Chapter 80 Geometric Optics (4)

Walking out of Hongwen Hall, Xiang Xin began to talk about some optical geometry problems that came to his mind, but Shen Cong covered his mouth, held back for a while, and finally laughed loudly.

Cheng Jinzhou couldn't help but smile.

Seeing Shen Cong's smile almost rolling all over the floor, Xiang Xin didn't understand, so he said, "Is there something wrong with what I said?"

The laughter got louder.

There were sergeant guards at the entrance of the Hongwen Hall, and Shen Cong walked forward with his stomach in his hands, before he said, "You don't know the cause and effect, then Lu Anping was showing off the two contribution points he had already got in front of his classmates, and 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 rubbed his head and said helplessly, "I didn't want to argue with him..."

"It doesn't matter. You said his surname is Lu, and he is in the Hongwen Museum. He is probably the little prince Lu who studied with Deng Zhuo Xingshi." Xiang Xin explained, "Deng Zhuxing is Jiang Huangxing. My apprentice, a second-level star warlock, a second-level 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, he found the carriage he had come from, and headed all the way to the association.She is the apprentice of a fourth-level star sorcerer, and she never has to think about things other than research, and she doesn't pay attention to a foreign prince.

As for classmate Xiao Cheng, although he had long thought that he would offend someone, he didn't know that he offended so quickly and so inexplicably.But after thinking about it, since Lu Anping is proud of his talent as an astro-manager, he will eventually come to him.It's a pity that the family really can't help, otherwise, as the son of the Cheng family, he definitely won't have the slightest strength to fight back.

No matter how many royal favors there are, they are nothing more than foreign vassals. If Cheng Jinzhou has a family as the backing, at most he will be suppressed by others. Now he is a bit out of control.The imperial court may give preferential treatment to the children of the aristocratic family because of the state of Shaonan, 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 only felt pressure all over his body, as if he had fallen into a thick paste, so that he would not die, but it was extremely difficult to move around.

For any person in the Great Xia Dynasty, since the beginning of his birth, his basic status has been determined. Afterwards, he may be able to raise a class or two, but with the power of a generation, there are few people who can jump several levels in succession. ——From slaves to free people, from commoners to nobles, from nobles to aristocratic families, from localities to the central government, the further you go, the more effort is needed.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."

"That's up to you to be ready." Cheng Jinzhou laughed, he had enough articles in the ring memory, after a quiz, he was really not afraid, and he still had the heart to joke at this moment.

"It's good that you have astrology..." Shen Cong patted his forehead. It's hard to say too much next to Xiang Xin, and in his opinion, it's very hard to get 2 contribution points from the Astrology Association.Lu Anping is also considered to have outstanding aptitude in the Hongwen Museum, and he has only accumulated 2 points in a short period of time.He secretly decided in his heart that when the time came for the township examination, he must buy a copy of the examination questions for Cheng Jinzhou.

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

"Three articles have been completed."

"Can I watch it?" Xiang Xin said a little embarrassed. She was obsessed with astrology, but she was in a normal state among the astronomy practitioners.

"There is a draft." Cheng Jinzhou thought with a smile and said, "It's too troublesome to go back and get it, so I'll write it here for you."

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

Cheng Jinzhou laughed a few times, and started writing on his stomach.The report he submitted was absolutely plain and simple. With the same word size, the information contained in the previous report may only be one-tenth of the previous report, and the "main content" is 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 full of fear of the unknown.Cheng Jinzhou obviously can consciously control the progress, so he is naturally unwilling to rush forward blindly.There is no medical school and white rats 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, but in order to explain why, it takes a lot of articles.Cheng Jinzhou still divided it into three parts according to his own report method. Even so, it took less than half an hour.When he turned around, he saw that there were more than a dozen plates full of all kinds of seasonal snacks, cold dishes, and even a pot of rice wine in front of Shen Cong.

"The hors d'oeuvres of the association are very famous." Shen Cong stuffed his mouth with something to drink, and smiled casually while drinking: "I used to come to the Astromancer Association, and I could only watch it from outside. Once, I wanted to sneak into the archives. , and was found kicked out, who would have thought that such a single room existed in the association, tsk tsk—"

No wonder he admired it, the astrologists are extremely wealthy, not to mention Xia Jing's branch, the decoration of the rooms is done without regard to cost.A single room of [-] to [-] square meters, they turned it into a semi-open lounge and living room, as a whole, like a high-end hotel in later generations.The walls and the ground are covered with soft carpets, and the exquisite craftsmanship makes it even more artistic. The potted plants that have been cultivated over the years are inserted directly into the roof, which is unique...

