When Zheng Jianguo's face was full of joy, Valentin Levin, who had also put down the phone, also looked happy: "Okay, Zheng Jianguo agreed, and the paper doesn't have to be sent to him, Bart went to stuff his mailbox, didn't you say that he was very arrogant?"

"From the process of convincing him, I feel that I have gullible some people's nonsense~"

The man with glasses named Bart tilted his head, and even if he didn't refuse, he accepted the task, seeing his appearance, Valentine's eyes flashed a few times on his face, and he quickly spoke: "You are not allowed to contact him, just leave him the address you want to mail, he is currently the most authoritative reviewer of our magazine, of course, I mean in terms of Helicobacter——"

"And solid state physics, and his discovery of atomic-scale graphite layers is also subversive—"

Bart licked his tongue and said, and then remembered that if the helicopter in gastrointestinal disease had something to do with his own, then what he said couldn't be beaten together, so he blinked and said: "It's a pity that it has little to do with us, I don't know if Zheng Jianguo has conducted in-depth research on Helicobacterium?"

"Maybe he's busy working on atomic-scale graphite layers?"

Valentin Levin shook his head and said, and the expressions of the people present suddenly changed, and they felt that Zheng Jianguo was also hard enough, and the research content on both sides was groundbreaking discoveries.

Of course, Valentin Levin didn't know that Zheng Jianguo was preparing for the 2nd stage of the medical license, for this level, he was a head cantilever in addition to eating, drinking, and Lazar is endorsement, until Zhao Liangliang's voice appeared on the phone, he remembered that there was something he didn't do: "Sorry, I forgot to call you, you can go-"

"I guess you're busy and forgetful, remember to give me a date back after booking the ticket, and pay attention to rest, hang up. ”

Zhao Liangliang hung up the phone after telling him, Zheng Jianguo pinched his eyebrows a little tightly, knowing that he had gone a little too far recently, the phone he put down jumped again, and a familiar voice came after picking it up again: "Jianguo, I'm Yang Na." ”

"Hi Hani, there's bad news-"

Yang Na in the microphone didn't wait for Zheng Jianguo to speak, so she continued to talk to herself: "After Sister Fan wanted to add a bed to British Space last time, the other party said that after calculation and confirmation, you asked to increase the fuel load to 160 tons, and if you count the 78.7 tons of the plane's own weight, this figure will reach 238.7 tons!"

The existing 4 Olympus 593Mk610 turbojet engines provide a maximum take-off weight of only 186 tons, which means that according to your requirements, the cabin area can be reduced to modify the fuel tank, but there are also problems such as insufficient thrust of the engine and the strength of the body after increasing the fuel load. ”

"Well, if they ask a problem, then they will also give suggestions for improvement, right?"

Zheng Jianguo dragged the phone to the coffee machine and said, and Yang Na in the microphone continued to speak: "Unless you change your mind, the advice given by the aerospace company is to replace the Olympus 593 improved engine and replace the existing alloy steel structure with titanium alloy."

This engine eliminates the afterburner chamber to increase the compressor diameter, and adds a low-pressure turbine stage instead and a noise reduction device, which will reduce noise by about a fifth and increase engine efficiency by 25%.

That is, from the existing maximum take-off weight of 186 tons to 232.5 tons, and then replace the existing alloy steel with titanium alloy, they say that the weight can be reduced by 15 percent, that is, the original 78.7 tons of weight can be reduced to about 67 tons.

This will meet your requirement of 160 tons of fuel, and in addition, reduce the noise caused by the engine by one-fifth, although this noise is still relatively high in the aircraft, but it is about the same as other large aircraft.

And due to the increase in fuel load, the weight of the aircraft increases, and the number of tires needs to be increased to cope with the corresponding strength, and the increased number of tires can reduce the safety hazards to the aircraft when a single tire is damaged——"

"So, how much do you need to add?"

