Radix took Qinguan and walked smoothly along the wide street.

On both sides of the street, there are buildings of different styles, all of which are transparent or translucent, and at the same time reflect colored light, which looks transparent and gorgeous.

Along the way, see aliens of different appearances and shapes.

Radix kept greeting them, and gave Qin Guan a brief introduction, this one is from the Big Melon Galaxy, and the other is from the Straw Hat Galaxy.

"I know all the races here, we're all friends.

"Later, you can visit them and become friends with them. When you reach a certain level of opinion, you can accept small tasks in exchange for honor points, or you can get their gifts.

"There are also a few shops in the city, open to you, and you can exchange honor points from their shops for supplies."

Qin Guan nodded, this is a routine with the game on the earth.

After a tour of the city, the open-top hovering low-altitude aircraft flew close to the ground outside the city.

"By the way, how long have you survived on this planet?" Qin Guan asked curiously, "And you are all male, how did you reproduce later?" ”

Edith paused for a few seconds: "According to the timeline logic, I can't answer this question. ”

Qin Guan challenged the NPC's program again: "There must be relevant background information in the knowledge base of the system, right?" Why not talk about it? ”

Radix was helpless for a moment, and began to say in a mechanical tone of memorizing texts:

[Interstellar Encyclopedia, Relics, Rena Star, Exile, Great Wilderness Star Life History]

[The Lena Star Exile found the legendary interstellar exile homeland and survived in the Great Wilderness Star until now.]

There are two ways in which they reproduce.

The first is the nuclear replication technology, which extracts the complete genes in the nucleus and breeds cloned offspring.

This technology can change gender and inherit the memories of previous generations.

The purpose of using this technique is to preserve the entire emotional and intellectual memory of the first generation of exiles.

Second, the artificial meiosis technology of the nucleus splits the gene meiosis in the nucleus into two groups, which are matched with genetic cells to breed new offspring with a sex ratio of 1:1.

The second technique was only used for 30 years, and many offspring were reproduced, and when the racial base reached a certain number, the natural way of reproduction was restored. 】

After listening to this, Qin Guan thought for a moment: "So, in a biological sense, you will die of natural old age; But in another sense, you keep cloning yourself and inheriting the memories of the original you, so you have survived until now, more than 2,000 years after this timeline? ”

Edith: "Yes. Please don't ask any more questions that don't go against the logic of the timeline. ”

Qin Guan ignored Radith's timeline and continued to ask, "If I can find the Great Desolate Star in the real universe, I can still see you?" ”

Edith: "No, we have never crossed paths in the real universe, and I can't know you. ”

"Oh, that's really a problem...... Qin thought to himself, if he really had the opportunity to see Radith in the real universe, he would recognize him at a glance, but he didn't know himself, it would be difficult to communicate.

Do you want to tell that Reddis that I know you in the virtual world?

He put the idea out there.

Edith said expressionlessly, "You're thinking too much, first you have to be strong enough to fly out of your galaxy." Secondly, I am just a data modeler, and I may not be like this in the real universe. ”

Qin Guan: "......"

Look down on people again, the universe is so big, can't I even fly out of the star system of the blue planet?

Someday I'll fly to you!

Also, how careless is this outsourcing modeling?

Now that we all know so much about the history of the exiles, how hard can it be to take a photo and copy a template?

……

Soon, the aircraft carried Qin Guan to the edge of the city.

"In the places where we live, there is an anti-gravity energy field that maintains a comfortable standard value. But outside the city, there is no such energy field......"

As he spoke, the flying machine slammed down to a height of about two fists, and Qin Guan only felt that his body was sinking instantly, as if his weight had increased N times.

"You feel it, it's the effect, the gravitational pull is very strong."

Qin Guan: "It's really big~~"

At this time, the distance between the aircraft and the ground was only more than 20 centimeters, almost rubbing against the ground, and it was slightly bumpy.

Radius opens an interface in front of him to monitor the real-time image of the bottom of the aircraft.

"The ground is not flat, and if you don't pay attention to it, you are likely to bump the chassis~~."

……

As far as Qin Guan could see, the plains near and the irregular diamond mountains in the distance constituted a vast crystal world that was transparent and crystalline.

In some places, you can see hundreds of meters deep underground, all of which are high-purity diamond formations, while the distant mountains show a variety of colors, with very light purple, yellow, and sky blue.

Qin Guan was attracted and shocked by the scenery in front of him.

"This planet is full of diamonds? Nothing else? ”

Edith: "Yes, it's a carbon-based planet. ”

He suddenly began to popularize science, and said in a text-memorizing tone:

"This planet was originally a star, and the star you can see when you look up is a binary star system.

But this star ended its life early and became what it is now.

Every star is destined to die, and when the fuel runs out and the hydrogen runs out, gravity overcomes fusion, at which point the outward expansion generated by fusion weakens, the star collapses inward, and the outer layer heats up and explodes into a red giant.

Later, due to the lack of hydrogen in the star, helium begins to burn, fusing it into carbon.

Red giants slowly turn into white dwarfs, and the heat energy escapes into the universe, leaving only a dense core.

White dwarfs are 1 million times denser than ordinary rocks, and under certain conditions, they can become a diamond planet.

That's what happened to the Great Wilderness Star.

On this planet, there is no water or rock on the surface of the planet, and carbon is in the form of diamonds, as well as graphite, iron, silicon carbide, and silicate, and that's probably the case. ”

Radix finished memorizing the knowledge points dryly, and Qin Guan listened to it and asked curiously: "Then where does the water you need to survive come from?" ”

Edith: "Taken from the depths of the earth, or from space, like capturing a comet, the water element obtained is enough to feed the existing life on this planet for decades.

"In the beginning, because the planet was too inhospitable, there were no naturally grown plants, and there was no naturally living life, so it was called the Great Wilderness Star.

"Later, after a group of settlers, the planet was transformed into a habitable planet, and we used various technological means to create comfortable living conditions, which is what you see now."

"Uh-oh." Qin Guan nodded.

Radius then said: "By the way, there is another very important reason why this great wilderness star can gradually become a famous refuge place in the stars......
