Demon Development System

Biquge www.wuxiaspot.com, the fastest update of the latest chapters of the learning magic cultivation system!

2019, the first day of the opening year.

Li Zheng worked hard all day to become a real old programmer.

There is still a little more than half a year before the information contest. It stands to reason that this should not be done so early.

But the upgrade of learning magic software is imminent.

At the end of January, the district entrance exam is coming. Even if Li Zheng does not need this software, Mengxi teacher and dog apprentice Zhang Xiaoke will also need it.

They have already finished the special question bank before, and now is the time for the second round of checking for gaps and challenges, and challenging the ranking.

To this end, Li Zheng did not hesitate to spend more than twenty minutes, studying the basic algorithm, data structure and database content.

Then it took another ten minutes to rewrite the 0.1 version of the learning magic cultivation system with C++ ideas.

Also known as the personalized dynamic question bank version.

If there is no BUG, ​​you only need to enter the results of the previous brushing questions, and the learning magic system can re-evaluate the level of each subject and each knowledge point of the user, and give the second round of question banks.

What is stupid is that at this stage, you can only manually enter the results of the brush questions, and then manually select the questions.

To really achieve high-efficiency learning feedback, on the one hand, you need a huge question bank, on the other hand, you also need to develop a "knowledge question" or "online brush question" function, let AI judge and write the result, and then based on the result, from Select targeted questions in the total question bank to achieve output.

This is not just a programming problem, but also involves a lot of data and algorithms, which is far from being solved by Li Zheng at this stage.

All he can do is to manually enter the selected topics into the database, and encode and group them according to their difficulty and corresponding knowledge points. Although the efficiency is extremely low and the salary is not enough, it is finally the first step.

In addition, if this personalized learning system can really be realized...

Teachers in extracurricular tutoring classes are afraid of losing their jobs.

Is it possible to add a terminator to the front of the title?

...

On January 2nd, the first day of the New Year's school, the day before the start of the physical training classes.

The first thing Li Zheng entered the school was "to explain what happened next."

In the first three grades of high school, everyone is already surprised at Li Zheng's arrival.

Xu Mengxi also accepted the reality and completely gave up the idea of ​​banging him out to speak.

Li Zheng pinched a piece of paper in his left hand, carrying a few pounds of questions in his right hand, and walked to the table in one step, presenting the paper.

"Mr. Mengxi, this is your data change, the progress is obvious."

"Ah..." Xu Mengxi looked at the data table, his jaw slowly stretched out, beyond amazement, more doubt.

【Mathematics: 66→73】

[Exponential function and power operation: good-→ excellent -]

[Relationship and calculation between convex polyhedrons: difference→medium+]

...

【Physics: 78→82】

【Power in closed circuit: medium→good-】

"This... this... is this really calculated by the software?" Xu Mengxi couldn't bear it, but he said it by biting his lip, "Is it all calculated by yourself?"

Li Zheng frowned, very dissatisfied: "What a joke, you are insulting an old programmer, I am only responsible for entry and printing."

"I...I don't believe..."

"Go back and compile a stable version of Windows and send you a copy." Li Zheng said, lifting the plastic rope in his right hand.

Boom!

Eight catty exercises hit the table.

"These are based on your current situation, the feedback of the targeted questions should be enough for you to complete the final exam." Li Zheng looked at the small half-meter-high questions and said, "Don’t forget to turn over the book if you have difficulties, ask me OK."

Xu Mengxi felt more and more distressed.

The final exam is coming soon, and we must prepare for the physics competition.

Li Zheng spent so much energy on me...

Not to mention repaying, even the words of thanks are not enough.

"Please... don't do this anymore... I don't know what to say..." Xu Mengxi was so anxious that he suddenly remembered something, turned around and turned over his schoolbag, "Yes, the gold medal should also be Back to you……"

But she finally found the gold medal and raised her head.

Li Zheng has already slipped out of the classroom.

"!!!" Xu Mengxi threw the air into the air in a rage, "This is the case every time, leave without saying hello, and leave."

Behind him, Qiao Bixia was looking at her like an old mother, with a smile on her face.

"Okay, according to my understanding of this kid, he is actually learning smoothly. Didn't you say that he was going to do all five major competitions and secretly complained that he was not specific..."

Like eating gunpowder, Xu Mengxi turned around and pressed it on Qiao Bixia's mouth: "Okay, stop talking!"

"Hahaha!" Although Qiao Bixia was pressed, she could laugh. "I can't think of it-you have a bigger mouth than your hands. I just said that he is not specific in learning, what are you excited about."

"What?" Someone in the front row looked back in surprise, "Li Zheng is not focused?"

Another person: "Li Zheng Huaxin?"

