Lin Fei saw that the guard's expression was wrong, and knew that he had something to say, so he smiled at Yu Xi'er and said, "Old Yu, you go back first, I'm really sorry for this incident." ”

Yu Xi'er smiled open-mindedly, said a few "It's okay", turned around and walked out, Lin Fei waved his hand to call the guard to him, and asked, "Do you have something to tell me?" ”

The guard hesitated for a moment, then said, "I do have a situation to report to you. ”

Lin Fei said: "Don't hesitate, just say it." ”

The guard then said: "Report to Your Majesty, when I went to Minister Ling's office to ask for the visitor's record, the doorman looked very nervous, I asked him what he was nervous about, he was hesitant for a while, his expression was very unnatural, and then he told me, he heard that Your Majesty Xià you want to see what he recorded, so he was nervous, this reason is obviously unreasonable, I think this matter is very strange, so I sued you." ”

Lin Fei frowned and said, "I see what he is so nervous about what he recorded, there must be something wrong with his words." What is the name of this doorman and what is his origin? ”

"His name is Zhang Dafan, and he turned out to be the doorman of the Ling Ji Manufacturing Bureau." The guard replied.

Lin Fei frowned, pondering silently, "Your Majesty, do you want us to arrest him and interrogate him?" The guard said.

"No, we don't know anything now, and arresting someone rashly will only cause unnecessary panic, so you keep that doorman in the eye on me, and you don't let go of the slightest move, including where he went when he got home from work, who he saw, etc." Lin Fei said.

"Yes, your majesty, your subordinates understand." The guard said yes and turned to leave.

Lin Fei saw that the search for the traitor was at an impasse, so he immediately decided to put this matter aside for a while and concentrate on formulating the next stage of the military development plan.

Lin Fei's main combat object now is Britain and France, although Britain and France are also rivals in this era, fighting with each other, and there is a feud such as the Hundred Years War between Britain and France, but on the issue of foreign aggression, the interests of the two countries are still highly unified, in the second Opium War, Britain and France united to invade the Qing Dynasty, and also burned down the Old Summer Palace, plundered a large number of cultural relics, and left an indelible wound in the hearts of every descendant of Yan and Huang.

At war with Britain and France, the main battlefield was at sea, so Lin Fei decided to develop two killer weapons to ensure victory in the naval battle.

The first killer weapon is the submarine, the Ghost Shark submarine has been tested in Pontianak, and the next step is to build a submarine capable of autonomous combat.

Although submarines have appeared in this era, military strategists from all over the world have not yet realized the huge military value of submarines and have sneered at submarines.

At present, the development of submarines is mainly stuck in the following key points: First, the level of gyroscopes is not up to standard, the ability of submarine navigation is extremely poor, and the gyroscopes also affect torpedoes.

On modern torpedoes, the gyroscope is an important element to keep the torpedo course stable, only when the course is kept stable, the torpedo range can be greatly improved, and the submarine's combat is meaningful, otherwise the submarine needs to launch the torpedo under the nose of the enemy ship, which is simply a suicide attack, and now the gyroscope produced by the Chinese Empire is still too large to fit into the torpedo,

Second, the performance of pressure-resistant steel is not up to par, the depth of the ghost shark boat is only 20 meters, and it can only barely be discovered; if it wants to fight independently, the enemy's reconnaissance intensity is bound to increase, and the depth of 20 meters is not safe, and the depth of diving must reach at least 50 meters, or even greater.

Third, the detection technology is not up to par, because the attenuation of electromagnetic waves propagating underwater is extremely large, and the detection target of the submarine can only rely on sound waves, so the submarine must be equipped with sonar, but now the Chinese Empire has not developed sonar, so Lin Fei decided to design and manufacture the simplest sonar first...... Hydrophones.

The second killer weapon is the "fully armed heavy artillery" battleship, that is, the famous dreadnought in the Lin Fei era, the dreadnought is a battleship, the battleships built before the dreadnought are equipped with large-caliber main guns and medium-caliber secondary guns, and on the dreadnought, the medium-caliber secondary guns are canceled, and the free displacement and space are used to equip more large-caliber main guns of the same caliber.

The advantage of this is obvious, the caliber of the naval guns is the same, the ballistics are also the same, the ballistics can be solved uniformly, and the guns can be fired at the same time, which is how the most exciting "sideboard salvo, 10,000 guns in unison" of the battleship era came from.

The dreadnought's shells can hit the target at a very long distance, and with the advanced fire control system, this hit distance can reach 10,000 meters, 20,000 meters or even 40,000 meters, this distance growth is revolutionary, you must know that the ship gun hit distance before the dreadnought, usually only 3,000 meters.

As soon as the powerful dreadnoughts got out of the water, the battleships built by countries around the world instantly entered the museum, and all countries built battleships equipped with large-caliber guns of the same caliber, and collectively called these battleships "dreadnoughts", and the battleships produced before were called "former dreadnoughts".

