Xia An really thinks that the murderer can't be so stupid and easily reveal his identity!

Cheyenne is still extremely sure that it must have been committed by outsiders.

And the murderer, since he entered the hotel from the outside, must have used some kind of trick to make people not find out about his existence.

But how?

When Cheyenne was puzzled, she saw that there were several high-altitude cleaning machines in the hotel downstairs.

When Cheyenne saw this, she suddenly frowned.

When I came in the morning, I didn't notice this!

Cheyenne walked over to the staff over there, "Are you going to clean the windows of this hotel?" ”

The man looked at Cheyenne and nodded, "Yes! ”

"But it's night!"

"We usually come at this point in time, this is an automatic high-altitude cleaning machine, as long as someone is downstairs to control the machine, in fact, it is also convenient to work at night...... And the people in the hotel have thought that if we work during the day, it will hinder the image of their hotel, and we can't help it! ”

Cheyenne nodded.

And after looking at it, this is automatic, in fact, it is also convenient to operate.

It's just that Xia Anhao noticed a problem.

Although the high-altitude automatic cleaning machine here is not big, it is only the size of two people, but it seems that it can also stand on people, right?

Cheyenne Hao had a thought in his head, "Did you guys come here yesterday too?" ”

"That's natural, we started cleaning the windows of the hotel the other day...... However, since I only work at night, it will take a bit of a long time, and it is estimated that it will take a few days to complete the task. However, there are also people watching the machine run below at night, hehe, in fact, it is not troublesome. ”

Cheyenne thought about it and understood.

In other words, these are the machines that clean the windows of the hotel building here, and as long as anyone is here to watch the machinery run?

So, what if there is a person who uses this to go upstairs?

Cheyenne thinks that her idea shouldn't be bold, right?

Xia Anhao was a little excited at this time, "So, what about the person who was in charge of this work yesterday?" ”

The man also pointed to a middle-aged man not far away, "Master Zhang is in charge." ”

When Xia Anhao heard this, he walked to the side of Master Zhang, "Are you in charge of these machines?" ”

Master Zhang looked at Xia Anhao and was a little puzzled, "Well, what's wrong?" Is there a problem? ”

Cheyenne smiled, "It's nothing, I'm just curious about this thing, and I want to ask you something." ”

"This thing is not uncommon, what's so curious!" As he spoke, he pointed to it, "As long as I started them at the beginning, it was actually simple and didn't require me to do anything." ”

"As long as it's activated, doesn't it actually require you to do anything?"

Master Zhang nodded, "Yes!" As he spoke, he pointed to one of the buttons, "Just use this, it's all some work, just add some clean water to the machine." ”

Cheyenne became curious, "So, were you working all the time yesterday?" ”

"That's natural!"

"Did something happen in the meantime? For example, is there a problem with the machine? ”

Master Zhang was stunned for a moment when Xia Anhao asked like this, "Huh? What do you mean? ”

"I'll just ask!"

Master Zhang thought about it seriously, "Something happened last night, I rested for a while, and when I got up, I found that these machines were still working, but according to my estimated time, those machines should have actually stopped downstairs, so how could they continue to work...... But I didn't take it seriously, hehe, it's just a small thing, maybe these machines are a little out of order, I've encountered them before. ”

Cheyenne frowned, it's okay to say if one of these machines fails, but are all of them malfunctioning? Is there such a coincidence?

And that Master Zhang looked at Xia Anhao and muttered again, "Someone asked me about this today, what's wrong, is there any problem?" ”

When Xia An heard what Master Zhang said, her face became ugly.

Someone asked Master Zhang before?

Cheyenne immediately asked, "Did a young man ask you?" Tall and looks ...... The one who is a bit of a ruffian? ”

Master Zhang nodded, "Not really!" He asked me something, and I told him that it wasn't a big deal. ”

Cheyenne became a little nervous, "When did he look for you?" ”

"In the afternoon."

After hearing what Master Zhang said, Xia An's face became ugly.

Did the big brother come in the afternoon?

But now it's evening, which means that the eldest brother had already discovered the problem here two or three hours ago.

But she's only now finding out.

Then, she is one step behind her eldest brother.

What Chu Ze said before was really true, the eldest brother found out about the matter, but he only found out now, this is really his own problem.

