Even digging a hole from the side is not realistic, because in that case, the pressure of the ventilation fan to draw air from the outside will definitely be greater than the internal pressure, and even if the ventilation fan is still working, it will only be doing useless work.

Wang Lang didn't speak, but just stood next to the ventilation fan and began to think.

After a long time, he suddenly said, "Let's go in from the side." ”

"But in that case, wouldn't the ventilation fan be useless?"

When Carat heard this, he couldn't help but say immediately.

He didn't want to die because of deoxygenation, because it was said that it was the most painful way to die, and he didn't have to experience it personally, and everyone must know very well what it was like to sit there and hold his breath to the limit.

"It doesn't matter, we can make a one-way air hole, seal the opening with fur, and then superimpose it layer by layer from the inside to our side, only the air can be out, not the air in, and it'll be fine."

Wang Lang shook his head, and then said seriously.

This is the same as the ventilation hole of the blower, as long as an inward bowl-shaped rubber is pasted, the blower can only be inlet and not out.

"But, where are we going to look for fur?"

Kalat was also a little surprised by Wang Lang's whimsy, but he couldn't help but ask.

"Those leather sofas of yours, and the billiard table, are everywhere, okay, don't talk nonsense, hurry up and dismantle them."

Wang Lang said, and he began to toss through the boxes and cabinets.

As for how to stick it on the wall, it will be easy to do when the time comes, just sprinkle some water and then use something to top it.

After making up their minds, the motivation of the two of them that had been almost worn out was re-invigorated, after all, they were blindly digging before, and they couldn't dig holes for a day or two, and instinctively people would slowly become depressed.

But now it's different, with a goal, and the two of them are already idle, so smashing the wall does have a feeling of getting twice the result with half the effort.

In this way, after a whole week, the two finally smashed a large hole in the heavy concrete wall.

The reason why it takes so long is that there is no way to do it, first of all, the tools are not good, and secondly, it happens to be attached to the solid wall of the cave, even if you smash a gap, the rest will not be very easy.

But fortunately, the concrete wall was smashed open, and the cave surface behind it was much easier, and it would not be as difficult as concrete to smash it.

After the wall was smashed open, the two of them worked together to seal the large hole in the outside with fur, and then they took a drawer as a basket for stones, and began to dig towards the ventilation fan little by little.

"Or use diesel bombs to blow it up, anyway, the stones in this cave are not very hard, and it saves effort."

Standing outside the entrance of the cave, Kalat, who was sweating profusely, was also very tired at this time, because he needed to pick up the stones taken out of it, so as long as Wang Lang didn't stop, he would naturally not be idle here.

"Bomb your sister, there is a concrete wall in it, no problem for you to be a demon, but if you dare to wave it here, God knows if you will bury yourself alive in it."

Wang Lang probed out, and then scolded directly.

"Ahem, I'll just talk about it, just talk about it."

Carat wiped the tip of her nose with a depressed face, and then said helplessly.

After speaking, he honestly exchanged jobs with Wang Lang and began to dig up.

And so it was another three days.

The two finally opened the hole and the vent completely.

As Wang Lang thought, this ventilation hole is actually part of the natural formation of the cave.

There is no trace of artificial excavation inside, it is just zigzag and leads directly to the outside.

Unfortunately, there are places where the diameter can be passed by a person, but in others, it is so narrow that it can only accommodate one leg to fit in.

But the two of them have no intention of giving up, they have come to this point, and finally have the opportunity to go out, so can they still give up?

"What are your plans for when you get out?"

Idle, Wang Lang casually asked Kalat who was waiting below while digging the cave.

Because this section is straight up, Carat is not good at it, so Wang Lang has to dig it himself.

"Get out?" Carat was stunned when he heard this, and only then did he follow: "After you said those words last time, I didn't think I could go out, and I don't know what to do when you suddenly ask like this." ”

"Okay, I'll plan it for you, you scumbag, don't run around when you go back, anyway, Shaman doesn't have the death penalty now, so you can just stay in prison until you die."

Wang Lang paused slightly, then looked at the carat below and said.

"This ...... Okay, anyway, I can't be sure that I can't get out now, I'll tell you the truth, after I get out, I know that I can't escape from the palm of your hand, so as long as you don't kill me, I will definitely have to follow you to turn myself in, but after I turn myself in, my people will definitely save me, and I won't stay in prison until I die, if you think that I only have this little bit of family background, then you are wrong. ”

Kalat thought for a moment, then said seriously.

"You don't brag about dying, can you?"

Wang Lang directly threw a stone down and scolded.

"I'm not bragging, it's true, you probably don't know it, I'm in the forces outside, not to mention the armed organization, even if it's the most powerful Tianmen among the mercenaries, you have to respect me."

Habitually dodging the stone, Kalat replied in a serious manner.

Wang Lang didn't bother to deal with the other party, no matter how capable this miscellaneous was, it didn't have much to do with him after he went out, and it was the right thing to go home to see his wife and children after the task was completed.

It's just that Wang Lang stopped talking, but Carat suddenly came to his senses, and then continued: "But then again, in fact, I don't hate you, although you have taught me many times during this time, I have also learned a lot from you, if possible, I hope that after we go out, we will become friends, best friends." ”

"Okay, don't be a sycophant, as long as you don't make trouble, don't worry that Lao Tzu will kill you for no reason, as for friends, I don't make friends with miscellaneous people, why do I make friends? We have such a big hatred, you make friends with me? Did you bully Lao Tzu for not going to elementary school? ”

Wang Lang still said casually while digging the passage.

"No, no, no, I'm not worried that you'll kill me, because I know that you are a regular soldier and won't kill people casually, and as for being sent to prison by you after you get out, it doesn't matter, because I know that I can get out, and you have taken my stronghold, I don't pay attention to it, or that sentence, my power is definitely more than this, I don't care at all."

Carat looked up at Wang Lang proudly and said.

"Damn, bragging is addictive, isn't it? Don't talk nonsense, hurry up and help. ”
