After Bai Xiu resigned, Zhu Jianji immediately found rice paper and asked Dai Yi to find the Ming Dynasty's Wanbangkan map. Unfortunately, Matteo Ricci had not yet come to China, and there was no "Wanguo Tuzhi" or "Kunyu Wanguoquan".
Map", the Wanbangkan map currently used by the Ming Dynasty still has too many gaps.
But Zhu Jianji's geographical knowledge is not bad.
I searched my brain and continued to supplement it using the Wanbangkan map as a prototype. Finally, I reluctantly drew the framework of a world map, and marked the possible locations of the American continent and Australia with the word destination.
After all this work, it was already dark.
Zhu Jianji stretched out and asked Dai Yi to put away the simple version of the world map he had drawn, and give it to Bai Xiu when he came to see him after spring, so that he could sail around the world.
Crown Princess Bai Li is not here tonight...
The evil villain in Zhu Jianji's heart suddenly began to stir.
I want to be wild.
I’m going to have a silver party!
Well, Liu Qi and Li Qin were a little conservative, so they could forget about it, but Mayinur and the other three Uighur women were trained well by Nu Wen Da Shili and were very liberal.
As soon as Zhu Jianji told Dai Yi like this, Dai Yi was stunned.
I want to give advice, but I am afraid that His Highness will be angry.
In the end, I made arrangements silently.
It was night, and Zhu Jianji was having such a happy time.
The flow of life is nothing more than this.
The next day, Zhu Jianji woke up from a pile of pink legs and lotus arms. He touched his hands wantonly and did not dare to mount his horse to fight. If the news of last night reached Kunning Palace or Shoukang Palace, he would definitely be beaten by his mother and
The royal grandmother scolded her.
Furthermore, there are only exhausted oxen that do not plow the fields.
Mayinur and others exhausted themselves very much last night.
There is ample time.
As the prince of the Ming Dynasty and the future co-lord of the world, Zhu Jianji did not want to be bedridden because of indulgence like Lao Zhu.
It's late to wake up.
Then I won’t go to the Umrah meeting.
After reading for a while in the Wenhua Hall, I always felt empty in my heart, so I simply took out the simplified world map I drew last night and checked for omissions and filled in the gaps again.
Seeing that it was almost noon, a report suddenly came from outside the palace: "Your Highness, Lu Chunjing, Zhao Chuanjia, and Zhu Bi want to see you."
Zhu Jianji felt happy.
Before the expedition to Taiwan this year, he funded the establishment of the Ming Dynasty Royal Electric Power Company, with Lu Yuan's eldest son Lu Chunjing in charge, and asked Zhu Bi and Zhao Chuanjia to take iron blocks to the Leizhou Peninsula to make magnets.
Was it successful?
He hurriedly said: "Xuan!"
After a while, the three of them entered the hall and bowed.
Zhu Jianji lay down on the back of the chair, looked at Lu Chunjing with a smile, and said: "Lv Chunjing, after returning from the lonely expedition to Taiwan, he has been busy with political affairs and has no time to inspect the Ming Dynasty Royal Electric Power Company. How is the progress?"
Lu Chunjing said: "Back to Your Highness, the company headquarters has already been built. According to His Highness's plan, a large number of craftsmen who know water conservancy were recruited, and the rivers near Gyeonggi were surveyed to find the location to build the dam. We only need to wait for Your Highness's funds to be available.
Start building dams.”
Zhu Jianji nodded, "We don't have money for the time being, so we're going to wait a little longer to build the dam."
Lu Chunjing: "..."
Then what are you urging me to do?
Zhu Jianji looked at Zhu Bi and Zhao Chuanjia: "How was the result of going to Leizhou Peninsula?"
Zhao Chuanjia took a step forward and said, "According to His Highness's instructions, the steel-making workshop formerly belonging to the East Palace Military Research Institute prepared fifteen huge iron blocks for the ministers. The ministers transported them to the Leizhou Peninsula, on the top of Leiyun Peak.
I found an excellent location for lightning strikes, and successfully bathed fifteen large iron blocks in the lightning, but - they are magnetic and cannot be retained for a long time, and the magnetism is very messy!"
Zhu Jianji was stunned, "How could this happen?"
Zhao Chuanjia sighed: "I don't know either."
Zhu Jianji was confused. No, according to his common sense, it is indeed possible for iron and steel to produce magnets after being struck by lightning. Fifteen iron blocks should produce one or two permanent magnets at the lowest probability.
