Ray-Ban kept spinning around at home, neither standing nor sitting. After he saw these pictures designed by Rapo, he was even more disturbed, and he had an inexplicable sense of anxiety. Now it's not a question of deciding whether to do it or not, it's a question of how to open up to the other party, what if he refuses, he wants to make a name for himself in the tournament, but he doesn't have time to give it to him.

"Forget it, no matter what"

"Hey, who are you?" Lei Banfei thought about it in his heart for a long time, and finally mustered up the courage to dial Li Yaqin's phone.

"I'm sorry, I'm very offensive to call you" He simulated the first call countless times in his mind, but as soon as he opened his mouth, he didn't know what to say. Maybe it's unfamiliar, and I can't figure out the other party's temper.

"What's the matter, say it quickly, I still have something to be busy here", Li Yaqin put down the things in her hand, and the successive phone calls made her a little angry, especially when she was concentrating on things.

"What do you say, I want to visit you" On the phone, Lei Banfei felt that the girl on the other side of the phone was very strong, and asked cautiously.

"Visit me, do you have anything? Who the hell are you? The person on the other end of the phone was inexplicable, Li Yaqin obviously lost his patience.

"Did your junior brother Wu Wei call you this afternoon and send you a photo" Lei Banfei heard that Li Yaqin's tone was wrong, and quickly got straight to the point, he was afraid that the other end of the phone would be the same as in the afternoon... Honk... Hang up, "Are you interested in that thing too?"

"I'm not interested in it" sounded like Li Yaqin was really angry.

"I'm that thing," Lei Banfei didn't know how to answer, and told her the truth.

"Oh, I know, my junior brother told me about that flying machine, but I've been very busy lately, and I haven't studied it carefully" Li Yaqin's tone softened a lot after she cleared up. After all, that person saved his classmates and teachers, and it stands to reason that she should say words of thanks, but she is not in the mood for this.

"Actually, if you are done, I can go over, it shouldn't delay you for a long time" It seems that after he revealed his identity, the other party did not mean to hang up the phone in a hurry, so he made another request.

"Tianzhou City is more than 700 kilometers away from Jiangning City, can you come over in time now" Li Yaqin knew that it was not good to refuse directly, so she found a reason to end the call this time.

Li Yaqin didn't know that the questions she raised were not problems at all in Lei Banfei's opinion. Far away, he wanted, the six wings could easily reach twice the speed of sound, 2,500 kilometers an hour. Space wasn't a big deal for him.

"I can fly over, it won't take long, it will be there in 30 minutes" Lei Banfei saw that the other party was relieved, this reason was not difficult for him. He desperately wanted to get over, and even if it was dark, it wouldn't take long for him.

"Then it's up to you" Li Yaqin couldn't think of any other reason for a while, so she had to agree first. Besides, it was already dark outside, and maybe he was already busy when he came, and there was nothing wrong with talking to him.

"I'll be there in a moment, where will I look for you? Do you have a lab there? Ray-Ban didn't think so, he didn't want to miss any details, because when he got there, he had to ask a professional mechanical engineer to carry out a series of analysis and processing of the six wings. He thought about it, and if the other party wanted to disassemble the six wings for research, he would leave the six wings there. "I'd like to hear what you think of this thing."

In fact, seeing that the competition is approaching, Li Yaqin has been busy in the laboratory until late recently. She was going to finish the last piece of her work. "I'm in the laboratory now" It seems that the other party insists on coming, and he may not leave tonight, but he wants to come to the laboratory, which already explains the problem.

"That's great, see you in 30 minutes" Lei Banfei was overjoyed, and saw hope for the improvement and upgrading of the six wings, and made up his mind even more.

700 kilometers is not very far for Liuyi, two hours by high-speed rail, maybe you can usually go to a supermarket. However, Lei Banfei and Li Yaqin agreed on 30 minutes, so he used the speed of sound in the air, and he couldn't be late for the first visit.

Recently, Lei Banfei has been thinking about a question, what will he, Lei Bo, and Six Wings look like after they are separated. He and Rapoo are strapped, but what about the six wings? , What if Rapoo is not there, and the six wings are dismantled and cannot be restored "What if there is no you for a while, what should the six wings do, what if they are dismantled and the upgrade work cannot be completed before the competition" It seems that he is too optimistic, and upgrading the six wings is not as simple as he imagined.

"If I wasn't there, the hexapon would be dormant, and only I could activate the hexawing's power system, don't worry. This time it can't be regarded as an upgrade, but a redesign and processing" After listening to Lei Poo's answer, Lei Banfei was a little relieved. And now he also understands that maybe this time it is not an upgrade of the six wings, it should be regarded as a redesign, and if it is redesigned, there will be no problem of restoration or non-restoration.

