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 ovepped with the shadow.


    When the magical clock struck exactly twelve o''clock, Harof used his hand like a de 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 apanying 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 calcte. 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 calctionplexity. It took over five minutes for them to calcte 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 calcting the angles of the triangle, using trigonometric forms to determine the sine of the opposite side over the hypotenuse.


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


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


    The rest was straightforward. A circle had 360 degrees, so the Earth''s angle meant dividing the entire circle into sixty equal parts, each being 720 kilometers. So, the total length was...


    "43,200 kilometers!" Harof''s voice trembled, and he repeated the calction several times in his mind, afraid of making a mistake. After confirming it was correct, he said, almost in a dream, "43,200 kilometers! This is the circumference of our!"


    Lynn, of course, was the fastest to calcte. After receiving the shadow length data from the AI in his brain, he instantly had the answer.


    It seemed that this alien was slightlyrger than Earth in his previous life.


    If he remembered correctly, Earth''s circumference was around 40,075 kilometers, and the two values were quite close.


    The other wizards quickly calcted the same value, and they were all thrilled. Once they knew the circumference, calcting the diameter, radius, and surface area was only a matter of time.


    On the side, Rorl didn''t participate in the calctions. Instead, he created another new painting, titled "People Measuring the''s Circumference Under the zing Sun and Ice." His ink-dipped quill danced rapidly on parchment.


    Harof, using the ruler to measure the rope''s length, Lynn estimating the central angle, Lydia jumping with excitement, and the wizards in the background deep in thought all vividly appeared on paper. Against the backdrop of the harsh sun and floating ice inds, the scene was bizarre yet harmonious, forming a striking and beautiful picture.


    After pouring his inspiration onto the canvas, Rorl looked at the two paintings in his hand and felt that his life was nowplete. He was well aware that these two pieces would be remembered by people for generations toe during this historic moment.


    However, afterposing himself, Rorl didn''t forget about another crucial matter, as some people couldn''t wait any longer.


    Thinking of this, Rorl turned to Harof and asked, "Harof, should we send this message to Greenriel now?"


    Harof, who was calcting the''s surface area, didn''t have time to respond but simply nodded. "Now that we''ve confirmed it, send it!"


    Meanwhile, in the city of Greenriel, a dozen alchemists were anxiously waiting by themunication 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 calctions. Even some educated civilians joined in.


    Calcting 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 somemoners could handle.


    "The''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-calcted data, murmuring to himself.


    He wasn''t a wizard, or perhaps hecked the aptitude, and never had the chance to be 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, thest issue of the "Magic Daily" had opened a new world for him.


    A wizard named Lynn, who hade from beyond the Misty Sea, was nning to measure the circumference of their using just a few simple mathematical forms, 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!
