun was not lecturing, Shen Hanwen had not received systematic training, and this time he just helped him recharge.

"The Japanese pretend to be poor, but in fact they can't stand so much suffering, and for the sake of their own food, the fool actually asked people to pretend to be his relatives, pay for the baked cakes in advance, and give him something to eat as long as he goes."

Shen Hanwen bit the baked cake and ate the fatty meat, and suddenly remembered the Japanese spy stupid two in the eucalyptus before, and couldn't help but say.

Not only is this the case for Silly Er, but also for Liu Wu.

Occasionally, Liu Wu would secretly get some delicious food and fight tooth sacrifices, only their team leader, Yang Guang, usually only ate some ordinary food, and never made a mistake in this regard.

"They are also human beings, and if they are human beings, they will have weaknesses, and who can endure the real suffering."

Chu Lingyun smiled slightly, but when he spoke, he remembered the most difficult period of the Red Party.

It was really bitter, the roots and turf were all eaten, there was no food to eat, even the belts could be eaten.

When it comes to perseverance, no one can compare to these great predecessors.
