Cold, shaky......

Su Yun was woken up by the sound of the ship's alarm, but as soon as he opened his eyes, he was startled. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

About 20 minutes have passed since he fell unconscious, and the energy of the ship's equipment has been reduced from 45 points to 21 points, which is a severe break, which will already affect the normal performance of the ship's strength.

This is already a very serious situation, it seems that just now it was sucked to the end by the whirlpool and pulled to an unknown place, and the loss of the ship's equipment in the process is much greater than the combined thunder explosion just now.

It wasn't for the protection of the ship's equipment, and now Su Yun has already been crushed to pieces, and there is no corpse to die!

Su Yun shook his head, which was still painful, and sat up.

At this time, the ship's searchlights, radar, sonar, and ship's engines are all turned off because of the state of emergency, and the main and auxiliary gun crews, machine guns, and torpedo tubes are also locked - when the ship's equipment is operating normally, the shield force field is not a completely closed state, and there must always be interaction between the internal and external environment, but after the emergency is transferred, these interactive functions will all be turned off, and the defense mode will be turned on, so as to ensure the personal safety of the ship's users to the greatest extent.

Therefore, it was dark all around, and Su Yun couldn't see anything clearly, just like a blind man.

But he only moved slightly, and with a sense of his surroundings, he found that he was no longer in the water.

The sound of running water was all around, and it was bitterly cold.

Su Yun propped up his body, obviously feeling that the physical strength brought by the ship's armor had decreased slightly, and then, he did not immediately turn off the emergency system, nor did he rush to turn on the searchlight, but activated the night vision mode.

A green light lit up all around.

……

This place, it seems, is much bigger than expected.

It was a huge hollow with no end in sight, the top of the stone above it was about 50 meters high, and where Su Yun was located was a corner of the hollow, and he was standing on a stone mound that had not been flooded. The surrounding ground seemed to be in the midst of a catastrophic flood, countless rubble, deep-sea plants, animal corpses and inconspicuous pollutants slowly drifted into the distance, Su Yun looked at the upstream of the flood, a distance of a few hundred meters, he saw a huge gap in the heights, from the gap, more sea water carrying the power of ten thousand jun, is surging in.

Su Yun probably understood what was going on.

The falling boulders smashed through the bottom of the trench, which was not thick, and opened up the sea water with this underground space, so that the great whirlpool was created. At first, he thought that some monster was sucking whales at the bottom of the sea, which led to that terrifying scene, but now it seems that his idea is really too sci-fi, after all, except for nature itself, even the largest deep-sea monster cannot make such a terrifying sound.

Looking at the locator, the current Su Yun was indeed at an altitude of about minus 1,800 meters, which confirmed his conjecture to some extent.

But......

Although it is really unusual and amazing to have such a large cavity in such a deep underground, Su Yun always feels as if he has gone farther and farther! Obviously, he just ran out for a reconnaissance mission, and now he has returned to the town guard mansion to exercise, take a bath, deal with official business, and sleep, how did it evolve into this strange painting style now?

Alas, this has come to this, so let's concentrate on finding a way out.

Su Yun observed the gap for a moment, and found that the water flow had neither a weakening trend nor a tendency to continue to strengthen, as if maintaining a balance, and looking around, the sea water was all flowing into the distance, and the water level was as low as a stream, and if you want to fill this place, you don't know what year or month it will take. It seems that the plan to return the same way is not to be considered.

It seems that there is no other way to go but to follow the direction of the current and look for an exit.

The detection showed that although the air here was not very fresh, it was at least suitable for breathing, and this good news made Su Yun breathe a sigh of relief, and he quickly turned off the gas sealing system to let the air outside in. Then, he jumped into the water and stood still, without even turning on the engine, and the surging water around him sent him quickly downstream.

Ten minutes later, the coordinate meter showed that Su Yun had drifted out for 1 kilometer, but unfortunately, the positioning system had already failed, and on the ocean map, his position still maintained the coordinates when he was deep in the sea, and there had been no change for a long time. The wireless receiving device is also a blank space, and in this kind of closed underground, even if there is no deliberate electromagnetic shielding, it is very normal that there is no signal.

The space around it was getting bigger and bigger, and if it weren't for the stalactites that could be found everywhere to prove that this was at least a natural cave that was thousands of years old, Su Yun would probably think that someone had deliberately hollowed out this place.

