Night.

Li Yi and his son had a showdown in the Hunan restaurant.

didn't drink a sip of wine, and sprayed bitterly for half an hour, completely stupidizing Li Zheng.

"That's it. Li Yi clipped a pair of chopsticks and a double pepper fish head, "For girls, sex before the age of 18 can easily cause lifelong gynecological diseases, even after the age of 18, it is important to keep clean, take good measures to protect each other." ”

Li Zheng looked at the white rice in front of him blankly, and only then did he have room to interject: "I understand the truth, but I should be a man, right?"

"Do you think that the girl's gynecological disease is caused by herself?" Li Yi's eyes widened, and he became more and more severe, "It's not all caused by those stinky boys who don't have common sense of hygiene." Look at Liu Xin's father, who is so old that he will still have surgery for the people around him. ”

"Right...... I'm sorry......" Li Zheng lowered his head and thought for a long time, "No, why should I apologize?"

Li Yi didn't pay attention to him, and was still talking to himself: "Although, your mother and I have known each other since the first year of high school, but the first behavior was after marriage, and in this era, it is not easy to be harsh on you, but at least after the sophomore year, well, 20 years old is almost 20 years old." ”

"Can this kind of thing be planned?"

"It's restraint, restraint at critical moments. Li Yi poked his head and said softly as if teaching martial arts secrets, "If you don't restrain yourself, trying to go further too early will create a frivolous impression on the other party, which is very unfavorable to the follow-up progress, which is all my experience." ”

"You're enough, I don't need this experience. Li Zheng couldn't bear it anymore, and ate with his head bored, "The chemical competition is not over yet, there are physics competitions, information competitions, mathematics competitions, and ...... And what, there's a competition to play anyway, what do I want to do with this experience?"

"It's all said that it's open, don't pretend with Dad. Li Yi continued to teach, "I have explained the physiological attention points, the following is psychological, there is a type of girl, for various reasons, they inevitably lack fatherly love in life, and the situation they show is usually sensitive, delicate, and not good at expression, when interacting with her, don't play with a child's temper, and take the ...... of a man."

“……”

Under Lao Li's teachings, Li Zheng was inexplicably forced to accept a series of strange knowledge.

There is a feeling that I am going to be forced to go on a blind date.

……

At eight o'clock in the evening, the canteen of a certain unit was still full of people.

Mother Lin took Lin Yujing to eat, and found a seat in the corner to sit down.

"Hmm......" Lin Yujing didn't look at the food in front of her, but looked at the people who were in a hurry around her.

As they walked, they talked about data and experiments, in short, terms and numbers that they didn't understand at all.

From time to time, someone nodded at Mother Lin, and left in a hurry, and then peeked from a distance, happily pointing.

Mother Lin smiled helplessly, leaned out, and gently broke her daughter's face back: "Okay, don't look at it, I also violated the law anyway, wait for fewer people, and then take you to visit secretly." ”

"Hee-hee. Lin Yujing smirked and scratched her face, "Can you see it...... Is it really a rocket?"

"That can only be seen at the production and launch bases, here are just laboratories, there are only samples and scaled-down models of some modules. Shen Tinglan held his chin with his left hand, and gently mixed the food with his right hand, "This project is planned to be launched at the Wenqiong base next summer, if it is just in time for your vacation, I can help you book a room nearby, so if you like it, just see it with your own eyes." ”

"Hmm!!" Lin Yujing's eyes suddenly glowed with gold, and she lowered her head and took a big bite of food.

Shen Tinglan looked at her daughter, and her first reaction was to laugh.

But then I wanted to cry again.

She turned her head, stroked her nose and asked, "Jingjing, do you know what that means?"

"Ahh ”

"I mean, what does this path mean for your personal life? ”

"Build a rocket! ”

"In this way, you can eat slowly and listen to me. Shen Tinglan breathed a sigh of relief.

She spoke unhurriedly, as if whispering on her pillow.

