For Xiang Tianliang and Jia Huilan, less than a minute after entering Chen Yulai's house, they understood what happened to Chen Yulai's house.

In a family of three, one person is gone, and the only one is left. The male and female are all in strange expressions, especially the female. The red faces on her face have not faded, and the spring scenery between her eyebrows must have been there. She must have just done "that thing".

After the greetings, Xiang Tianliang sat down, smoked and drank tea, looked at Chen Yu, looked at Hu Wenxiu, and kept smiling.

Chen Yulai and Hu Wenxiu were very embarrassed, especially Hu Wenxiu, who hung his head down in shame.

Jia Huilan poked Xiang Tianliang with his hand, "Hey, why are you laughing at me? They are all people who have experienced it. Can you be serious?"

Xiang Tianliang raised his legs and looked at Chen Yu and said, "Old Chen, you follow Zhang Xing, you have been saying bad things about me behind your back."

Chen Yulai nodded and said embarrassedly, "I'm sorry, but I can say frankly that I just said and didn't do it. Zhang Xing asked me to say it, but when he asked me to do it, I basically didn't listen to him."

"I know this." Xiang Tianliang smiled and said, "Old Chen, it's not me who said you, we are colleagues, and we know the truth. In fact, you should have come to me long ago."

Chen Yulai said twice in a row, "I can call you Tianliang... Tianliang, mainly two people, one is Luo Zhengxin, Fatty Luo, and I have always been in a bad relationship with him, so I misunderstood, thinking that if he gets close to you, he will naturally make me a different book, and the other is Zhang Xing, who is willing to pull me, but I am guarded against him. Later, he caught the pigtails, so I had to be forced to follow him."

Jia Huilan said, "It was dawn. When Lao Lu was in Binhai, Lao Chen was a friend of our family. In fact, Lao Chen was also a good person. You must help with this."

Xiang Tianliang nodded and said, "Old Chen, first of all, I will express my opinion. Huilan and I are here to help you. At the same time, we will definitely keep your privacy confidential."

Chen Yulai's face turned red, "I believe this. When Lao Lu was there, he told me that he had deducted his position and opinions. You admired him very much in his behavior, so he used the opportunity of giving a pen to lay the groundwork and told me to find you when I encountered difficulties. Therefore, when I found that wireless camera probe, the first thought was that I wanted to ask you for help."

After listening to Chen Yu's introduction of "situation", he waved his hand and smiled at Tianliang: "I won't say anything anymore, let the ladies sit, Lao Chen, accompany me to see the two wireless camera probes."

Chen Yulai accompanied Xiang Tianliang. According to Xiang Tianliang's request, the two of them quietly walked around the two bedrooms and returned to the living room.

Then, Xiang Tianliang suddenly thought of something and did not sit down. Instead, he checked the entire living room and confirmed that the living room was safe, and then he breathed a sigh of relief.

Experts will know if there is any one as soon as they take action. This aspect is Xiang Tianliang's masterpiece.

"Old Chen, two wireless camera probes installed in two bedrooms are common tricks on street stalls. You can buy two for a thousand yuan. Don't underestimate this kind of small trick. It has quite high technological content. It has several features: First, it has two functions of video recording, two, it is wireless, and can transmit images and sounds through radio waves. Third, its switch is voice-controlled, that is, it is turned off in a silent state. Once a sound of a certain volume within a certain range sounds, it will automatically start working. Fourth, its micro battery can work for 72 hours, Five, it can send images and sounds through radio waves to a dedicated receiver within 30 meters. Six, after its receiver receives, it also needs a dedicated converter to restore the received signal to images and sounds."

Chen Yu said, "I don't understand this very much in the dawn."

Xiang Tianliang smiled and said, "Note the fifth point I just said, it can send images and sounds to a dedicated receiver within thirty meters through radio waves."

Chen Yulai was stunned for a moment, "Are you sure the conveying distance is not more than thirty meters?"

Xiang Tianliang nodded, "Thirty meters is just a theoretical design distance. With the obstacles of buildings and interference from other radio waves, its actual transmission distance should be about twenty meters, and its optimal transmission distance should be fifteen meters. The images and sounds sent within the optimal transmission distance are the best."

Chen Yulai was slightly stunned again, "That is, that is..."

Xiang Tianliang replied: "That is, the dedicated receiver that takes your home as the basis point to receive these two wireless camera probes should be installed somewhere within a radius of twenty meters."

As he said that, Xiang Tianliang stood up, walked to the window and lifted the curtains and looked out, and walked back and continued, "Old Chen, your house is located on the fifth floor of the apartment building. There is no place to install a receiver outside the window. The exterior wall of the apartment building may also be because the size of the two fists of an adult, it is inconvenient to install and easy to be exposed. There is a basketball court on the floor of the apartment building, and there is no suitable place to hide the receiver... Do you understand what it means if I say that?"

"The special receiver is installed in a room in this apartment building." Chen Yulai said.

