A little after 6 o'clock in the evening, Lei Banfei came to Jiangning University, and the appointed time was just right.

"You're quite punctual" Downstairs, Lei Banfei saw Li Yaqin. The light blue dress and the faint fragrance of osmanthus instantly make people feel a lot closer. Under the street lamp, her delicate facial features, long hair, and casual clothes give people a bright feeling. Lei Banfei stared at the woman in front of him a little distracted, and for a moment forgot what he was here for. Li Yaqin coughed twice, and Lei Banfei seemed to have recovered from a state of distraction.

"Today...... It seems like...... It's not the same as yesterday," Lei Banfei didn't dare to look at Li Yaqin's eyes, and said implicitly.

"What's the difference," she asked, smiling.

"It's not like a lab worker today"

"Are you saying I'm not the right person for the job?" She saw Ray-Ban Fei's mind and deliberately teased him.

"Oh, no, no, no. That's right, don't get me wrong, I mean you have a variety of styles and are suitable for different outfits, this is to appreciate you" Lei Banfei quickly explained, Li Yaqin teased, he didn't know how to speak.

"Okay, okay, I'm joking, let's go" She looked at Lei Banfei a little nervous, and she didn't realize a smile on the corner of her mouth. Although her age is not very old, in her eyes, this kid in front of her is more immature than her.

Li Yaqin took him to the workshop downstairs, Lei Pengfei wondered in his heart, did he say that he was wrong, some people said that he had low emotional intelligence, it seemed that it was still reasonable.

When she came to the workshop downstairs, Li Yaqin skillfully jogged the button on the display, set up the operation process, and the whole set of equipment began to operate.

After the drawings were scanned, the fully automated robot inside seemed to be activated. First, five or six mechanical tentacles came up and began to disassemble the six wings. Each time a part is removed from the six wings, it is scanned, and the parts of the six wings are numbered. After the numbering is completed, it will be compared with the newly entered drawing, and the scope of changes will be judged after the comparison is completed, and if the removed parts are really useless, the parts numbering will disappear, and the parts without the number will be automatically recycled. Lei Banfei looked at the six wings being * there, and couldn't help but be a little amazed in his heart. He was amazed at how highly automated and efficient the entire system was.

Looking at the six wings in the decomposition, he was a little worried, but also a little expectant. I was worried about whether it could be restored, and I was looking forward to whether it would be as perfect as the one on the 3D display.

The redesigned hexapon retains the original number of thrusters, except that they were previously placed on the lower legs, but now on the left and right sides of the two feet, but not vertically, with a slight oblique angle. The pair of wings on the waist were retracted to the middle, also at a slight angle, and it moved the wings that had previously had the most thrust from the back to the waist. The previous overdrive section on the back is also a little diagonal. Lei Banfei looked puzzled, he circled around the monitor, trying to find something.

Li Yaqin looked at him circling around the display and smiled, "Why are you circling around" because he tilted his head and looked really funny around the display.

Ray-Ban replied embarrassedly, "I want to see how this thruster is designed to be oblique, it looks a little uncomfortable" because his appearance is really funny, and he himself is a little embarrassed.

"Where do you want to see, don't you turn it with your hand and it's over" Li Yaqin gave him a demonstration. "Like this" Sure enough, Li Yaqin's hand moved slightly, and the image displayed on it also moved.

"This one is a bit advanced, how did you get it," he replied honestly.

"Come, I'll tell you about this thing" Li Yaqin led him to the computer screen next to him. "This is an automated, stand-alone manufacturing integration system with a scanner in it. It scans the object, and after it scans, it is automatically imaged. Do you see the bottom of the display?" Li Yaqin pointed to him with his hand.

He looked down his finger and saw that "it was just an ordinary piece of transparent glass" and that it was indeed a transparent glass when viewed from the side.

"Look closely" Obviously, Li Yaqin was a little angry at Lei Banfei's sloppiness, "Look at it from above"

Ray-Ban was puzzled and stuck his head directly above the 3D display. This look was startled, it turned out that it was densely packed with holes smaller than the tip of a needle, and all the light came out of those small holes, and strangely some of the holes glowed, and some of the holes did not shine.

"Put your hand in," Li Yaqin smiled weirdly.

He looked at Li Yaqin's weird smile, "There won't be any danger, right?" he didn't know what the hell she was doing, but he still put his hand in. "Wow" startled him, and his hand quickly retracted. It turned out that when my hand went in, it turned into a very strange color.

