After the vacuum field gradually formed, Glenn also unleashed his concentrating magic again, and the electric balls that flickered in mid-air were enveloped.

A beam of light that was so strong that it was difficult to see directly flew out from the tiny hole, but because there were no elements to reflect in the vacuum, everyone present could not see the existence of the beam at all, and could only judge the trajectory of the light through the hundred round mirrors lit up in the wizarding city.

"Appeared, appeared!"

The wizards waiting outside the vacuum field looked at the tower in amazement, although the incomplete reflection of the mirror would attenuate the intensity of the light layer by layer, but this time the light did not disappear after passing a full hundred kilometers, but illuminated the top of the tower and the entire white cloth.

"Did you see when it arrived?" Peirce asked curiously, he blinked just now, and he didn't see exactly when the light reached the top of the tower.

"Like in a moment? It's too fast......" Elok shook his head, he hadn't blinked at all but hadn't seen clearly.

The vacuum that enveloped half of the city was slowly receding, and maintaining such a large domain was not an easy task even for archwizards and legendary wizards.

"How's it going, is there a result?" Raphael flew back from the XC area quickly, and hurriedly asked.

Glenn immediately turned to Nancy, the witch who was in charge of recording the time, and the magic clock in her hand.

The time above is stuck at 0 minutes and 0 seconds......

Glenn frowned, could it be that the other party forgot to start the timer?

With such an important experiment, even the legendary speakers were involved, how could there be such a big flaw......

"I ...... I pressed! Nancy said in a hurry, and even cried urgently, because the beginning and the end were almost at the same time!

This magic clock is an incomparably sophisticated alchemical instrument, which stores the sands of time, and is solidified with magic, which is guaranteed to drop ten grains per second, which means that the accuracy can reach 0.1 seconds.

Nancy's hand speed was obviously also very fast, and she pressed it extremely timely, so not a single sand of time fell.

"Did you just see that?" Harrov turned his head to look at Aurora and Vittorio, and the two legendary Speakers shook their heads, both of them were always paying attention, but they still didn't see clearly.

Everyone present had a look of horror on their faces, but the light had traveled a full hundred kilometers before it appeared there, and even the legendary wizard could not even detect the slightest hint of the whole process.

So how fast is it, exactly? 10,000 km? 100,000 km? Or a million kilometers?

"Could it be that the light really arrived instantaneously?" Sanchez guessed that this was also the infinite doctrine of the speed of light that had prevailed in the Wizarding Lands before, and it could reach its destination in an instant, no matter how far away it was.

In that case, what is the need to test the speed of light, no matter how you measure it, there will be no results.

Aurora shook her head, she knew that there must be limits, and that she had made progress in astronomy these days, and that in addition to Tyre, the phenomenon of unstable periods could be observed on the companions of many planets.

This must be related to the speed of light...... It's just that this number may be unbelievably larger.

"Looks like this experiment has failed!" Glenn sighed and said, even though he was very unwilling, he had to admit it, they could be said to have done everything they could!

even succeeded in making the light pass through a distance of 100 kilometers, but now it seems that this distance is no different from a hundred meters for the light, it is all instantaneous!

Glenn was ashamed, he didn't expect that he had put in so much effort, and he had received the help of a group of great wizards and legendary speakers, but he had found nothing.

"I think this experiment is very valuable." Lynn's voice rang out suddenly. "It's okay to get at least one Morning Star Medal."

"Master Lynn, even if you want to take sides, you can't joke with the reputation of the council, right?" A great wizard said dissatisfied.

Glenn's plan to measure the speed of light with specular reflection is indeed very interesting, but it is also true that there are no research results!

If this can be given to the Morning Star Medal, then this thing is one for everyone!

Lynn didn't reply, but reached out and pointed to the first round mirror......

Everyone present looked at it in bewilderment, although the surrounding vacuum field had been removed, the magic of concentrating light was still continuing, and a beam of light with a diameter of less than one centimeter was shining on the round mirror, constantly steaming wisps of heat......

Click......

With a soft sound, the mirror suddenly shattered.

The energy contained in this beam of light is incomparably terrifying, even if the round mirror can reflect nine out of nine percent of the light, the remaining one percent of the absorbed energy has already exceeded the threshold that the mirror can bear!

Without the barrier of the mirror, the power and horror of the beam are undoubtedly revealed!

A wizard standing in the back was unlucky enough to be hit by a beam of light, and his entire shoulder was pierced in an instant, and a terrible scream suddenly resounded in the street, and the wizards gathered nearby immediately scattered in a panic, but the speed of the light was too fast, and all this was useless......

Glenn didn't expect such a thing to happen, but the core that made up the light was not something he could control, so he had to subconsciously deviate from this beam......

The subtle and intense beam of light was like a divine sword of almost infinite length, tearing apart everything that stood in front of him, and the injured wizard was directly cut off half of his shoulder, and then cut the wall behind him diagonally into two pieces like a knife into butter, leaving a striking crimson burn on the ground, which was the scene of the floor tiles being destroyed and melted, and finally shot straight into the air.

Anthony, who reacted, hurriedly canceled his thunder magic, lost his powerful light source, and the dazzling beam disappeared without a trace.

The chaotic scene on the field also subsided, and Fura wiped the cold sweat on her head, she was also in the attack range of the beam just now, but when she saw that this thing began to shift, she subconsciously lowered her head, so that her head was not cut off.

The astonishing temperature and destructive power still left a lot of shadows in her heart......

More than a dozen people were injured in this sudden experimental accident, and the only thing that is fortunate is that no one was killed.

One of the unlucky two had half of his shoulder cut off, causing one to be hit head-on when the light was off!

Fortunately, the other party was cautious enough to bless himself with a [mage shield] when he got closer to watch the experiment, but there was also a deep scar on his chest, and there was no blood flowing out of it, because the wound was directly coagulated by the high temperature.

The rest were lucky enough to be hundreds of meters away from the beam, and the burns, or the temporary blindness of the bright light, were not life-threatening injuries......
