"Police officer, although our robot has a camera, it does not go to the stairs, it just turns back and forth in the dining area!" The staff explained to Zhao Yu in embarrassment, "I can't take a picture of the place you are talking about! Moreover, it is not only very slow, but also has the function of automatically avoiding pedestrians. It is obvious that the little boy ran over and installed the robot! They should be asked to pay the money!"

Zhao Yu's meaning is naturally to retrieve the video of the murderer burning 5 million yuan in ransom to see if the robot has photographed any suspicious situations.

He felt that since the Qian Gua was drawn today and the adventure of the dungeon led him here again, it was probably related to the burning of coins.

However, according to the staff, the robot wearing a camera cannot reach the stairs at all. The dining area is quite far from the stairs, so it is impossible for the robot to take pictures.

But... Zhao Yu is very familiar with the adventure system. This seemingly ordinary adventure cannot be unreasonable. Shouldn't it just an ordinary incident in which a child hits a robot?

However, no matter what, since he encountered this robot, he had to bring the robot video back today and check it carefully. What if he could find something from it?

At this time, Xiaopang's mother saw that Zhao Yu was a policeman and was so arrogant. When she heard the staff asking her to pay for money, she no longer dared to say anything, so she quickly pulled Xiaopang away in shame.

The mother and son, who were almost round, slipped into a narrow corridor in the corridor nearby.

Zhao Yu subconsciously glanced at them, and from the signs on the wall, it could be seen that in addition to a bathroom, there was also an elevator in the corridor.

Tsk tsk...

Zhao Yu recalled that when the murderer was burning money, he himself did not come to the building. However, he knew that Li Luoyun had set up controls at all exits of the building at that time! Therefore, there must be someone guarding this exit with an elevator at that time.

But……

"Police Officer... look..." The staff pointed to the robot that was already in shock, not knowing what to do next.

"Stop talking nonsense!" Zhao Yu waved his hand and ordered, "Hurry up and give me the robot's surveillance memory card to assist the police in investigation, and... If there are other robots here, you will also bring all the memory cards for me!"

"No...nothing, this one..."

Before the staff could explain, Zhao Yu ignored him at all. Instead, he frowned and headed towards the corridor where the mother and son left.

Why?

Unexpectedly, when he just turned around the corner, he suddenly saw something fire extinguisher box!

The red boxes were placed on the ground on one side of the corridor, with two red fire extinguishers inside.

Zhao Yu remembered that when the murderer used the homeless man to burn coins, the police officers in charge of surveillance were caught off guard and could only hurry to get the fire extinguisher nearby. But after getting it, they found that the fire extinguisher was broken!

He estimated the distance. Although this place is far away, it may be a fire extinguisher box closest to the entrance of the corridor.

"Hey..." Thinking of this, Zhao Yu quickly waved his hand to the staff and asked, "Do you remember the day someone burned money? At that time, did someone come here to get a fire extinguisher and go to put out the fire?"

"What?" the staff frowned, "I...I don't want to ask the security guard, wait..."

"What are you asking?" At this time, a waiter came out of the restaurant next to him and said to Zhao Yu directly, "You are right. The place where you burn money is at the stairs. This is the closest fire extinguisher box! I looked at it all the time when the money was burned. As soon as the fire broke out, someone here carried the fire extinguisher! Later we found out that the fire extinguisher was completely broken. I heard that a lot of money was burned!"

Oh...so...

After hearing what the waiter said, Zhao Yu understood the situation that day. The person the waiter mentioned should be the plainclothes police officer who was responsible for the elevator. After hearing the news of the fire there, the police officer quickly carried the fire extinguisher to put out the fire, but he did not expect that the fire extinguishers were all broken.

Later, Li Luoyun also investigated this matter and believed that the fire extinguisher should have been tampered with, and the person who tampered with the tampered with the murderer was undoubtedly an accomplice of the murderer!

However, they later searched the person in charge of the building to investigate the situation. Since there was no camera in the fire extinguisher, they never found valuable clues.

The building security personnel can confirm that the fire extinguishers are not only full, but also new. In addition, through inspection, they also confirmed that the two fire extinguishers have not been replaced, and they were still the two originally installed in their building!

Thinking of this, Zhao Yu entered the corridor and went to the fire extinguisher box to check. Needless to say, all the fire extinguishers now must have been replaced with new ones.

So... how did the murderer move?

Did he pour out the dry powder from the fire extinguisher in advance? But... how did he pour it out?

Why?

Zhao Yu almost unconsciously thought of the bathroom inside, so...will the murderer come over early, turn on the fire extinguisher, and pour all the dry powder into the bathroom?

Thinking of this, he walked to the bathroom again. The corridor is not large and the bathroom is very mini.

Zhao Yu noticed that there was a camera at the elevator entrance on the right. However, he knew that the camera should be invalid! The entire corridor was full of a blind spot for surveillance.

After observing for a while, he walked into the men's bathroom and checked it. The facilities in the men's bathroom were also very simple, with no toilet, only two squat toilets and two urinals.

Tsk tsk...

Zhao Yu is not very good at fire extinguishers, but he instinctively felt that the dry powder in the fire extinguisher should not be so easy to pour out.

So he immediately took out his cell phone and searched briefly from the Internet. He was surprised to find a fact. It turned out that if the fire extinguisher fails to work, there is no need to spend the fire extinguishing powder in the fire extinguisher. He only needs to use a simple tool to release the pressure in the fire extinguisher, and the fire extinguisher will lose its function!

oh……

Zhao Yu then understood why Li Luoyun and the others gave up the clue of the fire extinguisher. Since there is no video surveillance in this place, there are many people coming and going, so it is difficult to find out who has touched those two fire extinguishers?

Tsk tsk...

Zhao Yu thought about it carefully and felt more and more that he seemed to be doing a useless task.

Because he has seen several professional killers such as the windbreaker man and has captured two alive. So, the person who has touched this fire extinguisher is likely to be one of these people.

In other words, even if you find out the original part of the fire extinguisher yourself, it will be useless!

But……

For some reason, Zhao Yu always felt unwilling to give up. First, he thought that the adventure of the dungeon would mean something; second, he always felt that there seemed to be another mystery in this small fire extinguisher.

However, Zhao Yu is now in a hurry and must rush back to the hospital as soon as possible.

When Zhao Yu left, the staff naturally did not dare to neglect and quickly handed over the robot's monitoring memory card to Zhao Yu.

After returning to the car, Zhao Yu was still a little unwilling to give up, so he simply connected the memory card to the tablet and started watching.

In fact, Zhao Yu didn't think too much. He almost unconsciously adjusted the video to the moment of burning money, wanting to see if the robot would take some photos when burning money.

As a result, the coincidence that Zhao Yu had been looking forward to happened!

But at the same time when 5 million was burned, the robot happened to pass by the corridor where the fire extinguisher was located. From the video, he could even clearly see a plainclothes policeman rushing to put out the fire with a fire extinguisher.

In order to see more clearly, Zhao Yu moved the timeline forward and then looked carefully. Unexpectedly, this time, it was amazing. His heart couldn't help but slammed and his hair exploded!

Oh My God!
Chapter completed!
