An airship is like a luxury yacht in the sky, it has a faster degree than a ship, more space than an airplane, and of course, a more expensive price, even for an astral warlock, it is a high-level luxury.

The interior of the boat is luxuriously decorated, and the wall curtains are made of silk and edged with silk, which wraps the surface. The floor is covered with a thick wool carpet, soft fur covers the top of the feet, and low tables made of cowhide, deerskin, bear skin and other precious furs are randomly locked on the edge of the corridor for people to temporarily rest and talk. Paintings and calligraphy are framed in conspicuous places, and considering the weight and factors, wooden or stone materials are rarely used on the ship, but when properly designed, it will give people a sense of solidity, which can even be regarded as psychological research.

Cheng Jinzhou went up one floor and found the captain's lounge in the rear cabin, the door was closed like other rooms, Xiao Cheng knocked with some hesitation, and then said: "Liu Kuangxing Warlock? ”

"Jinju." Liu Kuang's slow voice came from inside, and the door opened silently.

In the room, Wang Linghexing Warlock and Liu Kuangxing Warlock were both there, each holding a quill pen, and they were actually doing calculations on the whiteboard.

Cheng Jinzhou was quite surprised: "You guys are starting to study now?" ”

Liu Kuangxing Warlock didn't look back, and said with a meaningful smile: "Time doesn't wait for me, at any time, you can only climb to a higher point to better enjoy the scenery below." ”

If it was two or three days ago, Cheng Jinzhou might have laughed and fooled the past, that is, just like his previous life. The children of the gentlemen can always find a shortcut to the south, but when they can't find it, they often have no way out. As for now, seeing the huge power of power and the loss of dignity without power, Cheng Jinzhou didn't dare to hesitate anymore.

However, he was a gentleman after all, and he had the idea of forging ahead, but he didn't have any physical movements, just stupidly watched the two astrosorcerers draw and write there, and didn't even have a clear sense of direction - in fact, there was nothing he could study: he either hadn't learned medieval mathematics, or he didn't know much about it, and it was difficult to copy in short; There is no problem in the use of modern mathematics, and if you want to reproduce the verification process, it is far beyond the scope of the ability of the cheating doctor; Modern mathematics is the focus of his study, but Cheng Dù, who is barely 6o points, wants to research something new on his own—that is the work of Dr. Cheng's father and Dr. Cheng's mother, not a category that he can access as a cheating doctor.

Perhaps, growing up quickly is what is needed the most, Cheng Jinzhou thought very strangely in his heart.

Seeing that he was idle, Liu Kuang simply threw him a pen and said, "You also come and try?" Xiang Xin is not here, and we are doing it slower. ”

Cheng Jinzhou waved his hand again and again: "I'm here to thank you." ”

He didn't dare to really go into battle, even if he did a simple question, the simplified process, the degree of reaction, and the mastery of formula proficiency would affect the degree of presence, Cheng Jinzhou was worried that he would be exposed in two minutes.

Liu Kuang thought he was modest, shook his head and smiled: "I've already thanked him, if you really want to say thank you, help me make a picture." ”

With that, he turned around and said, "We're going to split this figure now." Jinju, you can try to find its extreme value and range. ”

Cheng Jinzhou was fortunate that the Great Shun Dynasty, or Liu Kuangxing, chose to derive the equation from the trajectory, rather than studying the equation first and then deriving the trajectory, the former being Descartes' research direction and the latter being Fermat's research direction. In contrast, Fermat's ideas were more natural, closer to ancient Greek thought, with a strong classical color, while Descartes was slightly deviant, but his work was also more groundbreaking – Descartes proved to be more of a contributor to the mathematics exhibition, so that students mostly used Descartes as a model for their research, and Cheng Jinzhou did the same.

Perhaps it is precisely because the astrologers do not agree with Greek classical mathematics such as Euclidean geometry, so they are more able to develop from their own needs, and they can be regarded as getting into the familiar category of Cheng Jinzhou.

Dr. Cheng Da held the pen, his right eye glanced at the progress of the Wang Ling Hexing Warlock, and slowly calculated the extreme value, not daring to go forward or lag behind, the end was very painful, fortunately, the problem was quite simple, and he deliberately skipped the calculation steps, and tried to get the answer directly, so as not to be the thinking and calculation methods of the times.

Liu Kuang didn't notice this problem, but while processing the entire figure, he asked intermittently: "Your results in balance design last time, I have already helped you submit ...... to the association, and after the review is passed, there should be a response ......, and you still have 6 contribution points to reach a one-star warlock...... Don't worry, after all, if someone wants to use your results, they need to complete their research and submit it again to the association...... There won't be much association contribution in a short period of time, and everyone is very slow to write...... But a 1-star warlock is only 1o points......"

