Ning Zhiheng didn't say anything more, walked through several rooms, and also looked at all the members of the deciphering team before leaving the studio.

Yu Cheng followed him in a confused manner without knowing Ning Zhiheng's intentions.

Ning Zhiheng turned to Bian Deshou and asked, "Old Bian, there are many of these experts. Are they in their usual working conditions like this? It seems to be very busy."

Bian Deshou nodded and said, "It's the same in normal times, but don't look at their bad tempers and don't like to pay attention to others. But the work attitude is unsafe. Sometimes I work day and night."

Yu Cheng said disapprovingly: "What's the use of this? Our Military Affairs Bureau has invested so much in recent years, but it has not achieved any results."

Bian Deshou didn't like to hear this sentence, and defended him: "It's hard to say about password decryption. Sometimes a flash of inspiration can compare to the accumulation of several years. You don't understand what you say to you!"

Ning Zhiheng waved his hand and interrupted them, then asked: "How was Yi Dong's work performance when he was here?"

"It's impossible to say that Yi Dong is a workaholic. He is not only an excellent mathematician, but also a Japanese student who is proficient in Japanese. It can be said that most of his work results are done by him and he is very active in his work. Usually he always comes first and leaves the last one. Alas! What a pity..."

Bian Deshou shook his head and sighed. For the entire deciphering team, Yi Dong's death was an irreparable loss. Over the past month, the work of the deciphering team has almost stagnated.

Ning Zhiheng continued, "I want to ask, do Yi Dong have any hobbies in daily life?"

Bian Deshou said: "He has no hobbies. He is a boring person and only likes work. However, he is very kind and has a little weak temperament. He is a very introverted person!"

Ning Zhiheng nodded. These were roughly the same materials as those given to him by Yu Cheng. He also focused on Yi Dong's materials last night, sorted out his ideas, and then asked: "Will he bring his work home?"

Bian Deshou was stunned and shook his head and said, "No, no, they can't take back every page of paper here. Their deciphering work can only be carried out in the deciphering room. Even if they decipher at home, even a piece of verification paper or form must be destroyed and must not be spread. This happened before and was severely punished, and they no longer worked at home. Even if they worked overtime here, they would not take their work home."

Ning Zhiheng pondered for a moment, then said: "I read the case information at that time. On the day of the air strike, eight of these experts were still working in the deciphering room. The remaining eleven experts, including Yi Dong, were resting at home. Why is that?"

Bian Deshou explained: "It was the 16th that day. The rule in the deciphering room is to rest on sixth. On the sixth, sixth, and twenty-sixth of each month, these three days are rest days, so most experts are at home, and eight experts are working overtime in the deciphering room.

Because they have a division of labor in their hands, some are responsible for calculations, some are responsible for sorting, and some are responsible for analyzing. The work progress is different, so the work is relatively free and there is no need to tie them together. We don’t stop some people who are willing to work overtime."

"So does Yi Dong like to work overtime?"

Bian Deshou was stunned and thought for a while and replied: "Yi Dong usually has no business hobbies. He often works in the deciphering room on his rest days, especially before being killed. He had almost no rest. Later, he finally successfully deciphered several Japanese passwords. The bureau chief rewarded him greatly and ordered him to strike while the iron is hot and to speed up deciphering the Japanese military passwords. Therefore, he is very motivated and rarely rests on his rest days."

"Then why didn't you come to work overtime that day?"

Bian Deshou and Yu Cheng looked at each other, and Yu Cheng said hesitantly: "After all, the 16th is a rest day. Even if Yi Dong doesn't come, it's not an exaggeration to work for a long time and rest for an occasional day. Don't most experts also rest at home?"

Ning Zhiheng shook his head, ignored it, turned around and ordered: "Let's go to the place where Yidong was killed to take a look."

Yu Cheng agreed and the two went out together. Bian Deshou thought about it and chased after him. He asked with a smile: "Director Ning, I don't know if it's not convenient for us to go and have a look together."

Yu Cheng seized the opportunity at this time and said with a stern face: "Old Bian, you have the final say in this deciphering room. After this, it is our business. We will find the secret of the case. You should not participate."

These days, Bian Deshou has been a little impatient with Cheng's visit to investigate many times, so he always uses confidentiality as an excuse to criticize Yu Cheng. Now Yu Cheng seizes the opportunity and makes Bian Deshou fall in love with just one sentence.

Bian Deshou rolled his eyes angrily, turned around and was about to leave. Ning Zhiheng quickly reached out to stop him and jokingly said, "Old Bian, Lao Bian, Lao Yu is joking with you, are you still calculating? Let's take a look together. There are many things I want you to adviser."

