The most important thing is that if the trapped person is in a closed environment and the oxygen is insufficient, the rescuers can also use it to supply air to the trapped person, create certain living conditions for the trapped person, and win valuable rescue time.

In this case, it took about three minutes for rescuers to insert a tube into the rubble and get a response from those trapped inside. Rescuers first sent a flashlight through this tube, then inserted a thinner tube into it, and finally connected the pipe from a small blower to the tube and began to deliver fresh oxygen to the trapped people.

And that's not all, another rescuer hung a bottle of water above the thin pipe and delivered water to the trapped people through the thin pipe. In this way, the trapped people inside can get light, drinking water and fresh air, and they will have more confidence to survive, and they will actively cooperate with the rescue workers outside.

After completing these groundwork, the rescuers began to organize the rescue work with all their might.

This type of rescue work is very difficult and risky, and it is dangerous not only for the trapped people, but also for the people outside. Therefore, the rescue action must be cautious and cautious, and it must be organized and implemented by experienced and capable rescuers.

The rescuers led the team by an experienced squad leader who seemed to have a lot of experience in this area. He chose a few slabs that looked large and were stacked on top of each other, and decided to open a breakthrough from here to carry out the rescue.

At first, Haji didn't understand much. He couldn't understand why the rescuers didn't dig from a good place, but from a place that seemed to be very difficult, and was covered with a lot of floor slabs and masonry. But after looking at it a little more, Haji understood.

It turned out that the rescue method adopted by these rescuers was to excavate the loose masonry under the slabs and erect the slabs with jacks and I-beams. To put it bluntly, the weight of the original floor slabs fell on the masonry below, and now they dig up the masonry little by little, and then carefully replace the masonry with a jack, and after digging out a certain amount of masonry below, they will replace the jack with masonry, and expand the working surface and expand the passage space under the floor slab.

In this way, the floor slabs have basically been in a stable state all the time, and there is no obvious change in the original force situation, so that the temporarily opened passage and the trapped people inside have become safe. Correspondingly, there will be no big risk to the rescuers outside.

Clever, really clever!

There is a specialization in the art industry, and these firefighters are too smart and powerful. Don't look at the progress of their excavation work a little slowly, it seems cautious and cautious, but Haji knows that everything these people do is definitely well thought out and with some certainty.

Although the progress of the excavation is a little slow, the few people trapped inside have been provided with clean water, air, and lighting, and it is believed that they should have settled down. It's just that these firefighters would never have thought that the two people they rescued were jackals, jackals who had already tasted blood.

Half an hour later, a hole more than half a meter wide and forty or fifty centimeters high appeared in the ground under the floor slabs. And since the hole has been basically dug through, the rescuers also threw a delicate shovel into it, so that the two trapped people inside can clean up the inside of the hole passage, so that they can climb out after a while.

Maybe it's because they've been trapped for a long time, and the two people inside are also in a hurry to escape. Before the rescuers could tell them that they could come out, a middle-aged man with a fat body panted and crawled out of the small passage with great difficulty.

This guy is really fat, and he wouldn't have been able to drill through this little hole if he had been in normal times. But now the situation is different, the desire for life and the fear of death make this guy desperate, even if his face is rubbed off and his expensive suit is stained with mud, he has no intention of slowing down.

As soon as ......he saw this guy come out, Haji knew by listening to his voice that it was the guy who was called the boss. It was he who had murdered one person with another man, and then he was ready to kill his own accomplices. Now that Haji sees this guy crawling out, how can he not hate the root of his teeth? Haji still regards himself as a human being in his heart, and he naturally hates this kind of murderous villain. And now he is just a search and rescue dog, and his management and expression of emotions follow the dog's way, so his expression can only be like this.

As soon as the fat man who crawled out of the rubble took a breath, he was immediately startled by Haji's scream. He flinched and stepped back until his back was against the pile of ruins that had just trapped him. Through the rescuer's light hanging from a steel bar, Haji saw a timid and vicious glint in the man's eyes. Obviously, this guy is a ruthless and selfish person, and he must not be let go like this.