"Mom used to be like that, just like you. ”

"I'm completely obsessed with the only thing I want to accomplish. ”

"And your dad also met in the process. ”

"Young people, their hearts are always full of ideals and goals. ”

"It's ridiculous to think that I can fight for this for the rest of my life. ”

"Even when I was pregnant, I would work in the hospital for more than 10 hours a day. ”

"Completely ignoring your dad's feelings. ”

"So much so that when you were born. ”

"I just realized he didn't come. ”

"He went abroad, to the best chemistry school in the world. ”

A few years later, he returned as an associate professor. ”

"We went through the divorce process and we didn't have any grudges against each other. ”

"I didn't know at the time that he gave all the $50,000 he had saved in those years to your grandfather. ”

"Finally, when we parted, he asked me out of the blue. ”

"In the end, I married him, or I married the aerospace industry. ”

"I don't know how to answer. ”

"He doesn't seem to be asking for any answers, if you have difficulties in life, or need help, you can contact him at any time, and he is also willing to take you over to raise you. ”

"After that, you grew up day by day. ”

"I didn't tell you anything. ”

"But you're still in love with it. ”

"I've never asked you to study hard. ”

"But you're still learning so well. ”

"Now you're going to race, and you're going to have a lot of choices. ”

"I have to tell you that every road has something to gain and something to lose. ”

"Now, maybe it's your last chance. Shen Tinglan breathed a long sigh of relief, avoided his daughter's gaze, and looked at an empty corner, "Do you want to go to the magnesium country?"

“？？？”

"If you really go down this path. Shen Tinglan stroked the table table suddenly, "For the sake of national security, and for your safety, it will be difficult to leave the country in the future, so it is necessary for me to tell you in advance that you have a father, in the magnesium country, his life is better than everyone you have seen, and his status is higher than everyone you have seen, he is willing to accept you, give you a better education, and a bigger stage." ”

"But there's no way he's going to come back. ”

"It's even more unlikely that I'll go over. ”

"And you, you have the right to choose your own future. ”

Boom!

Lin Yujing suddenly slammed the table hard.

With his head down, his teeth creaked.

"I hate him. ”

"Hate chemistry. ”

"I loved it here. ”

"Loved Mom. ”

"Don't hear anything about him again. ”

"Anything!"

Shen Tinglan turned his back and wiped his eyes: "Okay, I will never mention this matter again." ”

Seeing this, Lin Yujing's mouth suddenly softened: "Yes...... Sorry ......"

"It's okay, I've never been sad about him. Shen Tinglan turned around and smiled, lowered his head and picked up the food, "Emotionally, my mother is a failure more than anyone else, there is really nothing to say." I just hope that you can meet a man who is like you, who is really ridiculous enough to fight for a career all his life. ”

"Hmm~" Lin Yujing breathed a sigh of relief and lowered her head to eat, "The boys are stunned, how can there be a rocket to be fun." ”

"Well, that's what I thought too. Shen Tinglan chuckled, "The Li Zheng I saw when I was out of school, was he particularly stunned?"

"yes, yes. Lin Yujing replied subconsciously.

After a long time, my face suddenly turned red and choked

"Hiccup. ”

"Nervous about what? Keep eating. Shen Tinglan hid his face and smiled.

"Not what you think...... Hiccup, that kind of ......"

"I didn't think about anything. ”

"You think about it, hiccup, isn't it Mr. Tang'......? ”

"Hahaha. After Mother Lin laughed, she suddenly raised her eyebrows, "It's not good to say anything else, don't trust the man who studies chemistry." ”

"Hiccup, he doesn't like chemistry either, he didn't sign up, Hiccup. ”

"Oh oh, I'm concerned. ”

"Hiccup, I'm angry, Hiccup!"

……

The next day, Li Zheng started a transaction with Xu Mengxi and Zhang Xiaoke respectively.

I harvested more than a dozen pounds of test papers and exercises.

At night, I turned on the computer that I hadn't touched for a long time, as well as Visual Basic.

Visual Basic is a programming software that the teacher talked about in the computer class of the first year of high school.

Very old and simple.

Maybe it's even simpler than the "key wizard".

In this day and age, VB has almost no practical value, but because it is based on a graphical interface and is incredibly easy to use, it is still suitable as a programming enlightenment software.

Of course, this is also the only programming software that Li Zheng has entered.

When it comes to programming, it's certainly about more than just an information contest.

Computers are undoubtedly very core research tools, and researchers will use computer software to perform a large number of simulations and calculations, and a considerable number of the software is designed and programmed by researchers themselves.

You don't have to go too far, but programming languages are always an important skill in the learning process, especially the more you go.

