A beam of light so strong that it was difficult to look directly at shot out from the tiny hole. However, since there was no element in a vacuum to reflect light, the people present could not see the beam at all. They could only determine the trajectory of the light by the one hundred circular mirrors that lit up in the Wizard City.

“It appeared, it appeared!”

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

"Did you see when it arrived?" Pierce asked curiously. He blinked just now and didn't see clearly when the light reached the top of the tower.

"It seems like just a moment? It was too fast..." Alok shook his head. He didn't even blink just now and couldn't see clearly.

The vacuum area covering half of the city slowly faded away. Maintaining such a huge area was not an easy task even for great wizards and legendary wizards.

"How is it, any results?" Raphael flew back quickly from the XC area and asked hurriedly.

Glenn immediately turned his head and looked at Nancy, the witch who was responsible for recording time, and the magic clock in her hand.

The time above stopped at zero minutes and zero seconds...

Glenn frowned. Could it be that the other party forgot to start the timer? Such an important experiment, even the legendary speakers participated in it, how could such a big mistake occur...

"I...I pressed it!" Nancy said anxiously, almost crying, because the start and end happened almost at the same time!

This magic clock is an extremely sophisticated alchemical instrument. It stores the Sands of Time inside and is solidified with magic. Ten grains of sand fall every second, which means that the accuracy can reach 0.1 second.

Nancy's hand speed was obviously very fast, and she pressed the button in a very timely manner, so not a single grain of sand of time fell.

"Did you see it clearly just now?" Harof turned to look at Aurora and Vittorio. The two legendary speakers also shook their heads. They were also paying attention all the time, but still couldn't see it clearly.

Everyone present showed a look of horror on their faces. The light had traveled a distance of one hundred kilometers before appearing there. Even the legendary wizard could not detect any clues during the whole process.

So how fast is it? 10,000 km? 100,000 km? 1 million km?

"Can light really arrive instantly?" Sanchez speculated. This was also the theory of the infinite speed of light that was popular in the wizarding land before. No matter how far the distance is, it can reach the destination instantly.

If this is the case, then what is the point of testing the speed of light? No matter how you test it, there will be no results.

Aurora shook her head. She knew there must be a limit. She had made some progress in her astronomical research in recent days. In addition to Tyr, she could observe unstable orbital periods on the companion stars of many planets.

This must be related to the speed of light...it's just that this value may be beyond imagination.

"It seems that this experiment has failed!" Glenn sighed. Although he was very unwilling, he had to admit that they had done everything they could! They even managed to make light travel a distance of 100 kilometers. However, it seemed that this distance was no different from 100 meters for light. It arrived in an instant!

"I think this experiment has great value." Lin En's voice suddenly rang out. "At least it should be no problem to get a Morning Star Medal."

"Master Lin En, even if you want to be partial, you can't joke about the reputation of the parliament, right?" A great wizard said with dissatisfaction.

Glenn's plan to measure the speed of light using mirror reflection is indeed very interesting, but it is also a fact that no research results were obtained!

If this could be given as a Morning Star Medal, then everyone would have one!

Lin En didn't reply, but pointed at the first round mirror...

Everyone present looked over in confusion. Although the surrounding vacuum field had been removed, the magic of focusing light was still continuing. The beam of light with a diameter of less than one centimeter was shining on the round mirror, and wisps of hot steam were constantly coming out...

Click...

With a slight sound, the mirror suddenly shattered.

The energy contained in this beam of light was extremely terrifying. Even if the round mirror could reflect 99% of the light, the remaining 1% of the energy absorbed would exceed the threshold that the mirror could withstand! Without the barrier of the mirror, the power and terror of the beam of light were revealed without a doubt! A wizard standing in the back was hit by the beam of light, and his entire shoulder was instantly penetrated. A shrill scream suddenly resounded in the street, and the wizards gathered nearby immediately scattered in panic. However, the speed of light was too fast, and all this was in vain...

Glenn had not expected something like this to happen, but the core of the light was not something he could control, so he could only subconsciously deviate from the beam...

The tiny but powerful beam of light was like a divine sword of nearly infinite length, tearing apart everything that stood in its way. Half of the shoulder of the injured wizard was cut off directly, and then like a knife cutting into butter, it cut the wall behind him diagonally into two pieces, leaving a striking red burn mark on the ground. It was the scene of the floor tiles being destroyed and melted, and finally shot straight into the air.

Anthony reacted quickly and canceled his thunder magic. Without the powerful light source, the dazzling beam of light disappeared without a trace.

The chaotic scene on the field also subsided. Fulla wiped the cold sweat from her head. She was also in the attack range of the light beam just now, but when she saw it start to shift, she subconsciously lowered her head and avoided having her head cut off.

The astonishing temperature and destructive power still left a big shadow in her heart...

This sudden experimental accident caused more than ten people to be injured. The only thing to be thankful for is that no one died.

The two most unlucky ones, one had half of his shoulder cut off, and the other was hit head-on when the light deviated! Fortunately, the other party was cautious enough and cast a [Mage Shield] on himself when he got close to watch the experiment, but there was also a deep scar on his chest, and no blood flowed 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 only suffered burns or temporary blindness from the strong light, neither of which was life-threatening...
