Zhang Guanglin's words gave Lu Chengzhou a wake-up call.

Ma Yuzhen must contact Liu Jinghua as soon as possible, which is her duty.

Zeng Zilian died, and Liu Jinghua had been waiting for someone from the military commander to contact him.

When Liu Jinghua first joined the military police detachment, he lived in the military police detachment.

In order to facilitate communication with the military commanders, he later moved out, which greatly facilitated his communication with the military commanders.

Today, a batch of equipment arrived in the telecommunications room, however, Masahiro Matsumoto did not inform him.

He's the deputy director of the telecommunications office, so what equipment does he have to guard against?

Liu Jinghua guessed that this batch of equipment may be related to the military radio station.

Liu Jinghua is an expert in telecommunications, and when he thinks about problems, he will first think about this aspect.

Even the equipment that you have to keep secret is supposed to be the equipment of the detective radio station.

Ma Yuzhen, like Zeng Zilian, disguised herself as Liu Jinghua to meet.

knocked on the door with a code outside, and after Liu Jinghua opened the door, Ma Yuzhen made a code with him.

"It's great to have been waiting for you to come." Although Liu Jinghua didn't recognize Ma Yuzhen, as long as he was sent by the military commander, it was enough.

After learning that Zeng Zilian was martyred, he had been waiting for the military commander to send someone to contact him.

Hearing the secret signal from outside the door, Liu Jinghua was actually a little excited.

"Mr. Liu, my surname is Ma, and I will contact you in the future. Today is the first time we have met, and I took the liberty to visit. In the future, try not to meet at your residence. Ma Yuzhen said slowly.

If Lu Chengzhou was here, he would be surprised.

Ma Yuzhen is no longer the young and hot-blooded revolutionary youth, she has become calm and introverted, and her tone of voice is very suitable for her current identity.

"Some equipment came to the telecommunications room today, but the Japanese were very strict and did not allow the Chinese to approach." Liu Jinghua nodded, and Ma Yuzhen's words made him suddenly feel at ease.

Haigu Station is still the same Haigu Station, and it has not changed dramatically because of Zeng Zilian's death.

"You're the deputy director of the telecommunications office, and you keep it a secret?" Ma Yuzhen said in surprise.

Since serving as the deputy team leader, she has realized that she doesn't know much about Haigu Station.

In the past few days, she has learned more about the situation of Haigu Station than in the previous two years combined.

Although she has not yet been connected with the organization, she believes that the organization will hope that she can stay in this position.

Ma Yuzhen is also confident that she will do a good job as the head of this intelligence team.

Now Ma Yuzhen deeply understands the latent value.

As the head of the intelligence team, Haigu Station has no secrets about her.

"The Japanese have always distrusted the Chinese. To put it mildly, they guard against me like a thief. Liu Jinghua sighed and said with a wry smile.

The Japanese are selfish and arrogant, and they do not trust the Chinese, and the new equipment, he, the deputy director, do not say touch, he does not even see it.

"Either way, the Japanese are certainly not at ease." Ma Yuzhen said slowly.

"Yes, I dare to conclude that these devices must be used against the military radio station." Liu Jinghua thought about it and said firmly.

"Against the military radio station?" Ma Yuzhen frowned.

As Lu Chengzhou said, Haigu Station can't have any more accidents.

"As long as you have a specific device, you can detect the location of your station." Liu Jinghua is an expert in telecommunications, and he has always been very interested in the knowledge of telecommunications.

"What device is so powerful?" Ma Yuzhen said in surprise.

She has no professional training, and she has only just gotten a glimpse of the way in the Shude Primary School training class.

She learned to send and receive newspapers, learned a little in the training class, and learned more from Zeng Zilian.

"There are a lot of equipment like this, for example, there is a special monitor, there is also a weekly correction station, long-distance direction finder, etc., as long as these equipment are used properly, it is easy to find that there are no unregistered radio stations. If the report takes too long, or if it is always in the same place, the location of the station may be exposed. Liu Jinghua reminded.

Liu Jinghua provided the information, Ma Yuzhen quickly informed Lu Chengzhou.

She knew Lu Chengzhou's "real" identity, and if the situation was urgent, she could even go to Lu Chengzhou's house.

However, they must strictly follow the group discipline, and like Zeng Zilian, they still choose to connect in the Daguang Cinema.

The business of the cinema, this time is a little worse, they can choose a corner where no one is around.

To others, they look like a pair of lovers in love, and the two whisper next to each other and don't attract attention.

"The 'phone' said it might be for our radio station." Ma Yuzhen whispered in Lu Chengzhou's ear.

"Telephone" is the code name he gave Liu Jinghua, Liu Jinghua is the most confidential intelligence officer of Haigu Station, and they must not talk about Liu Jinghua's name here.

"I'm worried about that too." Lu Chengzhou said with a sigh.

"What to do? It is recommended to reduce the number of calls, extend the interval time, and minimize the call time. Ma Yuzhen whispered.

If the new equipment brought in by the gendarmerie detachment is really against the military command radio station, there is no other way but to minimize the frequency and time of sending reports.

"Report to the family, and contact once a week in the future, and each time the report should not exceed fifteen minutes." Lu Chengzhou said slowly.

"The phone also suggested that in order to avoid the code being deciphered, the tone and words of the sender should be paid special attention." Ma Yuzhen said again.

Almost all of them had their own accustomed diction and style of writing, and once the telegram was deciphered, the enemy could infer from these the circumstances of the person who sent the telegram.

"Is there anything you can do?" Lu Chengzhou asked, almost all the telegrams at Haigu Station were drafted by him.

Zeng Zilian would also help him draw up telegrams before, but in the capacity of "flame", he sent the telegrams to the headquarters alone, and he could only forcibly change the idiomatic words.

"I think we can hand over the content of the counter-telegram to Lin Fan and let him write to his family with his own writing habits." Ma Yuzhen thought for a while and said.

It's like a person's handwriting, falling into the hands of an enemy, and the identity of the writer can be deduced.

But what good is it if someone else has copied it again, even if you know the handwriting?

"This is a good solution, and it will be done in the future." Lu Chengzhou bowed slightly, Ma Yuzhen's method was still good.

It's just that some confidential telegrams, such as the one sent by Lu Chengzhou to the headquarters alone, can only be done by himself.

When Lu Chengzhou arrived at the gendarmerie detachment the next day, he found that the truck of the gendarmerie detachment had a shelf on it and covered it with a thick tarpaulin.

"Yamaguchi-kun, are you going to put a raincoat on the bus?" Lu Chengzhou saw Shizuo Yamaguchi jump out of the car, put his hand on the top of his head, and quickly ran into the house.

"If you don't put up a shed on it, you can't carry out the mission." Shizuo Yamaguchi glanced at Lu Chengzhou and said casually.
