With Minister Dean's assurance, Flandie was relieved that the tragic rules of Millaire would be a thing of the past, and no one would risk being burned to flint again.

After accompanying Minister Dean here, he returned to Ore Mountain, and there was still a lot of work left, and Flandy couldn't continue to bother, so he took his leave and left.

Back in the magic tower, he put on the ice silkworm cloak again, and then he directly opened the portal of the fire cave.

Let the large fire crystal go out on its own, and Flandy is going into the cave to find some smaller fire crystals.

This time, he didn't go too deep, starting with the smallest fire crystal, collecting as he went, until about a thousand meters later, he pulled out a piece of fire crystal of about one meter, and then he stopped.

In order to verify how high the temperature of his magic seed can withstand, he has been controlling the positioning magic seed floating outside his body while collecting fire crystals.

There was already a pale blue flame here, and the magic seeds floating outside the body were already a little unstable.

This is still Flandi's magic seed, and it is estimated that if it were an ordinary person, I am afraid that it would have been burned by the heat long ago.

The magic seed can indeed withstand this kind of high temperature, but when Flandi wanted to hide a positioning crystal here, as soon as he took out the crystal, he saw that the positioning crystal melted directly, and there was no chance to put it back.

"Forget it, there's no need to be here, it's a big deal to take a few extra steps every time you come. ”

Losing a mid-level Demon Crystal, Flandi was a little distressed and had to comfort himself like this.

When he went back again, Brandi learned to be obedient, and instead of going to the old office building to find Vice Dean Gavin, he went straight back to the second basement floor of his magic tower.

It's an open space, and the top, bottom, left, right, front and back sides are all cast from quartz-added Gaia steel, which is very resistant to magic.

After placing the fire crystal here, Flandy opened the portal and asked Vice Dean Gavin to come and retrieve it.

This was already discussed yesterday, and Vice President Gavin was also wearing an ice silkworm cloak when he came over, and after taking the fire crystal away, Flandi didn't care.

There are alchemists in the academy who are more knowledgeable than him, as long as they finish their research on the fire crystal, they can directly take the experiment report and read it.

At present, Flandy's focus is still on the application of electricity, and the generator has been made a small one, as long as the application is studied a few more, you can start a large generator set.

For electrical appliances, Flandi is too familiar, lights, telephones, remote telegraphs, motors, and even rice cookers, fans and other small household appliances, all need the support of electricity.

"Well, if only I could work on computers in my lifetime. Flandy sighed, but he knew it was a fantasy unless he lived to be as old as his teacher, Algernon.

Take the magic ladder and ascend to the seventh floor, and the test of the electric light continues.

Three days later, three of the seven test lights had been extinguished, and four were still as bright as new.

However, the time is still short, at least ten days of uninterrupted brightness, in order to reach the practical level.

Arriving at his workbench, Franky took a piece of paper and began to write with a quill pen.

"Tom, Jerry, give you both a mission. Brandy handed them the paper full of words.

"What is it?" Tom took the paper, and found that it was all ordinary material, but it was vaguely written.

"Here are some of the materials I need and I need you to get them ready as soon as possible. ”

Jerry looked at the piece of paper and let out a wail, "Oh my God, Flandy, do you want us to pull the copper wire again? And it has to be so thin?"

"Okay, okay, you don't have to pull it yourself this time, go and let the craftsmen of the craftsman's workshop pull the thread, this time it's more demanding. ”

"That's fine......" Jerry wiped a cold sweat.

"You tell them to prepare more copper wires for me, and they will need a lot in the future, and they will need some of all kinds of specifications, so as not to have them when they are used. ”

"Okay, as long as you don't let me pull. ”

The two of them happily took the paper and went to prepare the materials, these are not valuable materials, there is only a small part in the magic tower, and the rest need to go to the craftsman's workshop or the Ministry of Industry to find them.

"It's good to have an experimental assistant, and it saves a lot of work. Brandi thought to herself.

The design drawings promised to Minister Dean are very simple, just draw a rough drawing, and don't worry about the details, and the people in the Ministry of Engineering will naturally improve it.

After the drawing, Frankie thought about it again and wrote a small line at the end.

"If you need my fire-based magic seeds, come to me. ”

The reason why such a sentence is marked is mainly because Flandi is reluctant to use his high-grade magic crystals, there are not many magic crystals in his hand, and each one has an important use.

"Vice Dean Gavin said that fire crystals can also be used as demon crystals, but they can't be cultivated, and I don't know when they will be able to be studied. ”

After doing this, Franky began to draw a circuit diagram of a new object that he was going to study.

That's right, it's the circuit diagram, and he's already getting ready to make the phone.

Of course, it is a corded telephone, and the wireless telephone cannot be manufactured at all under his current conditions, and the technological upgrade needs to be done step by step, and there is no shortcut at all.

As long as the phone is made, many things can be derived, the most important is that the microphone and earpiece are the most practical.

The oldest telephones are actually not difficult, the vibration of the vocal cords excites the air to vibrate, forming sound waves, and then the sound waves act on the microphone, causing it to produce an electric current, which is then sent along the line to the receiver of the other party's telephone.

Frandy remembers that in his previous life, when he was in high school, he made a simple phone by himself, and although many parts were already made, the basic principles were the same.

He has tried his best to replace the materials of the telephone in his previous life with the materials of this world, and as soon as the prototype of the telephone comes out, it will still be thrown to the Imperial Academy of Sciences as a physical object for teaching.

It is believed that if those scientific researchers thoroughly study the principle and structure of the telephone, they will be able to derive more practical things.

At the very least, it is estimated that there is no problem in fiddling up a megaphone according to the principle of the telephone.

"Teacher!"

"Teacher, we're back!"

"Teacher, don't think we have any?"

Hearing the call of his three disciples, Flandy realized that it was already afternoon.

In the past week, the growth rate of Pedi, Cathy, and Muliel can really be described as fast, with hundreds of magic seeds condensing every day.

That is, because their magic seeds are still too weak, otherwise, in terms of the number of magic seeds, even level six or seven magic can be cast.

"Come back, let's go, I'll take you to continue meditating. Flandy was about to open the plantation portal, but Pedi tugged at the corner of his coat.

"Teacher, we want to eat sugar gourds! You haven't made them for us for a few days since we finished eating them last time. ”

"If you want to eat sugar gourd, this is easy to do. Flandy habitually wanted to call Tom and Jerry, but remembered that he had sent them in the morning to find materials.

"How did you get back?" asked Flandy.

"Mr. Tom picked us up, and he sent us back and left at once. ”

"Okay, then when you come back from meditation, the teacher will do it for you. ”

"Oh yes, great, Sister Cathy, I say, the teacher will definitely make us sugar gourds. Pedi was overjoyed.

"Let's go, if you finish absorbing the magic elements early, you can come back early to make sugar gourds. Frandy said, waving open the portal.

He would bring three disciples to the plantation every day to meditate, so the three of Peidi were already familiar with this place.

It didn't matter what Flandy commanded, Pei Di, Cathy, and Mu Lier each went to their own attribute magic grass and began to meditate.

It took more than an hour for the disciples to meditate at a time, and Flandi was not in a hurry, and it only took ten minutes to turn around the two attributes of the Earth System and the Space System Demon Gathering Grass, and he absorbed all the magic elements gathered today.

Looking at these soon-to-be-ripened demon grasses, Frandy couldn't help but sigh.
