The whole hall, there are almost no other superfluous decorations, luxurious and rich at the same time, but also a little empty, it stands to reason that such a luxurious decoration, how can there be a lack of decorations, as well as chairs and coffee tables, how can one by one make such a low-level mistake.

It turns out that there are no design decorations and tables, chairs and sofas one by one, of course, the tables, chairs and sofas are standard, how can you forget it, it turns out that these tables, chairs and sofas are designed to be hidden one by one, as long as you shout at them one by one, he will show the hidden tables, chairs and sofas, of course, this is because one by one is showing off Liu Long's skills, otherwise when Liu Long enters the door, the tables, chairs and sofas have already appeared.

As for the decorations, Yiyi did not have a design, but hid multiple holographic projectors around the hall, and he replaced the single fixed decoration with a virtual and diversified decoration.

As the name suggests, virtual diversification is the use of holographic projection technology, the surrounding environment decoration can be laid out according to their own ideas, and there can be several or more sets of decoration schemes, and even according to their own mood at will, and you can add or reduce the virtual decoration in the hall at will, it can be said that it is not an exaggeration to do whatever you want.

Some people may say that what is fake is fake, how can the virtual be compared with the real thing, this sentence is not wrong, but it is also necessary to divide the items.

In fact, all decorations are for the eyes.

As we all know, vision is caused by light entering the transparent cornea, through which light is refracted to enter the pupil.

The size of the pupil is controlled by the iris, which is the colored part of our eyes, when the light is strong, such as in the sun, the iris narrows the pupil to prevent some strong light from entering the eye, and when the light is dark, such as in the cinema, the iris dilates the pupil to increase the light into the eye and make the vision clearer.

After the pupil, the light reaches the lens, which has the function of regulating vision, and the lens and the vitreous at the back have a refractive effect, focusing the light on the retina.

The retina is a thin layer of tissue, it contains thousands of rod-shaped and cone-shaped cells, the cone retinal cells can make the eye see clearly under the light, and can make the eye see color, the rod retinal cells can make our night vision better, and help our peripheral vision, the cone and rod retinal cells convert light into electrical waves, the visual meridian transmits these radio waves to the brain, and the brain converts these messages into images we see.

In layman's terms, the reason why the eye can see objects is because there is light, and if there is no light, then the human eye cannot see any object.

The function of ornaments is to make the eyes see comfortable, and the reason why the eyes can see is also because of the presence of light.

And holographic projection is to take advantage of this, as for whether he is a real thing, the EEG signal fed back to the brain by the eyes is the same, so it gives people the same feeling, or better.

And there are not a lot of physical decorations in the hall, which will make the hall more bright and spacious, which is also the requirement of many people for house decoration.

Therefore, the design of holographic projectors one by one to replace the physical decoration is absolutely ingenious.

The four old men looked at the splendid and empty hall, and all of them turned their puzzled eyes to Liu Long.

Liu Long, who was originally holding the two divine beasts, was still admiring the "masterpieces" of Yiyi, and after feeling the puzzled eyes of the old people, he put the two divine beasts on the ground, and shouted to the air, "Yiyi, show the tables, chairs and sofas, and then replace the environment with the decoration of the pastoral scenery of the northern country." ”

As soon as Liu Long finished speaking, the environment of the whole hall changed, and suddenly there were a lot of wooden products with a sense of age next to the wall, such as the wheelbarrow of the seventies and eighties, the board of the Republic of China, the manual stone mill, the manual spinning wheel for weaving, and some plows, rakes, and carts for farm work.

And on top of these tools, there are all kinds of harvest fruits, such as yellow corn, smiling and bent rice and wheat, red-skinned sweet potatoes, round and spherical potatoes, and the strings of blood-red peppers.

The hall lamp in the hall also has a unique style, because what catches your eye is the jack-o-lantern made of pumpkins, which are hung in an arc in rows on the roof, and in the middle position, there is a super jack-o-lantern weighing several hundred pounds, and these jack-o'-lanterns also have a common feature, that is, they are suspended on the roof, which brings a different visual feast to people's vision.

Of course, these are all mapped through holographic projection technology, but knowing that this is fake, everyone can't help but take a few more looks, and it can be seen that these virtual scenes and the visual feast shown are successful.

Everyone fell into a visual feast, and at this time, the two mischievous beasts woke everyone up, "Dad, didn't you say that there was dessert, and grandpa they are also tired, how did you do your son, and let them stand all the time." "The divine beast Liu Rui is like a little adult, walking back and forth on the ground with his hands behind his back.

Hearing the words of the baby son, and looking at the unkind eyes of the four old men, Liu Long hurriedly picked up Liu Rui and gave him a look not to talk nonsense, "Dad, don't patronize it, go over there and sit down first, and rest for a while." ”

"Xiaolong, these should be images mapped by holographic projection technology. Father Yi asked Liu Long as he walked.

"Dad, it seems that you really can't escape your insight, it can be said that this hall, except for the necessary tables, chairs and sofas, is all mapped through holographic projection. Liu Long said as he led the group to the sofa that appeared.

"Well, this style is really good, such a good holographic projection technology, it's a pity that you don't go to promote it. Sitting on the sofa and holding a jade teacup in his hand, Yi's father said casually.

"Isn't there no time. Liu Long blushed a little and found an excuse that was not an excuse.

Yes,Holographic projection technology is Liu Long for the space building housewarming ceremony and research and development,At the housewarming ceremony,After showing the magic of holographic projection,All the gods have been looking for space technology cooperation,After all, the holographic projector with mature technology,Relatively speaking, it is everyone's favorite money,And it is advanced technology,However, Liu Long did not agree at that time,Then he left the holographic projector behind,To be exact,Liu Long forgot the holographic projector。
