This time, Lin Fan brought two sets of communication passwords, one of which was for Haigu Station and the headquarters, and the other was the password for matches and the headquarters.

"It's okay for you to know about it." Lu Chengzhou said slowly.

As the director of the radio station of Haigu Station, he is destined to have many things that cannot be hidden from him.

But Zou Jing and An Mengbo are not, Zou Jing is a newspaper operator, just sending and receiving newspapers, An Mengbo is an internal transportation, they belong to the real internal office.

Lin Fan, on the other hand, should be classified as a confidential officer.

As the director of the radio station, he is not only responsible for translating and decoding telegrams, but also for transmitting telegrams.

Zou Jing is a newspaper operator, and her job, in addition to taking care of Lin Fan's life, is basically to revolve around the radio.

"Yes." Lin Fan said busily.

"Webmaster, here's your new password." Lin Fan took out a small notebook, wrapped it in kraft paper, and sealed it with wax.

"Okay." Lu Chengzhou took the codebook, in fact, he would only use this codebook once.

As Liu Jinghua said, the codebook, wavelength, and call sign must be changed frequently.

The codebook cannot use this kind of special codebook, but find a commonly used book, even if it is discovered, the enemy cannot be sure, this is the codebook of the military commander.

After receiving the latest telegram from Haigu Station, Mao Shanyan almost couldn't believe his eyes.

He didn't know if Dai Li was still in the office, so he hurriedly trotted to Dai Li's office.

Outside, I happened to see Dai Li holding a briefcase, ready to go back.

"What's wrong?" Dai Li asked in surprise when he saw Mao Shanyan in such a hurry.

"This is a telegram from Haigu Station with the latest password." Mao Shanyan handed the telegram in the folder to Dai Li.

"Let's go, let's go inside." Dai Li took out the key and opened the office.

"It's crazy that Flame knows that the password has been cracked, and even sends frequent reports." Mao Shanyan said urgently.

"This is cracked by Liu Jinghua, and the news has not been spread. I'll just say, the last two telegrams he sent, I always felt that something was wrong. Dai Li was not angry.

"These two telegrams, the flames were deliberately let Liu Jinghua see?" Mao Shanyan suddenly woke up.

Since Liu Jinghua has broken the code, he naturally knows the contact between Haigu Station and the headquarters.

"If you were Liu Jinghua, how would you feel when you saw these two telegrams before you came back?" Dai Li asked suddenly.

"Haigu Station is very sincere, I will be very moved." Mao Shanyan said without hesitation.

"Flame is taking advantage of this, and his trick is very clever." Dai Li said slowly.

He has long believed that Lu Chengzhou is mature and stable, and his heart is as careful as a hair.

This time to persuade Liu Jinghua, Lu Chengzhou used the telegram to let Liu Jinghua see the sincerity of Haigu Station, which once again illustrated this point.

Although Lu Chengzhou did not report in advance, Dai Li still felt very relieved.

Liu Jinghua broke the code, and even if Lu Chengzhou wanted to report, there was no way to report.

Fortunately, the headquarters was very supportive of Lu Chengzhou's work and had no intention of reproaching, otherwise, it would invisibly hurt Liu Jinghua's heart.

Liu Jinghua is currently the deputy director of the telecommunications office of the military police detachment, a position that gives him access to many Japanese secrets.

Liu Jinghua will once again serve the military commander and will be able to play a big role.

"This kid." Mao Shanyan also fully understood at this time, at that time, he still thought, why did Lu Chengzhou mention it in the telegram in order to give Liu Jinghua a bonus of 1,000?

It is also very rare for Dai Li to make such a comment.

The Japanese army attacked cities and plundered land everywhere, the national army was defeated and retreated one after another, and the military organizations in various places did not play a big role.

Before that, Haigu Station was also continuously damaged by the Japanese army.

However, after Lu Chengzhou took over, Haigu Station is slowly recovering.

He believed that after Haigu Station accumulated strength, it would definitely give the Japanese invaders a head-on blow.

"He also got the radio and the map, which I think is what the Seventh Route Army needs most." Dai Li saw the back and said happily.

"Mr. has a discerning eye, and the flame has finally lived up to Mr.'s cultivation." Mao Shanyan said with a smile.

"And the security issues raised by the flames, you give them to the telecommunications office and let them come up with a plan. Our password can no longer be cracked by the Japanese. Dai Li said with a deep groan.

With Lin Fan's smooth arrival, Lu Chengzhou finally didn't have to send a report directly to the headquarters.

He has his own secret book, he only needs to translate the code in advance, hand it to An Mengbo and transfer it to Lin Fan or Zou Jing, and then An Mengbo will send it to the dead mailbox.

After the code book was changed at Haigu Station, Liu Jinghua's progress in the gendarmerie detachment suddenly became much faster.

After only two days, he "locked" the radio wavelength of the military command.

After Masahiro Matsumoto's inspection, it was determined that it was the radio station of the military command.

"Mr. Liu, you are familiar with the password of the military commander, and you are a cryptographic expert, so I will ask you for this matter." Masahiro Matsumoto bowed to Liu Jinghua, his face full of hypocritical politeness.

"No problem, I'll do my best to crack this code." Liu Jinghua said firmly.

