Chapter 3508: Adventure Exploration 2

The ultrasonic detector was placed on a trolley with cleaning equipment. Pushed by the sausage, walked all the way through the passage.
Several other mercenaries are responsible for cleaning and cleaning, but they are not slow. Lin Rui took a notebook while walking and recording.
"Hey, you. Come here!" As if seeing Lin Rui taking notes, a guard immediately stretched out his hand to say hello.
"Are you talking to me? Sorry, we are very busy now." Lin Rui shook his head.
The guard walked to him and took the notebook from him, "What are you memorizing?"
"This is a cleaning record. The building is so big, we have to remember clearly which area has been cleaned and which area has not been cleaned.
It will be safer to record in this way, so as to avoid repetitive work in some places and not clean up in some places. Lin Rui replied, "Is there any problem?" "
The guard looked at the logbook and wrote some numbers on it. Can not help but frowned and asked, "What do you mean by these numbers?"
"The code name of the personnel responsible for cleaning the area. Dude, these are all accountable. Just like your guards, the guards in any area have to be held accountable.
The same is true for us, which area is not cleaned, but also the responsibility of the person in charge. So please, stop affecting my work, okay? Lin Rui shook his head, made an impatient gesture, and took the notebook from the guard.
The guard can only return it to him.
But in fact, these numbers are written on it, which are some distance and bearing codes. Lin Rui used it to mark. All monitoring positions in this floor.
It's just that this way of recording can be understood by anyone besides him. And the excuse he made could not find the slightest flaw.
So he can hold the pen and notebook in a big way and record the data in front of the guard.
After half an hour, they have completed most of the cleaning work. The various situations inside the building were also generalized.
But as Zhao Jianfei said before, there are many areas they cannot enter. Because the access card on their body can only lead to most public areas or general office areas.
In some places with higher levels, they can't get in at all. Although Sergey had a way to open the door, Lin Rui felt that there was no need to take too much risk for this task of finding out.
Just as they were about to end, a guard stopped them. "Come here, come to the guard duty room."
"Boss. What to do? We don't have weapons." Sausage glanced nervously.
"Don't be nervous, they shouldn't find that we have a problem, otherwise they won't talk to us, but shoot directly." Lin Rui whispered.
As he walked to the guard, he asked, "What's the matter?"
"The duty room over there, also help us clean it." The guard replied.
"Guarding the duty room? That is not our responsibility. Besides, we don't have permission to enter that place." Lin Rui shook his head.
"It's only a few minutes, besides, I'll be watching from the side, there is no problem, just let your subordinates clean it for us.
It’s just a few minutes for you. Maybe I can ask you to sit down, smoke a cigarette, or have a cup of coffee. Come on, just do a favor. "The guard nodded towards Lin Rui.
"Well, it looks like it is 5:00, and there is still some time." Lin Rui looked at his watch and said, "Let's go, we may need to do it quickly."
"Faithful." The guard opened the duty room door with his access card. "Come in, I know, we have to clean the duty room as required.
But those guys are so lazy, no one falls when the ashtray is full. The ground was also messed up. Even I can't see it anymore, so please do me a favor. "
Lin Rui nodded and said, "It's a trivial matter. The entire building is cleaned up, and it's not bad for your room." After that, he turned his head and winked at the sausage, "You still have you, clean this place."
Several of his men skilfully picked up mops and rags and started cleaning.
The guard nodded in satisfaction, picked up the coffee pot and poured Lin Rui a cup of coffee, "Come on, take a rest. Just let the brothers do it."
Lin Rui nodded, but scanned the entire duty room.
This duty room is equipped with a large display wall. It should have been possible to see the entire building. But now the monitoring device is under maintenance, so the screen is black.
Lin Rui turned to the shelf in the back row of the duty room again. The shelf was supposed to contain guard helmets, but because of the dust, round marks were left on the shelf.
"Hey, come here and wipe this place too. This is all gray, and it's almost ready to grow potatoes. Look at the traces on this one, and wipe them all clean." Lin Rui pointed to the shelf.
"Understood, boss." Sausage took a look and immediately understood Lin Rui's intentions.
Through these traces, the number of guards can be accurately determined. If you compare it with the number of guards they found on the floor. It should be possible to know how many guards there are in areas that they cannot enter.
In addition, Lin Rui should have been able to detect more information in this duty room. Such as emergency security work and so on.
But it is stored in the computer in the duty room. During the whole process, several guards in the room were always by their side. This makes them unable to start at all.
However, cleaning a room and getting more information is a gain for Lin Rui's people. Now they can at least understand how many guards are on a floor.
How many guards are there in public areas, and how many guards are there in unexplored secret areas. This was an unexpected gain for Lin Rui and others.
So the team members quickly cleaned up the room. Lin Rui stood up and said goodbye to the guards, and returned with his team members.
Because of the delay during the so-called duty period, their time is already quite tight.
In seven or eight minutes, the monitoring equipment in the building will end maintenance and all resume work.
And this would be fatal to Lin Rui's people. The monitoring will record their faces, automatically recognize them through computers, and match them to relevant personnel for double verification.
Although the documents brought by Lin Rui and others were genuine, their faces were completely incompatible with the secret society members. Once the monitoring restarts, they will be immediately exposed.
So they must leave the building before the surveillance is restored.
But the more urgent, the more accidents happen. Lin Rui and others were stopped again at the entrance and exit. Several guards stopped them and said, "Routine inspection."
