Hogwarts passer-by professor

Chapter 417 Returning to Modern Times
"Professor, are we going to the future?" Hermione looked shocked as she looked at the changing scenes in front of her.

"Didn't I just say that we can look at the rise of mankind in another way. To me, this is just a means!" A smile appeared on Aisen's face unconsciously.

"Those apes have changed so much!" Hermione couldn't help but murmured as she looked at the extinct apes and the surviving apes' descendants.

"Natural selection, survival of the fittest. This sentence is true!" Eisen nodded, and Hermione continued to observe the changes in the earth.

The descendants of the apes have become more and more successful in using tools.

Their hands became more dexterous with clubs and flints.A look at the ancient history of the whole earth will reveal that this is unique among all living things.

In this way, they can make more sophisticated tools.And more sophisticated tools made their minds and limbs develop in a more developed direction.

This is a virtuous cycle, and it is a process that is constantly accumulating and accelerating.

During this period, many disasters occurred on the earth. Many species disappeared and many species were born.But the descendants of the apes survived tenaciously.

Eventually, after the species evolves to a certain level, a qualitative change occurs!Then, humans were born!
Unlike all the beasts that lived on the earth in the past, humans are good at summarizing the past, gaining enough knowledge, and then starting to explore the future.

Humans began to learn to control nature, master fire, domesticate wild animals, and touch magic... Then, the stone tools that have been used for tens of thousands of years gave way to bronze and iron tools.

Immediately afterwards, hunting was replaced by livestock, tribal chiefs were replaced by villages, and villages gathered and became towns.Relying on stone carvings and bone armor, language is immortalized.

Human bodies are getting thinner and thinner, but their methods of using tools are becoming more and more terrifying.In this way, the bright light of human civilization blooms across the entire earth, and its rays of light will burst out of the earth sooner or later!

……

The hazy silver light around them dissipated, and the figures of Eisen and Hermione reappeared in the world!
"How do you feel?" Looking at Hermione still stunned, Eisen asked softly.

"It's so shocking! It's hard to imagine that human beings became the rulers of the earth step by step like this!" Hermione came back to her senses, with a complicated expression on her face.

"Yeah, I told the little wizards at Hogwarts before that in this world, there are two things that we should look up to for the rest of our lives: one is the bright starry sky above our heads, and the other is the noble moral law in people's hearts. "Aisen said with a gentle expression.

"I remember, professor, you said this was what a philosopher named Kant said." Hermione immediately remembered what Eisen said.

"Yes, I have always agreed with his point of view. But now, I think I can add one more thing, that is, the entire history of human civilization is the most shocking thing in the world!" Eisen said with emotion.

Hermione nodded and said nothing, just stood quietly, as if recalling the experience of the past few days.

After a long time, Hermione restrained her emotions and set her sights on Eisen: "Professor, let's go back!"

"Aren't you going to go for a walk in this day and age?" Eisen looked around sideways and gestured to Hermione to let her look around.

"No, I need to digest the experience of the past few days for a while!" Hermione looked at the smoke of fireworks in the distance, and then shook her head.

It could be seen from Hermione's expression that although her mind had calmed down, the experiences of the past few days had greatly touched her.

Thinking of this, Eisen understood what Hermione meant.

"Okay, let's go back now!" Eisen grabbed Hermione's arm. After saying that, with a thought, the two of them disappeared directly from this era.

……

The afternoon of August 1996, 8!
In a room in the Leaky Cauldron, the figures of Essen and Hermione suddenly appeared out of thin air.

"You're back, Professor!" Hermione couldn't help but smile when she saw the surrounding environment changing.

However, before Eisen could say anything, he noticed that the backlash of time quickly gathered on the two of them.

With a thought, Eisen transferred his blur to Hermione, drawing the power of time backlash to himself.Suddenly, the feeling of time passing appeared on him, but it did not have any impact on him at all.

Previously, Eisen had integrated the immortality properties into his body, especially after transforming into the mythical immortality properties, he had already gained great immunity to the backlash of time.

Nowadays, Eisen controls the power of the five elements, which itself represents the five elements of the entire universe. Naturally, it is easier to ignore the backlash brought by time.

"What's wrong, Professor?" Seeing that Eisen didn't speak, Hermione immediately asked.

"It's okay!" Eisen smiled and shook his head, "By the way, where are you going to go next?"

"Next, I have to prepare the sixth grade textbooks. There are still two weeks left in the new semester, so I have to review them in advance!" Hermione looked out the window and said slowly after thinking for a while.

"Sixth grade textbook, yes, you really need to prepare in advance!" Aisen said with a smile, "By the way, have you finished your holiday homework?"

"Of course! I finished it a few days ago!" Hermione said with a proud look on her face.

"Let's go, let's go to Lihen Bookstore!" Eisen stood up, and was about to walk outside, but stopped to look at Hermione, "By the way, are you hungry, do you want to eat something?"

"Uh, Professor, you forgot, the energy-draining runes you carved on my body, I no longer feel hungry!" Hermione said, looking at Eisen with a somewhat resentful look.

"Okay, I almost forgot!" Aisen smiled awkwardly.

"However, Professor, let's have some barbecue! Dinosaur meat is still delicious—" Hermione narrowed her eyes as she spoke, as if thinking of something, she couldn't help swallowing.

Smiling and nodding, Eisen brought out a copy of the prepared dinosaur barbecue from the food storage room in Futaba Paradise.