From this day on, Liu Jinghua stayed in the gendarmerie detachment every time he ate and lived, and he only slept three or four hours a day, and the rest of the time, he threw himself on the military commander's code detection.

When Lu Chengzhou learned that the entire telecommunications room was all cooperating with Liu Jinghua's cracking, he was secretly amused.

In terms of acting skills, Liu Jinghua is really not inferior to him at all.

After "struggling" for a week, Liu Jinghua finally succeeded in cracking the code of the military command.

"Mr. Matsumoto, it's broken!" Liu Jinghua's tired eyes showed excitement.

In order to make himself tired, he could only do the things of the original month again.

Sleeping three or four hours a day and doing a lot of calculations in order to make yourself look haggard.

"Really?" Masahiro Matsumoto has also been following Liu Jinghua's progress.

He is also a telecommunications expert and is very satisfied with Liu Jinghua's work.

Every day, Liu Jinghua does a lot of work.

"All the telegrams of the last week have been broken, please take a look at Mr. Matsumoto." Liu Jinghua said proudly.

The military commander specially left this wavelength and call sign, not just to let him make meritorious contributions in front of the Japanese.

However, after reading all the telegrams, Liu Jinghua understood that matches not only made him meritorious, but also had more profound meaning.

In the last ten days, every two days, Haigu Station will contact the headquarters.

Although the call sign is the same, the payment has become "fire".

This "fire" means both a flame and a match.

And the content of the telegram, in addition to reporting ordinary information about Haigu, also talked about the military police detachment.

For example, the organizational structure of the third intelligence room was introduced, as well as the residence of Yang Yushan and Chen Shugong: No. 5 Oxford Villa.

Since Shi Hongxia's death, Yang Yushan and Chen Shugong have lived together openly.

Masahiro Matsumoto knew that these telegrams were very important after just one glance, and immediately sent them to Ryoichi Nakayama's office.

"It seems that the military commander is in Haigu, and he is indeed doing nothing." Nakayama Ryoichi looked at the first few telegrams of the military command, except for some ordinary market information, most of the information was excerpted from local newspapers.

Only the military commander can deceive himself to such an extent.

However, when Ryoichi Nakayama saw Oxford Villa 5, his eyes narrowed into a line all of a sudden.

"How can it be!" Ryoichi Nakayama slapped the table angrily, among these information, the most important one turned out to be the intelligence of the military police detachment.

"Go down, it's really gratifying that the telecommunications room can crack the code of the military command this time." Ryoichi Nakayama was taken aback when he saw Masahiro Matsumoto and Liu Jinghua, and knew that he was scaring them.

Subsequently, Ryoichi Nakayama called Chen Shugong to his office and showed him the telegrams.

"This is a telegram from Haigu Station?" Chen Shugong only read one copy and immediately cried out in surprise.

"You'll read it all." Ryoichi Nakayama said lightly.

"It can't be!" Chen Shugong soon saw the telegram about himself, the military commander was very familiar with the third intelligence room, and also mentioned that he lived in No. 5 Oxford Villa.

If this telegram is seen by Yang Yushan, I am afraid she will not dare to go back tonight.

"The screening operation of the third intelligence room must be carried out immediately." Ryoichi Nakayama said with a deep groan.

"Yes, we're already working on it." Chen Shugong said slowly.

He had never wanted to start this screening operation, and these men had come with him from North China.

If the people below knew that Chen Shugong was suspicious of them, they would definitely be very chilled.

If his subordinates have an opinion about him, it won't be long before everyone will rebel and leave.

The next night, after Lu Chengzhou arrived at the gendarmerie detachment, he was notified to go to the large conference room for a meeting.

The meeting was attended by deputies, in addition to the heads of various departments.

The three squad leaders of the Third Intelligence Room also attended the meeting as observers.

"Lao Jin, do you know the content of the meeting?" Before Lu Chengzhou met Jin Timing, he received a notice.

In private, he usually calls Jin Timing "Instructor Jin".

But in public, it is generally called "old gold".

"I don't know." Jin Timing shook his head.

Jin Timing didn't know why he had a meeting, but Lu Chengzhou saw that several squad leaders from the third intelligence room had arrived, and his heart was already like a mirror.

Sure enough, after Ryoichi Nakayama arrived in the conference room, he quickly announced an action:

"Ladies and gentlemen, according to reliable sources, Zeng Hong, the head of the intelligence team of Haigu Station, will appear in Victoria Park tomorrow. This time, we must not let her go again. Ryoichi Nakayama's gaze slowly swept over the faces of everyone in the conference room.

"We can be in charge of the arrest." Lu Chengzhou immediately raised his hand and said loudly.

"Director Lu, this kind of thing, don't join in the fun in one room, right?" Yang Yushan turned her head, glanced at Lu Chengzhou, and said lightly.

"How can this be fun to eat, our one room is indeed not as good as three rooms. But one more person, one more strength. Lu Chengzhou said.

"Victoria's situation is more complicated, and this mission will be handed over to the third intelligence room." Ryoichi Nakayama said suddenly.

This screening action was originally proposed by Jin Timing, and Lu Chengzhou knew it well, and the reason why he was the first to raise his hand was probably to be more real.
