The Villain Only Wants To Live a Buddhist Life
Chapter 258:

An equation is a formula that contains a variable X.

It is not some advanced knowledge, but a simple calculation tool.

By solving equations, one can avoid the difficulty of reverse thinking, and directly list the formula containing the variables to be solved.

For the application of basic equations, the most popular was to solve the problem of chickens and rabbits in the same cage.

Dark just quickly explained the knowledge he knew, and Professor Lily was enlightened instantly!

She quickly said: "A similar method was mentioned in Canon of Goniello, but it hasn't been integrated into a complete system. Using this method can really simplify the calculation. Although I don't need it...emmm, can you tell me a bit more about it?"

Dark asked curiously, "What is the Canon of Goniello?"

Professor Lily: "An ancient religion that worships geometry, but it has probably been reduced to ashes now."

The corner of Dark's mouth twitched: "So a religion of mathematics?"

Then he followed Professor Lily's request and explained. "Equations come in many forms. What I just talked about is a linear equation in one variable. In addition, there are also linear equations in two variables, quadratic equations in one variable, etc., and equations can be formed to solve multiple variables..."

When it comes to quadratic equations in one variable, we have to talk about exponentiation, which is "power".

With the definition of "power", it is necessary to mention "base number", "exponent", "square root"...

Dark explained in detail, and Professor Lily listened carefully. Soon a basic model of mathematical operations was gradually formed in the exchanges between the two.

The more Dark explained, the more shocked Professor Lily was.

Since the introduction of the concept of "power", she has discovered some extremely complicated calculations. After using "power", it seemed that a straight road was suddenly folded, making the beginning point and the end point suddenly become very close!

Obviously, this was a concept far beyond addition, subtraction, multiplication and division!

Professor Lily originally just wanted to get an algorithm like "Column Calculation Method" from Dark, but she didn't expect to get something even more amazing.

After thinking carefully, she suddenly took out a pen and paper from the drawer, wrote out various complex problems out of thin air, then introduced the concept of "power", and then solved it with equations. Her thoughts became very clear and the calculation was unbelievably smooth.

"Whew!" She raised her head with a flushed face, but found that the person on the sofa was already gone.

...

In order not to go to the History of Magic class in the afternoon hungry, Dark chose to stop explaining further and slip away.

Seeing that Professor Lily could draw inferences from other facts just by understanding some definitions, Dark was actually a little envious. Maybe this was what a real genius was like!

When he came to the cafeteria, he ordered a steak and mince pie, ate it quickly in the empty cafeteria, and then hurried to the classroom of History of Magic.

By the time he entered through the back door, the classroom was already full of people.

White and Robert, who were sitting at the back door as usual, looked over curiously, surprised that he came so late.

But White already had some hostility towards Dark in his heart, and he had given up on the plan to increase his favorability, so he didn't talk to him.

Robert didn't have that much scruple, and said on the spot, "Hey, Dark, where have you been? Why are you late today?"

Dark turned his head and said with a smile, "I went to discuss some issues with Professor Lily."

Robert; "Oh."

White couldn't help but ask, "Is it related to the morning class?"

"Yeah." Dark nodded, then moved on, and soon returned to his seat.

Before long, the bell for class rang.

The professor of History of Magic, Ryan Hex, walked in with a cane.

He was still wearing a tattered prosthetic limb, and he limped when he walked, but the expression on his face and his temperament were very different from when he just came to the academy.

Just one week of academy life made him lose his strong temperament of old age, and his face also recovered a little bit of vigor.

But what attracted the students the most was his almost bald head - it grew hair again!

"Professor!" A Knight House student in the front row couldn't help raising his hand and said, "Your hair?!"

Professor Ryan Hex raised his intact hand and flicked his dark brown bangs back, slightly proud: "Theodore, you need to relearn your manners."

"Okay, Professor." Theodore mumbled and sat down.

Only then did Professor Hex say, "I'm just helping Sister Kaleid in an experiment. Oh, she called that thing Hair Restorer!"

"Oh, so a guinea pig..."

Dark in the last row blinked, thinking that Professor Hex shouldn't be happy too soon.

If Hair Restorer could be developed so easily, there wouldn't be so many bald great nobles.

But with thick brown hair, Professor Hex really looked like an old handsome guy after shaving off his beard.

After Professor Hex took the podium, he continued the content of the previous lecture and continued to tell the unfinished war story.

It was a pity that when the Golden Generation headed by the Brave One and others was vigorously active on the battlefield, Professor Hex had already retired due to injury. Although he knew the battles that he did not personally experience, he lacked some details.

Therefore, he talked more about the early battles. Humans at that time had no advantage, and every victory had to pay a heavy price, but the significance of each victory was unprecedented.

Professor Hex's previous two lectures were about the battle that ultimately won, but in this class, he seemed to have changed his mind.

Fifteen minutes after class started, Professor Hex said: "In war sometimes there is victory and sometimes loss. We gain experience from victory and learn from failure. The so-called history of war is also a history of sacrifice. I will always remember the sacrifice of comrades in arms, and never will I forgive those who betrayed us in the war!"

As if he had thought of something, he quickly clenched his fists to conceal the hideous expression appearing on the corners of his mouth. After calming down, he continued: "The battle of the Ghost Ox Tribe was the sad chapter in the history of modern warfare, the tragic battle that almost broke the Hundred Races Alliance!"

The students in the audience couldn't help but pay attention.

Professor Hex always gave lectures with strong personal emotions, but it was more engaging this way.

Even Dark couldn't help listening.

The battle of the Ghost Ox Tribe was a battle that took place in the early days of the Hundred Races Alliance Treaty.

The Ghost Ox clan of the Beastmen clan called the Alliance for help at that time.

After the urgent discussion, the alliance immediately regarded it as a key battle that symbolized the alliance, and sent an alliance army composed of the four races of Beastmen, elves, dwarves and humans to Ghost Ox to rescue.
