Time passed by bit by bit, the sun had completely set, and Hu Qianqiu was still standing by the guardrail of the rooftop thinking about things.

Seeing Hu Qianqiu falling into deep thought, Song Xiao couldn't interrupt him with words, so he could only sit aside and stare at the night sky in a daze.

"Have it!"

Hu Qianqiu suddenly spoke, which really scared Song Xiao. He covered his chest and complained: "What are you doing? I'm scared to death."

Hu Qianqiu turned his head to look at him, and smiled and said, "I have found a breakthrough!"

When Song Xiao heard about the matter related to the case, he immediately became interested, "Do you have new clues?"

Hu Qianqiu nodded and told him his thoughts.

Many criminals will install pinhole cameras in hotels and secretly shoot videos of couples. The hotel where Yu Xuefei was involved happens to be a couple hotel, so the probability of pinhole cameras being installed in the room Yu Xuefei opened during her lifetime is very high.

If you can find a pinhole camera, although you cannot know the specific floor where Yu Xuefei fell, you can at least know the identity of the most mysterious man in black.

"Wonderful, why didn't I expect that I won't call you Mr. Hu in the future, let's call you Hulmes."

"Don't rush to flatter, it's not certain whether you can find it."

Hu Qianqiu and Song Xiao got off the rooftop. Due to the lack of electricity, the entire hotel was pitch black, so the two could only use the flashlight of their mobile phones to illuminate them.

Because of insufficient light sources, the entire hotel looked gloomy and chilling. Hu Qianqiu was calm, but Song Xiao was a little uncomfortable and subconsciously got closer to Hu Qianqiu.

When Hu Qianqiu was in the police station, he heard Lin Qingyun say that the room number of Yu Xuefei was 421. After he and Song Xiao arrived on the fourth floor, they found that this floor seemed to be colder than other floors.

Song Xiao swallowed, "Mr. Hu, you can't turn on the central air conditioner anymore."

"Don't talk nonsense, the entire hotel has no electricity, where does the air conditioner come from? It must be a psychological effect."

Having said that, Hu Qianqiu was also unsure of it. This strange feeling was very similar to before he entered the Yin-Yang Realm that night.

At this time, a gust of wind blew from Hu Qianqiu's back, and the hairs on his neck stood up.

The two of them were in the passage on the fourth floor, and there were no vents in front, back, left and right. How could there be wind?

Suddenly, one hand grabbed Hu Qianqiu's shoulder, and the muscles on his body suddenly became tense. He turned around and turned around and it turned out to be Song Xiao.

Hu Qianqiu breathed a sigh of relief and was about to curse Song Xiao, but his heart suddenly became hung.

At this time, Song Xiao leaned forward, and it seemed that he had encountered Hu Qianqiu in great difficulty, while Song Xiao was looking at the other person with horror.

"I was caught by something..."

Hu Qianqiu was shocked and slowly set his eyes on

The flashlight moved to the position of Song Xiao's feet.

"Your sister..."

It turned out that there were two adjacent holes on the carpet here, and the carpet was wrinkled at this time, and Song Xiao's feet were just passing through it, so he couldn't move just now.

Song Xiao pulled his feet out and looked at Hu Qianqiu embarrassedly, "It is inevitable that people are a little nervous in this place."

Hu Qianqiu did not deny it and asked, "Are you blowing at me behind your back just now?"

Song Xiao looked at him with a puzzled look, "No, am I full? Besides, I'm so far away from you just now, how can you feel the breath of breath at you?"

The hair on Hu Qianqiu's body suddenly stood up again.

Although I don’t know what the cold wind behind the scenes was like before, Hu Qianqiu and Song Xiao could only investigate. Due to the previous accident, both of them seemed extremely careful in every move.

After exploring for a while, the two finally arrived in front of Room 421.

Since the doors of the rooms that passed by were tightly closed, the two of them thought that the same should be true for Room 421, but what they did not expect was that the door lock of the room of 421 was damaged and the door was not closed.

"This is probably done by the man standing on the rooftop this afternoon. No matter what the other party's purpose was, at least we can know that she is investigating Yu Xuefei's death like us."

Song Xiao nodded, "Get in quickly, maybe someone has taken the lead, I don't want to go there in vain."

