Li Ying's father is named Li Zhengku. He is in his fifties. He was transferred from the local military division to the armed forces five years ago. He had a strong military scent, gray short hair, and a majestic and slightly fat body. He stood there. Even if he was not wearing a military uniform, he could tell that he was a soldier.

Comrade Li came this time when he was invited to have the full moon wine of his old comrade-in-arms grandson. Just as Li Ying was about to return to school, he left for two days and turned a corner and followed him to take a look.

Although Li Ying's father has always had the idea of ​​favoring boys over girls, it is not that he looks down on Li Ying, and he talks ill-heartedly all day long, either beating or scolding.

On the contrary, there is no less care that my father should have.

But I always think that there is no son in my heart, which is the biggest regret in my life, and I always keep similar words on my lips. The only time I really got angry with Li Ying was the time when Li Ying secretly changed her college entrance examination application.

Previously, Li Ying accidentally killed a robber with a short crowbar, and then she had some psychological problems. Although it was resolved in time after treatment, the school notified her parents with a responsible attitude towards the students.

When Li Ying's mother found out, she cried and shouted that she was about to go to school to see the girl, but was stopped by Li Ying's father. She stopped her wife not because Comrade Li didn't care about her girl, but because he thought that since the school had said that there was no problem, her wife would just cause trouble when she went there.

As for children, if they are alone, they will learn to be strong even if they are forced by the environment. If their parents go there, they will become weak again.

Although Li Ying's father's words sounded very hard, he was extremely satisfied with his girl's performance. He went out and publicized it all the time.

One mouth opened: "My girl is really a species from the old Li family. In the middle of the night, I met two kidnappers who tied up children. They went up without saying a word. They knocked one to death, and the other one was also half-dead."

Li Ying's father was so beautiful that Li Ying's mother was so worried. He thought to himself that his girl was like a tomboy, and now her reputation as a "tiger" is confirmed. Who dares to marry her in the future?

Li Ying's mother was so worried. When Li Ying returned home last summer vacation, the father and the other two secretly ran out for a big drink. After they came back, they became a group. For the whole summer vacation, Li Ying basically accompanied her father to work every day, and didn't stay at home much.

This time, Li Ying's father heard that his girl and her classmates were studying drones and preparing to participate in the design selection of universities across the army in April. He turned a big bend of nearly 400 kilometers nearby, saying that he had a long experience.

Li Ying's father is here, and Qu Sen and Zhou Li are naturally obliged to accompany him as Li Ying's friends. A treat is naturally indispensable. Qu Sen was also pushed to accompany him for a drink.

After drinking more than eight liang of white wine, Comrade Li didn't have anything to do. Comrade Xiao Qu, who couldn't even walk straight while patting the road, kept saying: "Qu Sen, you still have to practice your alcohol tolerance. You can't even drink a pound of white wine from the army, how can you do it?"

After the meal and the meal was served, the next step was to take Comrade Lao Li to visit the drone.

Although it was still a prototype that didn't even have a shell, Comrade Li had already hit Li Ying before coming, and learned about the great ability of this "remote control toy". With the help of alcohol, he personally controlled the flying for a while.

Looking at the night vision images transmitted back from the laptop screen, I smashed my mouth and sighed: "Good things, you can also use fire prevention and theft prevention during the New Year holiday. If you are not afraid of water, patrolling the dam during the flood season can be of great use."

In addition to assisting in recruitment work every year, the local armed forces department is also responsible for organizing reserve training, fire prevention and flood prevention in the dry season, rainy season, etc. Li Ying's father started from his job and saw some of the use directions of drones, which also expanded inspiration for Qu Sen and the other two.

So I immediately decided to add the application prospects of drone-assisted surveillance disasters in the copywriting introduction when I ran for election.

After staying in the school guesthouse for one night, Comrade Li took the train and headed for his old comrades' house again. Qu Sen and the other two gathered their energy and devoted themselves to the development of three drones.

However, this time the three of them temporarily put down their software and began to shift their focus to hardware structure design. The reason is that Zhou Li went home this time and talked to her father about the difficulties facing the three drones.

When talking about the paddle making issues and the mold opening of the shell, Zhou Li's father said that their unit had just entered a special 3D printer, which not only had super high accuracy, but also supported a variety of special printing materials.

After they got it, they tried to print a pistol, which had a material toughness that could support more than ten firings.

If the drone made by Qu Sen and the other two is a mature product, the printed shell and paddle may still have problems with their service life, but what they are doing is to take the lead in the works, which are experimental, and it is amazing to print out a few sets of spare parts.

