Learning Demon Cultivation System

"For...for..." Lin Yujing scratched her head, a little messy, and finally had no choice but to answer, "Although I really want to see Huang Er try his best to turn the tide, I was actually dragged here... I didn't expect myself to be able to really play What effect."

"Your judgment is very correct." Du Songtao said with a satisfied smile, "I don't expect myself to be able to play any role. If Li Zheng thinks that he can do something, he is out of his mind. But this does not affect us to try something, Do you still remember our principle?——Pick those jobs that are amazing if they are successful, and will not be too criticized if they are not.”

"Yeah." Lin Yujing nodded in conviction, "Well, I'm on my way."

"What about you?" Du Songtao turned to Li Zheng, "Do you accept this attitude?"

"Reluctantly accept it." Li Zheng nodded. "The basic task is to learn. You can do as much as you can on top of that. If Huang Er still fails to launch after the internship period, I will continue to help as a part-time job."

"Okay, then the attitude is unified, let's talk about the rules." Du Songtao raised his hand and said, "First, get off work on time at six o'clock in the evening, and anyone who wants to work overtime will move out of this office."

"Support!" Lin Yujing clapped the book and applauded.

"Tch." Li Zheng only tilted his head.

Du Songtao continued.

"Second, during non-working hours, don't disturb me because of work. If it's drinking, chatting, or going to a party, of course I support it."

"Third, don't be lazy during working hours, use every minute to work hard, don't do stupid things like staying up late to work and then catch up on sleep during the day, I only need a clear brain and abundant inspiration here, if you think you don't have these two things, go home and rest go."

"Okay, the rules are finished, the following is the work policy."

"We have limited manpower and only do head work."

"Research and dig out fault inspiration and reliable clues."

"And then throw these things out to people outside, and they will naturally follow up desperately."

"We use this time to find the next inspiration."

"Until we get reliable conclusions and determine effective solutions, we will maintain this work cycle."

"You may think that such an approach is unfair to outsiders, but we are half laymen after all. Inspiration and interdisciplinary perspectives are our strengths. We should give full play to this strength instead of getting bogged down in redundant work."

"So, start now, find your inspiration, try to dig something out."

After Du Songtao was stared at by the two for a long time, he waved again: "I'm done talking, let's go."

Li Zheng scratched his head in confusion: "Aren't there any specific instructions?"

"Didn't I give instructions?" Du Songtao nodded his head, "Find inspiration, dig something out, the three of us, no matter who has any ideas or discoveries, we will discuss them at any time, and conduct cooperative research if necessary, otherwise we will Freedom to explore."

"Got it." Lin Yujing got up immediately, "All the way!"

Du Songtao smiled and waved his hands: "Remember to get off work at six o'clock, don't make me rush."

Speaking of this, Lin Yujing was more confident than studying rockets, and her face was full of determination: "I guarantee that every second will be accurate."

Li Zheng shook his head, got up and muttered: "My thinking is not driven by inspiration, I should study data and algorithms."

"It's up to you, just get off work at six o'clock."

"Is seven o'clock okay? Have a meal before leaving."

"No."

"Why are you so strict?"

"It's that strict."

"Why don't you work overtime..."

Li Zheng returned to his work station resentfully.

It was Lin Yujing who greeted him with a face full of comfort.

It seemed to be written on her face - finally someone can cure you!

……

Since working with Du Songtao, the pace of work has obviously changed.

There is no pressure, no deadline, and once in a while anyone who has inspiration can chat with each other, otherwise they will do their own things.

After two weeks like this...

Sure enough, there is no progress!

During this period, Li Zheng also took three days off to go to Hengshui to get a gold medal in biology and came back. The seventh place in the country also created his worst record since he participated in the competition. Even the questions about him are full of regrets Affection.

However, during this process, Li Zheng's determination was not dispelled by Du Songtao's work style. He still insisted on giving full play to his limited strengths, hoping to use mathematics to find something in the test data.

If it wasn't for confidentiality requirements, he would have taken the mathematical model to ask people like him for advice.

During this process, he also tried to cooperate with people from the Eleventh Institute again, but the focus of the other party's work had already shifted, and he was already too busy with the matter at hand, so it was unlikely that he would devote more energy to Li Zheng's project.

