"Chief Lee Changmin, what is the situation now? Why didn't Captain Mu Tianyu answer? ”

In the command car on the ground, there was a tragic depression, and several commanders did not speak for a while. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Finally, the detachment leader remembered Lee Changmin, and hurriedly grabbed the walkie-talkie and shouted.

Everyone couldn't contact Mu Tianyu, and they were no longer in a hurry, but extremely panicked!

Now, everyone has a very ominous premonition: Captain Mu Tianyu has died honorably!

Lee Chang-min stood at the entrance that was already scorching hot, the floor slab had cracked and would collapse at any moment.

He heard his name being called out by headphones before he reacted quickly. He immediately wiped a handful of tears and replied sadly: "The Mu brigade is very close to the bombing point, it seems to be ...... It seems that the floor slab has collapsed in many places, and the entire Block A on the 18th floor is already a sea of smoke and fire. ”

Lee Changmin looked at the ruins inside the gate of Block A, and he had already expected that no one in it would have a chance of surviving and would be reduced to ashes.

"What seems like it? What happened to Brigade Mu? ”

When Li Changmin heard Gu Zun's voice, he cried, "Don't ask again." ”

He ripped off his headphones and shouted, "Come in with me!" ”

Liu Chengwu hurriedly grabbed Li Changmin and said, "Let me come, you keep in touch with the ground here." ”

"I'm still in touch with a fart!" Li Changmin angrily pushed Liu Chengwu away, and was about to rush into the fire.

"The energy of 1 kilogram of LPG for complete combustion is about equal to the power of 10 kilograms of TNT explosives, and the MK.II grenades of the US army in World War II only contained 56.7 grams of TNT, and the power of 10 kilograms of TNT explosives is equivalent to about 176 MK.II grenades exploding at the same time."

When Gu Zun heard the explosion, he immediately knew that it must be the explosion of the liquefied gas cylinder.

He quickly estimated that this explosion yield was equivalent to the explosion of an ordinary 8-liter liquefied gas cylinder.

If the full bottle exploded and the liquefied gas burned completely, according to the Chief Superintendent Gu, about 80 kilograms of TNT would be released.

With such power, it can even destroy a building with a bang.

Of course, Jiangqiao Science and Technology Building was designed almost 20 years ago, and it has been more than ten years since it was completed.

At that time, the design structure was certainly clumsier than it is now, but it was definitely very stable, and it would not be easily blown down, whether it was critical or not.

Although it exploded violently, the exterior wall near the explosion site was only blown open by a small hole, and some cracks appeared.

This is because the explosion just now was not an explosion that occurred when 8 liters of liquefied gas were completely combusted. Perhaps, the cylinder was not filled with 8 liters of liquefied gas.

The whole building is still firmly standing.

The fire caused by the explosion was even more intense.

The leaders of the ground command knew that their Mu Tianyu could not come back, and it was time for them to make up their minds to use powerful fire extinguishers to extinguish the fire.

Everyone is becoming more and more aware that the fire source taken by the large canteen is liquefied gas cylinders, so it is impossible for a huge canteen to have only one 8-liter cylinder, there must be a larger volume of cylinders, and there must be multiple liquefied gas cylinders.

If one more cylinder explodes, or if one cylinder explodes, who can guarantee that the other cylinders will not explode under the same environmental conditions.

If one more cylinder explodes, it may cause all possible cylinders to explode at the same time.

If there is a bigger explosion and the Jiangqiao Science and Education Building is collided, it may really be razed to the ground!

However, no one can make a decision right away.

None of them could categorically give the order to fire powerful fire extinguishers at the over-fire floor.

At present, there are still problems with the fire extinguishing agents in the fire extinguishing guns developed by countries around the world, mainly in fire extinguishing shells.

The more efficient the extinguishing agent, the greater the damage to people and equipment.

And the cannon that fires the fire is about the same as the real one, at least on the same principle.

Therefore, it is not possible to equip ordinary fire departments with cannons unless necessary.

Even if the cannon is equipped, the use of the cannon must have a considerable level of control mechanism for control and use. Just like the control of firearms, the control of cannons must be stricter.

The rest of the problem comes back to the fire extinguishing bomb.

Fire extinguishing shells can hit the fire location with relative accuracy, especially in some high-rise buildings that are difficult to climb, or special occasions. The use of fire extinguishing shells to extinguish fires is still quite effective and efficient.

However, if there are people trapped in the building, fire extinguishing bombs cannot be used lightly.

Because no matter how toxic the fire extinguishing agent is, its main fire extinguishing principle is to make the space produce an extremely anoxic state, so that the combustion can not be carried out.

The burning could not be carried out, and the trapped people inside would definitely not be able to breathe.

Besides, at present, there is no fire extinguishing agent that can be completely non-toxic. If there are trapped people inside, not only can they not breathe, but they will also be poisoned and destroy human organs.

In other words, the premise of firing a powerful fire extinguisher can only be after confirming that there are no signs of life in the fire scene. Except for this situation, no one dares to make up their minds to fire a powerful fire extinguisher now.

Judging from the current situation, there are no signs of life on the entire 18th floor.

Not only will the explosion just now be so violent, but the fire and smoke will be even more severe and violent, and all life will be wiped out.

Theoretically, a powerful fire extinguisher should be fired into the building as soon as possible.

However, all the people were unwilling to accept the fact that Mu Tianyu and a trapped person had been hiding in the explosion at the fire scene psychologically.

All of them want further confirmation. Before there is no confirmation, no one is willing to recognize that their hero Mu Tianyu has been sacrificed!

Yuta Yuta cried at this time, grabbed the general manager who had seen him in this building, lifted his collar and cried and asked, "Is there any liquefied gas cylinder in the building?" ”

Hearing this sudden cry, people seemed to sober up a little, and hurriedly came over and asked, "Tell me quickly, are there any cylinders?" ”

At this time, everyone's psychology is very longing, and the two words that the general manager can say are: "No." ”

Then, at this fateful moment, the general manager collapsed to the ground all at once, his mouth began to tremble, and the tip of his tongue was stiff.

But the next moment, he still spat out a few words: "There are also 4 cylinders of 25 liters." ”

Hearing this answer, Yuta Yuta was no longer able to hold on to the man's collar, and he collapsed.

Jin Chen, who had just rushed over, was also full of tears in his eyes, standing there stupidly, and he couldn't support his body a little.

He tried to go up and pick up Yuta Amada, but he collapsed himself.

He couldn't control it anymore, hugged Yuta Yuta, and only shouted: "Xiaoyu......!" ”
