Daily life with the ship girl

Four deep-sea fleets?

Li Ran was stunned for a moment, then said:

"The first strike formation, the second strike formation, the first expedition formation, and the second expedition formation will each use the following people as their flagships. The first strike formation's flagship is Helena, the second strike formation's flagship is Rodney, the first expedition formation's flagship is Pinghai, and the second expedition formation's flagship is Renown. Team members will be selected based on their usual tacit understanding. Lexington and Saratoga will remain in the garrison."

"Understood." The ship girls in the exclusive channel responded one after another.

Bismarck was a little anxious, and she asked quickly:

"What about my mission?"

Li Ran heard Bismarck say this, then thought about it, contacted Nuremberg alone and said:

"Nuremberg, gather Z24, Z28, U47, U96 and others and go to the eastern harbor. Our defense there is weak. Bismarck, go there immediately. This is the fifth special support force. However, you can only act after receiving support signals from other teams. Do you understand?"

"Understood, Admiral, I'll go first. Be careful on your way back."

"Don't worry." Li Ran nodded and said.

So, the two of them acted separately. When Li Ran returned to the garrison, everyone had already attacked, and only Lexington and Saratoga were waiting for him.

Seeing Li Ran coming back, Lexington hurried over to greet him, spread the sea chart on the cleaned table, and said:

"Admiral, according to Helena's report just now, the four deep-sea monsters attacked in four directions. In fact, one direction is not within the known sea area."

"What do you mean?" Li Ran was stunned for a moment, then looked at the nautical chart and saw that Lexington's baton was pointing to an unknown sea area.

Li Ran was stunned for a while, then said:

"You mean the uncharted waters? The east? The direction of our eastern harbor. Who is leading the fleet in that direction?"

"Ping Hai and the others, because isn't the east the safest?"

"Not good." Li Ran immediately contacted Bismarck through the admiral's personal network, and then said:

"Pay attention, the deep-sea fleet in the eastern waters is likely to come from unknown waters. You are going to attack directly with the second expeditionary formation. I have a bad feeling."

Bismarck nodded, and then responded: "I understand, Admiral. We are about to go to sea. If there is anything, remember to contact Haierduo."

"Hey Erduo, by the way, did anyone else take the equipment out?" Bismarck heard the other end hang up the call, and immediately asked Lexington, only to hear her say:

"It seems that everyone except Ping Hai has brought it."

"Well, it seems that the number of equipment is still not enough." Li Ran felt that this might be the case. He carried a Sea Ear with him, Bismarck also had one, and the other three were left in the port area. Now the number of equipment was indeed not enough.

Lexington nodded, then hesitated for a moment and said:

"Admiral, I was just thinking of finding a time to report to you about the unknown waters, but I didn't expect the deep sea to come knocking on my door again so soon today."

"Again? Could it be that when I was not at the port, there were also deep-sea attacks on the port in unknown waters?"

Saratoga curled her lips:

"Of course, why do you think everyone is..."

Lexington coughed and said:

"Gaga!"

Seeing Lexington like this, Li Ran felt that something was wrong. It seemed that Lexington was hiding something from him. He was about to ask, and then he heard the report:

"Admiral, it's bad. Radar shows that a large-scale deep-sea fleet has appeared in the eastern waters. A large-scale deep-sea fleet has appeared in the eastern waters!"

The one who reported was Helena, who was in charge of the south, which was adjacent to the three islands. However, being good at intelligence analysis, she immediately used her ship-mounted radar to explore the port area. Sure enough, she found a suspicious signal in the eastern waters at the limit of her radar's range.

"What?!" Li Ran was wearing a Haier communicator, and when he heard the report, he was stunned.

Chapter 225: Triangulation

Although Li Ran was worried, he had checked the status of each ship girl before. Although their training level had not exceeded level 50, compared to the fact that so many ship girls were dispatched together this time, there shouldn't be any big problems.

At night, if there are no aircraft carriers involved, there might be some trouble.

Lexington watched the admiral fall silent, she was a little worried:

"Admiral, it would be better if it was morning now. If the children could attack, they could also support the sisters."

Li Ran heard the reluctance in Lexington's words. He thought for a moment and then said:

"It's not impossible to launch carrier-based aircraft at night, but let's forget about it for now. You and Gaga have worked hard. By the way, how about Raider and Brooklyn?"

When Lexington heard Li Ran say this, she was a little bit unbelievable and automatically ignored the question behind it. Then she looked at the admiral with expectation and said:

"Admiral, do you have a way to allow the children to attack at night?"

