Secretary Qi went to send the message, and the director looked at the message from Jiang Tengkong again.
It feels really good to have one of your own within the enemy. You can know what they are doing at any time, unlike before, where you were blind and could only defend passively.
The importance of roses has been reflected.
At the Hangzhou Police Academy, Deputy Director Yu received the secret telegram from the Chief. After seeing the contents of the telegram, he did not dare to neglect and immediately asked Zuo Xuan to call Chu Lingyun.
Chu Lingyun is in class. Today is the first class he teaches to the students here. The students in this batch have indeed heard Chu Lingyun’s name many times and are very curious about him.
Chu Lingyun is not a big shot in the department, he is just a team leader and belongs to the middle level, but he is the most popular person in the entire Military Intelligence Department.
There are no Internet celebrities 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 graduated from the military academy in just one year. Secondly, he has outstanding abilities. He can do things that others can do and can do things that others cannot.
The most important thing is that the results are dazzling.
After hearing about Chu Lingyun, many students who have never met him regard him as their idol. Now that Chu Lingyun comes to the school to teach them, these people are particularly excited.
"Look at this emergency contact signal, do you find any problems?"
Chu Lingyun wrote an address in Hangzhou on the blackboard. This was his real experience in the Wuhan investigation team, but the address was changed.
No one has ever talked about this case, so Chu Lingyun brought it up as the content of the first class.
A student immediately raised his hand, and Chu Lingyun asked him to stand up and answer: "The recipient of the letter is definitely not a spy. If so, it would be too easy to be exposed."
The students' reaction was good. At least they didn't act foolishly and said that this family was a spy.
Enemies are not fools. If you treat them as fools, you will definitely suffer in the end.
"Go on." Chu Lingyun encouraged.
After being confirmed, the student was very happy and continued: "I am thinking of two possibilities. One is that this family is related to the Japanese spy, and the spy will be notified after receiving the urgent contact letter. The other is that the postman is the Japanese spy.
As long as you see this letter, you will know that your downline is urgently making an appointment with you."
"Is there more?" Chu Lingyun asked again.
The student was stunned and immediately replied: "No, I just thought of these two points."
"Sit down."
Chu Lingyun smiled slightly. Today he was wearing a military uniform and the rank of major. He looked very energetic.
In order to keep it secret, he even put on some makeup to change his appearance.
This is not a precedent. People who have been lurking before came to give lectures. Some even wore masks to prevent others from knowing their true appearance.
It is very dangerous to lurk. No one can guarantee that all students will not be arrested and rebel in the future. If any students rebel, it will be a great threat to them.
"Does anyone have anything to add?"
Chu Lingyun asked again, the student just now thought that the postman was actually quite good.
Everyone has their own limitations. Not everyone can think of timeliness at the first time. Human thinking says that they will focus on the most important information first, and side details are often ignored.
In later generations, there are not a few people who look for their mobile phones with their mobile phones. They only think about where they put their mobile phones just now and ignore what they have in their hands.
"I have something to add." One person raised his hand again, and Chu Lingyun asked him to stand up and answer.
"Since it is a joint signal, then everyone who comes into contact with this letter may be a spy, including not only the head of the household and the postman, but also the person who picks up the letter, people at the post office, etc. I think the focus of the investigation should be all those who have access to the letter.
People who get letters."
As soon as he finished speaking, the first student who answered showed his annoyance. This student was right. Everyone who comes into contact with the letter may be a spy in disguise.
What he just thought was too one-sided.
"That's right."
Chu Lingyun smiled. The quality of this batch of students is not low. It is close to the truth to think of this.
The second student who answered was astonished. He thought his answer must be accurate, but he didn't expect that the instructor did not confirm it.
After sitting down, he was still a little reluctant and looked at the others.
The students' thinking is currently limited to signals, and no one thinks about timeliness.
But thinking of these things will already help solve the case, but it will require more manpower and material resources.
Seeing that no one raised their hands, Chu Lingyun said slowly: "This letter is an emergency contact signal. Everyone who has access to the letter is suspected, but one thing is the time when they access the letter."
