Wang Yu finally determined that there were sirens in this world, and at the same time, this world also formed organizations such as the "World Admiralty" to deal with the threat of sirens through cooperation.

Of course, this is the only thing he can be sure of after all the twists and turns.

As for the rest of the content, Wang Yu said that he didn't understand it.

What is the commander of the port area, the commander of all the armed forces in the military port?

That person belongs to a family that has more cards than himself, a commander who can only command one warship, no wonder he can form a combined fleet.

And those "white eagles", "heavy cherry" and other titles, what the hell are they?

Wang Yu could deduce that this was supposed to refer to different parts of the world, but the names of those regions were very different from the ones he was familiar with—he wasn't too surprised considering that he was already in a different world.

It's just that from the current point of view, there is a huge gap between this world and the previous one - the only thing that has not changed is probably the various underlying elements that build this world, such as gravity or that gravity, such as air or the air that can breathe, such as seawater or the seawater that can make battleships float......

However, knowing this is indeed not helpful to Wang Yu's current situation.

It seems that his path to establishing a worldview will indeed not be easy.

Wang Yu adjusted the channel of the wireless point, hoping to get more information.

And after an hour of listening, he got his wish.

At present, he knows that the strength of the sirens in this world is not high, for example, there are routine ships coming and going in various regions across the sea, and there are so-called safe sea areas on the sea to provide shipping routes.

In this world, human beings, presumably mainly referring to the "commanders of the port area", can organize a fleet of a certain size, take the initiative to clear out some sirens who have invaded the safe seas, and generally return victorious.

This is unimaginable in the world before him, except for the sea near the continent that can be a little safer, there are traces of siren activity in the ocean area, as long as the ship dares to go to sea, the siren dare to rush up and attack.

And taking the initiative to eliminate the sirens is even more fantastic.

In the previous world, the strategy used by the human fleet was to passively resist the Siren's attack, and rarely would take the initiative to find trouble with the Siren - when sailing, the Siren could dodge when encountered, and the fight would only start if they couldn't dodge.

Unless the Sirens need to be driven away from the offshore area during a large-scale Siren invasion to prevent them from shelling land, the human fleet will actively seek to engage the Sirens.

Thinking back to the common-sense content of the previous world's battle with the sirens, Wang Yu quickly retracted his divergent thinking.

It seems that I have come to a world that is a little peaceful, but not so peaceful.

This may be good news, because it means that Wang Yu and the Annapolis, which was built specifically to fight the sirens, still have room to play and then find a way to integrate into this world.

As for how to fit in, that's something that needs to be considered later when we get more information.

If it goes well, then Wang Yu can pat his chest confidently like "Ma Fuzi" and say, I have been in this world for many years, in fact, I have long been a person in this world.

Nothing too much of a problem.

Time passed little by little as he thought.

The moon, which had made the night sky somewhat bright on both sides, slowly disappear from the sky, replaced by the morning light gradually brightening on the horizon.

What Wang Yu listened to next didn't have much use, probably some talk show radio or songs on demand, but to Wang Yu's surprise, when the music started to play on the radio, he heard the moonlight sonata......

Are there Beethovens in two completely different worlds?

Wang Yu said that he was powerless to complain, it seems that art is not only borderless, but also worldless.

However, considering that the two worlds already have the same language, this strange overlap is not a matter of much concern.

The morning light was faint, and Wang Yu looked through the porthole at the rising sun in the east.

"Well, it seems that the sun in this world is still rising in the east and setting in the west, which is a good phenomenon."

Wang Yu said a useless nonsense to himself.

The southeast, northwest, and northwest are his judgments based on the information of the magnetic compass that can still work, and considering that the magnetic declination of the new world is unknown, the results are not estimated to be very standard, but there is always an approximation.

This at least proves that the planet also has north and south magnetic poles.

He found a watch, assumed that the sun rose at six o'clock in the morning, and adjusted it to the corresponding position—he planned to compare it with his previous electronic watch to see if the speed of world time on both sides was the same.

Then he sat down in his seat and waited quietly for the sun to rise.

The sunrise on the sea is always very spectacular, mainly because nothing can block the spread of sunlight, and the red sun appears on the sea, reflecting the sea in the east - of course, the scenery is not important, the important thing is that Wang Yu determined that this world is still a sun through the sunrise......

It seems that the two moons are characteristic of this world, and the sun is still normal.

At least the planet is still orbiting a star.

If there were three rounds of suns in the sky at this time, then Wang Yu estimated that there would be no other way than to dehydrate on the spot.

Far from it.

After the sun rose, Wang Yu walked quickly to the open platform at the top of the bridge, that is, on the fifth floor, and his eyes first stayed on the dazzling blackened artillery traces on the battleship for a moment, and then borrowed a telescope to start observing the sea around the battleship.

He had only seen the situation by moonlight last night, and now he could see more clearly, the battleship was sailing at a slow speed of less than ten knots on the edge of an archipelago of sea—about six or seven nautical miles away on the starboard side of the battleship, a large number of islands could be seen dotted on the sea.

The distance between the islands is only a few hundred meters, and the long one is several kilometers, and the entire archipelago is endless, and even with the help of a telescope, Wang Yu cannot see where the edge of this archipelago area is.

He couldn't help but smack his lips.

This is perhaps the more peculiar part of this world.

After all, in the last world, even the famous Micronesian islands did not have such a high density of islands.

At the same time, he was also a little glad, fortunately he slowed down the speed of the ship last night and determined the course, so the battleship is now sailing from the edge of the archipelago water, if it does rush in, the dense reefs and narrow waters inside are estimated to make the battleship extremely uncomfortable.

