As He Liuqing pressed the button, countless blue rays of light shot into the air from the holographic projector.

It was shooting in all directions, up and down, left and right.

It lasted about ten seconds, and then it shrank back sharply.

Immediately after that, various colors flashed on the originally black holographic projector.

"Isn't this really the spherical light in the discotheque?" he wondered.

Now it's time for the music, and it's time to jump.

"You think Fang Yuan is just like you, so unreliable?" the second uncle scolded beside him.

"Dad, I'm talking about playing. He Weiyang said with a smile.

But there was a muttering in his heart, you don't have much contact with Fang Yuan, how do you know if he is reliable?

Not to mention He Weiyang, in fact, the other people present also muttered in their hearts.

However, Lan Tianheng, who had seen Fang Yuan's use, knew that this thing was real, so he said to He Liuqing next to him: "Isn't the use method wrong, why don't you call and ask again?"

When He Liuqing heard this, he was just about to call Fang Yuan again, and the holographic projector moved again.

This time, the light spread out in all directions like a stream of water.

Then they ended up on a sandy beach.

"Damn. He Weiyang exclaimed.

He Zihao and He Zixuan, the two children, were even more frightened and hurriedly grabbed their mothers beside them.

The old man was so frightened that he stumbled, but fortunately, the uncle next to him helped him in time.

"Dad, it's okay, it's all projection. ”

Seeing that a large family was by his side, the old man was relieved, and he was really taken aback just now.

"Is this a fairy spell?" the old man only looked around at this time.

Blue sky, sparkling sea, seagulls soaring in the sky, golden sand .......

It feels incredibly real.

It was as if they had traveled through time and space and really came to the beach.

"It's been a long time since I've come to see the sea. The old man sighed as he stared at the sea in the distance.

The uncle was a little worried, but he still supported him.

Others were cautious explorers in all directions.

They swept the sand from the beach with their feet, and it kicked up a puff of dust, which then dissipated into the air.

He Zihao and He Zixuan also cautiously observed around.

They saw colorful shells on the beach, so they bent down to pick them up, but their fingers ran through them and they couldn't pick them up.

"Amazing, really amazing, what's the difference between this and the fairy spells in mythical stories?" the old man sighed.

"This is the power of science and technology, and many things are not immortal spells to the ancients now?" said the second uncle with a smile next to him.

In the distance, several women came to the beach, carefully touching the water.

There were countless splashes, but there was no sense of weightlessness of buoyancy.

"Old man. Suddenly, everyone heard a cute child's voice shouting in the distance.

Everyone followed the children's sound and looked at the sea.

I saw a little girl, stepping on the sea, running towards them, and every time she landed, there were layers of ripples on the surface of the sea, like a fairy.

"Shin Shin. The old man also spotted him and waved at her.

This little fairy is not just a little guy, she is followed by Fang Yuan and Lan Caiyi.

He also stepped on the surface of the sea, but as if he was stepping on the ground, he slowly walked towards them.

But their speed is the same, which gives people a very weird feeling.

"Shin Shin. He Zixuan rushed out of the crowd and greeted him.

But when he got close to the water, he carefully tested it with his feet, and found that the splash passed by, and the sea water covered the surface of his feet, and he had a feeling of being down-to-earth.

So they ran towards each other.

"Zixuan, don't run around. Although he knew that they were still at home, his mother Yu Shiyu still shouted worriedly.

"These are all fakes, are you serious?" He Weiyang said with a smile next to him.

But as soon as he finished speaking, He Zixuan, who was not far away, rushed forward.

"Zixuan?" Now Zi He Weiyang was also worried.

He Xiangrong ran forward directly.

He Zixuan himself was also startled, then reached out and pinched it on the sea, and finally got up, sat on the sea, and laughed: "It turned out that the sofa tripped me over!"

Everyone suddenly realized that it was the sofa at home, but it was even more surprising that the scene was real.

"Brother Zixuan. At this time, Xinxin had already run to him and circled around him.

"Sister Xinxin. He Zixuan stretched out his hand to pull her, but his palm passed through the other party's palm.

"It's Daddy's magic, you can't pull me. The little one smiled happily.