"Li Zheng pedals two boats?"

"Li Zhengzhan male?"

"Li Zheng is too much!"

At this moment, Xu Mengxi realized deeply, what is the meaning of Shu Yujing and the wind.

...

A similar scene was staged in the second and fourth grades of high school.

It's just that the taste is heavier.

After all, Zhang Xiaoke is not so easy to feed.

"The 12-pound question is not enough." Li Zheng piled the exercises next to Zhang Xiaoke's desk, and said with a whimper, "Mathematics, Physics and Chemistry has increased by more than 30, which is worthy of my apprentice."

Looking at this big question, even Zhang Xiaoke swallowed.

"Master, you have hundreds of paper money, right?"

"Don't think about it, follow me, the question is enough." Li Zheng said, clapping his hands and returning to the table to sit down, "Chong Jingbei, the question must be done by Jin Jin."

"Our teacher, the taste is heavy..." Zhang Xiaoke touched the heavy question dam and sighed while looking at his transcript. "Since this is the case, there is no need to say any words of thanks. I will do it. do."

"There is ambition." Li Zheng's heart moved with laughter, "Laughter," "At the end of the district entrance exam, you can't see your original classmates, you can also see your ranking, and it's time for you to be an individual."

"!!!"

Li Zheng laughed: "At that time, you will generously say to your classmates that you are overtaken, just work hard and be strong."

"Master..." Zhang Xiaoke looked at Li Zheng with tears in his eyes. "How should I repay you in the end? Or... give you a fork? I have practiced dancing."

"Who wants to watch this."

"Well?"

A familiar voice came, and Lin Yuejing stopped behind the two carrying the kettle: "It depends on the split."

"Don't hack you." Zhang Xiaoke's eyebrows closed, looking back alertly. "From now on, I am completely with Master, you have to be careful."

"嘁~" Lin Yujing turned to his seat, "Your master has fallen into a training class."

"It's an improvement class," Li Zheng scolded far away. "It's your loss if you don't go. Wait, we will be two worlds in a week."

"Oh." Lin Yuejing turned to sneer, "When have you been to a world?"

"Fuck." Li Zheng thumped the table fiercely.

Indeed... never reached a level...

But this time is really different, and the physics contest can never fail.

Damn, why wait until April...

It's too long to bear.

Take the final exam as a killer.

As he was saying, Liu Xin rushed into the classroom and ran to Li Zheng's mobile phone without putting on his schoolbag: "There was a force to post the performance video in the bar, Li, you are going to be famous!"

Li Zheng raised his eyebrows tightly, looking at the screen.

[City 1 School X Yinghu Middle School X New Year’s Eve Performance Shows All Musical Instrument Masters]

At this time, the section playing the Conan Saxophone was played. The definition was very low and the jitter was severe. It seemed to be taken with a mobile phone.

The barrage also flew out one after another.

[Now that middle school students are so powerful? 】

[Is Sakura Lake a conservatory? 】

[This man is also the champion of the National Chemistry Competition...]

[Unclear sister! Is there a clear version? 】

[Ha ha, Li Zheng in our school is a real big brother! 】

Looking down further, although there are only a few thousand views of the video, there are a lot of comments. Many people from City One and Sakura Lake commented and introduced the background.

Looking at it, a radiant Jiang Qinghua leaned over and kindly reminded: "It's almost time for class, almost."

Everyone is unfamiliar with this positive tone and full of vitality.

But looking around, it was indeed Jiang Qinghua.

"Oops!" Zhang Xiaoke exclaimed, "It's the sour smell of love."

"Ah? Hey!" Jiang Qinghua waved his hand with a smile, sat back in his seat, organized his beloved schoolbag, and sighed a thousand times. "What are you talking about? Just watch a movie and eat together. I didn't expect it for so many years. In the future, I will watch "My Neighbor Totoro" in the cinema."

"Mother!" Zhang Xiaoke said with a head in his head. "It's been so hard to kill you for the first time."

"What's the matter?!" Liu Xin put away his cellphone and sat back in his seat. "Who? Tell me."

Jiang Qinghua only smiled and waved his hand: "It's time to call the preparation bell. I'll talk back.

Li Zheng saw that the wood had become a boat, so it was not easy to persuade him to study.

After all, Du Shitong is a city school, and his grades must not be too bad.

Interacting with such people does not necessarily affect Jiang Qinghua's study.

But in case it was the existence of Zhang Xiaoke before, it is hard to say.

Jiang Qinghua is his own after all, Li Zheng still subconsciously helped him get up.

"How is she studying?"

"It's not much to talk about...it seems to be in the middle rank..." Jiang Qinghua said, "But the middle school in the city's first school is definitely better than me."

