According to Su Hao's guess, without mechanical assistance, the Hao family and his son had to polish out the lenses of a pair of telescopes, which took a few minutes. Unexpectedly, the second morning, when the whole family had not yet got up, Su Hao heard Youru desperately slap his door knocker, and shouted excitedly while slapping: "Get it for a good nephew, have you ever gotten up?"

Khan, is there anyone who disturbs the dream like this?

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 was Hao Yizong and Hao Qing and his son. Hao Yizong was holding an object composed of two cylinders in his hand. In the entire Ming Dynasty, only Su Hao could recognize it. This was clearly a telescope.

"Why, Uncle Hao, the telescope is made?" Su Hao asked.

"It's done, it's done, nephew, look, but is this thing?" Hao Yizong handed the telescope in his hand to Su Hao's hand. His face was filled with an uncontrollable smile, and his hands were trembling.

Su Hao took the telescope and looked at it carefully, and couldn't help but feel shocked. Both tubes of the telescope were rolled out of iron, and they were covered with cloth on the outside. It felt very comfortable to hold in the hands. The lenses were wrapped in thin strips of cowhide and then embedded on the tube. The seams were very tight and there was no light leakage. The two objective lenses and the two eyepieces were polished very smoothly and neatly. When you look at them with the naked eye, you could not find any flaws.

Su Hao tried to raise the telescope, put the eyepiece 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, and he could even clearly see the wrinkle on the vendor's face.

"What's this? Let my brother see?"

Deng Kui's voice came from behind Su Hao. Deng Kui and Hao Tong's second in the army maintained their habits. Meiyao got up very early in the morning and practiced martial arts in the back garden. Hearing Hao Yizong calling, he came to the front door as soon as he entered the second in the night and met Su Hao checking the newly released telescope.

Su Hao smiled and handed the telescope to Deng Kui's hand. Deng Kui took it, imitated Su Hao's appearance, put the telescope flat in front of him, and put his eyes on the eyepiece. Since he could not choose a target, he could not tell what he saw for a while. Su Hao pushed the telescope with his hand and pointed it at the target in the distance. Deng Kui was stunned for a moment, and suddenly shouted: "Lao Yao, what a magical tool this is!"

Hao Tong, who was standing beside him, heard Deng Kui's exclamation, quickly grabbed the telescope from Deng Kui and also came to see it in front of him. As a result, just like Deng Kui, he shouted with excitement. The two soldiers took turns to try the telescope, looked at the south and the north, and then raised the camera to look at the tall trees in the distance, having a lot of fun.

"My nephew, what you want to make, but that's how?" Hao Yizong asked. Deng Kui and Hao Tong's performance did not surprise him at all, because he was so shocked when he just made this telescope.

Su Hao nodded and said, "That's right. I thought these lenses would take several shots to be worn, but I didn't expect Uncle Hao to be worn so quickly."

Hao Yizong said: "Since my nephew left yesterday morning, my father and son have been grinding these lenses without stopping when they entered the second time. At first, they didn't touch the key points and even ground a few pieces. It was only at dinner that we ground these four pieces, and then made these two lens barrels, which took a lot of time."

Su Hao said: "The skills of Uncle Hao and Brother Hao are really amazing. Not only is the lens well polished, but the lens barrel is also good. My nephew really admires it."

Hao Qing put his hands behind his back and said to Su Hao: "Brother, although this telescope is good, Brother Yu feels that there are still some shortcomings. This telescope can only see fixed places. If you want to see other places, it will be a little blurred."

Su Hao smiled and said, "This is not a big problem. I didn't explain it clearly yesterday. The distance between the front and rear 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. This process is called focusing."

Hao Qing smiled slightly and reached out his hand behind him to the front. Only then did Su Hao see that he was holding a three or four-foot-long slender cylinder in his hand. The cylinder was divided into two pieces and the interface seemed to be able to move.

"Monoculars!" Su Hao said in surprise. He took the cylinder and saw that there were indeed lenses installed at both ends of the cylinder, which were also installed in accordance with the requirements of the objective lens and the eyepiece. He put the monoculars in front of him, and the lens was facing the distance. At first, the scenery in the lens was still a little blurred, but he pulled the barrel that was wrapped around him back and forth, and the things in the distance became clear and identifiable.

It seems that ancient Chinese craftsmen should not be underestimated. They actually thought of the problem of adjusting the focal length without any instruction and solved it in the simplest way.

