After this method appeared in Lin Xueyi's mind, she could no longer sit still. Then, she didn't listen to the conversation of everyone, and her eyes swam around, trying to search for something in the living room.

She wanted to know where the Tao Mansion phone was installed.

What she urgently wants to do now is to contact Mo Xihan.

Soon, she saw a phone call on a solid wood table in the living room. But at this time, outsiders were present, and Lin Xueyi was inconvenient to make a call request.

Just as Lin Xueyi was sitting on pins and needles and was distracted, he saw Tao Jiaqu slowly standing up and coming to the phone directly. He lifted the microphone with one hand and was about to dial the other hand, but suddenly hesitated.

Lin Xueyi immediately understood that he did not want to disclose the content of the phone number in front of everyone, so he said to Tao Ruoge openly: "Ruoge, I will tell you something, let's talk about it."

Du Yulong was as careful as his hair, and he also stood up and walked out the door.

Lin Xueyi pulled Tao Ruoge to the door and whispered: "Do you still have a phone number in your house? I need to borrow your phone number in urgent need of something."

"Yes, there is one restaurant, and my grandfather's study also... I'd better take you to the restaurant."

Tao Ruoge was very tactful and did not follow Lin Xueyi. He just sent her to the restaurant door and left by himself.

After recalling the phone number Mo Xihan told her, she directly called Mo Xihan's office.

The phone call was called and then Mo Xihan's voice came from the other side of the phone: "Who is it?"

"Teacher Mo, it's me, Lin Xueyi."

Mo Xihan's voice immediately lowered and asked, "Xueyi, are you asking me for trouble?"

"I came up with a way to contact Lei Yuan's organization..."

Mo Xihan said curiously: "Tell me, let me see!"

"Use the radio!" Lin Xueyi answered without hesitation.

Mo Xihan immediately seemed full of doubts: "Do you want to use our radio station to contact Chongqing?" As soon as he finished speaking, he found the crux of this method and said disdainfully: "Is this method not working?"

"Yes!" Lin Xueyi blurted out, with a little excited tone.

"Do you want to send a message in a clear way?"

"No need to know clearly!" Lin Xueyi still seemed very excited.

Mo Xihan was even more curious, "How is this possible? How do you compile the message without a password?"

Before Lin Xueyi could reply, Mo Xihan immediately asked, "So, have you mastered the other party's password?"

"Yes, I have a password they are using on hand!"

"What are you kidding? How could you have such an important thing?" Mo Xihan's words were full of distrust.

"I didn't lie to you! Last time Lei Yuan was performing a mission in the international security zone and put the intercepted passwords in my place. He didn't know my identity at the time. I thought maybe we could use it, so I secretly copied one!"

Mo Xihan suddenly understood everything and asked subconsciously: "Does Lei Yuan know that you copied the other party's password?"

"Of course it's impossible to tell him, do you think I'm a child?"

Mo Xihan changed his mind and found the loopholes in it. He refuted her without hesitation and said, "Oh, by the way, don't forget that our radio station's power is too small and Chongqing cannot reach it!"

"Don't contact Chongqing, just contact the radio station near them!" Lin Xueyi became more confident.

"Do you have a call from their radio station?" Mo Xihan asked tentatively.

"It's easy to know their radio call signs. Just turn on our radio station and filter the intercepted radio waves according to the password. If the telecommunications content can be deciphered through the password I have in hand and the words are expressed, it will be possible to prove that the radio wave is output by a certain radio station organized by Lei Yuan? Then, based on the frequency of that radio station, can we send it a report?"

Mo Xihan was filled with praise: "You little girl, you have learned to think and have made great progress!"

Lin Xueyi's tone was quite proud, "It's not because of the situation!"

"Okay, leave this matter to me, don't participate. You prepare for it. I will try to get rid of the enemy I followed and get the password book back to you..." Mo Xihan said and reminded him again: "It's an extraordinary period. You must be careful during this period. The password book must not fall into the hands of the Japanese. I feel that the Japanese have recently been eyeing me. If you appear at my house in the morning, you may have entered the Japanese's sight. From today on, you must be highly vigilant!"

"Okay, I'll notice."

...

Yuichi Kawamoto did not participate in the capture of Lei Yuan, so he and Ohashi Yu came to the Eagle Organ early after breakfast that morning.

Nearly twenty minutes have passed since working hours, Kawamoto discovered that many people in the Eagle Agency did not appear on time today, especially the Operations Office. In addition, even the head of the agency, Morikawa Jung-chan, who had always been up early and had to appear in the office ten minutes before work, was nowhere to be seen.

