For Liu Zhuo's request, Xu Mang will naturally go all out to complete it, but... After all, not many people use the fluid dynamics analysis function, and it is embarrassing that no one uses it after working hard to get it out by themselves.

"Liu Zhuo?"

"Have any of your materials students bought software?" asked Xu Mang.

Liu Zhuo nodded and said seriously: "I bought it, this must be bought, although Professor Xu, your price is a bit high, and many students can't afford it, but... The school is very good to our material department, and if students buy software, there will be a subsidy of 500 yuan. ”

"Therefore, the students of the Department of Materials of Fudan University only need to pay 199 yuan to buy the software, and the other 500 yuan will be given by the school. Liu Zhuo said: "The price of one hundred and ninety-nine is acceptable, and G is fat for a game money." ”

Yes?

And such a routine?

Xu Mang was stunned for a moment, and decided on the spot to charge a sum of money for each update, and price it according to the content of the update, such as this hydrodynamics analysis function, it is not too much to charge nine yuan and nine cents, right? Anyway, it is not you who pay for it.

In addition, this money is not in my pocket, to the account of the Scholarship Charity Foundation, this account is managed by the writer's father-in-law, and the funds are earmarked...

"Liu Zhuo?"

"Do you think... Quantum analysis software, with the function of fluid dynamics analysis, charges nine dollars and nine cents for the update fee... Is it too much?" Xu Mang asked embarrassedly: "You answer me honestly, can't you go too far?"

Liu Zhuo looked at Xu Mang with a frightened expression and said angrily: "Professor Xu! You are too much! How can you be so greedy? Where is your conscience?"

This Nima...

Why are you so excited all of a sudden?

Xu Mang shrank his head and said cautiously: "Liu Zhuo... I would like to talk to you about poverty, which is one of the most acute social problems in the world today, and poverty is divided into absolute and relative, with income as the decisive factor and the relative inability to meet the most basic needs of life under local conditions. ”

"Of course... What I can solve is the education problem of poor students, and my ability is limited, I can only solve a very small part, take Fuda as an example, how many poor children give up the opportunity to study because of money, and go to work part-time. ”

"The problem is so serious, what's wrong with me charging nine yuan and nine cents?" Xu Mang said with a serious face: "It's not spent on me... And the school will give it, what are you panicking about... Isn't that right?"

Liu Zhuo was speechless for a while, as if he had been analyzed by Professor Xu, and there was some truth.

"That's it!" Xu Mang said with a smile: "The price is nine yuan and nine cents, this belongs to the category of the installation package, it doesn't matter if you buy it or not, it doesn't affect the use of the original software if you don't buy it, the development of this installation package is for special people." ”

Liu Zhuo nodded and said seriously: "It is true that there are not many people who use the function of fluid dynamics analysis, but Professor Xu... You'd better talk to the principal, or I'm afraid something big will happen if you mess around like this. ”

"Oh. ”

"Go and say it in the afternoon. Xu Mang nodded: "Come back tomorrow afternoon, don't talk to anyone about today's events, you know?"

"Understood!"

After Liu Zhuo left, Xu Mang sat on the recliner and began to think about the function of hydrodynamic analysis.

Fortunately, Xu Mang knew that the axiom of fluid mechanics is the conservation law, and the conservation law is the conservation of mass, momentum and energy, which are all categories of classical mechanics, from which quantum mechanics and relativity have been modified.

In a word... Nothing was a problem.

"Hello?"

"Hey, what, hey!" Yang Xiaoman's roaring voice reached Xu Mang's ears, "Where did you die of a nervous disorder? What time is it? Have you ordered takeout? Old lady, I just woke up and found that there was no one in the dormitory. ”

Alas?

Oops... It's eleven o'clock?

Xu Mang said embarrassedly: "What's that... I'm in the lab, you can order it for me now, I'm not available anyway. ”

Yang Xiaoman: (* ̄〈 ̄)

It's so angry!

This guy really owes a beating.

It stands to reason that a person with such a high level of academic attainment, how can he be lost in his daily life?

"Hurry up and get back!"

"Oh..."

...

At lunchtime, Xu Mang told Yang Xiaoman his thoughts, and was scolded by her angrily, but Xiaoman's scolding is a little weak, they are all stupid, idiots, bastards and the like, which is a compliment for Xu Mang.

"Idiot!"

"Can you make a face?" Yang Xiaoman said angrily: "It's crazy to think about money, isn't it?

"No!" Xu Mang felt a little aggrieved, and said no-no: "This function is rarely used by people, just for those who need it, don't buy and install it if you don't want it, this is a relatively free software.."

"I can't get a cent of this money, it's all to the account of the charity fund, and this account is managed by my uncle, and the funds are earmarked, and no one can touch it. Xu Mang said.

"Cut!"

"Anyway, this palace is not allowed!" Yang Xiaoman raised his head and said with a firm face: "You have to know what your identity is, you are not allowed to be so willful in the future, if you are caught, even if you have a thousand mouths, you can't tell it clearly." ”

Xu Manba pursed his mouth and said secretly: "You don't do it every night..."

"Shut up!" Yang Xiaoman's face turned red and glared at Xu Mang: "Big idiot!"

Regarding the issue of fees, in the end, under the threat of Yang Xiaoman's pinching, Xu Mang chose to compromise on the surface, and there was no way... Everyone is going to pinch it up, take a step back and open the sky.

Afternoon

Xu Mang returned to the laboratory and began to conduct a deep dissection of fluid dynamics, until Xiao Man called at five o'clock, Xu Mang completed this part of the research, of course, he needed to burst his liver at night, otherwise it would be a bit embarrassing to brag in front of Liu Zhuo.

night

It always comes so suddenly.