Then he ran out of the sea, on the beach, to the old man's side.

"Old man. The little one threw himself into his arms, but he was empty.

Then she stumbled and almost fell, and then she felt that someone was pulling her body, and when she looked back, it turned out that her father was holding her.

In fact, in the basement of Fang Yuan's house, the little guy just kept running in place, only moving the scenery, so whether he ran or walked, the speed depended on how fast the scenery moved.

This is also the weirdness that everyone just now felt that the little guy was obviously running again, Fang Yuan and Lan Caiyi were walking, but they maintained the same speed.

"Grandfather, uncle, second uncle....... Fang Yuan and Lan Caiyi shouted in a big circle.

The only person Fang Yuan didn't know was He Xiangrong's family.

But soon everyone introduced him to him.

"Fang Yuan, this thing of yours is really powerful, too real, just like the illusion in ancient myths and stories. ”

The old man watched the three little ones pick up shells on the beach, and although they wore them every time, they were very happy and laughed very happily.

"Grandpa, I just got this thing out, it's quite rough, and many details need to be optimized. Fang Yuan said with a smile.

"Isn't that rough? I think it's good. The old man hadn't spoken yet, but He Weiyang took over the conversation beside him.

"Don't you notice that there is no sound on such a large sea? and there is no feeling of the sea breeze. Fang Yuan explained.

Everyone was a little stunned when they heard this, because they were so shocked just now, everyone didn't notice this detail, it was indeed too quiet.

Not only is the sea quiet, but the seagulls soaring in the sky have not made a sound at all, and now that it has been said, it really feels quite weird.

"But it shouldn't be a hassle to get it, just add a few speakers and blowers, right?" Xiao Lin said next to him.

She took her son to Disney and did a project called "Flying the Horizon", in which people are suspended in the air with a spherical screen under their feet, and then through the surrounding speakers and the built-in air and water outlet devices on the chairs, people feel a real sense of flying the world.

"Yes, but this limits the use scenario, so in order to prepare for an air transmission, in fact, this function has been realized as early as abroad, that is, the principle that the sound communicator will be absorbed by light in the process ....... ”

"Okay, don't say any more, I don't understand the old man, but can this scene change the other way?" the old man interrupted him.

"Of course, on the remote control that I sent to my grandfather, there are eight buttons, in addition to the open and move keys, the remaining six keys correspond to six scenes.

This sea belongs to the No. 1 scene, if my grandfather is tired of watching the next six scenes, I can remotely help you load a new scene ....... ”

Fang Yuan took out a tablet, this tablet can remotely manage the holographic projection system, and naturally it can also load various scenes.

The scenes that Fang Yuan is using now are all captured through the Internet, and of course they are certainly not formal channels.

Most of them come from within some film and television post-production companies, especially some foreign special effects teams, and they store a large number of 3D scenes in their servers.

There are real scenes, there are illusory ones, he can use them directly to deal with them, which is very convenient.

"Say something I don't understand. The old man muttered quietly.

But everyone actually heard it and laughed.

Fang Yuan also smiled and clicked on the tablet in his hand.

Immediately, the light began to surge, and countless lines intertwined in the void.

Frightened, the three little ones immediately ran back to their mother's side and hid in their arms, but they couldn't help but peek.

But now they were not on the beach, but in a field of golden wheat.

This wheat field is not on the plain, but on the hillside, and you can see the houses, trees, and rolling hills in the distance, like a vast paradise.

"Wheat. The old man reached out and stroked the ears of wheat, and the palm of his hand passed through it.

The little ones also tugged at the ears of wheat curiously, and passed by in the same way.

But He Zihao and He Zixuan soon found out that it was different, their sister was different from them, and their sister really dragged the ears of wheat.

At this moment, they immediately shouted and screamed, which also attracted the attention of the adults.

"What's going on?" Lan Tianheng asked in surprise.

Everyone looked at Fang Yuan and waited for him to explain.

"I call this holographic complementation, for you, you are the entity, and the scene is the virtual scene.

But in fact, we are also a virtual scene, and the holographic projector transmits our influence to you through a remote network.

So there is a make-up function here, such as the action of pulling the wheat just now.

