"In order to prevent leakage, each communication group can only master one set of passwords...... Only Chen Haoqiu has the original book, and after changing the password, he must also confirm it with the headquarters...... The confirmed verification instructions are also known only to Chen Haoqiu......"

"So if the radio station in Shanghai wants to change the password, Chen Haoqiu must be there?" Chen Zuyan asked suspiciously, "What's the use of Fang Buwei doing this?" ”

Ma Chunfeng pondered for a moment, "It may be that Fang Buwei wants to confirm Chen Haoqiu's specific location through the radio......"

If Fang wasn't there, he would definitely be scared into a cold sweat.

Fang Buwei really planned like this, and he didn't think about hiding it from Gu Zhenlong and the others, but even thought of an excuse on how to make the past.

When he planned to use this method, he thought that someone in Nanjing would definitely think of this, but he didn't expect it to be so soon.

"Joke!" Gu Zhenlong sneered, "Is the entire Shanghai City not opened for the family?" ”

In this era, there is no such thing as a radio direction finder, and even Britain and Germany, which have the most developed wireless intelligence business, can only use the mode of zonal blackouts to reconnoiter enemy radio stations.

"When the communication channel is established again, ask him!" Chen Zuyan confessed.

Ma Chunfeng nodded.

He was also very puzzled.

Before Fang Buwei left, he not only brought two code books, but also asked for the highest-level message instructions from him on behalf of the secret service.

At that time, Fang Buwei just said that after he arrived in Shanghai, he might send a report to Chen Haoqiu in the name of Ma Chunfeng.

Fang Buwei did send it, but the first telegram he sent asked Chen Haoqiu to change the power code?

Not to mention that Gu Zhenlong and Chen Zuyan didn't believe it, even Ma Chunfeng didn't believe it, so he couldn't use the radio to detect Chen Haoqiu's specific whereabouts.

……

Li Dingan drove the car, and Chen Haoqiu sat in the co-pilot, rushing to the city government.

They had just returned from the river.

The four team members were missing for two days, and when they were found, they turned out to be four corpses?

The person was killed with a gun before being thrown into the Huangpu River.

This is something that has never happened since the establishment of the station in Shanghai. ‘

Chen Haoqiu and Yang Dingan's faces were not ordinarily ugly.

"It's really eventful...... Yang Dingan let out a heavy breath, "Why did the headquarters suddenly let me change the password?" ”

"I don't know yet!" Chen Haoqiu replied with a gloomy face, "The director didn't say anything, he just asked the previous set of password books to be discarded on the spot......"

"Could it be that something is wrong with the headquarters?" Yang Ding'an said suspiciously.

"Not necessarily!" Chen Haoqiu said, "In addition to us, there must be other stations that are also using this set of passwords, maybe there is a problem in these places......

After receiving the report from his subordinates, Chen Haoqiu immediately thought of Tianjin Station, which had just had an accident.

I don't know if it's bad luck, in less than half a year, the two stationmasters in Tianjin have accidents. One went to prison, or indefinitely, and the other died mysteriously, and the final result turned out to be suicide?

Chen Haoqiu even suspected that it was an insider's hand.

But no matter how doubtful he was, Chen Haoqiu was just thinking about it. The headquarters has already sent a telegram to prove that Ma Chunfeng also recognizes this.

But if it's not the truth, I don't know.

Chen Haoqiu pondered for a few seconds, and then explained to Yang Dingan: "Start the temporary radio station!" ”

If there is a problem with the headquarters, the location of the two fixed radio stations in Shanghai Station will also be exposed.

"Where?" Yang Dingan asked.

"Let Yang Hu find a place!" Chen Haoqiu said.

……

After sending the order to change the password of the Shanghai station, Fang Buwei asked the dispatcher to continue to listen.

After waiting for more than an hour, the radio received a signal confirmed by Chen Haoqiu.

It seems that Chen Haoqiu is not close to the position of the radio station.

Fang Buwei's heart moved, and opened the system.

When he saw the specific location of the signal source, Fang Buwei almost stared out his eyes.

It's not the one from the city government, and this radio station is less than two kilometers away from here in a straight line?

Fang Buwei knew that Chen Haoqiu had three radio stations, one in the Shanghai Municipal Government, one in Nanshi, and the other was a mobile radio station.

The mobile radio station is too troublesome to set up, and it is extremely unsafe, so he didn't think that even if Chen Haoqiu didn't use the municipal government, he would also use the south city, but he didn't expect that Chen Haoqiu would use the mobile radio station, and it was so close to him?

How can this make yourself round after you go back?

Fang Buwei took a deep breath.

Don't miss the opportunity, don't come back if you lose it, let's find Chen Haoqiu first.

He counted the time first.

"Wait for the three confirmation instructions from the Shanghai station to be sent before sending a signal to confirm receipt...... You must remember to add the command code of Director Ma at the end......

Two minutes later, the Shanghai station was electrified, and the message was as follows...... It has now been found that the bandits have fled to Kunshan, fled to Shanghai, and took a Buick brand black car, and the body was damaged...... Please search for ...... as soon as possible in Shanghai Station and all departments."

Fang Buwei deliberately suppressed this piece of information overnight, and used it now.

"It's five minutes in total...... Do you remember clearly? Fang Buwei asked sharply.

"Humble duty understands!" The two dispatchers cautiously answered.

The big men in the back almost put the guns on their heads, and the two dispatchers were not afraid.

"Watch them out!" Fang is not a finger for Ye Xingzhong.

……

Fang Buwei was not convinced, with Chen Haoqiu's temperament, he would definitely not hand over the message instructions that only he knew to his subordinates to send on his behalf.

Coupled with the location of the radio station, there is a ninety percent certainty that Chen Haoqiu is next to the radio station.

During the War of Resistance Against Japanese Aggression, more than 90 percent of the radio stations of the underground party under the military command were located in the French Concession, because even if the Japanese knew that there were anti-Japanese elements in them, they could not enter.

At best, it can only be assassination or kidnapping.

For Chen Haoqiu, there is no safer place in the whole of Shanghai.

This is also one of the reasons why Fang did not want to set up the radio station and headquarters in the French Concession.

Chen Haoqiu's confirmation instructions were sent three times in a row, with an interval of one minute between each time, and another minute passed after the dispatcher confirmed it in the name of Ma Chunfeng.

By the time he received the notification message to the Shanghai station, Fang Buwei had already found the exact location.

"Fuxingji?"

Fang Buwei was across the street, looking at the golden plaque on the second floor, and silently read a sentence.

At the door stood four big men in black clothes and black pants, with their shirts open and the handle of their guns on their waists exposed, and they looked like gang members.

The building was full of people and lively.

Fang Buwei walked through the street and approached the gate, and the sound in his ears became even more chaotic.

"Ding Li, Ding...... Boom...... Buy and leave...... "This is shaking the dice."

"It's mahjong......

"Your Majesty...... Nine...... Nine ...... "This is Pai Gow.

Gambling?

Chen Haoqiu set up the radio station in this kind of place?
