Chapter 80 Geometric Optics (4)

After walking out of Hongwen Hall, Xiang Xin began to talk about some optical geometry problems that he had thought of, but Shen Cong covered his mouth, held back for a moment, and finally laughed loudly.

Cheng Jinzhou couldn't help but smile.

Seeing Shen Cong laughing so hard that he was almost rolling on the floor, Xiang Xin asked inexplicably: "Is there something wrong with what I said?"

The laughter grew louder.

There were still sergeants guarding the entrance of Hongwen Hall. Shen Cong walked forward with his belly in his hands and said, "You don't know the cause and effect. Lu Anping was originally showing off the two contribution points he had received in front of his classmates, but he didn't want to..."

When he said this, Xiang Xin also laughed and added: "Unexpectedly, Mr. Cheng has already sold two contribution points..."

Coupled with the rich expression of the person he saw before, Xiang Xin smiled even more freely.

Cheng Jinzhou touched his head and said helplessly: "I didn't want to argue with him..."

"What does it have to do with it? You said his surname is Lu and he is in Hongwen Hall. He is probably the young prince Lu who studied with Warlock Deng Zhuxing." Xiang Xin said and explained: "Warlock Deng Zhuxing is Warlock Jiang Huangxing His apprentice, a second-level star warlock, a second-star warlock, nothing special."

"It's a troublesome thing after all." Shen Cong sighed and said no more.

Xiang Xin didn't care about this, found the carriage he came from, and headed all the way to the association. She is the apprentice of a fourth-level star warlock. She never has to think about things other than research, and she doesn't even pay attention to a prince from a foreign vassal.

As for Xiao Cheng, although he had long thought that he would offend someone, he had no idea that he would offend someone so quickly and inexplicably. But then I thought about it, since Lu Anping was proud of the star warlock's talent, he would eventually come to his door. It's a pity that his family can't really help, otherwise as the legitimate son of the Cheng family, he would not be able to fight back at all.

No matter how many honors and favors the prince of a foreign vassal has, it is just a foreign vassal. If Cheng Jinzhou had a family to back him up, he would be suppressed at most. Now he is a little unable to do anything. The imperial court may give preferential treatment to the children of aristocratic families because of Shaonan Province, but it will not provide any protection for a down-and-out nobleman.

Born in a society with a strong sense of class, Cheng Jinzhou felt that there was pressure all over his body, as if he had fallen into a thick paste. It was extremely difficult to move around without dying.

For anyone in the Great Xia Dynasty, their basic status has been determined from the beginning of their birth. After the struggle, they may be able to rise one or two levels, but with the power of one generation, few can jump several levels in a row. ——From slaves to free people, from commoners to nobles, from nobles to aristocratic families, from local to central government, the further you go, the more efforts you need from more people. The only exception to this is becoming an Astromancer.

Cheng Jinzhou leaned back slightly, letting his body sink into the thick fur, and his eyes swayed with the ups and downs of the carriage. Since arriving in the capital, he had devoted all his energy to writing a thesis, so he was not anxious. On the contrary, Shen Cong, not knowing what Xiao Cheng had to rely on, whispered: "You must be prepared for this provincial examination."

"Then you have to be ready." Cheng Jinzhou laughed. He already had enough articles in Jiezi Memory. After a small test, he was really not afraid. He still wanted to joke at this time.

"It doesn't matter if you have astral magic..." Shen Cong patted his forehead. It was hard to say too much next to Xiang Xinxing Warlock. In his opinion, two Star Warlock Association contribution points were also very difficult to obtain. Lu Anping is also considered to have outstanding qualifications in Hongwen Hall, and he can only accumulate 2 points in a short period of time. He secretly decided in his heart that when the provincial examination came, he would buy a copy of the test questions for Cheng Jinzhou. With his fame, he would have more room for maneuver.

The carriage swayed to the Star Warlock Association. Xiang Xin took out his certification stone, asked for a single room in the library, and asked impatiently: "Do you have a completed report?"

"Three articles completed."

"Can you see it?" Xiang Xin said a little embarrassed. She was obsessed with astrology, but this was normal among the astrology group.

"I have a manuscript." Cheng Jinzhou thought and smiled: "It would be too troublesome to go back and get it, so I'll just write it out for you here."

Xiang Xin quickly took the white paper and quill pen and laid them out on the table for him. He stared at the paper and said, "If it's too much, just write the main part. I'll think about it slowly when I go back."

Cheng Jinzhou laughed twice, then lay down and started writing. The report he submitted was absolutely simple. With the same word count, it contained perhaps only one-tenth of the information in the previous report, and the "main content" was actually not much.

This was done without him having to say it. Everyone thinks that a good paper will attract many people to cite it. However, due to the circulation conditions of the Great Xia Dynasty, unless it is mainstream content that is popular, there will always be a lag period for information. In many cases, a good paper will It's not necessarily true that there are several ordinary papers. Of course, ordinary papers also need to have real materials.

People are always afraid of the unknown. Cheng Jinzhou could obviously control the progress consciously, so naturally he was unwilling to rush forward blindly. There are no medical schools or white mice in this era, but don’t expect more good people and less curiosity...

The simplest geometric optics can be expressed clearly with only one picture. In order to explain clearly why, it takes a lot of articles. Cheng Jinzhou still followed his own reporting method and split it into three parts. Even so, it only took less than half an hour. When he turned around, he saw that there were more than a dozen full plates in front of Shen Cong, including various seasonal snacks, cold dishes, and even a pot of rice wine.