The voice in the microphone stopped, Zheng Jianguo also asked, and soon Yang Na's voice came: "It needs to be increased by 18 million US dollars, of course, it can be included in the final payment, that is, this money will be paid after delivery, I confirmed with Sister Fan before, if you agree, we can divide this money equally, after all, it is almost far from the capital and from Hong Kong Island——"

"People are knives and I am fish and meat, now there is only such a family selling, refusing or something is a joke, then the three of us will divide it equally, of course, the extortion point is still the extortion point, let them do a good job of tire improvement and fuel tank protection, and the noise decibels in the cabin cannot be higher than 60——"

There is not much place to negotiate in terms of price, after all, only Concorde aircraft in the world can meet Zheng Jianguo's requirements, and it is not a wise behavior to bargain in this case, after all, this is not clothes, pants, shoes and socks, but an aircraft to protect the safety of his whole family: "It's okay to slow down the modification time." ”

"They didn't say it was about the time of the modification—"

Yang Na's voice in the microphone paused a little, and then sounded again: "Now it seems that they had this suggestion when they took our modification order, the aircraft engine can be purchased from the manufacturer, but it is not normal to have a plan to replace the strength structure——"

"Maybe people want to produce an improved Concord, just in time for us to catch up. ”

Zheng Jianguo thought about it, it was a good thing for him that people had this plan, after all, even a major change would not delay the delivery period, which would allow him to let his family sit on it earlier, but he didn't know that his guess was extremely close to the truth.

As early as 1976, four months after the Concorde entered commercial service, the ambitious British Aircraft Corporation and Aerospace France proposed a design for the next generation of the Concorde, known as the Concorde B.

It's just that the design of the Concord B is not as exaggerated as Zheng Jianguo's request, only the fuel load and wing area of the original model have been increased, and the engine that is now being marketed to him is the product of this plan, of course, the subsequent increase in fuel prices ended the plan, so the previously purchased spare parts can only be left in the warehouse to eat ashes.

In addition, due to the purchase intention orders of nearly 300 aircraft (4 aircraft were ordered by civil aviation), British Aircraft and French Aerospace purchased a large number of spare parts for the Concorde aircraft at that time, but did not want to build only 20 aircraft due to fuel prices, and this batch of spare parts was not used up until the model was retired.

Of course, Zheng Jianguo didn't know this, and Yang Na was relieved after hearing his request: "Your gold contracts have all been closed, right?"

"I closed the position, but I bought all the oil contracts again, and now I have earned, 100 million. ”

Looking up at the price of oil in the newspaper in front of him, Zheng Jianguo found that it had reached 28.79 cents, so he calculated it according to the calculation method given by Charlie, and then said: "If you close the position now, the principal will be more than 400 million." ”

"You used high leverage?"

Yang Na's voice in the microphone was full of surprise, and Zheng Jianguo also spoke: "Ten times leverage, now I am richer than you-"

"Maybe you'll be bankrupt tomorrow—"

Yang Na's voice came, and Zheng Jianguo then smiled: "Then I have to eat soft rice-"

"Hmph-"

Inexplicably sweetness swelled up in her heart, and Yang Na, who wanted to speak, couldn't help but smile coquettishly: "The beauty you think, I have to squeeze you-"

"What will you use to squeeze me?"

Yang Na's delicate cheeks flashed in front of him, Zheng Jianguo licked his tongue and said rarely, but he didn't expect a familiar voice to suddenly come from the microphone and fly away: "Alas, alas, the world is declining, people's hearts are not ancient, I'm leaving, you two-"

"Sister Fan was here just now!"

Soon Yang Na's coquettish voice came, Zheng Jianguo couldn't help but be a little confused, staring at the microphone for a while, and the voice in the microphone still kept coming: "Hmph, you have also learned badly, are you a playboy who has seen too much?"

"You didn't say that Sister Fan is here, how can I look at those things, the pathology hasn't been memorized yet. ”

Remembering that this young lady said that she had confirmed it with Fan Dailin, Zheng Jianguo thought that it was confirmed on the phone, but he didn't expect the two to be together, so he said, "Are you on Hong Kong Island now?"

"No, Sister Fan came to the capital to escape from marriage. ”

Yang Na's voice was a little strange, and then a sentence came out: "We made an appointment before, and we can't be together until you graduate, so I stayed here and didn't look for you, do you understand?"

"Clearly, you want to focus on your career. ”

Of course, Zheng Jianguo knows that this and Fan Dailin are both small and exquisite, but they are both strong women in the series, otherwise how can they insist on getting a doctorate in medicine from Harvard: "Sister Fan has found her true destiny?"