To put it mildly, in the Dragon Ball group, the information competition is also to be engaged.

It just so happens that Teacher Mengxi needs help, so you might as well start today and realize a small idea little by little.

Li Zheng's idea must be related to learning.

He had been looking for a long time to find a software that could discover his knowledge weaknesses and provide targeted tutoring and exercises according to people's conditions.

Of course, I didn't find it.

In this era of big data, whether it is listening to songs, watching videos, brushing Zhihu or shopping, it has been refined to each user and accurately pushed information.

But only learning, there is no software tailored to people's conditions.

It's just incomprehensible.

It seems that all the R&D energy in the industry has been invested in exchanging homework answers and online courses, which is naturally good, but compared to these, there are obviously more efficient ideas, so why not use them?

Of course, maybe this road is not going to work commercially.

But this does not prevent Li Zheng from doing some programming training by himself.

Right now, he needs a program that is so simple that it can even be done with Excel.

That is to list all the detailed knowledge points of the discipline.

Then look at Xu Mengxi's recent exercises and relate them to the knowledge points.

If you do it right, add one point to that knowledge point, and if you are wrong, subtract one point.

Finally, according to the score, Xu Mengxi's mastery of each knowledge point was listed.

Then, push tutorials and exercises for reinforcement.

From now on, Xu Mengxi does not have to waste time by blindly doing questions, but only does questions that can improve her.

The principle is very simple, and in fact, it is also done a lot of times in class exams.

It's just that...... The amount of data is somewhat large.

Moreover, it is a very professional and patient job to associate each question with the corresponding knowledge point and select the best push questions.

Probably only Li Zheng himself has this interest.

Although there are many difficulties.

But this night, an engineering document called "Demon Learning and Cultivation System" was finally established.

……

Friday, lunch break.

Li Zheng stepped into the first class of the third year of high school with high spirits.

Holding a large stack of printer paper in his hand.

The face is full of majestic hair.

The students in the first class have long been surprised by this.

even took the initiative to call "Brother Zheng".

The girls, but instead called Li Zheng "sister-in-law".

Li Zheng didn't understand this logic for 5 minutes.

Lao Tzu's abdominal muscles have been trained, is it difficult or not fierce enough?

Under the watchful eyes of everyone, Li Zheng slapped a whole stack of papers on Xu Mengxi's table: "Thank you for using it, the hospitality is not good." ”

Xu Mengxi, who was sleeping on his stomach, "whoosh" and startled.

The first reaction was to push Li Zheng out.

But seeing that she was surrounded by people in the class, she had no choice but to give up treatment.

Before she had a seizure, the onlookers were shocked at first.

"Damn, there's something on this watch!"

"Subject grading?"

Even the little girl who was coaxing in the front row came over: "How did you calculate this, sister-in-law Xi?"

"Go, go, go. Li Zheng waved his arm and said, "Do you want to look at your abdominal muscles?"

"Yes. The girl nodded repeatedly.

"Okay, I'm scared to death!" Li Zheng grabbed the corner of his clothes, which was about to be teased.

"Enough, wow!" Xu Mengxi hurriedly pressed Li Zheng, "I know, I know, you're a macho man, okay." ”

"Just kidding, Mr. Mengxi. Li Zheng smiled, "Come, look at the software feedback." ”

"Hmm......" Xu Mengxi looked at the table on the first page.

This is her score for each subject, all on a 100-point scale.

Basically in line with her previous test scores, with Chemistry being the highest (87) and Mathematics being the lowest (66).

"Did you average my previous score?" Xu Mengxi said, turning to the second page.

Immediately afterward, a circle of people around shouted: "Woo!"

It's just that the second page is too deep.

【Mathematics Knowledge Mastery】

[Meaning and Representation of Collection: Excellent]

[Basic Relationship Between Collections: Excellent-]

[Basic Operations on Sets: Good]

……

[Exponential Functions and Power Operations: Good-]

……

[Stratified Sampling: Medium]

……

[Calculation of non-equal difference and proportional series: medium +]

……

Among them, the "excellent" rating is indicated in green, which means that it is no longer necessary.

Good is indicated in yellow, which means not strong enough.

Medium use orange, it is recommended to focus on conquering.

Poor use of red, which means a mess.

Turn the page again.

In addition to language and English, other disciplines also list such knowledge maps.