Xiang Tianliang smiled and said, "Yes, according to theoretical inference, it is possible from the first floor to the tenth floor. Then, based on a distance of twenty meters, your left and right neighbors, your opposite doors, and your left and right diagonally opposite doors are all the key suspects. In other words, there are many suspects. There are five on this floor, five on this floor, each on the fourth floor, six on each, and three on the first, second, third floor, and seventy or eighty or ninety on each. It's a troublesome to find out."

Chen Yulai shook his head, "Those old neighbors probably won't?"

Jia Huilan interrupted, "Old Chen, it depends on your own judgment."

Xiang Tianliang nodded, "It's very simple, check it first from the most likely person."

Chen Yulai was still thinking, and Hu Wenxiu spoke, "It seems that Wang Zirong, the secretary of Deputy Mayor Zhang Xing, lives here."

"Yes, why did I forget him?" Chen Yulai said to Xiang Tianliang, "Tianliang, I remembered that after Lao Zhao's family on the third floor moved away, the house was empty. Zhang Xing's secretary Wang Zirong got married on May Day, and used the house vacated by Lao Zhao on the third floor."

Xiang Tianliang asked, "What is the third floor room?"

"Just downstairs, it's just the fourth floor of the Old Wang family."

"That's right." Nodded, Xiang Tianliang asked again, "Has Zhang Xing ever been to Wang Zirong's house?"

Chen Yulai said, "I have seen it twice. When Zhang Xing came to my house last Wednesday, Wang Zirong was with him when he went back. Maybe he had been to Wang Zirong's house."

After thinking for a while, Xiang Tianliang asked again: "Old Chen, I am not very familiar with this Wang Zirong. I have only seen him a few times in the municipal party committee compound. What do you think of him?"

After a huh, Chen Yulai said, "I don't know much, I only know that the young man is quite honest. He was brought by Zhang Xing from Qinghe City. He didn't talk much and was quite polite. In short, he couldn't see any characteristics."

"Is he at home now?" Xiang Tianliang asked.

Chen Yu said, "It should not be here. Tomorrow is Sunday. His wife works in Qinghe City and his parents are also in Qinghe City. He should have gone back to Qinghe this afternoon. As far as I know, he usually returns to Binhai to work on Monday morning."

Xiang Tianliang smiled slightly, "Old Chen, you are lucky, and there is a rare opportunity."

"You mean... go to Wang Zirong's house to have a look?"

"Apart from that, there seems to be no better way."

"How to go?"

"Open the lock and enter quietly without leaving any trace."

"you go?"

"And you."

Chen Yulai hesitated, "I, am I going too?"

Xiang Tianliang smiled and said, "Old Chen, you know me. If I go alone, I will take that receiver for myself."

"I'll go, I'll go."

Chen Yulai hurriedly agreed, Xiang Tianliang was indeed good at holding hands, and he was really worried.

Xiang Tianliang said to Jia Huilan, "Sister Huilan, I need you to cooperate with Lao Chen and me in front of the wireless camera probe in the bedroom."

"How to cooperate?" Jia Huilan asked.

Xiang Tianliang said: "There is also a small red light on that special receiver. When it receives a signal, the small red light will flash and shine. So, after Lao Chen and I enter, you will talk in front of the wireless camera probe, and the receiver will start working, the small red light will light, and we will easily find the receiver."

"How do we know you've got in?" Jia Huilan asked again.

"This is very simple. I will call your phone and turn it off if you don't speak. Then you can start talking."

Nodded, Jia Huilan instructed: "It's dawn, Lao Chen has no experience in this area, you should be careful."

Xiang Tianliang responded, "Old Chen, the first thing we have to do now is to confirm that Wang Zirong is not at home or that there is no one in Wang Zirong's family. The way is to call Wang Zirong's family. You should have his landline number?"

"Yes, I'll get it."

Chen Yulai went to the study to collect the vocabulary, found Wang Zirong's name and the fixed number of the residential house, and handed it to Xiang Tianliang.

Xiang Tianliang picked up Chen Yulai's words and called Wang Zirong's house every minute.

No one answered, which means there was no one in Wang Zirong's family.

"Old Chen, let's do the second thing now. Now it's 100 pm. I don't know if there are anyone walking around in the apartment building. You go out now and go to the third floor to take a look."

Chen Yulai left in response.

Jia Yulan was a little worried, "It's dawn, Old Chen is fifty years old, can he do it?"

He smiled and glanced at Hu Wenxiu at Tianliang, "Sister Huilan, you shouldn't ask me this question. Is Lao Chen OK? His family has the most say."

This sentence is easy to understand, "Whether Lao Chen can do it, his family has the most say." This sentence is also very serious.

Jia Huilan laughed silently.

Hu Wenxiu's pretty face turned red.

Xiang Tianliang smiled and added, "Look at it, you can understand it."

Hu Wenxiu felt even more embarrassed.

Jia Huilan glanced at Xiang Tianliang, "Wenxiu is an honest person, don't make fun of her."

As he was talking, Chen Yu came back and forth.

"It's dawn, the third floor is very quiet, and everyone should be asleep."