The reason why Kawamoto found Morikawa did not come was because shortly after work, he received a call from the logistics agency of the Security Command. The phone asked the Eagle agency to send someone to get a set of equipment that had just arrived in Nanjing from Shanghai. To receive this set of equipment, the commander of the agency General Morikawa must have the handwriting of the head of the agency. Therefore, after receiving the call, Kawamoto came to Morikawa's office, but no one responded after knocking for a long time, until a person in charge of the agency's convoy happened to walk out of the Finance Department beside him. Seeing this, he reminded Kawamoto: "Don't knock, the general commanded an arrest operation last night and came back late at night. He should still be sleeping now!"

Kawamoto left Morikawa's office in a bad mood. As soon as he went down the stairs, he saw Morikawa coming in a hurry with a briefcase.

Kawamoto immediately cut Morikawa at the entrance of the stairs and said, "God General, I've been looking for you!"

"What's the matter with me?" Morikawa took a step up to the second floor, took out the key and opened the office door.

Kawamoto took out an application form for the item and placed it on the desk in front of Morikawa, saying, "The logistics agency of the Security Command called and asked us to go and collect a set of equipment quickly. So we need to sign the general before we can pick up the goods."

Morikawa took out his pen, stared at the application form, and immediately became excited, "These people from the logistics agency are very efficient in their work. They just informed us a few days ago. I thought it was just a verbal promise, but today it arrived!"

Kawamoto quickly asked Morikawa curiously: "This set of equipment is only numbered but not specified. How could the general know what it is?"

Morikawa showed a look of smugness, "The logistics agency is really a timely help! This is a set of the latest radio wave detectors, specially purchased from the German country!"

"Is it the radio listening facility that the general mentioned to me yesterday?"

"That's right, it's it!" Morikawa smiled and glanced at Yuichi Kawamoto, "Kun Kawamoto, with this set of equipment, don't make excuses with me again in the future. You have to lead your team members immediately and handle a few beautiful cases for me in the near future, and dig out the radio station where the enemy is hiding in Nanjing City!"

Kawamoto looked suspicious, "This equipment is so magical? Will it work immediately?"

"Of course, this is the latest product of the German National Lawler Company. At present, it is also the most advanced in the whole world!" Morikawa quickly signed his daimyo on the application form, put the pen away, and continued: "The Germans were unwilling to provide this technology to us from the beginning. The Hitler government is quite conservative... It is still the people from the Imperial Ministry of Foreign Affairs who have a solution, and I don't know what method they used to reach an agreement!"

Kawamoto's face looked very interested, "What is the advanced of this listening device? Please give me advice!"

"Its two functions use the most forward-looking technology in the world. One is that it can immediately measure the specific direction of the wave source for the radio signals that appear. What's more amazing is that it can be accurately within a range of less than one kilometer, which means that there is no need to adopt the stupid method of partition power outage. Think about it, isn't it a bit of a piece of cake to find a suspect in such an accurate area?" Morikawa paused and said: "What's more important is that this set of equipment is small in size and easy to carry, and can be installed in small vehicles. Kawamoto imagines that a movable car can limit the range of suspect signals? It can even be narrowed to a range of 500 meters! Of course, I also heard from the people of Iwai Mansion that this information depends on the actual situation. After all, we have never used it!"

Kawamoto's eyebrows were dancing, and he was very excited in his words: "It's great, it seems that the doomsday of the enemy's platform has arrived!"

Morikawa was quite infected, and the atmosphere was warm, as if victory was right in front of him. Morikawa seemed to be admonishing a naughty child: "Kun Kawamoto, from now on, you are not allowed to find objective reasons for me again!"

Kawamoto responded humbly: "Absolutely not!"

Morikawa continued to say proudly: "It also has a second powerful function that can accurately measure the frequency of the other party's radio station!"

"This is not a creative move, right? The listening facilities we are using now can also be judged!"

"Kun Kawamoto, you have to remember that what I said is 'accurate'!" Morikawa glanced at Kawamoto contemptuously and talked: "In the past, the listening equipment could only roughly outline the frequency of the signal, but not accurately. But now it is different. Once this set of equipment is put into use, it can immediately be used to fully distinguish and mark all the signals of the exchange and radio waves in Nanjing City. What a great breakthrough! Moreover, we can also distinguish the power of the other party's radio station based on the frequency. You might as well think deeply. If it is a high-power radio station, does it mean that it covers a large radius? With such thoughts, is it easy for us to judge the enemy's primary and secondary radio stations? This further determines the leadership and subordinate status of the enemy station?"

Kawamoto nodded repeatedly.

At this time, Morikawa thought of the successful arrest last night, and became more and more energetic, and could not suppress his inner joy. He had long forgotten all his frustration, and a thought emerged in his heart.
Chapter completed!
