Vault 32

Chapter 132 Shocking News
The most critical point why a gas mask can protect against respiratory poisonous gas is to be able to filter the air.The layers of filters in the gas mask can intercept any non-oxygen particles, so as to ensure that the human body can breathe air correctly.But in the process of filtering, even part of the oxygen will be blocked, and it will be caught in some kind of environment that causes hypoxia.

Liszt and the members of the Marine Corps are quite aware of this, especially in this cave with insufficient oxygen, using a gas mask is probably not anti-odor, but a kind of torture.He just took out the towel in his backpack, folded it into a simple triangular towel, poured water on it, covered his mouth and nose, held his breath, and swung the engineering shovel vigorously, as if he wanted to hit the ground in the shortest possible time. It is the same as digging all the cracks in this rock within a short period of time.

In fact, the progress of the project is extremely fast. With the rapid excavation of more than 20 people, they have already penetrated into this tunnel for a distance of more than 20 meters.Especially the rock crevice tunnel that seems to be winding and digging upwards obliquely. It is known that the opening on the outside of the mountain should be in the area halfway up the mountain.

But now it is no longer a person digging in front alone, because the excavated bat feces have filled the bottom of the rock cracks, and someone must quickly clean the back with an engineer shovel to maintain the less than half a meter wide tunnel. Will not be re-clogged by bat guano dug up above.Even in the cave, there are more than a dozen piles of bat guano excavated from the cracks in the rock. If it is not cleaned up, it is estimated that it is a joke to want to live in the future.

As they dug, the Marine Corps member at the front narrowed his eyes slightly.After digging through a slight turn, his eyes have already seen a little light in the football-sized air vent in front of him, which made him widen his eyes, and said loudly toward the back: " Hey, just ahead, I see the sun appearing ahead!"

As he spoke, he quickly exerted force, and large pieces of bat droppings quickly collapsed and fell off with the sharpness of the engineer's shovel.And the sunlight in front of his eyes became more and more clear, even according to his calculations, as long as they dig hard for a few minutes, at a distance of about four or five meters, they will be able to recreate the rock crevice that was completely buried in bat feces. Open up a path to the outside world!

"Very well, our plan is right!"

Liszt also clenched the engineering shovel in his hand, slowly straightened up beside the dozens of piles of bat droppings, and looked at the Marine Corps soldiers who were also busy around him, with a smile on his face .Turning his head to Carl, who was looking at him in the same way, he couldn't help but nodded and said: "As long as we can open up a new tunnel, then the ventilation problem in this cave can be solved!"

"Solving the ventilation problem is only the first step. We still have piles of bat guano to clean up, especially now it seems that this is not a small amount of work."

Nodding his head slowly, Karl also gently straightened his waist, bending over and working for nearly half an hour, which made his spine a little tired.Rubbing his back vigorously, he looked at the dozens of piles of bat droppings in front of him, and swept the tactical flashlight in his hand towards the entire interior of the cave, but there was a wry smile on his face: "And on the ground in most areas, we The bat guano hasn't been cleaned up yet, and if nothing else, we'll need a week's worth of work to get it all done."

"A week? No, it's too long."

Liszt also frowned slightly. He turned around and looked at the dozens of piles of bat guano inside. These were just taken out of the rock wall tunnel. Adding to the cave floor of more than 1000 square meters, there are probably more than a dozen more. Heaps are fine.Sighing slowly, Liszt inserted the engineer shovel into the one-meter-high pile of bat guano next to him, nodded slowly and said, "It's time to add more manpower."

It would be impossible to completely clean a cave of more than 1000 meters without even a week.Besides, the more than 20 of them are not robots. If they want to clean and take care of things every night, they simply can't stay in this cave with a strong putrid smell.Especially looking at the huge cave space, Liszt thought about it in his mind and said to Karl: "Continue to recruit 20 people to form a platoon-level unit. 40 people will take turns to clean up, which should shorten a lot of time."

"Captain Liszt, we have already dug through this crack in the rock!"

A cheer of surprise appeared in the cave, which immediately interrupted the conversation between Liszt and Carl.In the half-meter-wide crevice of the karst cave, the soldier with a towel tied to his nose and mouth slipped down carefully and took a deep breath, but the still strong rancid smell made him cough instantly, and at the same time He waved to Liszt: "This rock tunnel is above a cliff, and you can even see the entrance of the karst cave we came from more than 500 meters away!"

"What?" Liszt raised his eyebrows slightly, and immediately walked quickly towards the crack in the rock, and at the same time, Karl behind him also followed quickly.The cool breeze also seemed to appear in the tunnel in the rock crevice, blowing and dispelling a bit of the rancid smell.And he stepped forward quickly, directly climbed up the winding tunnel along the slant above, and walked towards the glimmer of light at the top with big strides.

This tunnel is not crowded either, it is basically half a meter wide and more than two meters high, like a raised eye.And Liszt quickly stepped up in this tunnel, and after climbing a few high slopes of about 70 degrees, there was an obvious light in the tunnel in front of him, even the tactical flashlight in his hand could not hide it.

"This cave really has another exit!"

And the freshness of the air has completely dispelled the rotten smell of bat feces. Liszt walked quickly towards the light, and couldn't help but narrow his eyes slightly. When he gradually got used to the light, he slowly Slowly opened his eyes, looked at the lush virgin forest of the Rocky Mountains outside, and the blue sky and white clouds, couldn't help but took a deep breath: "It really came out!"

But a strange sound made Liszt's ears move slightly involuntarily, but he raised his head instantly, and a dense stream of data burst out from his two pairs of eyes, and in the middle of the blue sky and white clouds, A U.S. Federation F-15 fighter jet is roaring towards the distance, and its extremely fast speed has already drawn a long line in the clouds.But it is definitely not a normal cruise, because just behind its buttocks, two Soviet MiG-25s are fighting, biting tightly behind, and launching an attack posture from top to bottom!
