Ice, fire and thunder are intertwined in the sky, and March is dancing in the dream star dome.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

At this time, the nova returned to orbit in space, orbiting the star Lan. In the cockpit, Xiao Cheng resigned himself to quickly entering data on the computer, while recalling Xinglan's words that day......

"Hmph~ It's decided! Xiao Cheng, how about you get an ice moon, a fire moon and a thunder moon? The specific planning tasks are up to you! ”

“…… What? How do you get this strange thing! ”

"Hmm...... Didn't the information collected before say that there was a ...... called "It seems that he searched the memory bank for a while, and then Xinglan smiled and continued, "That thing called the magic element......"

"How can there be such a thing in reality!" Xiao Cheng felt an urge to collapse, "Be sober, hey!" Are you an adolescent secondary 2 girl? ”

"This is to allow future civilizations to cultivate their ability to adapt to different environments before landing on other planets!"

“…… Don't use this seemingly righteous excuse to do things that you do because you think it's fun, hey! I've seen through it completely! And if you play like this, maybe people will give up on the moon at all! ”

"It doesn't matter whatever, it's decided anyway." Xinglan came to a conclusion decisively, "As for how to get it out...... This task is up to you! ”

"Hey ......"

"Oh, and ......" Xinglan rubbed Xiao Cheng's face happily, "The task of naming the satellite is also handed over to you~"

"Huh?"

The memories end.

"What a difficult task...... "The young man smiled confidently as he looked at the analog image displayed on the screen, "but it's not too much for me. ”

So......

"Xiao Cheng Xiao Cheng~" Xiao Guang popped up, "Is it done?" ”

"Hmm...... I'm really anxious......" Xiao Cheng subconsciously looked at the dazzling star in the distance, and secretly wondered how a star with such a strange personality was formed, "According to your requirements, I have designed a rough blueprint. First of all, it's true that Lanxing has a total of three moons. ”

"Uh-huh." Xinglan fluttered up and down vigorously to nod, "If Xiao Cheng feels that it is not enough, even if he moves a few more satellites, it will be no problem at all~"

“…… Not necessarily. Xiao Cheng silently wiped away the cold sweat behind his head and turned on the computer's simulated image, "A moon of fire, a moon of ice and a moon of thunder, so you should be satisfied." ”

"Looks really good." Xinglan exclaimed softly and looked at the three brightly colored satellites on the screen, "But are you sure there is a really feasible transformation plan?" ”

"Of course." Xiao Cheng nodded very affirmatively, "Since the plan has been proposed, of course, it is necessary to ensure the feasibility." In fact, even the names of the three moons of ice, fire, and thunder, I have roughly determined that they are Frost Rain, Gangli, and Qing Xuan......"

"I don't understand it at all, but it feels amazing......

"Well, that's more like a formal name. Although the future civilized race will definitely feel that it is enough to choke ......" Xiao Cheng couldn't help but wipe a handful of bitter tears for them in his heart, "Other planets are too far away, so when they first started to develop aerospace technology, they must have preferred the satellites of their home planet, but ......"

Silently covering his face, Xiao Cheng continued to mourn in his heart for the future civilization: "Thunder Moon, as the name suggests, must need a thick layer of lightning clouds, and it will definitely be kicked out of the preferred target directly." ”

"Fire Moon, just listen to the name, you know how difficult it is to land in this kind of magma boiling and blazing place, and you will choose this when your head is pumped."

"Ice Moon, it seems to be the best ...... to land" Xiao Cheng showed an expression of "If you don't die, you won't die, why don't you understand", "If they choose the ice to land, but the ice melts due to the air flow from the braking rocket and the impact of the spaceship...... Slipping or something, falling into a puddle or something...... I'll go! I can't imagine the faint sadness of an aerospace engineer......"

“…… It seems to be very pitiful......" Xinglan said hesitantly, "Or, forget it?" ”

"It's okay! Never mind! Xiao Cheng laughed, "Xinglan, you have to have confidence in the race you have created~ With infinite creativity, they will be able to overcome all these problems after all!" ”

"Oh......"

In fact, Xiao Cheng's heart is ...... How could the blueprints I had spent so much time come up with in vain! I can't be the only one who is tormented by Xiao Xinglan's whimsy! The intelligent race of the future~ Don't blame me for being ruthless! If you want to blame, blame you for being an innocent and deceitful creator~ Oh hahaha!

This young man, you hacked ......

……

"Ahem, anyway......" Xiao Cheng's eyes showed a strong confidence, "Let me introduce you to the blueprint for the satellite transformation that I just finished~"

"Well, we're listening."

"First of all, considering that we need to use scientific means to achieve these magical and wonderful scenery......" Xiao Cheng clicked on the screen, and the snow-white satellite in the screen quickly zoomed in, "I recommend the satellite closest to Lanxing and the lowest orbital altitude, choose the Ice Moon, which is also the simplest design blueprint." ”

"Frost Moon?" Xinglan muttered, "A nice name." ”

"Yes, Frost Rain." Xiao Cheng clicked on the snow-white satellite, and dense data jumped out on the side, "It can be said that Shuanglin is the best one of the three satellites." To put it bluntly, the Ice Moon is an ice and snow world, which is one of the reasons why I chose it in the lowest orbit, for the future development of space technology, low-orbit satellites and the Ice Moon are the best choice for landing. Xinglan? ”

"Huh?"

"Is there any ice comet left over from the last ocean-making session?"

"Yes." Xinglan nodded and said, "Just in case, I deliberately pulled some more ice comets into the inner orbit. ”

"Pull them over," Xiao Cheng marked dozens ......of points on Shuanglin's simulation renderings, "Putting ice comets at these locations can make most of Shuanglin's surface covered with thick ice with maximum efficiency, so that it is a veritable Ice Moon." However, there are still some problems......"

