"Police officer, although our robot has a camera, it doesn't go to the staircase. It just goes back and forth in the dining area!" The staff member explained to Zhao Yu. "It can't capture the place that you are talking about! Moreover, it's not only very slow, but it also has the function of automatically avoiding pedestrians. It's obvious that the little boy ran over and installed the robot! They should pay for it! "
What Zhao Yu meant was that he wanted to retrieve the video of the murderer burning the five million ransom to see if the robot had captured anything suspicious.
He felt that since he had gotten a Qian hexagram and the side adventure had led him there, it was likely that it had something to do with the burning of the money.
However, according to the staff member, the robot with the camera couldn't reach the stairwell at all. The dining area was quite far away from the stairwell, so it was impossible for the robot to capture anything.
But … Zhao Yu knew the miracle system very well. This seemingly ordinary side adventure couldn't be without reason. It couldn't just be an ordinary incident of a child running into a robot.
Anyway, since he had encountered the robot, he had to take the video of the robot back and check it carefully. What if he could find something from it?
At this time, the fat boy's mother saw that Zhao Yu was a police officer, and that he was being so rude. She didn't dare to say anything more, so she quickly pulled the fat boy away.
The mother and son, whose bodies were almost round, slipped into a narrow corridor near the stairwell.
Zhao Yu glanced at them subconsciously. From the sign on the wall, he could see that there was a bathroom and an elevator in the corridor.
Tsk tsk …
Zhao Yu recalled that when the murderer burned the money, he didn't come to this building. However, he knew that Li Luoyun had placed guards at all the exits of the building! So, the exit with the elevator must have been guarded at that time.
But …
"Police officer … You see …" The staff member pointed to the robot, who was in shock. He didn't know what to do next.
"Stop talking nonsense!" Zhao Yu waved his hand and ordered, "Hurry up and give me the memory card of the robot to help the police investigation. And … If you have any other robots here, give me all of their memory cards!"
"No … No, this is the only one …"
Before the staff member finished explaining, Zhao Yu ignored him. He frowned and walked towards the corridor where the mother and son had left.
Eh?
Unexpectedly, just as he turned the corner, he suddenly saw something — a fire extinguisher box!
A red box was placed on the ground on one side of the corridor. Inside the box were two red fire extinguishers.
Zhao Yu remembered that when the murderer used the homeless people to burn the coins, the police officers who were in charge of surveillance were caught off guard. They could only rush to get the fire extinguisher nearby. When they got it, they found that the fire extinguisher was broken!
He estimated the distance. Although this place was quite far away, it was probably the closest fire extinguisher box to the staircase.
"Hey …" Zhao Yu quickly waved at the staff member and asked, "Remember the day when someone burned money? At that time, did someone come here to get a fire extinguisher and extinguish the fire? "
"What?" The staff frowned, "I … I'll ask the security. Wait a minute …"
"What are you asking?" At this time, a waiter came out of the restaurant next door and said, "You're right. The place to burn money is at the staircase. This is the nearest fire extinguisher box! I saw everything that happened that day. As soon as there was a fire over there, someone went over with the fire extinguisher! Later, we found out that the fire extinguisher was broken. I heard that a lot of money was burned! "
Oh … I see …
Hearing the waiter's words, Zhao Yu roughly understood what had happened that day. The person that the waiter was talking about should be the plainclothes police officer who was on duty at the elevator. After hearing that there was a fire, the police officer quickly went over with the fire extinguisher, but he didn't expect that the fire extinguisher was broken.
Later, Li Luoyun investigated the matter and thought that the fire extinguisher must have been tampered with. The person who tampered with it was undoubtedly the murderer's accomplice!
However, when they checked with the person in charge of the building, they couldn't find any valuable clues, as there were no cameras at the place where the fire extinguisher was placed.
The building's security personnel confirmed that the fire extinguisher was not only full, but it was also new. In addition, they also confirmed that the two fire extinguishers hadn't been replaced. They were the original two fire extinguishers in the building!
Thinking of this, Zhao Yu entered the corridor and checked the fire extinguisher box. Needless to say, the fire extinguishers must have been replaced.
So … How did the murderer tamper with the fire extinguisher?
Did he pour out the dry powder in the fire extinguisher in advance? But … How did he pour it out?
Hey?
Zhao Yu subconsciously thought of the bathroom inside. Then … Could the murderer have come over in advance, turned on the fire extinguisher, and poured all the dry powder into the bathroom?
Thinking of this, he walked over to the bathroom. The corridor wasn't big, and the bathroom was very small.
Zhao Yu noticed that there was a camera on the elevator on the right side. But, he knew that the camera was probably not working! The entire corridor was a blind spot for surveillance cameras.
After observing for a while, he walked into the men's bathroom to check it out. The facilities in the men's bathroom were very simple. There weren't any toilets, only two squat toilets and two urinals.
Tsk tsk …
Zhao Yu wasn't very familiar with fire extinguishers, but he instinctively felt that the dry powder in the fire extinguisher wouldn't be easy to pour out.
So, he immediately took out his phone and did a simple search on the internet. Then, he was surprised to find out something. It turned out that, in order to make the fire extinguisher useless, there was no need to pour out the powder in the fire extinguisher. All one needed to do was use a simple tool to release the pressure in the fire extinguisher. Then, the fire extinguisher would lose its effect!
Oh …
Zhao Yu then understood why Li Luoyun and the others had given up on the clue of the fire extinguisher. As there wasn't any surveillance in the area, there were many people coming and going. So, it would be difficult to find out who had touched the two fire extinguishers.
Tsk tsk …
Zhao Yu thought about it carefully, and the more he thought about it, the more he felt like he was doing something useless.
He had already seen the man in the trench coat and a few other professional killers, and he had even caught two of them alive. So, the person who had touched the fire extinguisher was most likely one of them.
In other words, even if he found out the origin of the fire extinguisher, it would be useless!
But …
He didn't know why, but Zhao Yu didn't want to give up. First, he felt that there must be a reason for the side quest. Secondly, he felt that there was something more to the small fire extinguisher.
However, Zhao Yu was pressed for time, so he had to rush back to the hospital as soon as possible.
When Zhao Yu left, the staff naturally didn't dare to delay, so they quickly passed the memory card of the robot to Zhao Yu.
After returning to the car, Zhao Yu was still unwilling to give up. He simply connected the memory card to the tablet computer and looked at it.
Actually, Zhao Yu didn't think too much about it. He subconsciously played the video to the moment when the money was being burned. He wanted to see if the robot would capture anything when the money was being burned.
In the end, the coincidence that Zhao Yu had been looking forward to happened!
At the same time that the five million dollars were being burned, the robot happened to pass by the corridor where the fire extinguisher was located. From the video, he could clearly see a plain-clothed police officer carrying a fire extinguisher and rushing to put out the fire.
In order to see it more clearly, Zhao Yu moved the timeline forward again and looked at it carefully. Who knew that with this look, it would be terrible. His heart couldn't help but let out a thump and his hair stood on end!
Oh my God!
