77, still can't find the way of code breaking

After he finished speaking, he left the ward seemingly sensibly and closed the door.

At this time, when Gui Longhai and Qiao Yanfang looked back at Wang Changchun, they both realized that his mood had changed.

He stopped trembling, he actually closed his eyes, looking like he was waiting to be beaten!

Gui Longhai looked at Wang Changchun and knew that this was all he could do today. He could only end it as soon as possible and prepare for the next time.

He turned back and stared at Qiao Yanfang and said loudly: "Team leader Qiao, you are still here, I can't ask you anything! You all get out! Get out! Don't stay here anymore!"

As he said that, he pushed Qiao Yanfang.

Qiao Yanfang naturally understood what he meant, and knew that there was no point in asking further!

She grabbed the chair, pushed it down hard, turned around and left the ward. Qiang Hu also followed her.

Gui Longhai took a breath. Although he had huge doubts about Geng Jizhi in his heart, he still couldn't relax about Wang Changchun. Maybe he still had a chance to ask something.

He stared at Wang Changchun and said softly: "Secretary Wang, think about it, the city government has lost so many important files, no one will let it go! Right? This case will be solved sooner or later, it will definitely be solved! I think

You must understand this! If you have any trouble, it's better to solve it as soon as possible! I'm here for your own good!"

He stared at Wang Changchun. This guy had his eyes closed tightly, motionless as if dead.

He thought for a while and then said: "Secretary Wang, my ghost detective has taken over this case. I tell you, within two or three days, I will definitely investigate it! Secretary Wang, if you don't talk about it now, it doesn't matter. You can still

You can think about it again. If you want to say anything to me within two or three days, just call me. I guarantee that nothing will happen to you! Think about it again. Remember, I will only give you two or three days.

You have enough time to think about it! Secretary Wang, just take care of yourself!"

Gui Longhai deliberately emphasized his last words, and then observed his reaction again.

But Wang Changchun still didn't move, his eyes closed like a dead dog.

He understood that today's interview was completely ruined by Geng Jizhi! He turned around and left the ward, slamming the door shut.

Gui Longhai came out of the ward and saw Qiao Yanfang and Qiang Hu standing outside the door. He waved to them, turned around and walked towards the end of the corridor.

Qiao Yanfang understood that Gui Longhai's last effort was unsuccessful. It seemed that this was the only way to go today. She had no choice but to follow him.

They stopped at the end of the corridor and looked at the door of the ward from a distance.

But they waited for a while, and Geng Jizhi never appeared again.

Qiao Yanfang said coldly: "Chief Gui, do you want this person?"

Gui Longhai understood as soon as he heard that she was referring to Geng Jizhi. Geng Jizhi's sudden appearance really surprised him. He didn't expect it at all, so he shook his head.

Qiao Yanfang sneered, curled her lips and said, "Mr. Ghost Detective, let me tell you! From the first day, I knew that he was not the only one who stole the files! Just replacing the two hundred volumes of files with white paper will

It takes a lot of effort! I have been waiting for the first person to show up! The day before yesterday, I dealt with him in the city hall and beat him half to death! I just wanted to wait for that person to show up! I called the Secretary-General today just to let him know

Someone in the city government knows that I’m coming to interrogate Wang Changchun! Humph! Geng Jizhi didn’t show up until now! Damn, it’s really timely!”

Gui Longhai looked at her in surprise.

Only now did he realize that this little girl is really not an ordinary shrewd person!

However, Geng Jizhi's sudden appearance, although it was considered progress in the file theft case, still put him in a difficult position.

Geng Jizhi is a popular figure in front of Mayor Yu! He can also speak in front of several chiefs of the city police station! This situation is a danger for him, a small policeman who has climbed up from the bottom!

He asked in a low voice: "Team Leader Qiao, what do you think about...that person?"

Qiao Yanfang sneered, stared at him and said, "Chief Gui, I want to investigate him carefully! Just wait and see!"

Gui Longhai glanced at her sideways, thinking to himself, she is just a tigress! Extremely vicious! Anyone who falls into her hands will have a bad end! How could Brother Xiao like such a tigress! No way!

possible!

He silently muttered in his heart, Miss Qiao, don't let me take the chance! I will give you some eye drops when I get the chance! It will prevent the good things in your heart from coming true!

He thought for a moment, the handsome brother Xiao and the beautiful Miss Liao were indeed a good match.

This morning, Xiao Ancheng finally had some leisure time. According to Chen Zifeng's arrangement, he was at home today to watch the radio station.

He still got up very early because the whole group was up and preparing to go out in a hurry.

The waiter from the street restaurant brought breakfast. They ate breakfast while listening to Qiao Yanfang assign tasks to everyone. Among them, she specially designated a group of people to monitor Geng Jizhi.

Chen Zifeng looked at her in surprise, "Xiao Qiao, why are you staring at him?"