In Lin Fei's era, the dreadnought was the first to be built by the British, but in this era, the first person to build a dreadnought would be Lin Fei, and Lin Fei decided to build a type of battleship with a standard displacement of 13,000 tons, equipped with ten 280 mm heavy guns, and no longer equipped with secondary guns.

This will be the first type of battleship of the Chinese Empire, and with this type of battleship, at least it will have the capital to wrestle with the British monarch-class and the French Charle-Martel-class battleships.

However, the development of this type of battleship is also extremely difficult, first of all, the displacement, the displacement of 13,000 tons puts forward a lot of requirements for the mechanical properties of the hull steel, followed by the naval gun, the difficulty of the development of the 280 mm naval gun is not low, don't look at the increase from 240 mm to 280 mm, the increase is not large, but the technical difficulty has to go up several steps.

Lin Fei sorted out all aspects of the preparatory work, the technical aspect was solved by the talents of the National Design Institute led by himself, the manufacturing aspect was solved by the skilled craftsmen recruited from the Qing State and trained by himself, and in terms of materials, submarines and dreadnoughts needed a lot of materials, and the mineral resources in the Nanyang region may not be able to support it.

For example, in the manufacture of hydrophones, piezoelectric crystals are required for hydrophones...... Quartz, although quartz is a relatively easy thing to obtain, but the high-quality quartz that can be used to make hydrophones can only be obtained from the Qing Kingdom, as well as the various quenching and tempering elements needed to produce high-performance pressure-resistant steel, and its ore must also be purchased from the Qing Kingdom.

It can be seen that without the resources of the Qing State as the backing, Lin Fei's Huaxia Empire will not be able to develop for a day.

Lin Fei then formulated a huge plan for the purchase of materials for the Qing Dynasty, and handed over this plan to the people of the Ministry of Commerce to implement, in order to make this purchase plan go smoothly, Lin Fei specially instructed Liu Yongfu, the governor of Taiwan Province, to resign from the post of governor and serve as a special adviser to the Qing State material purchase plan.

Qing people attach great importance to human feelings, Liu Yongfu has a lot of old times in the Qing Kingdom, with him, many problems can be solved, thinking of Liu Yongfu, Lin Fei naturally thought of Sa Zhenbing, Sa Zhenbing is also an old minister of the Qing court, so Lin Fei asked Sa Zhenbing to temporarily resign as vice president of the Naval Academy and join the purchase plan.

Lin Fei called the Naval Academy in Yanhuang City, and learned that Sa Zhenbing had set off from Yanhuang City to Dayu City to visit his daughter Xiyun two days ago, so Lin Fei decided to wait for Sa Zhenbing to come to Dayu City and talk to him in person.

After Lin Fei finished preparing these things, he called Liu Daming and asked, "How are the Tianlong Ship and the Cloud Dragon Ship repaired?" ”

Liu Daming said with a smile: "It's all repaired, and I'm preparing to re-enter service." ”

Lin Fei said with a smile: "Very good, go and contact the Ministry of Foreign Affairs, and ask the Ministry of Foreign Affairs to notify Britain and France and invite them to visit the Dragon-class cruiser." ”

Liu Daming laughed, "Is this the strategy you said to mislead the enemy's development?" ”

"That's right." Lin Fei said with a smile, and then laughed secretly in his heart, I am going to develop a dreadnought, the British, the French, you will run all the way to the black on the road of rapid-fire guns.

Liu Daming asked: "Then we can't show everything to others, right?" ”

"Of course, we only show them two classified weapons, one is a hydraulic retractor, the other is a cap-piercing shell, these two are enough, remember, the fire control system and trinitrotoluene explosives are not allowed to show them under any circumstances, especially the cloud burst bombs, let alone let them see, before the display, all the cloud burst bombs are unloaded from the battleship."

Liu Daming replied clearly: "Understood." ”

Lin Fei finished formulating these plans, he was in a good mood, and went back to his residence in the evening, he still remembered what Ling Xue said to Xiyun, "If you don't take care of Your Majesty, I will have a hard time", Lin Fei couldn't figure out what this sentence meant, and decided to ask Ling Xue tonight.

As soon as Lin Fei returned to his residence, he heard the cry of "woo", he hurriedly came to the bedroom, only to see Ling Xue curled up in the quilt, crying vigorously, Lin Fei walked to Ling Xue's side with a smile, patted her delicate buttocks lightly, and said with a smile: "Don't cry, isn't it just a leak, it's okay, the development direction of Sumatra Island is locked, and we still have Qing Guo to rely on." ”

Ling Xue stopped crying slightly, got out of the quilt, and said ashamedly: "But those two materials were brought out by the British, and our losses are not small." ”

Lin Fei laughed, "Isn't it just two materials, it's okay, I still know more materials, and this matter was not done by Yu Xi'er, so you are not at fault." ”

Ling Xue was taken aback and asked, "It wasn't Yu Xi'er who did it, who did it?" ”

Lin Fei shook his head lightly, and then said with a smile: "Let's not mention this matter first, let me ask you something." ”
