The brother and sister haven't been to high school for a long time, and they have no choice but to give up the midterm and monthly exams. The students of the pen and fun pavilion often inquired about them through Mu Xin and Ding Chaoyong www.biquge.info and both answered "I don't know".

The two of them actually know and don't say anything, especially about this drone, the less the outside world knows, the better.

In the opinion of star fruit, the secrecy of the matter about drones is not done well. But she doesn't have to worry too much, with the current level of scientific research, this drone is still decent, and spies are too unfounded.

Because she agreed to Mu Xin to go with her to do the wind tunnel experiment, of course, Ding Chaoyong will definitely go with her.

"In the end, one is richer than the other, and we all sit in luxury cars." Ding Chaoyong can wear a suit to be very formal, and his car is also formal.

Ding Xin bought a BMW for his son with a driver, which is standard and will only be used on formal occasions, so it is obviously necessary to make this event official.

"You're too mature, you haven't taken your father's class yet, but you're acting like a CEO." Mu Xin teased.

"Then look at the two of them, those two immortals are not dressed up and are very formal?" Ding Chaoyong pointed to the brother and sister who went out.

The workers in the unloading yard of Dexin Super Times are still busy, and everyone does not care much about the activities of their small bosses. In short, some people will talk about the fact that the bosses, who were quite low-key in the past, actually pulled the luxury car over this time.

Da Ming didn't hear people's discussions, and his mentality was quietly changing as he grew older. The money is earned by himself, and this time he pulled the Bentley that his hometown bought for some time to be worthy of his identity, and the chairman of the dignified Dexin company, he still has to do something on the pomp.

So he is dressed in a suit like Ding Chaoyong, and his experience far exceeds that of Ding Chaoyong, wearing this dress is still very manly in the eyes of star fruit.

"Look at the two of them, it's really husband and wife, and the wife puts a tie on her husband." Ding Chaoyong said suddenly, his expression was also hinting at Mu Xin.

"Okay, you also want me to imitate star fruit?"

"yes, aren't we both the same? Wife~" The word "mother-in-law" Ding Chaoyong deliberately elongated the sound, which made Mu Xin snort ambiguously.

Star fruit tied Da Ming and patted the dust on his shoulder. "Okay, now you look like a young man in the new era." Carambola is very satisfied with Daming, she is talented and beautiful, and she is also very beautiful.

The truck on the other side was loaded in the middle of the night, and the models of the two drones were foldable and are now compressed into a huge container. Mr. Fu Pengju and several researchers will go together, along with people from the military.

Hidden in the mountains, the wind tunnel was originally built in the sixties to prevent Soviet nuclear blackmail, but after the rapprochement with the Soviet Union, the significance of the bomb shelter was questioned, so it became an aircraft laboratory and installed wind tunnel facilities.

Because the location of the wind tunnel is still under military control, this is why the Dragonfly Research Institute has to take the military with it.

The so-called soldiers, the adoptive father of star fruit is a soldier, and this matter has attracted great attention after being reflected in the military region, and the wind tunnel has also received a notice.

The military vehicle opened the road in front, followed by two luxury cars, and several vehicles behind a heavy truck. The convoy drove into a hidden road in the mountains and soon arrived at its destination.

"Don't run around when you get here, beware of being used as a spy stealing state secrets." Mu Xin deliberately said to Ding Chaoyong.

"Okay, I don't dare mess with the soldiers."

Da Ming, who was sitting in the co-pilot, hugged his sister, and the two teased that they were not so nervous.

Coming to this serious place, seeing the armed sentries standing guard still made Ding Chaoyong a little nervous, although he had fought. After reading the documents, the sentry hurriedly notified his superiors, and all the tension was meaningless.

"I've received orders." In the office, Zhang Qiang, the person in charge, said to everyone. He especially looked at the cute star fruit: "I heard that your father is Hu Chenghe of the XXX regiment, but I didn't expect him to have a daughter like you." ”

Carambola smiled, "Yes, my family is full of loyalty, and I will contribute to the country in my generation." ”

Zhang Qiang is just an old officer who has been stationed here for 20 years, and he is not particularly worried about the flowery world outside, as long as he is a good person. This star fruit, he has heard of it, is the adopted daughter of the head of Hu Chenghe, and she is also a little genius. So today, this genius is going to borrow the wind tunnel with a drone, and as the person in charge, he must perform well.

After a simple lunch in the barracks, the group couldn't wait to go to the wind tunnel.

This air-raid shelter is very large, and it must have been built for large-scale evacuation. Star fruit looked up at the high ceiling, which was equivalent to a large warehouse.

Zhang Qiang introduced as he walked: "This air-raid shelter can accommodate nearly 100,000 people when it is designed, it is very large and deep, and the supporting facilities are very backward because of the age, even the wind tunnel has not been used for a long time, and there may be a lot of dust." ”

"Then let's start it and blow the dust out." Carambola Road.

