"The son knocks to see his father!" Even though he entered the hall to salute, he didn't put down the binoculars in his hand.

Emperor Yuan An saw at a glance that he was holding something in his hand, and couldn't help asking, "What are you bringing here?" ”

Yu Zuo handed over the telescope to Zheng Ze, and Zheng Ze sent it to Emperor Yuan'an's desk, and then said excitedly: "Father, this is a telescope, it can help the scouts in the army to observe the enemy's movements outside the field of vision from a long distance, and it can also help the generals and commanders of the army to see any changes on the battlefield and understand the enemy at a glance in intelligence!" ”

Such a big breath?! Yu Zuo's description, Emperor Yuan'an was shocked, he picked up the thing in front of him, flipped through it in his hand, and didn't see where this thing looked like a magic weapon?

"Father, you have to keep it in your eyes and look into the distance." Yu Zuo hurriedly explained.

With the assistance of his son, Emperor Yuan An also quickly learned how to use the telescope, and after confirming its efficacy, Emperor Yuan An was stunned for a moment: "If there was such a wonderful thing in the first place......

He shook his head, shook off some of the thrilling battlefield memories in his mind, and looked up at his son: "Where did the things come from?" Could it be that your companion was tinkering with it again? ”

Emperor Yuan An even remembered that Fu Yuchen of the Fu family was a natural Mo family giant with a whimsical mind? Yu Zuo couldn't help but be stunned: "Father Emperor Shengming!" ”

Emperor Yuan An actually said it casually, but he didn't mean to say it, and immediately smiled "haha", and praised: "The Fu family kid really has a few different skills, but today only you came, he didn't follow you, it seems that the real purpose of this thing I am afraid he has not realized it, but you saw it first!" ”

Yu Zuo said with a smile: "Father Emperor Mingjian, Yuchen made this telescope for me, just so that I can see the young birds in the eagle's nest from afar in the poultry shop. ”

Emperor Yuan An laughed when he heard this, and looked at Zheng Ze: "This kid of the Fu family!" ”

Zheng Ze smiled with a slight smile: "The heart of a child, can it be pure?" ”

Emperor Yuan An nodded again and again, and sure enough, it had to be Zheng Ze, and he said what he meant.

"The essence of this telescope is all in this extraordinarily transparent crystal plate." Emperor Yuan An also saw through the core components of the telescope at a glance, which were the four incomparably transparent glass pieces inlaid on it, and as for the wooden sleeve wrapped on the outside, although the design was also quite ingenious, it was very easy to imitate, and it could also be replaced by other materials.

"I've never seen such a transparent crystal or glass ......," Emperor Yuan An muttered, looked at Yu Zuo again and muttered: "You go back and ask Fu Yuchen in private, how did he get this transparent crystal piece?" Ask him again, can the source of the material and the secret recipe for the manufacture of this crystal piece be sold to the royal family? ”

Yu Zuo understood the emperor's consideration in seconds: "Yes!" Erchen knows! ”

Emperor Yuan An nodded: "This is a sharp weapon in the army, and its manufacturing method cannot be leaked, nor can it be held in private hands, it must be nationalized, you represent the royal family, explain this carefully to the child, and the conditions are as he mentioned, let him discuss with the Marquis of Jingbei to come up with a result, within a reasonable range, try to meet their requirements, and do not go up and suppress people." ”

"Erchen understands!" Yu Zuo solemnly agreed.

Emperor Yuan An discussed with his son some bottom-line conditions in exchange for the other party's unique manufacturing secret recipe, and then let Yu Zuo go back, and finally encouraged: "Do things well!" After the Holy Birthday Day, I will be rewarded. ”

On the other end, Fu Xuechen didn't know that he had stepped on a thunder again, and he had seen enough of the little milk cat, so he left the cattery happily, and he didn't see Yu Zuo when he came out, and he didn't care, in the past, when she came to Zhen Beast Fang, she looked at the cat, and Yu Zuo went to see his Hai Dongqing, and when she left, she might not wait for her to go with her.

That night, he went to Qingtong Courtyard again, and Fu Xuechen briefly finished talking about today's lackluster experience, and made fun of Fu Yuchen: "I heard Furong say that you got the telescope this morning, and you took it to the attic window for almost the whole day, how about it?" See anything interesting? ”

Fu Yuchen sighed: "There are a few little girls in the courtyard of the partition wall who are kicking shuttlecocks, playing crazy all morning, and they are all punished, on the side of the east courtyard, my mother has seen several people in charge, busy with the account of the month, and over there in the west chamber, Aunt Wu took a big basket of needlework and ran to force our sister to learn tailoring, pitiful!" ”

Shaking his head, Fu Yuchen played with the telescope in his hand, and did not continue to think about it, but gave an evaluation: "It's a good thing, it can greatly expand people's horizons, but it's a pity that it's used in the house, and all you can see is the daily life of chickens and dogs around you, and it should be used in the open field in the wild, as a clairvoyant, to observe the movement in the distance." ”

Fu Xuechen "hummed" lightly: "Huh! I have to warn you, the backyard is full of women, don't learn to be lewd men, relying on this thing to be able to see far away, no one is defenseless, so you will go to watch other people's privacy at will! ”

"Don't look at the gentleman's indecency, don't deceive the dark room, I'm not so lacking in morality." Fu Yuchen sneered, let go of the telescope in his hand, picked up the Journey to the West script again, and said casually: "You also gave a pair to the six princes." ”

"That's right! What's wrong? Fu Xuechen didn't understand why he was emphasizing this sentence.

Fu Yuchen gloated: "Let's wait!" You're in trouble again! I heard that you have only made a few pairs of these telescopes, and I tell you, this number is 108,000 miles short of the royal demand, and they will definitely try to make it in your hand, so you might as well go back and think about it, what do you want to exchange for the recipe! ”

Fu Xuechen thought at first that he heard that he had also given a pair to the six princes, and he wanted to sour a few words, but when he heard such words, he couldn't help but be stunned: "Why don't I have a telescope in the Darong Empire?" ”

Monoculars? Fu Yuchen was surprised: "Where did you hear that there are such strange things in our empire?" ”

"...... imported from the West" Fu Xuechen suddenly stood up: It's broken! Could it be that in this time and space, there are no foreign merchants and foreign priests who have crossed the ocean from the West? Obviously, it looks like the Darong Empire is very similar to the Ming Dynasty in the previous life?!

If the West had not yet opened ocean voyages, then there would not have been any Western captains who brought their more common monoculars there, and there would not have been so many pairs of binoculars flowing into the palace, so suddenly taking out the binoculars by themselves could not be regarded as a small improvement from monocular to binocular, but a big step from scratch!

"I won't tell you, I have to go and tell my father!" Fu Xuechen couldn't care about chatting with Fu Yuchen anymore, hurriedly dropped a sentence, turned around and went out, and went straight to the main courtyard.

Fu Yuchen looked at her distant back, and narrowed his eyes slightly: "There are already monoculars in the West?" In the past, the Korean sea trade was repeatedly banned, but I have never heard of such a thing in the West......"

"Fleur!" He shouted.

The big girl Furong was outside, and hurriedly came in when she heard the sound: "Young master? ”

"You go to the master's study tomorrow, as well as my original small study, and find me all the essays and travelogues about the countries of the Western Regions, etc., regardless of what type of books and materials."

Fu Yuchen simply handed over the matter to Furong, he wanted to see, which small Western country actually took the first step to create a sharp weapon that can look far?