Ning Zhiheng's words made Bian Deshou very proud. He looked at Yu Cheng with quite disdain, and then he got into the car with Ning Zhiheng. The group quickly drove for a block and arrived in front of a ruin and stopped.

Ning Zhiheng and others got out of the car and looked around. They saw that the nearby buildings also collapsed, with bricks and tiles everywhere, and the explosion was very thorough. Obviously, the bombing was very dense at that time. He asked, "Is this Yi Dong's original residence?"

"Yes, it's here!" Yu Cheng nodded and said, he took a few steps forward and drew a semicircle with his hands. "I haven't moved anything here before, and I keep the appearance of an explosion. In the past two days, the people in the city hall have always urged us to restore this residence as soon as possible."

Yu Cheng was serious and careful in doing things, and the on-site protection was also very good. Ning Zhiheng looked around. Yu Cheng followed behind and pointed to a vacant land and said, "This is an vacant land in front of Yi Dong's residence. The bombing sign belt was found here."

Ning Zhiheng nodded, started walking around again, turned to Cheng and asked, "Where is Yi Dong's family now?"

Yu Cheng looked back at Bian Deshou. Yi Dong was affiliated with the Telecommunications Office, and the arrangements of Yi Dong's family should be under his jurisdiction.

Bian Deshou quickly replied: "Just not far ahead, the bureau chief specifically told him to treat Yi Dong's family well, so he paid a high pension and distributed an independent courtyard."

Ning Zhiheng nodded. The director was very particular about doing things, and he finally deserved Yi Dong, a meritorious minister.

After staying at the scene for a long time, Ning Zhiheng came to the open space and walked around, lowering his head to think about something. Bian Deshou and Yu Cheng were standing by, waiting quietly.

After a long time, Ning Zhiheng looked up at them and began to analyze: "Last night, I looked at the materials you investigated before, and I was a little suspicious that the Japanese had taken great pains to attack Yi Dong and did not hesitate to mobilize bombers to launch a raid. Such a big move is not easy to prepare.

After doing so much preparation and investing so much energy, they will never allow this task to fail easily, so they must ensure the success rate to the maximum extent. First of all, and the most difficult point, we must confirm Yi Dong's position.

Let’s analyze it from the beginning that Yi Dong’s whereabouts are easy to grasp. He has no preferences. He usually only works at home or in two locations, such as deciphering rooms. If the Japanese want to accurately attack Yi Dong, they can only start from these two locations.

First, bombing in the deciphering room is difficult. Bombers drop bombs at high altitudes, and the accuracy is very low. Even for low altitude bombing, ground guidance is required, that is, bombing signs are required, otherwise they will not be able to accurately bomb the target.

The deciphering room is under a strong guard and belongs to the military control area. There are guards around it. Even before the bombing, it is difficult for Japanese spies to arrange signs nearby, and it is difficult for them to escape afterwards. Without the ground signs, bombing in the deciphering room has an extremely low success rate.

Then I can only bombard the house of Yidong. I have seen the surrounding situation. The management here is very lax and there is no guard arrangement. It is no different from the ordinary family area. It is coincidentally. There is this open space in front of Yidong's residence. Before the bombing, when everyone is hiding in the air-raid shelter, as long as they are quick to arrange bombing signs here, and there is no need to worry about evacuation, so the Japanese chose to take action at his residence.

The bombing location has been determined, and now we need to determine Yi Dong's location. Although it was a rest day that day, how did the Japanese determine that Yi Dong would definitely rest at home instead of working in the deciphering room?

You should know that Yi Dong often works overtime on holidays, and even if he doesn’t work overtime, he may go out shopping and relax with his family. How did they make sure Yi Dong must be at home?

Japanese bombers took off from Hankou and came over Chongqing. The whole journey took more than 700 kilometers, which took an hour and a half. Even if a traitor confirmed that Yi Dong did not work overtime at home or went out for a trip on that day, and then sent a report to Hankou, Wuhan. Japanese bombers received the order to set off. How could they ensure that within an hour and a half, Yi Dong would stay at home and wait for them to bomb?

There are too many variables here, but they succeeded in the end. What is the reason?"

Ning Zhiheng's series of questions left Bian Deshou and Yu Cheng speechless. They also reacted at this time. Yu Cheng was also an experienced agent after all, and quickly replied: "When we were investigating, I asked Yi Dong's wife. He said Yi Dong doesn't like to go out for fun, which is the norm, so I ignored this. Now it seems that the Japanese must have done work, forcing Yi Dong to stay at home all the time."

Ning Zhiheng said in a deep voice: "They must have tampered with Yi Dong before, this       ＞＞
