The leak case had just been closed, and Yu Cheng came to report it. It seemed that Gu Zhengqi was urging the air strike case very urgently.

"Please come in!"

Soon, Yu Cheng quickly entered the office with laughter all the way.

"Saturday, I am lucky to learn from you again this time. I am so happy that I don't know what to do. I will report to you as soon as I receive the order!"

Yu Cheng has always been smooth in his work, talking to others and talking to ghosts, let alone being the tough character Ning Zhiheng. He is the one who deals with Ning Zhiheng the most in the Intelligence Department, and he is convinced from Ning Zhiheng from the bottom of his heart.

Ning Zhiheng also got up and came to Yu Cheng's side, and said with a smile: "Old Yu, I am not your chief official, so you don't have to be too polite. Let's call me Zhiheng!"

Although Ning Zhiheng's position is higher than Yu Cheng, the two have no affiliation. Yu Cheng does not need to respect the title of Du Se, but Yu Cheng is so sophisticated that he dares to call him Zhi Heng. He waved his hand and said, "Don't be a little bit casual, don't scare me!"

After saying that, Ning Zhiheng showed an exaggerated expression on his face, and he was just polite. He had hit Cheng a lot and gave him some warnings several times. Now it seems that the effect is really good.

"Haha, then let's do it! Come on, let's sit down and talk."

Ning Zhiheng sat down on the side and said bluntly: "I heard that the air strike was the responsibility of you at the beginning. How about it? After so much trouble, have you found a suspicious target?"

When talking about the air strike, Yu Cheng put the thick file in his hand on the table, his face suddenly became frustrated, and he said with a wry smile: "There is no progress at all. I'll introduce you to the specific situation."

Afterwards, Yu Cheng carefully described the specific situation of the air strike that occurred a month ago, and then continued: "At that time, we judged that this was a purposeful attack by the Japanese based on the situation on the scene. The Japanese found out that Yi Dong was claustrophobic, and they might even know that he had just accepted a new task of deciphering Japanese military codes, so he couldn't wait to start with Yi Dong."

After listening to Yu Cheng's narration, Ning Zhiheng thought for a while and said, "You are very accurate in analyzing. The reason why the Japanese used air raids to kill Yi Dong was to make us think that this was just an accident, to cover up the fact that there was a traitor within us and to cover up this traitor."

Yu Cheng nodded quickly and said, "It is precisely this truth, but it is more obvious. So the bureau commander ordered us to conduct an internal investigation, but the target has never been determined. There are many people who know that Yi Dong is claustrophobic, because every time the Japanese air strike, everyone hides in a nearby air raid shelter. Only Yi Dong is not there, so they will inevitably inquire with each other, so his colleagues and neighbors may know about this, and the scope is difficult to determine.

However, only the core members of their deciphering team knew that Yi Dong took over the deciphering Japanese military codes knew that the deciphering team's work was very special and secret, and they did not deal with other departments at ordinary times. Moreover, we emphasized the confidentiality regulations for the deciphering work, and must not be disclosed to the outside world. There should be no possibility of intelligence leakage, so we focused our target among the eighteen members of the deciphering team."

"There are eighteen members in total?"

"Yes, with Yi Dong, there are 19 people, and there are a total of 103 staff members in the decipher room, but most of them are auxiliary service personnel, such as cleaning guards, but there are only 19 core members, all of whom are the best decipher experts and mathematicians in the country. These people are the key to doubting the target.

The bureau commander cannot alarm the snake, so that the Japanese and traitors think that we really believe that Yi Dong's death was an accident, and we really cannot torture these experts. These are all gold and silver treasures, which really hurt people. The password work depends entirely on the brain. If you don't work hard in the future, you will not be able to do your job. So we have been investigating the situation around them, but there are a lot of things we have investigated, and we can't see that. I'm just waiting for you to take over at the seat."

Ning Zhiheng opened the file and a thick stack of investigation reports inside. He couldn't help but sigh, "It's time to stay up all night tonight."

"Old Yu, look, I'm still dealing with the beginning and end of the leak case. I'll have to go through the information you brought, and I can't find any clues in a while. In this way, you go back first, I'll get familiar with the situation first. I'll call you tomorrow, let's go to the deciphering room to take a look, and then visit Yi Dong's family."

Yu Cheng also saw a pile of documents on Ning Zhiheng’s desk, and quickly nodded and agreed, stood up and said goodbye.

Ning Zhiheng sent Yu Cheng away, looked back at the documents and materials in the room, and couldn't help but sigh and began to handle official business.

That night, Ning Zhiheng didn't even go back home. He looked through the information until late at night and dealt with it all night on the sofa in the office. Early the next morning, he got up and washed up briefly, then called Yu Cheng, then left the second place and rushed to the headquarters.

At the gate of the headquarters, Yu Cheng had been waiting there for a long time. When he saw Ning Zhiheng coming, he quickly came up to meet him.

"There is still a long way to go to the location of the deciphering room. I will lead you."