Li Ran thought about it. As for night vision radar, although it is not in the game, if the goblins have the technology level to build a transformation core, it should be no problem to carry out the magic modification of the ship equipment. However, this matter requires long-term planning. Although he is a member of the Marine Corps, he does not know much about the principles of night vision radar. He thought for a while:

"Well, but I don't know if it will succeed. Let's not talk about that for now. Have Raider and Brooklyn and the others returned to the academy?"

"Yes, they went back. The admiral must be very disappointed." Saratoga said with some resentment.

Li Ran was choked and felt a little embarrassed.

Lexington tapped his sister on the head and said:

"Don't talk nonsense, the Raiders and Brooklyn helped us a lot."

Li Ran felt a little regretful. After all, Brooklyn was Helena's sister. She would be very happy to be able to stay. Moreover, if the Raider, as a light mother, could also stay, the port's anti-submarine warfare capabilities would be greatly improved. He said helplessly:

"We're going back. Well, let's not talk about this for now. If they are fighting now, we can't be lazy."

Lexington heard what Li Ran said and was about to get up, but Li Ran's communicator flashed a rapid signal light. Saratoga was a little curious:

"Admiral, look at that device flashing."

Li Ran was stunned for a moment, and saw the Haier Communicator he had just taken off. This was the first time he saw the signal light flashing so quickly. He put it on quickly, and after the call was connected, he heard Bismarck's exclamation from the other end:

"Admiral, something terrible is happening. I am now 165 nautical miles from the eastern coast of the port area, coordinates 1148°51'40''N, 112°20'09''E. A large-scale deep-sea fleet is gathering in the eastern waters. Requesting reinforcements!"

"What!" Li Ran was dumbfounded, then he forced himself to calm down and said calmly:

"Hold on for now. If all else fails, retreat to the reef area in the center of the three islands. I'll have Helena and the others reinforce you immediately."

"Understood." Bismarck nodded solemnly and hung up the phone.

Lexington and Saratoga looked at each other, watching Li Ran continue to deploy the battle plan after hanging up the phone, and they did not dare to disturb him.

It was not until Li Ran had issued all the orders that Lexington hesitated whether to ask.

Li Ran frowned, but was a little surprised that Lexington and the others didn't ask. Then he looked over and saw the worry on their faces. He had to force a smile:

"It's okay, there are just more deep sea fleets."

Lexington gritted her teeth, then thought about it and decided not to ask about the specific situation. Although she was a secretary ship, it was not easy to interfere with the admiral's judgment in some situations, especially in the middle of a major war. She had no experience in night battles, and she would never interfere in matters she was not good at.

Lexington gave up the idea, and when she saw her sister was about to ask, she immediately interrupted:

"Jia Jia, go upstairs and get the project plan we wrote these days."

"But……"

"Go quickly."

……

Li Ran was a little confused, but now was not the time to think about it. He saw Jia Jia go upstairs and said to Lexington:

"Help me get the scale and the triangle for surveying. I need to do triangulation to determine the approximate sea area where Bismarck and the others had a fierce battle. Since we have already started a battle, we have to find where the enemy is attacking. I don't believe that all four directions are the main attack points. Since the eastern sea area has been confirmed to be the source of the enemy, we have to do something for them."

"Admiral, you mean triangulation?"

"Yes, what's wrong?"

"Nothing... nothing." Lexington sighed, thinking he might have been overthinking.

"Well, I'll do some simple measurements first. Can you please get the tools for me?" Li Ran didn't have time to think about it. After all, it was combat time. He didn't think much about it and continued to calculate the approximate coordinate range of Bismarck on the nautical chart.

Lexington walked forward with a lot on his mind and almost bumped into his sister who was coming down the stairs.

"Sister? What's wrong with you?" Gaga quickly took a small step back.

"It's okay, I'll go get the tools. The Admiral must be very upset right now. Some things can be discussed after the war, okay?"

"I know, I know." Saratoga did not talk back this time. She held a pile of business plans and watched her sister hurried upstairs with some worry. This was completely different from her usual calm and unhurried sister. She sighed softly and was about to shout when she saw Li Ran leaning over the nautical chart, drawing something with a pencil and ruler in his hands. She did not interrupt him carelessly, but gently placed the business plans on the chair next to her.

Although she was still somewhat unwilling to accept Li Ran's attitude towards her sister, he was an admiral after all. After thinking for a while, she silently walked aside to make a cup of coffee.

