When Ning Zhiheng heard this, he suddenly felt that he had little relationship in Nanjing City, and only the Zuo brothers and sisters were his hidden subordinates, so it was not convenient to go directly to the Military Intelligence Investigation Office to find him, while the others knew their units.

For example, the peripheral personnel under Liu Datong can call directly to find themselves.

If these people can find their place of residence, they must know their unit, but no one comes to them during this period. In other words, they are secretly asking about their whereabouts. Who would do this?

Ning Zhiheng has always been careful in his work and will not let go of any clues, let alone someone is secretly asking for information about him, which is related to his own safety, and will anyone be targeting him?

Who is investigating himself? Will it be the same as the last time he was outside the military intelligence investigation office, that the Japanese were targeting him?

But the last time their target was all the internal officers of the Military Intelligence Investigation Department. Before they could find their own heads directly, they simply found their residence this time. Will this mean that their goal is clearer this time?

Ning Zhiheng smelled a trace of crisis. If his guess is good, it is really a Japanese who came to him, it means that he has been included in the key survey subjects by them. The situation is much more serious than the last time. It seems that the security forces around him must be strengthened.

Ning Zhiheng is not the kind of young man who likes to show off his heroes. This is an era of hot weapons. It is too easy to take a person's life. A shooter with good marksman needs only one gun and one bullet to send a good man who has been practicing martial arts for many years into the gates of hell. If someone really wants to take his life, only a few good gunmen are enough. Even if he is caught off guard, he can only regret it.

Zhuge was cautious in his life and was careful to sail the ship for thousands of years! It would be no harm to do more precautions, as it seemed that his residence was no longer safe.

Thinking of this, he said to Zuo Gang: "Which family told you exactly?"

"Just the fourth family to the right of your house, it is a middle-aged woman. She is not tall and speaks with a little Sichuan voice." Zuo Rou replied, specifically, she went to inquire about Ning Zhiheng. After all, a girl can easily eliminate the other party's vigilance and make it easier to do things.

Ning Zhiheng recalled this family in his mind. This family is from Sichuan and has a family of four. He has never dealt with each other normally, but just nodded and said hello.

Ning Zhiheng nodded and said, "Don't go to my residence during this period, and I won't go back for the time being. I will make a decision after I investigate it clearly. If there is anything, I will notify me directly on the public phone."

"Young Master, do you want us to investigate?" Zuo Gang said rushingly. It is obvious that Ning Zhiheng attaches great importance to this situation, which means there must be a problem. "These people have found your residence and will not go too far. We can ask around and see if there are any strangers appearing?"

Ning Zhiheng thought about it carefully and felt that the Zuo brothers and sisters should not come forward. If it was as he thought, it was indeed the Japanese who came to him, then it would be most appropriate to hand over such a thing to the Military Intelligence Investigation Office. The Zuo brothers and sisters will be exposed when they participate. Ning Zhiheng did not want others to know about the existence of the Zuo brothers and sisters, otherwise their future actions would be inconvenient.

He shook his head and said, "It is not convenient for you to come forward to these things. I will call others to deal with them. Don't act rashly, just wait for my notification."

The Zuo brothers and sisters nodded and agreed. Ning Zhiheng did not stop for much. They quickly left the Zuo family and rushed back to the Military Intelligence Investigation Office. When they returned to the office, they immediately called Sun Jiacheng.

"Old Sun, go out in plain clothes immediately and find a way to bring my residence to the fourth family on the right. A Sichuan couple brought me here. The movements should be hidden and don't disturb anyone. I have something to ask them." Ning Zhiheng ordered.

"Yes, I'll do it right away!" Sun Jiazhen took the order and left.

Before the matter was investigated clearly, Ning Zhiheng would not return to his residence or show up near his residence. He couldn't help but be glad that he had not returned home during this period, otherwise someone would really want to plot against him. Even if he had the ability to warn him, he was afraid that it would be unpredictable if he was anxious. After this incident, the residence could no longer be used.

Two hours later, Sun Jiacheng brought a middle-aged couple back. The couple walked into the office in fear until they saw that it was Ning Zhiheng, and their expressions suddenly relaxed.

"It's really Mr. Ning, but we were so scared that we were very worried. What was there to bring us here?" The couple said. Sun Jiacheng forced them over on the way home, which scared them so much that they thought they had met a villain. When they saw that they were really their neighbors, they felt relieved.