"The association's cold dishes are very famous." Shen Cong stuffed his mouth with food and drank wine casually and said with a smile: "When I came to the Star Warlock Association, I could only watch from the outside. Once I wanted to sneak into the library. , and was even found out and kicked out. Who would have thought that there would be such a single room in the association? Tsk tsk——"

No wonder he admired that the Star Warlocks were extremely wealthy, not to mention Xia Jing's branch, and they decorated the rooms regardless of cost. A single room of fifty or sixty square meters was turned into a semi-open lounge and reception room, making the whole room look like a high-end hotel in later generations. The walls and floors are covered with soft carpets, and the exquisite carvings add a touch of artistic flavor. The potted plants cultivated over many years are inserted into the roof, which is unique...

Not to mention Shen Cong, even Cheng Jinzhou would be surprised by such a design.

Xiang Xin may have read too much, and just looked at the schematic diagram of light reflection drawn by Cheng Jinzhou as if she didn't hear anything. Talking about a dozen pieces of paper on the table attracted her even more.

Shen Cong took out a few dishes placed in the middle, and gave him clean chopsticks: "Try these dishes. Everything is good here, but the service is not good, and things are not brought into the room." do not care."

"Then what do you want." After time travel, Cheng Jinzhou rarely had the opportunity to go out to eat, but he found it very interesting.

The two of them were in a relaxed mood and ate quite happily. When someone knocked on the door gently, the table seemed to have been licked by a dog...

"Who is it?" Shen Cong yelled at the door.

"I'm in Xia Xu Valley."

Cheng Jinzhou quickly stood up, cleared away the leftovers on the table and said, "It's the person in charge of the local association."

Shen Cong also quickly got up. Wrap all the tablecloths and put them to one side before opening the door.

Xu Gu stood at the door with a smile, holding a notebook that had not changed for thousands of years.

"Hello." Shen Cong was a little nervous. The status of a second-level star warlock is not that high, but after all, it is a real skill, which makes a difference in the minds of young people.

"Is Mr. Cheng Jinzhou here?" Xu Gu was polite and considerate. He did not show any disrespect because Shen Cong was a young man. He was completely different from the carelessness of many star warlocks. It was no wonder that he would be the head of the local association.

"I'm here." Cheng Jinzhou came out from the side and said hello with a smile: "I have troubled Mr. Xu again today."

"If every star warlock can trouble me every two or three days, my job will be easier." Xu Gu smiled and raised the notebook in his hand and said: "I have received your three reports, and I will give them to you on the same day." I asked a reputable star warlock to look at it, and it was put into the warehouse yesterday."

The famous star warlocks he mentioned are often not necessarily famous, but as long as they can distinguish the good from the bad and identify the deficient ones, it is enough.

Cheng Jinzhou began to be humble as usual. These were compulsory courses for nobles, and he became proficient in them. If the report passes the preliminary review, it means that it is qualified to obtain contribution points. For Xiao Cheng, it is regarded as having contribution points recorded in the account.

Hearing the sound, Xiang Xin sighed and stood up, smiled at Xu Gu, and then continued to talk to Cheng Jinzhou: "I feel that there are many interesting things that are not yet exhausted. If you need experimental equipment, there are many suitable ones in the outer peninsula, which should be able to provide it for you." Experiment, this is a really good topic.”

Optics is of course a good topic. If the information at hand is complete, Cheng Jinzhou can play for 200 years with this alone. He thought to himself and smiled: "We don't need too much equipment now. If we need it later, I'll trouble you again."

He didn't show Xiang Xin the version of the report he submitted, otherwise the minor errors in it might be caught, which would deviate from the original intention.

Xu Guze here said with emotion: "There are a lot of rental equipment in the outer peninsula, and it's good to use it occasionally. Last time you said you wanted to exchange contribution points, it was just to buy equipment and experimental materials. The results were produced in a few days, which is really amazing. .”

Writing a paper in 3 days, the plagiarized version is considered to be the speed of a leopard and the strength of a bear. Cheng Jinzhou cursed in his heart, and said with a smile as if oil was applied on his lips: "I have been preparing for a long time, just the last blow."

Xiang Xin looked at the pictures drawn by Cheng Jinzhou there again, and suddenly said: "You'd better go to the outer peninsula with me. I think your work needs all kinds of crystals and glass, and then a lot of measuring instruments." , these are easy to find on the island. As for funds, if you can’t find them at the moment, you can help other star warlocks complete some work, which is also a good way to raise funds.”

It is common for Star Warlocks to work for Star Warlocks, especially high-level Star Star Warlocks. Later on, when they contribute more points, they can hire people everywhere. The leveled star warlocks who need to update the star array must work hard even if they don't have to.

Cheng Jinzhou really needs experimental equipment. He still can't figure out how to handle the 17th-century equipment, so he quickly refused: "I just need to buy some materials recently."

With that said, he pulled Shen Cong sharply and said, "Where did you say your pawn shop was today? Go there first while you have time."

Xiang Xindeng said anxiously: "I still want to ask you a few questions."

"You can say it in the letter, and my answer is more complete..." Cheng Jinzhou gave Xu Cong a stern smile and ran out of the Star Warlock Association as if he was running away.

…

Birdsong: Due to insufficient consideration previously, the setting of getting one contribution point per reading had to be revised. It is still one point per citation. In fact, I have already used the revised setting in the recent chapters. I thought that everyone might forget what I said before, so I didn’t explain it again. But after all, some great readers still remembered it and asked about it in the book review area, so I explained it again. It should theoretically not affect reading.

In addition, this chapter is the second chapter today, calling for monthly votes.
