After Fang Buwei set out, Ma Chunfeng sent a secret message to Chen Haoqiu, warning Chen Haoqiu about keeping the secret. Chen Haoqiu didn't know the whole story, but knew the severity and did not dare to reminisce with Fang Buwei. He arranged personnel every time and began to secretly investigate the clues of Eio Fukuda.

The look has been made, and the rest is how to contact Hu Yueming.

After Chen Haoqiu left, Fang Buwei went to the Commercial Press and transferred the entire bookstore before he moved a set of "Yongle Encyclopedia" and started to translate.

Seeing that the pages were turned quickly, no one in the bookstore could understand what Fang Buwei was doing?

Count pages?

Isn't it enough to just look at the number of the foot?

Fang Buwei wanted to set up a set of contact secret codes alone and compile a set of secret codes that do not repeat the loop at one time.

To give the simplest example, for example, the code name of the first character in the password is 1234, which represents the fourth character on the third line of the second page of the first volume. After using it once, the word at this position will no longer be used.

Next time you want to use this word in the information, you will search on another line, another page or even another book, and use temporary algorithms and formulas to generate another encoding.

As long as you don’t know the meaning of the first set of codes in the message, that is, the first word of the message starts from which page or line, even if the enemy holds the password in his hand, he cannot decipher the specific content of the message.

This is a solution that Fang Buwei asked Chen Xinran and Qi Zhenjiang, and then came up with the idea of ​​the electronic banking commands of later generations.

The biggest feature of this coding is randomness.

The position of the starting word is temporary, the algorithm is temporary, and the formula is temporary, and even the codebook can be replaced at any time...

The disadvantage is that it is cumbersome. If the message sent or received is a little longer, a person cannot translate it instantly. Moreover, every time you translate, you must hold the password book.

But Fang Buwei has no such difficulties at all.

He just asked the system to scan it.

When it was getting dark, Fang Buwei left the bookstore.

When he returned to the residence arranged by Chen Haoqiu for him, Chang Buwei fell asleep until he was about to 1:00 a.m. when he turned up and sat up.

It is suspected that the radio station that sent a telegram to Lin Zhicheng yesterday has started working.

The wavelength is 15 meters, the frequency of use is 6190... The radio station receiving the telegram is suspected to be located near Nanjing...

Eighty-mostly, Hu Yueming and Lin Zhicheng were sending telegrams.

After breaking the position for a while, Fang Buwei realized that he was not very far away from him.

He is not surprised at all.

Ninety-nine percent of all the radio stations hidden in Shanghai are hidden in the French Concession.

Because of the Public and Directors Bureau and the Three Daxiangs, the French Concession is the safest lurking area in the entire Shanghai, no doubt about it.

After listening to the movement outside, while the army and the three guards were sleeping in scent, Fang Buwei opened the window lightly and quietly went downstairs.

When Fang Buwei arrived at Huaishui Lan, the radio station was sending a second message.

The person who sends the telegram is very careful. The sending time for each message will not exceed five minutes, and then wait at least twenty minutes before sending the next one.

Fang Buwei took a look from afar.

It is a small brick-shaped building with three floors. At first glance, the three floors are covered with lights, but Fang Buwei can still recognize that the lights are on in the room on the third floor, and the windows should be covered with quilts.

Fang Buwei leaned over slowly. When he passed under the window on the first floor, he deliberately paused for a minute and stood there lit a cigarette.

Seeing that there was a person standing outside the window and not leaving, the two guards guarding the room on the first floor looked at each other, barefoot and walked to the window lightly, looking at Fang Buwei outside.

Fang Buwei vomited a cigarette ring and gently curled the corner of his mouth.

It seems that's right, it's here.

He sucked two bites with the cigarette roll, then drove forward again.

Two or three minutes later, Fang Buwei walked around the back of the building again.

There is also an alley behind it, not wide, only more than one meter.

Fang Buwei deliberately took a little further away, climbed up to the roof of a small building along the corner of the wall, and observed quietly.

There was no one on the roof nearby, including the one with the radio station hidden.

The telegram disappeared, and the second telegram must have been sent.

Fang Buwei moved to the small building where the radio was located with slightest move.

When Fang Buwei got up to the roof of the building, a subtle "drip" sound came from his ears.

This is not the sound of sending a newspaper. It should be that the radio station is turned off and the telephone code is being collected using equipment such as radio.

Fang Buwei guessed that Hu Yueming should be using a high-power radio station, which was afraid of affecting the voltage around the finance community, so he did not dare to send reports for a long time, and he used a low-power radio when collecting reports.

Fang Buwei is in a large shape and is tightly attached to the roof.

A few minutes later, the sound of the radio disappeared, and the sound of writing came again.

This is translating the code.

Two "wow" sounds, someone was shaking the paper, and Fang Buwei heard another man talking: "Section Chief, look!"

Fang Buwei was happy.

Sure enough, it didn't come in vain.

The only section chief mentioned by the reporter was Hu Yueming.

The four section chiefs and the other three Long March, in the Soviet area, can only be called "section chiefs" by Mr. Hu, who has just been appointed as the person in charge.

After reading the telegram, Hu Yueming wrote a few words with a pencil brush, and handed them over to the sender: "Send it as you like this!"

Fang Buwei let out a light breath.

He had never seen Hu Yueming, so he could only defend himself through his voice. The next time he heard him speak, he could know which one it was.

After about half an hour, Hu Yueming pointed out the sender to hide the radio station. Fang Buwei heard that he was packing his things, and it seemed that he was leaving.

It’s best to be able to leave, so there is no need to stay on the roof for a night.

Fang Buwei left the roof of the building lightly and walked around to the distance and went downstairs.

He had just gotten down to the alley and heard a light sound coming from behind him. He heard the noise as if he had pulled out a rickshaw from the yard.

Fang Buwei took two steps quickly and went straight to meet him.

The rickshaw driver vaguely saw a figure coming out of the alley entrance and was shaking towards this side.

"It's so late, where did you come from?" The rickshaw driver subconsciously slowed down.

This is a double-slave car, one guard pulls the car, and the other guard sits next to Hu Yueming...

Hearing the reminder from his companions, the guards in the car secretly held the pistol.

"Don't stop!" Hu Yueming reminded.

The coachman nodded softly and slowly met Fang Buwei.

Fang Buwei was filled with alcohol, and he staggered and held a bottle of wine that was about to come to the bottom.
