"The Holy One does not want to conquer the Japanese country,"
"Then what's the purpose of attacking Japan?"
Chongzhen smiled and said: "Of course it's for money."
"Money?" Zheng Zhilong suddenly realized, "The Japanese country has a lot of money. The gold mountain in Sado, the silver mountain in Iwami, the silver mountain in Ikuno, the silver mountain in the courtyard, and the Ashio Copper Mountain have a lot of output."
"You are wrong again, Duke of Fujian." Chongzhen said with a smile, "Sado's Jinshan and Ishimi's silver output has been mined for hundreds of years, no matter how abundant the silver output is. I'm afraid there is not much gold and silver left, and some of them are about to be exhausted.
The mountains of gold and silver are not worthy of the Ming Dynasty to mobilize troops and travel across the ocean to fight against it."
Zheng Zhilong was at a loss again: "What's the reason for that?"
"Didn't I just say that it's for money." Chongzhen stopped playing riddles and went straight to the point, "Compared to several mountains of gold and silver that are about to dry up, the people of the Japanese country are actually more valuable."
"Human?" Zheng Zhilong reacted immediately.
"The Holy One is saying that the Japanese will be captured and sold to Jiangnan to work?"
After all, he is a businessman and has a sharp economic vision.
Chongzhen smiled and said: "At present, the monthly salary of small workers in eight prefectures and one state in the south of the Yangtze River has risen to 5 yuan. If we capture 10,000 Japanese people and go to work in the south of the Yangtze River, even at a 40% discount, the monthly salary will be 2 yuan.
If you can earn 20,000 yuan, if you arrest 100,000 people, it will be 200,000 yuan a month and 2.4 million yuan a year!"
"2.4 million?!" Zheng Zhilong's heart pounded.
It is enough for the navy to build another ironclad ship named Zhou Yu.
Hey, no, it should be enough to build two Zhou Yu ships.
Because the cost of building ironclad ships will only get lower and lower.
Chongzhen smiled and said: "Do you think the Duke of Fujian can do this business?"
"It can be done." Zheng Zhilong rubbed his hands and said, "It's very doable."
Chongzhen smiled and said: "Then your naval department will come up with a combat plan as soon as possible."
"I accept the decree." Zheng Zhilong agreed, and then asked, "Then I will honor you next?"
Chongzhen said: "Just take me to the dock outside Qingliangmen. I still have to go to the Gewu Branch."
Zheng Zhilong immediately led a fleet of more than a dozen warships back to the naval base outside Dinghuai Gate, and sent a bird ship with 400 materials to transport Chongzhen and a company outside Qingliang Gate.
The main force of the imperial guard brigade entered the city from Dinghuai Gate and was stationed there.
…
When Chongzhen walked into the duty room of the Gewu Department, Fang Yizhi, Song Yingxing and Pascal were talking.
Pascal said to Fang and Song: "The School of Physics is going to do some research on materials science in the near future. If you are lucky, you may have unexpected gains. Doesn't your Gewu Department need a special kind of steel?"
"Yes, yes, there is such a thing." Fang Yizhi nodded repeatedly, "It is such a thing."
Pascal said: "Then you might as well tell me what characteristics this steel needs?"
Fang Yizhi said: "First of all, it must be hard and tough enough, and more importantly, it must be wear-resistant." Xu
"Then there is heat resistance." Song Yingxing continued, "It must be able to withstand temperatures of 1,200 degrees for a long time."
"Huh, then it's really hard to find materials like yours." Pascal shrugged, "It's hard enough, tough enough, has good wear resistance, and can withstand temperatures of 1,200 degrees for a long time."
"No need to look for it, tungsten steel is suitable." A voice suddenly sounded.
"Tungsten steel?" Pascal and the other two turned their heads and saw Chongzhen walking in.
"Your Majesty." Fang Yizhi and Song Yingxing quickly stood up and bowed, and Pascal also made a chest-stroking salute to Chongzhen.
After seeing the ceremony, Pascal asked again: "Your Majesty, what is the tungsten steel you are talking about? Why haven't I heard of it?"
"You don't know?" Now it was Chongzhen's turn to be a little confused. Could it be that the element tungsten has not been discovered at this time? This would be a bit hasty. Xu
But this cannot be difficult for Chongzhen.
"It's a dark gray metal."
Chongzhen said: "It is usually accompanied by tin, zinc or lead."
"How did your Majesty know about this metal?" Pascal asked again.
"I read it from an ancient book on alchemy." Chongzhen said casually.
"The ancient book on alchemy?" Pascal and Fang Yizhi asked at the same time, "Is the ancient book still there?"
Chongzhen shook his head and said with regret: "After the liberation of the capital, I returned to the Forbidden City and saw that the Ancient and Modern Tongji Library had been burned down long ago, and all the countless ancient books collected in it were burned."
"What a pity." Pascal and Fang Yizhi stamped their feet at the same time, "What a pity!"
"But I still remember some of the content." Chongzhen said, "I'll tell you later."
Now he can use the name of this ancient book to write down the chemical knowledge he knows in a generous way.
However, Chongzhen came to Gewuke this time for electricity. He then said to Pascal and the other three: "This ancient book is really a strange book. In addition to introducing a large number of metal materials, it also introduces another mysterious substance.
.”
"What substance?" Pascal, Fang Yizhi and Song Yingxing's interests were immediately aroused.
Chongzhen smiled and asked instead: "Heavy rains in summer are often accompanied by lightning before thunder. You must have seen it before, right?"
