Wave refers to the propagation of vibration, take the rope jitter as an example, the rope shakes into a wavy line, there is a convex line that bends upwards is the 'crest', and a downward bending concave line is the 'trough', any point on the wave rope is selected for observation, and the crest and trough of the wave are constantly moving forward from the overall view, while any 'observation point' selected by the rope only moves up and down and does not move forward.

If there is another wave with the opposite peak and trough, the two waves will be neutralized and disappear when they meet, because they have canceled each other out.

After understanding the microwave frequency information released in the laboratory, they will create anti-frequency microwaves in a targeted manner, and the two microwaves will be canceled out invisibly when they meet, and the roots of exploration can go deep into the place guarded by the laboratory defense mechanism.

After traveling a distance of more than twenty meters, bypassing some obstacles, the roots of the gatherer came into contact with an enclosed area within the ruins, which was the source of microwave radiation, with microwaves radiating outward at 360 degrees from here.

The area of this unknown area is not very large, about 25 square meters, there are no gaps, no doors, and no traces of splicing, as if it was created as a natural whole.

"To do that, you need to do at least the molecular level."

"It's a good thing that the manufacturing process doesn't reach the atomic level, otherwise we wouldn't have been able to get in."

One of the collectors sighed with joy that although the enclosed area was made into a completely enclosed state, not even a single crack could be found, as long as it was still confined to the chemical plane, the collector could use chemical coordination to etch a hole in its natural surface and invade the interior.

"But if the manufacturing process at the atomic level is reached, the microwave defense may not be as good as it is now, and the microscopic particles closely arranged together form a degenerate material, that is, a complete atomic nucleus, and even if the microwave penetrates from the inside, there will be a great attenuation."

If that material is used to build this area, although the collectors have a way to invade, it will not be as easy as it is now, after all, the neutron explosion caused by the neutron degeneracy state being broken by an external force and the subsequent chain reaction are more terrifying than hydrogen bombs of the same volume.

The roots go deep into the interior, because there is no illumination, the visible light band is the same as the outside of the area, it is still dim, but in the low frequency band, the electromagnetic wave range is much brighter than the outside area.

Microwaves are also electromagnetic waves, but they belong to low frequencies, and now the perspective of collectors is to receive low-frequency electromagnetic waves, so it is natural to use the microwaves of the defense mechanism as visible light.

"Huh? What's going on...... It's impossible! ”

"What really exists cannot be lost because of doubt."

"But, but how did those Hui people achieve this effect? It's simply against physics. ”

"Existence is reasonable, and if I had known, the race would have ushered in a new round of technological innovation."

As soon as they stepped into the interior of the area, the collectors drove the eyeballs on the roots and tendrils, looking at the environment inside the area to collect information, but this act of collecting information also directly caused them to be stunned by the technology of the Hui civilization - the space inside the area is larger than the volume of the outer area. 678

The area inside is very large, and the collector simply conducted a radio ranging, and found that the area of the interior space actually reached 25 square kilometers, which corresponds to the 25 square meters outside.

After several attempts, the collectors found that space-time is like a reduction of the same scale, entering from two different positions one meter apart from each other on the outside, and one kilometer apart from each other on the inside, which is accurate to the microscopic molecular level, but whether it is only at the molecular level, the two collectors dare not guarantee, because their detection scale can only reach the microscopic molecular level, and there is no technical means for deeper detection.

"It's the tiredness of time and space, and time and space are involuted."

"That's all it can say."

The two gatherers observed the difference between the inner and outer space for a while before continuing to explore the things inside the area, for them, no matter what existed in the inner area, they would not lose this time, and the extinct Hui civilization used actual creations to make the gatherers understand that the original time and space could still play like this.

Exploring the interior of the area, the gatherer's roots soon discovered something.

It is a lot of instruments, it looks very new, as if it has just come down from the production line, there are many luminous lines on the instrument, it looks very sci-fi, the collector confirmed after studying it, these are lines, these luminous lines are superconductors of circulating current, designed to be so estimated to conform to the aesthetics of Hui people, otherwise plug in a bunch of superconductor wires, the effect is the same.

In the instrument, there are some things that appear to be culture tanks, cylindrical, transparent containers that have not yet been determined, and the inside of the container is filled with transparent liquid, and various strange-shaped creatures float in the liquid.

It's a bit like a dried corpse, skinny, but the gatherers don't dare to guarantee that this is whether these creatures are born like this, so they don't make a direct judgment.

The appearance of the creatures in each trough is different, but none of them belong to the Hui people, and the collectors spread the roots and search around but did not find the species suspected to be the appearance of the Hui people.

Obviously, since it exists in the laboratory of the Hui civilization and is a species that is not the Hui civilization, there must only be one possibility of 'being the experimental subject of the Hui people'.

"Where to start?"

Gatherers who have explored the area are curious about almost everything in the area, and because of this, they don't know where to start first, a bit like Scrooge accidentally discovering treasure and not knowing which treasure to move home first.

The clan first used their thinking tentacles to mark all the instruments in the internal space of the area within the network of life fields, and then marked the very center of the area.

"These are secondary, I'm more interested in the above thing."

The so-called upper is above the roots in the area, and the inner area is very different from the outside world, and the roots of the gatherer are pressed against the inner wall by an invisible force, and this inner wall is the 'earth' below the roots.

In the center, there is a sphere that glows all the time, but it emits microwaves, which are the source of microwaves that have hindered the exploration of the collectors.
