The body began to fall uncontrollably, Xue Jun panicked, at this critical moment, his hands were frantically grasping, hoping to catch something that borrowed strength, but in addition to the mud and sand was a stone.

"Bang-"

The body fell uncontrollably, fluttering, and the feeling of weightlessness was so strong, Xue Jun's heart beat violently, and after two or three seconds, he only heard a muffled sound of "bang", and the whole person hit a hard object heavily, and the huge impact force made him dizzy and almost fainted.

This is not over, before Xue Yu stopped, his body suddenly turned, and then it was light again, and he continued to fall, "Bang-", and when he fell to a wetland again a moment later, he stopped completely.

"Shhhh

Falling twice in a row, Xue Yu grinned in pain, his body was arched into shrimp, he stroked his lower back, he was worried and depressed, he came out to pick up a few fish, and he ran into this thing, it was really bad for eight lifetimes!

"But, fortunately, I didn't get smashed into a pulp, and people are still embarrassed, thank goodness!"

After resting for a while, he eased up a little, sat up with his hands propped up, Xue Yu looked at this strange environment, this is a dark place, the surrounding black rumbling, can't see it really, but a glimmer of light shines from the top of his head, barely bringing a glimmer of light, so that he can't reach out and lose his fingers!

Gradually, Xue Jun's eyes finally adjusted to the light here, and the surrounding scene gradually became clearer, and when he saw this big hole, he couldn't help but gasp.

It was a huge, deep underground cavern, and at first glance, it seemed that there was no end in sight, because it was pitch black at the depths, and the soft mud beneath the feet was unusually damp, and the cave was filled with a strong smell of rust, diesel, and rotten musty.

And beside Xue Xu, there is a wall more than ten meters high, stretching across the entire cave, extending from one end of the cave to the other in the darkness, I don't know how high the top, there is a small hole, and the slightest ray of light shoots down from it.

"There was light coming down from that little hole at the top, and it looks like I should have fallen from there, and then fell to this high wall, and then rolled down the high wall, and there was a second fall......"

Xue Yu kicked the high platform with his foot, making a dull metal crashing sound: "Damn, this thing is so hard, no wonder it hurts to fall, but this sound is ...... It's weird, not like the sound of soil, cave walls, or rocks, but like metal! ”

Xue Jun was curious, and couldn't help but circle around the high wall, this underground cave was unusually vast, and very high, turning the whole cave around, Xue Shu found an amazing thing.

The high wall in front of you, where is the ordinary wall, its shape is a huge cylindrical metal object about ten meters high and more than fifty meters long.

"What does this thing look like...... How is it so similar to a submarine? ”

But isn't it, one end is round, the other end is like the tail of a missile, the blades of the stabilizing wing, propeller, and fan, the more you look at it, the more it looks like a submarine, Xue Shu has seen a photo of a submarine, and this thing in front of him does look like a submarine!

Although it also looks like a missile, how can there be a missile that is about ten meters high and fifty or sixty meters long?

"Rust, diesel,—this thing might be a submarine!" Xue Yu was taken aback, and hurriedly took a few steps back, before absorbing the watermelon knife with his right hand, the feeling that was more uncomfortable than death, he never wanted to experience it again.

In case such a large submarine is absorbed like a watermelon knife, then ...... Xue Jun shivered all over his body, and didn't dare to think about it anymore.

"No! Gotta get out of here, stay in here, no food, no drink, you're going to die! ”

Xue Yan began to get anxious in his heart, and began to search carefully to see if he could find another exit, but after careful inspection, the exit was not found, but he found traces left by humans.

In a corner, Xue found a rusty shovel, a few clothes that were almost rotting, and some messy things, newspapers, cans, and so on.

"It seems that this submarine should have been buried here, but I don't know which country's submarine it is? Also, why should they bury a submarine here? What's the secret......

Submarines, which have been widely used since the First World War, shined in the hands of Germany in the Second World War, so they are widely used for military purposes, and are recognized as strategic weapons, and their development and manufacturing require a high degree of comprehensive industrial capacity, and at present, only a few countries can design and produce them themselves.

The cost of a submarine is not difficult to imagine is very expensive, so why would anyone bury a submarine here?

Xue Shu felt extremely puzzled, but he was not in the mood to doubt these things now, because Xue Shu had discovered something that made him very desperate, and that was the shape of the hole.

It is said that it is a cave, but it is better to say that it is a tall underground tunnel - an underground tunnel specially used to bury this submarine, this tunnel is at least twenty or thirty meters high, even if Xue Yu can climb the submarine ten meters high, it is also ten meters away from the entrance of the cave at the top!

At a height of more than ten meters, there is nowhere to borrow, how to get out?