As soon as Chu Lingyun finished speaking, several people looked surprised.
The instructor is right. Since it is an emergency contact, the signal must be seen within the specified time, otherwise it will lose its meaning.
"The emergency contact time is noon the next day, so the head of household and the postman can be eliminated directly."
Chu Lingyun continued, and the student who answered first lowered his head unnaturally. The two suspects he guessed were actually the least suspicious.
Under Chu Lingyun's reminder, almost all students thought about the time it would take to send a 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. As for the postman, it is possible to see the letter, but at least until the morning of the next day, or even later.
As long as it is possible to access the letter outside of time, he can rule it out. Intelligence work is very rigorous and does not allow such obvious loopholes.
"This is a real case. The most critical thing in this case is timeliness. After investigation, we found that there are two ways to send mail: business points and mailboxes, but only letters from the mailbox will be returned to the post office on the same day. So we are inside the post office
A detailed investigation was launched and the suspect was quickly identified as a sorter."
After explaining it clearly, all students understood that sorters are indeed the easiest and earliest people to come into contact with letters.
However, the first person to see the signal was the postman who went to the mailbox to receive the letter. However, there were too many mailboxes and more than one person was receiving the letter. If the mailbox was not fixed, there was no guarantee that the spy would definitely see the letter.
"Instructor, is the sorter a 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 sorters must be spies, so that after seeing the signal, they can meet their subordinates, but the instructor said that was not the case.
"The spy bribed a person in the post office and gave him money every month to keep an eye on these signals. The person in the post office also bribed the sorter. After the sorter sees the letter, he will notify the post office as soon as possible.
The person in the post office will go to the designated place and draw the signal. The spy can know that the downline has asked him to meet and who it is without having any contact with the person in the post office."
Chu Lingyun said slowly, and the students suddenly let out a slight cry.
There are so many spies arranged one after another, and the sorters do not know the existence of the spies, and even the people bribed by the post office cannot see the spies themselves.
In this case, security can indeed be improved.
"Japanese spies are so cunning."
A student sighed and said that just a signal for an emergency appointment is so complicated. We must not take such an enemy lightly.
From the moment they entered the school, they understood that their biggest enemy is the Japanese. They have always regarded the Japanese as their imaginary enemy.
But what the instructor taught before was all about formal information science, such as analyzing intelligence, obtaining intelligence, tracking and anti-tracking, etc. Even if there were cases, they were dry or outdated, and they were not as exciting as what Instructor Chu taught. p>
This is real practice, and just listening to this makes them feel that they have benefited a lot.
"Instructor, have you finally found this spy?" A student couldn't help but ask.
"I must have found it, otherwise the instructor would have said it." A student answered, and many people laughed out loud.
"Found it." Chu Lingyun smiled and nodded, and then sighed: "Although I found it, the enemy is too cunning. I released his subordinate to meet him, but the spy discovered the abnormality, and the subordinate was
He was beaten to death 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 Dujuan team was eliminated by him, which made up for this regret as much as possible.
"This can also make him commit suicide." The students were stunned.
In their opinion, their instructors did a very good job. It was not easy to identify so many people and find spies, but they did not expect that they did not have full success.
When a spy dies, his merits may even turn into faults.
As for such a case, the instructor actually mentioned it directly in the first class, which made many students admire Chu Lingyun even more.
It is even rarer to find an instructor who can talk about his own mistakes.
"Spies are far more difficult to deal with than we thought, so after you graduate, no matter where you fight, you must not underestimate our enemies. You must be fully prepared to deal with them."
Chu Lingyun said slowly, he had thought carefully about what to talk about first during the lecture.
This case is very educational, so he made it the first thing he talked about.
"Team Leader Chu."
Zuo Xuan suddenly appeared at the door of the classroom and shouted to Chu Lingyun.
"Instructor Zuo is here." Chu Lingyun glanced at him and strode to the door.
He is in class. Zuo Xuan must have something important to come here at this time, otherwise he would not disturb his class.
The first thing Chu Lingyun thought about was whether something would happen to the headquarters. He shouldn't have just left, and Ni Loach and Chu Yuan would have caused trouble.
