Chapter 228 The First Lesson
Secretary Qi went to send the telegram, and Virgo looked at the telegram from Jiang Tengkong again.

It's a good feeling to have one of our own inside the enemy. They can know what they are doing at any time. Unlike before, they are blind and can only passively defend.

The importance of roses has been reflected.

At the Hangzhou Police Academy, Deputy Director Yu received a secret telegram from the chief officer. After seeing the content of the telegram, he didn't dare to neglect, and immediately asked Zuo Xuan to call Chu Lingyun.

Chu Lingyun is in class. Today is the first class he gives to the students here. The students in this group have indeed heard of Chu Lingyun's name many times and are very curious about him.

Chu Lingyun is not a big shot in the department, his rank is only the team leader, which belongs to the middle level, but he is the hottest 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 only one year ago. Secondly, he has outstanding abilities. He can do what others can do, and he can also do things that others cannot.

Most importantly, the results are brilliant.

After hearing about Chu Lingyun, many students who had never met him regarded him as their idol. Now that Chu Lingyun came to the school to teach them, these people were very excited.

"Look at this emergency contact signal, do you find any problems?"

Chu Lingyun wrote down an address in Hangzhou on the blackboard. This is his real experience in the Cha Dujuan team in Wuhan, but the address has been 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 replied, "The recipient is definitely not a spy. If so, it would be too easy to expose."

The reaction of the students was good, at least they were not stupid, saying that this family was a spy.

Enemies are not fools, if you treat them like fools, then you must be the one who suffers in the end.

"Go ahead." Chu Lingyun encouraged.

After being affirmed, the student was very happy, and continued: "I think there are two possibilities, one is that this family is related to the spy, and the spy will be notified after receiving the urgent contact letter, and the other is that the postman is the spy. As long as you read this letter, you will know that the downline is urgently making an appointment with me."

"Is there any more?" Chu Lingyun asked again.

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

"Sit down."

Chu Lingyun smiled slightly. Today he is wearing a military uniform with the rank of major, and looks very energetic.

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

This is not a precedent. People who have lurked before came to give lectures, and some even wore masks on purpose to prevent people from knowing their true appearance.

Lurking is very dangerous, and no one can guarantee that all students will not be arrested and defect in the future. If some students defect, it will be a great threat to them.

"Is there anyone to add?"

Chu Lingyun asked again, the students just now thought that the postman was actually pretty good.

Everyone has their own limitations. Not everyone can think of timeliness at the first time. Human thinking will focus on the most important information first, and often ignore side details.

In later generations, there are not a few people who look for their mobile phones with their mobile phones. He only thinks about where he put his mobile phone just now, and ignores the things in his 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 connection signal, everyone who has access to this letter may be a spy, including not only the head of the household and the postman, but also the person who received the letter, the person at the post office, etc. I think the focus of the investigation should be everyone who can contact the letter. The one who got the letter."

As soon as he finished speaking, the first student who answered showed annoyance. This student was right. Anyone who came into contact with the letter might be a spy in disguise.

What he thought just now was still too one-sided.

"Well said."

Chu Lingyun smiled, the quality of this group of students is not low, it is already 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 the instructor to give it a positive answer.

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

The thinking of the students is currently limited to the signal, and no one thinks about timeliness.

But being able to think of these has already helped to solve the case, but it needs to consume more manpower and material resources.

Seeing that no one raised their hands again, Chu Lingyun said slowly: "This letter is an emergency contact signal. Anyone who has access to the letter is suspicious, but there is one thing, the time when they have access to the letter."

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

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

"The time for emergency contact is at noon the next day, so the head of the household and the postman can be ruled out directly."

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

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

Even if it is 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 the time, he can rule it out. The intelligence work is very rigorous and does not allow such obvious loopholes.

"This is a real case. The most important thing in this case is timeliness. After our investigation, we found that there are two ways to send mail: business offices and mailboxes, but only letters in 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 the students understood that the sorter is indeed the easiest person and the earliest person who can get in touch with letters.

However, the first person to see the signal 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. If there was no fixed mailbox, there was no guarantee that the spies would definitely see the letter.

"Instructor, is the sorter a spy?"

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

No?

The students' eyes widened. From their point of view, the sorter must be a spy, so that after seeing the signal, they can meet their downline, but the instructor said no.

"The spy bought a person in the post office and gave him money every month to keep an eye on these signals. The person at the post office also bought a sorter. After the sorter sees the letter, he will notify the post office as soon as possible The person at the post office will go to the designated place to draw a signal, and the spies don’t need to have any contact with the person at the post office to know that there is an offline appointment to meet him, and who it is.”

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

There are so many spy arrangements, layer by layer, and the sorters don't know the existence of the spy, and even the people who are bribed by the post office can't see the spy himself.

In this case, the security can indeed be higher.

"Spy is really cunning."

A student lamented that the signal for an urgent appointment is so complicated, and such an enemy must not be taken lightly.

From the moment they entered school, they understood that their biggest enemy is the Japanese, and they have always regarded the Japanese as their imaginary enemy.

