Ning Zhiheng and others soon came to the residence of Yi Dong's family. This was an independent house. Although the area was not large, it was already a rare residence in Chongqing.

The yard was cleaned from inside to outside, and it was obvious that the hostess was a neat housewife.

When I first met Yi Dong's wife, this woman was about thirties, with a pretty face but couldn't cover up a trace of sadness. She looked at Yu Cheng with a faint expression. Behind her was a seven or eight-year-old girl, who was Yi Dong's daughter.

Yu Cheng stepped forward and said kindly, "I'm so sorry, Mrs. Yi, I'll ask you again today, some things about Mr. Yi."

Mrs. Yi said hesitantly: "Team Leader Yu, you have asked several times. I have said everything I should say. It has been more than a month. Give me a truth, is there a problem with my husband's death? Didn't he be killed by the Japanese?"

Mrs. Yi is also a shrewd person. From Yu Cheng's several contacts, it can be seen that the headquarters of the Military Intelligence Bureau did not agree with Yi Dong's death. It was just that Yi Dong was bombed to death by Japanese planes. The whole process was clear and she couldn't think of what was wrong.

Yu Cheng looked at Mrs. Yi for a moment and didn't know how to answer. Ning Zhiheng behind him said, "Mrs. Yi, Mr. Yi is really important to our Military Bureau. His death surprised the military bureau very much, so we have to be careful about the cause of his death, but don't worry, this is the last investigation, and we will not disturb you again afterwards."

Mrs. Yi looked up at Ning Zhiheng. The tall young man looked serious and solemn. She nodded and agreed, "No matter where, I can't disturb us. The bureau is very caring about our mother and daughter. I still know that it's better. If you have any questions, please ask."

Mrs. Yi asked several people to sit in the house and poured tea for them. Ning Zhiheng then asked: "We just want to ask today whether there were any abnormalities on the day of Mr. Yi's death. Although it was the 16th and the day of rest, we know that he often worked overtime, so why didn't he work overtime that day?"

Mrs. Yi replied softly: "My husband is too busy with work and rarely spends time with us. It was a rest day. He was in a rare good mood during that time and was going to accompany us to watch a movie, so he didn't go to work."

Ning Zhiheng asked strangely: "Watch a movie? But you didn't go in the end?"

Mrs. Yi sighed and said sadly: "This is fate! If we go, my husband may not be killed by the Japanese. When I wake up in the morning, my husband feels a little uncomfortable and dizzy after walking a few steps. This is also his old habit. I usually take some medicine and take a rest.

So we didn't go out. We took some medicine at home and lay on the bed to rest. But not long after, the Japanese plane came. He refused to go to the air-raid shelter like before. I had to leave with my daughter. Who knew that the luck was so bad this time..."

After saying that, Mrs. Yi could no longer hold back her tears and started sobbing gently.

Sure enough, Ning Zhiheng and others had a problem, and they asked quickly: "When did Mr. Yi feel uncomfortable, before or after breakfast?"

Mrs. Yi recalled it carefully and replied: "It was before breakfast. He felt dizzy when he woke up early in the morning, but it was not bad, itchy, it was neither painful nor itchy. He just stood for a while and it was fine if he had more rest."

"Have Mr. Yi had this symptoms before?"

"I have seen a few times before, but I have seen a doctor in the bureau. The doctor said it was because of the nervous problems caused by excessive brain use and anxiety. Just take more rest and take some medicine."

"Mr. Yi is anxious during this period?"

"No, he was in a good mood those days. He said that things went well at work. The bureau also rewarded him with some money, otherwise he would not be in the mood to take us out to see a movie."

Ning Zhiheng and Yu Cheng looked at each other, and then asked, "Did Mr. Yi eat anything the night before the accident?"

The Japanese tampered with Yi Dong just because they were eating and eating. Since they felt uncomfortable when they woke up in the morning, they were likely to be hit the night before.

"The night before?" Mrs. Yi thought carefully and continued, "The dinner I ate at home the night before was all the food I stir-fried. There was nothing special. At most, I would stir-fry a few more dishes to serve them."

They? Ning Zhiheng suddenly felt energetic, and he asked in a deep voice: "Mr. Yi drank that night? Who did you drink with?"

"Who else? Gu Zhengqing, the two of them often drank a few drinks together. That night, they had to come over to drink with my husband, so I had to fry some wine and they chatted until very late."

Gu Zhengqing and Ning Zhiheng immediately showed a figure in his mind. It was the man in his early thirties I saw in the decipher room today. He was quite friendly to Ning Zhiheng and was not colder than others.

Yu Cheng explained: "This Gu Zhengqing and Mr. Yi both returned from studying in Japan. They are about the same age, so their relationship will naturally get closer."