He remembered to say one sentence at a time, if he was thinking or calculating, he would pause for dozens of seconds, and let him speak for five or six minutes in just a short paragraph, and Cheng Jinzhou, who listened to it, was sleepy, but he was just pretending to calculate. He knows best the time and energy it takes to write a mathematical paper, in fact, relying on plagiarism to complete an inferior mathematical paper also wastes a month's guild CD, how many people can read his results report and not say it, after reading the report, he still has to use it, and he can use it and write a paper that is recognized by the Star Warlock Association, which can increase his contribution a little, so that the number of selections is naturally very small. Last time, if it weren't for Liu Kuangxing's introduction from Warlock, he wouldn't have been able to get 4 points of association contribution very easily.

Therefore, there is no need for Liu Kuang to explain, Cheng Jinzhou did not put his mind on obtaining the contribution points of the association, this must be a long-term work, once it is persistent, there will be high returns, but it is very unrealistic to make short-term profits.

In about 1o minutes, Cheng Jinzhou completed the calculation of the extreme value of a partial function, hung it on the whiteboard and handed it to Liu Kuang for synthesis. The latter glanced at it twice, and then praised: "Yes, some parts are better than what Xiang Xin handled, but the process is too simplified." ”

As he spoke, he frowned and said, "Your way is a little too ......."

"It's not formal, I learned it myself, so ......" Cheng Jinzhou explained the not-so-genius thing in a genius tone.

Liu Kuang nodded noncommittally, frowned tightly and said, "Cheng Jinzhou, do you think it makes sense to find the maximum and minimum values of a curve?" ”

This sentence is not asked casually, although it is the maximum and minimum value that he asked Cheng Jinzhou to do, but whether it should be done and whether it makes sense to do so is another question, and it is a very important question.

Cheng Jinzhou was speechless for a while, not knowing how to answer, as a famous public case in the history of mathematics. Descartes insisted that there was an essential difference between "straight" and "curved", that only straight lines had definite values, and therefore rejected any exploration of the length of curves, and attacked Fermat's maxima and minima as contrary to strictly deductive reasoning—there was no Descartes among the astrologers, but the same question would still be asked, just as people would want to know the result of four times five, and then they would like to know the result of four times six.

For the astromagicians, the determined number is quite useful, the value of the curve is often in the calculation, if you insist on the difference between "straight" and "curved", it is equivalent to giving up the practicality of analytic geometry, Liu Kuangbiao xiàn is more confused than Cheng Jinzhou expected, because he is taking the route of Descartes, but unconsciously has to use a similar way to solve the problem, although the Great Xia Dynasty did not have Fermat and Descartes, but the animals of the pros and oppositionists will always survive on the same soil.

"I'm not sure." Cheng Jinzhou didn't even dare to shrug his shoulders.

Liu Kuang actually didn't expect Cheng Jinzhou to solve such a theoretical problem, so he just stretched his waist and said: "At this year's association, Jiang Huangxing Warlock is afraid that it will be difficult. ”

"Is he also a fourth-level star warlock?" Cheng Jinzhou asked cautiously. The creatures called the fifth-level star warlock are extremely rare, and with Cheng dù of the Great Xia Dynasty, the fourth-level star warlock is the top.

Wang Linghe echoed and said, "Is it a royal star warlock, a fourth-level star warlock, or a four-star warlock." ”

The star of the star warlock is more valuable than the higher the level, and the second-level star warlock may be more powerful than a two-star warlock, but when it reaches the third and fourth levels, it is often not as valuable as the star warlock of the same star, and except for a few people, the level of the high-star star warlock is often very high. Liu Kuangxing Warlock is a fourth-level star warlock and a three-star warlock, and it can be said that in terms of theoretical star art, he has somewhat fallen behind.

The high-level struggle of the star warlocks is not something that a small shrimp like Cheng Jinzhou can understand, he can only laugh twice and say, "Liu Kuangxing warlock will definitely win." ”

"Hopefully." Liu Kuangnunu mouthed and said in a very confident tone: "If you can occupy the commanding heights on this issue, I think that by the time of the next term, it will not be a problem to become a four-star warlock, Cheng Jinzhou, are you interested?" ”

"Huh?"

"I need a bigger team to do this." Liu Kuang knocked on the whiteboard and said, "You also want to learn astrology systematically, most of the astromagicians in my team have undergone formal training." ”

Except for freaks like Cheng Jinzhou, I'm afraid there are very few star warlocks who are not formally trained. Cheng Jinzhou raised his eyebrows and excused himself: "I can't help much." ”

Ever since he joined Liu Bin's Transit Envoy, Liu Kuangxing Warlock seemed to have been trying to pull him onto the ship, and the more he did, the more he didn't dare to agree.

