"Boom-"

The deafening sound seemed to pierce the eardrums, and everyone in the cave subconsciously covered their ears in order to barely resist the terrifying sound waves. A strong air flow swept through the entire cave tunnel, and even the bat droppings in the cave were lifted up in a layer, covering the sky as if it was raining, with that unpleasant stench and extremely disgusting.

But no one cared about these small dots splashed on their bodies, and when the dust and mud rushed back to the ground with the air current, the group of marines took away their hands covering their ears, but the buzzing tinnitus still made them unable to hear the sound for a while, and shook their heads vigorously before standing up crookedly against the rock wall next to them.

At the entrance of the mountainside of this cave, a full two kilograms of industrial explosives have lifted the entire soil layer on the mountainside. The terrifying force had even damaged the structure of the mountain outside, and a huge amount of earth and rock had been buried, and the tunnel near the entrance had collapsed tightly. Not to mention using manpower, even if you dig with tools such as excavators, I am afraid that you will not be able to dig for a few hours.

Liszt also shook his head vigorously, even his physique could not withstand the loud noise caused by the explosion, and he plucked the inside of his ear with his fingers, and after slowing down for three or five seconds, he exhaled a long breath, smelling the increasingly rich rancid smell between his noses, he couldn't help but spit to the side, and said slowly: "It seems that there is more explosives." ”

But none of the surrounding soldiers heard him, for the subtle but dense hum still ringed in their ears. Even Carl, who was beside him, rubbed his temples with his hands, turned on the tactical flashlight with an extremely ugly face, turned his head to look at the soldiers around him by this light, and opened his mouth but couldn't say anything.

The organs inside the ear are undoubtedly fragile. And when the huge explosion swept through the cave, everyone's ears were already shocked. Even Liszt had to nod, stretched out his hand to make a tactical move towards them, and at the same time opened his mouth and said with his mouth: "Rest in place, five minutes." ”

"Roger." The surrounding marines also made an OK move. All nodded and slowly stood up against the rock wall, or supported each other, pressing their fingers on their temples and ears. The entrance had been blocked, and their eager hearts had gradually settled down, and they had their hearing restored.

The light of the tactical flashlight has also been fully turned on, and almost more than forty light sources illuminate the rock wall at the top, which also makes the scenery in this cave appear in front of everyone. And Liszt took a slow breath, and there was a certain stuffiness in the thick stench, and he turned his head to look at the more than forty people. The appearance that this karst cave was already crowded, and he couldn't help frowning: "Now there is only one vent left, and the oxygen is estimated to not last long." ”

It is impossible for them to survive in this oppressive and stuffy enclosed space for long, especially since the ground is still full of filthy bat droppings, and even if they stay here for a week, it is estimated that all of them will fall ill and lose their personnel. Although there are no deaths, mental illness or bacterial infections and other illnesses will definitely appear in the more than 40 Marines.

These are living beings with true personalities. Living with his own emotions, even if he has been unconditionally loyal to Liszt. But they can still die, get sick, make mistakes and even be impulsive. They also need food, a clean living environment, and even good love, although most of them are bachelors these days.

"Maybe they lived in a past life. You can go to the second bar to mix, and you will definitely be able to mix well with that group of. ”

Touching the tip of his nose, Liszt was also bitter. The buzzing in his ears had subsided considerably, and he walked towards the crevice he had found before, taking advantage of the light of the tactical flashlight around him. Liszt squatted slightly at the bottom of the rock wall, looking at the narrow rock crack that could barely fit a person in, less than forty centimeters, and couldn't help frowning: "This is really small." ”

The crevice is quite small, just behind an inconspicuous bulge in the interior of the cave, and if you don't come and search carefully, you won't find a small cave tunnel here. But Liszt squatted on the side of the rock wall, but he subconsciously plucked his ears with his fingers, and the humming sound caused by the violent explosion gradually dissipated, and his hearing returned to his ears.

"The sound of flowing water?"

Holding his breath slowly, Liszt's ears moved slightly, and his whole body slowly approached the mouth of the cave, but his brows were already tightly furrowed. He glanced at the gathered Marines around him, but handed Winchester in his hand to Carl, who was following him, and he simply climbed into the narrow cave tunnel with his whole body propped up.

As the cave tunnel went deeper and deeper, Liszt could feel that there was no way to move around in this narrow space. But his keen sense of hearing has also played a great role, his teeth gritted the tactical flashlight in his mouth, he looked at the slightly curved narrow tunnel in front of him, the sound of water in his ears has also become clear, probably crawling less than ten meters downward, the light source in his mouth has also made his eyes see a more huge space!

"Here... Is it really a group of karst caves? ”

Wheezing deeply, Liszt's breathing was quite smooth, and there was even a feeling of fresh air between his mouth and nose. His brows furrowed slightly, he took his tactical flashlight to adjust to the long-range shooting mode, swept the huge karst cave around him, his eyes were already narrowed, and he couldn't help but gasp and said, "So big?!" ”

In his eyes, this karst cave was almost four or five times larger than the one just now, and it looked like it was already more than 5,000 square meters. And he took a few steps forward, and at the end of the light, the sound of water was clearly in his ears. It was a dark river that flowed slowly in the low-lying part of the cave here, and although the sound was not loud, it was already ringing in the cave.

The corners of Liszt's mouth curled into a smile, he looked at Carl and the other marines who were also crawling in the tunnel behind him, and shouted into the cave tunnel: "Everyone get here, the last guy remember to hide the tunnel mouth, we have found a good base!" ”
