Qin Guangyue, along with many delegates, was pulled to Yunze Lake by the bus.

Then he was guided by two employees of Shengshi Technology and walked up to the dam by the lake.

It was already completely dark.

Although it is already late October, in Xidu, a city with little temperature difference all year round, standing by the lake, there is no cold feeling, and the breeze blowing from the lake is cool and fresh.

Listening to the sound of the lake crashing against the embankment, the delegates looked at each other. There are no buildings except for the lake, the embankment, the parking lot and the woods next to it. If you were to have a party, it seemed that there was really no place for these hundreds of people to sit, and there was no stage.

Looking across the lake, you can vaguely see a strip of light composed of street lamps on the highway at the foot of the opposite mountain, and some people guess that this stage is in the lake.

Qin Guangyue pouted, this Shengshi technology is really kind of enough, and he actually planned to let so many bigwigs stand and watch the performance.

At this moment, there was a slight noise in the lake, and the show began.

Everyone looked into the lake, and Qin Guangyue also looked at the lake intently.

I saw a large area of the lake turn white, as if something white was rising. The object was getting closer and closer to the water, getting closer and closer. Eventually, there was a 'whoa' and surfaced.

Someone exclaimed, and a large milky white disc floated on the water, and the disc did not appear to glow, but was only made of white material. But in the starlight, one can see the object very clearly, as if there is a light shining on it.

There were a lot of seats on the disc that were also white, and it turned out that they were the seats for the evening show.

A road of the same material rose in the middle of the lake, and when it was almost as high as the dam where everyone was standing, the guardrail of the dam opposite the road was lowered, and a road leading to the disc appeared before everyone's eyes.

One of the two Shengshi Technology employees standing on that road was doing the operation of inviting and embarked on the road that looked like it was made of white marble.

When the employee stood on both feet, it was like riding an escalator, and he walked forward, not fast, and it was about the same as walking.

The other one is there, slow down, and when you stand on your feet, you'll move forward.

Someone tried to stand up, and then went on steadily.

Someone kept standing up and walking forward.

Qin Guangyue found that the people standing on it were very strange, they didn't look ahead, they didn't look left and right, they all lowered their heads, as if they were looking at the road.

Others did not stand on the middle pavement, but tried to stand on the shoulder of the pavement that was raised next to it. When you stand on it, you don't go on automatically, but the person who stands on it takes a step forward by himself.

The shoulders on both sides of the road are 60 centimeters wide and have no guardrails. The man walked a few steps, perhaps fearing that he would accidentally fall into the lake, and stood again.

Qin Guangyue also walked along the road with the gradually moving flow of people. Walking to the side of the road, he took a closer look, and the road surface could not be seen moving. Unlike the moving sidewalks that are common in shopping malls and supermarkets, it is easy to see that the entire road surface is moving when compared with the fixed parts next to it.

Qin Guangyue glanced at it a few times, the road was really not moving, and he had doubts. I stretched out one foot and stepped on the road, and I really didn't feel the slightest movement.

The female employee of Shengshi next to him explained to him: "You can only move when you step on both feet." ”

Qin Guangyue felt that his face was a little burning, and the others naturally walked up and went forward, only he tried cautiously here.

He hurriedly stepped his other foot up as well.

Sure enough, both feet stood up and moved forward. But this kind of movement is not the same as the escalator or moving walk.

Qin Guangyue couldn't help but lower his head and study the road below.

The pavement didn't move, absolutely didn't move, it was just that his feet were moving.

Of course, the feet don't move on their own, it's the part of the road that moves.

This kind of technology seems to be very good, Qin Guangyue has been to many places for most of his life, and he has been to various high-end places abroad.

But I have never seen such a road surface, the feet do not move, the road surface does not move, but the people, they go forward.

Qin Guangyue tried to lift his right foot slightly, he was still moving forward, and then he took the right foot he lifted diagonally and stepped on the curb of the road. Yo, there was a movement, and the left foot, which was originally moving, did not move.

Qin Guangyue watched as he stood still with his right foot on top and his left foot on the bottom, getting farther and farther away from the person in front of him.

He took his right foot into the road again before he stood firm and moved forward again.

Strange, really strange! Qin Guangyue lifted his right foot again, intending to try again.