Cheyenne was depressed.

If the eldest brother is like this, he will be a lot faster than himself!

Still, there's a chance!

From now on, you must be a little faster than your big brother.

Cheyenne thought about it for a while, what was she going to do next?

After thinking about it for a while, Cheyenne really didn't know how to speed up her pace again.

The information on Meng Keer's side has not come down yet, especially the investigation of Jia Mingyu's circle of friends, let alone the ...... Without information, how can she start?

So, let's take some of the existing things and re-investigate them.

Cheyenne thought about it for a while, and felt that she should watch some of the cameras in the time slot at that time of the crime again.

Thinking of this, Cheyenne Hao hurried back to the hotel.

Some previous camera materials, Xia An used Chu Ze's work card, and asked for a copy of it.

After arriving at the hotel, Cheyenne Hao looked at it again.

Because there is also a camera in front of Jia Mingyu's room, the situation in the time period of the crime can be clearly seen in the camera data.

But from twelve o'clock to one o'clock in the morning when Jia Mingyu died, there was really nothing to pass by here, and there was no one!

Wrong!

Yes there is one!

It's the waiter!

The waiter, Xia Anhao had also seen it before, but he didn't ask anything, and Xia Anhao didn't have much doubts.

But after thinking about it now, there must be something wrong with this!

The only person who entered the room, the waiter, if the murderer wanted to enter, was the only one to rely on.

But there's no problem with that waiter!

Xia Anhao went to ask, the waiter and Jia Mingyu didn't know each other, so it was impossible to do anything to him!

Moreover, the police probably didn't find any problems, otherwise the police wouldn't have let the waiter come back.

Cheyenne stared at the camera again.

I watched the camera several times, but I didn't notice anything at all.

Xia Anhao is serious and continues to watch.

And when I looked at it I don't know how many times, I suddenly found a problem.

It was when the waiter left the room that he seemed to have gone to pick up something from a distance, and then continued to push the food cart.

Before, about this matter, Xia Anhao also asked.

The waiter said that he saw that there was garbage on the ground, and their hotel's requirements were particularly strict, and when he saw such a situation, he naturally picked up the garbage and threw it in the trash can.

Cheyenne thinks it's understandable.

And the waiter, after picking up the garbage, continued to push the cart and left.

Before, Xia Ann Hao didn't find anything.

But when I looked closely this time, when the waiter went to pick up the garbage, I clearly saw that the dining car vibrated a little, and even the tablecloth on the dining car moved.

Well?

How did the food truck shake? How can the tablecloth move?

Even if it's very small, if you look closely, you can still see it.

If there is no external force, how can there be some vibration out of thin air?

Xia Anhao suddenly had a bold idea.

Is there anyone in this food truck?

So, is it possible that the waiter said something that is not so true?

When Cheyenne was thinking about this, she watched it a few more times.

To be sure, she wasn't mistaken.

Cheyenne stood up suddenly, and immediately left the room, and went to the waiter again.

And the waiter was just about to get off work, and after watching Xia An get better, he became puzzled, "Miss Xia." ”

I met with the waiter before, and I asked some things, and he still knew Xia An.

Xia An looked at the waiter, and her face sank at this time, "When I asked you about things before, there were some situations that I didn't say so comprehensively!" ”

The waiter was puzzled, "I told you everything about my previous incident, and I also made a record at the police station." ”

The waiter was a little puzzled, and the police didn't say that he had a problem, but this Cheyenne said that he had a problem.

If it weren't for the fact that the manager in the hotel asked people to cooperate with her, he really didn't want to cooperate with these people...... Getting involved in such a thing, where is the happy thing?

Xia Anhao stared at the waiter, and asked word by word: "There are people in your dining car, why didn't you say anything about this!" ”

The waiter immediately became puzzled, "You said there was someone in my dining car?" As he spoke, he shook his head and vetoed it directly, "It's simply impossible." ”

"But, when I see you push the cart, it's not light!"

Xia Anhao took a closer look again, and the waiter was a little struggling when pushing the dining cart.

The average food truck is actually not that heavy, but why is it struggling?

Naturally, Cheyenne is more concerned about the problem of vibration.

Cheyenne felt more and more that there was something wrong with the waiter.
