After Wang Qianyu walked out of the laboratory, Tang Yuhang sat on a chair and threw a piece of chewing gum into his mouth, "Source, you also heard it, it seems that you can only do satellite networks now." ”

"Yes, I heard that." The source replied, "Need to make a hidden satellite?" ”

"No, it's too troublesome...... Tang Yuhang shook his head, "This will be made by the space factory at that time, Yuan, your task is very important, and you must ensure smooth communication between the earth and the space factory when the time comes." ”

"This is still very difficult at the moment, after all, the space factory is very large, and you want to put it behind the moon to ensure secrecy, the distance between the earth and the moon is 380,000 kilometers, and the space factory cannot be solved with a satellite network."

"That's a problem...... Tang Yuhang nodded, "It seems that a large repeater is still needed, right?" ”

"Yes!" Yuan replied, "You need a high-power repeater to keep the network running smoothly so that I can control the space factory at all times." ”

"The question is how?" Tang Yuhang took a sip of his coffee cup, "The speed of light is 300,000 kilometers per second, and the distance between the earth and the moon is 380,000 kilometers, if you use light to conduct signals, it will take more than a second, which is too slow......"

"It's slow indeed!" Yuan replied, "But you also said just now, quantum communication can't be done in this era, do you have any ideas?" ”

"Wait, I want to think about it......" Tang Yuhang sat on the chair, temporarily putting his consciousness into the biochip, checking if there was anything to replace.

Gen agreed, and waited quietly.

After about ten minutes, Tang Yuhang raised his head and showed a smile, "Yuan, what do you think if you use high-speed particle light waves?" ”

"I haven't been involved in any of these experiments, I don't have any experimental data here," the source replied, "and I think you need to try to do an experiment." ”

"Experiments? It must be possible......" Tang Yuhang said with a smile, after all, this thing has been verified countless times in the future, as long as you don't change it casually, of course you can.

Scientific research is not the same as martial arts and other sports.

Whether it's martial arts or dance, if a person who hasn't practiced before, even if you can follow a master and imitate all the movements of the other party, you still can't reach that strength or feeling.

But scientific research is different, for example, if a person makes an electric fan, even if a person who does not understand scientific research at all, as long as he follows the steps of the other party step by step, then he can also make an electric fan.

This is technology, as long as every step is correct, even if you don't understand many of the principles, you can replicate them completely.

What's more, the technology in the biochip will explain all the principles clearly, which can completely allow Tang Yuhang to learn independently.

"Rice! Little clumsy hands! Tang Yuhang stood up and shouted, took off his coat and threw it on the chair, "Prepare tools!" Let's make a super repeater......"

……………………

On the other side, the No. 32 bus from Yushan to the city center stopped in front of the platform, and a girl wearing a white T-shirt, denim hot pants, and sneakers walked on the bus.

With long hair tied in a ponytail, and fair skin, the attention of the few people on the bus was unconsciously attracted, but the bus driver was startled, and the girl's two eyes were actually red.

The girl took the change from her pocket, threw in the coin, and then walked into the carriage, not sitting in any empty seat, but standing not far from the back door.

Seeing the girl standing there expressionlessly, the driver also turned his head and breathed a sigh of relief, thinking that maybe it was a contact lens, shook his head, closed the door and started the car, and drove to the next platform.

Due to the geographical environment, there are few horizontal and vertical roads in Yushan, and most of the roads are winding, so only the place close to the city center will be better.

The bus is naturally wobbly, there are not many people on the bus at this time, there are many empty seats, but the few people on the bus are basically looking at the beautiful woman standing next to the back door.

When I first came up, someone saw those red eyes, but in this era of endless appearance of various types of contact lenses, no one thought about it in other directions at first.

But when the bus started and saw that the beautiful woman was not sitting down at all, but standing, many people unconsciously focused their attention there.

Especially now that the bus is shaking, the other party's hands are still hanging on both sides of the body. The feet were motionless as if they had been rooted. Standing firmly in the rickety carriage, there was no sign of falling.

When Tang Yuhang set up the robot program, he considered this problem, and the robot may not be slower than the car when it runs with full energy, but the problem is that the energy consumption is too large, so the robot will also take the bus in the absence of an emergency.

Of course, even in Tang Yuhang's eyes, robots have the most basic rights and interests protection, and robots can't be allowed to compete for seats with humans, so robots can't sit on the bus.

A young man stared at the red pupils, and the other people in the car were also discussing that there was always a feeling that something was wrong with the girl, and she stood there motionless, always feeling like a dead person.

