Chapter 154: Opening the Door to a New World!

Harof and Lynn pulled the thin rope taut together, one end pressed under the ice column, while the other end overlapped with the shadow.

When the magical clock struck exactly twelve o'clock, Harof used his hand like a blade and precisely cut the remaining rope!

"Ruler, hurry, pass me the ruler!" Harof shouted excitedly, so hurried in his descent that he forgot the most crucial tool.

Elok, with quick reflexes, immediately ran back to the airship and handed the ruler to Harof within ten seconds.

The legendary wizard took the ruler with great solemnity, as if on a pilgrimage, and began to measure the length in segments.

"Harof, what's the length of the shadow?" several accompanying wizards asked with great anticipation.

Harof didn't answer immediately but measured multiple times before speaking cautiously. "It's 1,051 centimeters, or 10.51 meters!"

With the data in hand, everyone quickly took out pen and paper to calculate. The wizards, who hadn't formally studied advanced mathematics, still knew basic geometry.

However, this value wasn't a whole number. With decimals, squaring and taking the square root doubled the calculation complexity. It took over five minutes for them to calculate that the length of the hypotenuse was approximately 100.55 meters.

After over two months of mathematical training, Lydia and Elok were clearly quicker than the rest. They had already started calculating the angles of the triangle, using trigonometric formulas to determine the sine of the opposite side over the hypotenuse.

"I've calculated it! The angle is six degrees!" Lydia, the first to calculate it, waved her arms vigorously and shouted loudly.

Harof, who didn't have pen and paper, also arrived at the answer through mental calculation at the same time. Lydia's calculation was correct; the triangle's apex angle and the corresponding angle on the Earth were indeed six degrees!

Meanwhile, in the city of Greenriel, a dozen alchemists were anxiously waiting by the communication alchemical array, hoping for news from the other side.

But it was already 12:37, and they hadn't received any messages, making Raphael and the others begin to doubt if the operation had failed. Could it be that Lynn's assumption was incorrect, and this continent wasn't spherical after all?

"Look, there's movement!" A sharp-eyed alchemist was the first to notice the alchemical array glowing. Everyone rushed over.

Since the distance was over 700 kilometers, the amount of mana required for transmission was a staggering number, so Rorl had only sent the two most crucial pieces of data: the shadow length and the apex angle.

"The shadow length is 10.51 meters, and the apex angle is 6 degrees..." Raphael, watching the data formed by magical energy inside the alchemical array, shouted excitedly.

Thanks to a sound-amplifying spell, this message quickly spread throughout Greenriel City. The entire city of wizards seemed to be in a frenzy as countless mages, who had eagerly anticipated this moment, took out parchment and quills to start their calculations. Even some educated civilians joined in.

Calculating the data with just the shadow length required a solid understanding of trigonometric functions, which was enough to baffle most wizards. However, once they had the apex angle, it became basic multiplication and division, something even some commoners could handle.

"The planet's circumference is 43,200 kilometers, the diameter is approximately 17,751 kilometers, and the surface area is 594 million square kilometers?" On the crowded streets of Greenriel City, Yal observed the just-calculated data, murmuring to himself.

He wasn't a wizard, or perhaps he lacked the aptitude, and never had the chance to become a wizard's apprentice. But, driven by a deep interest in mathematics, he had once thought that his math skills would only be useful for everyday transactions and, at best, make him a tax collector. However, the last issue of the "Magic Daily" had opened a new world for him.

A wizard named Lynn, who had come from beyond the Misty Sea, was planning to measure the circumference of their planet using just a few simple mathematical formulas, without the need for any magic!

Yal had doubted whether it could be that simple, but when these values were revealed on paper, all his doubts vanished. The overwhelming shock he felt couldn't be quenched, as if the world was unfolding beneath his pen!
