When I came out of Chicken and Goose Alley, it was already noon.

The information Chen Gongshu gave himself just now contained too much personal information about Cao Guangyuan.

Geng Chaozhong didn't expect that Lao Cao was so complicated.

I have been to Japan, I have been to the Soviet Union, first with Hu Hanmin, the earliest rightist of the Kuomintang, and later with Wang Jingwei, a leftist, and then to the Party Investigation Department to Xu Enzeng as a spy, and now, he is the director of the Nanjing Political Security Department - this political security office has always been the territory of the Baoding department.

What's more, his final identity is likely to be a Communist!

The complexity of this person's background and the unpredictability of his identity are really breathtaking.

Recalling that on the Sea Dragon, Cao Guangyuan's persistence in discussing the concept of communism with himself, the courage and fearlessness when he fought side by side, and the pride of laughing and talking about the sea, his round face and round eyes seemed to appear in front of his eyes again.

Is he really the head of the Nanjing underground party of the Communist Party of China?

If so, do you really want to kill him?

Geng Chaozhong understood that Dai Yunong let himself take over this case, although it was not necessarily screening, but it must be a test.

Under Dai Li, having compassion for the enemy is a big taboo!

Dai Yunong sees the weakness of his classmates clearly, he likes and appreciates his own ability, but he is dissatisfied with his weakness.

But on the other hand, is this kind of human touch also an aspect of Dai Yunong's trust in himself?

A person, whether he is a spy, a butcher or an executioner, does not want to get along with a ruthless person, and Dai Yunong does not like his weakness at work, but he likes his weakness when he is with him.

If he ends up being as ruthless as other spies, will Dai Yunong really be satisfied?

Not necessarily, for example, Yu Lexing, although Dai Yunong was also dissatisfied with his weakness, but from beginning to end, he respected him very much, treating him as his friend, rather than treating him as a tool like others.

This is really a contradiction!

Geng Chaozhong shook his head, trying to get rid of this complicated thought and quickly return to the world of reason.

In any case, Lao Cao must be investigated, and he must be seriously investigated, and as for whether he is a Communist Party or not, there will naturally be a solution at that time.

Back at school, Geng Chaozhong went directly to the infirmary, and the reason why Peng Wumin arranged for him today was acute dysentery, so he had to go to the infirmary to get some medicine, so as not to be seen by a few classmates.

After taking the medicine, going back to the dormitory and lying down for a while, and making a few eyewitnesses, Geng Chaozhong took advantage of the night to return to Chicken and Goose Lane.

Today is still a full day of tactical lessons, but in the evening, there is a secret communications lesson.

However, in this secret communication class, it was not only Guo Xiaoxian from the sixth group who listened to the class, but in the small classroom, other group members, including Zou Zheng, came to observe.

The clock pointed to six o'clock in the evening, and in the dim light, a fat man wearing a scarf and a robe walked into the classroom.

"Hello students, I am from Germany, my name is Schulz, and I will teach you today's secret communication class."

The fat man introduced himself in broken Chinese.

Everyone looked at the fat man in front of them with curiosity - not because he was German, but now that China and Germany are cooperating, the artillery instructors and surveying and mapping instructors in the Whampoa Military Academy are also Germans, and everyone has long been surprised.

Everyone wondered why this German had to cover his face.

Zou Zheng stood up and explained:

"Mr. Scholz covered his face because of the secrecy regulations, he had an official status in Germany, limited to the Treaty of Versailles, and German regular soldiers were not allowed to participate in any military exchanges. So, you don't have to be surprised by this. ”

Zou Zheng explained the reason why the instructor covered his face, and everyone nodded understandingly.

The Treaty of Versailles after World War I aimed to weaken Germany, and the treaty strictly forbade the Germans to develop their military, so the German instructors in the military schools were all civilians.

"Alright, let's start teaching." The German instructor spoke.

"The secret communications course covers a wide range of subjects, including the translation and production of cipher codes, radio and telecommunications transmission, and general knowledge of intelligence, including disguise, enemy situation surveillance, and other subjects.

But for everyone, it doesn't need to be so complicated to learn, we only need to learn some basic knowledge, and we can deal with most situations.

Today I'm going to talk about the main way of connecting.

There are three main ways to connect intelligence personnel:

1. Meet directly through the designated meeting place and codeword.

Second, communicate through the dead mailbox. The so-called dead mailbox is a place agreed upon by both parties, where the tools, funds, intelligence and other objects necessary for intelligence activities are hidden, waiting for the other party to access them.

3. Combination of the above two methods. For example, hiring a third party to connect with another third party to transmit signals can take many forms, such as passing information through dancers, beggars, etc., and using complex designs to make the tracker consume a lot of manpower to ensure safety.

Below, I will introduce the specific joint method in detail, the first ......."

The German fat man is naturally Geng Chaozhong - after careful consideration, he decided to dress up as a foreigner, and it is not easy to be discovered by these classmates who get along day and night.

The weird tone and the obscured face can perfectly hide this identity.

As for the curriculum, it is the basic course when I studied information science in the military school, of course, the textbook must not be memorized, and I can only write a crash lecture based on memory and practical experience, but for these people, it should be enough.

Sure enough, as Geng Chaozhong talked eloquently, including Zou Zhengnei, everyone's eyes lit up, this German spoke very clearly and methodically, and the examples he gave were also very detailed, and he had very rich experience in intelligence work at a glance.

Everyone took out their notebooks and started taking notes.

The class passed quickly, and when it came to the end, Geng Chaozhong closed the handout and said:

"You may be curious about my face, and there is no denying that when I came in today, I was put on makeup, and from the next class, I will continue to remove the disguise on my body, and when the last class comes, I will let everyone see my true face, and I hope everyone will not be too surprised by then."

Also, if someone can draw my portrait in advance, then I will give him a reward, a reward that will definitely satisfy you. ”

The German instructor's mysterious tone aroused everyone's strong curiosity.

Astonished?

What's there to be surprised about?

Could it be that this German instructor is pockmarked with a pockmarked face? Or, he is not a man at all, but a woman?

Everyone began to speculate about the true appearance of the German instructor.
