"Beep beep beep!" Niu Bing and Xiao Ying came to the door of Han Ying's house. Niu Bing rang the doorbell. In a short while, a slight sound of footsteps came from inside. The footsteps stopped behind the door for several seconds, and then left again.

"What, I'm not at home?" Xiao Ying frowned.

"At home, I heard footsteps and saw us, but I didn't want to open the door for us." Niu Bing said, and rang the doorbell again.

"Why didn't she open the door?" Xiao Ying said.

"I don't know." Niu Bing naturally couldn't know why the other party didn't open the door, but he was not lacking in patience. The doorbell stopped and he rang the doorbell again. After he rang the doorbell for the fourth time, the door finally opened.

"It's you, have you heard of the murderer?" Han Ying didn't have much emotional fluctuation when he saw Niu Bing and Xiao Ying.

"Not yet. We'll look for you, hoping to know some specific situations." Niu Bing said.

"Oh!" Han Ying brought the two into the living room, but obviously they were not welcomed, and they didn't even mean pouring a glass of water. Niu Bing and the others had not sat down yet, as the master, she sat down first.

"Han Ying, who have you told us about what we are looking for?" Niu Bing didn't care about Han Ying's welcome. It was a good idea to let them into the house. As a vassal who was killed by her husband, the police have not solved the case for more than four years. Do you think how good the attitude of others is? As for the other party may be one of the suspects, they are probably even more unwelcome to their visit, and they don't even want him to continue investigating. Knowing that the other party is not welcome, Niu Bing has no intention of relying on it here, and directly enters the subject matter. Moreover, doing so also means a sudden attack.

"Captain Niu, I have never told anyone. You have said hello, how could I tell anyone?" Han Ying shook his head, looking impatient.

"Han Ying, I wonder if you can tell me how did you know that I was the captain of the team?" Niu Bing looked at Han Ying with his eyes and asked lightly. He did not expect that with this casual question, the other party actually exposed a huge loophole. The last time he and Xiao Ying came to Han Ying to find Han Ying, it could be said that he was handling the case in violation of regulations. At that time, he was the director of Taihong Police Station and the person who was faked to instruct the criminal police team. That time, he did not even reveal his identity. The main target was Xiao Ying, and he was just recording it on the side, and he had not even mentioned his name.

"Captain Niu, didn't I call you that when you came last time?" Han Ying looked confused, but there was a slight panic flashing in her eyes, and she slightly dodged Niu Bing's eyes.

"Han Ying, when we came last time, Captain Niu was not the captain of the criminal police brigade, but the director of Taihong Township Police Station. You are not clever at all." At first, Xiao Ying really didn't notice that there was something wrong with Han Ying's name, but when Niu Bing said it, she naturally reacted instantly.

"I remember, that's what I called you. Did I remember it wrong..." Han Ying's expression became more nervous.

"Han Ying, when Niu came last time, he didn't even say anything about his surname. Should I look at the inquiry record? This is signed by you. Should I look at what you said?" Xiao Ying took out the last inquiry record.

"I..." Han Ying shut up.

"Han Ying, I'll ask you again, who have you told you about what we are asking for?" Niu Bing continued to speak, but his voice seemed much more serious. Before, although he was a little suspicious about Han Ying, he was not very suspicious. An ordinary person, you cannot expect him to abide by the confidentiality system. Especially, Han Ying's mother has a less likely chance of keeping it confidential. The reason why he told them not to tell them was just to hope that they could keep it a little secret and not to say too much. In this way, as long as they are not the suspect, even if they talk to some close people, they may not be able to pass it to the suspect. But now, Han Ying actually knows his identity, the problem is definitely not simple. At least, the person she comes into contact with knows him, and Han Ying deliberately conceals this news. The behind the incident must be not so simple.

"..." Han Ying didn't say anything, and even the panic in his expression did not appear.

"Since that's the case, then go to the criminal police team to make it clear." Niu Bing suddenly stood up.

"Captain Niu, I don't know if you are summoned or something?" Han Ying seemed very confident.

"Come out, don't hide there and eavesdrop... Li Fanming..." Niu Bing suddenly pushed open the door of the room on the left. He had heard that there was someone behind the door, but he didn't care much at first. After all, Han Ying is also a widow now. Even if there is a man or something at home, it is not a strange thing. However, when he opened the door, he was stunned. Li Fanming was not unfamiliar with Li Fanming. He was originally an old senior from the criminal police team, but later resigned and left the criminal police team. However, that was all about Niu Bing before he entered the criminal police team. He didn't know the reason, nor was Li Fanming known in the criminal police team; Li Fanming is now a small boss in the gravel field. What made Niu Bing stunned was not only because Li Fanming was once a member of the criminal police team, but also because Li Fanming was Yuan Zheng's brother-in-law. There was also a record of Li Fanming in the original case file, and Niu Bing still remembered that Li Fanming in the record suspected Han Ying.