Unlike the tepidness of the "Airborne Division", the opinions of the YF-87 team have been divided into two fierce factions.

First, replace the material and strengthen the entire shafting.

Although the exact cause cannot be diagnosed, since the failure phenomenon is shaft fracture, strengthening this weak link is naturally a feasible way.

The cost of this is a substantial increase in the weight of the engine and a 5% to 15% reduction in the payload of the rocket. Although we are not sure that the problem can be solved 100%, this solution is more intuitive and fast. It can use the factory's production capacity before the start of 927 construction, and it will be completed before the end of the year. test drive.

Second, redesign the entire engine.

As Du Songtao said, a launch vehicle is a complex and sophisticated project.

In many cases, the cost of finding and correcting the fault is far higher than the cost of redesigning from scratch.

If you can't make a thorough improvement in a short period of time, then push back and start over.

This kind of inexplicable low-probability failure cannot happen twice in a row.

就好比在1—100中随机掷出一个数字，1—98都代表成功发射，99和100代表出现故障。

The first time, very unlucky, I got 99.

Then do it again, it is impossible to be unlucky in a row.

The advantage of this plan is that it is more likely to eradicate the disease, and it opens up room for Huang Er's long-term development.

The disadvantage is also obvious, redesigning the engine will not be completed within a year, adopting this plan is equivalent to publicly declaring that Huang Er will give way to the 927.

The matter of China's large hydrogen-oxygen engine is really a long-term plan.

These two plans were naturally mentioned on Zhao Zhenhua's desk.

At this time, Zhao Zhenhua had newly dyed his hair, and all the gray hair was gone.

But under the contrast of this black hair, his face is even older.

"Mingyue... have you never experienced anything in the [-]th Institute... can you not pass this hurdle?" Zhao Zhenhua clutched at the report, his eyes were a little absent-minded, "reducing such a large payload, the meaning of Huang Er is still Does it exist? Isn’t the purpose of using hydrogen and oxygen to pursue a more extreme load? This is equivalent to a person who actively reduces his weight in order to run faster, but you find that his bones have also become brittle, so you go to him What's the point of having two layers of steel plates on the legs?"

"Prove that he can still run." Zhu Mingyue nodded heavily, "Run first, don't fall down, and then seize the time to study the problem."

"Then, haven't we become the sinners who delayed the development of spaceflight?" Zhao Zhenhua weakly raised the report, stared at Zhu Mingyue and said, "Use such a foolish plan to win more resources, tinker and repair, and in a short time It's possible to protect yourself, but I can't say this thing is stronger than 927."

"Then there is only another solution." Zhu Mingyue sighed, "Abandon the present and redesign."

"Alas..." Zhao Zhenhua put down the report, leaned on the back of the chair, and stared at the sky for a long time, "How is Du Songtao's research going?"

"Several ideas have been put forward, but there is a lack of effective evidence and it is difficult to carry out research. Even if there is effective evidence, it may be difficult to find a solution in a short time."

"No, this is not Li Zheng's style..." Zhao Zhenhua straightened up again, "Has Li Zheng made any progress?"

"As far as I know, he is still focusing on data and algorithms, but his ability may have been tapped to the limit." Zhu Mingyue shook his head and said, "He proposed to share data and cooperate with the laboratory of Harbin Institute of Technology, but it is of great importance. Not approved."

"Why?" Zhao Zhenhua stared, "Didn't I say to cooperate as much as possible?"

"Secretary... I... I said something offensive..." Zhu Mingyue struggled and said, "I hope you will be more sober... Now that this is the situation, we will risk leaking the secret... do this... do this It’s not wise to make things look ridiculous to the outside world.”

"Okay, I got it." Zhao Zhenhua raised his arm and said, "Let him apply, instead of going through the troubleshooting channel of your Sixth Academy, go through the scientific research cooperation channel. Bring it over, and I will approve it."

"Secretary..." Zhu Mingyue wanted to cry, "Someone has already said...that you have mental problems...you actually sent two..."

"Let them talk!" Zhao Zhenhua said angrily, "If we can afford to hire top data analysts, I'll count on two fucking middle school students?! Such a project is not allowed to cooperate with data analysis companies, what do you want me to do? ?! There is someone who can afford to find Harbin Institute of Technology to cooperate with me. I am already very excited. The times are changing, Mingyue, we must embrace these new technologies. If we cannot hire top talents, then people like Li Zheng are the biggest Bodhisattva. He messed with him, and didn’t take up your resources, so if you cooperate with Harbin Institute of Technology, you’re afraid of an egg!”