But what the instructors talked about before was all formal information science, such as analyzing intelligence, obtaining intelligence, stalking and anti-stalking, etc. Even if there were cases, they were dry or outdated examples, not as exciting as what instructor Chu said.

This is the real actual combat, and they feel that they have benefited a lot from just listening to this one.

"Instructor, did you finally find this spy?" A student couldn't help asking.

"I must have found it, otherwise the instructor would have said it." A student answered, and many of them laughed out loud.

"I found it." Chu Lingyun nodded with a smile, and then sighed: "Although I found it, but the enemy is too cunning, I released his downline to meet him, but the spies found something abnormal, and the downline was arrested He was killed on the spot, and the spy also committed suicide on the spot."

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

Fortunately, the entire Dujuan team was taken away by him, making up for this regret as much as possible.

"This can make him commit suicide." The students were stunned.

In their view, their instructors did a very good job. It was not easy to find so many people and find the spies, but they didn't expect that they didn't do all the work.

The spy is dead, and the work may even become a deed.

And such a case, the instructor actually brought it up directly, and it was explained in the first class, which made many students admire Chu Lingyun even more.

It is even rarer for such an instructor to speak out about his own mistakes.

"The spies are far more difficult to deal with than we imagined, so after you graduate, no matter where you fight, you must not underestimate our enemies, and you must deal with them with full energy."

Chu Lingyun said slowly, he had thought carefully about what to say first during the lecture.

This case is very educational, so he used it as the first thing to talk about.

"Group 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, Zuo Xuan must have something important to come here at this time, otherwise he would not come to disturb his class.

The first thing Chu Lingyun thought about was whether something would happen to the headquarters, and Ni Qian and Chu Yuan must have made trouble just after he left.

"Come with me, Deputy Director Yu wants to see you."

Zuo Xuan said in a low voice, the telegram is top secret, Deputy Director Yu didn't tell Zuo Xuan the content of the telegram, this is the special arrangement of the seat in the telegram.

Only Deputy Director Yu and Chu Lingyun knew this news, and no one else was allowed to tell it.

Protecting your own inside line is also very important.

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

Chu Lingyun took the initiative to ask: "Deputy Director Yu, did something happen at the headquarters?"

"It's something."

Deputy Director Yu nodded, and handed over the top-secret telegram sent by the chief to Chu Lingyun for reading.

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

"The Japanese are only good for this, but since they have noticed you, they must be careful in the future. He Nian has sent someone to protect you. You should stay in the school for a few days and don't go anywhere."

After burning the telegram, Deputy Director Yu slowly said that Chu Lingyun was being watched by the Japanese. According to the nature of the Japanese, there will be many means to deal with him.

And if you don't achieve your goal, you will never give up.

"I understand, thank you, Deputy Director."

It wasn't about Nixiu and Chu Yuan, Chu Lingyun was quite relieved, as for the Japanese dealing with him, it was already within his expectation.

He caught so many spies, and the Japanese hated him to the core. They don't need to use some shady ways, are they still Japanese?
"I will strengthen the school's vigilance, and your family members should also pay attention."

"I've already made arrangements 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 prepared in advance. It was not easy for the Japanese to find out where his family was going. Only Smith knew the exact whereabouts of his family.

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

At the beginning, he told his parents not to tell outsiders about the new school, nor to their colleagues. The new school has not been successfully established.

Parents are face-saving people, and they will never show off to anyone before they have made achievements.

"Go."

Deputy Director Yu smiled and said, being able to be valued by the Japanese, even to assassinate, proves that Chu Lingyun did a good job and really hurt the Japanese.

Being able to be so valued by the enemy these years is also an affirmation of his own achievements.

Although the first class was interrupted, Chu Lingyun still talked a lot after returning home, including the case of Yang Jian.

Spies are cunning and will arrange doubles. When you encounter hidden spies in the future, you must be cautious and check more.

"Leader, here it is."

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

Shen Hanwen brought some biscuits and a pot of meat, and the two sat facing each other to eat.

When Chu Lingyun was in class, Shen Hanwen listened to the lectures with the others, and when Chu Lingyun was not lecturing, he also went to listen. Shen Hanwen had not received systematic training, so this time it happened to help him recharge his batteries.

"The Japanese pretend to be poor, but in reality they can't bear that much suffering. Silly Er, for his own food, let people pretend to be his relatives, pay for the sesame seed shop in advance, and give him something to eat as long as he goes."

Shen Hanwen bit the biscuits and ate the fatty meat, and suddenly remembered the spy fool in the previous case, and couldn't help but say.

This is not only the case with Sha Er, but also Liu Wu.

Occasionally, Liu Wu would secretly get some delicious food for a tooth-beating festival. Only their team leader, Yang Guang, usually only ate some ordinary food and never made any mistakes in this regard.

"They are also human beings, and as human beings, they will have weaknesses. Who can bear the real suffering."

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

It was really bitter, the roots and turf were all eaten up, and there was no food to eat, even the leather belt.

In terms of perseverance, no one can compare with these great predecessors.
