The faint sound of the water was quite turbulent, as if there was an underground river beneath this hole. But Liszt's brow was still tightly furrowed, and he listened slightly, and could still hear that the so-called water was not close to him, and there was a faint echo in it, obviously this pit was connected to a turbulent underground river, and because of the collapse of the cave, Liszt and them appeared in front of them.

The light was still bright, and even though it could not shine into the collapsed crater, Liszt glanced down a few times, and could still perceive the huge environment of the cave underneath, at least four or five times larger than the cave he was in before. And there seemed to be other caves in the cave, and the slight sound of water was also heard in the front of it, and it seemed that the turbulent and subtle sound of the underground river should have been transmitted from the small mouth of the cave to this side.

Slowly licking his lips, a Marine soldier also came over, the M4A1 assault rifle in his hand subconsciously pressed against his shoulder, looking at the dim appearance below, he reached out and took out the tactical flashlight at the back waist, opened it lightly with his thumb, and a pillar of light swept downward. And he looked at the empty appearance, and couldn't help frowning, and said to Liszt next to him: "Captain, the cave below looks very big. ”

"At least seven or eight hundred square meters, it's really interesting."

The twelve Marines all gathered around the edge of the crater, and they also took out their tactical flashlights in their hands, and when they turned on, they formed dazzling pillars of light, illuminating most of the appearance of the cave below. A more experienced Marine also frowned slightly, and the M4A1 assault rifle in his hand was subconsciously aimed at the mouth of the cave that appeared at the bottom of the cave. There was a slight concern in his tone: "It's almost like a labyrinth." ”

Formation of karst caves. It is always accompanied by countless karst caves. This unique geographical location appears to have been formed as a result of weathering or changes in geological structures. But the most likely thing is that after a volcanic eruption, the air left behind in the cavities and the rapidly solidifying magma left the gaps that formed these caves. The smooth rock wall could be felt, and although Liszt did not understand geology, he still had some knowledge to distinguish magmatic rocks.

"It's better to go down and have a look, it seems like there's no other option for us."

Also a Marine, he turned his head to look at the tunnel behind him. The cracked boulders had been completely blocked there, and looking at the countless rubbles piled up inside, I also knew that the original entrance to the cave had also completely collapsed with the cracking of the mountain. He slowly gritted his teeth, and also clenched the M4A1 assault rifle in his hand and said: "If this passage is dug up, it will be too costly for us. ”

Originally, the tunnel entrance of this karst cave was slightly curved, and the small space and entrance could not squeeze a few people at all. If they dig with sappers and shovels, looking at the amount of rocks and soil, I am afraid that they will not be able to dig up effectively in more than ten hours. And they are not sure if there will be a secondary collapse during their excavation, especially for the fragile caves. The possibility of the soil and rocks continuing to collapse is also absolutely high.

And if you borrow bomb-like blasting means. I'm afraid it won't take twenty or thirty minutes to directly blow up the passage again, but now that I think about it, I know that if there is another strange explosion on this small island, the group of Soviet soldiers who have become frightened birds will definitely be abnormal. And this place is so close to the continent controlled by Canada, once a large number of enemies are reinforced, even their special forces will not be able to resist!

They are all trapped in this cave, and if they don't make a decision, I am afraid that when the reinforcements of the Soviets arrive on the island, a tighter defensive ring will be set up, and it will be even more difficult to evacuate. The Soviets, despite their reputation for rigorousness, have shown that most of them are still careful in their mathematical talents. Once the cave leaked, Liszt would be left with only the sheer number of Soviets and their own miserable death.

"Work in groups of three, move fast."