"Of course you can, but there's one thing I have to say beforehand." Zhang Qiang was very embarrassed because the wind tunnel cost money. "The cost of an hour may be very high, and it is indeed free to undertake military projects here, but you are a private enterprise, and the electricity bill is still derived."

This thing is new, Da Ming asked weakly how much money it costs.

The money actually has to be used a lot, and Zhang Qiang didn't directly say that the price would make him look like a profiteer. "The wind tunnel here, the efficiency of the fans is three megawatts, and this is a subsonic wind tunnel."

Three megawatts is 3,000 kilowatt hours, and an hour is 3,000 kilowatt hours of electricity. "So that's 6,000 yuan an hour? I remember that it should be calculated in terms of industrial electricity consumption. "Star fruit said.

"The little girl is right, after all, the power plant also costs money."

"It doesn't matter, money is not an issue, we have to test our products."

Developing a new product is always a lot of money, especially if it's not your strong point. Wind tunnel testing is still necessary, not only to prove the strength of the aircraft itself, but also to verify the correctness of the aerodynamics of the airframe.

The experiment was held on the second day, and everyone spent the night in this barracks for the time being.

The evening of the barracks is not as noisy as the city, it is far away from the city of Hangzhou, the sky is already deep blue, and the Big Dipper and Venus are all high in the sky. It was a rare moment of solitude for the siblings, sitting on the flag stand in the camp, snuggling up to the sound of the army's trumpet.

The garrison here was only one platoon, and after dinner, they basically returned to the barracks. They don't become uncommon and strange just because they have guests, at most they talk too much.

"It turns out that you two are here, Mu Xin and I guess that the two of you will go back to the barracks to rest after eating." Ding Chaoyong said with a little harshness.

Da Ming turned his head to look at these two men, a man and a woman, they also have a marriage contract, and they are also accustomed to acting together. "Since we're here, let's sit down together and look at the stars and chat."

"It's really emotional." Ding Chaoyong pulled Mu Xin up, so that the four of them enjoyed the spring night.

The Milky Way is not visible everywhere, only the higher bright stars can be seen here. Carambola's delicate arm pointed to the sky, "That's Orion, and the three gold belts are obvious." There is also the Orion Nebula under the belt, which is beautiful if you have an astronomical telescope. ”

"Then why don't you ask your brother to buy you one?" Ding Chao said bravely.

"Okay." Star fruit looked at Daming and she had an idea at this moment, "I remember that Tuva was originally a plateau, and there are some mountains, where the climate is also very dry and the air is clear, which must be very suitable for an observatory." ”

In Da Ming's heart, wouldn't it be too exciting to tell her that the observatory was already under construction, so it would be better for the surprise to continue as a surprise. "The construction of the observatory is still slow, you always want to come out of it, every time you think about it, you must do it and succeed. Your brother and I, I'm going to break my legs. ”

"Does my brother's leg hurt? When you get back, you'll lie on the bed and I'll rub it for you. ”

"Look at the people. Mu Xin, my leg hurts too. "Ding Chaoyong deliberately coquettish.

"No, I won't rub it for you. Besides, if I want you to rub it for me, you will definitely be willing. ”

"Well, of course I'd love to."

The four of them laughed and watched as the stars in the school two began to talk about the school. Without the Yang siblings, the class was not greatly affected, and everyone was just looking forward to a sudden visit by the two. "Everyone studies very hard, and I have to fight hard, even if I ......"

"Even if you have a fortune, you don't plan to be a gentleman. Involved in a war, you are not the same person you used to be, and now you are becoming more and more manly. Mu Xin's praise made Ding Chaoyong very happy, thinking of his former self, he really went astray and was a rich bastard, even if it was a waste of life.

"So what are you going to do with this drone now?"

Da Ming didn't expect Ding Chaoyong to ask this, and his sister still knows about the purpose of drones.

"What else can I do? Fighting? "You must know that the world is not very peaceful, our war in Tyumen has made one person very excited, and now maybe my brother has heard about it, and the Chechen rebels have begun to be active again." I think that Putin must lead the troops again, for the sake of our interests in Tuva and the choice of the Tuvans, military intervention is very likely, and this drone must be built as soon as possible. ”

"War, war." Ding Chaoyong let out a long sigh, "Last time in the war, your and I were both hanging by a thread, but this time it's good, our army won't die if we use drones to throw bombs." Human, so cruel. ”

"Yes, I was very cruel. I've been the one who died twice, and it's a miracle that I'm alive. I can only try to live, even if I am a terrible arms chief. Star fruit deliberately put on a smiling face to show Ding Chaoyong, and his words seemed to be too explicit, which made him a little uncomfortable.

"Sister, you're talking too much. It's people who make wars, and weapons can destroy enemies and protect themselves, right? Da Ming argued.

"But after all, it's still to kill, the enemy is dead, and the friendly army is alive."

Mu Xin hurriedly shouted to interrupt everyone's cruel topic. "Don't mention any war, we are friends, here we bless everyone, and wish the people we love to live a long life."
