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

Song Xiao saw that Hu Qianqiu was deep in thought, and he couldn't interrupt him with words, so he could only sit aside and watch the night sky in a daze.

"There it is!"

Hu Qianqiu suddenly spoke, which really startled Song Xiao, he covered his chest and complained: "What are you talking about, I'm scared to death." ”

Hu Qianqiu turned his head to look at him and said with a smile: "I have found a breakthrough!" ”

When Song Xiao heard about the things related to the case, he suddenly became interested, "Do you have a new clue?"

Hu Qianqiu nodded and told him what he thought.

There are many criminals who will install pinhole cameras in hotels and secretly shoot videos of couples, and the hotel where Yu Xuefei had an accident happens to be a love hotel, so the probability that the room opened by Yu Xuefei before her death is very likely to be installed with pinhole cameras.

If you can find the pinhole camera, although you can't 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 think of it, I won't call you Hu Shao in the future, just call you Holmes."

"Don't be in a hurry to pat yourself on the back of the ass yet, it's not certain whether you can find it."

Hu Qianqiu and Song Xiao got off the rooftop, and due to the lack of electricity, the entire hotel was dark, and the two could only use the flashlight of their mobile phones to illuminate.

Because of the lack of light source, the whole hotel looked gloomy, which made people shudder, Hu Qianqiu was quite calm, but Song Xiao was a little uncomfortable, and subconsciously got closer to Hu Qianqiu.

When Hu Qianqiu was at the police station, he heard Lin Qingyun say that Yu Xuefei's room number was 421, and 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 his saliva, "Hu Shao, this won't turn on the central air conditioner." ”

"Don't talk nonsense, the whole hotel has no electricity, where is the air conditioner, it must be a psychological effect."

Having said that, Hu Qianqiu also had no bottom in his heart, this strange feeling was very similar to before he entered the Yin and Yang Realm that night.

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

The passage between the two of them on the fourth floor has no vents in the front and back, left and right, how can there be wind?

Suddenly, a hand grabbed Hu Qianqiu's shoulder, and the muscles on his body suddenly tensed, and he turned around suddenly, it turned out to be Song Xiao.

Hu Qianqiu breathed a sigh of relief, and just wanted to scold Song Xiao, but his heart suddenly hung up.

At this time, Song Xiao leaned forward, and it seemed that it was extremely difficult to meet Hu Qianqiu, and Song Xiao was looking at it with a frightened expression.

"My foot was grabbed by something......"

Hu Qianqiu was shocked, and slowly moved his gaze and flashlight to the position of Song Xiao's feet.

"Your Sister's ......"

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

Song Xiao pulled his foot out and looked at Hu Qianqiu curtly, "It's inevitable that people are a little nervous in this place." ”

Hu Qianqiu didn't deny it, and asked, "Did you blow on me behind my back just now?" ”

Song Xiao looked at him with a puzzled expression, "No, am I full?" Besides, I was just so far away from you, how can you feel it blowing on you? ”

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

Although they didn't know what was going on with the yin wind behind them before, Hu Qianqiu and Song Xiao could only investigate hard. Due to the previous accident, the two of them were extremely careful in their every move.

After fumbling for a while, the two finally arrived in front of room 421.

Since the doors of the rooms they passed through before were all closed, the two of them thought that room 421 should be like this, but what they didn't expect was that the door lock of room 421 had been broken and the door was not closed.

"That's probably what the guy standing on the rooftop did this afternoon. No matter what the other party's purpose is, at least we can know that she is investigating Yu Xuefei's death just like us. ”

Song Xiao nodded, "Come in, maybe someone has already taken the lead, I don't want to run in vain." ”

This room is not very big, except for the special bed, it is not different from a normal hotel in other aspects.

Hu Qianqiu knew that pinhole cameras were generally aimed at the bed, and sockets, TVs, bedside lamps, etc. were all good places to hide pinhole cameras, but he and Song Xiao searched for a long time to no avail.

Song Xiao said: "It is said on the Internet that when you turn on the mobile phone camera in a dark environment, if there is a red dot, it is likely to be the infrared light of the camera." ”

After Song Xiao finished speaking, he asked Hu Qianqiu to turn off the flashlight of his mobile phone, and at the same time turned on his mobile phone camera and searched all corners of the room, but after looking for a long time, he did not find a pinhole camera.

Song Xiao said discouragedly: "We may have to run for nothing, it seems that there are no cameras in this place." ”

Hu Qianqiu smiled and shook his head, "That's not necessarily, now many mobile phone cameras filter infrared, even if there is a camera, most of them can't be found with your method." ”

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

The two of them were busy for a long time, searching almost every corner of the room, and the time was already eight o'clock, but they still found nothing.

Hu Qianqiu lay on the bed in frustration, "Don't look for it, either there is no pinhole camera in this place, or it was taken away by the person who came before." ”

Song Xiao sighed and lay on the bed, "I've been busy for a long time, I don't have any farts, and I have back pain, no, I'll have to find a place to massage later." ”

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

There is a vent in the ceiling of the room, which is also a good place to install a pinhole camera, where you can install a pinhole camera to take pictures of the bed and all around.

Hu Qianqiu took off his shoes and stood on the bed, reaching for the vent.

The height of this room is not too high, with Hu Qianqiu's height, plus the height of the bed itself, you can get to the vent with a cushion.

The iron fence of the vent was not installed firmly, and without the help of tools, Hu Qianqiu dismantled the iron fence of the vent after a while.

There was a muffled sound, and an object fell through the vent and landed right on the bed.

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

This kind of pinhole camera is not connected to the power supply and relies on the battery to work, so the volume is large and relatively heavy, and it cannot work for a long time, and this pinhole camera is only connected to a memory card, there is no signal transmitting and receiving device, it cannot be transmitted in real time, and it can only be watched after recording is completed.

Hu Qianqiu looked at the camera, "The person who installed this pinhole camera should have regularly replaced the battery and memory card for it, so it seems that most of them are the staff of the hotel itself, and after Yu Xuefei's accident, the hotel was closed for rectification, and this camera has not been taken away, and the memory card inside has naturally not been 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, looked at it, this card has a capacity of 16G, I don't know how many videos have been taken.

Hu Qianqiu and Song Xiao haven't eaten since noon, before the two of them concentrated on finding something and didn't feel hungry, but now as soon as they relaxed, they suddenly felt hungry, and after the two of them finished eating in a nearby restaurant, it was almost nine o'clock.

And Song Xiao also learned through his mobile phone during the meal that the afternoon's incident had spread in the school forum, and the more outrageous it became, and in the end, it was the school that came forward to put pressure on the matter, and it did not spread further outward.

In this regard, Hu Qianqiu also had to sigh at the school's resoluteness, if this matter spreads to the outside world, I don't know what kind of uproar it will cause after the media hype.

Although it was not too late at this time, there were very few pedestrians on the road in this remote place, but 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 captured in the video.

Originally, Hu Qianqiu wanted to hand over this card to the police for processing, but it was difficult to explain the origin of this card, and secondly, he couldn't suppress the curiosity in his heart, so he decided to find a way to hand it over to the police after reading it himself.
