Chapter 50 Achievement Report (3)

Squeezing through the door was a short and thin old man, with a red face and smooth skin, but there was a lack of vegetation on his head, no matter whether he turned the cover left or right, a large part would always be exposed.

Seeing his image, Cheng Jinzhou couldn't help laughing out loud.

Still smiling, Hai Hai stretched out his hand to pat Cheng Jinzhou's body twice and said, "My name is Lu Xu, you can also call me Old Lu."

His hair really needs to be extended.

Cheng Jinzhou was a little embarrassed, and he liked his generosity even more. He also smiled and lowered his head to introduce himself: "My name is Cheng Jinzhou, and I am..."

A basin of icy cold water was poured down his neck. Perhaps because it had just reached freezing point, Cheng Jinzhou even felt that the water had turned into ice, connecting him to his clothes. Under the sudden cold, his body felt cold. Before it was too late to shake, it fell down like an ice cube...

Liu Kuang quickly supported him, and another star warlock behind him unfroze Cheng Jinzhou in a blink of an eye. Xiang Xin lifted his feet and helped him onto the bed.

Lu Xu watched Cheng Jinzhou's upper and lower front teeth trembling, continued to rub his forehead with a smile and said, "Don't think you can stop laughing, I can hear it."

"Old Lu." Liu Kuang squinted his eyes and said to Cheng Jinzhou apologetically, "It's because I didn't take good care of him. Old Lu..."

"It's okay..." Cheng Jinzhou gritted his teeth and could only swallow it. This Lu Xu's shaking of his hand was an astrology, and he came hand in hand with a fourth-level astronomy. He couldn't offend him.

The star warlock behind him took Cheng Jinzhou's pulse for a moment and said softly: "My body is weak and I'm afraid I need to rest for a while."

Liu Kuang's eyes immediately stared at Lu Xu, who smiled stupidly and said, "Just kidding, how did I know he was so fragile."

"He is only 13 years old..." Liu Kuang said solemnly: "When you apologize to others, you are still the one who comes to ask questions,"

"When I was 13 years old, I was already strong enough to kill a cow." Lu Xu said while bowing to apologize. He was short in stature, and when he said that he killed a cow, he had a humorous expression on his face.

The sinister Cheng managed to laugh twice. A basin of ice water was indeed nothing. He had made more annoying pranks, but if this kind of thing happened to him, it would definitely not be interesting.It's just that the situation is stronger than the person. Regardless of whether he apologizes or not, he can only endure it with his head down.

"My name is Wang Linghe, and my nickname is Changhe." The third astromancer interrupted Cheng Jinzhou's association, and while speaking, he used his right hand to float over a distance of more than ten centimeters from his back, and saw the rich steam rising. It looked like it was doing a human barbecue.

After about two or three minutes, Wang Linghe stopped his hand and stood up, saying: "Lv Xu is careless and often does not understand the importance of things. I'm really sorry. I will prescribe medicine for you later. You can rest at home for half a month. You should be able to recover as before, or you can Replenish your energy.”

Cheng Jinzhou didn't want to continue this boring topic, so he asked instead: "Is your skill a medical astrology?"

"There is no such thing as medical astrology." Wang Linghe, who was in his 50s and slightly pale, tapped his slender bamboo pole fingers on the table and said, "I can better judge your pulse and the specific details of the astrology array. Function, please keep it secret."

"I asked the wrong question." Cheng Jinzhou smiled apologetically, feeling the cold air in his body gradually disappearing, and slowly got up from the bed.

After helping him casually, Liu Kuang said slowly: "Actually, I wanted to see you again a few days ago, but I didn't take the time. Xiang Xin asked me a question a few days ago. After reading it, I I can't wait any longer."

"Oh?"

"I've also heard that, you made up a word called critical wind?" Lu Xu also interrupted hastily.

"Calculus, yes." Cheng Jinzhou basically knew the purpose of the three.

People like to say that Newton created calculus, but in fact, calculus has also undergone a long period of precipitation and brewing.Human beings have long been interested in infinity. Zu Chongzhi's pi was born in countless cuts, but it has become a long process to form a systematic discipline.

The mathematics and science level of the Great Xia Dynasty was just at the watershed of the transition from elementary mathematics to advanced mathematics. They had already begun to study some parts, but in many respects, they only had very preliminary ideas.

As a first-level astromancer, the problem Xiang Xin faced was exactly the same problem that the astromancers of the Great Xia Dynasty generally faced.

Although Cheng Jinzhou has never directly answered advanced mathematics questions, he has shown a comfortable mathematical thinking - for real mathematicians, especially mathematicians in the transition period, what kind of thinking should be used to solve problems? is quite important.Elementary mathematics has the ideas of elementary mathematics, and higher mathematics will naturally form its ideological market.This is like when primary school students and high school students face the same chicken and rabbit in the same cage problem. The former must think about the relationship between numbers, while the latter's first reaction should be a linear equation of two variables.

Different ideas determine different solutions.

However, it is impossible for Cheng Jinzhou to pass on the calculus knowledge he knows to Liu Kuang and others, even if he pays for it.One is that he cannot make a rigorous proof and deduction process, and the other is that this is also his greatest advantage.

Thinking of this, Cheng Jinzhou asked in an evasive manner: "This is just my preliminary idea. It has not yet been proven to be correct..."

He was still worried that Liu Kuang would continue to ask, and did not want the latter to nod noncommittally, and then said seriously: "Cheng Jinzhou, are you interested in serving as a consultant to the Hexi Transportation Department?"

The Transshipment Commissioner is the secretariat of the Transshipment Commissioner's Yamen, the so-called think tank, and Liu Kuang's question is to invite Cheng Jinzhou to join Liu Bin's field division team.

As a fourth-level star warlock, his solemn tone is already considered an honor.

Cheng Jinzhou remained silent. The Cheng family had a vested interest. If he hadn't considered face, he would have refused directly.What his cheap father-in-law, Comrade Liu Bin, did was purely thankless.

Liu Kuang said in a slightly praiseworthy tone: "The several suggestions you have made have greatly helped the progress of the project. You are talented in this area..."

Seniors appreciate juniors so much, just like a director supports an actor, a boss takes care of a secretary, they all have a purpose.

If he was a child who was not experienced in the world, he might have been deceived by Liu Kuang, but Cheng Jinzhou was half lying on the bed calmly. He looked around and said, "I don't know how many contribution points it will take to replace the star formation on your body." arrive."

"I am a level 2 star warlock, and I spent 4000 points using a level [-] star formation." Lu Xu couldn't speak for a long time, scratching his head and head anxiously, finally finding a question he could answer, and he couldn't remember the prank just now.

"4000 points is so expensive." Cheng Jinzhou looked at the ring on his hand - Zhou Papi was the same Zhou Papi, and Yang Bailao each had his own usury.

Lu Xu said triumphantly: "It took me 20 years to switch to this star array, and many people are afraid that it will take 50 to [-] years."

Cheng Jinzhou was stunned.It's quite a scary thing for an astro-warlock to work for 20 years. Even if he just robs a bandit bank every day, after 20 years, he still has no problem buying four or five Cheng's.

Liu Kuang was still waiting to persuade, when there was a loud noise outside the door, the volume was getting louder, and it was mixed with crying and howling, and before a few people asked, a servant reported: "Someone was crushed to death in the temple in the west of the city. "
