The mage of the Mage Parliament first brought Jiang Xiao to the middle level of the Mage Tower, and saw the prototype of the magic energy ranging tower on the spot.

As the "tower" of the source of the ranging magic, it is actually a huge wave energy magic guide stone. It will launch a slowly weakened magic to the surroundings at a fixed frequency. Another kind of magic guide in the distance can sense this.

The unique magic power of the magic guide is calculated based on the strength of the magic power.

Rag Box, who has developed this ranging magic master Lag Box, personally talked to Jiangxiao to demonstrate the results. He was holding a magic guide inlaid with the magic guide stone, and slowly stayed away from the source of the magic.

The number of metal roller -made roller continues to roll. After the Lag stopped, the drum stopped rolling, and it clearly showed that the distance was thirty yards.

At the same time, there is a precise ruler engraved on the ground.

After the demonstration was completed, Lag passed the magic guide to Jiang Xiaoxiao, and proudly said: "This magic guide will actively absorb the user's weak magic. Even ordinary people who have not received any spell training can use them.

. ""

Jiang Xiaotan looked at the exquisite magic guide in his hand, paced in the room, and looked at the distance displayed above constantly changing.

"So, how long is the maximum effective distance of the magic source?"

"The biggest effective distance in theory is the distance that the magic source is weakened to the degree of the extent that the ranging magic guide is not perceived. According to my calculation, the magic source of a mage tower is weakened to that level of flying 800 800

Wancodes. "

"It's amazing."

Jiang Xiao talked about estimation. From Constantin to Sipples, it was about 80,000 yards. The effective distance of the magic source reached 100 times the distance.

In this way, a ranging tower can cover most of the mainland.

"So the magic source launch magic power, is there a lot of loss for magic power?"

"A low -level energy storage rune stone can allow the magic source to run for about a month."

"This is really efficient." Jiang Xiao said admired.

This level of magic consumption is more energy -saving than his airship.

Conversion, about one -tenth of a month.

After the field inspection was inspected, after the high -efficiency magic ranging tower, Jiang Xiao talked about and the party came to Zhan Xingtai as the masters. Here are always places for high -level masters to hold a meeting.

Here, they will discuss how to plan the construction of the magic source tower and the establishment of a global coordinate system.

Because the content of this discussion has nothing to do with Sophie, and she was not good at talking, although she sat at the master's seat, Sophie was in a daze at the table.

In her mind, a small chessboard has been "projected", and two villains wearing black and white armor are trying to kill.

Lag Box talked eagerly with Jiang Xiao. Originally, he was not optimistic about the prospects of Magic Ridging, but Jiang Xiao's various theories were put forward, which made his inventor suddenly open up.

"So, we need to establish a set of intuitive coordinate system corresponding to the map. For example, we can call the horizontal axis of the east -west direction as longiture, and the vertical axis in the north and south is called latitude."

Jiang Xiao talked about a map of the latitude and weft line that he was prepared.

"But how do you convert the ranging data you get into the latitude and weft coordinates?" Sophie's mother Emma asked.

"It seems to need more complicated calculations ...." Lag Box said.

"Uh, it's not very complicated? Just set the formula." Jiang Xiao talked.

"formula?"

"Basic geometric formula, sine formula, Yu Xian formula or something."

"What is that?"

This problem made Jiang Xiao's conversation depressed again.

It stands to reason that he is facing the smartest group of people in the world, but he did not think that these wise masters did not even have basic geometric knowledge.

So he started from the most basic Pythagorean theorem and gave the masters a basic geometry.

However, the intelligence of these masters is indeed the top. Jiang Xiao talked about not a professional teacher, but the master of the masters basically penetrated his theory and formulas.

Even Sophie, who has been walking away, heard how to learn how to seek the angle of the triangle, and then calculate the coordinates.

And her calculation speed is amazing, and she is very accurate.

As a self -closed girl who does not like to speak, she can also become the chief master, and naturally has a place.

After some teachings of Jiangxiao, the masters also fully understood the benefits of establishing the latitude and weft coordinate system.

"It turns out that as long as you can master the coordinates of various cities, an experienced captain can not look at the Haitu, and determine which direction should be sailing." Emma wrote and painted on the paper in front of the paper with a feather pen.

Sigh, sigh.

"Earl Capler, this 'geometric science' you are talking about is really amazing. I think people should open a special" geometric "discipline at the Paris Magic Academy. Let the young mage learn this deep theory, it must be

Can deepen their understanding of magic. "Lag Box said.

"Ah ..." Jiang Xiao talked a little helpless.

If you want to teach science at the School of Magic, you are really a genius.

However, in this world, magic is also a "science".

What surprised him most was that Sophie, who had been unreachable, suddenly raised his hands and said: "Agree."

The meaning of the chief master is to agree with the "geometry" discipline in the Paris Magic Academy.

In this way, in the future, a mage who graduated from the School of Magic went out to find a job. People asked: "Which is the magic of what will be?"

Then the mage replied: "I can geometry, I am best at the rules of the ruler."

It's embarrassing to think about it.

Jiang Xiao talked about helping his forehead and said, "Let's go back to the topic first, about our global positioning system."

The establishment of the coordinate system only solves the most basic problem, and there are many problems to solve it.

"In the opinions of His Majesty's His Majesty's VII, we were originally going to establish three magic sources towers in Aichen, Matser, and Cypler.

The positioning service. But this is just our original goal. In the future, we will arrange the magic source tower to the global, and the layout of the magic source tower efficiently is the most important. "

What to do is actually very simple, that is, in any corner of the world, it can be covered by three magic sources towers to provide accurate positioning.

"This requires a lot of calculations. I think these days will become the main topics and my main topic."

Jiang Xiao said that he hadn't finished saying, but heard Sophie said: "No."

She waved her hand, and a few chess pieces flew out gently, and then fell on the map in front of Jiang Xiaotan.

Including the three points of Aichen, Marceri, and Ceipler, a few chess pieces were evenly scattered to the entire world map.

Jiang Xiaoxiao looked at it for a while, and then he couldn't hold his mouth in surprise.

Sophie's seemingly throwing a pawn is actually a precise calculation, which perfectly achieves at least three magic towers on any place on the map.
Chapter completed!
