There were bursts of screams from the crowd. Fortunately, Harov did not let the experimental accident happen again. The flying roulette fragments were like sinking into a quagmire. Under the effect of the slow barrier, their speed became slower and slower, and finally they hovered in the air.
"What was the speed just now, Mr. Speaker?" Raphael asked excitedly.
"It's fifty-two revolutions per second!" Harov said confidently.
You can never go wrong with this value!
Raphael immediately calculated in his mind.
Seven hundred and twenty teeth times eight kilometers times fifty-two revolutions, that is...
Twenty-nine thousand five hundred kilometers per second!
When they calculated this number, the wizards showed disbelief on their faces, and they even started to wonder if they had made a mistake.
This is too fast...
No wonder they couldn’t find the trajectory of light no matter how they measured it before.
"Doesn't this mean that light can circle the entire Eternal Star seven and a half times in one second?" Witch Nancy suddenly realized this.
The circumference of the continent beneath their feet is only 40,000 kilometers.
"Isn't this a bit too exaggerated?" Sanchez frowned. Nearly 300,000 kilometers per second is no different from arriving in an instant within their cognitive range.
"Only such a fast speed is enough to travel through the vast universe..." Aurora reminded.
For example, from the sun to this eternal star, the closest point is about 1.4 million kilometers, which takes more than eight minutes even at the speed of light!
However, in the face of such a distance and speed, even these legendary wizards are as small as dust...
"So what we see every day is the sun from several minutes ago!" Lydia counted on her fingers and suddenly came to a surprising conclusion.
Yolande and other wizards of the prophecy school suddenly thought that they might be able to measure the distances between the planets and them through the speed of light. The speed of light is a cosmic ruler and an excellent reference that allows them to easily calculate various data that were difficult to evaluate in the past.
Of course, this premise is that they need to measure the speed of light in the vacuum of the universe...
Just as the wizards were shocked by the terrifying speed of light, Lin En was thinking about another thing in his mind.
The speed of light in the two worlds is so close...
Lin En thought silently in his mind. If the data in the intelligent brain was correct, the speed of light measured in the previous life was 299,792 kilometers per second. The difference between the two was very small. It was probably just due to the problem of measurement accuracy...
Does this prove that the two worlds exist in the same universe?
This is not impossible. Although the Federation had never discovered magic in the previous life, humans could not even fully control the tiny solar system. It was like a savage living in the desert who believed that the yellow sand on the ground was the entire world.
However, the vastness of the universe is far beyond everyone's imagination. Perhaps in some galaxy in the universe, there exists a magical substance called magic, or energy?
Of course, the similarities between the two worlds are so great that it is possible that this is the Earth in another parallel universe...
However, these conjectures are obviously not verifiable now, and Lin En did not spend too much effort on it. Instead, he used the gears with different numbers of teeth that he had prepared long ago to try it again several times to verify the accuracy of the experiment.
There was some fluctuation in the final data, with a difference of about several hundred meters.
The wizards present were extremely satisfied with the result. After all, compared with the huge size of the speed of light, it is not worth mentioning at all.
Some people even speculate that the speed of light may be different in different areas, just like the speed of sound, so the data measured several times may vary.
Only Lin En himself was a little dissatisfied. Of course, the more accurate the measurement of the speed of light, the better. However, with the current simple conditions, it is impossible to make a more accurate instrument in a short time. The only thing that can be done is the gear and octahedron experiment. These two methods are convenient and easy to use, but slight errors are always inevitable.
Chapter 326: The Imperial Griffin Knights crossed the border!
After the speed of light measurement experiment was completed, this year's academic seminar finally came to an end, but the method of using gears to measure distance is still talked about with great interest.
What followed was an award ceremony held in the Sky Realm, where the three nominated people, Fulla, Glenn and Yolande, all successfully received the Morning Star Medal.
Lin En also won another Silver Moon Medal for his light speed measurement experiment!
However, regarding this awards ceremony, the wizards were extremely divided.
Most wizards think that the light beam measurement method proposed by Linn can only be described as a wizard!