He thought his hand was hurting, "What the hell is this, how did my hand disappear just now" He was still in a cold sweat on his head.

"Don't worry, you're not injured, it's just that your hand is hidden by the light, you put your hand in and move, you're looking at the light source below" Li Yaqin replied happily, at this time, she was already smiling from ear to ear.

Ray-Ban Fei plucked up his courage this time and put his hand inside. Sure enough, I didn't feel it at all, because it was so sudden, I didn't look closely, and it turned out that my hand had turned a transparent pale green, just like the color of transparent glass from a section. His hand snapped, and the tiny light underneath moved with it. Those rays of light would change angles as his hand moved. If his hand removes the area of light, then that piece becomes transparent and nothing. It's just that the light that moves with his hand is also extremely subtle. "Wow, these lights move," he said in surprise. "This is fun," he said, his hand moving wildly inside, and constantly changing his gestures.

"Use your hand to gently move the thing shown in the middle" Li Yaqin stood next to her, looking at this cute and silly boy. She didn't have the excited expression she had just now, but looked at him with caring eyes.

After listening to it, Lei Banfei approached the image of the six wings displayed in the middle with his hand, and after getting closer, a magical scene appeared, and his fingers obviously didn't feel it, how could the image in the middle move with his fingers. It's all like it's real, it's the light in the middle, it's all magical.

"Is it fun?" asked Li Yaqin.

"Fun, fun. How is it all done" Ray-Ban Fly, which will be very exciting.

"First of all, your hand is not disappearing, but the refraction of light. Actually, if you don't look closely, when you put your hand up, the light will cast a different image on your hand, thus hiding your hand, and as for the transparency you say, it will project the shadow side of your hand, which is the back, to the front. When you put your hand in, you can only see the back of your hand, not the place below your palm, and these rays will present what you can't see below your palm on the back of your hand, like this......" Li Yaqin's hand gestured inside, and he was dumbfounded.

"Is it possible to control the light?" is true that the light goes in a straight line, but at most it is to project an image on the palm of the hand, and the back of the hand is on it, so how can there be a projected image? Could it be that there is also a light source on it, he looked up, but saw nothing.

"Okay, I can't tell you the rest" After speaking, Li Yaqin took her hand back, as if Lei Banfei had said something wrong just now, or said something sensitive.

Ray-Ban also took his hand back. "Like this, how long can the improvement and upgrade work be completed" It seems that he is still unsatisfied, or he can't wait.

"If it's fast, it will take 24 hours, and if it's slow, it will take another day."

24 hours, Lei Banfei remembers the first time he did the hexawing, and it took two weeks before and after. The main thing is the processing of parts, so, 24 hours, is already beyond his imagination "It's already fast, it's been fast" He can't have more requirements.

"The whole system will break down your flight rig into several parts and send them to each unit for simultaneous upgrades. The real-time retrofit process will be shown here, the whole system does not need to be supervised, it is working 24 hours a day, and if it goes well, your flight will be ready tomorrow night." Sure enough, the monitor next to it kept flashing the progress of each part processing. After processing, it will be marked directly on the drawing, and the machines here are all working at the same time, so there will be no delay.

Lei Banfei stared at the progress bar on the display screen and moved little by little, thinking in his heart: After this is processed, what will it look like, will it be the same as before......

"I'm afraid you won't be able to go back tonight," Li Yaqin's words interrupted his train of thought.

"That's not good, I have something very important tomorrow" Indeed, how to get back tonight is a question.

"Tomorrow you can spend a day in Jiangning City, what a good thing. You go back, what should you do with this thing, and how important things you can be" In Li Yaqin's eyes, Lei Banfei was like a little brother. What important things can a child of his age look serious.

"The automatic defense system sent from Jiangning University has already arrived at us, and it will be installed and debugged in the next few days. After that, the whole system is tested and run. We don't want to be absent, the modified flight device, I'll come back tomorrow night to get it" Today, during the day, the things that Song of Jiangning University used to pass were just counted on the spot. Professor Song hopes that all the defense equipment can be installed, and after the installation is completed, it will be debugged, and there are still many things to be done in the future. Although he, as a sophomore, may not need them in normal times, but now is an extraordinary time, and all the teachers and students in the school have arranged their own jobs, so Lei Banfei must go back.