"Have you prepared all those sets of drawings just now?" He was afraid of missing any details. The first step is to listen to this professional's opinion on the six wings, and then put forward his own upgrade plan, if you agree, then take out these sets of drawings to her, and then listen to her opinion, and then choose one set to upgrade, and the rest, just wait for the finished product to be made. Thinking about the redesign and processing of the six wings, he felt a hint of joy in his heart.

"The drawings are ready, if necessary, I can design more drawings, but there is no need for that, just look at these sets, whether she can complete them" Lei Bo said these words, Lei Banfei could not refute. Because he knew that Rapoo could design what he wanted with very fast calculations. For them, maybe it's not a question of whether to design or not, but whether they can do it, if they want, Rapoo can design hundreds of different flying armor drawings, but they can only choose one, too much makes no sense.

In just half an hour, they had already arrived in Jiangning City. This is Lei Banfei's first time going far away, and he is a little curious about places outside of Tianzhou City. The night in Jiangning is no different from Tianzhou. The neon lights of the night and the bustle of the streets seem to reflect the prosperity of the day.

"I heard that 30% of the country's equipment manufacturing industry comes from here, but I don't know if it's true."

When I entered the city, I saw the signboard of Jiangning University from a long distance. "Help me set the location of Li Yaqin's laboratory" Lei Banfei knew that the first time they met, they needed to be on time, and they couldn't be troublesome. He can't call and ask: where are you, how can I find you, how to get there, he can't ask these questions. And according to the phone call in the afternoon, Li Yaqin is also a person who is afraid of trouble. Lei Bo had already shown the location in front of his eyes, "Say hello to her" As soon as the words fell, Lei Bo had already dialed Li Yaqin's phone for him.

"Hi, beauty, I've come downstairs to you, are you on the third floor" He didn't let the six wings land, but slowly hung in the air. Because he wasn't sure if it was on the third floor, he parked a little below. If not, it's not good for others to see it.

Li Yaqin opened the window and looked down, and sure enough, she saw something hanging in the air. "It's here so soon, you come up, which surprised Li Yaqin. She originally thought that 700 kilometers would take two or three hours, but she really didn't expect him to arrive so soon, and when she was about to close the window, she heard Lei Banfei shout.

"Leave the window alone, it's a bit inconvenient for this thing to take the stairs, I have to go in through the window." By this time, he was already hanging in front of the window on the third floor. "It's really uncomfortable to ask someone to do something," Lei Banfei said to himself. Six Wing was still in flight, and in flight, he couldn't climb stairs, so he had to go in through the window.

"Come in" Li Yaqin packed up her work and stood there, waiting for the stranger's arrival.

He slowly floated in through the third-floor window and landed gently on the ground.

At this time, what caught Li Yaqin's eyes was a yellow delta-wing aircraft. Wait, it doesn't seem right, there seems to be a fault in the middle of this delta wing, it is not a whole, it is divided into three layers, and the connection with the main body does not seem to be fixed and dead. Looking closer, each layer seemed to have something similar to a thruster, and she was not sure, because structurally, these three layers of thrusters could be superimposed. Theoretically, delta wings are the most suitable for flight characteristics, like the paper airplanes we folded when we were children. But she had a question in her heart, how do people stay in it.

After landing, the middle part of the entire flying machine, which is also the middle of the pair of thrusters in the middle, is slowly separated layer by layer.

Li Yaqin turned her head to look at the yellow delta-wing flying device in front of her. Out of the open space came a teenager with clear eyebrows. However, when Ray-Ban came out of it, the expression on his face was indescribable. He kept a posture in the air for half an hour, which was indeed uncomfortable. However, when the two of them met in such a way, the scene was slightly awkward, and they were both taken aback.

Li Yaqin looked at the little boy in front of her carefully and didn't say a word. His eyes instantly swept to the flying device behind him.

But Lei Banfei's eyes never took his eyes off Li Yaqin's body. The girl in front of her has delicate facial features, long hair that is black and shiny under the light, and a faint fragrance of osmanthus on her body. This is Lei Banfei's first impression of Li Yaqin. Li Yaqin wears a lab coat from the laboratory. It's just that what he saw still couldn't hide the cold temperament on her. Well...... Maybe it can't be said to be cold and glamorous, it should be said that it is a temperament that does not eat fireworks in the world. Even if he doesn't eat the fireworks of the world, he is still attracted to the girl in front of him, maybe he is a little nervous.
