143 - Sky Dome Tower

"Jenny, now that you've calculated the data of this planet beneath our feet, it should be quite easy, right?" Lynn looked at the group of wizard apprentices, smiling as he inquired.

Jenny and the others nodded enthusiastically. They now understood that when the professor gave that first lesson, he wasn't just boasting. Numerology could indeed calculate almost anything.

Once they knew the planet's circumference, it would be a piece of cake to calculate the radius, area, and even volume.

Inside the seminar, the wizards couldn't contain their excitement. There were only ten days left until mid-July.

In other words, in ten days, this continent beneath their feet, or rather, the entire planet, would be revealed to them.

"I can't believe how your mind works, figuring out such a unique method." Raphael marvelled.

Before Lynn's arrival, while the Wizard Lands lacked a structured mathematical system, most wizards had a basic understanding of geometric calculations. However, they had never thought that such a simple method could be used to calculate the planet's circumference.

This was true genius…

Facing the praises from the others, Lynn remained calm. After all, this method wasn't something he had come up with on his own. He had taken the idea from the "Father of Geography" in a past life, Eratosthenes, and made some adjustments based on the Wizard Lands' circumstances.

In his previous life, while researching historical records, Lynn had been amazed by Eratosthenes' genius-like thinking. He used fundamental methods to solve the most complex problems.

"Are there any specific requirements for where to place this pillar?" Harof couldn't wait to verify this hypothesis. If there were still ten days left until mid-July, he would act right away.

"The ground should be as flat as possible, and the distance from Greenville should be at least five hundred kilometers. For more accurate data, it's best if it's over a thousand kilometers. Our continent is massive, and one scale could be tens or even hundreds of kilometers. So, the farther, the better. The pillar should also be as high as possible for a clear shadow." Lynn pondered.

"So far…" Harof's brows furrowed.

In this way, it seemed impossible to verify within the Wizard Lands.

"There's a suitable place I've heard of. It's a tower that's several hundred meters high, located outside the Misty Sea. It could serve as the pillar." Suddenly, Ogest suggested.

The wizards present were surprised, wondering what Ogest was referring to.

On the side, Philip suddenly looked as if he had remembered something and exclaimed, "Master Ogest, are you talking about the Sky Dome Tower in the Holy City?"

Although Philip had never been to the Sekas Empire, he had heard sailors from Harbor Town and others mention some interesting things about the Misty Sea, including the Sky Dome Tower.

It was rumored to be the manifestation place of the Creator of Life, the Lord of Stars, and the Goddess of the Moon, Aila—the holy land in the hearts of all believers.

Regarding this so-called "god," Philip naturally scoffed, but he was aware of the power of the Church. If they went to the Holy City to measure the length of the Sky Dome Tower, they would be risking their lives. They would probably be unable to even enter the gates and would be burned at the stake.

But rational people like Philip were in the minority. Many young wizards were even clamoring to go straight to the Holy City.

In their eyes, the Wizard Lands were no longer the refuge for the exiled wizards it used to be. After hundreds of years of development, they had created countless new spells and established a system for wizard advancement and magical theories, making them incredibly powerful.

Lynn's portrayal of the celestial vision had made the wizards realize how vast the world truly was and how they were trapped within their little Wizard Lands…

However, Harof quickly poured cold water on their enthusiasm. "We only have ten days, and even if we set off now, we might not make it to the Sky Dome Tower in time."

"Moreover, there's no need to make it so complicated. We can simply create an ice island at sea using magic and erect an ice pillar on it. This way, the data we calculate will be the most accurate."

The side of the Wizard Lands facing the Sekas Empire was the Misty Sea, but that didn't mean the entire island was enveloped in mist. In fact, the sea beyond was navigable.

The only issue was that the sea was vast. Once, a great wizard had wanted to explore the other side of the sea and ended up flying for a month, only to find some uninhabited islands and ferocious sea creatures. He had almost lost his way back.

Under Harof's decision, the discussion didn't escalate to the point of storming the Sekas Empire and overthrowing the Church, despite the opinions of some wizards who believed that Harof's plan was too cautious.

Instead, the focus shifted to how to determine the distance between the Sun Crown Tower and the pillar.

A female wizard soon proposed a method: they could use an extremely long rope to measure the distance, marking the ground at every rope length as a reference. But this proposal was quickly rejected as being too troublesome, especially considering the uneven terrain in the Wizard Lands, which would introduce significant errors.

After a lively debate, the more convenient methods of using carriages and airships for distance measurement took the lead.

"How about using an airship?" Lydia suggested, raising her hand high.

Raphael and the others suddenly saw the light, as Raphael had been about to suggest the same thing, but Lydia beat him to it.

Compared to alchemical ships, which could be affected by wind and waves, an airship floating in the sky was undoubtedly a better choice. It could overcome all obstacles, navigate in a straight line, and, when enhanced with wind resistance magic, maintain a stable speed that wasn't easily affected by fluctuations.

If the airship traveled at full speed, it could cover fifteen kilometers per hour. So, at full speed, it would cover 360 kilometers in a day, providing a highly accurate way to measure the distance…

Lynn didn't participate in the discussion. Instead, he turned to the diviner from the various prediction schools, smiling as he asked, "Mr. Yulande, do you have any more questions now?"

Yulande remained stunned, his mind filled with Lynn's method of dividing the circle to calculate the circumference. Although they hadn't arrived at an accurate result yet, he understood that the divination schools had lost decisively this time.