Tianzhou University has unique conditions, and every two years, the school's teachers and students participate in such a competition. Not only did I learn knowledge, but I also gained knowledge. Of course, other schools can also send people, but only a small number of them come, and almost all teachers and students of Tianzhou University can participate, this is a better opportunity to exercise, so everyone cherishes it, and the teachers and students of the school know what it means, so everyone will not be absent.

"It would be nice if it could be modified tonight" It was not too early now, he sighed a little, "What if I can't go back"

"It's so fast, you see, there are so many precision parts on it, it takes hours just to do the mapping, cutting, manufacturing, and polishing all the processes. After the modification, I had to run an all-around scan and run the simulation on my computer several times. You want to fly at such a fast speed in the air, and if there is a part that is airtight and the connection is loose, is there going to be a big problem, what if it disintegrates. ”

Although Ray-Banfei knew that every time the six wings were lifted off, Raybo would do a flight evaluation, but this time, it was not up to him to decide, and it was better to do it according to what the professional mechanical engineer said.

He looked at the time, and he had to go home early. But whether it is an airplane or a high-speed rail, it is not as convenient as the six wings, does he have six wings travel dependence? "It's over, now you say it's too late for me to buy a plane ticket or a high-speed rail ticket" Thinking of this, he was a little anxious.

Li Yaqin looked at his watch, it was now more than 7 o'clock in the evening, "Let's go, accompany me to the restaurant for a meal, I will find a car to send you back later" In fact, he is not in the mood to eat now, but there is no way, so far, Lei Banfei can only do what Li Yaqin said, accompany her to have a meal, but he must rush back tonight.

At 7 o'clock, there were still a lot of people in the school cafeteria, sitting together in twos and threes. After the two of them ordered a meal, they found a seat and chatted while eating.

"Hey, we've met twice, I don't know what your name is" Or say that Li Yaqin is two or three years older than Lei Banfei, so as to avoid the embarrassment of this boy, so I spoke first.

"My name is Lei Banfei, I'm a sophomore this year, so ...... you" To be honest, in the laboratory, two people can talk about something else, distract themselves, or have a common topic, and they don't feel that something is wrong, but sitting together like this, he is still a little shy.

"My name is Li Yaqin, and I am two years older than you. Did you design that thing?" was the second time she asked about the design of the six wings.

"That thing...... Even if I designed it, I didn't design it" Strange, why does she keep asking this question, does Six Wings really interest her so much.

"What do you mean?"

After the topic of "I can't say it yet" was discussed, the atmosphere was much more relaxed. "Alas, sister, how are you preparing for that competition at the moment" He quickly changed the topic of Six Wings, because if he continued to ask like this, he didn't know if he could keep this secret.

"It's still in the testing stage, and when it's time for the competition, you can see it" Li Yaqin saw that Lei Banfei refused to say, and she also sold it.

"Why are you always in and out of the lab, sister, don't you have a boyfriend" Lei Banfei sat opposite, stirring the smoothie with a spoon, and asked "You are so beautiful, there will definitely be no less suitors"

"Every day, I am either in the laboratory, at home or in the dormitory, and I rarely go out, and the circle is too small. I don't have the time or the heart to talk about this, what about you" Indeed, her life is a bit boring, maybe there is something hidden, or maybe she didn't find the right one. And an excellent girl like her must have a high vision.

"I'm still young, and it's not time to think about it."

"Really, don't you go to school every day and see other people one-on-one, and you don't have any other ideas" Li Yaqin raised her head and stared at Lei Banfei, with a little smug expression on her face.

"I think boys still have to have a little bit of ideals and pursuits. Besides, I don't think my emotional intelligence is very high, and I get nervous every time I talk to girls, and I often make the scene very embarrassing......" Lei Pengfei said very quietly, saying this in front of a girl, it is indeed a little embarrassing.

"I think you're okay, I can't see that you're nervous" She could see that he was a little shy, in line with the characteristics of a teenager, although he was not a few years older, but in college life, every year was different.

"That's because we have a common topic, and if we are alone with other girls, there will be a little ......" He didn't know how to explain, maybe it was because there were few common topics.

"Alright, I'm not going to intrude into your privacy. Let's go, find you a car, and send you back" Li Yaqin wiped her mouth and said to the boy in front of her with a smile. I don't know if the kid in front of her really has low emotional intelligence or deliberately teases her, but she can feel a sense of superiority from him other than work, which makes her very happy.

The two walked downstairs to the laboratory, "You wait for me here for a while" After speaking, Li Yaqin walked into a corner. Within a few minutes, a car slowly drove out of it.
