Vault 32

Chapter 131
Their voices were full of surprise, as if they had discovered some shocking treasure.And a young man from the Marine Corps also took out the engineering shovel behind his backhand and dug a few times in the gap.The gap is full of bat guano, which has been accumulated for hundreds of years and thousands of years, almost as thick as a layer of soil. With the strength of his two arms, he quickly covered most of the gap. Dig up.

A slight wind seemed to appear because of the dug gap, picking up the dug bat guano around it and immediately dispersing the strong rancid smell.The Marines who gathered around were a little unable to bear the thousands of years of bat guano. They covered their noses and took three or four steps back before they recovered. They spit fiercely to the side a few times before lowering their heads. He cursed secretly to show his hatred for the bat.

"A vent? That's right, there is indeed air flowing through this crack in the rock!"

Carl, who graduated from the military academy as a high-achieving student, also walked over quickly, and squatted in front of the crack without hesitation, not caring about the strong rancid smell that almost made ordinary people vomit.Holding a tactical flashlight in his hand, he took a photo into the crack of the rock, and at the same time stretched his head to gaze at the space inside. After a while, he retracted his head, and hesitantly said to Liszt who came behind him: " It is indeed a vent, but the ventilation tunnel is too small."

"Too small? Let me see!"

Liszt couldn't help frowning. He looked at the rock crevice about half a meter away, and slowly stepped forward sideways, obliquely in front of Karl, and pointed the tactical flashlight in his hand at the rock crevice. , carefully observed the tunnel that could only fit a head, and the frown became more and more like a word: "It seems that even a football can't be stuffed in."

The crack in the rock seemed to have a width of about half a meter and a height of nearly two meters, but the tunnel space inside was not as big as a football.Stretching out his hand slowly, he seemed to be able to feel a gentle wind blowing by, which meant that it was indeed connected to an air vent outside.But Liszt's eyebrows were already furrowed more and more, and he asked Carl very regretfully: "Is there no way to continue to expand it?"

"Wait, expand?"

Still squatting aside, Carl, who also had regret on his face, was slightly taken aback.He subconsciously looked down at the bat feces dug out with the engineering shovel under his feet, but as if he remembered something, he took out the engineering shovel and poked lightly into the crack of the rock tentatively. The sharp edge of the engineer's shovel sank directly into the rock-like soil layer. Karl's brows stretched out, and he couldn't help shaking his head in self-deprecating way: "This is not a rock wall at all!"

The engineer shovel in his hand was pulled out slowly, and the sharp shovel still had a cold light in front of it, but under the puzzled eyes of the surrounding soldiers, Karl thrust his arms hard into the rock wall again. in the soil layer.The engineer's shovel, which had been polished and could be used as an axe, easily pierced into the soil layer of the rock wall, piercing more than half of the entire surface of the shovel, and as he raised it hard, the strong rancid smell suddenly appeared in his nostrils.

"This is...that pile of bat guano? But how is that possible!"

A member of the Marine Corps behind him also had a puzzled look on his face. He ignored the pungent sour smell and also took out his engineering shovel with his backhand and stabbed it hard into the rock crevice.Unsurprisingly, his equally sharp engineering shovel directly pierced through the rock-like soil layer, and with his strength, another large piece collapsed, causing him to stare in surprise and say: "These soil layers don't look like those sticky bat guano at all!"

"Yes, this is indeed bat guano."

But Liszt opened his mouth slowly, and carefully irradiated the bat droppings that fell to the ground because of the engineer shovel with his hand holding the tactical flashlight, but his brows were slightly frowned.But looking at the gap between the two large rock walls that were almost dug out, Liszt turned his head and glanced at the bat droppings deposited on the ground around him, but the corner of his mouth curled up a smile and said: "But the reason why these bat droppings are this color , It is estimated that it has been accumulated for hundreds of years."

This is easy to infer, because this cave should have belonged to the home of the group of bats.And the bat community in this cave has gone through many generations. It seems that the ancestors of these bats have been multiplying here since the distant ancient times, when even the Indians were just born civilization.

And as time goes by, bat feces and dead bats have accumulated in this soil layer, or in this small space, and they have accumulated more and more, and eventually formed such a The rock-like appearance also has to feel the magic of nature.Now being dug down by Liszt and the others with their engineering shovels, the essence of the fragile bat droppings is fully exposed. Although it is dark like a rock, the inside is quite soft and not half hard.

"According to the trend of this rock wall, maybe we can dig a passage leading to the upper slope!"

Carl swung the engineering shovel more diligently. Every time the sharp edge of the shovel was pushed hard, a large piece of dry bat guano would fall down, and he barely had a few minutes to follow the original appearance of the crack in the rock. , A tunnel close to half a meter was dug directly into it.However, Carl, who was still digging, stepped back two steps towards the outside, covered his nose and coughed vigorously, and said with a rather ugly face: "Damn it, the smell inside can drive people crazy!"

The surrounding Marine Corps members also had weird faces. Even if they were outside the cracks in the rock, they could still feel a rancid smell like chemical fertilizer.This is undoubtedly bat feces that have been deposited for hundreds of thousands of years. The smell made them feel that their stomachs were already overwhelmed. They couldn't help but subconsciously took a few steps back. Work in that stench.

"The quality of oxygen here, using a gas mask is estimated to cause hypoxia."

Slightly frowning, Liszt had nothing to do with this foul-smelling tunnel. He just put Winchester behind his back, took out his engineer shovel and walked over to it, vigorously removing the bat guano in the crevice of the rock. While continuing to clean up, he turned his head to the boys of the Marine Corps behind him and said, "Everyone digs for 10 minutes, taking turns one by one. Maybe we can completely dig this crack in half an hour!"