Su Hao turned the monocular telescope over and looked at it. The objective lens in front was larger than the binocular, and the magnification was higher. In this way, the telescope could see further and the range of the telescope could be seen wider at the same time.

"Hey, the lens in front of this telescope is not the glass piece we made at the beginning, right?" Su Hao asked.

Hao Qing said embarrassedly: "Last night, after making the binocular telescope, my father and I were thinking about the principles of this telescope. Later, we thought that if we could make the lens bigger, we might be able to see further. So we re-cooked a few pieces of broken glass sheets and refined them once, cast a larger piece of glass sheets, and ground them into the lens of this telescope."

"Then aren't you sleeping all night?" Su Hao asked. Only then did he notice that the eyes of the father and son of the Hao family were covered with blood. They stayed up all night and worked hard, and they were also a meticulous job of polishing the camera. They should be very tired.

"Qing'er is young, and it's okay for a thousand nights. I'm old and can't stand it until the fourth day of the year. I'd go and take a nap for a while." Hao Yizong replied.

Su Hao said apologetically: "Oh, I blame me. Actually, this matter is not so urgent. Why do you have the nerve to let Uncle Hao and Brother Hao stay up late to work?"

Hao Yizong said: "What's this? I've been doing things in a mixed game, and I've been sleeping for seven consecutive nights. This telescope by my nephew Ming is really a trick. I never finish doing such things and can't sleep or eat. What makes me feel relieved is that my father and son have not been in vain for the rest of the night. It's not in vain to be able to create such a magical thing, and it's not in vain to do this life."

"This is thanks to Brother Gaizhi's wonderful ideas, otherwise we would not have thought of doing this." Hao Qing added.

Su Hao waved his hand and said, "I just had an idea and felt that I could do this and really turn this idea into a real thing, thanks to a skilled craftsman like my uncle and elder brother. If I had to do it myself, I would probably never be able to polish a lens in my life."

While the crowd was talking, Yang Gendi and 6 Xiu'er also finished washing and walked out. Yang Gendi greeted politely: "Don't stay outside, everyone, come and sit in the house, I'll make breakfast for you now."

Hao Yizong and Hao Qing hurriedly saluted Yang Gendi. Su Hao introduced them to each other. Everyone tried to talk about the question of the name. Finally, they decided to ask Yang Gendi to call Hao Yizong the eldest brother and Hao Yizong the younger sister-in-law. After the appointment, they should treat it as relatives and often walk around each other.

Hao Yizong and Hao Qinger entered the Su family for breakfast. Su Hao discussed the improvement of the telescope with them again and suggested that they install a gear device on the telescope barrel so that the rotor can be used to adjust the focal length. The father and son of the Hao family fully understood this design, so they finished the meal in a hurry and went back to make other telescopes in a hurry.

Saying 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 game? Can you give me an evaluation?"

"This object is really useful, which makes our army's scouts have a pair of cliffs. If the commander in front of the two armies uses this object to observe the enemy, he will definitely be able to plan and win the victory for thousands of miles." Hao Tong used the best comments to evaluate the telescope in his hand.

"Well, you think this thing is useful. Now should we talk about the price?" Su Hao asked with a smile.

Deng Kui stared at the eyes and said, "Master Su, it's just such a thing. How much do you plan to ask our brothers for?"

Su Hao said: "This is not how much money you brothers want, but how much money you want from Vice General Deng. This is the equipment in the army, and military expenses should be used to purchase it, right?"

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

Su Hao stretched out one hand, spread his five fingers, flipped back and forth, and said, "How about 1oo two pieces?"

"You are robbing money!" Deng Kui said loudly, "My brothers yesterday saw how you made this thing. It was just a few stones that would be worth a few cents? Mirroring a mirror was done by Uncle Hao and his elder brother. They all said they didn't have any money, so you would have to pay 100 ounces?"

Su Hao snatched the telescope from Hao Tong's hand, hid it behind him, and said, "Do you want it? This telescope is 1oo 2. Unless you take action to grab it, you will pay the money first."

"You..." Deng Kui and Hao Tong were both dumbfounded. If they really wanted to use military force, of course they were not afraid of Su Hao, and they didn't even have to be afraid of Su Hao going to report to the official position, because their backing was much harder than Fengcheng County Government. But the problem is that everyone is already so familiar with each other, how can they turn against each other? Besides, Su Hao dared to challenge them like this because Tu Wenhuan admired him very much. Deng Kui and Hao Tong were nominally sent by Tu Wenhuan to protect him, so how could there be a reason to fight with the protected person?
