Meng Ke sat up suddenly, but he was already shocked into a cold sweat.

"What a weird dream ......"

Wiping the sweat from his forehead, Meng Ke turned his head to look at the clock on the bedside table, it was half past two in the morning.

It was still early in the morning, but Meng Ke was no longer sleepy, so he simply got up and went to the balcony, and leaned on a recliner tiredly in the evening breeze.

I don't know why, every time he wakes up in the past few days, he feels inexplicably tired, as if he has just finished a marathon, and his bones are numb and full of tiredness.

The same is true today, Meng Ke leaned back in the chair, turned on the massage switch, and quietly looked up at the night.

The sky tonight was very clear, without a trace of dark clouds, it was really bright stars and moons, and he didn't know how long it had been since he had seen the starry sky like this.

It's just that now he looks preoccupied, and he looks so distracted and absent-minded even when he glances at the starry sky.

After being stunned for a while, Meng Ke suddenly asked, "Zhi Brain, can you tell me about things in the universe?" ”

"Which one do you want to hear?" The figure of Zhi Brain appeared with the floating screen, and he didn't ask Meng Ke what kind of wind he smoked in the middle of the night, but asked softly.

Meng Ke thought for a moment and said, "Can you tell me about the civilized races near the solar system?" Let's choose one that is less than 10 light years. ”

"Yes." Zhi Brain did not refuse, nodded slightly, then organized the language, and said: "To talk about this problem, you must first understand one thing, that is, the Milky Way has four spiral arms, namely the 3,000 parsec arm, the centaur arm, the Orion arm, and the Perseus arm, and the solar system is within the Orion arm.

To be precise, the solar system is at the edge of the Orion Spiral Arm, halfway between the Centaur Spiral Arm and the Perseus Spiral Arm, closest to the Perseus Spiral Arm. There are seven star systems within 10 light-years of it, from near to far: α Centauri, Barnard, Woolf 359, Brande 2147, UV Cetus, Sirius, and Ross 154.

Among them, there are only two star systems where there are civilized races, one is α Centauri, and the other is Sirius, which one do you want to hear first? ”

"Hmm......" Meng Ke was silent for a moment and asked, "Is the Centauri α a three-body world?" ”

"Like science fiction? Pretty much that. Zhi Brain nodded and explained: "Your earth civilization understands well, the α Centauri is indeed a triple galaxy, it is composed of three stars, about 4.3 light-years away from the solar system, and the αC star, which is what you often call Proxima Centauri, is 4.2 light-years away from the solar system.

As the author of the novel depicts in science fiction, the Centauri α does have a 'three-body' life. They belong to the alien race that lives in the stars, so for the sake of your understanding, let's call them the 'Trisolar' for the time being.

The Trisolaran is a kind of soft-bodied creature, the shape is very similar to the slime, the technology system is similar to the earth's technological civilization, the civilization level is the middle level of the second level, the number of races is about 17 billion, mainly living on the αB star, only less than 100 million people are scattered on the other two stars......"

"Uh, wait a minute." Meng Ke suddenly stopped Zhi Brain and asked puzzledly, "What is an alien race?" ”

"Okay, I think I'd better tell you about the division of intelligent life first." Zhi Brain held his forehead with his hand and said helplessly: "Generally speaking, intelligent life is divided into four forms, namely human civilization, human-like civilization, intelligent beast race and alien race.

I won't tell you about the first three, but you can guess it, so I'll tell you about the alien race alone.

The so-called alien race is the existence of a life form that violates normal life forms, such as planetary extreme evolution civilizations, energy-type extreme evolution civilizations, information limit evolution civilizations, parasitic civilizations, and mollusc races, all of which belong to this category. ”

As he spoke, Zhi Brain pulled out a floating screen and showed Meng Ke several alien forms.

After Meng Ke finished reading it, he suddenly nodded in understanding, it turns out that the alien race is an alien!

Then I listened to Zhi Brain continue to explain: "In addition, there is a way to distinguish different races, that is, the place of residence. Generally speaking, normal intelligent life lives on living planets, which are the planets that your earth civilization often refers to, and only aliens live in stars, white dwarfs, neutron stars, and even black holes. ”

After finishing speaking, Zhi Brain asked, "Do you understand?" ”

"Got it!" Meng Ke nodded heavily, and then said, "You can continue to talk about the civilized race of Sirius. ”

"Well, Sirius has some similarities with α Centauri, because it is a binary star system......" Then, Zhi Brain explained Sirius's binary star system and the intelligent life that existed in it.

Meng Ke sat on the recliner and listened quietly, asking some questions from time to time, and Zhi Brain would tell him a lot of nouns and terms around his questions that he could and couldn't understand, and before he knew it, it was dawn

“…… Okay, that's all for now, it's time for breakfast. After a pause, he ended his explanation of VY Canis Major (the largest known star, the Earth is only the size of a grain of sand compared to it).

Meng Ke also stood up and stretched, only to feel that the bones all over his body were stretched out at this moment, making a crisp sound of "crackling", which was almost as if he was about to fall apart, which was extremely terrifying.

After collecting his thoughts, Meng Ke took the wet towel handed over by the mechanical arm and walked towards the restaurant.

Until breakfast, the content of Zhinao's explanation kept coming to his mind.

Although it was only a few hours, it also allowed him to learn about more than a dozen civilized races and as many as forty star systems and some strange stars, which undoubtedly increased his yearning for the universe.

So after breakfast, Meng Ke called Zhi Brain out again.

"How fast is the planet fortress at the pinnacle of a third-level civilization?" That's his new problem.

Zhi Brain was stunned by his question, although he wondered why Meng Ke asked this, but he still answered: "The planet fortresses and warships of the third-level peak civilization can already fly at curvature, so its speed can theoretically reach one hundred and twenty times the speed of light...... But I think you'll have to wear trait creature armor to withstand this speed. ”

As soon as the words fell, Meng Ke had already exclaimed: ", one hundred and twenty times the speed of light? Wouldn't that be enough to cover a journey of 120 light years in a year? ”

"Well, that's fine."

Meng Ke was suddenly excited: "That's it!" I think it's three million points, right? Hurry up and give me a huàn! ”

"Uh......" Zhi Brain was stunned again, but this time it didn't immediately agree, but shook its head and said, "No, I don't have a physical object here." ”

"No physical objects? Then you can make one now! When Meng Ke heard this, he immediately urged.

However, Zhi Brain directly gave him a roll of the eyes, and said angrily: "You think this is a cabbage?" First of all, you'll have to find me a moon moon! ”

Meng Ke: "......"