Wang Yu had no intention of going to the middle of the archipelago for a walkaround, so he kept the battleship on a fixed course and continued to move forward.

Due to the demands of the Sirens, the Annapolis has an unrivalled endurance, being able to sail 11,000 nautical miles at fifteen knots when fully fueled.

Although the battleship had used up a lot of fuel reserves in many previous naval battles, the remaining amount was still enough for the warship to maintain the current speed of about 10 knots and sail about 4,000 kilometers.

4,000 kilometers is not a small number, about 2,200 nautical miles.

Wang Yu felt that if he kept a course constant, then he would always be able to meet land - or at least some human ships - before he ran out of fuel, and from the information gathered, it seemed that the "port commanders" of this world would go to the ocean to exterminate the sirens, so he would be able to bring himself to the civilized world when he met them.

Although this idea is a bit risky, it is much better than stopping the ship in place.

In any case, the world is not calm, and the threat of the sirens still exists.

In the face of the sirens, the moving battleship has the ability to fight back.

The only result for a stationary ship is to be devastated by the extremely accurate Siren Core Blast.

The battleship picked up a slight speed and turned its back to the rising sun as it continued along the edge of the archipelago waters.

The propeller stirred the seawater, creating a straight white trail on the surface of the sea behind the battleship.

The stable navigation of the battleship can be entrusted to the battleship's automation system, Wang Yu does not need to stay on the bridge all the time, he uses the time of smooth navigation to recover the record tablet that he threw in the lifeboat before.

He re-read the previous battle log as he muttered.

"Who knew a simple escort mission would turn out like this......"

Following the battle record, his mind drifted back to before he traveled into this world.

Wang Yuzai and the Annapolis were originally on a receiving mission, receiving a transport fleet.

The transport fleet was responsible for transporting a shipment of supplies, some ship design materials, and a special "siren containment".

As a result, the transport fleet was attacked by a large number of sirens in the ocean-going region.

The main battleship, which was supposed to be responsible for escort duty, suffered heavy casualties after several battles and was unable to continue escorting, so it sent a distress signal to the naval base on the west coast of the Pacific Ocean through a radio signal that was unobstructed at a certain moment.

Therefore, the Admiralty urgently formed a temporary task force and immediately set out to meet the transport fleet.

But no matter how fast the ship was, it was like that, so by the time the high-speed formation arrived, it was already too late.

The transport fleet was fiercely attacked by the Sirens, most of the capital ships were sunk, and only a few destroyers were still using their maneuverability to constantly attract the attention of the remaining Sirens.

And the transport ship that was the target of the escort was also badly damaged and could not continue sailing.

The addition of a new force crushed the remaining sirens and freed the ruined fleet - but since the ship was so badly damaged, the commander of the transport fleet decided to temporarily transfer the main "cargo" of the transport, i.e., the ship's design data and "siren containment", to the Annapolis, which had the least number of crew and the most space.

The rest of the transport ship could not be recovered without cranes or engineering ships, so although it was a pity, the fleet had to be allowed to sink into the sea on the premise that the fleet had to set off immediately.

Ship design data is stored in several high-capacity storage devices, and the "Siren Containment" is a 0.75-meter-long iscosahedron that doesn't add up to a lot of space.

At that time, the fleet was relatively safe, and there was time to stop the ship to complete the transfer of these small cargo and the rescue of the survivors.

And the rest of the matter is already known, the returning fleet encountered wave after wave of siren attacks on the way, and then the battleships sank one after another, and in the end only the Annapolis commanded by Wang Yu remained.

Looking at the combat record, Wang Yu's thoughts returned from memories to the present.

"It couldn't be that 'containment' that attracted the sirens' to attack."

Wang Yu muttered to himself.

He stood up and walked out of the bridge.

In any case, it is necessary to check the "cargo" on those battleships.

Those things were now housed in the lower deck compartments protected by the battleship's armor boxes.

Finding the corresponding cabin, Wang Yu pushed open the heavy cabin door, and saw the iscohedron placed in the middle of the cabin, glowing with metallic luster and dark blue in color—a complex object with twelve top corners, twenty faces, and thirty edges.

It looks like a metal ingot.

But Wang Yu, who had participated in the transportation before, knew that this was definitely not an ordinary metal creation - the volume of this icosahedron was about 0.92 cubic meters, and this volume of metal close to one cubic meter, even the lowest density of lithium metal, was a full 500 kilograms, close to the mass of a 305 mm bomb.

And now this thing in front of me......

At that time, it should have been easy to carry it with only three people.

Wang Yu conservatively estimated that he could move it with force.

He circled around the icosahedron twice, but the thing sat firmly on the ground, and nothing changed.

"These sirens are so consistently incomprehensible......"

Wang Yu shook his head, in the world before him, the World Coalition Government had an organization responsible for containing these strange sirens, and they always had various functions—such as the "Kraken" system on the Annapolis......

He's not a professional, so he's not going to do what a professional does.

Touching the unknown details of the "siren containment" seemed to Wang Yu to be a bit similar to the act of welding a detonator sawing a light bulb, so he didn't plan to study it in detail - it was enough to make sure that nothing had changed at the moment.

Since there are sirens in this world, then perhaps the research institutes in this world also carry out research on siren creations, and if there is an opportunity in the future, let them professionals help study this hot potato, which is a safer way.

Wang Yu took one last look at the motionless icosahedron, and then left the cabin.

He returned to the bridge and continued to stand by the radio.

This is the only way he can get information at the moment, so he continues to try to summarize the contents.
