Shangguan Rui, as the host, was holding a wine cup and was brewing a toast, when he suddenly heard this, the happy smile that had begun to bloom on his face immediately turned into a bitter smile. He was stunned, swallowed his saliva, and said, "...... Don't drink liquor if you reach that point. The body is important......" glanced at Chen Pu and Tian Xiu in a blink of an eye. Teaching two women to drink liquor doesn't seem to be the same thing! He paused, turned back and ordered, "No more liquor!" Exchange the Hundred Flowers Jade Brew! ”

Shang Cheng also felt that he was really a bit of a bad scenery. Besides, what is made from a hundred flowers is not considered wine, and it is more like vinegar when it is sour. Did he really find something to do and go to the restaurant to invite guests to drink vinegar? Seeing that the maid was about to take away the Tao Weng with the liquor, he waved his hand and said, "Count! I'll drink some too. If you think about it, you shouldn't be able to drink three or five cups. With that, he reached out and took the winemaker.

Shangguan Rui immediately said, "Zida, forget it." The body is the tightest. Autumn and winter are cloudy and uncertain, and the most important thing is to beware of the recurrence. You need to be aware of this eye disease. Actually, I can't drink alcohol during this time. It was because you said that you wanted to invite wine and food, that I gave up my life to accompany the gentleman. As he spoke, he rubbed his left upper arm and shoulder with his right hand, grinning his teeth and making some painful expressions. That year, there was a rebellion in Bozhou, and when he was guarding Bozhou City, he was poked with an iron spear under the city wall. At that time, the war was urgent, and I didn't pay much attention to it, and then it fell to the roots. Nowadays, the seasons change between spring and summer and autumn and winter every year, and if you are not careful, you will have an attack. He asked Shang Cheng and the liquor in front of him to be withdrawn, and replaced with Huang Chengcheng's Baihua Jade Brew, "Let's drink this wine today." Eat and drink well, let's sit upstairs and listen to the big songs and enjoy the songs and dances. My family and I mentioned that there are still several commendable characters in the capital in this restaurant, whether it is a big song or a singing book, or a dance or a sword, it is not inferior to other families. If you are not satisfied, if there is anything else you particularly like, no problem, I will send someone to invite you immediately! In a word, when you come to this Linyuan Pavilion, you should go home, don't be restrained! He turned his head and said to Chen Pu and Tian Xiu, "General Chen, Lord Tian, what I said was not only to Uncle Ying, but also to the two of you. In a word, even if you can't go home without getting drunk, you have to take advantage of it! Then he said to the Kabuki at the table, "Be sure to greet a few distinguished guests." Well, it's easy to say anything. If it's not good, I won't forgive. ”

He spoke enthusiastically, and the flamboyant Kabuki tried hard to liven up the atmosphere at the dinner table, but unfortunately, because of Shang Cheng's untimely taboo of alcohol and meat, the scene could no longer be hot. What's more, the four people at this table have their own backgrounds, and each has their own experiences and experiences, not to mention setting off the atmosphere and mobilizing emotions, it is not easy to find a topic of common concern. In particular, Shang Cheng and Shangguan Rui still belong to their respective factions in the army, although it cannot be said that they are clearly distinguished, but after all, there is a barrier, and it is difficult to really get close. Tian Xiu is a seventh-grade minor civil official, and she is still a woman, so of course Shangguan Rui can't surrender his identity to accompany her. He had no choice but to talk to Chen Pu without a word, and occasionally persuade others to drink and hand over a few words. As a result, after eating this meal, he didn't eat a few bites of food, but he was sweating hotly, and he didn't drink a few glasses of wine, but he was already a little drunk.

Everyone didn't drink much, so the meal was eaten quickly. Seeing that it was still early, there was not even a little gray and dark outside the window lattice covered with green gauze, and I asked someone for the next hour, but it was not even a moment before the time of Shen was over.

Shangguan Rui is good at saying that he is not allowed to leave. While asking people to serve tea, they asked people to quickly remove the large table and chairs and drums and stools to make room for singing and dancing.

At this time, even Chen Pu could see that Shangguan Rui had something to say to Shang Cheng. She wanted to pull Tian Xiu to go first, but Shangguan Rui didn't agree, so she had to sit at one end of the case with Tian Xiu, leaving a place for Shangguan Rui to speak.

