Upon hearing the news, Nan Chi Sheng quickly brought more than a dozen well-trained police elites to join us.

"Director Nan, the general situation has been controlled by us now, but according to the kidnappers, they brought a black backpack when they came in, and it is not clear what is in it for the time being."

Nan Chisheng was also a little surprised when he heard me say this, but he didn't dare to be careless while being surprised.

He looked at the time and said to us: "There are still two hours before the three hours agreed with Zhao Wujiu, we still have plenty of time to plan the next move, just now I reported the situation to my superiors, and now I have sent people to look for Zhao Wujiu's whereabouts in the surrounding area." ”

Hua Yu said: "Our first task now is to determine one thing, whether the kidnappers brought in the bomb or not, if it is, then our rescue operation will be deadlocked." ”

In fact, everyone understands this in their hearts, and the reason for not saying it is so that they don't have to be too nervous to be there.

Nan Chi Sheng walked up to the kidnappers we captured and asked, "What does the backpack you brought look like?" ”

Two kidnappers, look at me, I'll look at you, and one of the slightly thinner men said, "It's like a normal travel bag." ”

Then, Hua Yu called up the surveillance video of the eleven kidnappers entering the Kuohai Building.

As can be seen from the video, the gang infiltrated the building during the rush hour of work, and they all had the pass to the building in their hands, so they were not checked by the security personnel when they entered.

And the travel bag they said also came in with them when they passed through the security equipment.

Nan Chisheng looked at the surveillance video and said: "If it is really a bomb, it is impossible for the instrument not to check it, if it is a knife, it is possible to bring it in, but I think the bomb is still not very reliable." ”

I said, "Could it be a plastic bomb or something?" ”

As soon as I said this, everyone was surprised, if it was a plastic bomb, it was really possible.

Plastic bombs, in fact, are no strangers to many people, this kind of bomb is what we usually call the game used, commonly known as plastic bombs.

Its main ingredient is polyisobutylene, which is made of gunpowder mixed with plastic, which is extremely powerful.

Because this kind of plastic bomb can be hidden in many inconspicuous positions, as long as it is used with chewing gum and other sticky things, it can be sticked, so it is quite convenient to use.

"There is also this possibility, as long as the chemical product of polyisobutylene is carried in batches, the instrument may not be able to detect it, and gunpowder, as long as it is well hidden, it is also possible, but the amount is too large to enter at all."

Nan Chi Sheng also had doubts about the authenticity of whether there was a bomb inside at this time.

Hua Yu said: "This kind of plastic bomb, can be timed, can also be remote control, I am thinking, if Zhao Wujiu is really nearby, then he must have something like a remote control in his hand, and this distance must be connected with the signal of the bomb, as long as the situation is not right, Zhao Wujiu must press the remote control at the first time, we still don't know the power of the bomb in their hands, but the power of the general plastic bomb is not small, if the amount is larger, a floor can be blown up." ”

I smiled and said: "That's not simple, the signal source of this plastic bomb is different from the mobile phone and computer, as long as you check the signal source of two kilometers around here, don't you know Zhao Wujiu's location very clearly?" ”

"Makes sense." Nan Chi Sheng's face also softened a little, and according to our analysis, we quickly arranged the following explosion search team to start the detection of the surrounding signal sources.

We can't help anything at the moment, and we can only wait for the reply of the explosive search team before proceeding with the next rescue operation.

Although this kind of signal source is very special, the range is too large to detect a special signal in a short time.

At this point, we must calm down, and only after we find Zhao Wujiu's traces and successfully arrest him, can we do it.

We waited for the results while monitoring the situation upstairs.

After a while, the seven kidnappers, who were supposed to be watching the hostages outside, actually left the four of them and entered the room where the door had been opened earlier.

And when they entered, they locked the door directly, and they couldn't see what they were doing inside.

My mind is now tense to the extreme, and any wind and grass will be a great test for me.

And in the central control room, Hua Yu and Nan Chi Sheng were almost exactly the same as me.

Nan Chi Sheng said in a deep voice: "It seems that they are going to plan something very important. ”

Hua Yu and I didn't speak, but it doesn't mean that we didn't hear it, but what they were going to plan, whether it would have something to do with Zhao Wujiu, we don't know everything.

The work of the explosive search team is still going on intensely, and I am afraid that it will not be able to reply to the message for a while.

I waited a little impatiently, and said to Nan Chisheng: "Director Nan, we can't wait like this any longer, we must start as soon as possible, it won't do us much good if we do it like this." ”

Nan Chi Sheng said with a gloomy expression: "Who doesn't want to do it as soon as possible, you have also seen the current situation, we can only wait, we will not have a chance if we don't wait." ”

I waved my hand and said, "No, I don't mean assault, but arrangement." ”

"Arrangement?" Hua Yu didn't seem to understand what I meant, and looked at me suspiciously,

Nan Chi Sheng was the same, and said to me, "Then what kind of arrangement? ”

I walked to the monitoring screen, pointed to the range of the monitoring and said: "You look at the outside, it is a half-wall made of tempered glass, we can use the blasting method to forcibly break through, and in the area of the room, there should also be such glass, we might as well attack at both ends, while the kidnappers are gathered together, let's control the scene first, what do you think?" ”

Nan Chisheng touched his chin, thought about it again, and said very cautiously: "Your method is not impossible, but there is one thing we are not sure about, that is, whether the kidnappers upstairs have a real-time call with Zhao Wujiu, if not, then no problem, if there is, then our actions will definitely be known by Zhao Wujiu, when the time comes, he jumped over the wall in a hurry and directly detonated the bomb, and none of the people present will survive." ”

That said, it throws the problem back to the beginning.

I couldn't help but smile bitterly in my heart, I had never encountered such a case before, and this could be regarded as a disadvantage.

Although he couldn't attack it, Nan Chi Sheng still felt that it was necessary to do so, so he first arranged for someone to place small blasters on the glass at both ends.

Why can't we attack directly, in fact, we can completely assault, not only can we catch the kidnappers inside by surprise, but also successfully rescue the hostages.

But there was one thing I didn't expect, and this is what Hua Yu reminded me next.

She said to me: "If Zhao Wujiu really has a bomb remote control in his hand, then the first thing we will do after we enter is to cut off the communication equipment inside, but as Director Nan said, if the kidnappers and Zhao Wujiu are really talking in real time, then they must be in contact, if such a call is interrupted, Zhao Wujiu will definitely take the first step, then the action to arrest Zhao Wujiu may have to be temporarily put on hold." ”
