And around here... there is nothing to see.

It's the subway.

For ordinary office workers, this place is a very familiar place. Every day, you have to squeeze in. Once you close your eyes, you can automatically build a subway station structure in your mind.

Now, the cordon has been opened, and the passengers have also sat back. Some people have cast curious eyes at the police, and there are some whispers in the crowd.

Zhou Yan seemed to suddenly think of something.

Because he saw it on the door next to the ladder, the words [12] were written.

This [12] is actually not written on the train, but on the baffle of the subway platform.

I believe that people who often take the subway know how this [block] works.

But for the sake of security, I still need to explain it.

Generally, platform baffles are made of tempered plastic and are transparent, but on the baffles, there are actually doors.

When the train stops, the train's [door] will automatically correspond to the platform baffle.

If a person wants to enter a train, he must first step over the door of the baffle and then the door of the subway so that he can enter the car.

At this moment, the subway door in front of Zhou Yan slowly closed, and with a long sound, the subway drove away, leaving only a transparent baffle and the [12] mark on the baffle door.

"Can you be sure that the bag that contained the money was placed above Door No. 12?" Zhou Yan asked suddenly.

The plainclothes policeman who was staring at Mrs. Qian at the time nodded: "Of course I can be sure."

"Well... Then, can you be sure that the corresponding carriage at the door 12 of the previous platform and the corresponding carriage at the same carriage at the No. 12 of this platform?"

"Ah?" The plainclothes policeman was stunned: "Uh, I didn't understand much."

"That is to say, will the train stopping locations be different in two stations? I saw a subway station that was obviously a bit old, and this subway station seems to be new.

So will the lengths of the two new and old subway stations be different? Will the carriage corresponding to the gate 12 of the previous subway station reach this platform? The corresponding carriage will become the gate 17."

"This..." After hearing Zhou Yan's words, Lao Guo seemed to frown: "Brother Zhou means, could it be the travel bag with money that is actually placed on other cars?"

"It's just an idea." Zhou Yan nodded.

"Hiss~" Old Zhou was also stunned. Everyone has been to the subway, but he really doesn't know whether the doors of the new subway and the old subway correspond one by one.

Perhaps, the subway had 18 cars more than ten years ago, but now the subway has 20 cars?

Does the subway door correspond one by one?

As a member of the Crime Squad, he never considered this issue. For a moment, Lao Guo felt that he still didn't seem professional enough.

But he didn't know it didn't matter, wasn't there a subway staff next to him?

Lao Guo immediately called a staff member to come and ask.

The staff's answers were much more professional, and they said a lot.

To sum up, there are only three types of subways in total, and the subways on the same route must be of the same type. The doors corresponding to the subway station are all one by one, and there will be no situation described by Zhou Yan.

After hearing this, Zhou Yan nodded.

"Well... the carriage and the door correspond one by one... When driving, there is no possibility of people in the car going out, and the station is always being monitored by the police. In this way, no matter what you want to do, you can only take the train to enter the subway tunnel."

Zhou Yan thought, and looked at the dark subway tunnel through the baffle of the platform...

What happened in that dark ball...?

......

According to this idea, the best way is to ask the subway responsible unit to block the subway line, and then send a group of policemen into the tunnel and search it in a little bit by bit.

But unfortunately, this is impossible.

If there is really a den of trafficking in this subway, maybe the subway can be blocked for a while, but if you say that it is to let the subway stop running in order to understand the mystery of the "mystery of money being transferred", it would be a bit unreasonable.

If you have been out of service for one day, maybe you will have to pay a lot of subway tickets. Who will pay the money then?

Even if the money is thrown away, the public opinion cannot withstand it. Why? If a rich man loses five million, you will stop the subway?

Then, if we workers work late for night shifts, you will not care about the salary deducted?

It was a matter of storm in minutes.

Therefore, the case at this moment has suddenly reached the point where it cannot continue.

In desperation, the police could only be very depressed and suggested, "Let's go back. If the money is really obtained by the kidnappers, he will definitely call him."

And this suggestion is really hard for the detectives to accept, because it is equivalent to saying, "Then~ these two detectives have no tricks, so we can only be led by the kidnappers."

Zhao Shengrui had a stern face, but he was also helpless because he really couldn't explain this matter.

As for Zhou Yan... his brain fatigue seems to have been relieved little by little, and his thoughts are gradually becoming active. In his memory, Mr. Qian's various behaviors, Mr. Qian's reaction, the attitude of the police towards the kidnapping case, and the entire process of paying ransoms later were no longer a pool of stagnant water. Instead, it flowed slowly, gathered into a stream, flowing in his mind with a cold feeling, getting faster and faster.

"Okay~ Let's go back, as long as Duoduo is fine." Mrs. Qian still didn't want to care about where the 5 million went. She was still as always, just caring about the safety of her children.

For... it is normal for a mother to only care about the safety of her children.

Zhou Yan was suddenly stunned.

He seemed to have grabbed something at once...
