Harrov thought for a long while but could note up with any results, so he finally sighed and looked towards Trisha, asking a question.


    "Where is today’s research material?"


    "Here, Teacher." Trisha respectfully handed over a stack of manuscript papers.


    Harrov casually picked up a piece of parchment and began to read it. Although the various ideas proposed by these formal wizards were full of loopholes, their wild and imaginative nature sometimes provided him with faint inspiration.


    After all, that was exactly what he wascking at the moment.


    Harrov scanned through them line by line and quickly tossed them aside, then picked up the next piece of parchment and began reading again.


    After reviewing a dozen or so pieces, Harrov’s patience had gradually worn thin.


    This issue’s theoretical quality was really poor, with many theories having no factual basis at all, merely fruitless daydreaming.


    It was simply a waste of his own time!


    Still, he decided to finish reading them all—what if he could find some inspiration?


    Harrov shook his head, clutching to ast glimmer of hope, and picked up an exceptionally elegant envelope that remained on the table.


    "Next time tell them just to bring manuscript papers, there’s no need for all these unnecessary decorations." Harrov said discontentedly.


    "Yes, Teacher. I’ll remind them," Trisha quickly nodded, her disdain for that man from outside Wizard Land named Lynn growing, as he was the one who had brought the envelope.


    "Hmm?" Harrov absentmindedly opened the envelope, and his whole person froze.


    For the envelope did not contain research papers filled with magic theories but an invitation.


    [Dear Esteemed Legendary Wizard Harrov,


    We hear you are studying thews governing the movement of stars and are dedicated to deciphering the secrets of gravity, space, and time. We hereby invite you to join the Secret Magic Society and together discuss the mysteries of the universe…]


    Harrov frowned deeply; he did not know how many such invitations from academic discussion organizations he had to reject each month, and now one had been mistakenly mixed in with his research materials.


    "I am very sorry, Teacher, it was my fault; I should have reviewed them beforehand," Trisha responded anxiously, revealing that her task had been dyed somewhat.


    "The Secret Magic Society..." Harrov did not immediately throw the letter away, as it seemed he had heard the name somewhere before. "Who brought this letter?"


    "It was a wizard named Lynn, that man from the Mist Sea who proposed theary theory," Trisha said with some resentment. "That arrogant man also imed he brought threews and a form that could solve the problems you’ve been facing."


    "Where are thosews and the form?" Harrov continued to ask.


    This wizard organization, having clearly proposed theary theory and thew of free fall, must have something of substance; it wouldn’t hurt to look!


    Trisha momentarily choked up and struggled to speak…


    Fortunately, Harrov quickly found the form andws Lynn had written on the backside of the invitation.


    [First Law: Alls move in elliptical orbits around a star, and the star is at one of the foci of the ellipse.]


    As Harrov’s eyes swept over the first line, he nodded thoughtfully.


    Indeed, while studying the motion of the stars, he had also observed this phenomenon, but the question was why it was so. ording to his hypothesis, the gravity field should be a perfect circle, with the star positioned at the center.


    This was one of the issues that had always troubled him.


    So, Harrov hurriedly looked down, but what was unexpected was that there was no exnation whatsoever; instead, the text directly proposed the second and thirdws.


    [Second Law: For any, the area swept by the line connecting it with the star is proportional to the time of motion, and the’s velocity at perihelion is constant.]


    [Third Law: For allary orbits, the cube of the semi-major axis of the orbit is proportional to the square of the period of revolution around the star, and the ratio is only rted to the celestial body it orbits.]


    Harrov’s expression immediately became serious because these were two entirely newws that even he had not yet discovered.


    "Quick, bring paper and pen, I need to verify this," Harrov called out loudly.


    Could these so-calledws really be useful to his mentor? Trisha felt a vague unease in her heart and even more so, did not understand why merely three sentences had caused Harrov, a legendary wizard, to behave so unusually.


    Thoughpletely baffled, Trisha quickly brought over the paper and pen.


    But Harrov, who couldn’t wait, directly started writing and drawing in the air with magic power, then took out the star maps’ data and beganparing each one.


    Trisha stood by with the paper and pen, holding her breath in fear, and just stayed there waiting for several hours.


    Only when the sky began to brighten did Harrov stop, looking at the star orbit data floating in mid-air and muttering to himself.


    "It matches, it really matches!"


    Harrov felt he had never been closer to the truth.


    Thus, he then looked at the very end of the invitation.


    There was one line of a simple equation.


    F=GMm/r^2


    However, these mathematical symbols... he couldn’t understand them at all!


    What did this F represent, and what was this G about?


    Harrov, clueless about these mathematical symbols from another world, could only guess based on his research, and he had a premonition that what he was pursuing was within this line of a simple form!


    @@novelbin@@


    "Where is Lynn, where is he now?" Harrov suddenly remembered the sender of the letter and eagerly asked, for the other party must understand the meaning of this form.


    "Tea... Teacher, because it was veryte yesterday, the wizard named Lynn had already gone back... As for now, he is probably attending a seminar," Trisha stammered, not daring to mention that she had intentionally kept him out at the door.


    "I’ll go and bring him back right away!" Trisha hurriedly nned to go out and bring Lynn back.


    As for the previous disagreements, she couldn’t care less about them now.


    Trisha knew very well that she was just a third-ring wizard with ordinary talent, who had initially provided Harrov some inspiration with an academic paper, and that had earned his appreciation and the position as his apprentice.


    If this legendary wizard knew about such a big oversight of hers, her current position might very well be in jeopardy.


    "No need, it’s too slow, I’ll go myself," Harrov thought, and the messy research manuscripts in the room quickly organized themselves into his hand, then he flew straight out of the wide-open window.
