The one who squeezed into the door was a short and thin old man with a red face and smooth skin. He had a lack of vegetation on his head. Whether he was pushing the lid left and right, a large piece was always exposed.

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

The Mediterranean still smiled and reached out to pat Cheng Jinzhou twice and said, "My name is Lu Xu, and I can call Lao Lu."

His hair really needs to be continued.

Cheng Jinzhou felt a little embarrassed and had a good impression of his generosity. He also smiled and lowered his head to introduce himself: "My name is Cheng Jinzhou, it's..."

A basin of cold cold water poured into his neck. Perhaps because it had just reached the freezing point, Cheng Jinzhou even felt that the water had turned into ice and connected himself with his clothes. After the sudden cold, his body could not shake, and he poured down like ice...

Liu Kuang quickly supported him, and another astrology warlock behind him thawed Cheng Jinzhou in the shiny left rib. Xiang Xin raised his feet and helped him onto the bed.

Lu Xu watched Cheng Jinzhou's upper and lower front teeth tremble, and continued to touch his forehead with a smile: "Don't think you can hold back the laughter, I can hear it."

"Old Lu." Liu Kuang stared at his eyes and shouted, then said to Cheng Jinzhou apologetically: "It's me who takes care of Buzhou, Lao Lu..."

"It's okay..." Cheng Jinzhou bit his teeth and could only swallow it. Lu Xu's hand was a star technique, and he came together with a fourth-level star sorcerer. He was not something he could offend.

The astral warrior behind him took Cheng Jinzhou for a moment and whispered: "The body is in a weak and weak way, so I'm afraid I'll have to rest for a while."

Liu Kuang's eyes suddenly glared at Lu Xu again, and the latter smiled foolishly and said, "Just kidding, how could I know he is so crispy."

"He is only 13 years old..." Liu Kuang said in a deep voice: "I apologize to others, you are still the one who comes to ask questions,"

"When I was 13 years old, I was so strong that I could kill the cow." Lu Xu said, bowing and apologizing. He was short and said that when he killed the cow, the expression on his face was very humorous.

The black-bellied Cheng reluctantly laughed twice. A basin of ice water was indeed nothing. He had made a prank that he hated even more annoying, but it would definitely not be interesting if this kind of thing happened to him. It was just that the situation was stronger than that of others. Regardless of whether he apologized or not, he could only hold back his head and endured it.

"My name is Wang Linghe, nicknamed Changhe." The third astrology warlock interrupted Cheng Jinzhou's association. While speaking, he used his right hand to float past him more than ten centimeters from his back. He saw a rich steam rising, as if he was doing a human barbecue.

After about two or three minutes, Wang Linghe stopped and stood up, saying, "Lu Xu is careless and often doesn't know the importance of it. I'm really embarrassed. I'll prescribe you later. I'll rest at home for half a month. It will recover as before and replenish your vitality."

Cheng Jinzhou didn't want to continue this dull topic, so he asked instead: "Your skill is medical astrology?"

"There is no medical astrology." Wang Linghe looked over 50 years old, with a slightly pale face. He knocked on the table with a slender bamboo pole finger: "I can better judge your pulse and the specific functions of the star array, so I'm sorry to keep it confidential."

"I asked the wrong question." Cheng Jinzhou smiled apologetically, feeling the air conditioning on his body gradually faded, and he slowly got up from the bed.

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

"oh?"

"I heard that, you created a word called "Qiqifeng?" Lu Xu also interrupted in a hurry.

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

People like to say that it was Newton who created the calculus, but in fact, calculus has also been precipitated and brewed for a long time. Human beings became interested in infinite infinity very early. Zu Chongzhi's pi was born in countless cuttings, but to form a systematic discipline, it became a long process.

The mathematical level of the Daxia Dynasty was just in the watershed between the transformation from elementary mathematics to advanced mathematics. They had already started to study some parts, but in many aspects, they only had very preliminary ideas.

As a first-class star sorcerer, the problems facing Xiang Xin is the problems facing the star sorcerers of the Daxia Dynasty.

Although Cheng Jinzhou had never answered advanced mathematics questions directly, he showed a kind of mathematical idea that was easy to solve problems. For real mathematicians, especially mathematicians in the transition period, it is very important to use what kind of ideas to solve problems. Elementary mathematics has the idea of ​​elementary mathematics, and advanced mathematics will naturally form its ideological market. This is like primary school students and high school students who face the same problem with the same chicken and rabbit in the same cage, the former must think about the relationship between numbers, while the latter's first reaction should be binary equations.

Different ideas determine different solutions.

However, it was impossible for Cheng Jinzhou to pass on the knowledge of calculus that he knew to Liu Kuang and others, and it was impossible even if he paid for it. First, he could not make rigorous proof and inference processes, and second, this was also his greatest advantage.

Thinking of this, Cheng Jinzhou asked in a slight way: "This is just my initial idea. It has not yet, and it cannot be proved to be correct..."

He was also worried that Liu Kuang would continue to ask questions, but he nodded without comment. He turned to the scene and said seriously: "Cheng Jinzhou, are you interested in being the consultant of the Hexi Transportation Commission?"

The Transportation Commission is the secretariat of the Transportation Commission’s Office. The so-called think tank is also the case. Liu Kuang asked this question, but Cheng Jinzhou was invited to join Liu Bin’s field division team.

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

Cheng Jinzhou was still silent. The Cheng family was a vested interest. If it were not for the question of face, he would have refused directly. His cheap father-in-law, Comrade Liu Bin, had done nothing but pure thanklessness.

Liu Kuang said in a slightly praised tone: "The suggestions you have made great help in the project. You are talented in this regard..."

The seniors admire the younger generation so much, just like the director helping actors and the boss taking care of the secretary, all of which have a purpose.

If he was a child who was not well-informed in the world, he might have been deceived by Liu Kuang, but Cheng Jinzhou was half lying on the bed, looking left and said, "I don't know how much contribution points do you need to change to the star array on your body."

"I am a second-level star warrior. I spent 4,000 points with a level 2 star formation." Lu Xu couldn't speak for a long time, and was so anxious that he scratched his head. He finally encountered a question he could answer, and he couldn't remember the prank he had just done.

"4,000 points are very expensive." Cheng Jinzhou looked at the ring on his hand - Zhou Pai is the same Zhou Pai, and Yang Bailao each has his own marks.

Lu Xu said proudly: "I have used it for 20 years to exchange for this star array. Many people are afraid it will take forty or fifty years."

Cheng Jinzhou is as stupid as a wooden chicken. It is a terrifying thing to work in a 20-year-old star warlock. Even if you just grab a bandit money house every day, there will be no problem in buying four or five Cheng families in 20 years.

Liu Kuang was waiting to persuade him again, and a noise came from outside the door, the volume was getting louder and louder, and there were also cries and howlings. Without a few people asking, a servant reported it: "There was a death in the temple in the west of the city."
