Lin Yuan left Toushanman's house, and as soon as he arrived home, he saw Wan'er running in a hurry, and she said, "My lord, something big has happened, go and take a look." ”

Lin Yuan had never seen Guan'er so panicked, and hurriedly asked, "What's wrong?" ”

Guan'er said: "When I was at Lafayette's today, I heard from the eunuchs that the emperor was so angry today that he didn't even eat lunch, and he scolded several ministers of military aircraft. ”

Lin Yuan thought to himself: "This emperor is in a bad mood, what does it have to do with me." So he said, "This emperor is angry, what can I do?" ”

Wan'er hurriedly said: "Eh, my mouth is too stupid, I didn't explain it, the emperor is angry because of you!" ”

Lin Yuan asked in surprise: "Because of me, where did I provoke him?" ”

Guan'er said: "I heard those eunuchs say, last night, Liu Kun, the governor of Liangjiang, went to a fold, which seemed to say that the ministers of the court were nepotistic, especially the Tianjin Machinery Bureau, there were many people who ate empty salaries, and they said that you also arranged people inside, so the emperor was very angry, he had already sent people to the Tianjin Machinery Bureau, and he wanted to punish the people who ate empty salaries!" ”

Lin Yuan thought to himself: "It's better to cure their crimes, so that the output of the Tianjin Machinery Bureau may be able to come up some, and the people I arranged to go in are not empty salaries!" If they knew the true level of Luo Chaoying, they would have to offer him! ”

Seeing Lin Yuan's relaxed face, Guan'er couldn't help but say anxiously: "My lord, why aren't you in a hurry, the emperor is angry, he said that he thought you were loyal to the country, who would have thought that you were also a traitorous minister......"

Lin Yuan interrupted her with a smile and said, "It's okay, you don't have to worry, I'll go to the Tianjin Machinery Bureau to have a look." ”

By the time Lin Yuan came to the Tianjin Machinery Bureau, there were already many soldiers surrounding the Machinery Bureau, and an officer was standing at the door with a sword.

That Su Mao's face was full of panic, but his heart was extremely happy, he knew that all this was provoked by him, he begged the officer in a panic, and said: "My lord, what's the matter, why are there so many military masters?" ”

The complement of the officer's robe is embroidered with a majestic lion, indicating that he is a second-class military attaché, a small chief engineer of the Machinery Bureau, where will he put it! So he ignored Su Mao, and watched coldly as those soldiers brought people out of the machine bureau one by one.

Lin Yuan walked up to the officer and asked, "This lord, I don't know what to call him?" ”

Seeing that it was Lin Yuan, the officer hurriedly turned over and dismounted, and saluted before speaking: "I am sent by the Holy Lord, and I came to the Tianjin Machinery Bureau to investigate the people who have no skills but occupy high positions." ”

At this moment, a man who was brought out by the soldiers shouted angrily as he walked: "You dare to come and arrest me, do you know who I am?" ”

The soldier was annoyed by his noise, picked up his sword, and struck him the back, and the man was so beaten that he fainted, and the group of people who were all clamoring and shouting, and when they saw this scene, they all shut their mouths.

The officer smiled at Lin Yuan and said, "The Holy Lord must be thoroughly aware of this matter, so that we don't have to be soft!" ”

Lin Yuan was a little worried about the old professor Luo Chaoying, after all, he was old, such a toss, I don't know if the old bones of Lu Dao can bear it, so Lin Yuan searched for Luo Chaoying's shadow in the crowd, but he didn't find it after looking at it for a long time.

At this time, the officer said to Lin Yuan: "Lord Lin, if your subordinates want to go in and search in person, they will not accompany you." ”

Lin Yuan also followed, Su Mao also followed, and the group went to several places without seeing Luo Chaoying's shadow, and when they walked to the easternmost part of the factory, they saw a courtyard from a distance.

The officer asked Su Mao, "What does that courtyard do?" ”

Su Mao replied: "If you go back to your lordship, it is the artillery design department of our Machinery Bureau, and we mostly imitate other people's artillery, and almost none of our own designs are designed, so we put the design office in such a remote place." ”

The officer nodded, and didn't ask Lin Yuan what he meant, a few soldiers pushed open the door, and everyone went inside, and as soon as they entered the courtyard, they heard a young ** in the main room shouting: "Old man, don't make trouble here, you can go back and rest." ”

After that, everyone heard an old man's voice, which was full of helplessness, and the old man said: "I have told you three times, you can't design the gun barrel like that, you can't assume that the pressure on the inner wall of the artillery barrel is the same at every moment, you have to consider the influence of the temperature of the propellant, so the pressure on the inner wall is high in some places, and the pressure in some places is small." ”

The young man smiled and said, "Old man, few people in the Qing Kingdom understand the design of this artillery, can you understand it?" ”

Lin Yuan listened to the old man's voice, it was Luo Chaoying, so he was relieved, they entered the house, Su Mao seemed to be reminding the officer, and said to Luo Chaoying: "Old Luo, why are you here?" ”

As soon as the officer heard that this person's surname was Luo, he glanced at the list in his hand, looked at Luo Chaoying and shouted, "Luo Chaoying? ”

Luo Chaoying is Taishan Beidou in the field of domestic gun design, coupled with his advanced age, I am afraid that few people in China dare to call his name so unceremoniously, Lin Yuan hurriedly walked up to Luo Chaoying, and said with a smile: "Luo Lao, you are angry......

The officer shouted angrily: "Take it away! ”

Lin Yuan was just about to stop it, but the officer sneered and said to Lin Yuan: "Lin Yuan, the Holy Governor said that you arranged idlers in the machine bureau, Long Yan was furious, your good days are over!" I can't move you today, you wait, someone will come to settle accounts with you soon! ”

Luo Chaoying was stunned for a moment and said with a smile: "You say I'm an idler?" ”

After speaking, Luo Chaoying laughed a few times, walked up to Su Mao, and asked with a smile: "Do you know that the body tube you designed is not strong enough and has a low lifespan?" ”

When Su Mao heard this, he felt as if he had been struck by lightning, and thought to himself, "How can he know these things?" Su Mao said: "This is not bad for us, the quality of the steel we can use is not good." ”

Luo Chaoying shook his head in disappointment and said, "Don't pass the responsibility on to others if you can't do it yourself, let me ask you, since the quality of steel is not good, why don't you use multi-layer body management techniques?" ”

The barrel of the artillery is often composed of several cylinders, and the outer cylinder will give an initial stress to the inner layer, which can improve the strength of the inner barrel, such as the barrel of the coastal defense gun purchased from Germany in 1891 is composed of six cylinders.

Su Mao said helplessly: "We can do multi-layer body management, but our technical level is limited, and we are too slow to do it." ”

Luo Chaoying asked again: "What about the tight tube?" ”

The wire tight tube refers to the steel wire or steel belt wrapped around the barrel of the gun, these steel wires or steel belts can provide an inward pressure to the body tube, so as to improve the strength of the body tube, in the Qing Dynasty, the artillery produced by this process is also called the wire winding gun.

Su Mao said: "We can't do this silk winding process, and the accuracy of using this kind of cannon is often poor." ”

Luo Chaoying smiled: "I have a way to solve your difficulties." ”