Li Zheng couldn't help but ask: "Specifically? Is Chinese good or math good? What competition did you participate in?"

"You ask what these are doing..."

"My dad always said that he wants to be the right person, I don't want to help you plan." Li Zheng said, "The scores of each subject are measured. Is it worthy to continue to develop? Do you want to send others too much? It will not take long. There will be many contradictions."

Jiang Qinghua swallowed and said: "Li Zheng, who is not...men don't mean that."

"We are still middle school students, which is almost what it means." Li Zheng palmed, "When people take a test of 985, you are not even 211, get along together, have you been in your own heart?"

"...This...but..." Jiang Qinghua's cheerful face sank unconsciously again, covered with a touch of frost. "After all... people are from a city school... even if It’s just the midstream...985 is not a big problem...I seem...it really doesn’t deserve her..."

"Hello..." Zhang Xiaoke couldn't see it anymore and said, grabbing Li Zheng's shoulder. "Master, you... don't be like this. Qinghua is happy for two days...you are too humane... "

"No, no." Jiang Qinghua grabbed her hair fiercely. "Li Zheng is thinking for me. I really should recognize myself..."

"Don't be too pessimistic. You have the space to work hard." Li Zheng patted Jiang Qinghua's hands on the table gently. "I have a system of learning demons here that can be opened to everyone." Test, intelligent questions, no matter how much you send others, make it a dozens of pounds of paper, you will be able to climb high, do you want to try?"

Jiang Qinghua's eyes lit up: "Oh? The one for Zhang Xiaoke and Xu Mengxi?"

Excited by him, he did not see Zhang Xiaoke and Liu Xin shaking their heads frantically.

"Yes." Li Zheng answered.

"May I?" Jiang Qinghua asked again.

"of course."

"That's me." Jiang Qinghua nodded sharply, and then suddenly worried. "Just... what did you just say, Jin?"

"Don't care about these details." Li Zheng rubbed his hands. "Come to my house after school and bring all the papers you have done this semester. I will guarantee you a five-pound question."

"Can you... stop talking about it, I'm afraid..."

Li Zheng smiled generously: "Eh, I'm not afraid when I'm doing it. I don't believe you and ask Xiaoke."

"Ah... this..." Zhang Xiaojue saw that Jiang Qinghua was still involved, and he sighed. "People are different... I can only say, come on, work hard, please be strong."

...

That night, Jiang Qinghua came out of Li Zheng's house at half past ten.

Holding a U disk worth five catties in his hand.

噔噔.

The phone rings.

Jiang Qinghua glanced down and rarely smiled.

[Poetry boy: After finishing homework, go to bed. 】

[Jiang Qinghua: I didn’t move a word...]

【Poetry Boy: Are you busy with the monitor's work? Hard work. 】

[Jiang Qinghua: I mean, my day has just begun, and it will be 100% overnight tonight. 】

[Poet boy: Don’t do this... staying up late is very inefficient, and... your hairline is already much higher than your peers... I suggest you work hard to maintain it. 】

Jiang Qinghua rubbed his hair and suffocated for a while.

This... this is starting to disgust me?

[Jiang Qinghua: But I... The school is sending you too much, if you don’t work hard...]

[Poet boy: ah? What do you want this to do? I’m not too good...the score is at most 985 in the middle and lower reaches...]

Jiang Qinghua was another suffocation.

985 is a goal I dare not think of.

But in Du Shitong.

It’s just...

Only...

Sure enough, the difference in learning has led to the difference in the three views.

Faced with the same thing, opinions and visions will be very different.

At this time, I said that 985 is very powerful, and I dare not think about it...

It will only be despised, and then it will lose the common topic, and then separate because of the incompatibility...

Li Zheng is right again. It turns out that there is really a right to study.

[Jiang Qinghua: It’s okay, don’t think too much. I just want to be admitted to the same university as possible if possible. 】

[Poetry boy: (blushing) (blushing) (blushing)]

[Poetry boy: Is it possible to ensemble in school occasionally (blushing)]

[Jiang Qinghua: Of course! 】

[Poetry boy: I get it, then come on! Sleep at least two or three hours. 】

[Jiang Qinghua: Obey! 】

[Poetry Boy: Let's work hard at the end of the joint entrance exam. According to the ranking of the district, we can almost launch the college entrance examination ranking. Then we will discuss the school... (blushing)]

[Jiang Qinghua: Very good! 】

Li Zheng's statement was fulfilled again.

The meaning in the poem fairy tale is obvious from the academic results.

If her academic performance cannot reach the same level as her...

There is simply no future!

In the dark night, Jiang Qinghua strenuously stared at the bicycle, Ren Changfa fluttered.

I get it, Li Zheng.

Learning is the most important.

What is the hairline?