"Huh?"

"The biggest problem is the ...... atmosphere," Xiao Cheng said solemnly, "Our spoof has added a lot of obstacles to future moon landings, so my suggestion is to send a group of planet makers to blow away the water vapor sublimated by the collision between the ice comet and the frost show, so that the frost rain cannot form an atmosphere." The presence or absence of an atmosphere has a great impact on whether the lunar module can take off again after landing, and the friction of the atmosphere will make it difficult for the early lunar module to return to space, and once there is an atmosphere, there will be complex meteorological changes, and various climates are also easy to cause damage to the lunar rover. ”

"It's so bad to have an atmosphere......"

"However, there are also troubles in maintaining a vacuum environment...... Xiao Cheng rubbed his forehead again, and said with a deep headache, "A large area of ice cover, and no atmospheric scattering, will make Shuanglin a huge reflector." It's not just a matter of the moon shining brightly at night, it may even lead to higher temperatures in parts of the planet...... However, all things considered, I still recommend not installing an atmosphere, not to mention that the size of the frost is too small, and it is difficult to retain the atmosphere. ”

"Well, that's a sign of complete trust in you." Xinglan grinned, "I can't see that your guy's analytical skills are not bad." ”

…… Although the star does not have the attribute of gender, it always feels that Xinglan is the appearance of a little girl. Xiao Cheng silently spit out, and then said solemnly: "Next, it's the Moon of Fire, Gang Li." ”

"This is the satellite in the middle, right?" Looking at the rendering of the Fire Moon, Xinglan said with certainty.

"That's right, it's the satellite in the middle orbit." Xiao Cheng smiled, "The Moon of Fire naturally has to have flames. While it's unlikely to make a super fireball like a star, it's much easier to just fill it with magma and hot gas. In this case, the big question is: how to keep the heat! ”

Xinglan flashed suspiciously: "Why keep the heat?" ”

"It's simple, because of entropy." Xiao Cheng said, "You also know that according to the second law of thermodynamics, heat will always automatically transfer from a hot object to a low temperature object, which is a basic physical law that none of us are capable of changing. In the universe, heat from the planet's interior is constantly dissipated into space. If the planet is very small, it will cool down soon, not to mention that Gangli is only a satellite, unlike Lanxing, even if this satellite heats the core, it is difficult to maintain geothermal energy, at least it will definitely not be able to maintain the appearance of intelligent beings in Lanxing. ”

"What about gravity?" Xinglan, who searched through the memory bank, suggested, "Isn't it true that some moons orbit around the planet with a high eccentricity, and then the distance is close, and they are stretched and squeezed by gravity at different positions, thus gaining a steady stream of internal heat? Such energy is hardly exhausted......"

"No way!" Xiao Cheng shook his head, "Please see it clearly...... That happens on the moons of gas giants, and ordinary solid planets simply don't have such a strong gravitational pull to heat the inner cores of the moons. ”

"Hey...... So what to do? ”

Xiao Cheng shrugged: "You can only use stupid methods!" Put a large amount of radioactive elements into the interior of the planet...... It must not be the kind where a nuclear explosion happens! They use their slow decay to heat the planet's core, and to retain heat, they need an atmosphere, preferably one dominated by greenhouse gases such as carbon dioxide, sulphur dioxide, and methane. However, if you do this, it will be very difficult to go to the moon in the future...... Slowly descend on the shores of a lava lake under the erosion of acid rain...... I can already imagine the faces of the engineers who will land on the moon in the future......"

"Hmm, why do you always feel sorry for the future civilized race......"

"Forehead......," Xiao Cheng hurriedly comforted, "Think about it, in this case, there must be frequent geological activities in Gangli, and there will be many volcanoes, right?" ”

"Hmm." Xinglan flashed in confusion.

"Then you can watch the fireworks directly on Lanxing~" Xiao Cheng continued to say in a seductive tone, "Because the gravitational force is not large, if you are willing, you can also put a super fireworks that can rush out of the atmosphere!" The life on the planet will definitely take this as a beautiful spectacle! ”

"Hey...... That's right! Xing Lan thought for a while, but still agreed with Xiao Cheng's opinion, "Compared to the beautiful spectacle, I believe that this problem can still be overcome!" ”

Xiao Cheng: "......"

Damn, what's going on with this deep sense of guilt? If you continue like this, you're going to start self-loathing!

"Ahem...... Xiao Cheng coughed to stabilize his mood, and then said, "In order to generate more heat, Xinglan, you can also throw a meteorite on top of Gangli from time to time. It's not an ice comet, it's a meteorite made of stone or metal. A meteorite can bring a lot of heat and can maintain the planet's thermal environment very well. ”

"Well, good idea......"

Seeing that Xing Lan had passed those malicious transformation suggestions so easily, Xiao Cheng couldn't help but imagine those intelligent beings in the future watching the huge points of light magnify in the sky, fleeing in all directions in horror, only to see the points of light slamming into the fiery red moon......

Well, there may be a lot of new myths and legends born as a result.

For example, Chang'e hit the moon or something, Tiangu ran to the moon or something, and then shot the moon or something......

Just a few sentences read together...... Something seems wrong? Inexplicably discordant......

Hawkers, forget it, you don't have to worry about the details~

……

To the original sunny youth, you have completely fallen into the abyss of blackness......

"Then, it's the last one~" Xiao Cheng lightly tapped the screen, a trace of electricity flashing on the screen, "The outermost, the most complicated, will also be the most useful...... Moon of Thunder, Death! ”
