In the early 20th century, radio technology was changing rapidly, especially the large-scale role of electronic tubes, which made the radio performance better and better.

However, the electronic tube is fragile and easy to damage, so after the user places the radio, it will not move under normal circumstances to avoid vibration and damage internal parts.

Unless it is because of moving or other unscrupulous reasons, you will risk moving the radio. After all, a radio is expensive, but the Yuan family has not moved recently, so why did Yuan Chuyu do this?

While thinking, Wu Chunyang left the bookshelf and walked to the desk to take away all the items on it. He asked the spy to bring talc powder, then grabbed it and put it in the palm of his hand and blew it.

Under the action of the airflow, the powder spreads evenly, and the crimson desk immediately covered with a thin layer of talc powder. Then, four shallow pits were exposed in the upper right corner of the desk, the size and distance were the same as the footrest at the bottom of the radio.

Wu Chunyang's eyes lit up. While asking the spy to take photos and collect evidence, he hugged his arms and began to think.

Yuan Chuyu moved the radio from the bookshelf to the desk, probably because he had to record something with paper and pen. At the same time, the radio sound was very small and needed to be placed close to it to hear clearly.

It seems that the other party doesn't want his parents to hear the content on the radio, otherwise he can turn the sound up, and there is no need to carry a machine weighing dozens of pounds and walk around.

Judging from the traces on the desk, this behavior has lasted for a long time, and listening to the radio in secret is the daily work of spies. Could it be that the two departments’ identification is wrong and there is something wrong with the Yuan family?

Wu Chunyang walked out of Yuan Chuyu's bedroom and said to Yuan's father and mother: "Two, when was the radio in the room enough to buy?"

Yuan Hansen and Lu Wan looked at each other, not understanding the intention of the spy asking this question, so they hesitated for a moment, and Yuan Hansen replied as the representative.

"I bought it from a German trading company half a year ago and spent more than 100 Sichuan Yang. Master, is there any problem with the radio?"

"No, I'm just a little curious." Wu Chunyang shook his head and smiled again: "You can't bear such an expensive thing?"

When talking about this, Yuan Hansen's expression was right, and he stood up proudly.

"Chuyu is quite talented in learning languages ​​from various countries. As a parent, he naturally has to provide the best conditions for his children. Just a radio is nothing to us."

Wu Chunyang suddenly realized that Yuan’s father was both a teacher and a gentry. In the eyes of such people, as long as it was beneficial to the coursework, it was worth it.

After thinking about it, he asked the female spy to take Yuan’s mother Lu Wan out, sat opposite Yuan Hansen, looked at the other party’s eyes and asked a few things.

One is the situation of the Yuan family, such as how many generations have they lived in the mountain city, what relatives are there, where are their hometowns, etc.

The second is to ask Yuan Hansen about his experience when he was young, where he went, and who he met.

Third, I confirmed with Yuan Hansen whether I had left the mountain city for a long time.

Both of these questions have been investigated, but Wu Chunyang still wants to listen to Yuan Hansen's answer again. He believes in his professional ability. If the other party lies, he will definitely not be able to hide it from his eyes.

Unfortunately, Yuan Hansen's performance is impeccable, and with witnesses, testimony, and historical archives as circumstance, it can basically rule out that Yuan Hansen's suspicion of being involved in spies.

But Wu Chunyang was not disappointed. He reached out to take the other party's file from the small spy, looked at the content inside and looked up and asked.

"Mr. Yuan, the archives record, you know Red Russian, right?"

"good."

Yuan Hansen admitted frankly, and said with a very emotional tone: "When we were young, we were successful in our lives, and the general administration advocated uniting with Red Russia, so many people learned Red Russia in order to build the country as soon as possible."

Well, it’s a bit dangerous to discuss this matter. Wu Chunyang decisively changed the topic and returned the conversation to the case itself.

"So Mr. Yuan, have you ever heard the young master listen to Red and Russian radio or radio from other countries at home, and record the broadcast content with paper and pen?"

Yuan Hansen was stunned. After thinking about it carefully, he shook his head: "I have never seen Yuan pay attention to equality at home. Even if Chuyu is my son, I and Zhuo Jing will not enter his room at will without his permission, but..."

Halfway through, Yuan Hansen stuttered for a moment, and Wu Chunyang hurriedly asked.

"But what?"

Yuan Hansen frowned and said with some uncertainty: "A few months ago, Chu Yu came back from school on holiday, and went to the city with his middle school classmates early the next morning.

After he left, Zhujing went into the house to clean it. He saw a piece of paper on the desk with a red Russian written on it. By the way, Zhujing is a student from Qiming Girls' School in Shanghai and knows some red Russian."

Wu Chunyang was excited and after two days of searching, he finally found something and immediately asked about the content in red and Russian.

Yuan Hansen smiled bitterly: "Sir, Zhuo Jing just mentioned it at that time. I didn't care. If you want to know what was written on the paper, please let Zhuo Jing answer."

