Although she was very curious about how Ruby drank the poisonous dragon's saliva, Moyuna only asked once, and received a perfunctory answer like 'an accident'.

The incident of the attack on the mayor did not have the slightest impact on the lives of the two people, and the jade piece called the key Lubi did not study the reason, of course, there are more such things as the other world, so this jade piece that people dream of was thrown into the corner to eat ashes.

'Zizizi'

The lamp above Moyuna's head suddenly made a noisy sound, making the Dharma God put down the scroll in his hand and raised his head in confusion, not only the lamp, but also some other electrical appliances in the house.

"Ruby, what's going on?"

For this kind of thing that glows all the time, Mo Yuna has long been used to it, and it can be described in four words that are very magical, the magic crystal used as a light source in ordinary families has to replenish the magic power every day, how can there be this kind of thing that can be lit by pressing the switch, and before today, Mo Yuna has always thought that this thing called the lamp tube is perpetual.

"It's running out of power."

"Electricity?"

The Fashen girl tilted her head, and a crackling electric light condensed on her fingers and handed it to Ruby.

"Go, stay away from me."

Ruby waved his hand to drive away the funny Moyuna, and the ghost knew how the magicians of this world managed to hold electricity in their hands, anyway, Ruby was self-aware, if he touched the electricity with his bare hands, he would definitely be electrocuted into an explosive head, and Moyuna also dissipated the magic with her own boredom and followed Luby out of the house.

The two of them came to the back of the hill, which was in the opposite direction from their residence, and it was the first time that Moyuna had come here, and it was the first time she had seen the strange prop, two pillars about three or four meters high were inserted into the ground, and three irregularly shaped blades were inlaid at the top of which were slowly turning.

"Does this thing have anything to do with electricity?"

"Well, it's a wind turbine, it's a little rusty."

Lu Bi checked his windmill and found that there were obvious rusts on it, and the kinetic energy generated by the windmill if it couldn't turn was much less, and the power generation was naturally inadequate.

This can't be helped, the materials used in Ruby's manufacturing were inferior at the beginning, but even these inferior materials were made up for a long time, and Rubi was also desperate, if the conditions allowed him, he would definitely use Gundam Nimes alloy to make it.

"Wind? Is there a relationship between wind and electricity? Is that the wind magic the restraint of the electric magic, right? ”

"No, the principle of wind power generation is to use the wind to drive the windmill blades to rotate, and then increase the speed of rotation through the speed increaser to promote the generator to generate electricity, convert the kinetic energy of the wind into mechanical kinetic energy, and then convert the mechanical energy into electric kinetic energy."

"Anyway, all in all, it's the wind, right, the wind magic [Vacuum Whirlwind Break]"

Moyuna's eyes began to roll when she listened to Luby's explanation, she didn't know what Luby was going to say at all, she only understood that there was wind and electricity, it was very simple, and when she raised her hand, a seventh-level magic was thrown over.

Ruby didn't even have time to stop it, so he watched his windmill turn into pieces of iron under the raging wind, and there was no need to repair it, so he went back to the furnace and rebuilt it.

"Moyuna!"

"What, what?"

Hearing Ruby suddenly call her name, Moyuna came back to her senses, looking at the angry expression on his face and feeling a little overwhelmed.

"Can you think a little bit before you do something? Can this thing withstand that much magic? ”

"You, you murder me! You're killing me for this pile of broken copper and iron, right? ”

Moyuna finally reacted that Lubi was angry, a feeling of grievance arose, two months, they lived together for two months, Lubi didn't kill her once, Moyuna didn't know the value of these things, but Lubi regarded them as more important than himself!

"I'm reasoning with you, why can't you think about magic first and foremost in whatever you do, and can't you think a little about my science?"

"Because I'm a magician! Isn't that science-breaking of yours as good as my magic? ”

"Since you said so, let's compare, let me tell you clearly, what science can do, you magic will never be able to do."