But Shangguan Rui was not in a hurry to get down to business, he just sat with Shang Cheng and listened to the songs and dances, and praised the mellow singing of this kabuki for a while, and praised the fact that the maiko figure was in place. Shang Chengcheng followed the praise of "good", "good", and "quite skilled". He still can't understand the so-called "Tang Yin" of singing books and big books, and he can't distinguish the high and low sword dances and pipa dances of several maikos.

When Hu Wu was about to finish, he didn't know what Chen Pu said, Tian Xiu exclaimed "ahhhhhh The maid nodded and went out, and without much effort, brought back a briefcase.

Tian Xiu took out a few copper tubes and a box of glass lenses from the briefcase, placed them on several cases, looked at Shang Cheng through Chen Pu and said, "Uncle Ying, you can help me point out, what should this celestial observatory do?" ”

Shang Cheng put down the teacup in his hand, picked up a copper tube and looked at it, opened the box and picked out two lenses to look at, and asked casually, "It's very exquisite." You haven't figured it out yet? ”

"Yes. We've been busy with the people from the Taishi Bureau for two or three months, and we still can't find a clue. ”

Shang Cheng replied and nodded. If you don't find a clue, keep looking; The path of science is inherently tortuous; This is normal. He turned his face to Shangguan Rui and spoke: "...... By the way, a joke suddenly came to mind. Some time ago, the old king of Qinghe came to me to say something, and I saw someone selling horses on the way. The horse was indeed beautiful, and it was all black, and there was not even a speck of variegation on its body, and it was as black as coal. He told people the price for half a day, and finally said that it was okay, seven hundred and sixty yuan. He didn't have that much money with him, so he gave his mount to the horse dealer, and rode the black horse to my farm. Don't you see, at that time, the old prince was so proud, his nostrils were facing the sky, and when they met, he boasted to me about his newly bought BMW, and he could see his back molars with one mouth. While praising his ability to take a horse, he praised himself for having a good eye for making a big profit, and patted the horse's neck vigorously. The horse had only run dozens of miles, and he was covered in sweat, but when he slapped him three times, the old prince's hands were dyed black...... "Speaking of this, he lowered his head and went to drink.

Shangguan Rui was listening intently with the tea cup in his arms, and suddenly the story was gone, and he glared at Shang Cheng suspiciously, and the slender lady standing next to him couldn't hold back any longer, and covered her mouth and laughed.

With her smile, the whole room pondered the mystery of the story one after another, and a few little girls with drooping hair couldn't hold it first, holding on to the wall and laughing against the wall so much that they couldn't stand up. The sound of the piano in the corner of the song wall also "squeaked" out of tune. Shangguan Rui raised his head and laughed wildly, most of the tea soup was not wasted at all, and it was all poured on himself. The few kabuki who sat with him were old and shrugging their shoulders vigorously, and the more lively ones giggled and staggered. Chen Pu leaned back with a smile, grabbed one of Tian Xiu's hands and pinched it several times; Tian Xiu smiled and clutched her stomach and lay on the case...... The only Shang Cheng picked up the teacup as if nothing was happening, and drank the water slowly.

Shangguan Rui stretched out his arms and smiled as he asked Shang Cheng, "Did you catch the fake horse dealer?" ”

Shang Cheng shook his head: "I haven't seen the old county king for many days, I don't know if I grabbed it or not." ”

"Hah! The old prince has always boasted of his ability to praise Soma, and this time he lost such a big shame and ugliness, I'm afraid I didn't dare to go out for a while! Shangguan Rui said. He confessed and went out to change his clothes.

Chen Pu couldn't hold back his laughter, and said to Shang Cheng with a straight face: "My fifth grandfather has never provoked you, you go around saying bad things about him, look back and be careful that he won't spare you." ”

"I'm seeking truth from facts, neither exaggerating nor spreading rumors, beware of what he does?" Shang Cheng said, "Besides, now he can't look for anyone, but he doesn't dare to look for me!" ”

This is said with confidence, not to mention Chen Pu, even a room full of kabuki and dancing girls have been aroused by these words. Chen Pu pondered for a while, really couldn't figure out where Shang Cheng's confidence came from, and asked tentatively: "...... Does he have a handle in your hand? ”

"Nope." Shang Cheng said, "But I have an IOU written by him in my hand. If he dares to look for me, that's unbelievable, I can only teach him to pay back. ”

