A few hours of driving was a quick ride, and I was back in Ark City in a blink of an eye.

Gu Yu asked very gentlemanly: "Yiyi, do you want to send you to your sister first?"

Ma Yiyi: "You can go back by yourself, leave me alone." It's a big deal, I'll sit at your house for a while, and I'll take a taxi back to my sister in the evening. ”

Li Shuangye was beside him, and he didn't say anything, only to support his brother's uprightness.

has already shouted with his husband and wife, and they are so respectful.

Gu Yuyan listened and went straight home.

The Gu family's house is not big, but in a small high-rise building near Binjiang New Town in the east of the city, a 90-square-meter elevator apartment.

It's not that you can't afford to change to a bigger house, but because you have lived with your mother and Gu Yu all these years, so the 90 square meters of the three-bedroom and one living room are enough, no matter how big it is, it is a waste, but it is a trouble to clean.

As it is now, my mother is so busy with work that she is too lazy to clean often. Generally, every half a month, call the hourly workers of the housekeeping company to clean up.

The house price on the Blue Hole Star in 99 years is similar to that of 05/06 on the earth, and the Ark City has risen a lot in the first two years, but it seems that it can rise a lot in the future.

At present, the Gu family's apartment, if it is sold on the market, is estimated to be worth seven or eight hundred thousand.

The best location in the downtown business district is only 10,000 yuan a square meter. Of course, you can't choose a scenic spot or a lake-view house by the West Lake, that thing is a pit, and there is no cap.

As for the new development zone in the suburbs, there are still 3,000 square meters of real estate.

Gu Play has spare money and has a girlfriend. And with the complete reconciliation between her mother and Aunt Li, her sister Li Shuangye may often come to borrow it in the future.

So he also began to think about dividing some money to improve the conditions of his family.

He has all the money on hand, and there are 1.3 million US dollars, which is just over 10 million yuan when converted into RMB, and spending one or two percent will not affect his next career.

Thinking about things in his heart, the elevator had already reached the floor, Gu Yu pushed open the door, and greeted him before he saw anyone:

"Mom,We're back.,Futaba is also here.,I'll introduce you-uh,Actually, it's not called an introduction.,The last time you met.,Yiyi.,It's my new girlfriend.。 ”

Ye Di was cooking lunch, wearing an apron, and came over in surprise when he heard that he was holding a spatula. Obviously, it was because Gu Wan's secrecy was too good, so until a few minutes ago, only his sister Futaba knew that he had a girlfriend.

"You...... You don't tell me in advance, I'll get a few more dishes. Ye Di complained for a while.

Ma Yiyi hurriedly said hello: "Hello Auntie, don't bother, I'm just taking a ride back by the way, come and sit, and I will go back to Yongcheng with my sister for the New Year the day after tomorrow." ”

"This kid, how can he come to the door casually for the first time? Ye Di secretly complained in his heart, but he didn't say it.

She has already seen that her son and this Ma Yiyi are emotional idiots, and they are not even serious at all about bringing them home to meet their parents.

For other people who can play, which one should not play all the tricks first, and then consider meeting the parents, but also make solemn arrangements.

But after just complaining a little in his heart, Ye Di also accepted this setting. After all, she doesn't want her daughter-in-law to be very capable and sophisticated.

As soon as Ye Di finished his polite manners, Gu Yu heard another human voice coming from the back room, and a series of footsteps came from far and near.

"Are there any guests at home?" Gu Yu subconsciously asked his mother.

Ye Di: "Your brother, he knows that you came back today and came to block you, and he has business matters to discuss with you." ”

As soon as Ye Di finished speaking, Zhou Xuan appeared and said a few polite words to the three of them.

Then Zhou Xuan also took advantage of Gu Play to wash his hands alone, and the girl was not around, and encouraged:

"You kid can, I thought you were still a wood, come back during the New Year, and take you to the entertainment to see it. Now that I have younger siblings, I can't persuade you to be sorry for others, so let's owe it. ”

Originally, Zhou Xuan belonged to the kind of social person who was very playful and scumbag clearly, if he wasn't afraid of delaying Gu to play the college entrance examination, he would have taken him to the big sword half a year ago to open his eyes.

What's more, now that Gu Play is developed, Zhou Xuan often asks for him, so he naturally has to find ways to arrange it clearly.

Even if it's a cousin, as long as it involves money and business, the benefits are still indispensable.