But Ning Zhiheng disagreed a little. He heard Mrs. Yi's tone and seemed to not like Gu Zhengqing, so he continued to ask: "Why did this Gu Zhengqing come to Mr. Yi to drink? Just to chat? Is there anything wrong?"

Mrs. Yi shook her head and replied, "I don't drink anymore, so I went back to the house early to take my child to rest. I don't know what they said, but this Gu Zhengqing is not a serious person, and I rarely talk to him."

When talking about Gu Zhengqing, Mrs. Yi's tone was very unhappy, and it can be seen that she did not have a good impression of Gu Zhengqing.

"Mrs. Yi seems to be very dissatisfied with Gu Zhengqing. Is he disrespectful to Mrs. Yi?"

Ning Zhiheng knew from the investigation information that Gu Zhengqing had always been single and had no girlfriend. Will he have any inappropriate thoughts about Mrs. Yi and arouse Mrs. Yi's disgust.

Mrs. Yi shook her head and said, "Many people know about Gu Zhengqing. I am not talking about right and wrong after I am not here. You can find out if you ask for it casually."

The implication is obviously unwilling to say more. It can be seen that Mrs. Yi is somewhat cultural and well-educated, not as good as an ordinary woman with ordinary aunts and sisters.

Ning Zhiheng was not forced to do anything, and then asked, "Is there anything unusual about Gu Zhengqing's behavior compared to usual? Is all the food for supper yours?"

"Nothing is different, it's the same as usual. However, every time he comes to drink with my husband, he always brings a bottle of good red wine. My husband loves to drink. In the past, when my family is in good condition, my husband had the habit of drinking red wine. Later, when the war broke out, the Yi family fell into ruin, and we ran around. After we arrived in Chongqing, the conditions here were even more difficult. We couldn't afford a bottle of good red wine."

Mrs. Yi's words suddenly attracted everyone's attention. Ning Zhiheng asked: "Did Mr. Yi drink the red wine brought by Gu Zhengqing?"

"Yes, I always bring you my family. The Gu family has a good family background and can always get some good things, no better than us." Mrs. Yi confirmed.

"Will Gu Zhengqing drink red wine when he was eating?"

"He doesn't drink it, he likes to drink white wine, and red wine is specially prepared for my husband."

Ning Zhiheng nodded, he felt a little relieved, and then he asked some questions, then stood up and said goodbye.

The group left the Yi family and discussed the results of today's investigation while walking.

Yu Cheng said, "I was negligent before. Now it seems that Gu Zhengqing is a traitor. He is Yi Dong's friend. Naturally, he knows that Yi Dong suffers from claustrophobia, he also knows that he has dizziness, and is a core member of the deciphering team. He also knows that Yi Dong has begun to decipher the Japanese military code, so he began to plot the murder of Yi Dong.

On the night before the rest day, I took the opportunity to drink at home and tampered in red wine, so that Yi Dong would drink it, causing Yi Dong to relapse. Yi Dong was not feeling well, and he could only rest at home as usual. Then Japanese bombers flew over the sky. Taking advantage of the alarm sounding and everyone hid in the air-raid shelter, Gu Zhengqing arranged for his accomplices to arrange bombing signs. Yi Dong refused to enter the air-raid shelter as usual, and was bombed to death by the bomber. In this way, everyone thought Yi Dong died unexpectedly. He eliminated Yi Dong without knowing it. Gu Zhengqing could continue to lurk safely. It was really easy to plan. Unfortunately, he was discovered from the beginning and is still in our hands."

Ning Zhiheng fully agrees with Yu Cheng's judgment. At present, Gu Zhengqing's suspicion is too great.

He suddenly remembered something and turned to Bian Deshou and asked, "Old Bian, Mrs. Yi just said that Gu Zhengqing was unbearable and didn't know what his father's woman is. Do you know what's going on?"

Bian Deshou is the butler of these deciphering experts, responsible for taking care of the daily life of these people, and should also know about these situations.

Bian Deshou heard Ning Zhiheng's inquiry and said, "In fact, it is not as serious as Mrs. Yi said. These are all gossips. The thing is that Gu Zhengqing's father works in the Ministry of Finance. More than half a year ago, he fell in love with a young woman who fled. The woman's husband was beaten to death by a riot on the way to Chongqing. He was alone and had no relatives in Chongqing. Later, due to a livelihood, he committed to the Gu family. Government officials cannot take concubines, so he has no status. However, it was reported that Gu Zhengqing had some connection with this woman. Gu's mother showed her power and drove the woman away. Gu Zhengqing had a long awkward relationship with his father for this reason, and then slowly eased down. In fact, according to my opinion, his father was disrespectful to his old age, which was not a good way."
