After Chen Guihua finished speaking, she turned around and rushed to the door, opened it, and started to curse.

Mo Xiaoqing had no choice but to follow her out. At this time, Chen Guihua was so angry that she had lost her mind. She grabbed the neighbor woman's hair and banged her head against the wall.

"You betrayed my daughter. We are a bunch of murderers. I will kill you today. Not only is there an old beast in your family, but there is also a little beast!"

"You are really a villain who complains first. You are not a faithful wife, and you want to seduce my husband. Now the retribution has come!"

All kinds of vicious and cruel words came out of the mouths of the two women.

Xu Yao showed the police ID to stop the fight between the two women. "You are so brave to fight in front of us police officers."

This farce attracted other residents on the entire floor to watch the excitement.

"Forget it, go away." Xu Yao dispersed the residents who were on the move, and the farce came to an end.

Mo Xiaoqing had a vague insight into some facts from the direct verbal abuse of the women just now, and felt that Chen Guihua's neighbor's family was a little strange.

After Chen Guihua returned to the room, Mo Xiaoqing asked her why she was so sure that her daughter was killed by the neighbor's family, and how the grudge between her and the neighbor came about?

The layout of the room in their community is that the kitchen and bathroom are connected, and the window faces the corridor. The neighbor's family had only one child. One day, she found the neighbor's son standing at the window and peeping at her eldest daughter taking a bath.

Chen Guihua scolded the neighbor's son, and the resentment between the two families became more and more serious, and finally reached the point of being incompatible.

After listening to Chen Guihua's explanation, Xu Yao stood up and decided to go to the neighbor's house to find out the details.

"Captain Xu, do you also think there is something strange about the neighbor's family?"

Xu Yao knocked on the neighbor's door without saying anything. The woman who had just quarreled with Chen Guihua became much more docile after seeing the police.

After Xu Yao entered the house, he asked directly, "Are you alone at home now? Where are your husband and son?"

The woman rubbed her hands and replied, "My husband doesn't get off work until nine o'clock, and my son usually comes home from school around six o'clock."

Xu Yao stood up and walked around the room. Although the room was narrow, it was decorated quite warmly and cleanly.

After asking, I learned that her husband's name was Li Fu, who sold pork in the nearby vegetable market, and her son Li Dexin was now in the third year of high school and chose to go to school instead of boarding.

As Chen Guihua said, the two families had disliked each other for a long time and quarreled every few days, but fortunately, the children of the two families did not have any barriers and would play together behind their parents' backs.

The neighboring woman always blamed Chen Guihua for seducing her husband, and thought that her husband must have had an affair with Chen Guihua.

After asking, Xu Yao stood up and walked around the room. The room was very tidy, and there were all kinds of tableware in the kitchen. In a corner of the stove was a complete set of knives, some of which were of amazing size.

The hostess explained in a panic: My husband sells pork and needs all kinds of sharp knives. She also realized that some knives are controlled items and took the initiative to admit her mistake.

Xu Yao came to the side bedroom, turned around and asked the hostess, "Is this your son's room? Can I go in and take a look?"

The woman nodded.

Mo Xiaoqing followed him in. There was nothing special about the room. There was a wardrobe next to the bed and a large desk on the windowsill. There were rows of comics and many discs on it. There were

also many extracurricular books on medicine. When Mo Xiaoqing saw the human skeleton model standing behind the door, she couldn't help but be shocked.

There was a photo album on the bedside table. Mo Xiaoqing flipped through it and was shocked. It was full of photos of a girl. Judging from the shooting angle, they should have been secretly taken. The heroine of the photo was none other than the twin sister Xiang Xinyi.

When Mo Xiaoqing was about to take the photo album to show Captain Xu, she heard the sound of a key opening the door.

Heavy footsteps were heard, followed by an irritable male voice, "Wife, why did you let the police rummage through the room!"

Xu Yao had no choice but to take Mo Xiaoqing out of the room and tried to explain, "Hello, your neighbor's two daughters were murdered, and we came here to find out what happened."