"No, it's a robot!" A young man seemed to suddenly think of something, interrupting everyone's discussion, "Robots of future technology!" ”

"Robots?" The other people in the car were stunned for a moment, then looked at the red pupils who were still standing there motionless, and even the driver raised his head to look in the rearview mirror.

Not to mention, the more you look at it, the more it looks like it. If you were a human, you would feel uncomfortable being stared at by other people, but robots don't feel that way.

The robot that seemed to have discovered a new continent stood up from its seat, grabbed the armrest and slowly walked to the side of the red pupil, and lifted his glasses, "Hello, hello this beauty......"

Red Pupil turned her head and asked expressionlessly, "Are you talking to me?" ”

"That's right!" The young man looked at the red pupils and nodded, "That'...... I don't mean anything else...... I'm just asking, are you a robot? ”

"Yes!" Red Hitomi replied, "I'm the female version of the dear I-type robot made by Future Technology. ”

"Wow-", the passengers sitting in the back were all shocked, although the news has been reporting that the sales of robots are very hot in the past few days, but they never expected to see one so soon.

The driver who is driving is also looking at the front half of his attention, and the other half is looking at the rearview mirror while listening to the sound behind him.

"That ......," the young man was a little excited, "why are you doing the bus here?" ”

"The master went to work, and I went to the supermarket to buy vegetables and cook for the master." After judging that this is not confidential information, the red pupil answered honestly.

"You...... Going to the supermarket to buy groceries by yourself? The young man asked incredulously, "What if I find the wrong money?" ”

"I have a calculator function in my body, so I can't make a mistake." The red pupil replied, "Numbers below 100 billion are 100 percent correct. ”

"Forehead......" The young man felt a burst of embarrassment, just at this time the prompt that he was about to arrive at the station sounded, the young man was his own station, showed an embarrassed and polite smile, and got off as soon as the door opened.

No one else in the car came to talk to Red Pupil anymore, just looked at her from a distance, and some took out their mobile phones to take pictures.

After arriving in the city center, Red Hitomi got out of the car and walked to the side of the road. When the red light time arrives, cross the road through the zebra crossing.

After confirming that the owner is activated, each robot will connect to the network to download the map of the city where it is located, as well as the information of all buses, subways and other lines, so there is no need to worry about getting lost.

After entering the supermarket, the red pupil did not push the shopping cart, but took a shopping basket and went in, and the power of the robot would definitely not be unable to hold it.

A beautiful woman will be attractive anywhere, and now there are a lot of people in the supermarket, and soon someone noticed this beautiful woman with a somewhat strange behavior.

Ordinary people always look east and west when they go to the supermarket, and people like Xiang Hongtong who do not squint are rare in the supermarket, so they naturally look a little weird.

When I saw those red pupils, many people had already discovered that this might be the dear robot that had been in the news recently.

More and more people have found it, and many of them have already followed the red pupil, but there is no special meaning, purely with a sense of curiosity.

Soon the security guard of the supermarket also found out about this problem, and when he came to look, many people were following a beautiful woman, and then the beautiful woman stopped in the vegetable section and began to pick and choose to put vegetables in the shopping basket.

Then there was a group of people watching from the side, and then took their mobile phones to record videos, and there were bold and blatant people who ran to the opposite side of the red pupil to record, and many people also began to talk about it.

"This is the kind of robot that has been on the news lately, right?"

"I look like it, you see the eyes are red."

"Speaking of which, although it only started to be sold in the early hours of yesterday morning, the future technology is in our Yushan, so the locals should receive the goods quickly."

"Didn't you see someone like your master, did you come by yourself?"

"Wouldn't it? That's too smart, isn't it? ”

……

Regardless of the other people's discussions, Red Hitomi picked up some vegetables and walked to the meat stall.

The meat stall owner was sharpening his knife when he saw a girl with red eyes and a group of people walking towards his stall.

"I'll ...... Collecting protection money? The stall owner muttered to himself, then stood up and looked at the red pupil and said, "Need ...... Need something? ”

Red Pupil looked at the price next to him, "I want half a pound of pork belly." ”

"Forehead......" The stall owner was stunned for a moment, nodded and said, "Okay!" As he spoke, he took the pork belly next to him and began to cut the meat.

A person next to him came over and whispered, "This is a robot of future technology, you give her a little less to try." ”

The stall owner looked at the expressionless robot in front of him and nodded silently.
