According to Su Hao's conjecture, without mechanical assistance, it would take several days for the Hao family father and son to grind out the lenses of a pair of telescopes. Who knows, early the next morning, when the whole family hadn't gotten up yet, Su Hao heard someone banging on the door knocker of his house desperately, and shouted excitedly while patting it: "The virtuous nephew of the change, the virtuous nephew of the change, have you ever gotten up?" ”

Khan, is there such a disturbance to people's dreams?

Although Su Hao complained in his heart, he still put on his clothes quickly and ran downstairs to open the door.

Standing outside the door, it was Hao Yizong and Hao Qing father and son, Hao Yizong's hand was holding an object composed of two cylinders, in the entire Ming Dynasty, only Su Hao could recognize it, this is clearly a telescope.

"What, Uncle Hao, the telescope has been made?" Su Hao asked.

"It's done, it's done, you see, nephew, but is this thing?" Hao Yizong handed the telescope in his hand to Su Hao, with an irrepressible smile on his face, and his hands trembled a little.

Su Hao took the telescope and looked at it carefully, and couldn't help but feel shocked. Both barrels of the telescope are made of iron sheets, covered with cloth, and feel very comfortable to hold in your hand. The lenses are wrapped in thin strips of cowhide and then embedded in the barrel, and the seams are very tight, so that there is no light leakage. The two objective lenses and the two eyepieces are polished so smooth that no blemishes can be found with the naked eye.

Su Hao tried to raise the binoculars, put the eyepieces in front of him, and looked into the distance along the alley at the door. The stall selling breakfast at the entrance of the alley was suddenly pulled in front of Su Hao's eyes, and he could even clearly see the mole on the peddler's face.

"What is this, let my brother see it?"

Deng Kui's voice came from behind Su Hao. Deng Kui and Hao Tong maintained their habits in the army, getting up early every morning and practicing martial arts in the back garden. Hearing Hao Yizong's voice calling the door, the two of them came to the front door, and met Su Hao inspecting the newly baked telescope.

Su Hao smiled and handed the telescope to Deng Kui's hand, and Deng Kui took it. Following Su Hao's example, he put the telescope flat in front of his eyes and put his eyes on the eyepiece. Unable to choose a target, he couldn't tell what he was seeing for a while. Su Hao pushed the telescope with his hand and aimed it at the target in the distance. Deng Kui was slightly stunned for a moment. Suddenly he shouted: "God, what an artifact this is!" ”

Hao Tong, who was standing beside him, heard Deng Kui's exclamation, and hurriedly snatched the telescope from Deng Kui's hand and watched it in front of his eyes. As a result, like Deng Kui, he also shouted excitedly. The two GIs took turns trying out the binoculars, looking south and north, and then raising the camera to look at the tall trees in the distance, having a great time.

"Virtuous nephew. What do you want to do, but like this? Hao Yizong asked, Deng Kui and Hao Tong's performance did not surprise him at all, because he was also shocked when he made this telescope just now.

Su Hao nodded and said, "That's right, I thought it would take several days to grind these lenses, but I didn't expect Uncle Hao to grind them so quickly." ”

Hao Yizong said: "Since the virtuous nephew left yesterday morning, my father and son have been grinding these lenses non-stop. At first, I didn't feel the essentials, and I wore out a few pieces. By dinner time. We just polished the four pieces and then made the two tubes, which took a lot of work. ”

Su Hao said: "Uncle Hao and Brother Hao's craftsmanship is really breathtaking. This binocular, not only the lenses are well polished. Even the lens barrel is a boutique, and the little nephew really admires it. ”

Hao Qing put his hands behind his back and said to Su Hao: "Brother Xian, although this telescope is good. But the foolish brother feels that there are still some shortcomings. This telescope can only see fixed places. If you want to look elsewhere, it's a bit vague. ”

Su Hao smiled: "This is not a big problem, I didn't make it clear yesterday." The distance between the two lenses should not be fixed, so that the position of the lens can be adjusted according to the distance of the place to be seen, a process called focusing. ”

Hao Qing smiled slightly, and stretched out the hand behind his back to the front. Only then did Su Hao see that he was holding a slender cylinder three or four feet long in his hand, which was divided into two sections and put together, and the place where the interface seemed to be movable.

"Monoculars!" Su Hao exclaimed, he took the cylinder and looked at it, and sure enough, there was a lens at each end of the cylinder, which was also installed according to the requirements of the objective lens and eyepiece. He put the monocular in front of his eyes, the lens pointed into the distance. At first, the scene in the lens was still a little blurry, but he pulled the lens barrels back and forth, and the things in the distance became clearly recognizable.

It seems that the ancient Chinese craftsmen were really not to be underestimated, they actually thought of the problem of adjusting the focus without a teacher, and solved it in the simplest way.

