It's not that Bai Song's memory is really so good, but that he was a little precautionary about this matter last time.

Over the years, he has been to the hospital many times and has never seen a male elevator operator. The main reason is that this profession is indeed not a high-paying occupation, and it is almost exclusively done by some women with no special skills.

Last time, he looked at this person more.

And this time, fortunately, they did a little disguise, although the two didn't know why the leaders of this hospital were waiting for them in the elevator, but it was foreseeable that last time, the enemy was dark and I was clear, and it was likely that what the two of them did was watched.

The main reason is that the behavior of the two of them last time looked "very police", and they looked everywhere, and it was inevitable that they would be noticed.

Fortunately, there was a gap of two months between these two visits, and if they came once at that time and came again the next day, it is estimated that they can be recognized even if they change cars and put on makeup, after all, Bai Song's height is a bit difficult to hide.

"Last time, when do you think we were targeted?" Liu Shuyuan reconfirmed that there were no electronic devices such as surveillance video in the corridor on the first floor, "Is it when we go to the library?"

"It could be, it could be earlier, but it doesn't matter. Bai Song said: "Last time we drove a unit car. ”

Liu Shuyuan was silent for a few seconds, and no longer asked the question: "Is there monitoring in this corridor?"

"There is definitely no floor below, but the floor above is uncertain, it's too dark. Bai Song said: "Let's take the elevator to the 13th floor to play for a while." ”

"Okay, stay in good shape. Liu Shuyuan quickly entered the play.

The elevators are all occupied, and there are still several people waiting for the elevator at this time, which is a rare time for the hospital to be busy.

Listening to the people waiting for the elevator chatting, I also heard a little thing, this fight is a group fight, there are many minor injuries and minor injuries, and two people are seriously injured, one was pulled away by other hospitals, and the other is being rescued here.

To say that this kind of thing is not common, the nature is very bad, and the police are constantly being dispatched here, and some of the younger brothers who are not injured are surrounded by the police to take notes.

One person came out this time, and it is estimated that more than a dozen people will go in.

It's rare to be so lively, waiting for more and more elevators, and after the next wave of elevators came down, more than a dozen people entered the elevator.

"Fifth floor. ”

"Sixth floor. ”

"Seventh floor. ”

"Thirteenth floor. ”

Everyone reported the floor one after another.

The female elevator attendant pressed them one by one and maintained the order in the elevator.

The person was a little crowded, Bai Song faced the camera sideways, blocking Liu Shuyuan, and Liu Shuyuan quietly stretched out his hand and pressed "10".

No one noticed the situation until more than half of the people got off the elevator from the sixth floor, and the elevator attendant didn't notice it.

The elevator continued to go up, and the elevator clerk's face changed, and he wanted to cancel the 10th floor, but found that this button did not cancel this function at all.

The elevator operator didn't encounter this situation, and it took me several times to find that this was not possible.

The people on the seventh floor went down, the elevator door closed, and the elevator man realized that it was too late.

Generally speaking, if you press the wrong elevator number, the central control side can also be canceled. For example, the elevator attendant can make the elevator stop on the seventh floor and then call the central control.

But now that it has begun to rise, it is only a matter of seconds to reach the tenth floor, and it is too late to do anything now.

These people who go to the thirteenth floor often go upstairs to exercise or read books, and they don't know how many times they have taken the elevator, but no one has ever stopped on the 10th floor, so everyone is a little curious and wants to see what the situation is on the tenth floor.

I have to say that curiosity is a common trait of human beings.

Originally, the two of them planned to hide their curiosity, but several uncles and uncles were about to stick their heads to the elevator door, and the two of them also showed some curiosity just right.

The upward procedure of the elevator was inevitable, and soon the elevator stopped steadily on the tenth floor.

The elevator door slowly opened, and Bai Song saw that there was a wall about a meter away from the elevator outside, and there was a wooden door on the wall and locked.

This caused two or three people to stick out their heads to look, and the elevator man hurriedly stopped: "This floor is a laboratory, there is a virus, and it is usually not open!"

As soon as several people heard the word virus, they immediately retracted their heads and pressed their bodies against the inner wall of the elevator.

The two also learned from everyone, from the curiosity at the beginning to the distance after hearing the word virus, and the appearance was okay.

The wall looks like it's been under construction for a while, and it's barely visible because of the dim light, but Bai Matsu can tell that no one has been here for a long time.

The door closed slowly, and the smell of yin and tide in the corridor entered everyone's noses, and several uncles covered their mouths and noses one after another, for fear of inhaling the virus.

Bai Song and the others also pretended to cover their mouths and noses, but they didn't really cover them, mainly because the elevator staff didn't make any moves, indicating that there must be no problem.

This smell is not strange, Bai Song has smelled this smell many times, especially when he was out of the police station before.

It's the musty smell of dark, damp and dark that hasn't seen sunlight for a long time.

It stands to reason that this is a laboratory, so it should smell like formalin...

After the door closed, the elevator continued to go up, and Bai Song keenly saw that the elevator attendant looked at the elevator surveillance camera with some concern, probably sighing that he was going to be fined chicken legs.

Although these people's salaries are not high, Bai Song is not embarrassed to be fined for this, after all, these people still know some things, but they don't know much.

There was nothing extra to discover on the 10th floor, and soon, the elevator went to the 13th floor.

The people in the elevator left the elevator like a run, and by the way, they fluttered and fluttered the "virus" on their bodies, for fear of being contaminated a little, and two people looked at the elevator number carefully, probably wanting to avoid this elevator when they went down for a while.

People of this age are particularly superstitious about words like radiation and viruses.

The main reason for superstition is that they don't understand it.

This is a very strange thing, the more you don't understand it, the more you believe it.

There is a classic saying: everything sold on the market, but everything that can't be solved by middle school knowledge is all a lie.

Therefore, the radiation of microwave ovens, mobile phones, televisions, and radio stations is harmful to the human body, which has become the consensus of most middle-aged and elderly people, although this is indeed false!

Only some ultraviolet rays, X-rays and gamma rays with wavelengths shorter than 150 nanometers have ionizing radiation that is harmful to the human body.

The two of them also learned the movements of a few old people, fluttered a little, and then went to the vicinity of the activity room.
