Spy Shadow

Chapter 228 The first lesson

Secretary Qi went to send the report, and the director looked at the message from Jiang Tengkong again.

It feels so good to have one of our own among the enemy. We can know what they are doing at any time, unlike before, where we were blind and could only passively defend.

The importance of roses has been shown.

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 only 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 within a 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 outstanding.

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 particularly excited.

"Everyone looks 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 had ever talked about this case, so Chu Lingyun brought it up as part 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 think there are 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 I see this letter, I will know that my downline is urgently making an appointment with me."

"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 was not a precedent. Personnel who had lurked before came to give lectures, and some even wore masks to prevent others from knowing their true appearance.

It is very dangerous to lurk, and 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 are looking for their mobile phones. He only thinks about where he put his mobile phone just now and ignores what he has in his hand.

"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, the 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 came into contact with the letter might be a spy in disguise.

What he just thought was too one-sided.

"Well said."

Chu Lingyun smiled. The quality of this batch of students was not low. It was close to the truth to think of this.

The second student who answered was shocked. 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 unwilling 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 showed surprise.

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 the students thought about the time it would take to send a letter.

Even in the same city, it is impossible for the head of 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 was possible to access the letter outside of time, he could rule it out. Intelligence work was very rigorous and did 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 it was explained clearly, all students understood that sorters were 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 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 sorter must be a spy, so that after seeing the signal, he can meet his 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. This 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 location to draw a signal, and the spy will know that there is an offline person who wants to meet him, 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 were so many spies arranged, one after another, and the sorters didn't know the existence of the spies, and even the people bribed by the post office couldn't see the spies themselves.

In this case, security can indeed be improved.

"Spies are so cunning."

A student sighed and said that just a signal for an emergency appointment was 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.

This is the 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 nodded with a smile, 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 was indeed Chu Lingyun's regret.

Fortunately, the entire Du Juan 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.

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

It is even more rare 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 was 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 was in class. Zuo Xuan must have something important to come here at this time, otherwise he would not have disturbed 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 and 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 knew this news, no one else was 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 Chu Lingyun the top-secret message from the Director 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.

"That's all the Japanese can do, but since they have noticed you, you must be careful in the future. He Nian has sent people to protect you. You will stay in the school these days and don't go anywhere."

After burning the telegram, Deputy Director Yu slowly said that Chu Lingyun was being targeted by the Japanese. According to the Japanese's temperament, there would be many means to deal with him in the future.

And I won’t give up until I achieve my goal.

"I understand, thank you, Deputy Director Yu."

It was not because Ni Loach had something to do with Chu Yuan, so Chu Lingyun was relieved. As for the Japanese dealing with him, he had already expected it.

He has captured so many spies, and the Japanese hate him to the core. If he doesn't use some shameful method, are they still Japanese?

"I will tighten 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 returned to the United States a long time ago, and he doesn'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 lead to ridicule.

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 Yang Jian case.

Spies are cunning and will arrange stand-ins. When you encounter a lurking spy in the future, you must be cautious and check frequently.

"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 his batteries.

"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 the sesame cake and eating the fatty 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 humans they 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.
