AD 1638 was the twentieth year of the Apocalypse in the Ming Dynasty.

Unconsciously, it has been twenty years since Zhu Youdong ascended the throne of this empire.

In the past twenty years, the Ming Dynasty has prospered and the people's lives have become better and better. Therefore, since last year, both officials and private citizens have been planning to hold a celebration for the emperor's twentieth anniversary.

Zhu Youdong seemed very indifferent to the actions of the officials and the people: If you are in the mood to do something, just do it. If you want me to be a mascot, I can attend the meeting or something, but don't expect me to be very enthusiastic. As for that,

Some flattering officials wrote a letter saying that Jin Shang's civil and military skills had surpassed those of the Han Dynasty and the Tang Dynasty. With Jin Shang's achievements, he could go to Mount Tai to be enshrined in Zen. Zhu Youdong even sneered after reading this: Such a memorial should be left unpublished.

That's for sure. Not only that, but these officials who wanted to put me on the fire were recorded in his notebook and became the focus of the next inspection in Beijing - their career was over at this point.

Huh, if he was the only traveler in this plane, he would have gone to Zen a long time ago, and why are you sycophants? It's a pity that there are still two opponents in this plane. And these two opponents are very strong!

Therefore, at the beginning of this year, Zhu Youdong, who had no idea of ​​success or fame, went to Fangshan Academy of Sciences first.

"I respectfully welcome your Majesty."

"You don't need to be polite. I've been here many times. As a rule, everyone should report on the progress of the projects they were responsible for last year and any difficulties."

"According to the decree." Xu Guangqi, who has relieved himself of the numerous affairs of the Ministry of Industry and devoted himself to managing the Fangshan Academy of Sciences, is seventy-six years old. Although thanks to the progress of medicine, his health currently looks pretty good.

But, after all, he is getting older, so he is obviously showing signs of aging.

He slowly turned around, looked around, and then said to Sun Yuanhua: "In that case, let Chuyang come first."

"Yes." Fifty-seven-year-old Sun Yuanhua came out: "Your Majesty, the firearms laboratory in charge of me has two major achievements last year. One is the success of casting a 305mm heavy cannon. This cannon is in accordance with the weapon naming rules of the Ming Dynasty.

, tentatively designated as Longteng. 25 times the caliber, the bore length is 6800mm, the entire gun body weighs 32 tons. If it is armor-piercing, each shell weighs 330 kilograms. The effective range is 8000 meters, and the maximum range can reach about 10,000 meters. After preliminary

Tests have shown that the steel plates on Ming Dynasty’s existing 5,000-ton ironclads will deform violently or even penetrate directly after one shot. Two shots will definitely penetrate them.”

"Very good. Thank you for your hard work, Mr. Sun."

"I don't dare. I am just the chief engineer of the firearms laboratory. The real and specific work is done by the young people below. To be honest, it was this young man who played a key role in the development process of the Dragon Cannon.

people."

As he spoke, Sun Yuanhua pulled a slightly nervous young man out of the queue: "Your Majesty, this person's name is Zhu Kuiyou, he is only thirty years old. During the development process of the Dragon Cannon, he successfully developed a large plate rolling machine

, this plate bending machine is the second major achievement of our firearms laboratory this year. The emergence of this new equipment has completely revolutionized our method of casting cannons. If it were not for him, we would not have been able to build such a huge cannon.

, I guess the quality is not very reliable.”

"Zhu Kuiyou? Well, are you a descendant of the King of Han?"

"Your Majesty, I am the tenth generation grandson of King Han Xian (the first king of Han in the Ming Dynasty). However, my ancestor has been the Lieutenant of Fengguo three generations ago."

"I see. Speaking of which, my clan's new policy has been implemented for twenty years. What do you think?"

"I think it is very good. When the emperor implemented the new policy of the clan, I was only ten years old. At that time, the house was full of books, but there were only a few grains of rice in the rice vat. In order to survive for the family, my father had no choice but to set up a stall on the street.

He wrote family letters to survive. Even so, he was still worried, for fear of being reported and the stall would not be able to open. After the emperor's new policy began, my father started the business of the Four Treasures of the Study in an open and honest manner, and the family soon no longer had to worry about food and clothing. In this way,

I am qualified to study and enter school."

"Hahaha, very good. Zhu Kuiyou, I am very happy to see you today."

Of course I'm happy, because such a young scientist was born entirely because of his butterfly wings. The emergence of this kind of talent shows on the one hand that his clan's policies are correct. On the other hand, it also shows that Ming Dynasty's scientific research and teaching have entered the

We are on the right track: we can continue to cultivate high-quality talents on our own.

This is completely different from the feeling that he used the foresight of time travelers to recruit scientists who are famous in the historical plane such as Xu Guangqi and Sun Yuanhua.

"Your Majesty." Seeing that the legendary majestic emperor was so kind, Zhu Kuiyou became a little more courageous: "The birth of this dragon cannon is not only due to the credit of my rolling machine. In fact,

In order to withstand the impact of nearly half a ton of artillery shells on the barrel in the future, the strength of the gun body must be high. But steel, the higher the strength, the higher the brittleness. If the brittleness is too high, the plate cannot be rolled."

"That makes sense, so how did you solve this problem?"

"This is all thanks to the materials laboratory under Her Royal Highness the Princess. They came up with a new alloy formula, which not only ensures the strength of the gun body, but also makes it tough enough to withstand rolling. At the same time, Liangfu

Sir (Wang Zheng) developed a new welding method, and this is how this giant cannon was born..."

