The car drove all the way to Qianfushan's community and to the guard room. Ding Xiaoqian asked the other party to cooperate directly. When the security guard in the community saw that it was a policeman, it was reasonable and readily called out the surveillance video.

"With Liu Detong's personality, will he leave such a fuck?" Ye Xiao was a little confused, but he still stared at the screen intently.

The young security guard rubbed his hands: "This is this month. If anything else is needed, I'll find you. Is there something big happening in our community?" He seemed to see this female police officer coming to this community a few days ago, but it was not convenient to ask at the time, so he didn't ask. In fact, he was curious and nervous.

When I saw the female police officer, I didn't know that she was a female police officer. I just thought she was a high school student with a very good temperament. I walked side by side with a man with a very good temperament. For some reason, I looked full of justice, so even though I was close, he didn't stop him.

Xiao Hu replied casually as he looked at it: "Do you know all the residents in this community?"

The young security guard laughed and said, "Of course, I patrol eight times a day, can I not touch it clearly?"

"Oh, then do you know that this community lives in Unit 302, 2, Building 7?" Xiao Hu raised his eyes slightly, still careless.

"Is it the fifty-year-old leftover woman?" the young security guard searched his memory carefully and asked.

Xiao Hu waved his hand: "No, everyone has children, and they are less than fifty years old."

"Oh, I understand! It's the one opposite the fifty-year-old left-hand woman! The man is a wax figure, with a beautiful wife and a child, they are their family, right? They live in the opposite building, I only know where to live, and I don't know which room you are in. I will know when you say this." The young security guard showed a sudden expression.

Ding Xiaoqian stared at the surveillance video, but his ears were listening to the conversation behind him.

Xiao Hu said in surprise: "You actually know that family?" I think Qian Fushan is a low-key and honest person. Isn't there anyone dealing with him?

"I know, no matter how I've been here for a while, I still have some impression of the resident users here." The young security guard said truthfully.

The surveillance video in August flashed by. If Liu Detong was the murderer, then Liu Detong would come to find Qian Fushan and would probably not be photographed by the monitor. Then it would be futile to observe the monitor. But what if? Ding Xiaoqian was a little unwilling to give up. The so-called wise man will be careless. How can he ensure that Liu Detong will not neglect this?

Ye Xiao looked at another security guard who was unfamiliar with his computer and tried hard to call out the videos from the previous few months. Unfortunately, he was reluctant but lacked strength. Ye Xiao was anxious to watch it, and snatched the mouse and patted the security guard: "I'll do it."

The security guard stood up obediently, and Ye Xiao sat up.

Ding Xiaoqian was relieved when he saw Ye Xiao adjusting the video himself. If it were Ye Xiao, he would not have misunderstood.

"Have you noticed who does that family often contact?" Ding Xiaoqian turned around and asked.

The young security guard recalled seriously: "That... he didn't look very eye-catching at first, but the reason he remembered him was entirely because he always came alone and didn't like to talk to others. However, for such a long time, there have been one or two times that he brought a few people to his house, maybe he was a guest."

"Who? When?" Ding Xiaoqian asked immediately.

The young security guard was startled by Ding Xiaoqian's speech speed and quickly replied: "Wait, I think about it carefully. It seems... it seems that once was a year ago, and there was another time... it might have happened last month, yes, it was indeed last month."

"What kind of person was with him that time last month?" Ding Xiaoqian took the key point. Last month was the same as Lu Heng's death, so it was more suspicious.

"When I first came last year, there were a lot of them. It should be his boss and employees. One was a little older, and then two or three younger ones were left. The only one who came last month."

Ding Xiaoqian asked carefully: "How can you be sure that the person is the boss?"

"Oh, that person has a good temperament and a gentle temperament. The employees who walk on the road are surrounded by him invisibly, and they look like a leader."

Ding Xiaoqian wanted to continue asking, but suddenly Ye Xiao said in surprise: "I found it!" Ding Xiaoqian quickly turned his head to look, and Jiang Yu and Xiao Hu also surrounded him.

Ye Xiao excitedly lit the five squares on the screen: "This one is located at the gate, and only took a little bit, but according to the screenshots behind, it can be confirmed that it was him. It seems that he is indeed hiding from the monitor, but he can only see the monitor placed at the door, and cannot see the monitor inside the community. So the four pictures behind are one at the corner of Building 1, one in the middle of the flower bed, one in front of Building 3, and one on the left side of Building 7. He did not hide from these four places, so he shot the complete video."

"Copy this video." Ding Xiaoqian unconsciously rubbed his lower lip with his fingers and made instructions.