After waiting for a while, Lexington took some surveying tools downstairs and said to Li Ran softly:

"Admiral, here you go."

Li Ran nodded, then looked at the tools which looked quite professional. He was very satisfied. The higher the precision of the measuring tools, the more accurate the results of surveying and calculations would be.

Li Ran was measuring the area in the eastern sea area, and then he said without raising his head:

"By the way, where did these tools come from?"

"Admiral, do you still remember that geographical survey team? A report was submitted this afternoon. In fact, the Admiral Academy headquarters funded the geographical survey team. Their goal was to calculate the situation of the newly discovered islands in the marginal sea area, so they provided us with these professional surveying tools."

"That's great! The more accurate the tool is, the more accurate the result will be."

As Li Ran spoke, he took a piece of draft paper next to him, thought for a while with a pencil, and began to calculate the coordinates and convert the scale.

About half an hour later, Li Ran breathed a sigh of relief, because he finally figured out the approximate range of Bismarck:

"You see, the area of ​​the Great Triangle is the sea area where they are located, but this only narrows down the scope. For further calculation, I will ask Bismarck."

Lexington looked at the manuscripts on the table, which were filled with formulas that she could not understand, as well as some strange geometric figures. She looked at the large triangle drawn by the admiral with a pencil on the nautical chart and was stunned. How could he have calculated it so quickly?

Li Ran immediately dialed the number:

"Bismarck, where are you now? Please report the changed coordinates."

"I see." Bismarck said briefly, then seemed to ask, after a while, and then said:

“距离港区东部海岸105海里，坐标变更为坐标1198°51'40''N，152°20'09''E”。”

"Understood. You all must be careful. If you are defeated, you are allowed to retreat tactically. That's it for now." Li Ran nodded. He could vaguely hear a few footsteps coming from the opposite side. He knew that he could not delay the battle of Bismarck and others. After writing down the coordinates, he hung up the communication and made the final precise calculations.

"Their movement trajectory is like this. So, if we move forward, the direction from the deep sea in the eastern waters should be determined to be in the northeast. By the way, ask Helena if they have found anything strange on the radar."

Lexington and Saratoga watched Li Ran calculating, putting down his pen to think, and talking to himself. They could only wait quietly by the side, not daring to disturb him for fear of affecting Li Ran's calculations.

Chapter 226: Pachino Fortress——Pachina

Li Ran didn't care whether Lexington and the others understood or not. To be honest, the triangulation method was originally used more in astronomy, but he happened to have learned some of it. The calculations were not very fast, but he was still quite confident in the results.

After the approximate range was calculated, it was time to narrow it down. Without a computer and satellite positioning, the coordinates would inevitably have deviations, so I still had to ask Helena about the location where the deep-sea fleet she discovered first appeared in the eastern waters.

However, Li Ran's use of the [Sea Ear 1-5] ocean-going combat communication equipment failed this time, as extremely strong interference was transmitted from the equipment.

"Hello? Helena, can you hear me? Helena? Helena!"

Li Ran yelled for a while, and found that there was no response from the other end of the device. Just as Li Ran was about to connect to other people's communication, the interference signal stopped, and suddenly a very ethereal voice came:

"Long time no see, Admiral."

"who are you?"

"Oh, have you forgotten me after not seeing me for a year? You are so heartless."

Lexington looked at Li Ran who suddenly stood up with an unhappy expression on his face. Although he wanted to ask, he held back.

Lexington did this because she didn't want to disturb Li Ran's thinking. As a secretary ship, there are some things that the admiral doesn't allow her to ask. As a ship girl, she can't ask rashly. This is Lexington's self-awareness.

Li Ran's forehead was covered with sweat. He felt something was wrong. It was a year ago again. Could it be related to what Helena said? Damn it, what happened in this world during the time when he gave up?

Moreover, Li Ran always felt that he had heard this voice in the game. He swallowed his saliva:

"who are you?"

"That's not what you said when you pushed me down. Now, I'll let you lose everything again this time. I'll take away everything you have, so you won't run away again, right~"

Li Ran felt a chill down his spine. He tried to calm himself down, then asked in a deep voice:

"who are you?"

"Are you serious now?"

Li Ran stopped talking and waited for the other party to speak.

"It's really boring. Since you've been away for a year, why do you suddenly come back?"

After that, the other party hung up the call, and then Helena's voice came, and the voice revealed an extremely anxious mood:
