"The real world of the Ninth War Zone, their planet is similar to the Earth, I have a general understanding before, their planet is called Lezhang, it sounds like a beautiful name, but the living environment is much worse than the Earth. Their star is actually a red dwarf, and the Movement Star is right in its narrow habitable zone. ”

Ye Qingmian interrupted Su Mancheng, "What is a red dwarf?"

Su Mancheng glanced at Ye Qingmian with idiotic eyes, "What did you learn in school?"

"I studied liberal arts in high school and college, why do you want to know such a thing?" Ye Qingmian said confidently.

"Well, let's just think it's a star that's not too hot and not too big. ”

"Do you really want me to understand that?"

"Then I can only explain it in words you don't understand. ”

"So be it. Ye Qingmian motioned for Su Mancheng to continue.

"The mass of the red dwarf star is relatively small, the surface temperature is only more than 4,000 degrees, and the wavelength of radiation is relatively long, so even during the day, it is red, and the whole world is reddish, and the brightness is about the same as the twilight of the earth, so if you want to go over, you don't need to bring sunglasses, but you can still bring some sunscreen because the ultraviolet intensity is relatively high there." ”

"One of the favorable conditions for the formation of planetary life is that it has a long lifespan and can give life enough time to evolve, but also because of the low thermal radiation and low illumination, the habitable zone of the red dwarf is much closer than that of the sun. And the movement star is too close to the red dwarf, so it is tidally locked. ”

Ye Qingmian raised his hand like a schoolboy, "What is Tide Lock?"

"One celestial body rotates around another celestial body at the same time, and the orbital period is the same as the autobiographical period, and the direction is basically the same. ”

"Damn, are you bullying me for not reading much?!, can you say a human word?!" Ye Qingmian said hideously, he really felt that he was silently despised by Su Mancheng.

Su Mancheng rolled his eyes and said, "The tidal locking celestial body rotates for the same time as one revolution, which causes one hemisphere of the movement star to be fixed towards its dwarf, one hemisphere of eternal day, and one hemisphere of eternal night. Like the Sun and Mercury... Oh, I guess you don't know Mercury, so you can understand that the earth is like the moon, and the moon is tidally locked by the earth, so there is always only one hemisphere fixed to the earth. ”

"Oh... So that's why it's always half daytime and half black?"

"Uh-huh, that's it. Su Mancheng nodded impatiently. According to them, the hemisphere facing the red dwarf star is called the day hemisphere, where the average temperature is around 30 to 40 degrees, which is quite harsh for humans. The night hemisphere would have been difficult to live in due to the extremely cold climate, but the atmospheric circulation of the star is relatively strong, which can divert the excess heat in the day hemisphere and avoid freezing in the night hemisphere. ”

"What's the matter with the weird magnetic field that separates the day and night hemispheres?" Ye Qingmian continued to ask.

"While the strong ultraviolet radiation and high-energy charged particles of red dwarfs blow away the planet's atmosphere, the civilization of the Movement Star is all thanks to the strong magnetic field on the dividing line between day and night. It protects the Movement Star from disasters, just like the Earth's magnetic field, except that it is stronger and more protective. The long-term interaction between the particle flow of the red dwarf star and the magnetic field of the movement star has formed the complex magnetic field structure on the morning and dusk line. ”

"The magnetic field on the morning and dusk line of the movement protects the day and night hemispheres, but there is little protection from its own location, where high-intensity radiation can cause damage and mutation of human cell DNA, and brain tissue will age and even die at a faster rate. So it's very difficult for humans to get through that line between day and night. ”

"The ionospheric structure above the Starlight Line is in a state of destruction for most of the time, and regular ionospheric storms have blocked almost all ionosphere-dependent shortwave communication and positioning navigation. Coupled with the chaotic magnetic field conditions and the irregular hurricanes caused by geographical factors, it is not difficult to understand that vehicles are difficult to cross. ”

Ye Qingmian nodded, he probably understood, "Then what's the matter with their biennial flame and cold plague? What is the name of the comet called the Death Star? With their level of technology and your knowledge, is it possible to stop this disaster from the root?"

"Huh. Su Mancheng sneered, "The technological level of the movement star is a hundred years higher than that of the earth, and it can stop a fart." ”

"Tell me?"

"The Death Star is a complete coincidence, the red dwarf of the Movement Star family has basically passed the violent period of its youth and has begun to gradually enter stability, but the red dwarf star will have a periodic violent flare wave every two hundred years or so, and frequent high bursts in a short period of time. ”

"During that time, the light of the red dwarf star will gradually change from red to blue, and the intensity of ultraviolet radiation will surge to more than 10,000 times, which will kill all life that leaks out, and at that time, the strong solar wind caused the temperature of the day hemisphere of the music star to soar, so the only chance to survive is only in the morning and dusk line and the night hemisphere, but in view of the special environment of the dividing line there, it must also be eliminated, so the night hemisphere is left. This is what they call the Plague of Fire. ”

"If the heat disaster is a disaster with the intensity of the red dwarf's activity at the crest of the wave, then the cold disaster is the disaster of the trough, and the solar wind and flare activity of the red dwarf star weakens in the middle of the two heat disasters, and the solar radiation weakens and becomes uniform, so this leads to a decrease in the intensity of the atmospheric circulation of the Movement Star, and the heat of the day hemisphere cannot be dispersed to the night hemisphere through the atmospheric circulation as usual, so the temperature of the night hemisphere will quickly decrease at that time point to form a cold disaster. As for the so-called Death Star, it's just that it happened to coincide with these two points in time in time, so it carried this pot. ”

"The scientists on the movement star probably understand this truth, maybe the eldest grandson Lian'er doesn't understand, or they specially said it in order to give you an intuitive description of this illiterate. Then you should understand by now that the heat and cold disasters there are all caused by the red dwarf star that they live on, so do you still think this problem can be solved at the root?"