"Follow me, Deputy Director Yu wants to see you."
Zuo Xuan whispered that the message was top secret. Deputy Director Yu did not tell Zuo Xuan the content of the message. This was the Virgo’s special arrangement in the message.
Only Deputy Director Yu and Chu Lingyun know this news, no one else is allowed to tell it.
Protecting your own insiders is also very important.
"Lingyun, sit down." After Zuo Xuan left, Deputy Director Yu pulled Chu Lingyun and sat down on the sofa.
Chu Lingyun took the initiative and asked: "Deputy Director Yu, did something happen at the headquarters?"
"It's something."
Deputy Director Yu nodded and handed the top-secret message from the Director to Chu Lingyun to read.
After Chu Lingyun carefully read the contents of the telegram, Deputy Director Yu picked up the telegram and burned it in front of Chu Lingyun.
"The Japanese can only do so much, but since they have noticed you, they must be careful in the future. He Nian has sent people to protect you. You stay in the school these days and don't go anywhere."
After burning the message, Deputy Director Yu slowly said that Chu Lingyun was being targeted by the Japanese. According to the Japanese's temperament, there will be many ways to deal with him.
And I won’t give up until I achieve my goal.
"I understand, thank you, Deputy Director Yu."
It's not that Loach and Chu Yuan have anything to do with each other. Chu Lingyun is relieved. As for the Japanese dealing with him, he has already expected it.
He has captured so many spies, and the Japanese hate him to the core, even if they don’t do it in such a shameful way, are they still Japanese?
"I will strengthen the security in the school, and your family members should also pay attention."
"I have made arrangements for my family, Deputy Director Yu. If there is nothing else, I will go back to class."
Chu Lingyun said goodbye. Fortunately, he had made preparations in advance. It was not easy for the Japanese to find out where his family had gone. Only Smith knew the exact whereabouts of his family.
And Smith has already returned to the United States, and I don’t know what he is doing.
At the beginning, he had told his parents not to tell outsiders about the new school, nor to their colleagues. The new school had not yet been successfully established, and if others knew about it, it would only attract ridicule from others. p>
My parents are face-saving people and will never show off to anyone before they have achieved results.
"Go ahead."
Deputy Director Yu smiled and said that being valued by the Japanese and even wanted to assassinate him proved that Chu Lingyun did a good job and really hurt the Japanese.
Being so valued by the enemy these days is also an affirmation of one's own achievements.
Although the first class was interrupted, Chu Lingyun still talked a lot after returning, including the case of Yang Jian.
Japanese spies are cunning and will arrange substitutes. When you encounter a lurking spy in the future, you must be cautious and check more.
"Team leader, here it is."
At noon, Shen Hanwen helped Chu Lingyun prepare meals. The food at Hangzhou Police School was good.
Shen Hanwen brought a few sesame seed cakes and a pot of meat, and the two of them sat facing each other and ate.
When Chu Lingyun was in class, Shen Hanwen listened to the class with the others. He also went to listen when Chu Lingyun was not giving lectures. Shen Hanwen had not received systematic training, so this time it was just right to help him recharge.
"The Japanese pretend to be poor, but in fact they cannot endure so much suffering. In order to feed himself, Silly Er actually asked people to pretend to be his relatives, pay the sesame cake shop in advance, and give him food as long as he goes there."
Shen Hanwen was biting into sesame seed cakes and eating fat meat. He suddenly remembered the Japanese spy Silly Er in the previous case and couldn't help but say.
Not only Sha Er is like this, Liu Wu is also the same.
Occasionally, Liu Wu would secretly get some delicious food for toothpaste. Only their team leader Yang Guang really only eats ordinary food and has never made any mistakes in this regard.
"They are also human beings, and as human beings they will have weaknesses. Who can endure real suffering?"
Chu Lingyun smiled slightly, but as he spoke, he remembered the most difficult period of the Red Party.
It was really bitter. All the tree roots and turf were eaten, and there was no food to eat. Even the leather belt could be eaten.
In terms of perseverance, no one can match these great predecessors.