Warlock Liu Kuangxing was also familiar with his temperament, and he didn't force it, but only put on a new whiteboard and said, "Let's move on to the next proposition." ”

It seems that he prefers to create a fait accompli.

As long as he doesn't get involved in some complicated whirlpools, Cheng Jinzhou doesn't mind being intimate with a few star warlocks, and when he arrives in the capital, this relationship is probably his only reliance.

The time to start the problem always passes quickly, especially in the process of using knowledge, if it is smooth and smooth, it is also quite a pleasant thing. Liu Kuang will not give Cheng Jinzhou the difficult part, in the initial stage of research, many of the contents have been studied by Cheng Jinzhou step by step, and it is extremely smooth to do.

By the time Xiang Xin returned to the cabin, she basically didn't have to do anything anymore, so she had no choice but to give the three of them a hand, her understanding of mathematics and physics was barely a very good and serious freshman, and her vision and other aspects could not be compared with Cheng Jinzhou at all. Not to mention the fact that it is in the new elementary stage of analytic geometry.

Cheng Jinzhou sighed while doing it, the astrological sorcerers' mathematics exhibition is too unbalanced, such as trigonometry functions, practical geometry is studied a lot, but other theoretical content is rarely touched, and he is also a doctor of theoretical physics, replaced by a doctor of mathematics, he has to be angry, anxious and depressed to death.

I don't know how long it took, the servant knocked on the door gently, and after getting Liu Kuang's response, he pushed the door open and said, "Masters, lunch is ready." ”

"What are you going to eat today?" Xiang Xin was bored to death, so he hurriedly asked.

"Cod with chicken sauce, thin lamb chops with iron fire, sake-flavored floating skin, assorted vegetarian grilles, and two jugs of sake." After the servant knelt down, he went out backwards, and the space on the airship was limited, and the rules had changed.

"This chef of mine, the thin lamb chops are very good, try it." Liu Kuang stretched his waist, stood up and said with a smile: "The lamb chops are all taken from the lamb of about 2o catties, as long as the three ribs in the middle, with a little edge of fat, once the fire passes, the oil is almost burned clean, but there will be a little bit wrapped on the meat, which is very tender." ”

"I'm drooling over what I said." Cheng Jinzhou said kind words.

"It's not easy to cook on an airboat, and the dishes have to be prepared below. That's why it's hardest to walk long distances. ”

Cheng Jinzhou couldn't help but want to pat his head when he heard this, this airship is a little slower, but it is absolutely smooth, and the comfort Cheng dù is at least at the level of a private jet in later generations, even if it is a long-distance flight, it is more comfortable than an ordinary luxury mail ship, it seems that the fourth-level star warlock is also a picky master.

Xiang Xin cleaned up the whiteboard next to him, and when Cheng Jinzhou was ready, he took out a silk cloth pouch from under the table and handed it to him: "This is today's Cheng Yi, please accept it." ”

Xiao Cheng took it for some reason, and his hand sank, and he couldn't help but wonder: "This is ......"

"The star warlocks participate in this kind of discussion, and they are all taken by Cheng Yi." Xiang Xin blinked narrowly and said, "The bundle I gave you is from here." ”

Wang Linghe and Liu Kuangxing both smiled and nodded to him and walked out the door.

Cheng Jinzhou himself lagged behind and poured out the contents of the silk bag on the table. It is exactly 4 small silver ingots, no need to use your hands to check, only from the top of the twisted out of the suit, you can know that it is the standard Kuping silver - the silver put in the imperial court's inventory, the standard 1o two, usually only used for large transactions, rarely circulated in the market, so there is less wear and tear.

If it is a normal food price range, 4 taels of silver can read 10,000 words, 4o taels of silver can read 1o million words, the daily salary is just enough to buy a book from the library, if the library books are regarded as equivalents, his daily salary is about 3o yuan, 2o days a month to calculate, the salary is 6oo yuan, in a small city like Shaonan, it is really barely the level of living, how similar to its situation.

Of course, 8o taels of silver per day was still very terrifying in the Great Xia Dynasty, and the monthly income of 16oo taels of silver was more than the income of most shops. Cheng Jinzhou was secretly speechless, it seemed that a star warlock without a rank seemed to be quite rich - as a guy valued by a fourth-level star warlock, it was difficult for him to understand the life and mentality of a low-level star warlock.