"Okay." Ye Xiao said, lit the mouse quickly, took out the USB flash drive and moved the data. The security guard standing next to him was stunned. He didn't know that the computer could operate like this. This was the first time he had seen someone who was so powerful. As expected, the strong one had his own strength. It must be very difficult for those who could handle cases in the police station. Thinking of this, the security guard silently looked at the four people who came, especially Ye Xiao became the tallest in his eyes.

Seeing the blue bars on the screen reaching the end, Ye Xiao whistled a beautiful whistle, pulled out the USB flash drive and handed it to Ding Xiaoqian: "Perfect!"

Ding Xiaoqian nodded in the USB flash drive. Although this is not certain evidence, it at least shows that Liu Detong and Qian Fushan had contact during the period before the incident.

"Wait a minute, what is that?" Just as Ye Xiao was about to stand up, Ding Xiaoqian's aftermath swept to Liu Detong on the screen.

Ye Xiao nodded and looked at the screen.

On the screen, Liu Detong was holding a box in his hand. It was night when Liu Detong went there, so due to the light, the box in his hand was blocked by the shadows, so it was not clear.

Ye Xiao enlarged the box and found that it was a cardboard box about 30 cm high and about 40 cm long. The cardboard box was exquisitely packaged, like a gift box for multi-layer cakes.

"Birthday cake?" Xiao Hu blurted out.

Ding Xiaoqian looked at Xiao Hu, and Xiao Hu explained: "This is a very famous mid-range cake shop with its own special logo and independent packaging design."

"Who is someone in Qian Fushan's family celebrates his birthday?" Ye Xiao frowned and said. He had read the information of the deceased and no one celebrated his birthday in July. But there is also a situation where the birthday of the ID card is different from the real birthday. But this situation cannot be verified.

"Birthday? That's really strange." The security guard wrapped his hands behind his back and interjected half-moviely.

"Oh?" Confusion flashed in Ye Xiao's eyes.

"His wife is petty when she goes out to buy vegetables, and she has hardly seen any snacks his children have eaten, let alone cakes." The young security guard said with a smile, as if she looked down on Qian Fushan's lifestyle.

Ye Xiao couldn't help but frown, obviously unable to understand Qian Fushan's family's actions.

When the young security guard saw everyone confused, he continued to explain: "He bought a second-hand house for this house. The price had tripled the original price at that time, but he paid in full. The car he drove was Audi and the parking space was an underground parking space. Obviously he was not short of money, but he was just stingy. I was so impressed by him not only because he didn't like to talk, but also because I saw how he treated his wife."

"How did you treat it?" Xiao Hu blinked with interest. As a single dog, Ding Xiaoqian and Xu Ziqian were tortured every day. He really couldn't imagine how ordinary people lived.

The young security guard smiled and said, "I went to buy vegetables that day and met his wife. Three onions cost three yuan and seven cents. The woman told the stall owner that she wanted to change one, because the quota given by her husband was three yuan and five yuan, and it could not exceed three yuan and five yuan. At the same time, the stall owner disliked her for a few cents, and she simply refused to sell it to her. Then she went to another house in shame. This was not something like this. In addition, she saw his son wanting to buy anything, but was rejected by the woman, because her husband was not allowed to spend useless money. This was the first time I saw such a rich but so stingy person. I think he should be a wealthy slave."

Ding Xiaoqian frowned. He didn't have any opinions on Qian Fushan's lifestyle, but suddenly thought of something.

"Why do you want that much money? If you don't spend it, you can't take it away even if you die." Xiao Hu twitched the corners of her mouth, thinking that it was true that there were birds in the forest.

Jiang Yu suddenly said, "Is it because I am so reluctant to spend money? Have you ever suffered from having no money before?"

Ding Xiaoqian looked at Jiang Yu thoughtfully and said nothing.

Ye Xiao replied in a rare manner: "It seems that it would be great if he could find his elementary and junior high school classmates."

"There is no such thing. It may have existed, but it was burned to ashes or thrown away." Xiao Hu denied that Qian Fushan's home and suitcase were searched, and he didn't even take photos with his family, let alone any other photos.

Ding Xiaoqian pushed the glasses frame and said seriously: "According to Erikson's psychological development concept, the main development task in infancy is to gain a sense of trust and overcome doubt; in late in infancy, it is to gain a sense of initiative and overcome shame; in early childhood, it is to gain a sense of initiative and overcome guilt; in childhood, it is to gain a sense of diligence and overcome inferiority.

Qian Fushan is suspicious and unwilling to share money with his wife; he is extremely shy and unwilling to talk to others; he lacks self-knowledge and reflective ability, is extremely inferior, and silently bears the insults and suppression from the outside world; the above points show that Qian Fushan’s 0-12 years old is not happy.
