Zhang Luping met the girl wearing a dress when she accompanied her brother Zhang Weilin to dinner for three consecutive days. She was surprised that the girl wore three sets of very beautiful dresses in three days.

Today, Zhang Luping made a special observation. This girl went to the tailor shop diagonally opposite the hotel. Only then did she realize that this person was the daughter of a tailor's family!

In broad daylight, after Zhang Weilin went to work, Zhang Luping would either sleep in at home or go shopping for clothes or something with a small bag on her arm. She was indeed a little panicked at leisure.

Zhang Luping liked the skirt the girl was wearing very much, but she kept in mind that she was an underground worker, so she resisted the urge to go to the tailor shop.

On this day, Zhang Luping was really bored and couldn't hold it back. She decided to take a look.

Arriving at the tailor shop, Zhang Luping was surprised to find the girl cutting fabric.

When the girl saw Zhang Luping coming in, she felt happy in her heart: 'The boss is really omnipotent. She came to the store within three days.' However, she kept Yu Zecheng's advice in mind and was not overly enthusiastic, treating Zhang Luping as an ordinary girl.

Treat. She said: "Miss, are you here to customize clothes?"

Zhang Luping looked at Song Zulian carefully and said, "Did you make the clothes you are wearing yourself?"

"Yes! If you like it, I can make one for you. You can choose the material yourself." Song Zulian said with a smile.

Zhang Luping was very impressed by this girl. She didn't expect how this girl who didn't look particularly elegant could design such a beautiful and fashionable skirt! She wanted to know if this girl could do it. She said: "Your dress

How much does a set of skirts cost?”

Song Zulian said: "It's not expensive! Twenty-five yuan a set."

It’s not expensive! Most people can’t get so much money in a month. If three yuan is exchanged for one silver dollar, it’s equivalent to eight silver dollars, which is equivalent to more than two loads of grain. It can feed six or seven people in a month. However, Zhang Luping himself

Her family is rich, and besides, she has ample funds for her activities. In fact, many of her activity funds were secretly provided by Yu Zecheng. This money is like flowing back.

Zhang Luping said: "Then you can customize a set for me!"

Song Zulian took a soft ruler to measure Zhang Luping's body size. While measuring, she said: "Miss, you are not only beautiful, but you also have a good figure. You must be very beautiful in a dress!"

Song Zulian was half flattering and half telling the truth. Zhang Luping herself had the temperament of a young lady, and she was one of the best in appearance. In addition, she was well-informed and had been gilded in Yandu. That kind of comprehensive beauty was indeed incomparable to ordinary people.

After all, Zhang Luping is a nineteen-year-old girl, so she sounds very happy.

In this way, Zhang Luping and Song Zulian met.

Two days later, Zhang Luping came over to take the dress, and the two chatted casually again.

Soon, Zhang Luping found that when she had no place to play, she would come to the tailor shop to chat with Song Zulian. And she couldn't help ordering two more sets of skirts.

Gradually, Zhang Luping felt that Song Zulian was very attractive to her. She was slightly surprised. This alerted an underground worker! When she contacted her superiors, she reported the situation.

Yu Zecheng began to decipher the messages of Huang Dupin's spy team.

In fact, it can't be called deciphering. What is it called? It's called arrangement. He took out two original documents from the bureau headquarters and made technical modifications. One was the "Notice on Preventing Japanese Spy Activities in Chongqing", and this document

It mainly lists the activities of several Japanese espionage groups in Chongqing, which wakes up the counter-espionage agencies in Chongqing and should pay attention.

The other one is "About the Process of Detecting Japanese Spies Isamu Muto and Yun Muto". However, the writing is very thick and does not reveal much about the detection techniques. However, the document is very long.

Both of these documents are internal and classified. However, in Yu Zecheng's opinion, they are of little value. Therefore, he carried out technical processing to decipher the passwords in these two documents. For example, he set up three numbers repeated twice.

For a word phrase, a two-character phrase repeated three times is set. In addition, there are repeated phrases in the original text.

Yu Zecheng took out the two messages sent by the traitors that night and compared them. First, he distinguished the two messages.

Then he looked for the technical processing set up by Yu Zecheng in the message. He assumed that the traitor intelligence personnel did not disrupt the order of the message. He quickly found the content of the technical processing. Then he arranged it according to the order of technical processing.

In this way, Yu Zecheng set up a codebook. But is this codebook the traitor's codebook? This still needs to be verified.

Yu Zecheng took out more than 30 messages that were originally monitored, found the repeated codes in the message codes, and translated them.

Yu Zecheng spent three days and nights translating the two duplicated characters in more than 30 messages. Then he found several messages with one-third of the characters translated. There were five messages in total.

. Then find relatively dense characters among them, and then fill in the blank characters according to the connection between the characters to see if it is written.

After translating these five messages, Yu Zecheng was pleasantly surprised to find that at least four of them were written. Not only did they make sense, but they also had practical significance.

Yu Zecheng then filled in the blanks and wrote the message code in the new code book.

In this way, a new batch of characters was generated. He then filled in the new characters into the other twenty-seven messages, creating a batch of characters that could be filled in the blanks. The cycle continued, and finally, Yu Zecheng could no longer fill in the blanks in those messages.

. He just stopped!

At this time, Yu Zecheng deciphered 22 of the 32 messages.

At this point, Yu Zecheng has a codebook of more than 600 characters in his hand!

When Yu Zecheng came out of the office, it was already the fifth day!

During these five days, except for eating, drinking and having diarrhea, he never left the office. He was so sleepy that he took a nap on his desk. He couldn't leave because once he left this environment, all the messages and data that were filled in his brain would be forgotten.

Or lose it temporarily. In this way, his inspiration will be rejected.

After analysis and combing, Yu Zecheng found that most of these telegrams were transcribed documents. Some were from the city government, some from the police station, some from the Central Military Commission, and of course, some from the military commander. However, based on his analysis, these were only the minimum

Level confidential documents. Such documents cover a wide range of areas, and it is difficult to find out who leaked them from the document itself.

Yu Zecheng also needed the approval of his superiors for not arresting the traitor spies immediately. Otherwise, once Huang Dupin collected major confidential documents and sent them out, he would have to bear heavy responsibilities. However, Yu Zecheng did not want Lu Zongfang to know.

, and he didn’t want the two heads of the Operations Department to know. He was very worried that these people were eager for quick success and immediately arrested Huang Dupin.

Once Huang Dupin is unwilling to confess and goes offline, or other accidents occur, the spy team will be unable to crack it.