"You...... You, you, you ......" Xu Mengxi was about to cry, "How much work have you done......"

"What do you call work, it's an interest, and thank you for providing data. Li Zheng said and turned a page, "Next, it is all for the intermediate and poor knowledge points of the push tutorial and exercises, you can only carry out targeted learning, no need to brush the whole textbook or exercises, you can rest assured that the questions I push are absolutely accurate." ”

"It's not...... It's not ......," Xu Mengxi quickly flipped through the pages, "You have to use it for dozens of hours......, right? I don't deserve ...... wow."

"Eh, it's just half an hour to make a program, and these are all given by the program. Li Zheng smiled and waved his hand, got up and said, "After completing these questions, you will give me feedback and re-rate." ”

"Don't!" Xu Mengxi followed and got up, "Please, don't delay me any longer, okay, it's about to be a chemistry final......"

"Please don't say that again. Li Zheng raised his hand and walked away, "If you say something like this, your friend won't have to do it." ”

"Cocoa ......"

"That's right, it's time for me to enter Zhang Xiaoke's data later. Li Zheng finally stood in front of the door and waved his fist lightly, "Jingbei is indeed still a little far away, but this is not the reason why we give up shortening the distance, wait for you to hear back." ”

With that, the macho man turned around and left with his hands.

"Ah......" Xu Mengxi sat down blankly.

In the end, it's a super oil bottle.

But......

Since it has been dragged so much.

Then try again and shorten the distance.

Li Zheng's side walked all the way to the staircase, but was suddenly stopped by a group of people.

"Brother Zheng, I want it too. ”

"Sister-in-law Xi, you are a macho man, a super macho man!"

"Don't make a fuss. Li Zheng waved his hand, "It's very troublesome, it took me dozens of hours." ”

"Isn't it an automatic feedback from the program?"

"That's what I expected after the data was abundant in the future......," Li Zheng coughed and reluctantly admitted, "At this stage, I still manually input and output, and the program is actually just something like an Excel sheet." ”

When a group of bigwigs heard this, they were also silent, and it was not good to entangle them anymore.

They are all people who have to face the college entrance examination, who would be idle and have nothing to do to pay dozens of hours for another person?

"That ......" the girl in the front row stepped forward tentatively, "I'm screaming macho men, I don't believe you have abs, let me touch it." ”

"Please. Li Zheng riveted.

How to rivet it is about like.

The girl stepped forward and touched it, and she really touched the tough outline: "Damn! Sister-in-law Xi is really a macho man." ”

The girl next to him immediately came up: "Really? I don't believe it either."

"Believe it or not, I touch it too. ”

While Li Zheng was dodging, Qiao Bixia suddenly appeared, and stood up with her sleeves to greet her: "What are you doing?

Li Zheng jumped down the stairs in an instant, and went down half a floor in only two steps.

After escaping back to work, Li Zheng gave her Zhang Xiaoke's share again.

Zhang Xiaoke didn't talk so much nonsense, and immediately burst into tears.

"Master...... Master ......" Zhang Xiaoke shook Li Zheng's shoulder and said, "How do you sell this software......?"

Li Zheng shook his shoulders wildly and scolded, "Aren't you going to challenge Jingbei? ”

"Do, do, I'll do it all. Zhang Xiaoke turned around and rolled up his sleeves, "Since I apprenticed, I don't know why, when I see a question type I haven't seen before, I will be very energetic for some reason." ”

"That's right, this is your Huigen. ”

Jiang Qinghua in the rear shuddered.

Are you sure it's not karma?

"I'm almost about to start. Li Zheng immediately shook his head and took out a copy of the "Catalysis and Materials Chemistry Graduate Teaching Series" from his schoolbag, "I will finish studying the graduate students, probably I will never need to touch chemistry again in this life......

At the same time, Tiantan Hospital, a dozen kilometers away.

Li Yi's mobile phone rang, a lot of sounds.

[Dear Mr. Li, the amount of credit card repayment in this period: 18223.42 yuan]

[Congratulations, Donggejia Supreme Plus member LZ will give you VIP status for one month, please click to receive ......]

[Your bank card is 4XXXXXX, and you received 17,542.66 yuan in "salary credit".] 】

No way.

Behind the bubble of learning.

Someone has to really cut the meat.
