Good fellow, I'm Galileo......

Just as Lynn was silently complaining in his heart, a voice sounded behind him.

"How do you feel, are you satisfied? Professor Lynn? ”

The man who spoke was Tik, an alchemist from the City of Wizards smuffling his beard rather smugly.

After Lynn ran away last night under the pretext of drunkenness, the professors discussed how to record this morning's shocking experiment in the form of sculptures.

This is one of the highest honors of the entire college!

It means that every student who joins the Iyeta Academy in the future will be able to pay tribute to each other's deeds the moment they walk through the gate of the academy.

He also made some small suggestions for the external expression of this sculpture, coupled with the magic of several professors and the hard work of the elves day and night, it was completed in just half a day.

"It seems... Kindness... It's shocking......" Lynn said against his will, in fact, he felt that the artistic standard of this sculpture was really average.

Tik himself was very satisfied with the work, and did not hear the perfunctory words of the other party at all, but on the way to the Mathematics Olympiad classroom, he explained to Lynn how to express the inner thoughts of a wizard through sculpture.

Lynn always maintained a polite smile on her face until she stepped into the classroom.

After the class division, the number of people in the entire elite class was much smaller, and only forty-six people remained.

No, I'm afraid it's going to be forty-seven from today.

Because there's one more Lydia!

At this moment, the halfling girl was sitting at the front of the whole classroom, due to her short stature, the table and chair were characteristic, one size smaller than the others, it looked very abrupt, and Lynn focused on her at first sight after entering the door.

Facing Lynn's gaze, Lydia did not tremble like the other students, but held a parchment scroll in anticipation, and said eagerly. "Professor, can we start classes now?"

Alok, Peirce, and the others looked at Lydia with a little pity and nostalgia in their eyes, and vaguely remembered that they were so excited when they took the Olympiad class on the first day.

"Since everyone is so impatient, let's start classes now!" Lynn turned to look at the gray-haired witch and spoke.

"Jonny, put everyone's homework away......"

"I gave you a whole day, so you must have calculated the area of the Lookout, right?" Lynn said with a smile.

As soon as these words came out, there was a wail in the classroom.

As members of the elite class of the Olympiad mathematics, each of them is not bad at arithmetic, but the structure of the Sky Lookout is very complicated, and the best airship airbag is still oval.

Even though Lynn has taught the corresponding formula and given some of the data, it is still extremely difficult to calculate it accurately.

But no matter how unwilling they were, they could only hand over the manuscript of the calculation, and Lydia was no exception.

In fact, during the most of the month of making the airship, every time Lynn took the time to explain the drawings to her, she would explain a lot of geometric formulas and theorems by the way, so her learning progress was actually not lower than that of these elite class students.

Lynn took the stack of parchment rolls that Jonny had brought up, and when she saw the first one, she couldn't help frowning, and spoke. "Debra, how come there is only the area of the airbag and the cockpit, and the rear wing?"

"But you didn't give me any data on the tail of the airship...... "The red-haired witch said weakly, standing up.

"But it can be calculated, can't it?" Lynn looked at the wizards present and explained.

"The shape of the tail can be split into an equilateral right triangle plus a square, I gave you an equal scale plan, as long as you pay attention, you can find that a hypotenuse of the cockpit and the hypotenuse of the airship tail is parallel, the length is the same, since there is hypotenuse data, then the use of the Pythagorean theorem can easily calculate other data......"

It's not easy at all...... The red-haired witch wept with a sad face.

Lynn was ruthless and said directly. "When I go back, copy the formula fifty times! Also, before the end of class, give me a new set of data! ”

The students in the audience couldn't help but shrink their necks, and they couldn't calculate the area of the tail wing.

"What is this Pythagorean theorem?" Tik turned his head to look at Alok on the side, and asked in confusion.

"It's a law of operation discovered by the professor, a right triangle on a plane, adding the squares of the two right-angled sides, will be equal to the square of the hypotenuse lengths......" Elok looked at his notebook several times to make sure he was not wrong, and his expression was vaguely excited.

Having participated in yesterday's award ceremony, he naturally knew that in front of him was a three-ring wizard and alchemy master!

Such a big man is actually asking himself questions!

Elok feels that this is probably the most glorious moment of his life!

"What is the square?" Tik then asked, saying that these terms were foreign to him.

"A square is the same two numbers multiplied by the same ......" Elok was so convinced that he didn't even look at the formula in his notebook, and then introduced the alchemist to the area formula for circles and polygons.

Tik's face showed a look of understanding, he had noticed a similar pattern when he was learning to draw circle patterns, but he didn't summarize the laws of each shape like Lynn, and formed an independent discipline.

Some of the alchemists in the Wizarding City like to ponder these things, and I heard that some people have even pushed pi to the ninth decimal place, which is simply more accurate than ever......

Alok glanced at Lynn on the stage, and estimated that he hadn't talked about his homework so quickly, and a bold idea could not help but pop up in his mind, and he looked at Tik and said with a worried expression.

"Mr. Tik, some time ago, Professor Lynn invented an interesting game, I wonder if you are interested?"

"What game?" Tik was somewhat curious.

Alok immediately came to his senses, picked up a quill, and randomly drew a three-by-six square on the parchment, and after thinking about it, crossed out the last square, and then explained the rules of the game.

"Does the amount of the next slot have to be doubled from the previous one, starting with a copper coin?" Tik repeats it, then wonders why Elok crossed out a square.

"Yes, as long as you can fill all the slots, then these ten gold coins are yours!" Elok took out all his savings and then continued. "But any coins you put down are mine!"

