The two walked like this, and Lei Banfei wanted to speak several times, but he didn't know what to say.

Li Yaqin saw that he was still a little restrained, and asked, "Are there many people at the venue?" As a senior student, she has participated in such activities several times, and she is a person who has seen the world.

Her question opened Ray-Banfei's chatterbox, and Ray-Banfei told her a lot of things she had seen and heard at the venue. For example, I learned about some characteristics of biology, the development of the human brain, the greatest impact is on people's physical fitness, and I also learned that some people are actually doing research to change human organs, they are installing artificial organs for people with physical disabilities, and then directing the organs through the signals of the human body's response, so as to achieve some functional supplements. Of course, some cultivated human organs are indispensable, some are soaked in potions, some are transplanted in animals, and some use human cells as the mother, grow in the body, wait until the structure is formed, and then transplant it in the human body.

There is also a type of glasses that can see far away, and these glasses are equipped with smiling chips, which are connected to satellites and controlled by human eyes. The value of such glasses is that people will not regret missing out on some of the wonders of nature. For example, the fog pine of the Yellow Mountain, the smoke and rain of the south of the Yangtze River, the waterfall of the Yellow River, and the heavy snow of the Changbai Mountain...... These glasses are imaged using a 3D structure, giving people an immersive feeling.

And it runs in a networked way, for example, there are 500 people in this scenic area, and everyone is wearing the same glasses as you, so you can communicate with each other, so that you can enjoy such a beautiful scenery or wonder from different angles. The premise is that someone else wants you to connect, and this is mainly a home app. For example, when mom and dad go on a trip, they can watch the sunrise and sunset with their children. Of course, if you are a travel expert, then you can use such glasses to attract more fans, and you can observe from one angle at the same time.

Of course, it also has one of the most important functions, which is to be able to see the situation on the scene at the first time in the event of a natural disaster. High-resolution satellites are used to observe the scene, and then when search and rescue personnel arrive at the scene, they can know the situation at the scene as soon as they arrive.

Another is to control the speed of light, electronic components control the size of the current, so as to control the transmission speed of light, so that when measuring the straight-line distance, the accuracy will be improved a lot. Of course, its light is not the same as the light in our nature, and it is also different from the light in Li Yaqin's laboratory. Sunlight travels in a straight line, but it does not follow a given direction, and it is impossible for a person to control its speed. Although the light in Li Yaqin's lab can control the direction, its principle is to reflect other images, and the speed cannot be controlled.

And the light he saw in the venue was the speed at which the beam could be seen by the human eye. In a special container, the staff operates the interface, you can see that the beam is slowly moving forward, the direction can be controlled, and the speed can also be controlled.

Of course, there is also something tailored for the main body of this competition, the home terminal control system. The theme of this competition is the Internet of Everything and the integration of cities, and some teams have made the integration of home Internet of Things. All household appliances are centrally controlled on a single terminal. In this way, on your way to work, the hot water has been boiled, the air conditioner has been turned on, and some simple work of steaming rice and making soup can be completed. It is different from our current timing function, which can be controlled at any time to prevent accidents, such as traffic jams, or receiving a call halfway to do something else.

Liquid metal, photoelectric sensing, material display...... He told Li Yaqin everything he saw and heard at the scene.

Seeing what he said with relish, the corners of Li Yaqin's mouth also raised a smile. She hasn't been a spectator for a long time, she's always been explaining to others, and it seems that she enjoys listening to it today.

When Lei Banfei was talking energetically, Li Yaqin asked, "How is your new equipment, is it still going well" Regarding his new set of equipment, Li Yaqin is still worried about it, although those do not belong to him, but they have also been upgraded by his own hands, and of course, there are those unknown things.

This question interrupted what he was about to say, "It's perfect, so I'm here to thank you today" Lei Banfei replied without thinking.