"Haji, Haji, what's wrong with you, don't make trouble!" Haji shouted, and Xiao Zhang behind him immediately became nervous, pulled the leash and dragged Haji back, hugging Haji's neck and trying to comfort him. Haji knew that he couldn't break free from Xiao Zhang's control, and of course it was impossible to blindly rush over and bite this dead fat man, that would only make people think that he was a rabid dog with rabies! In the end, it must be Haji himself who was unlucky, so he was not so stupid! So under Xiao Zhang's reassurance, Haji only let out a threatening roar, but did not make a substantive attack.

"What's wrong with this search and rescue dog? Why are you so excited? Why did you offend it just now?" the rescuer looked at Haji, who was behaving abnormally, and asked the fat man with some puzzlement.

"Oh, when I was inside, I only heard the dog barking, and no one came to save us, so I scolded it. But it's okay, it's also the benefactor who saved me, and you are the benefactor who saved me, thank you, thank you!" Anyway, in his opinion, Haji is just a dog, and it doesn't matter if he hears the secret thing just now, and the dog can't speak. But how did he know that Haji was no ordinary dog.

"What about the two inside?" the rescuer asked, as the man inside had already peeked out of the hole. Seeing this, the rescue team members hurriedly asked the guy who had just shown a little bit of his head and his head was covered with blood, and asked, "How is the one inside? Can you climb out on your own? If it's okay, can you tie this rope to the man? Hey, you're still seriously injured! Forget it, you can come out first!"

The rescue team members saw that the head of the person who showed his head was full of injuries on his head and face, and he couldn't ask him for anything at the moment, so he could only let this person come out first. The fat dead man was very clever, and when he saw this, he immediately showed a kind of concern and affection, and turned to help the rescuers pull the man who was obviously struggling to climb.

Pretend to be an elephant!Haji cursed in his heart. If you're really nice to this guy in the back, how can you let him come out behind you? It's clear that you just grabbed the first one to come out, and this kid was beaten half to death by you, and he can't rob you at all, and it's good to be able to climb out by himself. Now turning his head and pretending to help, it is purely a thief's heart.

With the help of rescuers and the dead fat man, the skinny man in the back finally saw where they were trapped. But the thin man came out exhausted, and he gasped with his back against a slab, letting the sweat and mud on his face go down. The temperature inside the ruins was not low, all thanks to the fire and the power of the deflagration, and it was obvious that a series of events just now had exhausted his physical strength to the extreme.

"You hold on for a while, and then we can go together after we get the guy inside. It's still very dangerous, and if you go out on your own, you're going to go the wrong way, or you're going to make a bigger landslide, and we're all in danger. You bear with me first!" said the rescue team leader to the two dead fat men.

The two people who had just escaped did not have any dissatisfaction, whether it was the shrewd dead fat man or the thin man who was seriously injured, they all expressed their gratitude to the rescuers one after another. The dead fat man also made a look of caring for his companions, almost patting his chest and telling the rescue team that he could take care of it himself. But Haji looked at the dead fat man's spinning eyes, and knew that this guy might have something in mind!

At this time, another rescue team member took off his accessory equipment, and then got into the place where the two people were trapped just now through the narrow hole. He was going to rescue the last man, and of course that person was a corpse even if he came out. But it was his duty that he also had to risk a collapse at any moment to save that man, even if he was dead.

"How's it going?" the rescuer asked the rescuer who had already gone in through the pipe.

"No! There are no injuries on the surface, I think I have internal injuries. I tied him with a rope and withdrew. From the mouth of the cave came the muffled reply of the rescue team. Soon, the team member retreated backwards from the hole, pulling a rope in his hand. Then, the last trapped person was rescued, and of course he was dead.

"Go, get out!" The search and rescue dog takes the lead, you two follow, you two take him out, I'll break off!" ordered the rescuer at the head. Let the dead fat man and the thin man follow behind Haji and Xiao Zhang, and the other two search and rescue team members carry the bodies of the victims, and he escorts the team at the end, and then gradually withdraws from the rubble.