Qiao Yanfang said: "Zifeng, think about it, who wants the city government's files the most! It's the damn Japanese! I'll send people to keep an eye on Geng Jizhi, and it's possible to find the Japanese!"

Chen Zifeng couldn't help but laugh, "If you arrange it this way, no one will go to the old beggar."

Qiao Yanfang said: "You can take one person with you and travel around the world."

Chen Zifeng said: "Zhabei Station needs to be monitored for another day. Forget it, I'll take someone to Zhabei Station. If we can't find any clues today, damn it, I won't keep an eye on him anymore."

Qiao Yanfang said: "Okay, let's do it. Everyone else should pay attention. When walking on the road, look for an old beggar sitting on the street. If any of you find it! That will be a great achievement! Understand.

No!"

The team members all grinned and said, "We found the old beggar. Is there any reward?"

Qiao Yanfang shouted: "Damn it, that's a huge reward! Don't miss it!"

Chen Zifeng thought for a while and decided that he could only arrange it this way, and said nothing more.

After breakfast, Xiao Ancheng sent everyone out, and then came back for breakfast. After that, he started cleaning.

These days, all the brothers in the group are working almost non-stop and have very little time to sleep. There is no time to tidy up the interior.

Yang Sanqiang was still lying on the floor sleeping soundly. He had not slept all day and night, and it was time to make up for it.

The clothes that the brothers usually wear when going out are scattered around the room. There are all kinds of suits and jackets, old and new shirts and sweatshirts, long and short shirts, and coarse cloth clothes worn by coolies.

Xiao Ancheng put all these clothes on hangers and hung them on a long bamboo pole. They looked colorful and spectacular, just like the costume room backstage in a theater.

Dozens of pairs of leather shoes, cloth shoes, rubber shoes, and even two pairs of long leather boots with spurs were piled under the wall. He also arranged them neatly.

He wiped the tables and chairs, mopped the floor, and dumped the garbage into the broken bamboo basket outside the door.

He sorted the weapons and ammunition in the cabinet and inspected upstairs and downstairs before finishing the cleaning work.

He washed his hands, returned to his small room, turned on the radio, and sat down at the table.

He took out a mimeographed "Summary of Practical Cryptography" from under his pillow and opened it to read.

This is a textbook issued by the telecommunications training class of the Hangzhou Police Academy. He has almost read it to pieces, and all the contents are in his mind.

Studying the compilation and deciphering of codes is his biggest worry at the moment.

Lao Long said to him: "We need an excellent code-breaking expert! This task is very important! We hope you can become such an expert!"

Lao Long also said: "I know this is difficult, very difficult. It's like drilling wood to make fire. If you study long enough, sooner or later you will succeed!"

However, he studied alone for more than a year and still could not find a way to decipher the code.

What he learned from the training class was all mentioned in this mimeographed booklet. What about permutations, substitutions, shifts; what about Hill cipher, Caesar cipher, Vigenère cipher, Vigenard

He has thoroughly studied passwords, frequency analysis methods, square matrix deciphering methods, etc., but he still hasn't figured out the way.

The reason is very simple. All of these have been studied by others and printed in this booklet. He has also learned them. Therefore, these methods are not secrets! Others will not use them again!

He believes that current users, especially Japanese, must have updated password compilation methods!

Xiao Ancheng has another difficulty in researching code deciphering. He does not have enough telegram traffic!

In the past, in the telecommunications department of Honggong Temple in Nanjing, there were seven or eight high-power radio stations at all times, which selectively intercepted some telegrams, focusing on those sent by the Japanese Ministry of Foreign Affairs, the Japanese Military Department, and the Japanese troops in Northeast and North China.

There are hundreds of thousands of telegrams in total, so the traffic is quite considerable.

The orientation and distance of most of these telegrams have been determined using direction finders, and it is even roughly known which department or unit some telegrams were sent from.

Such telegram traffic and accumulation are the indispensable basis for deciphering codes!

However, he has nothing now. He is actually looking for a needle in a haystack!

He once intercepted some messages at night, but soon found that they were of no use.

He couldn't determine the direction, so he couldn't determine the unit that sent the telegram. He didn't know whether it was a company or a bank. He couldn't tell whether it was the Japanese army or the Japanese Ministry of Foreign Affairs.

He can only give up. In short, studying code deciphering is his biggest problem at the moment!

At this time, he heard a "beep" sound coming from the earphones, and a set of telegrams flashed past. He waited quietly for two minutes, and the set of telegrams rang again. He confirmed that it was Lao Long who wanted to meet him.

He quickly replied with a set of telegrams.

He went upstairs and looked at Yang Sanqiang, who was still sleeping soundly. It was estimated that he would sleep for a while.

He turned around and went downstairs, pushed the broken bicycle out of the west wing, went out, got on the bicycle and left.

Xiao Ancheng soon arrived at Changbai Street, placed his bicycle outside the door of Yixiang Radio Repair Shop, and quietly entered.
