The sketch of the variable-cycle micro engine was actually from the scientific research institute of the previous mission world, which was in a state of cooperation with many research centers at that time, including some research institutes specializing in aero engines.

These institutions have obtained some iconic engine technologies belonging to the second-level civilization, a sketch of the structure of a super-thrust ion engine, which is not like the ion thrust made by the technology of the earth at that time, and the thrust of 100 kilograms of equipment is only a few tenths of a kilogram, but a kind of equipment can provide hundreds of kilograms of thrust good things.

Then I found that Zhang Tiancheng's set of temporarily assembled personal aircraft was too inefficient, but it was only a technology on the earth, and it would definitely not be able to create a pure super-large ion thrust in a short period of time, so I borrowed from the top aero engine technology on the earth at that time, and tried to make an engine that integrated high-thrust ion propulsion technology, and gave some earth-specific technology to extraterrestrial friends as a gift.

It's a pity that the time is a bit short, and the design has not been completed Zhang Tiancheng has returned, so this sketch is purely a half-pull project, and Zhang Tiancheng has no hope to produce it.

However, I heard that Lao Xu still has a classmate working in the Aviation Development Research Center, so he transferred the half-finished product data to him and asked his classmate from the Aviation Development Research Center to help see if it can continue to be improved and then produced.

Unexpectedly, a sketch was for the other party to visit in person, for aero engines or something, Zhang Tiancheng is of course a pure layman.

Even if I have seen the second-level civilization super large ion push, he is still a layman, and it is not easy to explain the origin of the sketch, so I just randomly found a reason to say that when I was traveling in Thailand, I accidentally picked up a USB drive on the beach, and then found that there was a new engine sketch in it.

"Boss Zhang, your luck is too good, how can you pick up this kind of thing, and it can still be used?"

"Who called me a good person, they all say that good people have good rewards, Dr. Liu came here specifically for the sketch?"

"Well, it's a very advanced design concept that involves the reuse of combustion exhaust gases and the use of high-temperature reflectors to accelerate air flow......"

"Doctor, you tell me this, I don't understand, or tell me something?"

"Originally, I was instructed to inquire about the team that designed this sketch, but now it seems that this technology is very likely to be the technology of Lao Meizhen to demonstrate the technology of the next generation of engines...... Boss Zhang's sketch was really picked up? ”

"Well, in fact, I risked my life to infiltrate the Pentagon and steal it, so as a government representative, you can watch it, but you can't let me work in vain."

“…… It's true? ”

"What do you say?"

"Boss Liu, don't be kidding, okay?"

"You don't believe it when you say it's picked up, you don't believe it when you say you steal it, what else can you do, do you think I'm a courier delivery student, and I can still draw such a complex engine sketch?"

"Okay, even if it's picked up, we need to learn from the sketch, you don't object, right?"

"Even the Eagle Sauce Bear's objection is invalid, what else am I against, anyway, the sketch has been borrowed from your hands casually, if there is any benefit, don't forget that I also have a small contribution."

"That's for sure, isn't this going to claim the grand prize for your personal aircraft?"

The two chatted in the office for a long time, Liu Danian consulted for a long time, and he was 100% sure that Zhang Tiancheng was a layman for aero engines, although many times the imagination was about to fly out of the galaxy, but it was not realistic at all, so he could only say goodbye and leave.

He truthfully reported the situation, and he really believed that the sketch was just picked up by accident, otherwise he would not have been able to explain the origin at all.

This famous brother on the Internet, but he is notoriously lucky, when he went to Myanmar to play, he could accidentally buy a super ruby rough and sell it for a sky-high price, although it was not directly announced, but it was not a top secret.

After sending off researcher Liu Danian, Zhang Tiancheng, who returned to the office again, fell directly on the sofa, lazily and didn't want to do anything.

There are indeed a lot of people I met today, and many of them are government workers, although I can also find an excuse to push away the nobody.

It's just that I still want to run the R&D center well, so sometimes I still have to meet people from all walks of life, but for Zhang Tiancheng, this kind of thing feels more tiring than fighting.

