At night, the cool breeze is blowing.

In the mud room, Cheng Yi thought quietly, he stayed in the 'Glass Research Institute' for a day during the day, and the Qin Dynasty was originally going to send Cheng Yi to Qingfeng Manor for placement, but Cheng Yi felt that the daytime viewing was still unfinished, so he asked to stay in the institute.

"Master, this Qin Xian Ao is terrifying!" the old servant on the side whispered.

Cheng Yi glanced at him strangely and smiled, "What's terrible?"

"Sir, you also know my family business. ”

"Your family has been burning pottery and glass porcelain for generations. Cheng Yi nodded, speaking of Liuli, if before today, if asked who knew best, Cheng Yi would definitely think that it was Cheng Ming beside him.

"This glaze, from ancient times to the present, the color, pattern, and style have always been difficult to fully grasp. Cheng Ming was very emotional, "We can know that some mines can burn green glass, know that some stones can burn yellow glass, and also know which stones are used to burn blue glass, but whether it is green, yellow, or blue, or other colors, it is not pure, and it is a big surprise that a glass product can be more than ninety percent pure color." “

Cheng Yi nodded, why at first glance the glass of the Qin Dynasty was worth a thousand gold, it was because for thousands of years, there were too few pure and transparent glasses, and each one was extremely rare and could not be bought with money.

"Qin Xianao's pure color glass here, like we burn, it takes hundreds of years to get one, its value can be imagined, I also have three pieces of solid color glass products stored at home, this is a family heirloom accumulated over thousands of years, and now it ......" Cheng Ming smiled bitterly.

"Although Qin Xianao's glass comes out, your heirlooms accumulated for thousands of years are not worth a few dollars, but you still keep them, after all, they are also historical witnesses. Cheng Yi said in a deep voice.

"That's all there is to it. Cheng Ming sighed. said: "The craftsmen who burn the glaze have accumulated thousands of years of experience, and the glaze is still the glaze, and we still treat these experiences as a secret in the secret, and the secret is not revealed, and now it is a complete joke when I think about it." ”

"Thousands of years of experience. It's not as good as people playing casually. Cheng Ming's figure was a little lonely, after listening to the Qin Dynasty's narration, and wandering around the glass research institute all day, Cheng Ming now understands that in general, Qin Xianao has been able to burn whatever color of glass he wants, what purity, what pattern, even if some colors can't be made now, but with the progress of others. It won't take many years, but as long as you can imagine the style, he can burn it for you.

Compared with others, the burning glass of his Cheng Ming family is not at the same level at all.

The most exciting thing is that Cheng Ming regarded his family's experience of burning glaze as a treasure who would rather die than reveal it, but Qin Xian is arrogant!

Cheng Ming didn't believe that a smart person like Qin Xianao didn't understand the value of these glasses.

"Huh?" Cheng Yi pushed open the door and saw a young man walking over: "Mr. Yichuan, this place is shabby. It's really sluggish, right. My name is Luo San, and I live next door, if you have any commands, you can call me. ”

Cheng Yi nodded slightly: "Luo San, why should Gongzi Qin bother now?" Because Cheng Yi was unwilling to leave, the master of the Qin Dynasty naturally did not want to go back to Qingfeng Manor directly. So it also stays in the 'Glass Research Institute'.

"Gongzi Qin should be instructing Mr. Qin Ya to do their research!"

"Do research?" Cheng Yi's eyes lit up, and he said, "I wonder if you can take me to see it?"

"Childe ordered, and Mr. Ikawa's requests were all agreed. Luo Sanhan smiled, "Please come with me." "Luo San. Do you know what kind of research Qin Gongzi is doing?" "What kind of mirror is it, Mr. Yichuan will know when he goes to see it." ”...... Soon, three miles away from the Glass Research Institute, secluded by the mountains and rivers, built a large courtyard, Cheng Yi and others arrived at the gate, the Qin Dynasty had already led people to greet them, a little courtesy, after the introduction.

"Qin Gongzi, I heard Luo San say that you are instructing people to do research, what kind of mirror or something, I don't know?"

Everyone walked into the house, and Cheng Yi asked directly.

"Make some glass-related tools, such as microscopes!" Qin Chao said.

"Microscope?" Cheng Yi looked at Qin Chao confused.

Qin Chao smiled: "Wait a minute, you will know, in addition to the microscope, there are also telescopes and ......"

"Telescopes?" Cheng Yi smiled, "Gongzi Qin, don't tell me, you don't have a telescope now? ”

"Mr. Ikawa is right, the previous telescopes are indeed a little lower in magnification, and the distortion of the lenses made of crystal is too large, which is not as good as professional glass lenses. ”

"The crystal is really distorted. Cheng Yi nodded, now the telescopes used in the martial arts world are made of crystal, although everyone has done a very good job, but the distortion rate is still miserable, but it is used to observe celestial phenomena and distant scenes, and the crystal telescope with large distortion is also better than the naked eye.

"Professional glass?" Cheng Yi said, "I think this glass is extremely transparent, transparent, I don't know how much better than crystal, how can it not be used to make lenses?"

"Most of the glass effects do throw off the crystal a few streets. Qin Chao smiled and said, "But if there can be a better one, naturally we have to use a better one, the ordinary glass we made, although it is difficult to find with the naked eye, but there are bubbles inside it, which is used to make lenses, which is not very good, these bubbles will make the light ......" Qin Chao introduced the knowledge of glass, and gradually everyone came to an attic with a bright light.

