Ling Xue didn't know the history of the development of submarines, and when she heard Lin Fei say about submarines, she felt extremely mysterious and fearful, and asked cautiously: "This submarine sounds so powerful, can we build it?" ”

Lin Fei nodded seriously and said: "This type of submarine I designed is not complicated, the length of the submarine is only 15 meters, the displacement is only 50 tons, and the diving depth is only 4 meters to 5 meters, the water pressure at this depth is not large, so there is no need to specialize in smelting special pressure-resistant steel, it is enough to use our existing steel." ”

"Submarine power, we have batteries, as for internal combustion engines, we have purchased a batch before, handed over to the national design institute and factory for research, they can be equipped in submarines." Modern conventionally powered submarines have two power systems, one with an internal combustion engine and one with a battery.

The reason for this design is that the battery has good concealment and poor continuity, while the gasoline engine has poor concealment and good continuity, because the gasoline engine needs air to participate when working, and the submarine either surfaces or uses a snorkel, which is easy to be discovered by the enemy. By using two power systems at the same time, you can complement each other's strengths.

"Submarine armament, we have captured Spanish torpedoes, which can be used completely, as for the sighting system, we have optical glass, which can already make telescopes, and it is not difficult to make periscopes. We can build submarines. ”

Lin Fei deliberately concealed the communication and navigation system and did not say that one of the important reasons why submarines were not taken seriously in this era was...... Without a proper communication and navigation system, as soon as the submarine dives underwater, it does not know its location, and in this era there is no sonar communication equipment, and the submarine commander can no longer find it as soon as he gets out of the water.

If a submarine wants to complete navigation and communication, it must sail on the surface, but the submarine has no combat value when it sails on the surface, so all countries in the world disdain submarines.

This situation was not alleviated until the beginning of the twentieth century, when gyroscopes and radios appeared, and with gyroscopes there were inertial navigation systems, and submarines could complete autonomous underwater navigation; With radio, the submarine was able to communicate with the commander only when it surfaced.

Communication and navigation are too advanced, Lin Fei felt that it was useless to tell Ling Xue, so he didn't say it, Ling Xue didn't ask, and when he heard Lin Fei say that the submarine could be built completely, he smiled, urging Lin Fei to taste her craftsmanship and rest quickly after eating......

In the next day, Lin Fei dismantled the submarine into various subsystems, handed it over to the National Design Institute for design, and then, accompanied by Ling Xue, went to inspect the gyroscope development factory.

Gyroscope is a very important element in weapons and equipment, inertial navigation equipment made of gyroscope as an element, can make the torpedo shoot farther, so that the submarine does not lose its way underwater, Lin Fei wants to build a submarine, but also wants to make the submarine fight, the gyroscope is an indispensable element.

In charge of manufacturing the gyroscope were several experienced fitters, who built the various parts of the gyroscope according to the drawings given to them by Lin Fei, and then assembled the parts together.

After the gyroscope was manufactured, several graduates of Huaxia University tested the gyroscope and obtained various numbers of gyroscopes.

Lin Fei brought the person in charge and asked about the performance of the gyroscope, and the answer he got surprised Lin Fei very much, the drift error of the gyroscope is very large, and it has not been able to be reduced, which means that the inertial navigation system made with this gyroscope as the core element is not accurate, and it must be corrected every fifty nautical miles.

This is nothing to surface ships, they can always use the means of astronomical navigation to correct the gyroscopes on the surface, but for the submarines, they must first surface if they want to correct the gyroscopes, and if the submarines surface from time to time, then there is no concealment at all.

Lin Fei realized that with the performance of the current type of submarine, it must not be allowed to fight alone, so Lin Fei decided to design a tow line on the submarine, let the battleship tow the submarine, and when the time was ripe, release the submarine to launch an attack on the British Sovereign-class battleship.

Lin Fei had arranged the construction of the submarine properly, and selected the submarine operator from the Naval Officer Academy, and Lin Fei had already decided to use the battleship to tow the submarine forward, so the training subjects were greatly simplified.

While Lin Fei was actively preparing for the submarine, the diplomatic confrontation with Claros was not delayed, Lin Fei did not show that he had seen through the tricks of the British, and was grateful to Claros for his help, and the atmosphere of the talks between the two sides was very harmonious, and Lin Fei also successfully persuaded Claros to send a monarch-class battleship to deter the Dutch.

The time came on January 5, 1896, and after more than ten days of construction day and night, the submarine designed by Lin Fei finally sailed into the sea, and Lin Fei named it "Ghost Shark".

The reason why this submarine can be built in just a dozen days is because this type of submarine has a simple structure, all kinds of subsystem components are very mature, and in Lin Fei's tactical vision, the Ghost Shark has always been towed by the battleship, and only at the last moment will it fight independently for a while, so the preparations are simple.