After another five minutes, Su Yun smelled something unusual.

Well, he hadn't seen anything, heard nothing, felt nothing, and there was still a cave in front of him, which was wide and narrow, but now his instincts, which he had long been convinced, told him that perhaps something was waiting for him around the next corner.

This feeling made Su Yun vigilant, and he left the center of the most turbulent current, approached the "shore", and slowly slowed down until he completely stopped and returned to the shore.

He unlocked the weapon.

Then, softly and slowly, he continued on his way, ready to react to sudden situations and advance and retreat with ease.

150 meters away, the current ushered in a big turn, countless waves crashing on the stone walls made the place chaotic, and many deep-sea debris that came with the current was hung in the gully around the corner. At the edge of the passage, there are obvious traces of being breached, and it is obvious that this place should have been a dead end, but when the sea rushes here, the huge water pressure has forced a new path.

Su Yun cautiously passed through here, then looked along the "new path", and finally saw the source of his intuitive uneasiness.

It was a huge cavern that had never been heard of before, as if it had formed a sky deep underground, and on the open terrain that stretched for at least a few square kilometers as far as the eye could see, there were massive, pitch-black, strange-shaped buildings. With just one glance, Su Yun knew that these "buildings" were by no means naturally formed, nor could they have been built by humans.

Because, he smelled a strong smell of familiarity.

Su Yun recalled that this aura was the same as when he broke through the body of the deep-sea monster and directly faced the jet-black slurry in it.

That is to say-

Su Yun experienced twists and turns, experienced a change in thinking, and finally got the same answer as the absurd idea he had at the beginning.

It's a deep nest.

That's right, the deep sea also has a main nest, and after an in-depth understanding of the previous practice, Su Yun felt that they were somewhat similar to a certain game race Zerg in his memory, but they were not exactly the same. This strange creature is born in an egg as a juvenile, and after its growth is completed, it becomes a deep-sea banishment, and then produces branches and evolves into a variety of different high-level ship species, and this growth process is not long - an ordinary deep-sea larvae, under the right conditions, from birth to a battleship-level behemoth, it only takes a few years, almost like planting a tree.

Generally speaking, most of the deep-sea larvae that were pulled by the transport ship to lay eggs everywhere were destined to become members of the deep-sea miscellaneous soldiers, and those real deep-sea main forces, such as those WU-class and RU-class who attacked the town guard last time, were born and grew up on the island that Su Yun swept that day, but the special deep-sea main nest that went deep into the ocean underground.

It's the place in front of you......

Su Yun took a deep breath.

But just as he was about to lament that my life was at stake, he suddenly discovered something.

This main nest of the deep sea, from a distance, is cold, dark, and terrifying, but there is only one thing, it is too quiet. The inner wall of the main nest was washed away by the ocean current, and although it was large, it could not withstand the constant influx of seawater, but after so much time, no deep-sea monsters reacted, and the entire "city" composed of the complex seemed to be dead, dull and lifeless.

In other words, this is most likely an abandoned main nest?

After all, even the deep sea can't ignore the conservation of energy, how big the warships they evolve are, how much energy they have to consume, no one knows how many deep sea main nests there are on the earth today, but just those that have been discovered, there are already countless counts. These main nests, after operating for a period of time, will deplete the surrounding energy, and they will no longer be able to evolve new deep-sea warships, and it is natural that they will be abandoned.

Su Yun looked at Zhou and found that even the rocks showed an unhealthy color, and when he connected to the fish bones that had been piled up for an unknown amount of time in the trench outside, and the thriving animal and plant life scene outside, he could probably judge that this place had not only been abandoned, but also abandoned for quite some years.

Just like the original No. 24873 Town Guard Mansion, when Morita Kiyoshi first came, it was also overgrown with weeds......

This discovery made Su Yun realize that this may not be his place of death.

Want to check it out?

Su Yun suddenly had a strong curiosity, you must know that the above understanding of the deep-sea main nest completely stayed in the internal information provided by the navy's official, he didn't expect to see it with his own eyes so soon.

Therefore, even if it is just a waste product, it is also very attractive to Su Yun.

What's more, my intuition did not send follow-up danger signals.

Su Yun quickly made a decision,

He jumped into the water and followed the endless flow of water into this vast and moist underground space.