Someone behind him said something in bird language, Qin Guangyue reacted, he stopped again, and the people behind him might bump into him. Hurriedly stood up, and with the movement of his feet, he went to the big disc.

Qin Guangyue moved to the disc, and the path of his feet stopped moving. He took a few steps forward and found a slightly backward position to sit down.

Before sitting down, he was worried that the chair was wet, so he deliberately touched it with his hand, but fortunately, it was very dry, not like it had only risen from the water. And the chair is not cold, but warm, like someone sitting at the temperature when they just got up.

This chair seems to be made of the same material as the disc under its feet, and it looks like it is one. Qin Guangyue was also worried about whether it would be uncomfortable to be hard, but when he sat down, it turned out to be soft. It's the kind of soft that has a certain amount of support and a certain amount of deformation, and it is very comfortable to sit on.

When he first touched it, he didn't notice that the chair was soft, so after he sat down, he curiously groped around. After fumbling for a long time, he summed it up, his hand was just on the top, and he couldn't feel any deformation, but if you pushed hard, the seat would soften a little. This is true for the back of the chair, the seat, the armrests.

It's strange, it's really strange! Qin Guangyue sighed.

Behind Qin Guangyue, Mark also felt the magic of this 'self-moving road', which was the name that Mark temporarily gave to this road. He wondered how this was done, and the man stood up and began to move. This movement, Mark confirmed that only a small piece under his feet was moving, like a boat moving on water, sliding.

This Shengshi technology is really amazing, on this road, Mark feels that if he is allowed to develop it, it may not be possible to achieve it in ten or twenty years.

Automatic control is a difficult point, looking at the Oriental people's attempts in front, lifting the foot does not stop, but as soon as there is a step, it stops.

And that kind of material, it is quite difficult to achieve. It looks like a whole thing, but it should be made up of very small scattered parts, so that it is possible for some parts to move away from the others without people feeling it at all.

And before that part moves, the other parts immediately move over and fill in the position of that part.

How does this material bear weight? What about the powertrain underneath it? How is it driven? How to recognize a person's movements? ……

When you think about it, there are too many questions. The material is amazing, and so is the control method. What's even harder is that moving makes people feel that some of them are moving. Also, the way rises out of the water.

Mark shook his head in thought, just this way, I don't know how much scientists' efforts were spent to develop. Just this short road of five or six hundred meters, I don't know how much it will cost to pile up, to build.

It doesn't seem to be of much use to develop a way out in this way. More of it, as a gimmick. Mark thought.

At the end of the road, Mark also walked a few steps and found a seat to sit down. These seats are very far apart, and there is only one between the rows, but between the rows, you can also easily walk past a fat man when someone is sitting, and at least one chair position is vacated.

It's uneconomical, Mark commented. The only good thing should be that everyone can sit in any chair without bothering everyone else.

As the people who came to the party gradually sat down, a row of transparent round pipes rose in front of them, which were facing straight to the sky, and there were horns at the highest point, and it could be seen that the middle was obviously empty.

These tubes, one after the other, are close to each other, and the lower cylindrical part is slightly detached.

The row of tubes looked a little thicker than a tennis ball, about four meters high when it came out of the water, and about five or six meters away from the whole disc on which Mark and the others were sitting, was facing Mark's seat, and it was distributed in an arc, and the arc should be the same as the arc of the disc on which they were sitting. And so it stretched out of the lake.

What is this for? Mark looked at the cylinders puzzled.

He just looked at the round pipe, but he didn't notice when a lot of people were rising behind him, and those people were all employees of Shengshi Technology, all wearing uniform dark green uniforms. It stands very tightly and is also distributed in an arc of the same radian.

Where did these people come from? Also rising from the water? Mark wondered.

The Shengshi employees were almost six or seven meters away from those round pipes, because they were far away, and Mark couldn't quite estimate the exact distance. And the person in front of him is blocking the view, which is not very good-looking.

There are five rows of Shengshi employees, standing in a stepped manner, and the back one is a little higher than the front. Beside them, there rose some columns containing colored balls, which glowed faintly and softly, like the kind of light emitted by fireflies.

Mark heard a female voice say: "Please enjoy the show performed by 550 employees of Shengshi Technology: throwing small balls." Seat adjustment is about to be made, so please sit back and be safe. ”

The female voice was close, as if it were in Mark's ear, speaking in English.