Ruby can be said to be very annoyed, Moyuna not only did something wrong and did not admit his mistake, but also insulted his favorite science, what if his faith was insulted? Answer: The only way to fight to the death is to fight.

"Okay, that's better than heaven."

Moyuna almost gritted her teeth and agreed to Ruby, and directly threw out one of the most demanding conditions, flying has always been the dream of human beings, and the desire for the sky of flightless creatures has never been alleviated, even in the world of magic, if you want to fly by your own strength, you must at least reach the level of a magister, because only a magus can use the seventh-level wind magic [Wings of Freedom] to fly into the sky.

That's right, the Fashen girl has a clear bully on her face, why do you fly up when you don't even have magic power.

"Hmph, naïve, humanity conquered the skies back in the early twentieth century, Dragon, spit out my hot air balloon gear."

"Tsk, you're more boring than I thought."

Dragon had been watching from Ruby's head, both of them were the top beings in their respective fields, but they quarreled like children like this and proposed a duel, and Dragon, who disdained to be with them, released a large piece of cloth and a large basket from the space inside him and then fell silent.

"Look, stupid magician."

Lubi linked the hot air balloon to the gondola, and then used a blower to blow the balloon into it, and waited until it was fully unfolded before putting in the most important fuel, propane, how difficult it was to make this fuel in a ghost place like another world You can imagine, Lubi finally saved a little bit and put it all in, in order not to embarrass the earthlings.

"What's the matter, keep up."

He said to Moyuna when Ruby was already more than ten meters above the ground, his face full of indifference.

“... I don't believe you can fly higher than me. ”

Seeing that Ruby really went to the sky, Mo Yuna was a little unacceptable, it seemed that Ruby could break her cognition at any time, here of course she couldn't admit defeat, and immediately waved her invisible wings to follow.

One kilometer

Two kilometers

5 thousand meters

As the hot air balloon rises, the struggle between the two continues, Moyuna has always maintained the same altitude as Ruby, she hasn't been on such a high sky since she learned to fly, and today she is also out of the way, and she gets angry when she sees Ruby's nasty face, she carefully controls the flight altitude and balance here, but Ruby is leisurely drinking coffee there, and from time to time she looks at the scenery in the same place, which is really unfair.

"How's it going, have you thrown in the towel?"

It wasn't until he rose to about 10,000 meters that Lubi spoke, he was covered with a blanket to keep out the cold, this high level of oxygen had obviously decreased, and Moyuna was not comfortable, she didn't have any equipment to protect against the cold, and there was a small layer of frost on her eyebrows.

"I won't admit defeat!"

"Then I'll throw in the towel."

Moyuna's stubbornness was expected, and Rubi also sighed and handed his hand to Moyuna.

"Huh?"

Moyuna looked at the hand in a daze, forgetting to maintain the height for a while and fell a lot, but she quickly caught up and looked at Ruby suspiciously, not knowing what conspiracy he was doing.

"I just want to tell you not to underestimate science, as education is enough."

Ruby grabbed Moyuna by the arm and pulled her into the basket, removed the blanket from her body and put it behind her back, and handed her a hot drink.

"Don't you want me to break your stuff?"

"You can do it again when you run out of things, and getting hurt for this kind of thing is more than worth the loss."

Ruby is right, although the hot air balloon still has room to rise, but further up it is not a place where the flesh can reach, I don't know what will happen to Moyuna, he will definitely be injured.

"Well, it's better to play with Akua like a fool than to fight with you."

The pleasure in her heart made Moyuna have to try to control her face from laughing, she seems to have misunderstood what Ruby meant, feeling that Ruby was afraid that she would be hurt before giving in, in fact, Lubi herself is much more dangerous than her.

"Moyuna, let's try this."

After returning home, Lubi made a simple electricity tester non-stop to test whether the electricity emitted by Moyuna could be used, and the answer was of course yes.

"Sure enough, you're very useful, and the power supply will be handed over to you in the future!"

After that, as the person in charge of the water source, Moyuna became the power source again.
