The biggest difference between the two-way mirror and the mirror we usually use is that you can see yourself in the mirror on the front, and others can see you on the back, but you can't find it because all you see is yourself in the mirror.

There have been news such as this at home and abroad: Some people wear bidirectional mirrors in women's dressing rooms, while they hide behind the bidirectional mirrors, admiring the graceful bodies of women, and some even record videos to post online. This has also happened in the shared houses of men and women.

How to distinguish between two-way mirrors and one-way mirrors?

Put the tip of your nail on the surface of the mirror. If there is a gap between the tip of your nail and the reflected image, it is a real mirror. If the tip of your nail can directly touch the reflective image of your nail, you have to be careful, because there is a bidirectional mirror in front of you, and there is a very likely someone is peeking at you behind this mirror.

Zhao Hao suddenly realized that the back of the mirror was hollow, not a wall.

Liao Zhiguo and others, who were still discussing the case, heard a sound of glass breaking and hurried to the bathroom. They saw Zhao Hao holding a shower head in his hand, his fingers were still bleeding, and the mirror on his front was already broken, and there was a dark passage where the mirror was supposed to be a solid wall behind the mirror. This passage was very narrow, and only children or slim people could enter and exit flexibly. Physical figures like Zhao Hao and Liao Zhiguo must not be able to enter.

"Group Zhao, this..." Huang Ke walked to the mirror in surprise and looked down at the situation in the passage.

When Zhou Jiaxin saw that Zhao Hao's hand was still bleeding, she took out the band sticker she carried with her and posted it to Zhao Hao.

After Zhou Jiaxin treated his wound, Zhao Hao said: "The murderers in both cases entered and exited the deceased's house through this passage. Judging from the newness and oldness of the soil on the ground in the passage, this passage was dug up a long time ago."

Liao Zhiguo took out a flashlight and shone it into the passage. There were six obvious traces on the ground. Since there was a thick layer of dust in the passage, as long as someone moved inside, he would definitely leave traces on the ground.

"Go to find the property and ask who the construction party was back then. This passage cannot be opened after the construction is completed, but this passage was left during the construction."

Zhao Hao began to assign tasks: Huang Ke and Liao Zhiguo went to investigate who the construction party was. Liu Tianqi returned to the police station to bring the pathfinding robot, and Zhou Jiaxin returned to the funeral home to conduct in-depth dissection of the two bodies, and did not miss any clues.

An hour later, Liu Tianqi brought the pathfinder robot. He put the pathfinder robot into the passage after setting it up.

The pathfinder robot comes with lighting tools and cameras. As the pathfinder robot deepens, more and more details enter Zhao Hao's field of vision.

There are many mineral water bottles, snack bags, a large number of used tissues and even used contraceptives in this passage. The suspect is lying on the back of the two-way mirror and watching others take a bath and go to the toilet like watching a movie. This kind of perversion is not a small number in life.

The road-exploring robot encountered a fork in the road, and Zhao Hao analyzed that this might be the passage to the first murder scene.

Sure enough, on this passage, Zhao Hao saw dripping blood in the video of the pathfinding robot returning. The internal organs of the deceased at the first murder scene were transported from here. After killing the deceased, the murderer made a lot of disguises, including cleaning the footprints on the washbasin and the handprints in the mirror, so they collected very few clues when they first investigated the scene.

The pathfinder robot has reached its end, and there is another double-sided mirror. Through the mirror, you can still see the scene in the room.

Zhao Hao came to the scene of the first murder and took off the mirror in the bathroom. He found two adsorption handles on the back of the mirror, which was left by the suspect in order to facilitate the reinstallation of the mirror from the back of the mirror. The suspect's fingerprints may be left on it, but Zhao Hao did not have hope for this. How could such a cautious person make a mistake in such a place?

Zhao Hao played back the video of the pathfinder robot returning. At the location of the fork, he saw another fork, which was a three-fork branch passage. Liu Tianqi controlled the pathfinder robot to drive towards the third route. At the end of the road, Zhao Hao saw something like a basket.

He suddenly remembered something, and he came to the debris room next to the elevator to move the basket and cardboard away. A hole was presented in front of him, and the pathfinding robot stopped at the hole...

After a day of investigation, Liao Zhiguo and Huang Ke found the construction party who built the apartment that year. According to the person in charge, there were two people in charge of the debris room at that time. One was Xiang Yanghua, 32 years old, and the other was Wang Bai, 40 years old. Wang Bai died in a car accident two years ago. The person in charge gave Liao Zhiguo and Huang Ke a photo of Xiang Yanghua and Wang Bai's work four years ago.

Seeing the thin Xiang Yanghua, Liao Zhiguo's eyes lit up. The passage at the murder scene was very narrow, and he could only accommodate slim women and children. However, Xiang Yanghua's figure was thinner than ordinary women, and there was no problem in entering and leaving the passage. In addition, he and another person built the miscellaneous room back then, and the other person died in a car accident two years ago, so naturally he ruled out the suspicion.

Liao Zhiguo told Zhao Hao the news, and Zhao Hao ordered the arrest operation.

Xiang Yanghua, who resigned from a construction worker, has been unemployed. According to the police investigation, it was found that he is now living in a rental house. The rental house is located in a not-so-bad community with a monthly rent of 2,300 yuan. Xiang Yanghua did not share the rent with others, but borne the expense alone, which is completely inconsistent with his income.

The arrest operation was led by Qin Hanyu and Liao Zhiguo.

Through the keys provided by the landlord, the criminal police team rushed into Xiang Yanghua's rental house. When they were arrested, Xiang Yanghua was still contacting the buyer through his mobile phone and computer. The things he sold were short videos. The content in the short video was unsightly. They were all videos of some women taking baths and going to the toilet. The victims in the video reached more than 20, most of them were young women, less than 30 years old. He packaged these videos for a price of 50 yuan, and made a profit of nearly 10,000 yuan per month.

In the interrogation room, Xiang Yanghua confessed to the fact that he secretly photographed a woman taking a bath, but he always denied that he had killed someone. The hair left at the scene of the crime was indeed not his, but someone else.

According to his account, not long after the deceased community was completed, he and Wang Bai took turns to peeping women through the two-way mirror to take a bath. At first, they didn’t have much money, so they only bought a custom double-sided mirror. The custom double-sided mirror was made completely according to the appearance of the bathroom mirror, so it was difficult to detect. Later, Wang Bai died in a car accident and he peeped alone.

By chance, he found that someone sold "small videos" online. The construction work with wind and sun made him physically and mentally exhausted, so he thought of taking pictures by himself and selling them himself.

As more and more people buy, he gradually has some savings in his hands. If he wants to retain customers, he has to keep updating the videos. He began to install double-sided mirrors in other homes. Before each installation, he spent a lot of time scouting the spots. This family is alone, and he knows clearly when the women get off work.