As soon as he finished speaking, Mark felt himself rise, and in a blink of an eye, the twenty rows of seats on the disc became a stepped type, like the seats in a movie theater, and his vision widened.

Mark could be sure that he had never seen the gap before, and that the disc was a single piece.

He turned slightly, leaning down to take a closer look at the seams in the floor, which had been flat before, but now stepped up.

But there were no seams at all, and when it was raised, it was still integrated, as if carved out of a single stone.

I was amazed by Mark's admiration, and the material science of Shengshi Technology was really remarkable.

He looked up and saw several small balls falling from the row of tubes in front of him, and he quickly asked the person next to him what was going on.

The man next to him also spoke English, and the man told him, "They threw it so accurately." ”

Did you throw it accurately?

Mark didn't know why.

Suddenly, music played.

With the music, the employees of Shengshi Technology, who were six or seven meters away from the row of round pipes, began to pick up the small balls around them and threw them.

As soon as he threw it, Mark sighed, and threw it accurately.

Those Shengshi employees are really accurate. Although they stood tall and threw it from a high place to a low place, they were six or seven meters away, and such a small ball, a pipe slightly larger than the ball, they threw it into the pipe without being empty. The bell mouth of the round pipe is not much bigger than the ball.

They didn't hesitate at all, they didn't skew at all, they kept throwing it, everyone kept throwing it.

Take the ball in your left hand, hand it to your right hand, and throw it with your right hand. Every Shengshi employee standing on the high platform has been repeating such actions with a very high frequency.

In the beginning, they threw solid-colored balls, all of which were green.

As they kept throwing, the balls kept falling down the tube. Slowly, the balls filled the entire tube, and while the balls kept falling, new balls kept coming in.

The whole row of pipes turned out to be a curved green wall.

Throwing and throwing, small balls of other colors began to appear.

Mark suddenly realizes that this is not a wall, but a screen.

A screen of falling balls thrown by a person.

A small ball is a pixel.

As the color of the ball changed, a picture of primitive man hunting an elephant appeared, which slowly moved from top to bottom and then disappeared from below.

Then, knotted rope notes, all kinds of pictographs slowly appeared, and then pictures of all kinds of people doing various things appeared, geocentric models, engravings, atomic models, etc., Newton appeared, Einstein appeared.

All kinds of things, people, and events appear like flowing water on this screen made up of small balls. Then, it flowed away again.

It's like they appear in the long river of history and then disappear.

Mark understood that the employees of Shengshi Technology were telling the history of human science with their hands.

Mark was so surprised, can people do it to this extent? Are the employees of Shengshi Technology made of any special materials?

Mark looked at it for so long and didn't see any employee who threw the ball away. This is not a cylinder in front of him, but a very thin tube six or seven meters away.

The ratio of the ball to the diameter at the maximum point of the bell mouth of the round pipe is definitely less than the ratio of the basketball to the basket. And the distance, the distance is about the same as the three-point shot. It's much harder to throw this ball than it is to shoot a three-point shot.

They threw so many at such a high frequency and none of them, that is, a 100 percent hit rate.

How did you achieve such a high hit rate? If they go to a competition that requires accuracy, is it necessary for others to participate? Like shooting, even basketball.

There's another thing that no one else can't do, timing. Their ability to control timings is something no one else can do.

They threw the balls at a very high frequency, and the balls, when they fell in the same row, all looked like they were in a straight line. Even if the visual error of the eyes is excluded, the actual error will never exceed five millimeters.

There are five people in each column, that is, five people are in charge of each pipe. Look at their frequency, two or three balls are thrown in one second, even if it is two, five people throw ten balls in one second, that is one in a hundred milliseconds.

A hundred milliseconds, different distances, different positions, a little inaccurate, there will be the problem of balls clashing with each other, but look at how many they throw, the balls are one after another, and there is no collision.

Before they even reached the mouth of the tube, the balls were connected in the air in a line.

These employees are much more powerful than those machines on the automated assembly line. Such employees, Mark believes, can make the parts that can be made by the smartest machine tools by hand.

The more Mark thought about it, the more shocked he became, there were more than 500 employees with such a powerful staff, no wonder Shengshi Technology could be so powerful.

Mark thought again, it's been almost an hour since the beginning, and they've been repeating the same action at the same frequency, won't they get tired?