Ye Qingmian let out a long sigh in his nose, although he didn't understand it very well, he probably understood that it seemed impossible to completely solve this problem.

"But it's not impossible. Su Mancheng said indifferently.

"What's the solution?"

"Wait, wait for hundreds of millions of years, and when the magnetic field activity of that red dwarf star weakens and completely stabilizes, it's completely OK. ”

", my fossils are gone for hundreds of millions of years. ”

"Huh?" Su Mancheng said in surprise, "Didn't you use this description that the bones and scum are rotten in your hometown?"

Ye Qingmian raised his forehead, "Can you study something serious, who did you learn from this?"

"Yazaki Sanchu, his hometown in the north, he says this at every turn. ”

"Okay, okay, what about the flame crystals that grew out of the fire tree after the fire disaster?" Ye Qingmian felt that this was particularly mysterious, he couldn't understand that a crystal that fell from a number could become an important energy source to support the development of a civilization.

"That's interesting. Su Mancheng seemed to be a little interested, "I've really studied, the movement star is actually really special, the natural production conditions of this kind of flame crystal are too harsh, but it really meets those conditions." ”

"How does that work? How does that tree grow in a high temperature and radiation environment?"

"Don't be funny, all the plants on the surface of the ground are dying in that environment, and the fire tree is just a fiery red color like a tree's lens, and when the flare tide erupts, it is drilled out of the ground little by little by the action of the magnetic field. Su Mancheng unceremoniously laughed at Ye Qingmian's innocence, "In fact, the so-called flame crystal is the broken fragment of the fire tree, which is a special crystal with strong magnetism. ”

"Every time the Movement Star Flame erupts, it's actually the time when the solar wind and flares of the red dwarf star are violently active, as I told you earlier. When a flare erupts, it produces antimatter, which descends on the star with a burst of energy wrapped in a complex magnetic field. ”

"The melting point of the fire tree is very low, and when the activity of the red dwarf star becomes more intense, the surface temperature of the movement star increases, and the fire tree melts and becomes a liquid magnetic material. As the surface temperature of the star drops, the liquid magnetism solidifies into a hollow block, and the antimatter produced by the red dwarf flare is confined to this container, which is the flame crystal. ”

"The flame crystal is not a permanent magnet, as its magnetic properties weaken very slowly, the antimatter restraint ability decreases, and there will be continuous antimatter escaping from the physical void of this flame crystal, colliding with the positive matter in the outside world and exploding and generating a large amount of energy. ”

"Through constant exploration, the Movement Star has gradually mastered the means of capturing these antimatter escaping from the flame crystal, and controlling its gentle release and energy after the collision of positive matter. Honestly, it's cleaner than Earth's nuclear power, but it's dangerous. ”

"The formation of this special flame crystal is too difficult, even if I use the divine power of the circulating world to make it, it will take a lot of effort, so I have to admire the magic of nature. ”

After listening to this, Ye Qingmian felt that his forehead was sweating, and this kind of Yan Jing was a big bomb, "This Yan Jing... In case something goes wrong if the magnetic field is unstable..."

"Bang!" Su Mancheng made an exaggerated gesture, "That's the scene of thousands of nuclear bombs exploding." ”

The corners of Ye Qingmian's mouth twitched, he originally planned to find one or two Yan Crystals to play with, but he didn't expect that he was almost going to die.

"Yan Jing's special strong magnetic field is very destructive to the human body, not only can it not be directly contacted, but even if it is just close, it will be affected, so you must not be idle and have nothing to do with it. Su Mancheng kindly advised.

"Of course I know about this kind of thing! Do you think I'll think it's a walnut? I'll make a!" Ye Qingmian blushed, because he had really had this idea for a moment, and now, he felt that even if he was completely crazy, he would not put the Yan Jing that constrained the antimatter in his hand.

"Huh. ”

"In that case, once the red dwarf star is completely stabilized, there will be no more violent flare waves, and the energy source of the flame crystal on the movement star will no longer appear?"

"yes, that's why they're miserable. ”

"What about Snow Crystal?"

"Snow crystals are fire crystals, but they are blown into the ocean by strong winds, and they are alluvial to the shallows of the night hemisphere after about a hundred years with the movement of ocean currents, so the places where snow crystals are found are generally rivers or beaches. Because it coincided with the so-called cold disaster, ordinary people there would think that the cold disaster brought snow crystals. ”

"That's it..."Ye Qingmian touched his chin, "But I heard that Yanjing is red and Xuejing is blue?"

"Stupid, that kind of magnetic crystal is translucent, of course it looks like red in the red visible light in the day hemisphere, and in the night hemisphere, there is only light blue fluorescent sand, so it looks blue. If you take a little green light and shine it, it's still green. ”

"Whew. Ye Qingmian exhaled a long breath and looked at Su Mancheng seriously, "Has anyone told you that you sometimes show a look that looks at others as fools, special! don't! annoying!"

"Huh, huh?"