Although this one experiment alone is far from meeting the requirements for obtaining the Silver Moon Medal, it wouldn't be a big deal to be a little more lenient towards geniuses.
Not to mention that the other party has even won the Corona Medal, so it won’t cause jealousy.
However, some wizards were dissatisfied with the fact that this magic star was awarded the Silver Moon Medal. Although Lin En's experiment was very exciting, even amazing, the final result was just to measure the speed of light.
This medal is usually only awarded to those who have made outstanding contributions to the wizarding land, developed legendary magic, or made important additions to the existing magic system.
In their view, the speed of light measured obviously does not correspond to any of them. It can be said that the parliament has made a very bad start this time...
As the center of the torrent, Lin En did not focus on gaining praise or refuting slander. He continued his research on basic elements. Occasionally, he was pulled out by Raphael and others to get acquainted with the great wizards stranded in the Wizard City.
Lin En did not refuse the communication between great wizards. These people were the best among wizards. Some of them had won the Morning Star Medal or even the Silver Moon Medal many times. In a sense, they were the Newton and Einstein of another world, and the backbone of the development of magic.
On the third day after the academic seminar, all the members who stayed in Greenrail City received invitations from the parliament. Lin En was no exception. He knew that the purpose of this meeting was probably to discuss how to deal with the massive invasion of the Holy See...
However, just before Lin En went out, Darren, the half-orc who should be far away in Yieta at this moment, came running over in a panic with his men.
"Master Dean, something bad has happened, something bad has happened!"
"What's wrong? Darren?" Lynn frowned, already having a guess in his mind.
"It's information from the Kingdom of Hadrata... Just yesterday morning, the imperial army suddenly crossed the border!" Darren said breathlessly, handing over a sealed letter.
This was much faster than he had expected... Lin En pondered and opened the envelope directly. After reading it, his expression suddenly became very solemn.
……
A day ago, at the border of the Kingdom of Hadhrata, two huge airships were hovering a thousand meters in the air on a routine patrol.
As a glorious airship pilot, Hami has dreamed of flying freely in the sky like a bird since he was a child.
However, as he had no talent for magic, he knew very well that it was an unrealistic fantasy. A hoe and a piece of farmland were the foreseeable future for him. If he was lucky, he might even be able to buy a camel, which would save him some effort when farming.
But everything changed since the new dean arrived in Yieta two years ago!
Hami put down his hoe and joined the newly opened glass workshop, because he could earn in one month what he used to earn in half a year. Later, he heard that the dean planned to recruit some civilians and train them to be airship pilots.
Hami couldn't believe his ears when he got the news. In his opinion, these airships, which were bigger than a house but could rise into the sky, were the greatest magical creations of the wizards.
It is a great blessing to allow them to spend money to experience it.
Can these civilians who don't know magic also control such amazing magical creations?
However, despite his confusion, Hami immediately quit his job in the workshop and joined the driver training.
In addition to figuring out how to control this behemoth and understanding this magical alchemical instrument that always points to the north and south, you also need to learn counting and Olympiad mathematics knowledge.
For example, how to estimate the distance between the airship and the target through appropriate reference objects and some "simple" formulas, and this is only the most basic reconnaissance subject.
Poor Hami had spent most of his life hoeing the fields, so naturally he was confused by what he was learning. According to some gossip, even some wizards found this so-called Olympiad mathematics difficult...
These efforts obviously brought him extremely generous rewards. His monthly salary increased from ten silver coins to twenty. He no longer needed to work day and night in the factory. His long-cherished dream was realized in another way!
So when he heard that Dean Lin En was going to select some airship pilots to carry out dangerous missions, Hami chose to participate without hesitation.
Half of it was to repay the dean's kindness, and the other part was because during the mission, the remuneration would be doubled. If they died accidentally, their families would receive a pension of ten magic gold coins, and would receive the best care in the future, and could even go to civilian schools for free.