Sure enough, the further technology develops, the greater the proportion of multi-disciplinary cooperation required. Once the research and development of a certain discipline cannot keep up, it will cause an obvious shortcoming effect.

Well, speaking of which, the Spaniards have put cannons with a caliber of over 300mm onto that 10,000-ton ship and put them into practical use. It seems that the construction of the European discipline system has also been done very well.

Thinking of this, Zhu Youdong felt a little heavy unconsciously.

Then he naturally turned his attention to Song Yingxing, who was in charge of electrical research.

"Your Majesty." Looking at Zhu Youdong's eyes, Song Yingxing still didn't understand what Zhu Youdong meant. He quickly stood up and said: "Your Majesty, the electrical research laboratory also achieved some results last year. Well, we followed the Emperor's instructions and used tungsten

Using silk as a wick, we made a lamp that can continuously illuminate. Currently, batteries are used to provide energy, and a light bulb can continuously illuminate for more than 500 hours. We also follow the electromagnetic induction theory proposed by the emperor and use a steam turbine to drive a generator, which can continue to illuminate.

Generating electricity. However, the problem now is stuck on the current intensity and resistance. We are not sure what fixed formula exists here. These require a large amount of experiments to provide data before they can be summarized. We also follow the emperor's instructions

It reminds me that the transformer has been pre-researched, but since the relationship between current intensity and resistance is not yet clear, the research and development of the transformer is actually somewhat futile..."

"..." After a moment of silence, Zhu Youdong let out a long sigh: "Logically, scientific research, I know very well that it has its own rules, and I can't just use orders to urge. But, Chang Geng, you heard it just now,

This Dragon Cannon is really too heavy. If the army wants to use it, it can only be loaded on a train. But even if it is a train cannon, such a heavy shell can be fired on land, which will have a great impact on the train and rails it is carrying.

The loss. Therefore, its real purpose still lies in the navy. To install such a huge cannon, the navy must have a big ship. And the big ship must be electrified."

"I know that the navy was sunk by two armored ships in America by the giant ships of the Western pirates." Song Yingxing lowered his head in shame: "Because of my incompetence, my navy officers suffered such losses, and I feel extremely sorry. I lead you.

The electrical laboratory is already working overtime..."

"Okay, Chang Geng, I don't mean to blame you. In short, research must be speeded up, but safety, the safety of scientific researchers, is always the most important thing."

"Yes, I have written it down."

After Song Yingxing retreated, Zhu Youdong looked at Fu Shan again: "How are you doing here?"

"Your Majesty." At this time, Fu Shan was no longer as jumpy as he was when he first arrived at Fangshan, and was a bit more calm: "In recent years, with the help of many colleagues, I have produced a brand new dye, and

A brand new material that can insulate electricity. Please take a look at it, Your Majesty."

He took a piece of lavender cloth and a piece of black, light but relatively strong material. After looking at it carefully for a while, Zhu Youdong nodded with satisfaction: "This lavender is the dye you mentioned?"

"Yes, Your Majesty. In recent years, I have consulted a lot of information and visited many construction sites. Finally, I found a milky white crystal in the salt mine of Ziliujing in Sichuan. This is after the local salt mine uses natural gas to boil the brine.

The condensation in the chimney has excellent plasticity. Chen originally wanted to conduct plastic research based on it. Who knew that after it was mixed with the solution, it actually appeared a lavender color, and it did not fade after being dyed on clothes, so...

…Of course, this was just an accidental discovery.”

"It's not a bad discovery by accident. After this new dye comes on the market, Fang Shan will have a lot more funds." Then Zhu Youdong carefully weighed the 'new material' that Fu Shan handed him with his hands.

Well, it felt rough in the hand, but it was light, and... He pressed lightly, and the material quickly deformed according to the direction of his hands, and finally formed an obvious white crease at the point of stress.

"Your Majesty, this thing is also extracted from chimney condensation. However, it is different from the milky white crystal mentioned above. I extracted it from the black sediment on the chimney wall of a steel plant that uses coal as fuel. After that,

After some reprocessing, I got this thing. This thing can insulate against electric current, has a certain degree of corrosion resistance to acids and alkalis, and can always maintain its shape at temperatures below 90°. It just doesn’t feel good in the hand.

, in addition, it is relatively brittle.”

"Hahaha~ Fu Shan, very good, very good. This is phenolic plastic!"

"Phenolic plastics? Your Majesty is saying that Chen has succeeded in developing plastics?"

This, of course, was successful. After Fu Shan's explanation, Zhu Youdong finally remembered: the black sediment in the chimney that uses coal as fuel contains coal tar. It contains benzene, phenol and other substances. And these

This thing is the main raw material of the phenolic plastic series!

However, compared with the polyethylene terephthalate (PET) plastic that Osman introduced a long time ago, there is still a considerable gap in physical properties and scope of use between phenolic plastics. However, Ipraxin originally

He is a professional in materials, which is incomparable. On the contrary, a scientist like Fu Shan, who became a monk by the way, came up with phenolic plastic in only seven or eight years on the basis of celluloid, which is already very remarkable!

"Very good, Fu Shan. I'm very satisfied. What do you think? Have you figured out how to name this thing? I can tell you that in addition to being used as an insulating shell for circuits when electrical research matures in the future, this thing will play an important role in all aspects of people's lives.