"Niu Battalion, I'm sorry, I told Han Ying about your news." Li Fanming was not very panicked when he saw Niu Bing, but instead felt embarrassed. However, it explained in one sentence that Han Ying knew the origin of Niu Bing's identity.

"Boss Li is very concerned about Niu." Niu Bing looked at Li Fanming lightly.

"Captain Niu is a sensible figure in the criminal police team. I have been in the criminal police team for several years. I can't even know if I don't know." Li Fanming had a sarcastic expression.

"Then we won't bother Boss Li and Miss Han." Niu Bing did not mean to stay here. With Li Fanming here, they could not get more from Han Ying's mouth. Li Fanming is an old detective, but it is not so easy to deal with. Even if you ask Han Ying alone, it may be difficult to get anything. Han Ying is not an easy role. According to the records of the investigation at that time, Han Ying is not a simple person. According to Yuan Zheng's sister Yuan Mei, Han Ying had been a lady before, and Han Ying was more of a reception in the dance hall, while Yuan Zheng herself was more of a maintenance of the order of the dance hall and some official responses. If such a woman was not a suspect, they could still understand some situations, but now it is not easy. After all, with Li Fanming here, she must know that they have no evidence and she can't speak out. At the time, they will not do anything to her.

"Captain Niu walks slowly." Li Fanming was very polite on the surface.

"What should we do now?" Xiao Ying asked in a low voice after leaving the gate and going downstairs.

"Go and see Yuan Mei. Maybe we can know some of the situation from her." Niu Bing said lightly. Li Fanming's appearance made him no longer necessary to investigate secretly. Everything was exposed, and he was still investigating secretly.

"Yuan Mei is a worker in the sanitation center. She always works night shifts when sweeping the streets. At this time, we should be at home. However, we should be quicker. Li Fanming will go home later." Xiao Ying and the others had never contacted Yuan Mei. According to previous investigation records, Yuan Mei was determined to believe that it was her sister-in-law who killed her brother. For her brother's case, she even struggled with the criminal police team for nearly a month. It is said that the criminal police team later found the leader of the sanitation bureau and stopped. Because they were worried that Yuan Mei could not control her emotions, they did not dare to contact Yuan Mei, so as not to be exposed in their investigation. After all, they investigated secretly, and Niu Bing was only the director of the police station at that time and had no right to investigate at all. However, Xiao Ying still had the same grasp of the secret contact.

"Yeah!" Niu Bing also heard Xiao Ying talk about Yuan Mei's situation.

The two of them came to Yuan Mei's house and seemed to have good luck. Yuan Mei had just returned home with a large basket of vegetables in her hand and was about to open the door. Perhaps it was because of her work, or perhaps it was a habit. Yuan Mei was obviously a woman who didn't care much about her image. At this time, he was wearing work clothes.

"Hello, are you Yuan Mei?" Xiao Ying asked.

"You are..." Yuan Mei looked at Xiao Ying in confusion, and then at Niu Bing. She didn't know the two of them.

"We are from the Criminal Police Team of the Public Security Bureau. This is Niu Bing, the deputy captain of our Criminal Police Team." Xiao Ying showed her police officer certificate.

"From the Criminal Police Team... you came for my brother's case..." Yuan Mei's voice was a little excited.

"Yes, we came for your brother's case." Xiao Ying nodded.

"Please come in quickly, please come in quickly..." Yuan Mei was obviously much more enthusiastic than Han Ying. She couldn't wait to let the two of them into the house and immediately made tea for them. Moreover, she obviously took out the tea treasured at home.

"No need to worry..." Niu Bing said softly.

"Captain Niu, you must make the decision for my brother. My brother died so miserably... It's been four years, and I often dream about him that they are all that bitch, but he and the wild man killed my brother..." Yuan Mei's voice was not loud, but she was crying and seemed very excited.

"You have a good relationship with your brother?" Niu Bing did not dissuade Yuan Mei, but asked softly after Yuan Mei had almost vented.

"Well, my brother is only one year older than me. We have been together since kindergarten and until we graduated from junior high school. My father originally asked my brother to take over, but my brother insisted on letting me take over the work. He said he was a man and it was easy to find a job," he paused slightly, and Yuan Mei said in tears, "He went to work as a porter and worked for more than four years. Because of his poor work and a temporary worker, he was not guaranteed. He couldn't find a partner. Later, he twisted his waist and could no longer do heavy physical work. Life was even more difficult. He went outside to work and met that bitch... They met in a dance hall. I didn't know at the time, and I was happy for my brother..."