"Comrade police, do you have a search warrant? You can interrogate, but even the police can't rummage through citizens' private belongings without permission!" a burly middle-aged man said unhappily.

Xu Yao didn't bother with him and asked directly: "I neglected it, sorry. But I still have to ask you, what were you doing at around 11 o'clock on the evening of October 1st?"

"Sleeping, I was so tired from work every day, so of course I slept with my wife in my arms." The middle-aged man took out a toothpick and picked his teeth, and replied with disdain.

"Who can prove it?"

"Who! Of course it was my wife and son."

"You mean that your whole family was sleeping that night and didn't go out?" "

Yes, officer, have you finished asking questions? If you have, please go in! Don't disturb us ordinary people from having dinner. It's not easy for us to make money, unlike you who work for the country."

After listening to this, Mo Xiaoqing puffed up her cheeks and wanted to argue, but was stopped by Xu Yao's eyes.

Xu Yao said politely, "Sorry to disturb you while you're having a meal. We're leaving now!"

Mo Xiaoqing opened the door with a rage. Just as she was about to go out, there was a boy with a schoolbag on his back standing outside the door with a key in his hand. He had a pale face and timid eyes, and looked very depressed and shy.

The boy walked into the room with a shy smile. Before he put down his schoolbag, he heard the man's roar, "You little brat, why did you come home at seven o'clock today? Where have you been?"

After that, he saw the middle-aged man slap the boy on the back of his head. The woman ran out of the kitchen to rescue him, "Son's father, can you hit him without knowing the truth?"

"I hit him, so what? As long as I don't like someone, it's not too much to kill him!"

Mo Xiaoqing followed Xu Yao out of the door, and there was a noisy quarrel inside...

"Captain Xu, I just saw the photo album on the bedside frame in the room. It was full of secretly taken photos of the deceased Liu Xiangyi." Mo Xiaoqing reported to Xu Yao when she went downstairs.

Xu Yao was very calm and just asked, "What does that mean?"

"It means that the neighbor's son has a crush on the twin sister, and he is obsessed with her. I can't really explain what it means, but I just feel that there is something strange about the neighbor's family."

Xu Yao jumped into the car and made a phone call, "Xiao Liu, arrange for someone to monitor Chen Guihua's neighbors 24 hours a day, and report any suspicious points immediately."

Mo Xiaoqing asked excitedly, "Captain Xu, do you also think that they are related to that couple? " Is it related to the twin murder case?"

Naturally, Xu Yao did not answer. Mo Xiaoqing also slowly got used to being ignored by Xu Yao, and started talking to herself again, "The neighbor family has a deep grudge against Chen Guihua's family, which can constitute a motive for murder. Moreover, they only claimed that they were all asleep at home on January 11, and there was no time for witnesses, which is also very suspicious.

So this family is likely to be the suspect."

"Well, there is some truth in your analysis, but Officer Mo Xiaoqing, it's time to get off work now, please get off the car!"

Mo Xiaoqing stared with her mouth open, unable to recover. She was kicked off the car by Captain Xu halfway. She pouted her lips and wanted to negotiate,

"Captain Xu, it's ten minutes to drive to my house, or you..."

Before Mo Xiaoqing finished her words, Xu Yao's car braked suddenly and her head hit the seat.

"You came here by yourself today. It's time to get off work now. Please take care of yourself!" Xu Yao raised his eyebrows and gave her several glances.

Mo Xiaoqing got off the car slowly. As soon as her feet landed on the ground, she heard a car next to her roar and whizzed past.

"Xu Yao, you cold-faced uncle, why are you so arrogant! If I didn't really enjoy investigating cases, I wouldn't bother to put up with your anger!"

"Ah, I'm so mad! You just threw me on the side of the road like this. Do you know anything about gentlemanly manners? Do you know how to be gentle with women? Ah!!!"

Mo Xiaoqing's scolding naturally didn't fall into Xu Yao's ears. After throwing the little one out of the car, he was in a good mood. He drove towards the bar street in Kuala Kangsar with the music blasting.