"That's ......" Cheng Yi glanced at the attic and found that there were long cylindrical objects on the pavilion above the second floor. "It must be a telescope. Cheng Yi pointed to the pavilion.

"Mr. Ikawa guessed right. ”

Cheng Yi's eyes flashed brightly: "Young Master Qin, you ...... There are twenty-five in one pavilion, and there are only a few telescopes in the entire martial arts world, you are really ......"

"Haha. Qin Chao laughed, "I dare to do this because I have glass, these telescopes are all experiments, not finished products that are really taken out and used." ”

"Experiments?"

Cheng Yi was stunned for a moment, and then laughed, "Doing so many telescopes as experiments, it's like Qin Xian arrogantly dares to do this." He dodged, flew into the sky, and landed on the pavilion.

"Uh......" Qin Chao blinked, looked at the attic gate close in front of him, and the stairs inside the door, then smiled, and also flew into the sky and landed on the pavilion.

Cheng Yi put his eyes on a telescope, and after just one glance, his pupils dilated.

"This is the moon?"

Cheng Yi often looks at the moon with his own 33 times telescope, and at this moment, the moon he sees from the mirror can obviously feel several times clearer than what he sees through his own telescope, which feels like a myopic eye, unable to see things in the distance, and suddenly wearing glasses.

"Mr. Ikawa, that one is a semi-defective product, the worst of the fifteen here. A rough voice rang out.

"The worst?"

Cheng Yi's hand trembled, and he turned his head to look at Qin Ya who was speaking, such telescopes are all defective, so wouldn't he have to throw garbage on the one in Cheng Yi's mansion?

"Mr. Yi Chuan can try this one, this one has a multiplier of 36 times, but the glass and modulation are more appropriate, and it can already be made into a finished product. Qin Ya pointed to a telescope that looked similar to Cheng Yi's in front of him.

"Then I'll try. Cheng Yi stepped forward, leaned over his eyes to look over, his breathing was tight, the moon in his line of sight was obviously clearer than just now, Cheng Yi slowly moved the camera to the direction of Jupiter, and soon Cheng Yi's eyes widened again, and Jupiter in his line of sight was also extremely clear.

"Mr. Ikawa, that multiple is too low. Qin Ya hummed.

"Low multiple?" Cheng Yi's face was weird, he put down his binoculars and looked at Qin Ya.

"Mr. Yichuan, this is 50 times, and this is 60 times, this is ......" Qin Ya introduced them one by one, Cheng Yi looked at them one by one, time passed, and Cheng Yi looked more and more interested.

The moon is closest to the earth, and Cheng Yi can know the general appearance with the telescope at home, but the other gold, wood, water, fire and earth, are seen in the fog, although they can see clearly than the naked eye, but the veil of mystery has been shrouded in can't see clearly, and this time, with the help of a higher magnification of the telescope, he can barely see the face of Jupiter.

At this time, Cheng Yi's eyes left a telescope and looked to the right, where cylindrical cylinders were put together on a shelf, and the lens barrel in the middle was extraordinarily thick.

"This one is ......"

This telescope looks extremely strange, it doesn't look like a telescope at all, and there is more than one that doesn't look like a telescope.

"It's called a reflecting telescope. Qin Chao raised his eyebrows.

"Reflexes?"

Cheng Yi was stunned, it was another new term.

"How many times is that?"

"Sir, I'd better take a look first. Qin Chao said with a smile.

Cheng Yi raised his eyebrows: "Well, the old man wants to see how effective this weird-looking 'reflective telescope' is?" stepped forward and was about to put his eyes under the copper mirror. "Mr. Ikawa, this one should be seen from above. Qin Chaolian stepped forward to demonstrate.

"Here?"

Cheng Yi stared, usually the telescopes are mostly cylindrical cylinders, one head up, facing the target, and the other side down, used to watch, but when the Qin Dynasty was demonstrating, his eyes were sticking out next to the **** end like a tree mark on a tree pole.

"Isn't it the refraction of light?" Cheng Yi thought for a while, and the 'optics' written by the Qin Dynasty flashed in his mind, and Lian said.

The same can be said. Qin Chao nodded slightly and moved out of the way. Cheng Yilian took a step forward and aimed his gaze at the place where the Qin Dynasty demonstrated, and his eyes suddenly lit up, this time the moon does not have much advantage in size compared with other telescopes, but the image is ...... Cheng Yilian found Jupiter again, and this time the image in his eyes was even more shocking.

"How so?"

Cheng Yi looked at the Qin Dynasty: "This is different, different from what I see in others." ”

"Mr. Yi Chuan still remembers what I wrote about 'optics', if the focal ratio of a normal telescope is relatively small, there will be a serious optical spherical aberration, that is, image distortion, and the reason for this is ......" Qin Chaolian explained the principle of the reflecting telescope invented by Newton, and soon -

That's pretty much it. Qin Chao paused to explain.

Cheng Yi nodded slightly: "This reflecting telescope is good, I thought there would be something new, but I didn't expect the principle to be your optical, the old man has a long insight, by the way, what kind of microscope you said earlier is ......"

"The microscope is in the room, and Mr. Ikawa will come with me. (To be continued.) )
