The prince does not fight for the heir

Chapter 70

"What is this?" Fu Xuechen asked in surprise.

""Western Regions" and "Maritime Experience Records" were all found in my father's study." Fu Yuchen reported the title of the book, and said with some admiration: "You once told me that you should read more Miscellaneous books, now it seems that you are right! Miscellaneous books contain a lot of knowledge that is not found in the Four Books and Five Classics, no wonder you know so many things."

Because Fu Yuchen had already spread out the pages of the book in advance, Fu Xuechen could easily see the relevant paragraphs of text that Fu Yuchen pointed to her in the two books, which shocked her at once.

The author of "The Western Regions" is a foreign businessman who is proficient in the official Chinese language. His ancestral home is Navarre. He fled all the way to northern India because Navarre was annexed by the Commonwealth of the Western Regions (the predecessor of the Spanish Empire). He started his business of selling spices with Huaxia.

This foreign businessman likes to write travel notes, and he recorded in detail the ups and downs of his life, as well as the customs of the places he visited.

In one passage, he wrote that a Dutch glasses merchant created a new type of glasses that could see distant scenery clearly. The superimposition of two mirrors can help people sitting in theater seats far from the stage to see the performance on the stage clearly.

The author of the book felt that the glasses business could be done, so he contacted the Dutch businessman to discuss cooperation, but unfortunately he was rejected because of the high cost of new glasses and his lack of funds.

The author of "Maritime Experience Records" is a native of Huaxia, a private captain of Ningzhou maritime merchants. This kind of experience also includes the thrilling experience of imperial merchant ships encountering pirates and fighting with pirates, winning by luck.

The captain is very envious of a kind of Western pirates that appeared in the South Seas. They have red hair and green eyes, and their appearance is as ugly as ghosts, but they have a tool for long-distance observation, a metal monocular, one big and the other small.

With the help of such a tool, they can judge the passing of the merchant ship and whether their power can eat the merchant ship from an extremely long distance.

Last time, if there were no ships from the Darong Empire passing by during the battle and drawing their swords to help, they would have been killed. It was really, very lucky to be able to escape the pirates' attack.

The captain heard the name of the tool from other merchants in the Western Regions. It was called a monocular. It came from the Spanish Empire and was very rare. He wanted to own such a tool, but unfortunately he didn't know where to get it.

Fu Xuechen was a little dazed looking at the records in the book. She didn't even know that there were still such books in her study, and that the monocular had indeed appeared in the Spanish Empire. Appeared, it seems that the age of great navigation over there has already begun.

What makes people feel emotional is that, unlike the Ming and Qing Dynasties in the previous life, the Darong Empire in this time and space cannot control the sea. On the contrary, it is somewhat similar to the practice of the Song Dynasty in the previous life. The empire has a rather supportive attitude towards maritime trade, because Darong The commercial tax of the empire is quite heavy, and the national treasury can collect huge commercial tax from the maritime merchants through the Shibo Department every year.

While Fu Yuchen was admiring, he still couldn't figure it out: "That's all the relevant text I can find, how did you make binoculars based on such a little information? Or, do you have other things? Miscellaneous books, more detailed records?"

It is naturally difficult to deduce the manufacturing principle of the telescope from such a few written records, but Fu Xuechen is different. She first built the thing, and then deduced the reason from the result, which became extremely easy.

So Fu Yuchen's question was easy to answer, Fu Xuechen smiled and said: "No, I don't have any other relevant information. It's a coincidence to say that I just saw a sentence mentioned in the written record, saying that it can see far away. The new glasses use the method of superimposing two mirrors..."

"Then our Darong Empire also has a magnifying glass that can magnify text! I tried to stack two magnifying glasses together to observe the distant scenery, and ended up tossing out the telescope like this."

The magnifying glass is an item that has been passed down for thousands of years in China. Although it is not popular, it is not a very rare item among the upper class. Old and dizzy scholars like to use a magnifying glass to assist in reading words, but this kind of The magnifying glass is made of crystal, not glass.

And Fu Xuechen's new telescope uses the principle of the Kepler telescope, which can first obtain an inverted virtual image and then an upright real image with a double-convex lens.

Junior high school students who have studied physics in later generations will know the principles of this thing, and they can DIY it by themselves if they have tools at hand. Just remember the calculation formula. It is not difficult, but it is very common knowledge for later generations of science students. In an era when science is almost deserted Looking at it, it looks amazing.

While Fu Xuechen was answering Fu Yuchen's question, she was secretly happy. She was worried that the matter of making a telescope by herself would be difficult for others to get to the bottom of it!The books and materials that Fu Yuchen found just made up for her lack. In this way, there are traces to follow in the manufacture of her telescope, and it did not come out of thin air for no reason.

"You are extraordinarily dedicated to the sixth prince. It's not worth giving him a small gift, but you dare to give him any idea." Fu Yuchen suddenly said this again.

Fu Xuechen curled her lips and said: "I'm not planning ahead! We will exchange identities sooner or later. It's okay for others, including the emperor, to keep a distance on purpose, so as not to be discovered in the future that we have exchanged identities. But six The prince is different, we may not be able to deceive him in the past, only by trying to please him, can we get his help in the future, and cooperate with us to completely ignore this matter."

At the beginning Xie Shi and Jingbei Hou asked the two brothers and sisters to exchange identities for three months, and they only thought about not leaving any grounds. As long as there is no evidence and they are not caught by others, especially if they are not noticed by the emperor, then even if others are suspicious, they will not be able to. Sue the Fu family for a crime of deceiving the emperor.

Fu Xuechen thought more about it. Although the two brothers and sisters have similar facial features, and because they are still young, there is almost no difference in height, shortness, fatness, and thinness. With the help of the almost disguise-like imitation makeup method brought by her from later generations, they can basically do The appearance is exactly the same, but the personality and temperament are still different after all. People who are not familiar with them can't tell the difference, but the sixth prince who often stays together can probably perceive the difference between the two.

When the two change their identities back to each other, it is one thing for the sixth prince to find no evidence that the two have switched identities, but it is another thing to know the fact that the two have switched identities. If he doesn't like something, it's better to try to gain his love and trust in these three months, in exchange for his silence in the future.