"he~tui~" Gu Yu took a sip teasingly, of course there was no malice, just a joke between brothers,

"With your temper of not seeing rabbits and not spreading eagles, if you don't have any business to beg me, will you want to arrange a woman for me? ”

Zhou Xuan: "Damn, is it a shame for you to say this? Heaven and earth conscience, if it weren't for the fear of delaying your college entrance examination and being wild, I would have arranged you clearly last year, and you didn't have anything at that time, what do you think I would do to you?"

Gu joked and smacked: "You can't afford to make jokes." ”

Zhou Xuan scolded with a smile: "Then I'll say it directly, in fact, it's not a big deal." First of all, you may not know that we have officially signed a procurement contract with the GPS International Cooperation Preparatory Committee for 3 cesium atomic clocks, and the other party has already called.

"It's only 3 seats, what is there to guess, just say it. "Gu Yu is not interested at all.

Zhou Xuan didn't sell it, and felt that the boss was boring: "You are boring! A total of 6.5 million US dollars, which is 500,000 yuan higher than the total price originally booked!

At present, the first three sets are ordered, one for the GPS No. 2 test star and one for the No. 3 test star, and one is left at the NASA main base in Houston as a reference to carry out some other scientific experiments.

However, after the successful launch of the No. 3 test satellite at the end of the year at the latest, as long as we do not find any flaws in our cesium atomic clock, the follow-up will be a single order of 25 units, a one-time contract of 50 million US dollars!

I won't hide it from you, although the property rights of the technology belong to the company, as long as everything goes well, I personally will get a benefit of hundreds of thousands of dollars, which is more than enough. ”

Gu Play heard a different concern from the other party's boasting: "When it is sold in batches, why does the unit price drop back? Isn't it 6.5 million for 3 units and close to 220 for one during trial production, and the mass production of the oceanic guy is only willing to pay 2 million?"

Zhou Xuan smiled flatteringly: "Actually, the 650 of the first order is not all about the money from selling equipment, but also about technical support." At that time, if it weren't for you or Yuan Xiong, you might have to go on a business trip to Oceania for a while.

After all, to install the atomic clock on the satellite, it is still necessary to provide technical support for the follow-up links, and the satellite manufacturer will definitely want you to lose weight.

I also just learned some common sense in the circle - the satellite launch weight increases by one gram, and the total budget may be three or four thousand dollars more expensive if all the upstream and downstream links are combined.

You can easily shoot an atomic clock more than ten kilograms into the sky, and the cost of shooting it into the sky is several times more expensive than the clock itself. Satellite integrators certainly want you to keep the weight as low as possible. ”

What's more, if the weight of the atomic clock increases by one gram, the total weight of the satellite will definitely increase by more than one gram, because the structural design of the satellite also needs to set aside some supporting reinforcements. The end result is about 1.3 to 1.4 grams of total weight gain.

This means that for every gram of weight of the cesium atomic clock, the cost of each launch will be reduced by at least five or six thousand dollars.

The entire GPS project is 30 satellites, which means "saving nearly $200,000 per gram per unit".

Gu Yu calculated this account in his heart and was silent.

Zhou Xuan didn't know what he was thinking, and hurriedly added benefits and temptations: "Of course, I won't let you or Professor Yuan go in vain." We collected 500,000 yuan in technical service fees and allocated at least 200,000 dollars for travel expenses.

You can spend whatever you want, and even bring an assistant to wave it as much as you want, and the embassy of the other party will do everything to help you get your passport and visa abroad. The US side will definitely have another incentive at that time, and this is all in two words, and you will not be allowed to suffer in vain. ”

Gu Yu couldn't help but laugh: "Heh, how generous, on the basis of the current basis, I will reduce the weight of the atomic clock by one gram, and the launch funds they save from the entire project will be 200,000 US dollars."

Spending 200,000 yuan to invite us to go abroad to eat, drink, and have fun is also called a thing? This is just the cost of dozens of satellites, each light 1 gram. ”

PS: To revise yesterday's words, this book will be on the shelves next Friday, October 18th.

The results are really not good, and everyone doesn't chase more, so it has been made clear that there is no Sanjiang without strong push.

I can only comfort myself now, "Many people don't chase it after a few glances after collecting it, because physics is too hardcore, I can't understand it, and I don't want to read it"

So, my last hope is that "the people who don't want to see it have already abandoned it, but they haven't canceled their collections yet." Those who stay and are still chasing are deeply consistent with this book, and the conversion rate of genuine is very high."

See you on October 18th, take a gamble.
