In the cosmology, there are some high-end knowledge concepts.

It's just a concept, and this is what the Dragon King came up with.

For example, the self-universe, such as the dimensional universe, such as the parallel universe.

Students of all cosmological disciplines are aware of these concepts.

The self-universe refers to the cosmic space in which it is located, while the dimensional universe is other universes, including low-dimensional and high-dimensional universes, which are commonly known as dimensional universes, such as the two-dimensional universe and the three-dimensional universe, and the parallel universe is the cosmic space parallel to the self-universe.

Spatial transitions generally refer to the way in which they move in the universe of the ego, which is somewhat similar to teleportation.

For example, from Luoyang to Qingping County, the general way of moving is to fly from Luoyang to Qingping County or to Qingping County, while the spatial transition is similar to putting two places on a map, then folding them so that two points are connected, and then breaking the space from one point and coming directly to another point.

This kind of movement can now be done by the Tree of Knowledge, but the distance is not too far, yes, even a billion kilometers is not far away compared to the vast universe, because in general, such a way of moving can often move a distance of hundreds or thousands of light years, and even cross distant galaxies at once.

This kind of space can be regarded as a real spatial jump, and the dragon king can only make a small fuss.

As for the dimensional universes and parallel universes in the back, the way of movement will be even more exaggerated, so Huang Xu will only think at first that the spaceship has only made a space jump, and it has not arrived in other universes, which is a relatively normal judgment.

But even a simple spatial jump gave Huang Xu a big headache, because he lost his sense of direction.

He didn't know how far this space jump was, and he didn't know where it was going, the universe was so vast that it was really very difficult to get back on track after losing its direction.

Even if you are unlucky, this space jump and fly directly out of the galaxy, it will be really a big trouble, because with the ability of Explorer 4, even if you know the right path, it will take a long time to return to the galaxy and return to the solar system, at least, with their lifespan, they can't do this.

Fortunately, this is just Huang Xu's speculation, and Huang Xu doesn't think they will be unlucky like this.

So, the most important thing at the moment is to figure out this place first, then try to figure out the star field where this planet is located, and finally, find out how far away this is from the solar system...

First let the spacecraft start to self-test and detect the surrounding environment, Huang Xu clapped his hands at everyone: "Everyone, we may be in trouble again." ”

Well, Huang Xu's line has been said several times, anyway, the crew is almost immune, trouble? How often did they not run into trouble? Explorer 4 seems to have been born out of trouble.

Fortunately, the crew saw the scene outside the cabin.

"Isn't this underwater?"

"Doesn't seem like a problem? Instead, it won the lottery. ”

"Since there is water, there is a possibility that there are living things, so how can it be called trouble?"

"Were we still in the stars just now? Why did you suddenly run into the water? That maelstrom leads into the water? On a planet? ”

After the crew discussed for a while, Huang Xu said: "We should have gone through a space jump just now and came to a star field, and the trouble I am talking about is that we are really lost and don't know the location." ”

This is really not good news, and being disoriented means that they will most likely not find their way back to their ancestral planet, and they will most likely drift through the universe until death comes.

But the crew was only frustrated for a moment, and then they cheered up, at least, they were okay now, weren't they? After so much experience, the crew on Explorer IV is already all big hearted and disoriented? Then find the way home, don't you?

Soon, the general direction was decided, and the first thing was to figure out what kind of place this was.

At this time, the data analysis of the intelligent system on the spacecraft also came, and after reading the data, everyone found that the water outside should be seawater, because it contains salt, but at the same time, the seawater contains the special energy of the big whirlpool that tore them into, but the special energy of the big whirlpool is very pure, and here, it is mixed with seawater.

I don't know if it's because of this special energy, the pressure of the sea water outside is 1.25 times higher than the sea water on the ancestral star, but other than that, the sea water here is not much different from the sea water on the ancestral star.

Through these data, everyone can already clearly know that this is likely to be another planet similar to the ancestral star.

The frustration and unhappiness of the crew was quickly diluted by this news, this is a planet similar to the ancestral star, it is rare, and it is not unusual if there are intelligent beings, and it also means that they can survive even if they can't find their way home.

Under the control of the crew, the ship began to roar, and everyone was ready to leave this place, the bottom of the water is not a place for everyone to stay, the land is.

"Look, what's that?" One of the crew members screamed.

When the spaceship is not started, there will not be a trace of light on the periphery of the spaceship, but as soon as it starts, the searchlight equipment in front of the spaceship will light up, and in the dark place, such light is too attractive to other creatures, after all, many creatures have phototaxis properties.

A massive creature burst into the crew's sight.

This creature looks like a huge shark, but it is obviously much larger than the shark on the ancestral star, the shark of the ancestral star is generally only five or six meters long, and the great white shark is only a dozen meters, and this shark looks like it must be fifty or sixty meters long.

Although the crew often faced the dragon king, the real size of the dragon king was far larger than this shark, but the dragon king was generally reduced in size, and almost all of what everyone saw was the size of the dragon king twenty meters, so this fifty or sixty meters long shark really shocked everyone.

"What a big guy."

"It feels like it's fierce."

"Since there are such large sharks, there is no doubt that there must be living beings on this planet, and the biological chain is very developed."

"Yes, that's good news."

Although the shark is large, the spaceship is larger, even if it is only a backup spaceship, the shark does not have a head iron attack spaceship, and after swimming around the edge of the spaceship, it swims away slowly.

The crowd didn't pay attention to the shark, but controlled the spacecraft to continue upward, preparing to leave the water first.

I don't know what's going on, anyway, the place where they landed is not very deep, maybe about a thousand meters? Soon, the spaceship floated to the surface.

During this period, everyone saw several large sharks and some other fish one after another, which fully confirmed that the biological chain here is very developed.