"…………"

After a long silence, Zhao Zhenhua straightened his hair to calm himself down.

"927 has entered the design stage..."

"Lao Liang's eyes are so fucking poisonous. With Shen Tinglan around, this process won't take too long..."

"I'm sorry, Mingyue, it is indeed possible to temporarily overcome the current difficulties by playing the steel plate, but this is to hide the truth for my own benefit. If I use this plan to fool the leader to hide the truth, I will be really crazy."

"I admit that sending Li Zheng is a gamble."

"But the bets I can make are really limited."

"If they scold me, they can scold me. Anyway, I owe a lot of scolding in my life. It's not a loss to be scolded for a few years later."

"I see." Zhu Mingyue nodded, "I'll help Li Zheng draft the report when I get back."

"Thanks for your hard work. This matter is on my shoulders. You don't have to be responsible for the scientific research cooperation channel." Zhao Zhenhua continued, "At this stage, the road of making steel plates cannot be followed, and the plan from the beginning is too late. We can only hurry up and continue. Finding the root cause of the disease, of course, this is not indefinite, at the latest in December, the factory will be mobilized for 12, if the root cause of the disease cannot be found by then, you can start all over again..."

"It's...'us', let's start over together." Zhu Mingyue swallowed.

"Hehe." Zhao Zhenhua smiled, "Don't worry, I will be gone by then."

……

That night, Li Zheng secretly broke the rules.

He didn't get off work at 6 o'clock.

Instead, I huddled in the corner of the restaurant and worked secretly until 9 o'clock, still very excited.

The cooperation with Harbin Institute of Technology has been approved, and it must be exciting to cooperate with the strongest domestic laboratory in the field of engineering computing.

For this reason, he has to race against time to prepare a meeting ceremony to fully express his limited achievements during this period, reduce the understanding cost of Harbin Institute of Technology, and conduct in-depth research as soon as possible.

During this period of time, Du Songtao and Lin Yujing were of course not idle, but they were looking for inspiration from the field of mechanical engineering, which was not their specialty, and even if they put forward some ideas, it was difficult to continue.

Of course, they didn't have such a strong sense of purpose as Li Zheng, and coming here was just a venture capital investment.

Between the keys and the books, a voice came.

"Hi……"

"Let's go now..." Li Zheng thought that the restaurant was about to close, so he raised his hand, "5 minutes."

"It's me..." A person "thumped" and sat next to him, "Are you forgetting?"

Li Zheng turned his head, only to realize that it was the long-cut brother who queued up to enter the office earlier.

"Teacher Liu Rui..." Li Zheng put down what he was doing for the time being, "What's the matter?"

"We have some achievements here, but we can't find anything... I think you are also working on this." Liu Rui said and showed his computer, "I mainly study the latest three test drive data, here... ...you see... a synthesis of 176 suspect frequency curves..."

Li Zheng stared.

For these experimental data curves, he has seen tens of thousands of times.

If ten fat orange cats were placed in front of ordinary people, it would be difficult for him to tell the difference.

But if a person has raised tens of thousands of orange cats since childhood, then this person may be able to identify each of them, call each cat's name, and describe their kinship.

The current Li Zheng is undoubtedly a super cat breeder.

Although it is impossible to describe intellectually, intuitively, he can feel the abnormality of these curves, just like a person can distinguish the patterns, calls, and even the smells of his own orange cat and wild orange cat.

"It's interesting..." Li Zheng said tastefully, "How did you find out these curves? What software? What algorithm?"

"Ah, none of those..." Big Cun Tou rubbed his head, "Human eyes, handmade, picked out one by one..."

"?!?" Li Zheng was shocked.

Even if it is only the last three test data, the content contained is quite terrifying.

Take a less apt example.

Suppose there is a novel of 110 million words, stored as a TXT file, about 2MB.

Your task is to find the typos in it.

But you can't read text, only binary 0s and 1s.

So, you expand this TXT file in binary form.

2MB, or two megabytes.

16777216 bits.

A bit, which represents a binary number, 0, or [-].