"Am I really going to die here?" Xue Jun's face was ugly, his heart sank to the bottom, the sky outside gradually darkened, and the light transmitted from the top hole became darker and darker.

"Whoa-la-"

At this time, a splash sounded, Xue Jun looked up, and vaguely saw a stream of water flowing down from the small hole at the top, the water flow was not very large, only a small one, intermittent, but then, a large stream of water fell from the hole, and it became bigger and bigger.

Staring at the falling seawater, Xue Jun's mind flashed, and his eyes gradually lit up.

"Sea water? Maybe...... Hope to get out! ”

Xue Yu couldn't help but be happy, he thought of the possibility of going out, as long as the sea water continued to flow down, and then filled this cave, wouldn't he be able to get out?

According to his estimates, the hole at the top, which is located on the shore, will allow the sea to overflow the hole if there is a big wave, and then the water will flow into the cave.

"Now I hope for the tide to rise, and if the tide rises, the hope of going out will increase greatly!"

His eyes were firmly fixed on the entrance of the cave, Xue Jun clenched his fists, and looked eagerly anticipating, this cave was too long and too big, and it was impossible to fill it with a little waves.

Only high tide can bring a large amount of seawater, and generally speaking, once the tide rises, it will last for 6 hours before the tide will fall!

6 hours, that's enough to fill this cave!

"Rising tide! The tide must be high! ”

"Boom—"

Maybe God heard Xue Shu's prayer, about five minutes later, there was a wave like a galloping horse outside, the rolling waves carried the power of heaven and earth, the sound was as loud as thunder, shaking the heavens and the earth, Xue Yu stood at the bottom of the cave, and he could feel the roar of thunder coming from the top of his head.

Immediately after the sound of the waves, a large amount of seawater poured down from the entrance of the cave, smashing down on the submarine, smashing out a "bang" muffled sound, how much kinetic energy should the sea water falling from a height of twenty or thirty meters carry?

Xue Jun didn't dare to stay longer, and hurriedly ran towards the tail of the submarine, the hole was almost above the head of the submarine, the impact of the head was the largest, and the tail was the least impacted.

"Boom—"

A thick stream of sea water poured down from the top, and as time went on, the hole at the top was also pounded bigger and bigger, at first it was one or two meters in size, and after only two minutes, it became a large hole five or six meters in diameter.

The large hole of five or six meters has a large amount of sea water pouring down every second, and the water level of the cave force is gradually rising!

"Damn! The water level is all over the chest, hold on, as long as you hold on, you can get out! ”

"Get out alive!"

Xue Yu clenched his teeth, his ten fingers clasped tightly on the cave wall, resisting the impact of the sea, however, as the water level became higher and higher, he received more and more buoyancy, and his feet would leave the ground at any time and float.

"At this time, it would be nice if he could hold something...... Xue Yu said secretly, thinking of this, his eyes couldn't help but look at the tail of the submarine, where the horizontal and vertical stabilizing wings arranged in a cross shape were installed at the tail of the submarine.

A horizontal stabilizer wing is arranged on the port side and the port side, a vertical stabilizer wing is arranged on the upper and lower wings, a rudder plate is placed on each stabilizer wing, and a propeller is installed at the rear end of the tail section.

"If you can hold the fan blades of the propeller, you can not only stabilize yourself, but also hide there from the impact of the current...... But what if it's like before? ”

Xue Yu was thinking wildly, and before he knew it, the sea water had already hidden his chest and began to drown on his neck.

"Ah——!h

The water level rose and the buoyancy became bigger and bigger, Xue Jun didn't pay attention for a while, his body was suspended, directly washed away by the current, and then slammed into the cave wall.

"Ahem, ahem!"

After drinking several mouthfuls of seawater in his mouth, Xue Jun's face turned red, fortunately, his swimming skills were good, he reacted quickly, and hurriedly moved, and the whole person immediately surfaced, but in the face of the impact of seawater, no matter how good his swimming skills were, he was also washed away.

"Ahh

The back hit the submarine hard, Xue Yu's eyes were dark, and he almost lost his breath, this was just the beginning, the hole was getting bigger and bigger, the sea water poured down per unit time was getting bigger and bigger, the impact was getting bigger and bigger, the water level was getting deeper and deeper, and the movement was getting bigger and bigger.

Xue Fei is like a goldfish in a fish tank, the owner began to add water to the fish tank, Xue Fei drifted with the current, up and down, stumbling, even if he stood at this end, more than 50 meters away from the hole, the impact force was still not small.

Sometimes it hit the wall of the cave, sometimes it hit the submarine, and after a few times, I was almost dizzy, my eyes were full of stars, my head was bleeding, and my internal organs were as painful as if they had been displaced!
