I really don't want to lie down and win

Fortunately, Xu Mang knew that the axioms of fluid mechanics were the laws of conservation, and the laws of conservation were mass conservation, momentum conservation, and energy conservation. These were all in the category of classical mechanics, from which they were modified by quantum mechanics and relativity.

Anyway...no problem.

"Hey?"

"Hey, what are you doing!" Yang Xiaoman's growling voice reached Xu Mang's ears, "Where did you go crazy? What time is it? Have you ordered takeout yet? I just woke up and found that there is no one in the dormitory. "

Ugh?

Whoops...it's already eleven o'clock?

Xu Mang said awkwardly: "Then what... I'm in the lab, you can book it for me now, I'm not free anyway."

Yang Xiaoman: ￣︿￣

So angry!

This guy really deserves a beating.

It stands to reason that a person with such high attainments in academics is so neglected in daily life?

"Hurry up and come back!"

"Oh..."

...

At lunch, Xu Mang told Yang Xiaoman what he thought, but she scolded him angrily, but Xiaoman's curses were a bit weak, they were all idiots, idiots, bastards and the like. To put it bluntly, this is a compliment.

"idiot!"

"Can you show some face?" Yang Xiaoman said angrily: "Is it crazy to think about money? Exploitation also has a bottom, right?"

"No!" Xu Mang felt a little wronged, and said nonchalantly: "Few people know how to use this function, but only for those who need it. Don't buy and install it if you don't want it. This is a relatively free software. ..”

"I don't get a penny of this money, it's all in the account of the charity fund, and this account is managed by my uncle, it's earmarked for its own use, and no one can tamper with it," Xu Mang said.

"cut!"

"Anyway, I don't allow it!" Yang Xiaoman raised his head, and said firmly: "You have to know who you are, and you are not allowed to be so willful in the future. If someone catches you, even if you have a thousand mouths, It’s all unclear.”

Xu Mang babbled, and said secretly, "You don't..."

"Shut up!" Yang Xiaoman's pretty face flushed, and she gave Xu Mang a look: "Big idiot!"

Regarding the charging issue, Xu Mang finally chose to compromise on the surface under Yang Xiaoman's threat of blowing it up.

in the afternoon,

Xu Mang returned to the laboratory and began to conduct an in-depth dissection of fluid dynamics. It was not until Xiaoman called at five o'clock that Xu Mang completed this part of the research. Of course, he needed to have a blast at night, otherwise he would brag in front of Liu Zhuo. , it's a bit embarrassing that it can't be achieved.

night,

It always comes so suddenly.

After Xu Mang tried his best to lull Xiaoman to sleep, he walked out cautiously, sneaked into the building of the computer department, took out a pair of hydraulic pliers from his backpack, and wiped it...the door lock was cut off, and then he He started his old business.

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

Connect to the database,

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

The next day,

Liu Zhuo came to Xu Mang's laboratory. He had to recalculate yesterday's calculation several times to reconfirm its accuracy. After all, Xu Mang's request was [-]% correct, so Liu Zhuo would not take it lightly. Count as many times as you can.

after an hour,

I counted about three times, and found nothing wrong, so I let out a long breath.

"Hey?"

"Liu Zhuo!" The caller was Lin Wanwan, and she asked nervously, "Can you get through to Professor Xu?"

"what?"

"What's wrong?" Liu Zhuo asked curiously.

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

What the hell!

really did it?

Liu Zhuo was stunned for a moment, but quickly returned to normal, and said calmly: "Oh... then update it, I thought it was a big deal, the update is not quite normal."

"It's not normal at all!"

"The entire material department is directly fried, understand?!" Lin Wanwan said: "Professor Xu actually charged nine yuan and nine cents for the installation package, saying that this is an unplanned function for some special groups of people. Isn't this nonsense!"

Liu Zhuo knew this would happen a long time ago, but he never expected that everyone's reaction would be so intense.

"That..."

"Then have you paid?" Liu Zhuo asked curiously.

"I bought it without hesitation." Lin Wanwan said helplessly: "Now that I think about it, I feel that Professor Xu is abominable. Can't I order a price of nine hundred and ninety-nine yuan? I just set a price of nine yuan and nine cents. This number is simply a reminder !"

"But that's not the point..." Lin Wanwan said, "Professor Xu actually wrote the original price [-] on the side... After I saw the [-]% discount, I couldn't control my hand."

"Where are the others?" Liu Zhuo asked, "Did anyone else buy it?"

"I bought them all!"

"I bought it because it was so cheap, but when I bought it, I found that I couldn't use this function." Lin Wanwan said, "Is this Professor Xu sent here by the capital world? A bad guy lurking around us?"

Liu Zhuo: 囧

indeed,

Professor Xu is simply a genius in the capital world!

Precisely control the part of people's curiosity and greed, and use the magic numbers like nine dollars and nine cents and two discounts to conquer all men, women and children.

Just shy of double digits, but it's single digits!

Are you angry?