Let alone Shen Cong, even Cheng Jinzhou would be surprised by such a design.

Xiang Xin may have watched too much, just looked at the schematic diagram of light reflection drawn by Cheng Jinzhou as if she hadn't heard it, and chatting with a dozen or so pieces of paper on the desktop was more attractive to her.

Shen Cong brought out a few dishes in the middle, and then gave him clean chopsticks, "Try these dishes. Everything here is good, but the service is not good enough. When you bring things into the room, it's too late." do not care."

"Then what else do you want?" Cheng Jinzhou seldom had the chance to go out to eat after time travel, so he thought it was very interesting.

The two of them relaxed and ate happily. When someone knocked lightly on the door, the table seemed to be licked by a dog...

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

"In Xiaxu Valley."

Cheng Jinzhou hurriedly got up, cleaned up 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 aside before opening the door.

Xu Gu stood at the door with a smile on his face, holding a small 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 too high, but after all, it is a real skill, which is different in the hearts of young people.

"Is Mr. Cheng Jinzhou here?" Xu Gu was polite and considerate, he didn't neglect Shen Cong just because he was a teenager, and he was completely different from the carelessness of many astrologists, so 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'm bothering Mr. Xu again today."

"If every astrologer can bother me every two or three days, my work will be easy." Xu Gu raised the notebook in his hand with a smile and said, "I have received all three reports of yours, and they will be released on the same day." Please have a famous astrologer look at it, it was put into the treasury 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 are compulsory courses for nobles, and he has learned them proficiently.If the report passes the preliminary review, it means that it is eligible to obtain contribution points. For Xiao Cheng, it is regarded as having contribution points.

Hearing the sound, Xiang Xin stood up with a sigh of relief, smiled at Xu Gu, and then continued to say to Cheng Jinzhou: "I have a feeling that I have more ideas. If you need experimental equipment, there are many suitable ones in the outer peninsula, which should be available for you." Experiment, this is really a good topic."

Optics is of course a good topic. If you have all the materials in hand, Cheng Jinzhou can play for 200 years with this alone.Thinking about it, he smiled and said, "I don't need too much equipment now, if I need it later, I will trouble you."

He didn't show Xiang Xin the version of the submitted report, otherwise, if there was a small mistake in it, he might be caught, and that would deviate from the original intention.

Here, Xu Gu said with emotion: "There are a lot of rented equipment in the outer peninsula, and it's good to use occasionally. Last time you said that you want to exchange contribution points, it is to buy equipment and experimental materials. The results are produced in a few days, which is really amazing." .”

He wrote a thesis in 3 days, and the plagiarized version can be regarded as the speed of a leopard and the strength of a bear. Cheng Jinzhou sneered in his heart, and smiled like oil on his mouth: "I have prepared for a long time, and it is the last blow."

Xiang Xin looked at the pictures drawn by Cheng Jinzhou again, and suddenly said: "You should go to the outer peninsula with me. I see that what you need most for your work is all kinds of crystals and glasses, and then you need a lot of measuring instruments. , These are easy to find on the island, and as for funds, if you can’t find them for a while, you can do some work for other astrologists, which is also a good way to raise funds.”

It is common for star warlocks to work for star warlocks, especially for high-level star warlocks. After reaching the back, they can hire people everywhere after they contribute more points.Level astromancers who need to update the star array must work hard.

Where does Cheng Jinzhou really need experimental equipment? He still can't figure out the level of equipment in the 17th century, so he quickly refused, "I just need to buy some materials recently."

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

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

"You can say it in the letter, and my answer is more perfect..." Cheng Jinzhou smiled at Xu Cong with a tight face, and escaped from the Astrology Association as if fleeing.

……

Niaoyu: Due to insufficient consideration, the setting of getting one contribution point at a time for reading had to be revised, and it is still a point for quoting at a time.In fact, in the latest chapters, I have already used the revised setting. I thought that everyone might forget the previous statement, so I didn’t explain it again, but after all, some great readers remembered it and asked in the book review area, so I re-explained it In theory, it should not affect reading.

In addition, this chapter is today's Chapter 2, calling for a monthly pass.