"Of course I have seen it." Song Yingxing said without thinking, "Lightning is extremely violent. No matter whether it is people, animals or objects, once it is hit, it will turn into coke in an instant. It is no exception." Xu
"That's because too much electrical energy is released in a concentrated manner." Chongzhen said, "If a small amount of electrical energy is released slowly, electricity is actually a very magical energy that can be of great use."
"Is there still enough power?" Pascal and the others were a little confused.
"Not only is it measured, it can also be created out of nothing." Chongzhen said, "The ancient book records the method, and even drew a power generation mechanism. I will draw it for you to see."
There was a whiteboard and charcoal in the check-in room, and Chongzhen immediately drew a schematic diagram of the generator set.
It's a schematic diagram of junior high school physics, with two magnetic poles and a simple coil in the middle.
After drawing the schematic diagram, Chongzhen pointed to the coil and said: "This coil is made of thin copper wire, but the surface must be evenly coated with asphalt."
Fang Yizhi and Song Yingxing were very doubtful that this device could create lightning? Xu
This chapter is not over yet, please click on the next page to continue reading! "It never hurts to try, right." After Chongzhen finished speaking, he said to Pascal, "Tungsten steel also needs to be prepared as soon as possible."
Once the generator is built, electric lights are needed to show the magic of electrical energy. At this time, tungsten wire is needed, so tungsten metal also needs to be prepared as soon as possible.
Fang Yizhi still had some doubts.
"Your Majesty, does it really say in ancient books that lightning can be created?"
"It's much weaker lightning." Chongzhen corrected, "It can only make people's fingers numb slightly. In short, you will know when you create electricity. This thing is really magical."
"Okay." Fang Yizhi finally chose to believe Chongzhen.
At that moment, the three of them went to work separately, and Chongzhen came towards the firearms workshop again. Xu
Zhang Jimeng's Firearms Science and Technology Workshop has also moved to Qingliang Mountain, and is not far from the Gewu Science and Technology Department.
As a result, as soon as I reached the gate of the firearms workshop, I heard a burst of laughter coming from inside, and then I saw a man running around in the yard like a madman.
"Hahaha, I found a way!"
"Hahaha, I found a way!"
"Hahaha, I finally have a solution!"
Seeing this scene, Gao Qiqian and Lu Jiude quickly stood in front of Chongzhen.
However, Chongzhen had already recognized that this lunatic guy was Zhang Jimeng, the one responsible for the Firearms Department. He was a disciple of Bi Maokang, the Ming Dynasty firearms expert. He was responsible for the breech-loading cannon together with the Gewu Department. Xu
"Zhang Jimeng, why are you so happy?" Chongzhen pushed Gao Qiqian away and walked forward with a smile.
"Eh, Your Majesty?" Zhang Jimeng, who was running around, immediately stopped and then stepped forward to pay homage, "My lord, Zhang Jimeng, kowtows to you, Your Majesty."
"No need." Chongzhen said.
"I ask you, why are you so happy?"
"Blooming bombs!" Zhang Jimeng straightened his face and said, "Your Majesty, I have already figured out how to make blooming bombs, and I will definitely succeed this time. There will definitely be no problem this time!"
"Oh, really?" Chongzhen was also overjoyed when he heard this.
"Please tell me your ideas, I may be able to help you improve them." Xu
"I accept the decree." Zhang Jimeng responded, and then said, "Your Majesty, the so-called explosive bombs are not actually the first of this dynasty. They existed as early as the Song Dynasty. Later Jin Mongolians followed suit and called them Thunderbolt Cannons.
Today's folk firecrackers are actually a type of explosive bomb that can be sent into the air and then exploded."
Chongzhen nodded: "Firecrackers are indeed a kind of explosive bomb."
Zhang Jimeng said: "In this dynasty, firearms have been vigorously developed, and mortars and explosive bullets have become conventional weapons. The reason why Chengzu defeated Mongolia was that the mortars and explosive bullets of Shenji Camp played the most important role, but the mortars and bullets
The cannon has a fatal weakness compared to the Franco cannon and the Hongyi cannon, that is, the range is too short."
"In order to increase the range of a cannon, it is necessary to increase the length of the barrel and increase the air tightness of the barrel."
"But after increasing the barrel length and strengthening the air tightness, the chamber pressure and chamber temperature also increased significantly."
"The shell of the explosive bullet cannot withstand the high temperature and pressure of the gun barrel, and will explode before it comes out of the barrel. In this way, instead of killing the enemy, it will only blow up itself."
"This is the biggest technical difficulty!" Xu
Chongzhen asked: "Then how are you going to solve it?"
Zhang Jimeng said: "Imitate the concave bullet of the flintlock gun!"
The concave bullet of a flintlock gun is the Mini bullet of another world.
"Concave bullet?" Chongzhen said, "You mean to replace the hollow iron ball with a conical lead bullet and make a conical concave at the bottom of the lead bullet? This is probably not possible because the concave bullet is not insulated.
"
"No, no, no, no lead bullet is needed." Zhang Jimeng said, "We still use the hollow iron ball as the bullet, but we can put a cork under the iron ball. One end of the cork is flat to support the iron ball, and the other end faces
A conical recess is cut out inside, so when the gunpowder explodes, the conical thin edge of the cork will be stretched open by the huge bore pressure, thus tightly sticking to the wall of the cannon bore, and then the hollow shell will be combined with high temperature and high pressure.
The gas is isolated from the gas, and the cork can also be used as a buffer to prevent the hollow iron ball from being squeezed and exploded. In this way, the spent bullet will never self-destruct and can be fired smoothly!"