At the price of 1 point each, Liszt already had three more coarse hemp ropes in his hand. He tugged hard at the rope loop, which was nearly five meters long, and the strong force made him nod secretly, the items exchanged in the game system were definitely high-quality, which he was very relieved of. At the same time, Liszt handed the three circles of thick hemp rope in his hand to the marines next to him, and at the same time held his Winchester to look at the cave below, and said with a deep sigh: "I'll go down first." ”

He didn't use the hemp rope at all, he just turned over and jumped down the hole neatly, and the height of nearly four or five meters was nothing to him. Just a roll easily, Liszt instantly stood up on the slippery ground, the Winchester shotgun in his hand was aimed at the surrounding darkness, the faint blue light flashed like a star, and after a while, he said slowly: "No abnormality found!" ”

Three thick hemp ropes were immediately thrown down from above, and at the same time, a member of the Marine Corps had also quickly slid down the hemp rope, and the excellent combat boots on his feet were still effective in this slippery environment. They all looked around with the weapons in their hands, and the light of the tactical flashlight shook with their movements, illuminating the huge underground cavern through the air, even if there were enemies hiding here, there was probably nothing to hide.

But before Liszt's order was given, they dispersed quite tacitly, and a Marine with an M4A1 assault rifle and a Winchester M1887 shotgun in his hand was carefully moving in this huge area of seven or eight hundred square meters, and the light of the tactical flashlight had already illuminated every area of the cave.

"Captain, I think you should come and see this!"

Liszt's eyes were still staring at the strange cave, but the voice of a Marine Corps member instantly sounded behind him. He frowned slightly, not to hear fear or panic in that voice, only the slightest hint of confusion. And Liszt immediately turned around and walked over, watching the soldier holding a tactical flashlight, shining the dazzling pillar of light into a cave, and at the same time there was a certain disbelief in his voice: "I see, I see, see a beer can floating?" ”

The entrance of this cave is about two meters over, and the faint sound of water is spreading uncontrollably underneath. But Liszt's gaze froze instantly, he looked at the light from the tactical flashlight, a silver bright thing was half-sinking and half-floating on the water, and the water surface was less than a meter away from him, Liszt could clearly see that it was a can of fresh beer from New York, which made him frown tightly: "Beer cans? Wait a minute? It seems..."

"It's really a beer can!"

Liszt turned his head to look at the soldiers who had not noticed anything unusual and were gradually gathering, and he couldn't help but smile on his face. He seemed thoughtful, but he took a half step back, turned to the soldiers, and asked, "I suppose we should all swim or dive?" ”

However, this group of marines showed a certain confusion on their faces. But they all nodded, for a group of soldiers belonging to the navy, swimming or snorkeling was a subject of training. Especially for the island seizure operation or the river operation, it is much stronger for the ordinary army. And even if it is a river or lake battle, compared to the inland professional river troops, it is not much to give in at all!

"Maybe we can really get out of this island easily, and we can use this island as a warehouse for supplies!"

With a slight smile on the corner of his mouth, Liszt looked up at the two standing lamps that were still connected to the storage box and emitted light, releasing light in the cave on the top floor. He didn't go to close the idea of closing it, but nodded with satisfaction, and the data stream in his hand spread rapidly with the certainty in his mind, and formed a rapid entanglement of data links, materializing the items in the system into this world.

Fourteen sets of underwater combat suits, as well as fourteen oxygen tubes and respirators, were neatly placed on the ground next to them. But the spreading data in Liszt's hands did not stop at all, but instead became entangled into the data chain and manifested the small and flat tools in a very fast way, and also appeared in the open space of this cave.

"Underwater... Thruster? ”

There were still Marines who immediately recognized the flat, small thing, and as elite Marines in the Navy, they had also heard of this famous tool for special operations. And a soldier also reached out to pick up the surfboard that was as thick and heavy as a trumpet, but it actually belonged to the underwater thruster of the special operation, and couldn't help but look at Liszt with wide eyes and said: "Captain, you mean, we are underwater propelled to leave the island?" ”

"No, not leaving the island."

But the smile on Liszt's lips continued, and he took a deep breath, and his excellent sense of direction allowed him to find the direction of the east in this cave. Gently clenching his fist, he also picked up an underwater thruster, looked at the small and flexible structure, smiled and nodded at the surrounding marines: "Instead, use the underwater thruster to enter the rivers of Canada and launch special operations!" ”

PS: I'm sorry guys, but I've been a bit busy lately. After all, my daughter-in-law's belly is also big, and I sometimes have to stir-fry and go out or something here, and the update will be a little delayed.

Anyway, it's the completion of the two shifts.,I hope you can vote for more monthly tickets.,I'll strive for more updates! (To be continued.) )