Where did the question come from?
Zhu Jianji couldn't sit still. This was a big deal.
Asked: "Are you sure you followed the steps Gu said?"
Zhao Chuanjia and Zhu Bi nodded, "I dare not deceive you."
Zhu Jianji suddenly felt a pain in his head. Without magnets, how to generate electricity? How to make money if there is no way to generate electricity? The most important point is that once the Ming Dynasty builds a city that never sleeps, it will be possible to take the lead in becoming the center of the world in terms of urban prosperity.
This is a national image issue!
What went wrong?
Zhu Jianji fell into deep thought.
The memory racking his brains - about how lightning strikes steel to create a permanent strong magnet, he saw it in a cartoon. After so many years, he only remembered to use copper wire and insulating paint.
There must be a mistake in some operation step!
In fact, natural magnets can also be used.
But Ming Dynasty does not mine natural magnets at all.
Then you have to grasp it with both hands.
Zhu Jianji thought of this and shouted to Dai Yi at the door: "Xuan Hangmin."
Then he said to Lu Chunjing, Zhao Chuanjia and Zhu Bi: "You should go back to your mansion first and rest for a while. Then you can go to Leizhou Peninsula after spring. You must make magnets."
The three of them retreated.
Before Hang Min arrived, Zhu Jianji continued to think, hoping to remember which step caused the problem.
When Hang Min arrived, Zhu Jianji had some thoughts.
It should be because the electric field is not isolated and the magnetic poles are not determined.
Just find the problem!
Try a few more times and you will always succeed one day.
Zhu Jianji excused himself from Hang Min and said, "Is there any mining of magnetite over there at the Ministry of Industry?"
Hang Min shook his head, "No."
Zhu Jianji felt a little helpless, "Where is the magnetite mine in the Ming Dynasty?"
Hang Min, as the Minister of Industry, is familiar with mineral resources across the country. Hearing this, he immediately said: "Daye County, under the jurisdiction of Xingguo Prefecture within the jurisdiction of Huguang, has a large number of magnet mines."
Zhu Jianji thought for a while and asked, "Can the Ministry of Industry mine and process magnetite?"
Hang Min thought for a long time and said, "You can try it."
Zhu Jianji immediately said: "The Ministry of Industry will immediately arrange for people to go to Daye County to inspect, and strive to establish a complete system for magnetite mining and processing within half a year."
Hang Min advised: "Your Majesty, the magnetite mine has very little use, so there is no need to waste manpower and financial resources to mine it."
Zhu Jianji thought it made sense and he couldn't use so much.
Then he changed his words and said: "In this way, the Ministry of Industry should make preparations first. After the spring, Zhao Chuanjia and the others will go to Leizhou again. If the start is unfavorable, the mining of magnetite will be imperative. If the problem is solved, there will be no need to mine.
.”
Hang Min accepted the order.
Zhu Jianji added: "Let the steelmaking factory prepare some copper wires."
Daming can produce copper wire.
In fact, the production of copper wire and iron wire in China started very early. The copper wire used to connect the stone pieces on the Terracotta Warriors and Horses of Qin Shihuang is recorded in "Tiangong Kaiwu", so the Ming Dynasty during this period must have been able to produce copper wire.
Sure enough, Hang Min asked without saying anything, "How much copper wire does your Highness want?"
Zhu Jianji thought for a while, "For copper wires the size of your little finger, prepare about three hundred feet. For copper wires the size of toothpicks, prepare about one thousand feet... Well, after a while, the demand will increase, and we may have to set up a special
copper wire production workshop."
Hang Min took a breath and said, "Your Highness, it's very expensive."
Copper is not cheap.
That's all money!
Moreover, the Ming Dynasty has always been short of copper. Your Highness uses copper to build copper wires. Isn't this a waste of natural resources?
Zhu Jianji hummed, "I know it's very expensive, so you don't have to worry about money. Just calculate how much it costs. I'll ask Lu Chunjing to transfer it from the Royal Electric Power Company's account to the steelmaking plant later."
In the fifteenth century, not only during the Ming Dynasty, but also in the entire world, there were no aluminum products. Zhu Jianji could only use copper wire as the core of the wire. It was expensive, but the profit was high. In the 21st century, all wires also use copper core.
As for the copper shortage in the Ming Dynasty...
After a few years of successful external expansion, what else will my Ming Dynasty lack?