Ning Zhiheng smiled and signaled, letting the couple sit down on the sofa, then poured two cups of tea and put them in front of them, and said in a kind tone: "Mr. Yang, Mrs. Yang, I'm so sorry. I'm too busy with work and I really don't have time to disturb me in person, so I have to let my men go and invite you here."

Ning Zhiheng didn't have much time to deal with the neighbors, but he just vaguely remembered that their surname was Yang and he couldn't even remember the specific name.

When Mr. Yang saw Ning Zhiheng's attitude and calm, he felt secretly calm. Although Ning Zhiheng had been a neighbor with them for more than half a year, he had very little time to deal with him, so they did not know very well about Ning Zhiheng's situation. He only knew that this was a young officer, but now it seems that this neighbor is not a simple person.

"Mr. Ning called us here, what's wrong?" Mr. Yang asked.

Ning Zhiheng didn't take any turns and asked straight to the point: "That's right. I've been too busy with work for a while and haven't been home. But I heard that someone was near my residence and asked about my situation, Mrs. Yang seemed to know something, and I don't know if I could tell me."

The couple then realized what Ning Zhiheng meant. Mrs. Yang immediately said, "Mr. Ning's news is so well-informed. Don't say anything. Someone is asking about your news."

"Okay, then please tell me the situation carefully." Ning Zhiheng asked quickly.

"A total of two people came to inquire about your news, one was eight days ago, one was a man, and the other was two days ago, one girl. This girl was so delicate." Mrs. Yang thought for a moment and said.

Ning Zhiheng knew that the girl two days ago must have been Zuo Rou. What’s important is that the man who asked about his actions eight days ago was the target he was looking for.

"Please tell me carefully about the situation of the man eight days ago, and what questions he asked specifically? Please give it a little more details." Ning Zhiheng continued.

When Mrs. Yang heard that it was a little embarrassed. The incident had been too long and she couldn't remember much. She had to try her best to describe it: "At noon eight days ago, I happened to wash vegetables in the yard. A man in a ragged dress knocked on the door and asked for a drink. I saw that he was pitiful and gave him a bowl of water to drink.

I chatted a few times while drinking water, and he said he was here to join a distant relative. He only knew that his relative's surname was Ning and he was a young officer. I thought it was just for you, so I told your address.

Later he asked me if you usually go home. I said I don’t know, sometimes I come back, sometimes I don’t come back. But later he asked me, when you look, you said your appearance is not as good as you are too bad, so you must have found the wrong person. I was quite disappointed and left after drinking the water."

After listening to Mrs. Yang's words, Ning Zhiheng thought about it carefully, and then asked again: "What accent he fucked?"

"I only know that it is the northern accent, which is not very obvious, and is different from the local accent," Mrs. Yang replied. Later, she seemed to remember something again, "the accent is similar to the old man who repaired shoes at the intersection of the street."

"Old Cheng is from Shandong." Mr. Yang, who was standing beside him, said in a flash.

Ning Zhiheng couldn't help but nodded secretly. During this period, as long as Japanese spies who were proficient in Chinese, most of them had northern accents, and generally had some accents from Northeast or Shandong.

This situation also exists among the Japanese spies he contacted, such as Huang Xiansheng before, Xie Ziming, Meng Lesheng later. According to people from the intelligence department, Yan Yichun also had a Northeast accent, and Ning Zhiheng was exposed to Kawamoto Kurashi, who also had a few Northeast accents.

This situation was caused by the environment at that time. There was no Mandarin confirmed in later generations in this era, and the accents of each local dialect are very different.

Many years ago, the Japanese targeted the northern regions, so the first Japanese forces infiltrated northern provinces and cities, such as the Northeast and Shandong areas. They captured a large number of workers from the Northeast and Shandong. Many spies learned Chinese from these workers at that time.

Chinese is very difficult to learn, and it takes a lot of time and energy to learn. It takes at least several years to say exactly like Chinese people.

Therefore, most of the Chinese language learned by Japanese spies during this period was spoken language in this area, so most of the so-called Chinese language in the Japanese are like this.

Of course, there is nothing absolute in the world. Some Japanese spies have a southern Chinese accent, but this situation is rare. After all, the south is a battlefield that the Japanese have only opened up over the years. Even if they want to learn southern accent, it will take a certain amount of time.

When Ning Zhiheng thought of this, he continued to ask: "Can you describe his height, appearance and clothes in detail?"

Mrs. Yang said in embarrassment: "It took a while and I left in just a few words. I really can't remember it."

Ning Zhiheng smiled and said, "It doesn't matter, Mrs. Yang, you can just say as much as you can remember, and you don't have to force it."