In fact, on our side, it also penetrates the ears of wheat, but when this action is transmitted to your side, the holographic projector will optimize this action and distort the image of the ear of wheat. Fang Yuan said, using his hand to make a motion to separate the wheat field in front of him.

Sure enough, in the eyes of the old man, the wheat was separated, and on the basement side, Fang Yuan's palm actually passed through the wheat.

In the same way, the old man's action of stroking the wheat just now, in his own opinion, was passing through his palm, but for the other party, he saw the ears of wheat swaying with his palm.

This is also Fang Yuan, they walked from the sea just now, and the sea water is under their feet.

And when He Zixuan ran into the sea, the sea water was on his feet.

Picking up shells should have been the same, but they were in the wrong position, their little fingers were together, and this action was judged to be crushed, so they felt that they had passed through.

If they could leave some gaps in their fingers, maybe the would help them do it, so that they both picked up the shells in each other's eyes.

Although everyone heard it in a fog, the general meaning was clear.

After Fang Yuan finished speaking, he clicked on the tablet again.

This time, they appeared at the bottom of the sea, surrounded by countless schools of fish.

Fang Yuan reached out and grabbed a clownfish, on Fang Yuan's side, the fish was passed through by Fang Yuan's palm, and then disappeared and reorganized.

But in the eyes of the old man, they saw a clownfish that was caught, and soon struggled to swim away.

"Fang Yuan, change it again, although this seabed is beautiful, it is quite depressing. He Liuqing looked around and said.

So Fang Yuan changed the scene again.

This time in a scenic park.

With the mental preparation of the previous times, everyone didn't feel any more frightened, and the rest were curious.

"Is this scene all fixed?" the old man looked at it happily for a while, a little dissatisfied.

"Of course you can move, I have set up a total of three modes, one is to move in place by binding the person, one is through the remote control, and the last one is to move the image at a uniform speed by itself.

However, because the function is not very perfect, it is easy to move through the mold. Fang Yuan said and clicked on the tablet.

Then the scenery of the park began to move, and although everyone stood still, the large trees and grass automatically collided with each other, which looked quite scary, and after moving, all the furniture that had been covered by trees and grass was also revealed.

The park and the home form a strange junction.

"The holographic projector is an airborne image, so when you block it and then move it, it will become like this, and if you hang it high, from the top down, there will be no such problem. Fang Yuan explained.

Everyone was a little stunned when they heard this, and let the holographic projection behind them, and sure enough, the surrounding scene soon changed into the appearance of a park again.

"Grandpa, when I finish moving, you can sit at home and travel the world. Fang Yuan said to the old man with a smile.

"Good, good. The old man applauded excitedly when he heard this.

At his age, there are not many places to go, and now he can travel the world while sitting at home, which is so happy.

"I'm afraid you can not only travel around the world, but also travel around the universe, movies and television, right?" the second uncle thought for a while.

This principle is a 3D scene, so naturally it can't just be a real scene, there are many virtual scenes.

"The second uncle is right, like this. Fang Yuan clicked on the flat screen.

In front of everyone's eyes, there are four big pillars in front of them, and there is a plaque above, with four big characters of "Nantianmen" written on it.

Look at the sea of clouds rolling under your feet.

"It's really a fairy trick. The old man was dumbfounded.

"Wow, marshmallow. The little one stuck out his little tongue and gently licked a cloud.

"Uh...... No taste, not good times. The little guy said with a little frown.

When everyone heard this, they were amused by her and laughed.

"Another example is the dream of the little one. Fang Yuan clicked on the tablet again.

Then everyone came to a fantastic world of candy.

This is the "Sweet Rush" world where Winelope lives in one of Disney's animations, The Invincible Wrecking King.

This world is very much in line with that dream of the little one.

It's a world of candy, everything is made of candy, lollipop trees, chocolate bogs, jelly hills, etc., plus bright colors, it's simply the perfect world for little girls.

Sure enough, the little guy was like a little dog, groping and licking everywhere.

Of course, she touches and licks air, but she still enjoys it.

Everyone laughed again at her small appearance, but Fang Yuan and Lan Caiyi covered their faces and felt ashamed to death.
