Although the Navy Headquarters did not say it directly, this task was for Su Yun to complete. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

The coordinates given in the mission content are 27 nautical miles away from the 24873 town guard mansion in a straight line, that is, close to 50 kilometers, which belongs to the ungoverned sea area, and in the past 10 years, at most there are some small fish and shrimp that have sneaked in, and there are very few reports of deep-sea regular troops, but it is still a dangerous sea area, that is, the enemy may be encountered at any time. With such a task, it was naturally impossible for Su Yun to assign his group of novices to go.

Immediately, he uploaded the target point to the ship's installation database, and then hurried to the dock and left the port.

The weather at this time is cloudy to overcast.

The so-called reconnaissance mission is not as easy as it seems, and thanks to the spy satellite system enabled by humans, the highly evolved deep-sea fleet has become ten times more cunning by now. They used to roam the oceans and could smell the stench from dozens of kilometers away, but now they have long since moved to underwater activities, and only surface on rare occasions, such as under the cover of bad weather, so the satellites in the sky do not want to spy on the slightest privacy. For example, when the town guard mansion No. 24873 was attacked, until Su Yun's hometown was bombed, the naval headquarters failed to give any effective warning.

In addition, the theory that the evolution of deep-sea equipment originated from humans has long been popular, and most people in various countries are convinced of this, after all, even the most strange creatures have no reason to naturally evolve aircraft cannons. This theory has led to the delay in putting many advanced weapons into actual combat, such as intercontinental missiles equipped with nuclear warheads, not to mention whether they can effectively damage the main nest of the deep sea under the sea of 10,000 meters, before the theory of deep-sea evolution is completely and forcefully overthrown, no country dares to set this precedent, because no one can afford the consequences.

If the deep-sea fleet really evolves an intercontinental nuclear missile and shoots at the interior of various countries, there is no need to think about it at all, and the balance that mankind has painstakingly managed for decades will definitely come to naught......

On the other hand, the ship's equipment transformed from the deep-sea core, because of its special nature, whether it is ammunition or armor, it is not the same dimension as conventional weapons - have you ever seen a high-level dual-purpose small-caliber naval gun thinner than .50, Su Yun's secondary cannon is that no matter how you measure it with a ruler, the result is only 10 mm caliber, but the power of the ammunition it fires is not comparable even if you bundle 1000 .50 rifle bullets together, so the deep sea cannot understand and learn this technology. There is also the shield field, which appeared more than 50 years ago, but until now I have not seen a deep-sea battleship that can open a shield field. This is the reason why the profession of ship mother, with the continuous development of science and technology, has not only not been replaced, but has become more and more stable.

In other words, humanity is going farther and farther on the road of hanging and hanging the deep sea.

50 kilometers is not close, and even if Su Yun was almost moving at full speed, it took almost an hour to reach the designated sea area.

It is already very far from the land, there is a vast ocean in all directions, the water vapor in the air is slightly thicker, and the water quality under your feet is quite normal, and there is no obvious sign of being polluted by the deep sea.

According to the guidance of the satellite map, Su Yun came to the coordinate point, and then easily completed the first task of "extracting water samples" - filling the water intake bottle he brought with seawater, and then bringing it back to send it to the Navy Headquarters, it was as simple as that.

The current mission progress is 1/5.

In the second mission, Su Yun released all five water fighters to conduct surface observation within a radius of 20 kilometers, which lasted 3 hours, during which he had time to complete other tasks.

The third task needs to be carried out on the bottom of the sea, which is to extract underwater silt and rock samples, which should be done by a submarine, but Su Yun, as an all-round superman, does not feel too much pressure on this. It's just that the sea water around here is quite deep, and when he went deep into the depths of the ocean and fetched enough silt and rocks, even if he didn't consider the problem of oxygen, Ye spent a lot of time.

