That afternoon, Xu Xingchen, as usual, brought the new Jinan and four 037 little guys to briefly get familiar with the environment of the Admiral's Mansion, and then completed the upgrade and transformation for them.

The next morning, Xu Xingchen took the main fleet to attack again, and the targeted sea nest numbered 1-4, 1,000 kilometers north of the coastal base around the island.

With the assistance of land-based fighters, the battle process was also unsurprising and ended more than an hour after the start.

But unfortunately, no soul core was found, and no new ship girl even appeared.

With the experience of Black Fish, Xu Xingchen led his fleet to the Hai Nest battlefield and searched carefully, but found nothing.

When Xu Xingchen left helplessly with the fleet, several ship ladies quietly monitoring the water's underwater suddenly felt that their sonar had reacted.

Among them, Danyang responded the fastest, and report it immediately through the Fleet Channel:

"Admiral, there is movement under the water. Something is coming up. I am putting on the pendant sonar!"

"Why did you come so late this time?"

Xu Xingchen subconsciously muttered, and immediately asked Danyang to inform the entire fleet of the news.

When other ship girls received the message, they immediately dispersed completely, widened the distance from the target point, and used the passive sonar inside the ship to receive the signal.

There are several ship girls, like Danyang, who control the air-visiting helicopter remotely and release the sonar, wanting to carefully check the movements underwater.

It doesn't matter if this investigation is made, these ship girls were shocked.

Danyang reacted the fastest way. After she realized what it was, she immediately subconsciously used the direct broadcast channel to warn the entire fleet:

"Maybe it is a submarine! The submarine that is deployed in a ship-mounted manner! It is not an ordinary newborn ship girl! Attention admiral! Everyone should pay attention!"

Among all the ship girls in Xu Xingchen's fleet, Danyang is basically the fastest in response to various unexpected situations. After the strengthening of various modern equipment, it is even more powerful.

When Xu Xingchen heard the warning sounding next to him, he subconsciously issued an order, preparing to let everyone throw deep rocket bombs.

As a result, at this moment, the little Chongqing, which was slightly filled, directly broadcast more important news:

"The voiceprint characteristics are your own people! Don't throw deep bullets! The other party's ship is deployed, and I can identify it. It is a submarine of our same line!"

This message from Xiao Chongqing’s report triggered a burst of exclamations in the channel:

"Owner?"

"submarine?"

"Is our ship girl?"

Immediately afterwards, this time, I also reported my experience:

"It is certain that there are at least five targets that are gathering together, and the voiceprint characteristics are indeed very familiar.

"And this kind of floating amplitude is obviously not a submarine ready to attack, but it will be discovered otherwise it will be too easy to be discovered.

"This is a situation where you take the initiative to float after you are discovered, so you don't have to worry. Be alert, just pull away and copy it a little, just wait and see."

Listening to the two of them, Xu Xingchen immediately breathed a sigh of relief, his mood immediately became expectant, and directed everyone to disperse their warnings.

So Xu Xingchen and more than 20 ship girls looked at the sea water together, looking forward to the possible new companions.

Not long after, accompanied by a swell of water, several figures of black bodies jumped out of the water.

Xu Xingchen took a closer look and found that there were eight little girls this time. They were not tall and were all wearing diving suits or swimsuits of different shapes.

They are indeed different from the newborn ship girls before. They came directly with ships, and the shape of the ship kit is different from other ship girls.

The ships of other ship girls are piled with various ship-based equipment, which is quite complicated overall.

Their ships are very simple, so simple that they have almost nothing. Some are like floats, some are like torpedoes, and some are like dolphins.

They are indeed submarine ship girls, and looking at the Bayi Navy flags on their ships, they are indeed natural teammates of the same genealogy.

After confirming his identity, Xiao Chongqing ran to the front, with Anshan and Changchun following:

"I'm Chongqing!"

"I am Changchun."

"Who are you?"

Looking at the ship girls who were rushing up enthusiastically, one of the eight submarine girls had a chubby face and responded with an extra serious response:

"Type 033 conventional submarine, hull number 256, I'm very happy to meet everyone."

The other seven submarines also reported their identities next to each other. They were all of them of Type 033 submarines, and they all had hull numbers and no special names.

The Type 033 submarine, also known as the Type 633, has a water displacement of 1,475 tons, a submarine displacement of 1,830 tons, a submarine depth of 300 meters, and its main weapon is eight 533 mm torpedo tubes.

The technical prototype of the Type 633 submarine can be traced back to the XXI U-shaped submarine designed and produced by Germany during World War II.

After Germany's defeat, the Soviet Union seized a batch of military technical data from Germany, including technical data related to U-boats led by XXI-class submarines.

The Soviet Union applied the submarine technology obtained from Germany to its new designs to form Z-class submarines and W-class submarines.

Subsequently, the Tianqingshi Design Bureau improved the first two-class submarines and designed the Type 633 submarine, code-named R-class in the West.

In the early 1950s, the Republic obtained technical information on the Type 633 submarine from the Soviet Union and began to be built in China in 1962.

By the time production was stopped in 1984, a total of 84 Type 33 submarines had been built in China.

Most Type 033 submarines are like their distant sisters, without their own special ship name, and only one hull number as their only code number.

After the 1980s, the Type 033 submarine that was still in service used the name of expedition + number according to the naming rules of conventional submarines.

But in custom, it is still called a certain boat, such as the 256 boat, which broke through the second island chain for the first time and entered the central Pacific Ocean in March 1980.

Xu Xingchen was a little excited when a new ship girl appeared, and a new ship type appeared.

Immediately let Chongqing ride over and let Changchun ahead pick up eight little guys back.

After the two sides met, Xu Xingchen went over and signed the eight little guys, and then took them back together.

Take a water-Hong5 seaplane and, under the escort of land-based fighter jets, return to the home port base together.

Xu Xingchen has obtained relatively few submarine-related technologies, so it should be said that there is basically no. In a short period of time, it is impossible to carry out large-scale transformations for 033s.

However, as guards and assassins in the shadows, as long as they exist, they are a kind of restraining force.

If the enemy wants to find a submarine, they may need to send a fleet, and then all the ships around will be panic and messy.

However, Xu Xingchen did not understand the specific submarine tactics and could not directly guide and direct their operations. Of course, he would not forcefully interfere.

Xu Xingchen and his friends became familiar with the environment. After they arranged accommodation, they asked them to decide what they should do according to their dream memory experience.

My job is to wait for it to be harvested, build it, update a generation of submarines, or analyze new submarine technologies, and upgrade their equipment.