"It's been a year since the blind date, I originally thought this was about the same, who knew that there was an ex-girlfriend outside who didn't break, of course, this is Sister Fan's own idea, I think that according to your family, it is a donkey egg - surface light. ”

Even if the thrush between lovers made Fan Dailin hear, Yang Na was not disturbed by this little episode to disturb her cheerful mood, after all, the two have been in a relationship for more than half a year, but no one has ever broken through the boundary between friends in words or actions.

Until today, I don't know if Zheng Jianguo didn't wake up or learned too much, so I have a feeling that the relationship is advancing by leaps and bounds: "Opening your mouth and closing your mouth is either stocks or futures, and the family is a little money, probably tens of millions - if you said earlier that you would buy crude oil contracts with ten times leverage, I would have to let him know what stock speculation is." ”

"Futures, this is called futures—"

Hearing someone running to Yang Na chattering, Zheng Jianguo felt as if he saw Lemon beckoning to him, but he remembered that it was Fan Dailin's boyfriend, so he spoke: "You are careful to let Sister Fan hear it, there is a Xi Shi in the eyes of the lover, when this woman is in love, well, she can only see the benefits of the other party." ”

"Oh, you still have research on how women behave when they are in love? Self-taught psychology?"

Yang Na's voice came, Zheng Jianguo knew that there were a lot of bald mouths before, but fortunately, it was the first time that the two of them had communicated in this state, so he said: "You don't know that there are more emotional programs here, this show and that show, I forgot which channel I saw it from, my Helicobacter hasn't been studied yet, how can I study those things - I don't want to be a psychiatrist." ”

"If you become a psychiatrist, then let's pull it down, the one I hate the most is the psychiatrist. ”

Yang Na heard that this goods had the meaning of forgiveness, even if she let go of this: "There are still a few days before the Spring Festival, Sister Fan said that she has not yet spent a real New Year in China, so she decided to go to your house for the New Year. ”

“？？？”

I wanted to drink the coffee in front of me, and when I heard this, Zheng Jianguo couldn't help but blink and put down the coffee, and said, "Are you sure you want to go to my house for the New Year?

"I know that only fiancées who are married and have not yet married can go to their in-laws' house for the New Year. ”

Yang Na's voice was a little low, and Zheng Jianguo took a sip of coffee and said, "I never wanted to invite you, because I was afraid that you would think I was frivolous, that I didn't respect your will, that I didn't consult you, and that I just ignored your man-"

"I know, but you may have learned a little too much and had too many concerns, only if you open your mouth to invite, then I can discuss with you, and if you don't open your mouth to invite, how can you let me say, oh, Zheng Jianguo, I want to go to your house for the New Year?"

Interrupting Zheng Jianguo's words directly, Yang Na quickly said her reasons, and continued without waiting for Zheng Jianguo to speak: "Then you will look down on me and think I am frivolous, right?"

"Okay, I'll call home later—"

confirmed Yang Na's heart, Zheng Jianguo also remembered that it was problematic for him to arrange her to send the third sister before, since he wanted to send off his relatives on behalf of himself on the eighteenth day of the first month, so in Yang Na's position, he had to consider that since he was going to appear in front of the Zheng family, and he appeared as a girlfriend, why didn't he come during the Spring Festival, but waited until the eighteenth day of the first month?

And if you follow Yang Na's proposal to go home for the New Year, you can justifiably wait until Zheng Qiuhua gets married, of course, this sister takes Fan Dailin as a cover, and it can be regarded as a backhand left by Zheng Jianguo's true attitude: "Sister Fan is going." ”

"I might be a little dizzy from learning—"

Zheng Jianguo thought about it, but decided to apologize: "The last time I arranged for you to send the third sister to my home, I felt that something was in my mind, maybe it led away what I was about to say." ”

"I know that I didn't change my clothes for a week in order to study for my doctor's license, and now you're preparing for exams and participating in research in the physics lab, so I don't blame you. ”

Yang Na's voice was a little fluttering, she remembered that she almost collapsed when she faced the pressure of the medical examination, and the pressure of the one she chose was probably much greater than that of her back then, and her tone swelled with deep joy: "After all, you agree now after knowing it, right?"