Su Hao turned the monocular over and looked at it, and found that the objective lens in front of him was one size larger than the binocular, and the magnification was also higher. In this way, the telescope can see farther and at the same time over a wider range.

"Hey, the lens in front of this telescope isn't the glass lens we made at the beginning?" Su Hao asked.

Hao Qing said with some embarrassment: "Last night, after making that binocular, my father and I were pondering the truth of this telescope. Later, I thought that if I could make the lenses bigger, I might be able to see farther. So, we returned a few pieces of worn glass to the furnace again, cast a larger piece of glass, and grinded it into the lens of this telescope. ”

"Didn't you sleep all night?" Su Hao asked, he noticed that the eyes of the Hao family father and son were bloodshot, and they stayed up all night to work, and they were doing this kind of meticulous work of grinding the camera, which should be very tiring.

"Qing'er is young, and it's okay to work all night. The old man is old, and he can't stand it until the fourth watch, so he went to take a nap. Hao Yizong replied.

Su Hao said apologetically: "Oh, blame me, in fact, this matter is not so urgent, how can I be embarrassed to let Uncle Hao and Brother Hao stay up all night to catch up with work." ”

Hao Yizong said: "What is this, when the old man is working in the Miscellaneous Work Bureau, he has it when he doesn't sleep for seven days and seven nights in a row." The telescope invented by the virtuous nephew is really ingenious, and it is never easy to sleep and eat until you finish making such a thing. It is gratifying that the old father and son stayed up all night, and their work was not in vain, and it was not in vain to be able to make such a magical thing. ”

"It's all thanks to the whimsy of the younger brother of the change, otherwise we wouldn't have wanted to do this." Hao Qing added.

Su Hao waved his hand and said, "I just had an idea, and I felt that I could do this, and I really turned this idea into a real thing, thanks to craftsmen like my uncle and eldest brother." If I had to do it myself, I wouldn't have been able to wear a single lens in my life. ”

While everyone was talking, Yang Gendi and Lu Xiuer also finished washing up and walked out. Yang Gendi greeted politely: "Don't stay outside, come into the house and sit, I'll make breakfast for you." ”

Hao Yizong and Hao Qing hurriedly saluted Yang Gendi, Su Hao introduced them to each other, and everyone spent some words on the issue of titles, and finally decided to let Yang Gendi call Hao Yizong the eldest brother, and Hao Yizong called Yang Gendi the younger brother-in-law.

Hao Yizong and Hao Qing had breakfast at Su's house, and Su Hao re-discussed the improvement of the telescope with them, suggesting that they install a gear device on the barrel of the telescope, so that they can use the wheel to adjust the focal length. The father and son of the Hao family fully understood this design as soon as they heard it, so they finished their meal hastily and went back to make other telescopes in a hurry.

Seeing off the Hao family's father and son, Su Hao looked at Deng Kui and Hao Tong who were playing with the telescope with a smile, and asked, "Two, how is this play, can you give an evaluation?" ”

"This thing is so useful that it can add a pair of clairvoyance to the scouts in our army. In front of the two armies, if the commander looks at the enemy with this object, he will definitely be able to strategize and win a decisive victory. Hao Tong did not hesitate to use the best comments to evaluate the telescope in his hand.

"Well, if you think this thing works. Now is it time for us to talk about the price? Su Hao still asked with a smile.

Deng Kui glared and said, "Master Su, just such a thing, how much money are you going to ask our brother?" ”

Su Hao said: "This is not how much money to ask your brothers, but how much to ask Deputy General Deng for money." This is equipment in the army, should it be procured at military expense? ”

"Well, that's what I said." Deng Kui said, "You tell me the price." ”

Su Hao stretched out a hand, spread his five fingers, flipped back and forth, and said, "100 taels and one, how about it?" ”

"You're robbing money!" Deng Kui said loudly, "Our brother saw how you did this thing yesterday, but it's just a few stones to boil, how much is it worth?" These things such as grinding mirrors were all done by Uncle Hao and the eldest brother. They all said they didn't want money, and you actually asked for 100 taels? ”

Su Hao snatched the telescope from Hao Tong's hand, hid it behind him, and said: "Love or not, this telescope is 100 taels a piece, unless you start to grab it, otherwise, take out the silver first." ”

"You ......" Deng Kui and Hao Tong were dumbfounded. If they really want to use force, of course they are not afraid of Su Hao, and they don't even have to be afraid of Su Hao reporting to the official, because their backers are far tougher than those of Fengcheng County. But the problem is, everyone is already so familiar, how can there be a reason to turn their faces and grab things? Besides, Su Hao dared to argue with them like this because Tu Wenhuan admired him very much, Deng Kui and Hao Tong nominally belonged to Tu Wenhuan sent to protect him, how could there be any reason to do it with the protected?