In the past ten days, Claros has continued to send news that the anti-Chinese riots are about to occur, and the situation in Pontianak is already full of rain.

The time came on January 8th, at 8 o'clock in the morning, the British Reuters news agency in Dayu City suddenly received a shocking news, at 9 o'clock in the evening of January 7th, there was a riot in Pontianak, two Chinese shops on the street were smashed, and the rioters also attacked the rich Chinese area, and the casualties are still unknown.

Claros urgently asked to see Lin Fei, and as soon as they met, he said to Lin Fei: "Mr. Lin Fei, what happened last night is just a prelude, I believe that a larger anti-China wave is still to come, should you take action?" ”

Lin Fei replied in a deep voice: "Yes, I must take action, I plan to send the Tianlong Ship and the Yunlong Ship to the waters near Pontianak to evacuate the Chinese in Pontianak." ”

Claros frowned and said, "There are more than 200,000 Chinese in Pontianak, and you only send two cruisers, is it enough?" ”

Lin Fei sneered in his heart, what a Claros, you are afraid that we will not fight fiercely with the Dutch, and you want me to send more troops, okay, then I will fulfill your wish... Lin Fei then smiled and said: "The two cruisers are just advance troops, after all, Dayu City is far away from Pontianak, and the cruiser's speed is relatively fast, so it can be reached as much as possible, and the slower troop carrier follows behind and arrives later." ”

Claros smiled with satisfaction and said, "In order to facilitate the communication between our two countries, I intend to go to Pontianak on the same warship with you. ”

Lin Fei planned to use the Celestial Dragon Ship to tow the submarine forward, if Claros was on the Celestial Dragon, he would definitely find the submarine, and in that case, Lin Fei's plan would be all in vain.

Lin Fei then shook his head and smiled: "I'm really sorry, Mr. Claros, the Tianlong Ship is our flagship and the most elite naval force in the Empire, we will not let outsiders on the ship, please forgive me." ”

Claros didn't insist, smiled and agreed, said goodbye and went back, as soon as Claros left, a subordinate reported: "Liu Ziyu asks to see." ”

Lin Fei asked Liu Ziyu to come in, at this time, Liu Ziyu's eyes were red, his face was full of anxiety, and when he saw Lin Fei, he said: "Your Majesty, I heard the news, the Dutch and the natives have already attacked us Chinese, if you don't rescue them, they will all ......."

Liu Ziyu sobbed as she spoke, and Lin Fei said with a smile: "You don't have to be sad, I have already decided to send troops to rescue them." ”

Liu Ziyu burst into tears and laughed, and said excitedly: "Great, now we are saved, Your Majesty, let me go with your troops." ”

Lin Fei hesitated for a moment and said, "The battlefield is too dangerous, you are a girl, I'm afraid it's not appropriate to go." ”

Liu Ziyu frowned, and said: "Your Majesty, although I am a girl, I am also a warrior, a Chinese warrior..."

Seeing Liu Ziyu so resolute, Lin Fei nodded and said, "Okay, I agree with you to go to Pontianak, but there is one thing, you and your people will follow me in the future, and you are not allowed to go anywhere." ”

Liu Ziyu asked in surprise, "Your Majesty, do you want to go in person?" ”

Originally, Lin Fei didn't need to go in person, but this time Lin Fei wanted to send a submarine to carry out the plan to provoke war between Britain and the Netherlands, so he had to go in person, Lin Fei didn't say these things to Liu Ziyu, just smiled and nodded, and said, "That's right, I'll go in person this time." ”

Liu Ziyu burst into tears with excitement, choked up and said: "Emperor Fei personally went out, we Chinese will never be bullied again......

Lin Fei looked at Liu Ziyu, and suddenly thought of what Ling Xue said that day about letting Liu Ziyu pretend to be Chiyo Mika's sister, Lin Fei set the departure time on January 11, that is, two days later, so there was plenty of time, so Lin Fei decided that before leaving for Pontianak, let Liu Ziyu pretend to be Chiyo Mika's sister and talk to Chiyo Mika, maybe it would be good for her illness.

Lin Fei then smiled and said, "Miss Ziyu, I have something I want to ask you for help. ”

Liu Ziyu chuckled and said, "Your Majesty, don't be so polite, you are my great benefactor, and I am willing to do whatever you ask me to do." ”

Liu Ziyu lowered her head shyly as she spoke, Lin Fei's expression darkened, and she said, "Do you remember the thing I called you Meixiang when I first met you?" ”

Liu Ziyu nodded and said with a smile: "Of course I remember, not only you, but Concubine Xue also called me Meixiang, I have been thinking these days, who is Meixiang?" Do I look like her? ”

Lin Fei lowered his head and sighed sadly, "Meixiang is a hard-working girl, and you do look very similar to her, so Xue'er and I mistook you." ”

(Wireless has a recommendation, so add a change these days)
