Harry Potter and the Rebirth

Approaching the door, Harry did not feel as relaxed as he had when entering a professor's classroom. His heart was pounding nervously and he lowered his head to check his clothes to see if they were neat and tidy.

Harry raised his arm and knocked lightly on the door with his knuckles. His slender and powerful fingers hit the wooden door, making a crisp sound of "dong dong dong".

"Come in." A male voice came from the door. Harry turned his head and looked at Gryffindor, who nodded to him, encouraging him to go in.

Harry took a deep breath, pressed the doorknob and entered the classroom. The bright light in the classroom was so bright that Harry couldn't help but shield his eyes with his hands.

"Huh?" Ron, who was still in the classroom, raised his head and struggled out of the densely packed words in the book. He glanced at Hermione who was studying hard, and then glanced at the front of the classroom. There was no one there.

The whole classroom was quiet. The midday sun shone on the desks, and the reflected light shone on the ceiling of the classroom. The chirping of birds came from the window. Ron turned his head in confusion. Why did he always feel that there was someone in the classroom?

"Now that you're here, sit down." The man adjusted the bow tie around his neck and tied his loose hair at the back of his head with the small rubber band in his hand.

She tied a curly, slightly playful ponytail at the back of her head.

"Okay, teacher." Harry sat in the first row obediently and opened the book that had been placed on the desk a long time ago. It was a book about the use of runes. Harry was immediately embarrassed. He really didn't know how to read a book like this...

The man on the podium waved his hand, and a huge curtain fell down. A beam of light shone from behind and above Harry, shining on the curtain.

"I told you about some of my experiences last time." The elegant and slightly artistic teacher began.

"Yes." Harry thought of the shock he felt when he first heard about this experience. If it wasn't for chance, he might not be able to meet such a big shot even as the savior. How could he trace back a dead soul? Even Dumbledore couldn't do it.

"Before I died, I was born in England, went to Eton School, and graduated from Cambridge University. I was an economics expert and had published some theories that made a slight contribution to the economic development of the world as a whole." The man said modestly.

Harry, however, was already familiar with this man.

When he was a child, he didn't know how great Eton School, which was praised by his Aunt Petunia, was. It was not until he grew up and traveled around that he realized that the British aristocracy, members of the royal family, and children of business tycoons were almost all the elites in Britain.

As for those theories, Harry had been cramming Muggle history for some time, and he knew them very well. Decades ago, this man's theories saved the United States from disaster, and it has also become the guiding ideology for many countries to carry out macro-economic construction.

Such a great man is now his teacher. However, teaching him economics is okay. Harry looked at the book in his hand. Why does it feel like it is not suitable for his major?

The man smiled, as if he saw the doubt in Harry's heart. "After I died, Mr. Gryffindor found me and brought me to this sacred land." The man looked around with a little awe. "I never knew there were such a group of people in the world."

"I put 100% of my energy into learning here, madly absorbing knowledge from another world. I thought I had understood the whole picture of the world, but I didn't expect that I was still a frog in the well."

The man looked at Harry seriously, "I already understand the situation of the whole world. I don't want us to be food in someone else's pot."

Harry felt a heavy burden on his shoulders. He nodded seriously, his eyes full of determination and perseverance.

The man glanced at it with satisfaction, "Because my brain works well, so..." He stretched out his tone and continued with a little pride, "I have basically mastered the existing magic in the wizarding world and most of the runes."

He paused and said with a sigh, "This is really interesting. It is completely different from the economic theory that I am good at."

Harry felt a little ashamed. Look at him, the genius is indeed a genius.

"Now, let's start the class."

The man ended the small talk and began to instill his understanding of runes in Harry. "The essence of words is expression. It can be called runes, English, or Chinese. There is nothing special about it. It is just a convention that allows people to understand each other, just like painting, music, and film and television."

Harry's face was full of confusion. How could these two things be connected together?

The man explained, "All four have one thing in common, which is to express feelings and understand each other. You can understand what the other person is saying through words, mobilize your emotions through music and movies, and understand the author's emotions or express your own emotions through paintings. It's just that the carriers are different, just like finance."

The man smiled gently, and he produced a gold coin out of thin air and held it in his hand.

"Why is gold coin wealth? Is it just because it is a precious metal, easy to carry, divide and store? Not just that, but in the long-term historical development process, people have agreed to use gold coins as their own form of value preservation. This is a kind of default. Gold coins have achieved something that everyone recognizes, so they have become wealth."

"So the key is understanding, the understanding of words, the understanding of music, the understanding of paintings, and the understanding of wealth recognition are all the same."

Harry opened his mouth wide, his eyes full of surprise, as if he saw a new door slowly opening to him.

"And now, the understanding between people has been replaced by people's understanding of magic and nature. People's understanding of magic has condensed into mysterious patterns, and then they can communicate with magic, thereby controlling and using magic."

Harry shuddered at this, straightened his back, and stared into the man's eyes intently.

"Professor, I understand that people understand each other, but why can people understand magic? What is there to understand about magic?" Harry asked.

"Then how do you normally cast spells?" the man asked.

Harry frowned, thinking carefully about the process of casting the spell, which was to feel the energy in his body, and then recite the spell and it would come into being.

Harry took a deep breath. Something as ordinary as this was not something he would dig into the details of.

"Your body can store, absorb and transform magic. This is the understanding of magic that is engraved in your genes as a wizard. Muggles cannot bear magic because their bodies cannot understand it."

"And a wand not only enables magic to be better exerted, it also builds a bridge of communication and expression between magic and the form of the spell you want to cast." The man raised his wand on the podium.

Hold it up in front of you.

Harry seemed to have some feeling. In the past period of time, he had used his own eyes to see the flow of magic in Hogwarts Castle. Sometimes when he was obsessed, he felt that it was a kind of art. One day, when he went to the dining table in the kitchen and tried to memorize the magic patterns carved on it, he actually had the illusion of looking at an abstract painting.

Harry seemed to understand somewhat what the professor was talking about.
