After Liu Pei learned that the Ryukyus had been settled, he calmed down and continued to transport the victims. After a period of time, everyone was already familiar with this kind of work, and Liu Pei finally breathed a sigh of relief and pulled out. The first thing he did when he came out was to inspect the Academy of Sciences. The Academy of Sciences has sent him several letters urging him, but Liu Pei has never had time to go. It wasn't until everything was on track that time passed.

When Liu Pei led people to the Academy of Sciences, Bao Dezhi personally greeted him at the door. When Bao Dezhi saw Liu Pei dismounting, he greeted him and said, "Dashuai, we haven't seen each other for a long time!" ”

Liu Pei smiled and said, "Yes! During this time, it was both war and disaster relief, and it was too busy! I really didn't have time to come. But it looks like you're looking good! ”

The Academy of Sciences is Liu Pei's top priority! Liu Pei did not withhold any supplies from the Academy of Sciences when food was most scarce. And he also gave a death order, everything reported by the Academy of Sciences must be solved as soon as possible. So these people live quite nourishingly in the Academy of Sciences.

After Bao Dezhi snorted, he led Liu Pei inside. Liu Pei asked, "You have sent several letters to urge me, what is the matter?" ”

Bao Dezhi said: "Isn't this a result? Then you have to ask the marshal to take a look. ”

Liu Pei was refreshed when he heard this! Said: "Good! What's going on? ”

Bao Dezhi said: "The handsome man will know if he goes in and has a look." ”

The two of them came to a large house while talking. The house looks like a large room like a conference room. But there are no tables or chairs inside. There is only one row of shelves. There were a few things on the shelf, and I couldn't see them from afar.

Liu Pei took a closer look, and it turned out to be a sample covered with a glass cover. Liu Pei recognized a mirror at a glance. Liu Peihaha smiled and said, "It turns out that you made a mirror, okay!" Good! Good! That's a lot of money! ”

Then Liu Pei pointed to a glass cover next to him and said, "Why is there nothing in this cover?" ”

Bao Dezhi tapped his fingers on the glass cover and said, "Isn't this just something?" ”

Liu Pei was stunned for a moment, then laughed and said, "Glass! It turns out that this glass cover represents a glass product! What a great idea! 【】”

Bao Dezhi then explained: "Glass and mirrors have been out for a long time, and now they are waiting for you to make a decision, is it mass production? It's just that mirrors are a hassle to make now! The latter coating can now only be made using the dissolution method. So the scrap rate is high. In addition, long-term exposure to mercury vapor is life-threatening. ”

Liu Pei nodded indifferently and said, "It's okay!" The scrap rate is high, and the price

Ge is a little more expensive. As for the staff, I have death row inmates there! ”

In ancient times, when there were no mirrors, people used mirrors made of silver or copper-tin alloys. But the metal mirror quickly darkens in the air. Then it finally occurred to someone that the metal side could be covered with glass to prevent it from coming into contact with the air – just like we now put our photographs in glass frames, and this is where we have glass mirrors.

So people found a way to stick the metal behind the glass. So someone invented a solution: put a piece of tin foil on a piece of glass and pour mercury on it. Mercury dissolves tin. The liquid thus made has one property - it adheres firmly to the glass floor. When the time is up, tilt the glass to its side a little to let the excess mercury run away. In this way, it takes a whole month to coat the entire piece of glass with an even layer of metal. Moreover, mercury is poisonous, and it will be poisoned if you come into contact with it too much.

Liu Pei looked at the glass covers in the back, which contained soap, soap and perfume. Liu Pei was even happier when he saw these things! said: "These things have also been made!" That's our current source of money! I always think about how to solve the problem of the source of goods in the future, but I didn't expect you to make things! Well done! ”

He was happy to see Liu Pei, but Bao Dezhi frowned and said, "Handsome, but these things are not easy to do." Because it takes a lot of food and oil to make these things. ”

Bao Dezhi is right when he says that perfume requires a lot of alcohol. But nowadays alcohol can only be obtained by brewing, and brewing requires a lot of food! As for the production of soap and soap, a large amount of oil is required. And at present, these two things are very lacking in the entire Ming Dynasty. It's okay to say that alcohol can always be extracted with more wine. But no one is willing to use grease on soap and soap. Because that's the food that's important for people.

Now the common people of the Ming Dynasty do not eat meat like modern people, and they don't even eat meat. And now it is difficult for the people of the Ming Dynasty to eat meat. As for those who can eat meat, they all choose fat and eat it. It's good to be as fat as you are!

In the face of this kind of thing, Liu Pei can't help it. He also didn't want the grease to be wasted on making the best soap. But then Liu Pei slapped him in a row. said: "There is a way! ”

Bao Dezhi also knows the actual situation of Daming at present, so he is also hesitant about this matter. Listening to Liu Pei say that there is a way to solve it, it is also a shock to the spirit! Directly asked, "Is there any way?" ”

Liu Pei raised his eyebrows and said, "Whaling!" ”

Bao Dezhi also slapped his face and said, "That's right! How I didn't think of whaling! ”

In fact, whaling can be traced back to prehistoric times, when people in the Arctic used stone tools to hunt whales.

The Basque Country was one of the first Europeans to engage in commercial whaling, braving the wind and waves to travel long distances to the coast of Newfoundland and Iceland. Such voyages across the Atlantic began as early as 1372.

In the 17th century, both the Dutch and the English formed large whaling fleets. In the 18th century, a refining furnace was installed on whaling vessels, allowing whalers to refine valuable whale fat into oil at sea and store it in barrels without having to drag the whales back to shore for processing. With this processing capacity, whaling vessels are often able to stay at sea for long periods of time.

After the whale is caught, the whale's fat can be made into whale oil. And candles made with whale oil are the best. There is almost no smoke and the lights are bright. At the same time, these whale oils can be used as soaps, important raw materials for soaps.

Not only that, but whale meat is also edible! Although I heard that it was fishy, I believe that Chinese chefs will find a way to get rid of the fishy smell. And for people at this time, it is a blessing to be able to eat meat, who will not eat it because it smells a little fishy!

In the 18th century, there were nearly 1,000 whaling ships in the world. A series of industries developed around whaling. Whaling was very well paid at that time, so women often dressed up as men to work on whaling ships.

And best of all, whaling is an industry that requires courage and skill. And Liu Peizheng needs this industry to hone his rookie sailors. All the novices will work on the whaling ship. As long as they stay on a whaling ship for a year and a half, they will make the best sailors. When the fleet needs to recruit people, these sailors can go directly to the fleet to serve.

At this time, the whaling industry in Europe was already very developed, although it was not yet at its peak, but there were many whales caught every year. As for whether Liu Pei's participation will affect the development of the whaling industry, and even put whales under threat of extinction. These Liu Pei don't care at all! He just wanted to develop the whaling industry as soon as possible, so that he could provide himself with raw materials, and at the same time, he could also get more people employed and train more sailors.

Not to mention anything else, just a whale oil candle is enough for those gentry to willingly take out the money, and after the two of them briefly discussed the problems and details of whaling, Liu Pei said: "Mr. Bao called me here, won't he just let me see these things, right?" ”

Bao Dezhi said: "Of course it's more than that! However, there is no model of those things yet, and if you want to see it, you have to see it on the spot. ”

Liu Pei said: "No problem, let's go now!" ”

After speaking, Liu Pei looked around the empty room and said, "I hope you can fill the whole room with models." ”

Bao Dezhi smiled and said, "Sure!" Maybe I can't see it, but the big guy can definitely see it! ”