This room is not big, except for the special beds, other than the ordinary hotels, it is no different from those in ordinary hotels.

Hu Qianqiu knew that pinhole cameras usually faced the bed, sockets, TVs, bedside lamps, etc., which were good places to hide pinhole cameras, but he and Song Xiao searched for a long time but had no gains.

Song Xiao said: "Online, it is said that when turning on the mobile phone camera in a dark environment, if there is a red dot, it is likely that it is the infrared light of the camera."

After Song Xiao finished speaking, he asked Hu Qianqiu to turn off the flashlight of his phone, and at the same time turned on his phone camera and searched in every corner of the room. After searching for a long time, he did not find a pinhole camera.

Song Xiao said discouragedly: "We may have to go for a waste of time. It seems that there is no camera in this place."

Hu Qianqiu smiled and shook his head, "That's not necessarily the case. Nowadays, many mobile phone cameras filter infrared rays. Even if there is a camera, you may not be able to find it with your method."

When Song Xiao heard this, he didn't say much, and turned on the flashlight of his mobile phone and started from scratch.

The two of them worked hard for a long time and searched almost every corner of the room. It was already eight o'clock, but they still found nothing.

Hu Qianqiu lay on the bed disheartenedly, "Stop looking for it, either there is no pinhole camera in this place, or it is taken away by the person who came before."

Song Xiao said "ah"

I was also lying on the bed, "I worked hard for a long time, but I didn't have any farts, and I even made my back sore. No, I have to find a place to massage later."

Hu Qianqiu sneered, and when he was about to get up and leave, he suddenly noticed the ceiling of the room.

There is a ventilation opening on the ceiling of the room, which is also a good place to install a pinhole camera. Installing a pinhole camera there allows you to take pictures of the bed and the surroundings.

Hu Qianqiu took off his shoes and stood on the bed, reaching out to reach the vent.

The height of this room is not too high. With Hu Qianqiu's height and the height of the bed itself, you can reach the ventilation vent by placing your feet.

The iron fence of the vent was not installed firmly. Without using tools, Hu Qianqiu tinkered for a while and removed the iron fence of the vent.

With a muffled sound, an object fell from the ventilation opening and fell onto the bed.

Song Xiao immediately pointed the light of the flashlight at the object. Hu Qianqiu looked down and saw that it was the camera.

This type of pinhole camera is not connected to the power supply and works by relying on the battery, so it is larger and thicker, so it cannot work for a long time. Moreover, this pinhole camera is only connected to a memory card, and has no signal transmitting and receiving devices, so it cannot be transmitted in real time. It can only be watched after recording is completed.

Hu Qianqiu looked at the camera and said, "The person who installed this pinhole camera should have replaced the battery and memory card regularly. It seems that it is mostly the staff of the hotel itself. After Yu Xuefei's accident, the hotel closed down and rectified, so the camera was not taken away, and the memory card inside was naturally not replaced."

Song Xiao was overjoyed and was so excited that he couldn't help but scream.

Hu Qianqiu was much calmer. He took out the memory card of the pinhole camera and looked at it. This card had a capacity of 16G, so I don’t know how many videos he had shot.

Hu Qianqiu and Song Xiao have not eaten since noon. Before, they were focused on finding things but were not hungry. Now, when they relax, they suddenly felt hungry. After they finished their meal in a nearby restaurant, it was almost nine o'clock.

While having dinner, Song Xiao also learned through his mobile phone that the afternoon incident had spread on the school forum, and the more he spread, the more outrageous it became. In the end, the school came forward to put pressure on the matter, and did not spread further out.

Hu Qianqiu had to sigh at the school's decisive behavior. If this matter spreads to the outside world, after the media hype, I don't know what kind of uproar it would cause.

Although it was not too late at this time, there were already very few pedestrians on the road in this remote place. However, Hu Qianqiu and Song Xiao were not ready to go back to school, so they decided to buy a card reader first to see what was taken in the video.

Originally, Hu Qianqiu wanted to hand over the card to the police, but on the one hand, it was difficult to explain the origin of the card, and on the other hand, he couldn't suppress his curiosity, so he decided to find a way to hand it over to the police after reading it.
