But to his disappointment, only noise came from the communicator. Although the communicator indicated that the call was still in progress, Lin Rui did not know that the black mamba had received his message.

"Do you think they received it there?" Lin Rui asked, turning his head.

"From the current signal situation, it is really hard to say. Although the communicator seems to be connected. But it is very likely that the sound signal we send is accompanied by a lot of interference.

If this is the case, for them, perhaps all they hear is a murmur. "Sausage replied.

"Damn it. Then can we cut off the communication and reconnect again?" Lin Rui asked.

"Yes. But we can't guarantee that we will be able to connect. Maybe this is our only chance. If we hang up, then we won't be able to connect again.

We may have wasted the only opportunity. If it's me, it's best to keep the communication signal and keep repeating it. This way they have a higher probability of receiving our information. "Sausage replied.

Before he finished speaking, the blue light on the communicator flickered twice and then turned green again.

This means that the communication signal is over and the communicator is offline, possibly because their own signal is not good. It is also possible that the other party could not receive it and hung up.

Everyone is in a heavy heart. They have no idea whether they have contacted the Black Mamba.

If contacted means they can get out of trouble, if the black mamba does not receive their distress signal. Things may be bad.

"Well, I don't think we need to be so pessimistic. Maybe the black Mamba has already received a signal, so he closed the communication." Sergey shrugged.

"If he receives our request for help. Maybe he won't hang up the communication in such a hurry, but will ask for more detailed information." Yelena shook her head.

"Perhaps he felt that there was a problem with the communication equipment, and the noise was too loud, and I couldn't get any results when asking in detail. Maybe he had already rushed over with someone." Sergey was a little embarrassed. "I just want to keep everyone optimistic.

But it's not bad, that Aguero just trapped us, but didn't force us to death. If I were him, I would block the ventilation duct.

Under the condition that the air cannot circulate, we hold on for a few hours at most. Will be suffocated here. Compared to this result, we are already very..." Before Sergey had finished speaking, the green light on the communicator suddenly changed to red.

"There is no signal again, what's the matter?" Lin Rui frowned.

"Damn Russell, you really are a crow's mouth. Our communicator antenna came out of the ventilation duct.

Now it looks like Aguero has blocked the ventilation duct. Although the space in this place is large enough, the stored air is also limited.

The few of us are breathing every minute and consuming oxygen every minute. Like you said, we only have one hour left. "Sausage leaned against the corner wearily.

Sergey wanted to give himself a mouth. Good things are not working, bad things are working. He just said casually, Aguero outside really did that.

Although they were trapped, they only relied on a narrow 15-centimeter pipeline to supply oxygen. But at least it will survive for a while.

Now that even the fifteen-centimeter vent has been closed, they have truly come to an end.

Now all their hope lies in the black mamba. As for the Black Mamba, I don't know if they have received their distress signal.

Lin Rui felt terrible. He hadn't felt so powerless for a long time. When the situation is not under his control at all and can only watch everything develop. This sense of powerlessness and helplessness came so strong.

"I'm sorry, everyone. It hurts you." Gonzalez looked at them.

"Shut your stinky mouth, talking will speed up oxygen consumption." Lin Rui said coldly, "Everyone sits against the wall. Try not to talk and keep breathing steady.

The lower the posture, the greater the concentration of oxygen in the air. Sausage, how much dynamite do you have? "

"Blasting walls and iron gates will definitely not work, and I have already said that doing so will kill us all. In such a confined space, an explosion will break our internal organs by the shock wave." Sausage shook his head. .

"I'm not talking about this. In a confined space, explosions will produce a lot of gas. If we block this side of the vent, and then pass a small explosion, can the explosion gas reopen and be blocked outside? Vents?" Lin Rui asked, turning around.

"I don't understand too much." Sausage frowned.

"The ventilation pipe here uses 15 cm steel pipe embedded parts, which means that if the two ends are blocked, the ventilation pipe itself should be a confined space.

If an explosion is completed in the pipeline, will the thrust generated by the gunpowder gas blast away the blocked end?

It is similar to the principle that a bullet is propelled by the gas of the propellant and shoots out of the barrel. "Lin Rui asked.

Sausage froze for a moment, "It is possible. But we have to make sure that our end will not be blown away by the explosion, but will be completely sealed. Only then can it cause the kind of effect you said.

If we can seal the side close to us, it would be possible to do so. Because in this case, Aguero's method of sealing the outside ventilation ducts would not be too clever.

In such a short period of time, it is impossible for him to use any firm method to seal the pipeline. At most, only use a cloth ball to soak in water and stuff it into the pipe to block air circulation.

If the blockage on our side is tight enough, the gas generated after the explosion will form an explosive impact, which will advance along the pipeline, and finally push out the cloth block blocking the pipeline.

But the problem is that we have to be sealed. "

Lin Rui nodded, "Fold the tarps to cover the vents, then find the wooden planks to hold them down, and then use the sturdy table legs to support them.

To ensure that the vent at our end can be completely blocked. Then make a few small powerful explosives and throw them in through the vents. Then block the vents.

Use the impact of the explosion to flush out the outer seal. "

"It's interesting, it's worth trying." Nightingale nodded, and a few people came to the court to help.

They found tarpaulin to use as a cushion. I found a wooden board and tried to hold it firmly against the vent.

As for the sausage, he carefully disassembled his C4 bomb, divided it into small pieces, and plugged in a mini detonator.

After everything is ready. Everyone walked aside. The sausage connects the mini-detonator and the small C4 bomb and puts it into the ventilation duct.

Then block the ventilation ducts, reinforce them with tarps and wooden boards to ensure airtightness, and support them with metal table legs.
