I was thrilled, imagining what this planet might look like. I thought it must be highly advanced in technology, surely bustling with prosperity. The streets would definitely be crowded, and lively with people coming and going. People must be dressed in the latest fashions, perhaps even in bizarre and unusual styles. The buildings must be beautiful, grand, and imposing, with all sorts of strange cars running about, maybe even cars flying through the air...
Would there be any major leader to welcome us, or perhaps some sort of public welcoming event?
We didn't walk out of the spaceship; rather, it felt like our bodies floated, and we left the ship, with the scenery changing dramatically before our eyes.
What appeared before me was not a welcoming party or the bustling streets of this planet's cities. I saw many flying saucers of different sizes on racks.
A few robots approached one flying saucer, likely the one we had just been in. I guessed this place might be a flying saucer warehouse.
Now, up close, I observed the exterior of the flying saucer we had been in. It was clearly made of metal, in a lead-gray color, seamless, with no windows, holes, or visible lights. How could it emit light outward?
When the flying saucer arrived on Earth, could it hover in the sky, and did people enter and exit from the bottom? Inside the saucer, there was a thick pillar, hollow in the middle, connected to the door at the bottom.
At that moment, the dull feeling in my brain disappeared, and my thoughts became as clear as they normally are, my spirits lifted.
I looked up carefully at the flying saucer warehouse, which was immensely huge, stretching beyond what the eye could see, and incredibly tall, about the height of dozens of buildings. The racks held many flying saucers, varying greatly in size.
Standing on the ground, I wondered about the materials used for the walls and roof of such a vast space.
I thought these materials might not exist on Earth, considering the enormity of the building, which seemed to span tens of kilometers without a single supporting column, a feat that seemed unbelievable.
Furthermore, standing there, I felt significantly heavier than on Earth, which was somewhat strenuous. I assumed the gravity on this planet must be stronger than Earth's, necessitating roofing materials of exceptional strength.
Looking up at the roof, I pondered what special materials were used for such a vast span in their warehouse.
The roof was too high for me to see clearly. I walked over to the warehouse walls and began to inspect them closely. I found the walls were soft, delicate yellow, very fine, and flawless.
I wondered, is it necessary for a wall to be this refined? Upon closer inspection, I found the walls resembled the bodies of the robots on the spaceship, made up of countless fine, tiny components that vibrated subtly. This vibration wasn't uniform but gave off a sense of disarray.
When I touched the wall, it felt hollow, and my hand seemed to be stopped by an invisible force. The further I pushed my hand in, the greater the resistance, similar to the repulsion felt when two magnets with the same poles are pushed together. However, this repulsive force felt much stronger than any ordinary magnet could produce.
"Could this wall be made of some kind of intangible material?" I wondered internally.
"Yes! This is a type of virtual construction generated by an artificial field, emanating from those tiny black objects at the bottom of the wall. These black objects are called artificial field generators. They emit two types of fields. One is a repulsive field that is symmetrical along a plane, opposite to the gravitational field on your Earth. It can push everything outward from its central plane.
The middle part of the plane is called a light-condensing field, which can solidify light from the outside within a certain spatial range. The yellow light you see is because the light-condensing field has chosen to solidify yellow light, omitting other colors.
We could also choose to solidify blue, red, green, or any other colors—it simply depends on the preferences of the designer.
"The light is collected from the surrounding environment. If it's nighttime, less light is collected, and you'll see the walls appear dimmer."
That mysterious, standard male voice appeared in my mind again (This time it didn't seem to come through my ears) and continued to explain to me. "You're smart to realize that both the walls and the roof are virtual, essentially just forms of energy existence. If the artificial field switch is pressed, the walls and the roof can immediately vanish without a trace.
If hit by an unexpected impact, these virtual walls and roofs can withstand the blow, their strength far surpassing that of real walls and roofs. However, there is still a limit.
Should the speed and force of the impact exceed a certain threshold, an object can still penetrate and cause damage inside the virtual building. This also depends on the strength we've designed, which, clearly, is directly proportional to energy.
You might find this strange, but our planet is, in fact, highly virtualized."
I hadn't anticipated that upon setting foot on this planet, the first marvel I'd encounter would be virtual walls.
