The military-industrial scientific research system of the academic master.

Chang Haonan's first New Year after his rebirth passed in such a dull atmosphere.

Originally, he planned to stay at home for the Lantern Festival before returning to school.

But the current situation does not allow him to be offline for such a long time.

After all, the greater the ability, the greater the responsibility.

There are too many places where Chang Haonan's help is needed.

……

On the night of the third grade of junior high school, while the family was watching TV after dinner, the phone suddenly rang.

It was Zhou Li who answered the phone.

"Hello, who is it?"

Chang Haonan didn't pay attention at first. After all, the person who made the call at home was basically either a relative or a colleague looking for Chang Yuanchao or Zhou Li.

No one he knew knew his home number.

However, the mother's next words made Chang Haonan's breath hitch:

"Yes, Chang Haonan is here."

"..."

After more than nine months, this familiar feeling is back!

It smells like working overtime!

Sure enough, after a few seconds, Zhou Li said again:

"Then I'll give him the phone, please wait."

Then she covered the microphone with her hand and looked at Chang Haonan on the sofa:

"Xiao Nan, there is a man named Yi Yuanhe. He said that he is an engineer at Haojing Institute of Aviation Industry 603. He wants to see you if there is something urgent."

Chang Haonan nodded with a complicated expression and stood up to take the phone.

"Master Yi, happy New Year."

"Happy New Year, Comrade Xiao Chang."

Yi Yuanhe's voice on the other end of the phone was also a little embarrassed.

After all, even if calculated based on their working days, the third day of the Lunar New Year is only half of the holiday.

What's more, Chang Haonan is still a student and enjoys the winter vacation at school.

"I'm really sorry that I have to disturb you during the Chinese New Year..."

"Mr. Yi, let's stop seeing each other."

Chang Haonan replied with a wry smile:

"If there was nothing urgent, I guess you wouldn't go to all the trouble to find my home phone number, right?"

He just vaguely remembered that before entering the freshman year, there would be a home phone number when filling out the file.

However, this requires checking the files to find out. In addition, it is still the Spring Festival holiday, and the school's administrative staff should not be at work. It must be quite troublesome to check the files.

"Then thank you Comrade Xiao Chang for your understanding. It is indeed urgent, regarding the anti-icing system and airworthiness certification standards we have done before."

"Well……"

Hearing this, Chang Haonan suddenly had a guess in his mind.

This incident is probably related to the plane crash I saw the day I just returned home——

Because from the perspective of investigation, of course there are many possibilities that could cause the air crash.

But if the ice accumulation problem is really taken as the starting point, the characteristics of the accident are actually very consistent with the situation where the ice thickness on the wing exceeds the threshold during landing, and the anti-icing system does not work properly, causing one wing to lose lift.

Factory 60 and Factory 603, which are currently working on the MA172 in full swing and are preparing to enter this model into the European market, will obviously take this suspected ice damage accident very seriously.

The only thing that made him a little confused was that China was generally a country where ice damage was not serious. The poor record of Yun 8 was simply because the original design was really bad.

Moreover, the MA-60 is still a long way from being finalized, and it has already conducted test flights under four types of ice damage conditions before.

The matter seems to be in no hurry these days.

But in any case, even if MA-60 is not a confidential project, talking about too many technical issues on the phone is obviously not a good choice.

"So, what exactly do you need me to do?"

Chang Haonan went straight to the point.

"The Science and Technology Commission will arrange a flight from Liucheng to Haojing tomorrow. We will discuss it in detail after you come over."

Yi Yuanhe was obviously not prepared to talk too much at this time.

"division……"

Chang Haonan was a little surprised, those three words almost blurted out.

The Science, Technology and Industry Commission is not the leading party in the MA-60 model itself. It allows them to use resources specifically to arrange the aircraft, which shows that there may be more things behind it.

This made the remaining resentment in Chang Haonan's heart turn into curiosity and expectation.

"Okay, then we'll see you tomorrow."

After Chang Haonan finished speaking, he hung up the phone.

"Xiaonan, is...is there something going on at school?"

Zhou Li, who was standing behind her, asked cautiously.

"Ah, yes, there is an emergency at the project, and they asked me to go back tomorrow."

Looking at his mother's expression, Chang Haonan felt a little apologetic in his heart.

After all, this time he returned home after a year, but he only stayed for less than a week.

After Chang Jiayao, who was sitting on the bed just now, heard this, she suddenly jumped out of bed and ran back to the house.

After returning from Chang Haonan, something happened to this little girl. She stayed in her room for a particularly long time.

"I think that's a good thing."

Chang Yuanchao next to him looked at the problem from a different angle:

"Like when I was working in criminal investigation, didn't I often get called away during holidays or in the middle of the night? Now that I'm sitting on the bench as an in-house clerk, I feel at ease."

"So calling Xiaonan back at this time not only shows that the situation is indeed urgent, but also shows that they value him."

"You had the nerve to bring it up beforehand."

Zhou Li turned around and glared at Chang Yuanchao:

"You weren't even in the hospital when I gave birth to Xiaonan..."

Feeling his wife's resentment, the latter quickly grinned and retreated into the sofa.

But those words just now obviously convinced Zhou Li.

Chang Yuanchao, who is almost 50 years old, naturally thinks about ending his career safely, but Chang Haonan is only in his early twenties. It is when he is young and wants to work hard, so he really cannot let go of the opportunity he gets.

"If you leave tomorrow...then I will buy a ticket for you now. Are you going to the capital?"

Zhou Li said as she walked to the door and took her coat off the hanger.

"No need to buy a ticket."

Chang Haonan waved his hand to stop his mother who was about to go out:

"Time is very tight, I will fly directly tomorrow."

Zhou Li, who was halfway through her clothes, stopped immediately:

"Take a plane? Well... that must be quite expensive, right? Besides, it seems that planes to the capital don't come every day."

"It doesn't matter, there will be... there will be a temporarily arranged flight. I will just take that flight when the time comes."

Zhou Li was obviously stunned when she heard this explanation.

Chang Yuanchao, who had just retracted, sat up straight again and looked back at Chang Haonan, who was still standing next to the phone.

Both of their eyes were a little more shocked.

Of course not because of things like flying.

From their point of view, their sons are already designing airplanes, so flying is not the same as eating and drinking.

The point is that "temporary arrangement."

Generally speaking, you have to pay for the travel expenses back to school yourself.

Of course, this was after all, calling people away during the holiday, so it was reasonable for the superiors to be directly responsible for solving Chang Haonan's itinerary problems.

However, the couple who have worked in the system of a small county town for half their lives, the most they can think of is to reimburse their travel expenses.

After all, it is still an afterthought. You have to pay for it yourself first, and then you can get the money when you get back with the ticket. The process is often not so smooth.

If you meet a cashier or accountant who is not a good person, it is not surprising that the card will be on the card for several months or even half a year.

So Zhou Li was just making arrangements to buy tickets.

But Chang Haonan told them directly this time——

There was a plane, and it was specially arranged for his itinerary.

Naturally, the old couple had no concept of chartered flights. In their understanding, this was a private flight.

What kind of person does it take to have a private plane?

The couple actually didn't know this issue clearly.

But at least the biggest official they have ever come into contact with, the secretary of Liucheng City, definitely doesn't have one.

But the son in front of him is there.

After a long time, Zhou Li hung the clothes back on the hangers, the shock in her expression still not completely gone.

"Your dad is right, Xiaonan, you are going to be successful..."