Yu Cheng got into Ning Zhiheng's car, and the vehicle quickly drove east for a distance, stopped at the gate of a courtyard, and then got off.

Yu Cheng pointed to the gate and said, "This is the deciphering room. He was specially separated from other departments of the headquarters, just because he was afraid of attracting attention. He was also very strict in management and was very cautious. All the staff here could not bring out a piece of paper, otherwise they would be engaged in military law."

Ning Zhiheng looked at the door, and there was no word bare.

Yu Cheng smiled and said, "The deciphering room department is not afraid to have a sign. I heard that there is a deciphering department in the United States called the 'black room', so everyone also called it the 'black room'. In short, the confidentiality level is the highest."

Speaking of this, he sighed again: "Who knows that there is an insider!"

Ning Zhiheng asked his guards to stay at the door. He and Yu Cheng entered the door. There was a team of guards guarding the door. The officer on duty had already received the notice and had checked the documents of the two people before he let them go.

After Ning Zhiheng entered the courtyard, he looked around and found that it was no different from ordinary large houses. It was probably occupied by the residences of large houses, but the atmosphere inside was very depressing and quiet. There were also guards in the corridors and yards. Occasionally, someone walked by, and he was also in a hurry. He ignored Ning Zhiheng and the other two.

Yu Cheng was obviously used to it, so he took Ning Zhiheng into the inner courtyard, pointed to several rooms and said, "These rooms are the studios of the deciphering team, the radio reception room, the monitoring room, the archive room, etc. The people inside are working, and we can't get in now."

Ning Zhiheng frowned and said, "Didn't it mean that the deciphering work is not progressing at all? Then what are they doing?"

Yu Cheng shook his head, shook his shoulders and said, "Only one of them knows that these people are very arrogant. If you ask them a little bit of knowledge, you will be impatient and never explain. I still have to smile with you."

At this moment, a middle-aged man quickly came over, stretched out his hands a few steps away, and said with a smile: "Director Ning, I heard that it was you who came to inspect, so I rushed over immediately. It was really negligent!"

Ning Zhiheng smiled and reached out to hold it with him, and said with a smile: "Old Bian, Ning is coming uninvited, I'm going to disturb me!"

The person who came was Ning Zhiheng's acquaintance, Bian Deshou, the head of the lieutenant colonel of the Telecommunications Department. He was the leader of the major when he was in Nanjing a few years ago. He had contacted Ning Zhiheng several times and had assisted him in solving the cheongsam case and the radio wave case. The two of them were considered old friends.

Ning Zhiheng knew when he was looking up the information last night that Bian Deshou is currently the director of the deciphering room. He does not know how to decipher the code and is only responsible for cooperating with the work of these experts in the deciphering room, similar to the position of the butler.

Bian Deshou naturally did not dare to be negligent about Ning Zhiheng, the senior military commander. He looked at Yu Cheng beside him and knew why the two of them came. He quickly smiled and said, "Director Ning, if you have any questions, please tell me, I will cooperate!"

Ning Zhiheng pointed to the studio and said, "Can I go in and take a look?"

Bian Deshou nodded quickly and said, "No problem, I'll make arrangements right away."

Yu Cheng, who was beside him, said angrily: "Old Bian, I have been here so many times. If you want to go in and take a look, you will just stretch your face and say no, why is it so happy this time?"

But Bian Deshou did not answer at all, pretended not to hear, turned around to arrange the matter, and came back quickly, asking Ning Zhiheng to come over, and Yu Cheng also quickly followed.

Bian Deshou looked at Yu Cheng, opened his mouth, and finally said nothing. Yu Cheng pretended not to see anything, and followed Ning Zhiheng into the studio.

The workrooms in these places are interconnected and there is a huge space inside. The first workroom is equipped with large radio reception equipment. Eight radio operators are carefully receiving and recording various radio signals with headphones, and the sound of the sound is endless.

The second room had a long square table with various data materials on it. Eight or nine telecommunications experts were calculating, but no one looked up at the three of them.

Ning Zhiheng stepped forward and looked at the materials on the table. An expert immediately reached out to block the materials and gathered them together. He looked at Ning Zhiheng with an scrutiny, as if he were looking at a thief. If it weren't for Bian Deshou standing next to Ning Zhiheng, he would probably have called the guard.

Ning Zhiheng had no choice but to turn around and look at another man in his thirties on the side. The man was filling in a set of numbers into a form, looking up at Ning Zhiheng, smiling slightly, and showing a friendly expression.

Ning Zhiheng also quickly smiled and reached out to signal, and took a telegram from the table, which was all common.

Ning Zhiheng was just a little curious about the arrangement of Arabic numerals, but he knew nothing about deciphering the password. He looked around and put it down casually.

I turned around and looked at other experts, silently corresponded them one by one with the people I read in my materials, and then I entered the third room, which were all desks. It seemed that the office space was quite tight. Each person had only one desk, and everyone shared the same room. There were also several experts in this room calculating data. From time to time, a radio operator submitted a new message.