The difference between one copper coin and ten gold coins is a full 100,000 times......

Tik became more and more interested in the game, silently calculated in his mind, and then picked up a pen and filled in the squares.

As he filled in the last number, Tik was shocked and said with interest.

"Interesting, really funny!"

The seventeenth square is sixty-five thousand five hundred and thirty-six, so all the values add up to ......

"That's a total of 131,071 copper coins!" Alok hurriedly responded.

Tik took more than ten seconds to simply add it, and sure enough, it was exactly the same.

He knew from the beginning that he would lose, after all, it was impossible for the wizard apprentice in front of him to give him money for nothing, but he didn't expect that the addition of the small seventeen squares would actually increase the starting value by 130,000 times.

In this way, the other party deliberately crossed out a box, is it worried that the amount is too large and he will regret it?

Tik couldn't help but laugh, and since he didn't bring silver and copper coins, he directly took out four magic gold coins and put them on the table, he had always been willing to gamble and lose!

"Three gold coins are enough!" Elok didn't dare to ask for more, so he hurriedly pushed one back.

The alchemist in front of him was not the first person to be tricked by him, after being deflated by Professor Lynn before, he went home and immediately asked his father Albert to play this checkered game.

In the end, he theoretically won all the family's possessions, and Albert owed him tens of thousands of gold coins...... But as a result, he didn't get a penny, and he was beaten severely!

At this point, he understood a truth, excessive greed will be beaten......

Luckily, this master alchemist is a man of his word!

Elome accepted the three gold coins, but the next second he heard a familiar voice on the stage.

"Ellock, since you know all about the Olympiad formula, why don't you come to the stage and tell everyone!"

The joyful expression on the face of the fifteen or sixteen-year-old boy suddenly froze, and he couldn't stop shivering, and stood up with a slight trembling.

Lynn looked at him very "kindly".

Good boy, use the knowledge I gave you to trick others, you really have a set!

Under the gloating gaze of the students, Elok had no choice but to walk to the podium, pick up a parchment, and use his shallow knowledge of the Olympiad to stumble and tell it......

Elok had never felt that time was so long in his life, and he had forgotten everything in his mind under the nervousness, and there were bursts of laughter from time to time in the audience, and finally he was expelled after only ten minutes on the stage.

Considering Tik and Lydia's learning progress, Lynn revisited the geometric formulas she had previously taught in the rest of the lesson.

At the end of the lesson, Tik also gave him a return gift, a book that was four fingers thick - "Runes and Alchemy".

Although there are some basic alchemy books in the Iyeta Academy, they cannot compare to a gift from an alchemy master.

Lynn flipped through a few pages, and in addition to the analysis of some basic alchemy runes, the book had notes written at the bottom of each page.

Such a number of annotations could never have been improvised, but should have been a "textbook" used to teach a core apprentice.

Even this is a very precious gift, which means that when learning alchemy, you can avoid many detours.

Lynn casually said a few polite words, and then put away the alchemy book.

Tik, who had just finished listening to an Olympiad math lesson, had all kinds of questions in his mind that needed to be answered by Lynn, but after glancing at the halfling girl who had been wandering around since the end of class, he said goodbye and left very interestingly.

"Professor Lynn!" Lydia immediately came up, put her bulging money bag on the podium, stuck her waist, and said proudly.

"Yesterday, we sold eight hundred and thirty-seven tickets, a total of eighty-three magic gold coins and seventy silver coins, all here......"

The halfling girl chattered endlessly about the pomp and circumstance in the square yesterday afternoon, and the procession of the airships all the way to the dock of the harbor, and everyone couldn't wait to fly to the sky to have a look......

In just one day, so many tickets were sold, and Lynn was also a little surprised, it seemed that the charm of flying was even greater than he imagined.

"By the way, there is also this ledger, which Uncle Darren asked me to hand over to you!" Lydia took out a booklet that she had with her and slipped it into Lynn's hand, which recorded a list of all the people who had purchased tickets, and even made it clear which batch of airships were on.

Lynn asked Zhi Brain to write down all the data, and then took out the eight gold and thirty-seven silver that belonged to the halfling in the money bag, and returned it to Lydia along with the ledger.

"When you go back, tell Darren that you don't have to send this thing every day, just show me it every once in a while."

The halfling girl's expression became a little confused, because Lynn's reaction was not the same as what Darren and the others had predicted, such a huge amount, they thought that the other party would definitely ask for an inspection once a day.

Lynn didn't explain, he deliberately loosened the control of money, just to see if these halflings would make some small moves in secret.

An airship is just the beginning, and there are many opportunities to earn gold coins in the future, such as the wizarding land, which still uses very backward papyrus and parchment scrolls to record words, and he can make a lot of money by selling paper.

It's just that he can't do these things himself, and he definitely needs to hire some trustworthy people.

It depends on whether these halflings can keep their greed.

The two were chatting, and a rush of footsteps outside the door suddenly came, and then the door of the classroom was slammed, Lynn turned his head to look over, and saw no one at first glance, until he looked down and realized that it was Darren who had broken in.

I haven't seen it for a day, this bearded halfling has become much haggard than before, and he has entered the door and looked around, and when he saw Lynn, he suddenly seemed to see a savior, and said in a panic.

"Oh no, Professor Lynn, Ralph...... Ralph is dead! ”

Ralph? Who's that?

Lynn paused, and before he could think clearly, he was dragged away by an eager Darren by the sleeve.