Hami and the other pilots undoubtedly carried out the mission with the mentality that they would die, but after wandering around the border of the kingdom for more than a month, their tense minds gradually relaxed, and they even felt that what the wizard said might be a little too exaggerated.
They were thousands of meters in the sky at the moment. They only needed to see the empire's troops crossing the border from a distance, gather intelligence with binoculars, and then return to Yieta to report. What danger could there be...
However, during this month, Hami felt bored from patrolling back and forth in the same area. Although he liked the feeling of flying in the sky, he became a little bored of flying in the same place for a long time.
Hami fantasized in his mind, if only he could fly to the other side of the world to take a look...
"Wait, Hami, what do you see over there?" The deputy next to him suddenly shouted loudly as if he had discovered something.
Hami immediately turned his head and looked over. In the distant sky, there seemed to be a golden cloud floating towards them.
Why does it look so strange...
Hami used the telescope mounted on the airship to observe, and then his pupils shrank. This was not a cloud, but a large group of monsters with eagle-like heads and fire lion-like hindquarters. The bright golden eagle feathers showed a golden halo under the sunlight. From a distance, it looked like a cloud moving...
That's a griffin, the Empire's Griffin Knights!
Chapter 327: Damaged Airship and Air Battle at the Border
There are no such things as griffins in the wizarding land, but before leaving, the wizard masters had told them about the intelligence of several special military regiments in the empire, and the Griffin Knights was one of them.
"Retreat, retreat quickly!" Hami shouted loudly, and his deputy immediately turned the direction of the airship and fled towards the kingdom, and pressed the optical invisibility button as soon as possible.
A spherical shield immediately appeared around the airship, and the huge airship quickly disappeared in a distorted light.
The griffins following behind all let out sharp howls, but they did not run around in a panic as Hami had expected because they had lost their target. Instead, they sped up again and surrounded him in a very orderly circle, more than twice as fast as before...
"Damn, these guys are too difficult to deal with. Even my invisibility can't fool them!" Hami cursed inwardly.
He had only a limited understanding of griffins and didn't know that these magical creatures had a very high sense of smell and could even smell the blood of their prey from several kilometers away. Simply disappearing from sight would not cause much of a hindrance to them, not to mention being invisible right in front of them...
However, this cannot blame Hami and others for not being cautious enough. Although the polarizing magic added to the airship is easy to use, the amount of magic power consumed in hiding such a huge creature is not a small amount, and it can only be used at the critical moment!
Taking into account the possibility that they will need to stay in the outside world for two or three months, these drivers would of course try to save magic crystals as much as possible on a daily basis. It is impossible for them to be so extravagant as to use invisibility magic all the time to carry out missions!
"Hurry, hurry, hurry..." Hami and others raced against time and quickly pulled the joystick to the maximum. After the huge airship completed the difficult change of direction, a large amount of magic power was converted into hydrogen, and the internal combustion engine ran at full power!
The rest of the crew members held their guns tightly in their hands, but they did not fire rashly because the distance was too far.
The speed of the airship was getting faster and faster. The Griffin Knights, who had already closed the distance and were even vaguely surrounding it, were surprised to find that this huge thing that looked like an airship had actually exploded at a speed that exceeded the speed of the Griffin flying through the air...
Devi, the captain of the Griffin Knights, also did not expect this. In his opinion, such a huge alchemical instrument should run slowly, but the speed of the airship was unexpectedly fast...
If this continues, they will have no choice but to watch the other party slip away right under their noses...
Devi's eyes were very cold and stern. From this brief contact, he had already listed this strange alchemical creation as a major threat that must be eliminated!
Devi knew very well how much of a role a flying object that could carry people, was invisible and had an extremely high speed could play in a war!
We must keep the other person here!
And it would be best if we could intercept this alchemical creation as intact as possible!
Thinking of this, Devi immediately lowered his head and communicated with the griffin under him, and roughly estimated the direction and distance of both parties. It was in the northeast direction, about six hundred meters away!
This is a height that a bow and arrow cannot reach, but Devi is full of confidence because before becoming a Griffin Knight... he was a priest!