Although the cost of special printing materials is not cheap, it is basically just a fraction of the time compared to opening the mold.

Qu Sen and Bashu electrical appliance manufacturers and May 11 confirmed the detailed parameters of the motor and high-precision gyroscope. They first designed the internal structures of the three drones, and then based on the internal structure, the shell design was completed with the fastest speed.

It was already the end of February when these work was finished. Seeing that there was more than a month, the formal selection was about to begin. The three of them took the letter of introduction issued by the school and boarded the train.

Before boarding the train, Qu Sen and the other three received very bad news. The school's "investigation" results showed that the organizer of the assembly event had received no less than 30 applications for small drones to run for election.

This means that the three of them originally planned to be novel and eye-catching as their "tactic" simply wouldn't work, and they could only compete with other colleges and universities for hard strength.

Although Qu Sen and the three have the full support of the school, Professor Wu’s technical support in wireless connectivity, and May One helps overcome the difficulties in software and drivers. But looking at the major universities across the army, the communications-related university is not the only one.

In addition, more professional electronic engineering colleges and aviation industry-related colleges, those guys have truly strong resources to use.

However, no matter how worried you are, you have reached this point, and you have no turning back and you have to push it up even if you grit your teeth.

More than ten hours later, the three of them got off the train and got on the bus to pick up the station. They bumped for almost two hours before they arrived at Zhou Li’s father’s work unit.

Qu Sen probably knew that Zhou Li's father was a very famous military designer in the military, but he was not clear about the specific unit. When he sat in Beijing 2020, who was sitting in the pickup station, he thought he would be taken to a very secretive high-end scientific research institution that was underground or semi-underground.

But after arriving at the place, I found that the three of them had been pulled to a military factory courtyard located at the foot of the mountain. Although it covers a large area, it has old buildings all over my eyes.

Not to mention, the factory brand with black and white characters hanging outside the gate is a bit painted. Although the snow in the courtyard has been cleaned up very clean, when you look closer, the cement exterior walls of many old-fashioned buildings have cracked and fallen off. There is a red brick building even more exaggerated, and you can see clumps of yellow weeds on the roof, and even a meter high with a few dead leaves hanging on it.

"This~ Can people live in this building? There are trees growing." Li Ying sat behind the car and couldn't help but mutter.

"That's an old factory, it's empty now." The driver explained casually.

The factory area is indeed very large. After entering the gate in 2020, it took more than ten minutes to open it before the driver parked the car outside a half-new and four-story building. Qu Sen saw through the window that there were three gilded iron characters above the building gate - the guesthouse.

The three characters are not only seriously rusted, but the vertical part of the right half of the character "典" is also welded. What cannot be removed looks like a "典", and a gust of wind blows and sways.

"The chief engineer is very busy today and it will take almost to finish it in the evening." After parking the car, the driver began to explain: "The guesthouse has opened a room for you, just go to the cafeteria for dinner. I will come and take you there at that time, and I will be there after the hospitality talks, a few steps."

"Thank you, it's causing trouble." Qu Sen quickly said politely.

The driver didn't talk nonsense and took the three of them into the guesthouse. The front desk receptionist didn't know whether it was a soldier's family member or an employee's elder sister. After checking the three of them's IDs, he gave the driver two keys and asked him to take people to the room.

The two standard rooms on the second floor are next to each other. The rooms are clean and the heating temperature is OK. However, they are very old. Although there is a shower, there is a note next to it, which says the time for hot water to be supplied.

The TV is not much bigger than a washbasin, and there are not many units available. What Qu Sen didn't expect most was that there were two thermoses standing in the room. The big red bottle body looked very festive, but it was a bit old.

After the driver left, Qu Sen entered Zhou Li and Li Ying's room. The two girls wiped off the mist from the glass and were crawling through the window and looking out strangely.

When Qu Sen approached the window, he could vaguely hear the sound of early revolutionary songs. He looked out along the eyes of the two of them and saw a group of warriors wearing vests digging trenches in the distance. If Qu Sen's eyes were fine, the source of the music should be an old-fashioned dual-slot recorder.

"Hey, you said that if the people in this courtyard changed their military uniforms to the old-fashioned ones, would they be able to film themed TV series from the 1950s and 1960s?" Qu Sen lay beside Zhou Li and muttered outside.

"I don't want to stay back by myself!" Zhou Li said angrily.

It was also her first time to come to her father's office. She thought this was the kind of research institution that looked like a variety of high-end and elegant. After that, Miss Zhou, like Qu Sen and Li Ying, her eyes almost fell off.
