Three days ago, a serious explosion occurred in the central business district of Ningzhou City.

Three days later, another bomb was found in a residential building near the central business district of Ningzhou City.

After receiving the police information, the serious crime team, the criminal police team, including the fire department and hospital staff, immediately rushed to the scene, and at the same time contacted the explosive disposal security inspection team of the patrol special police detachment of the Ningzhou Municipal Public Security Bureau, and asked them to immediately send a bomb disposal team to support.

Time bombs, we all know about them, and they are often seen in film and television dramas.

As soon as the bomb disposal team finds the red and blue lines on the bomb and cuts it at the last second, the bomb is defused, and everyone raises their arms and shouts.

But now, it's not a film and television drama.

It's a real bomb, a bomb that can kill a person.

It was also the first time we had seen a bomb so closely.

The bomb is boxy, and although it is not so terrifying, it has brought us infinite psychological impact.

We have to think about what would have happened if the bomb had not been defused and had been detonated early.

Now, there are twenty minutes left in the countdown.

"This is a time bomb, but the procedure is very complicated, there are two ways to detonate it, the first is a countdown detonation, and the second is a mercury-triggered detonation, both of which can detonate the bomb."

The bomb disposal team went up to inspect the bomb and reported the bomb to us.

On the top of the bomb, there was a mercury anti-action device, and there was a small ball of mercury in it, which was swaying from side to side with Qi Xuehui's nervous breathing and trembling body.

As soon as the bomb is tilted and the mercury flows to one end, it will immediately detonate.

"How powerful is the bomb." I asked nervously, steady.

"There's 500 grams of TN.T in it." The bomb disposal team said seriously.

TN. T, a term that you often hear.

Everyone only knows that TN.T is the raw material for making bombs, but there may not be an accurate idea of what it looks like and how powerful it is.

TN. T: colorless or light yellow crystal, generally referred to as trinitro. Toluene.

It is a colorless or light yellow needle-like crystal, odorless, hygroscopic, explosive, one of the commonly used explosive components, with six isomers.

Trinitro. Toluene is a relatively safe explosive that can withstand impact and friction, but any sudden heat in any amount can cause an explosion. It has moderate toxicity, can be invaded through the skin, respiratory tract and digestive tract, and the main harm is chronic poisoning.

Militarily, TN. T stands for yellow explosive, which is one of the most commonly used explosives in military, industrial and mineral industries.

The energy released by a 1 gram TN.T explosion is 4184 joules.

A bullet that can penetrate a human body has 4 grams of TN.T.

A grenade that deals area damage has 50 grams of TN.T.

A rocket launcher that can penetrate a tank and blow up a wall has 500 grams of TN.T.

A heavy artillery shell that can blow up a football field has 7000 grams of TN.T.

A missile that can destroy a heavily fortified fortress has 1 ton of TN.T, and at the same time can blow up a deep crater 11 meters deep and 15 meters wide, and the shock wave generated by the explosion can knock people away and knock down people within 100 meters.

A Little Boy dropped on Hiroshima produced the equivalent of 20,000 tons of TN.T equivalent.

Now, the bomb on Qi Xuehui's body has 500 grams of TN.T, once it explodes, not only will the house not be saved, but the structure of the entire building will also change, resulting in infinite safety hazards.

"Can it be demolished?"

I looked nervously at the bomb disposal team around me and asked a question that everyone would ask, but it wouldn't get any results.

The bomb disposal team smiled and said to me, "No bomb can be 100% defused, but since the bomb is man-made, there must be a way to defuse it, let's try it." Team Qin, let all the nearby residents leave the scene and retreat to a hundred meters away. ”

As he spoke, two members of the bomb disposal team were carefully putting on explosion-proof suits for each other.

The explosion-proof suit is composed of a helmet, vest, sleeves, trousers, crotch guards, hand guards and other parts, weighing 17 kilograms, and the whole person looks very bloated.

There is a protective plate inside the explosion-proof suit, which is made of special composite materials through hot pressing of molds. When an explosion occurs, the fabric layer is crushed and damaged, which can effectively absorb the impact energy, and other factors combine to consume the impact energy of the explosion. At the same time, it can protect and achieve the purpose of intercepting fragments.

Two bomb disposal team members are putting on each other's costumes and cheering each other on. They

There was always a smile on his face, and there was no tension at all.

I stood and looked at them, and my heart was a little sour for a while.

They all look like young people in their twenties, less than thirty, and they are facing a war, and this war has only two options: life and death.

500 grams of TN.T is enough to destroy an entire room, and when the explosion occurs, especially in the center of the explosion, the explosion-proof suits they wear will not do anything at all.

The only thing to do is to leave them with a whole corpse.

They all knew this in their hearts, but they did not flinch, and resolutely walked towards the bomb.

"Team Qin, you all should withdraw too, the scene will be handed over to us." The bomb disposal team said to me through a thick helmet mask.

I pursed my lips, nodded, and let out a voice from my heart: "I am waiting for your good news, and I must come back safely." ”

We reached out our fists and bumped lightly, which is our unique way of communicating.

The room in the bathroom is cramped, the bomb has a mercury anti-activation device, there is no way to transfer it, and there is no way to use a bomb disposal robot, so it can only be dismantled manually.

Two bomb disposal team members walked towards the bathroom with a toolbox in their hands and heavy steps.

Looking at their backs, I turned and withdrew from the scene.

Outside the building, a long cordon has been set up, and the staff of the serious crime team and all departments of the criminal police team are on standby, and the evacuation of the masses has been completed, and all personnel are concentrated at a safe distance of 100 meters.

Everyone looked up at the room where Qi Xuehui was, even though everyone couldn't see the situation inside the room, they could only look at the glass window, but they still looked at it seriously.

Outside the cordon, a police command car was parked.

In the carriage, all the instruments are running, and through the cameras on the bomb disposal team, we can see everything on the scene remotely.

"Bomb disposal team, I'm Qin Mu of the Serious Crime Team, all personnel have been evacuated to a safe distance of 100 meters, over." I picked up the walkie-talkie and had a remote call with the bomb disposal team.

"Command post, this is the bomb disposal team, we are now carrying out bomb disposal work, we are going to turn off the radio, do you have any other instructions? Complete. ”

On the intercom, there was a little green voice from the young members of the bomb disposal team.

I took a deep breath and held the walkie-talkie in my hand: "Please come back safely, over." ”

"Bomb disposal team received, done, now cut off the radio."

Bomb disposal is an absolutely precise work, and there can be no interference outside the scene.

Bomb disposal is also a kind of work that relies on luck, and the transition between life and death often happens only in a second......

The bomb disposal team slowly walked to the bathroom, Qi Xuehui's breathing was more basic, and there were 15 minutes left in the countdown on the bomb.