After Xu Mang tried his best to lull Xiao Man to sleep, he cautiously walked out, sneaked to the building of the computer department, took out a hydraulic vice from his backpack, and clicked... The door lock was cut off, and the old business was done.

As the manager of the database, Xu Mang naturally has the key to the laboratory.

connecting to the database,

Turn on the beast mode, and the happy update journey is officially launched.

Following

Liu Zhuo came to Xu Mang's laboratory, he wanted to recalculate yesterday's calculation several times to reconfirm its accuracy several times, after all, Xu Mang's requirements were 100% correct, Liu Zhuo naturally would not take it lightly, and he would try to calculate as many times as he could.

An hour later,

I counted it about three times, and I didn't find any problems, so I took a long breath.

"Hello?"

"Liu Zhuo!" The caller was Lin Wanwan, and at this time she asked nervously, "Can you get through Professor Xu's phone?"

"Huh?"

"What's wrong?" asked Liu Zhuo with a curious expression.

"The quantum analysis software has been updated!" Lin Wanwan said angrily: "According to the update instructions above, it seems that some fluid dynamics analysis function has been updated. ”

it!

Did it really happen?

Liu Zhuo was stunned for a moment, but quickly returned to normal, and said indifferently: "Oh... Then update, I thought it was a big thing, and the update was not quite normal. ”

"Not normal at all!"

"The whole material department is directly fried in the pan, do you understand?!" Lin Wanwan said: "Professor Xu actually charges nine yuan and nine cents for the installation package, saying that this is an unplanned function for some special people to use, isn't this nonsense!"

Liu Zhuo had known that such a situation would occur, but he never expected everyone's reaction to be so fierce.

"That..."

"Then did you pay for it?" asked Liu Zhuo curiously.

"Didn't hesitate to buy it. Lin Wanwan said helplessly: "Now that I think about it, Professor Xu is very hateful, can't he set a nine hundred and ninety-nine yuan?

"But that's not the point..."Lin Wanwan said: "Professor Xu actually wrote the original price of fifty on the side... When I saw the two folds, I couldn't control my hand. ”

"What about the others?" Liu Zhuo asked, "Did anyone else buy it?"

"Bought them all!"

"I bought it because it was so cheap, but when I bought it, I found that I didn't need this feature. Lin Wanwan said: "Is this Professor Xu a gap sent by the capital world?

Liu Zhuo: Wow

truly

Professor Xu is simply a genius in the world of capital!

Accurately control the curious and greedy parts of people, and use magic numbers such as nine pieces and nine cents and two folds to conquer all men, women and children.

It's just a little bit to double digits, but it's a single digit!

Angry or not?

By the way, I will force the obsessive-compulsive person to death, if you don't buy it, will you?

meanwhile

Xu Mang, who was sleeping, was bombarded indiscriminately by the principal's phone.

"Xu Mang!"

"You kid get here for me!" the headmaster growled.

“...”

Xu Mang looked at the interrupted call interface and was speechless for a while.

"Who?"

"Early in the morning... Don't let people sleep?" Yang Xiaoman lay in Xu Mang's arms, and said angrily: "Continue to sleep... Ignore it. ”

"It's the second grandfather's phone, it seems... Looks like something is looking for me. Xu Mang said helplessly.

"Oh..."

"Go and come back. Yang Xiaoman twisted his body to the side and continued to sleep.

After putting on his clothes and pants, Xu Mang went to the principal's office.

To the door,

Xu Mang thought about how to deal with it, and finally chose to respond to all changes with no change.

"Second grandfather?"

"Hehe..." Xu Mang came to the office with a smile and said to the principal with a black line: "I see that you have a bad complexion, are you experiencing any trouble?"

"I said Xu Mang?"

"How long has it been since the turmoil about supporting software, why have you started to be dishonest again?" The principal said helplessly: "What does the nine-yuan nine-cent fee installation package mean? Are you planning to use this software to make 100 million?"

Xu Mang smiled and nodded: "That's okay!"

"Okay?"

The principal was almost not angry with Xu Mang, and reprimanded Xu Mang: "Yang Jian's family is so rich, why are you staring at the mosquito legs?"

"All this money is used for charity. Xu Mang said: "I'll calculate for you, the Scholarship Charity Foundation has used almost all the money in the colleges and universities in the magic capital, what about the next year?

"Second grandfather, I'm under a lot of pressure. Xu Mang sighed: "And do you think that all this money goes to my pocket? In fact, it is all in the account of the foundation, and my father-in-law takes care of himself, and I can't spend a dime." ”

“...”

"Discuss it with me next time you do something like this. The headmaster glared for a moment and waved his hand, "Go back." ”

Passed,

Safe and sound,

Xu Mang left the office with a smile.

Come to the lab,

Xu Mang saw that Liu Zhuo was also there, so he smiled and said, "Why is it so early today?"

"Professor Xu. ”

"I'm here to do the math. Liu Zhuo said: "Professor Xu... You... The headmaster shouldn't have been looking for you yet, has he?"

"Yes. ”

"I just got back from the principal's office. Xu Mang said with a smile: "What? Do you think I have been trained? Do you think I have been trained?"

This...

Is this all right?

Liu Zhuo felt a little surprised.

Followed by

The two of them began the next work, Xu Mang revised the performance indicators, and Liu Zhuo learned the tutorial on how to use the latest features.

Just over an hour,

Xu Mang found his fatal mistake, due to the different thermal expansion coefficients of insulators and metals, the interfacial thermal stress from room temperature to liquid nitrogen temperature will affect the air tightness.

"Professor Xu?"

"What's wrong with you?" Liu Zhuo saw Xu Mang's desperate look and asked curiously, "It seems to be very uncomfortable." ”
