The airship was moving faster than expected, and on the evening of the third day, a magnificent city appeared in front of Lynn.

That's the city of wizards, Greenriel!

The city is built between the mountains, the whole is round, like a huge gem inlaid between the mountains, the towering city wall is erected a large number of high-grade magic crystal cannons, I don't know what the principle, in the case of no one to control the spontaneous turn the muzzle of the cannon to the direction of the airship.

Lynn has seen the power of this thing, and it can even severely damage the powerful Eye of Death.

However, he didn't come to invade, he had already reported through the magic circle that transmitted alchemy, and there were two great wizards on the airship, Lynn was not worried about them being attacked, but looked straight at the towering spire in the middle of the city, shining with magic in the afterglow of the setting sun, which looked very eye-catching.

"Is this the Corona Tower?" Lynn muttered softly to herself.

Raphael nodded in response. "Yes, this is the Tower of the Corona, the symbol of the City of Wizards!"

"Master Raphael, may I ask why this tower is called that?" Lynn asked, after experiencing the incident of the harbor of Iyeta, he felt a little shadowy in his heart when he saw this kind of tall spire.

"Actually, it was supposed to be called the Tower of Eclipse or the Tower of the Shadowless, but because the meaning of these names is not very good, it was changed to Corona ......," Raphael explained.

Every year in mid-July, under the midday sun, the shadow of this magic tower will completely overlap with the base, forming a shadowless tower.

Of course, this was true of all the buildings in Greenriel that day, but the Corona Tower was very tall and the most impressive.

The calendar and hours of the Wizarding Land are also divided according to the length and angle of the shadow of the Corona Tower under the sun's rays, and it is a perfect 360 days, divided into 12 months, each month is no more and no less than exactly 30 days.

"Nice design!" Lynn said with a raised brow.

In this way, the entire tower is a giant clock.

As for the cause of the Shadowless Tower, he could guess that it was nothing more than the middle of July, when the tower was just at the point of direct sunlight.

While the two were chatting, the airship had already passed through Greenriel and landed in the square in front of the Magic Research Association on the east side, attracting a large crowd of wizards.

After all, everyone comes by horse-drawn carriage, and they are the most special.

"Is this an airship? It's even bigger than what you see in the newspapers......"

"It's really magnificent, if it's not expensive, it's a good choice to buy an airship for travel......"

The noisy discussion continued, in view of the hype of the previous [Magic Daily], Lynn and his airship have long been known to everyone, but the pictures are naturally not as shocking as the real thing, and those alchemists have even discussed the design principle of this alchemy instrument.

Being able to fly and levitate without wings is a kind of force field magic?

As a result, as soon as Lynn and the others got off the airship, they felt countless pairs of eyes staring at them, and it was obvious that they had become the focus of the audience.

Compared to Lynn, who was very calm, Jonny and Ellock, who arrived at Greenriel for the first time to participate in this grand event, were a little cramped.

Philip was dressed up, even when Master Herram led the team in the past, there were not many opportunities for their Iyeta school to show their faces like this.

At this moment, a tall, burly wizard with meticulously combed hair walked out of the crowd, bowed to Ogst and Raphael with a smile, and then turned to look at Lynn and the others.

"Mr. Philip and Mr. Lynn, welcome to Greenriel, please come with me!"

"Then, two masters, we'll see you tomorrow!" Lynn said goodbye to Ogst and Raphael, and then followed the tall wizard towards the Iyeta School's dedicated lounge.

After arranging the accommodation, Philip hurriedly pulled Lynn aside. "Tomorrow you've figured out what to do with those wizards of the Prophecy School?"

"Of course......" Lynn lengthened her tone, "no!" ”

Philip's whole person was messy, and when he saw Lynn's extremely calm appearance, he thought that he was already confident, but he didn't expect to be unprepared.

But before Philip could jump to his feet, Lynn spoke again. "If you can help me get the detailed data of the Star Map of the Prophecy School, then I can be sure of everything!"

"It's easy, you wait, I'll be back soon......" Philip hurried out the door, the wizards of the Prophecy School had published the results of these studies in the previous issue of the Magic Daily, and there were corresponding records in the library, it should not be difficult to find.

Lynn took out a piece of parchment from the table and wrote down the famous Kepler's third law and the law of universal gravitation......

If you want to understand the laws of the orbit of the stars, you need to make uninterrupted observations for tens or even hundreds of years, and it is definitely too late for you to do it now, but fortunately, those prophetic wizards have already helped him complete the most complicated work, and he only needs to verify whether the theory is correct.

……

At night, the wizarding city of Greenriel.

Lynn travels alone to the outside of Haroff's estate, ready to meet the legendary wizard of fame.

However, when he arrived at the door, he was surprised to find that the door was already crowded, and more than a dozen wizards were anxiously waiting in front of the door, each holding an envelope or manuscript in his hand.

Before Lynn could ask, the door of the manor opened, and out came a witch of about thirty years old, judging by the badge on her chest, she should be a three-ring wizard.

Almost at the same time, the crowd gathered around the door immediately crowded in.

"Theresa, this is the data that I have spent a whole decade researching, and I hope it will be helpful to Speaker Harrov's research." A tall, thin wizard pleaded and handed over a stack of manuscript paper in his hand.

Not to be outdone, the rest of the wizards rushed forward to explain their research results, hoping to attract Theresa's attention, and put their manuscript paper on top when they reported, and even attached a few magic coins and even a whole money bag to the manuscript paper.

Lynn then realized that she was not the only one who knew that Haroff was studying gravity and was ready to start in this area.