They walked up to the vending machine and said, "What a kindness, a drink or a drink"

"It's okay" In fact, Lei Banfei knew that he had grown so big and had never drunk alcohol, but the girl asked, can't he drink anything.

He took the beer handed over by Li Yaqin and asked, "I was unhappy to see you last time, so I ...... it."

"So you're here to comfort me today," Li Yaqin asked, it seemed that her mood was different from just now.

As soon as he heard this, Lei Banfei hurriedly explained, "No, no, I'm here mainly to see how your work is done, sister." You helped me so much last time, I'll come over and see if there is anything that can help you" He noticed that Li Yaqin didn't seem to mean to be angry.

"Okay, don't worry about me, how do you feel about this competition?" She also knew that she couldn't talk about these private emotional issues with Lei Banfei, so she had to talk about something else.

"Long insight, really long insight" As soon as he talked about this, he couldn't suppress the excitement in his heart.

"What do you think is the significance of this competition?" was asked very suddenly, and he was not the slightest bit defenseless, and was stunned. What does it mean, what is the meaning of the competition, Lei Banfei's expression is indescribable. "Don't be like this, I'll ask you what you think of this competition" Li Yaqin knew that the question just now was too profound, and quickly rounded the matter back.

"I think it's good, in addition to seeing new things, we can communicate more......" He really didn't know how to answer the latter words. He thought for a moment and said, "Actually, I've asked a few friends to visit my new lab tomorrow, sister, when will you come over." Haven't you always wanted to know the source of my energy body, and when the time comes, it can explain it to you" It seems that he has figured it out.

"Yes" Li Yaqin has always wanted to understand that inexplicable energy body, and of course she will not miss this opportunity.

"But the contest is already very close, sister, when are you and your work going to pass?"

"My work has been sent over this afternoon, there is nothing to do here, I will leave tomorrow morning, and I can go to you in the afternoon" It seems that Li Yaqin has arranged her own affairs properly.

"Did you drive there" I don't know if it was his first time driving last time or something else, he was interested in the car.

"Of course, isn't it possible for me to walk over, I don't have your equipment......" It seems that she is also quite envious of Ray-Ban Fei, although she also has her own private means of transportation, but she knows that the two cannot be compared.

"Your car is so good, especially those scene switches, it really feels like it's real, those starry sky, sunshine, breeze, ......, alas, how did that breeze come out, you say that images can deceive people's vision, but this wind is real" Lei Banfei told Li Yaqin with great interest about the experience of driving for the first time.

"The wind, it's very simple. The wind of the ordinary car air conditioner has a special air outlet, and it is one by one, have you noticed that there is no air outlet on the car, I hid those devices and made an air outlet belt, so that the wind blowing out you will not feel that it is a piece, you can feel it here, you can't feel it there, so it's like a natural wind......"

The two sat like this by the stream at Jiangning University, drinking and chatting. Chatting late, I was in a bit of a trance when I drank, at least Lei Banfei felt the same way, it seems that he is really not good at drinking.

But it's good, both of them have kept their senses, at least Li Yaqin thinks so. "It's not too early, you should go back early" She got up and prepared to leave. As she spoke, she could already see that Ray-Banfei's tongue seemed to be knotted when he spoke.

Although Lei Banfei is not good at drinking, but a can of beer is not enough to get him drunk, he also got up and patted his body, "When will you arrive tomorrow, I'll pick you up" He looked at Li Yaqin, and seemed to be a little nostalgic for such a scene.

"You don't have to pick me up, I'm going to have to meet our teachers and classmates first," she said, walking forward, leaving only a back for him.

"Didn't you just promise to visit my lab," Ray-Ban Fei asked, following behind.

"I'll pass later" She walked forward slowly, and Lei Banfei followed slowly, deliberately keeping a little distance.

Suddenly, Lei Banfei lowered his head and said softly, "Sister, you are so beautiful tonight" I don't know if it's because the wine is coming up or if it's the truth, anyway, it's just saying it.
