Jack's logic is simple. Pen, fun, pavilion www. biquge。 info

Since it was difficult for him to subjectively judge how electricity was generated, he simply repeated the various experiments done by his predecessors when they explored electricity, and if the results of the experiments were consistent, he could judge that the properties of electricity in this world were the same as those in previous lives.

"Brother, what are you looking for?"

Jack, who was lying on the ground rummaging through the lockers, heard Remy's curious voice behind him.

"I'm looking for ...... Well, ah, found it!"

Jack took a piece of amber, picked up the silk that had been placed on the side of the cabinet, and turned around.

"I'm looking for amber and silk. ”

"Amber and silk?" Remy blinked cutely, her long eyelashes twitching, "what are you going to do with them?"

"Experiment!" replied Jack, thinking that this was not an educational opportunity for his sisters, "Where's Fran?"

"She was reading in the study......"

"Understand, come, follow me~"

The storage room was on the second floor, and Jack followed Remy to the study on the first floor.

When he pushed the door in, he saw that Fran was in a panic and covered the book in her hand and stuffed it into a drawer, which inevitably aroused Jack's curiosity.

"Fran?"

"Hmm...... Ah, brother, good afternoon!" Fran struggled to maintain her usual no-nothing and composure, but from her slightly trembling voice and lovely pale pink cheeks, Jack could tell the little girl's panic and shyness.

"What's wrong with you?"

"It's okay, brother, I was just reading a book. ”

Nodding, Jack wasn't going to dig deeper, he wasn't a guy who liked to explore other people's secrets.

"Come, Fran, brother will take you to see something good~" Jack beckoned to Fran and motioned for the little girl to come with him.

Seeing that Jack didn't ask any more questions, Fran breathed a sigh of relief, then pursed her pale pink lips, jumped off the high chair lightly, and trotted over to Jack.

"Brother!"

Jacqua grabbed Fran's outstretched hand, and then, holding one by one, led his two sisters to the practice room.

"Brother, what are you going to do?"

Remy watched as Jack dragged a small table, then mysteriously placed amber and silk on the table, and finally, he went to find a piece of papyrus and tore it to shreds.

"Remy, Fran, do you think we know anything about the world?"

"I understand~ I know best!" Remy's eyes lit up and he said triumphantly, "I know that there are springs, summers, autumns and winters every year, and I also know that as long as we continue to temper our will, we can temper our bloodlines and become knights." ”

"Stupid Remy, my brother obviously means to make us say that we don't understand!" Fran complained on the side, and although she said this, her expression seemed to think that she knew very well.

"Actually, Remy said very well, yes, we humans know the world very well, we can even use our own power to change nature, but we don't really know that much about the world, if we ask a few more why we will find our ignorance, why we humans can use magic, why does the sun rise in the east and set in the west? why do I ask why? Or ......" Jack picked up amber and silk and rubbed them against each other, then he gently brought amber close to the scrap of paper on the table.

"Oh!!"

The two little Lori cried out in surprise, and even Fran, who had nothing in the past, was full of surprise.

I saw that the ordinary, at most beautiful amber, had a suction power in vain, sucking up all the pieces of paper on the table.

The orange sunlight gilded the room with the heaviness of an oil painting, without any brilliant light and shadow, but the scene that clearly violated the attempt brought a visual impact to the two little loli, as if there was some kind of alluring mystery hidden in the oval amber and paper.

"Why is that?"

Jack had a mysterious and happy smile on his face, the mystery was to pretend to be a force in front of his two sisters, and he was happy because the experiment verified the basic property of electricity - friction can cause electricity - which was undoubtedly a good start.

"Why, why?" Remy curiously took the amber from Jack and looked it up and down.

"Brother, you used magic!" Fran, who was also confused, circled around Jack and the desk, as if trying to find evidence of his secret use of magic.

"It's a pity~ No! I don't use magic~ Remy, Fran, do you think it's magical?"

"Magical!" Exclaimed Remy excitedly, "It's so much more magical than magic!"

"Brother, tell us how we did it!" asked Fran curiously.

"Actually, you can try it yourself, come, rub amber and silk against each other, ah, wait, you have to go to the electricity first......"

――――

Jack and his two younger sisters had been in the practice room for an afternoon.

During this time, Jack did experiments on attractability, and on capacitance, that is, on a Leyden bottle, which verified the existence of conductors and resistances, and basically determined the possibility of the existence of electric charges.

Finally, Jack used a homemade voltage device to measure the fruit battery with lemon as the core, because zinc could not be found for a while, so Jack used the bright iron found in this world, magnesium strips and silver oxide as the positive and negative electrodes of the fruit battery.

After a series of experiments, both Jack and his two sisters were very excited, and even during dinner, they discussed these experiments.

"Brother, the glass bottle can actually make people feel numb, it's really amazing......" Remy held the dinner knife and shouted with interest, her face full of excitement.

"Brother, is there really a tiny charge in amber?" Fran seemed confused, holding the broccoli to her lips with a fork in her hand, but she couldn't put it in her mouth.

"Well, I'm not sure about that. Jack took a sip of orange juice in a good mood, "I've just made some conjectures based on the phenomena we've found, you see we can make them electrify by rubbing, obviously something is running from one object to another, of course, this is just a conjecture, if we want to test this conjecture, we need more rigorous experiments." ”

"But I've seen it, and there's nothing in it, either amber or silk!" asked Fran, desperately asking.

"There's a lot of things you can't see with your eyes, let's put it this way, Fran, can you see the magic?"

"Hmm...... Brother, it seems that you can see, I heard that the knights of the sixth level can see the magic power!"

"What are you discussing, and why does it sound so interesting?" asked Tifa curiously.

"Discuss the experiment that my brother did in the afternoon. Fran replied calmly.

"Brother doesn't use magic, but he can suck up paper!" Remy said vaguely, biting into the beef.

"Huh?"

......

The dinner party ended quickly.

Jack also returned to his room and sat cross-legged in meditation.

When he had just cleared his mind and entered the world of elementary meditation, he suddenly realized......

This mere elementary meditation seems to have produced a certain change.