The fourth task was to drop an underwater listening device, which was in Zao's equipment bay, and when it was unfolded, it looked like a metal Rubik's cube, which was completed by the way when Su Yun completed the third mission.

And then came the last and most dangerous mission.

Unblock the signal and patrol for half an hour.

As we all know, there is also detection equipment in the deep sea, radar and sonar that humans have, they all have it, and even the effect is stronger in many cases. As one of the most advanced ships, the Zao is naturally equipped with extremely advanced radar and anti-detection equipment, so if you hide it carefully, it will not be detected by the deep sea. However, if the signal shielding is actively contacted, which is the most basic countermeasure and reconnaissance method commonly used, then any orders and actions taken by the Zao will be as obvious as a light bulb in the dark for deep-sea ships that may be hiding in the shadows.

The simple point of doing this is to use yourself as bait to attract the creatures of the deep that may be present. Just like fishing, there is usually a catch, and many human fleets even rely on this method to find the deep sea.

But if you catch a big fish that can't be gnawed, then the fun will be great.

Su Yun did so, with the detection of five water fighters and the blessing of advanced radar sonar, his field of vision can be said to be very broad, even if there is really a big fish that is difficult to deal with, he can immediately know the whereabouts of the other party.

He went on patrol.

……

Twenty hours later, Su Yun fired a salvo that sank a deep-sea expulsion that had emerged seven nautical miles away.

Sixth.

These wandering deep-sea expulsions are called small fish and shrimp, and even in human waters, they appear from time to time. Just like humans can always find a few ants running around in the backyard, they are cannon fodder eyeliner in the deep sea, unless the entire ocean current is intercepted and an inland sea is formed, otherwise it is simply not clean, but with instinctive action, they cannot gather into a group, and naturally they cannot form a powerful threat. It's just a pity that although the lone deep-sea expelled corpses can be sold for some money, but in such a far sea, the water depth cannot move more than a thousand meters, and if you really want to salvage ninety percent of them, you will lose money, so you can only let them obediently sink to the bottom of the sea, waiting for the five-year naval large-scale salvage sacrifice.

Therefore, even if he has repeatedly encountered enemies, in Su Yun's opinion, this patrol operation is still normal.

Half an hour passed quickly, the time was just past two o'clock, and there was still a certain distance from the three-hour aerial detection, it stands to reason that Su Yun could already stop the dangerous behavior of unshielding, and quietly wait for the end of the aerial detection, then he could announce the completion of the mission and set off for the return voyage. However, Su Yun didn't do this, in his opinion, since he was going to stay here for more than an hour, it would not hurt even if the shield was lifted.

If there is a large force in the deep sea, it is just a good time to try the true power of the shotgun after changing the cannon.

But he doesn't seem to have been able to do so.

The time quickly passed half past three in the afternoon, and the water fighter in the sky was running out of fuel, and it was necessary to return as soon as possible, and Su Yun's mission was completed. The mission reward is not very rich, it is nothing more than a supply of 200 each of the four resources, plus a 15.2 mm medium-caliber continuous main gun, which can be modified for the light cruiser Isuzu or Yura, although it is not very unusual equipment, but it is still stronger than the original 14 mm single-mounted gun.

At this time, Su Yun had already killed 21 low-level deep-sea destroyers, and he had almost cleared the sea within a radius of 10 nautical miles as a light bulb, and I am afraid that there will be no living deep sea here in a short time.

But just as Su Yun retrieved all the miniature fighters that had fallen on the surface of the water and was about to return home, his radar suddenly found something abnormal.

"A bright signal?"

Su Yun frowned, looked at the direction on the radar, and judged according to the map, the plane coordinates of the signal were 5.1 nautical miles southeast of him, and this distance was almost the limit of the radar range.

Su Yun looked at the sea in that direction, as far as the eye could see, there was no abnormality, only a conspicuous cursor.

That is, underwater.

He turned around and pulled up the speed of the ship, intending to find out.
