Glenn's beam-measuring experiment, although ultimately a tragic failure, pushed the wizards' curiosity about the speed of light to another climax.

Because the results of the experiment shocked them too much, the terrifying power of condensing the bright light into a beam also made every wizard talk about it.

It is foreseeable that optics will become the direction of many wizards' research in the future.

However, the wizards were divided into two camps when it came to measuring the speed of light, with some insisting that the speed of light was infinite, after all, they could see the sun and moon at a glance, which were immensely far away.

Measuring the speed of light is nonsense!

Others believe that the speed of light is finite, because everything has that limit, and the 'light element' is no exception, but they can't think of continuing to experiment.

For light, even a distance of 100 kilometers is instantaneous, if this thing has speed, then it is at least more than 10,000 kilometers per second, so that everyone can react, you must know that the circumference of the eternal star under their feet is only more than 40,000 kilometers!

"Is it possible to conduct experiments on opposite sides of the planet?" The idea came to Sanchez's mind, so the field was big enough, so how would they get there?

"Fool, this planet is round, and the light travels in a straight line, it will either be blocked, or it will fly into the universe, but it will not reach the other side." Raphael said with a sneer.

"So what else do you say?" Sanchez asked annoyedly.

Raphael opened his mouth, then shook his head helplessly. "How do I know that?"

There are so many ideas for this magic star that before last year's magic seminar, who would have thought that the circumference and volume of the entire planet could be calculated just by standing an icicle on the surface of the sea and measuring the length of the shadow......

So Raphael couldn't guess what new ideas the other party would be able to come up with this time......

Curiosity is curiosity, this magic seminar will continue, and after three full days, a total of three winners of the Order of the Morning Star have appeared.

They are Glenn, who conjures up the magic of concentrating light, Furla, who takes the stage on behalf of Anthony to explain the theory of electromagnetism, and ......

Yoland, who made a rudimentary microscope...... After being refuted by Lynn at last year's seminar, this prophetic wizard learned from the pain and threw himself into his research.

While using an astronomical telescope to observe distant stars, Yolande suddenly made some improvements to this thing, and succeeded in getting a microscope.

Although the two had a-for-tat confrontation at the seminar a year ago, Lynn didn't take this little contradiction to heart, it was nothing more than an academic dispute, no matter how fierce the quarrel was, it was normal, and the other party didn't deliberately engage in some inferior means to disgust himself, so Lynn was still very generous to give the nomination of the Order of the Morning Star of Yoland.

This kind of generosity, on the contrary, made Yolande feel ashamed.

He was ready to be targeted this time, and even wrote a speech of tens of thousands of words in advance to explain the importance of this research, but he didn't expect that it would not be used at all, and Lynn was the first judge to propose to award him the Morning Star Medal.

In the past few days of working together, Raphael kept knocking on the side, hoping that Lynn could reveal some details, but he was blocked by the latter's boundless approach...... I could only murmur secretly, could it be that Sanchez's guess was right, and this magic star was not completely sure about the experiment, so he kept it secret.

Lynn ignored the rumors that had spread in the Wizarding Lands, and when he returned to the Iyeta School's common room, he summoned Elok and the others to ask them about their preparations.

"Dean Lynn, you've made all the gears ready!" Alok and Peirce spoke wearily.

It took them three days to make ten gears of the same size, ranging from 500 teeth to 1,200 teeth, and according to the instructions of the dean, the accuracy must be guaranteed, and the distance between each tooth is exactly equal, and the accuracy can reach one thousandth of a centimeter.

Only official wizards can do such delicate work, which is why Lynn brought them in on purpose - after all, someone has to do the work!

Lydia and Jonny, on the other hand, were in charge of the half-lens and mirror, both of which were now completed.

"Very good, it looks like we can start the experiment tonight!" After Lynn checked the various experimental supplies, she nodded with satisfaction.

Elok and the others are extremely strange, what did the Dean ask them to make so many gears?

"Do we need to rely on these things to measure the speed of light?" Lydia asked, raising her hand.

"Yes, the gears are enough!" Lynn nodded.

……

At night, inside Greenriel City, wizards who had received the news and had come to watch the experiment filled the entire square.

With the name of the Magic Star, coupled with the light-speed measurement experiment, no one wants to miss such a pageant.

"Master Lynn, we've been waiting for a long time, so you're not going to sell it now, are you?" Raphael said helplessly, he has been thinking about what other methods can be used to conduct experiments for the past few days, but he has no idea what.

"My method is simple, and everything you need is here!" Lynn said with a smile.

Raphael and the others looked curiously at the experimental device in front of Lynn, the most conspicuous thing was naturally the strange-looking alchemy instrument, after Lynn's explanation, they realized that this thing was used to shoot light beams, and the principle was similar to Glenn's concentrating magic.

A mirror is placed on the walls of the DC district, just four kilometers away from this square......

"Isn't this the mirror that Glenn did the other day to measure the speed of light?"

Nancy muttered softly, and the wizards present nodded in unison,

You must know that Glenn used a hundred mirrors to create a range of 100 kilometers, but in the end it still ended in failure, and although the mirrors set up by Lynn crossed most of Greenriel City, even if you count the distance between the round trip, it is only eight kilometers, less than one-tenth of it.

Measuring the speed of light is a fantasy!

"So I need to add this!" Lynn gestured to what Erok was holding. "That's the most important part of this experiment!"

"Cogs?" Raphael recognized it at a glance, this thing was not new to alchemists, and it existed in the steam engine made by the Alchemy Society before.

What does this have to do with the measurement of the speed of light?