After no one else disturbed him, Xiaoman habitually sat next to Zhang Tiancheng, anyway, every time he stood alone alone, this boss always pulled himself to sit down, so he would definitely sit down without outsiders, and he would sit down next to Zhang Tiancheng's body.

And Zhang Tiancheng was not polite at all, leaning his head on her leg, and Xiaoman also massaged it casually, of course, it was not a very intense Thai massage, that is, to help rub her temples or something.

"Xiaoman, where are you going to take your sister to play after work?"

"Boss, you are the landlord, shouldn't the boss take my sister out to play?"

"Actually, I'm not very familiar with this place, and I haven't even stayed as long as you...... Otherwise, if you go out to play, I will pay for the expenses, so that I can be regarded as a landlord. ”

"That's still it, just the two of us girls go out at night, what if we meet bad people."

"How can there be so many bad people."

"Didn't you say just in case?"

"Okay, I'll be your bodyguard!"

Zhang Tiancheng could only agree, but it was a little strange that this Xiaoman girl should not want to see herself and her sister have too close contact, so she couldn't deceive people by inadvertently revealing her eyes.

But the actual action always pushes her sister to her side intentionally or unintentionally, which makes Zhang Tiancheng a little inexplicable, and sometimes she will be confused.

For example, when I watched a movie together in the living room last night, I was squeezed in the middle by the two sisters, and I couldn't describe it, anyway, I didn't remember the content of the movie at all, and all I was thinking about was some unspeakable things......

"Boss, look, why is our company on the hot search headlines." Xiao Man suddenly said something, waking up Zhang Tiancheng, who was full of cranky thoughts.

"In fact, it's useless to be on the hot search, that person's aircraft is not aimed at the ordinary people's market, and those who want to buy it know even if they are not on the hot search."

"It's always good for the company to be famous, and it can also reduce advertising costs by selling other products in the future."

"You're right, dinner time is coming, call your sister to eat together."

……

Said to play together Xiao Man didn't come out together, although I suspected that the girl was pretending on purpose, otherwise how could it be so coincidental, just went out and said that he was not feeling well and wanted to rest early, and then the threesome also became two.

In other words, Xiao En has really never seen any girls in the world, and at the age of seventeen, she has hardly left her hometown town, so she can say that she is curious about this time abroad, and she is a little lingering for the dreamlike night scene.

It's not that she doesn't care about her eldest sister, in fact, she said it from the beginning, and she knows why her eldest sister is saying that she is not feeling well.

Originally, she was still a little worried about the eldest sister's proposal, but when she found that there were only two of them, when Boss Zhang always appeared like a very kind big brother, the innocence of a girl was completely displayed.

This adds a bit of charm to her, at least for Zhang Tiancheng, it is still quite attractive, of course, in general, it is more appreciated.

If you really want to say that something unspeakable happened, it is still her eldest sister Xiaoman who is more suitable for the palace, but unfortunately there seems to be something wrong with that girl, and at most she can hug and kiss.

"Big boss, let's go over there and ride the roller coaster, okay?" Seeing the roller coaster, Xiao En pulled Tiancheng's hand again to get on the car.

"You go play, I'll wait for you here." Anyway, I was pulled on the merry-go-round by this girl before, and under the watchful eyes of a large group of children, it really felt so embarrassing to sit there and shake it, so I directly rejected the other party this time.

"Let's go together, I don't dare to sit alone!" The girl took Zhang Tiancheng's hand again and began to sprinkle Jiao, Zhang Tiancheng, who had already made up his mind not to go to the gear, was shaken by the other party, shaken two or three times, or defeated and took the girl to swipe the ticket and get on the bus.

It's just a little strange that after getting in the car, I can't help but think of a horror movie, which is the Grim Reaper 3 that I just watched yesterday.

Of course, there were no accidents on the roller coaster, except for the two buttons of the girl next to her, everything was normal.

In other words, this girl is also a little funny, her feet are still trembling when she gets out of the car, but her emotions are too excited, holding Zhang Tiancheng's arm and chattering non-stop, I can't wait to come a few more times.