Chen Pu giggled again. At present, for the sake of borrowing money from the three of them, many clans have no money in their hands, and the food, land, utensils, and courtyards of the houses at home are dead things, and it does not mean that they can be discounted if they want to cash money. Moreover, now that all industries in Gyeonggi have withered, the price of land and grain has been declining, and in the past, it would have been sold for 200,000 mu and 200 catties of Shangshangtian, but now it is not worth even 150 yuan. During the Double Ninth Festival, her sister Nanyang also discussed with her and wanted to invite her to partner in buying the 1670 acres of land of the Gu family on the east bank of the Oujia River, but the two sisters couldn't get together the money for a long time, and they didn't want to borrow from Shang Cheng, so they had to put things down first. She and Nanyang also comforted each other, anyway, there are still two or three loans from Dongwei, and the land price will definitely fall, and after a while, the Gu family will really not be able to hold on, and it will not be too late to make a move......

Tian Xiu didn't think there was anything funny about this. She was still worried about the celestial observatory, took a copper pipe, and then said to Shang Cheng: "Uncle Ying, according to your instructions, we have done all the copper pipes and copper caps, and the glass lenses have also been ground out, but we can't make the kind of celestial observatory you said for a long time." Look at ......" Chen Pu also helped, "You can point out the green mountains." She is about to become a member of the patent department, and she can make the celestial sphere, and she can speak harder when the time comes! She speaks hard, doesn't the Ministry of Works' face also have a glow? ”

Shang Yuan came to ramble and said that he didn't know how to do a celestial observatory and an earth-viewing instrument, and he really didn't know how to do it, but Chen Pu said it to this point, and he had no room to retreat. Hey, this guy can really say anything! Tian Qingshan's speech in the patent department is not tough enough, what does it have to do with him? Besides, he is not a secretary of the Ministry of Industry, and if the Ministry of Industry is not glorious, he may not be able to give him a bonus?

He still took the copper tube handed over by Tian Xiu, unscrewed the copper cap, installed a convex mirror at one end and a concave mirror at the other, picked it up and looked at it, and looked out of the white chaos. Changed lenses, it's still the same; If I change the lenses again, I seem to be groggy and seem to be able to see something and I don't seem to see anything, and when I look at it a little more, I feel that my eyes are a little uncomfortable; With another lens, he could see the vague outline of something, but unfortunately he was looking at the opposite wall, and there were only calligraphy and paintings on it, and it was too much to figure out what this vague outline was...... In the blink of an eye, he tried all the twelve lenses upside down, and the effect was the same, he couldn't see anything. He smacked his lips, replaced another copper pipe, and concocted it again according to the law...... The four brass pipes fiddled with each other, and the best result was the combination that could see some outlines just now.

It was a good result, and he wasn't much disappointed. Thinking about it, these lens copper tubes and other things have been tested by the people of the Ministry of Industry, I don't know hundreds of times, so many people have not found a clue, how can he make a major discovery as soon as he takes over? Again, it didn't take long for the Ministry of Industry to make glass, and many problems were not solved perfectly, so the quality of the glass was very unstable. He estimated that the density of these lenses should be very uneven, so the refraction of light seems to be called "refraction", and the refraction of light is also affected, and it is difficult to fit each other to form an effective unit......

He thought wildly, and his hand stopped. He set aside the two lenses that seemed to be useful, and began to carefully search the depths of his mind for the remnants of the telescope. Time is too far away, and all he can recall is the theoretical basis of "small hole imaging", and the others are only some fragmentary terms and one or two small stories with deep memorization. For example, the Italian Galileo made a very famous astronomical telescope to observe the moon and the sun, and this simple telescope was also named "Galileo telescope" after him; Because Galileo used this telescope to observe the sun without tinted lenses, his eyes ended up blinded by the sun's rays. But he seemed to remember in a book in which he read that Galileo had been arrested by the Holy See and persecuted and blinded for propagating heliocentrism...... He also remembers that there was a telescope consisting of three convex mirrors, which was more advanced than the Galilean telescope, and then a reflecting telescope was made with a prism or a metal concave mirror...... The name taught him a little confused. A telescope with prisms involved in the work should be called a refracting telescope, right? How did you come up with the name "reflecting telescope"? Thinking about it carefully, he also vaguely remembered two little stories related to telescopes. There is a story about the Dutch who discovered the telescope: a merchant saw a child playing with two mirrors, and then he discovered the mystery of the telescope in a child's game. Another story tells that when the merchant was inspecting the quality of the lens, he accidentally placed a convex mirror and a concave mirror in a straight line, and then through the lens, he found that the cross on the church in the distance was as clear as his eyes, and then invented the telescope......