This answer is reasonable. There are many such small things in life, and it is normal for the other party to remember them. Wu Chunyang thought about it and shouted outside the door.

"Come, please come."

Soon, Lu Wan sat down on the sofa again. She was also questioned outside just now. A small spy nodded to Wu Chunyang, saying that she did not find any flaws in the question.

Wu Chunyang's smile remained unchanged, and he told Lu Wan that note with a smile. Lu Wan didn't think too much and said without thinking.

"The note was written on the note. You know, this was a bit taboo, so I burned the note. Chu Yu even blamed me when he came back."

After listening to her answer, Wu Chunyang did not listen to the matter of privately listening to the Red Russian Radio, but asked the other party to write the content of the press release. There were too many people in the mountain city to control such matters.

Lu Wan is worthy of being a talented girl from Qiming Girls' School. She has an outstanding memory. After a moment of recollection, she picked up the pen and started writing.

"Qiwa City Radio Station communication, Mosk solemnly warned Berlin..."

Wu Chunyang stretched his head and found that this was a Red and Russian press release targeting Germany. Who would be interested in this matter?

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! German?

Japanese?

Or American?

Besides, as long as there is a radio, anyone can listen to similar news. Yuan Chuyu doesn’t need to record it secretly. Could it be that this is an encrypted message?

Hide secret instructions in seemingly normal broadcasts is a common means for intelligence agencies in various countries to issue orders to intelligence personnel lurking overseas and deliver messages.

Could it be that Yuan Chuyu deciphered the encrypted information and blackmailed the relevant forces, and thus obtained 20,000 US dollars. A top student in the mathematics department who is proficient in multilingualism is capable of doing this.

On the day of his disappearance, Yuan Chuyu met with someone with his laptop, and was preparing to extort again, but the other party became angry and chose to silence him.

Holding the note, many speculations popped up in Wu Chunyang's mind, and the more he thought about it, the more he felt that this was the fact.

But what about the evidence? No matter how good you think without evidence, it is useless. The deputy director will not listen to him "telling stories". He must find the suspect first. By the way, bank! Letter!

Wu Chunyang suddenly stood up and ordered the spies: "Apply to the headquarters to send more personnel, you must protect Mr. Yuan and Mrs. Yuan."

He was worried that if the suspect suspected that Yuan Chuyu had a backup plan and had the idea of ​​using Yuan’s father and mother to threaten the other party, then Yuan Hansen and Lu Wan would be in danger, and this matter would have to be guarded against.

After arranging the security work of Yuan’s house, Wu Chunyang quietly left from the back door, walked around for a few times before entering another courtyard. This place was a temporary surveillance point, and the situation in the gate of Yuan’s house and nearby streets and alleys can be clearly seen from here.

At the wall inside the courtyard, three small spies lay on the wall with their p-thighs sticking out, looking out through the narrow gap. Their posture was a bit funny, but only they knew the heart. After monitoring for several hours, the surveillance personnel were often so tired that they couldn't straighten their waists.

Wu Chunyang inspected the surveillance site, found no problems, and patted the shoulders of the spy's small leader with satisfaction, and then skillfully bought people's hearts.

"It's done well, please remember it and let the general affairs officers give more extra salary (bonus) to the brothers who give field trips this month."

"Thank you, Director."

There were ups and downs in the yard, and the sound was not loud but very excited. Everyone was holding their heads for what they did, except for their feelings for their country, they just wanted to support their families.

The spies with high morale were monitoring Yuan's house in shifts. It was soon in the afternoon. A postman hummed a small song and rode his bike to stagger from a distance.

The three little spies on duty were drowsy. When they saw the postman, they woke up immediately. One turned around to report the message, and the other two stared at both ends of the road.

"Li Junfu got on the boat

The same boat girl is stubborn…”

The postman in black uniform rode and sang while riding. He took out the letter from the canvas bag on the beam with his right hand, and stuffed it into the mailbox of the residents on the street without looking at it. What's amazing is that he didn't send a single letter wrong.

But the spies don't care about the professional skills of the postman, they care about whether anyone is following them.

Assuming that the suspect already knows the existence of the letter, what the other party will do is to snatch or steal the letter.

If this goal is to achieve, determining whether the environment is safe and the status of the letter delivery is an essential link, the postman becomes the best target for the suspect.

After surveillance hole, the little spy held the camera and took all the faces of pedestrians, but as he patted, a passerby with his head down caught his attention.

Because no matter how you take a photo, this person can use the surrounding obstacles to avoid the camera perfectly, the shop's signs and guitars, the roadside signs and other pedestrians, and all items become the other party's cover.

"Director, there is a situation!"

Hearing the warning, Wu Chunyang rushed over a few steps, put his eyes in front of the hole, and at the same time, the reminder of the little spy sounded in his ears.

"At nine o'clock, 50 meters away, male, slightly fat, royal blue top, black pants, about 1.65 meters tall."