He suddenly felt like he had discovered something!

Putting the convex and concave mirrors in a straight line?

Yes, that's the point!

He grabbed the two lenses on the table that were placed next to him alone, the convex mirror was in the front and the concave mirror was behind, and he looked at the calligraphy and paintings hanging on the opposite wall for a little distance, and in an instant, the cursive Li Bai's "Juvenile Xing" was "pulled" to his eyes, and he could clearly see the chubby cursive script at the end of the volume:

"Haozhou Changxiu drunk and splashing ink"

The "black" head of the last word "ink" stretched out his arms and kicked his legs, and he couldn't break the paper out, but the next word "soil" below was not cooperative, and he stood still steadily, resulting in the upper and lower sections of the word "ink" being too distinct, and it looked like two words; Therefore, it seems that the inscription should be read more as "Haozhou Changxiu drunk and splashing black soil"......

“…… Splash black soil! Good calligraphy! Shang Cheng laughed and praised. He stuffed the two lenses to Chen Pu, who was standing behind him and was stamping his feet anxiously, turned his face and pointed to the book sticker and said to Shangguan Rui, who came back from changing his clothes, "I want that "Youth Xing". ”

Shangguan Rui immediately instructed the slender lady to take off Chang Xiu's handwriting.

Chen Pu had already discovered the magic of the two lenses, and looked at all parts of the elegant room. Tian Xiu drew inferences from one another, grabbed the box lens, stood directly by the window lattice, and tested one by one. This is on the third floor, more than four zhang above the ground and nearly five zhang, the field of vision is extremely broad, not only can overlook the entire East City, but also can overlook the imperial city. At this time, it was already the time card, and the twilight was quietly approaching, and the tall bell and drum tower in the distance was like a giant about to fall into a clear sleep, slowly disappearing into the twilight. The Chaotian Temple scripture tower in the southwest corner of the East City took the lead in raising six strings of tulle yellow lights; This seems to be a signal, in the blink of an eye, the lanterns in front of the shops of the various restaurants and tea shops on both sides of the market are gradually lit, and then the twenty or thirty lamp mountain fire squares on the four streets arranged in the word "well" suddenly shine brightly, and the huge East Market, which covers an area of nine squares, instantly became a world of fire trees and silver flowers. At the same time, a large canopy of brilliance also rises more than ten miles away in the west, echoing the colorful East Market. There is the West Market, another bustling destination in the city that never sleeps......

Tian Xiu immediately found three suitable convex and concave mirrors from a box of lenses. Each group could clearly see several lighted arches a mile away, and even after carefully adjusting their relative positions, she could distinguish the large characters on the two archways:

Safe in and out

The family is detailed

This unbelievable sight made her almost uncontrollable with excitement, and her legs and feet trembled a little. She had a strong feeling that she was already standing in front of a towering gate, and with a gentle push of her hand, the world hidden behind the gate would appear in front of the world. And this will be an old and new world......

She breathed deeply, trying to calm herself. What is she going to do now? What should she do? Yes, yes, she wants to record the correct distance between the two lenses! No, it's not! She doesn't need to record that. These documents can be recorded at any time, and then according to this size to make copper pipes and copper caps, it can be completely made into a celestial observatory, although it can only be used to "observe the earth" for the time being! However, as long as she has such a successful experience and slowly explores, one day, she will definitely make a real celestial observatory that can observe celestial phenomena and stars!

No! Can't do that! She immediately dismissed her idea. She couldn't wait to see what the world of that gate was like! She had to see if that world was really as vast and magnificent as Shang Yanshan said. There are stars, planets, moons, sunspots on the sun, moon seas on the moon, and moons on Saturn......

She desperately wants to see the world! She desperately wants to get to know the world! She couldn't wait any longer! Go right away; Now is the time!

Calm down! Calm down. She called out her name, admonishing herself to calm down. Think about what to do now. Think about it, think about it......

Oh yes, Skywatcher! She remembered that the most important thing now was to have a celestial gazetteer! She needs to build the Celestial Sphere before she can use it to realize her dreams.

She turned her head a little dazed, and Chen Pu immediately snatched the few lenses in her hand.

She grabbed Shang Cheng's side and asked eagerly, "How to make the Heavenly Observatory?" ”