Place several plates on the table, then divide the dinosaur barbecue into several pieces and place them on it.Then he and Hermione sat aside and enjoyed it.

But seeing Hermione's stunned attitude after tasting it for a few mouthfuls, Eisen felt very strange: "What's wrong? Is there any problem?"

"No, it's nothing!" Hermione started eating as if she had just woken up from a dream, "I just feel that magic is a bit too unscientific!"

"Oh! Why do you suddenly feel this way?" After hearing Hermione's words, Eisen couldn't help laughing.

how to say?The extraordinary power of magic is indeed very unscientific.But there is no way, this world is like this!
"Although magic cannot create food, it can make the existing food larger and more abundant!" Hermione wiped her mouth, "Professor, tell me, if there was enough food, would any species be able to survive from ancient times? Come down?"

"Maybe!" Eisen raised his eyebrows, "The reason why species reproduce successfully is nothing more than a suitable environment and sufficient food. If there is enough food security, then the difficulty of survival of the entire species will be greatly reduced!"

"Actually, I think the impact of the environment may not be that big. I mean, unless it is a very extreme environment, for example, an uninhabited desert like the North and South Pole, or directly at the impact of an asteroid." Hermione thought and said .

"What you said makes sense. After all, the earth's environment is diverse. Even if it encounters some natural disasters, species will still try their best to find a suitable living environment!" Eisen said in agreement.

"Professor, do you think that if dinosaurs mastered the magic of making more food, they would become extinct?" Hermione picked up a piece of barbecue from the plate and stuffed it into her mouth.

"This - probably not!" Eisen thought for a while and said slowly, "Mastering the magic that can increase food means that they have no pressure to survive."

"Wouldn't the disaster caused by the asteroid hitting the earth also affect the dinosaurs?" Hermione looked at Eisen blankly.

"Maybe their lives will be affected a little at first." Eisen said lightly, "Didn't I say before that an asteroid hitting the earth will cause a significant cooling of the earth's surface.

However, if there is sufficient food, then they only need to survive the earth's temperature anomalies. "

"The professor means that with enough food, those dinosaurs will survive for hundreds of years until the earth's environment recovers?" Hermione nodded thoughtfully.

"Yes, the main reason for the extinction of the dinosaurs, as I said before, is a series of problems caused by the impact of the asteroid on the earth. For example, the temperature dropped rapidly, the plants that relied on photosynthesis died, the food chain was broken, etc.

But if the dinosaurs themselves had magic and could increase the food they originally relied on, then they would only face the problem of falling temperatures. "

"Won't dinosaurs freeze to death?" Hermione cleaned up the food residue on the plate and continued to ask.

"The impact of the asteroid on the earth has caused the global temperature to drop, and the temperature has dropped by 10°C to 20°C at most. It is impossible to say that it has dropped to the extremely low temperature of the North and South Poles all at once.

Therefore, I think the dinosaurs could probably handle it! "Seeing that Hermione had finished eating, Eisen stretched out his hand and put the plate away.

"In other words, if you master the magic that can increase food, dinosaurs will continue to survive and multiply on the earth?" Hermione stood up and stretched her body.

"I think that if any race can master the magic of increasing food, it will be able to reproduce and survive smoothly unless it encounters a very extreme natural disaster!" Eisen shrugged his shoulders.

"Then, is it a very lucky thing for human civilization that some people in the human race have mastered magic?" Hermione sat down next to Eisen.

"Well, this problem is quite complicated!" Eisen said, once again thinking of the wizards in this world who had to legislate to hide their behavior due to the persecution of Muggles.

"Is it because things in the wizarding world are hidden from Muggles?" Hermione seemed to know the key.

"It doesn't matter, the times are always developing!" Eisen said indifferently, "Now, wizards have been hiding themselves. But, who said that after decades or hundreds of years, wizards still need to hide?"

"Then Professor, when will wizards no longer have to hide their identities?" Hermione looked curious.

"As far as the current situation is concerned, I think there are two situations where the wizard will no longer need to keep it secret!" Eisen said with a smile.

"Two situations?" Hermione was surprised.

"In one situation, human civilization has encountered a major existential crisis!" Eisen said seriously.

"Like a dinosaur hit by an asteroid?" Hermione said thoughtfully.

"Maybe. Once the human race encounters a life-and-death crisis, the most important thing is for the wizards to appear in the Muggle world." Eisen nodded.

"What about the other scenario?" Hermione asked.

"In another situation, it's about the development of Muggle technology." Eisen laughed.

"Is technology developing?" Hermione seemed to understand something.

"Yes, in this era, magic is to a large extent more convenient and more magical than science and technology.

But one day, when Muggle technology can do what magic can do, do you think wizards still need to hide their identities? "

"What the professor said makes sense!" Hermione had a look of realization on her face.

"But we don't need to think too much about this. We can just watch quietly and watch how the wizarding world will develop in the future!" Eisen said gently.

"That's right!" Hermione's face straightened, and then she laughed happily, "Let's go, Professor! Let's go to Diagon Alley for a walk!"

"Okay, let's go shopping in Diagon Alley and buy some sixth grade textbooks at Flourish and Blotts Bookstore!" Eisen stood up with a smile and walked outside with Hermione.

……

After entering Diagon Alley from the small patio behind the Leaky Cauldron, the sky was already getting dark.

However, there were all kinds of magic lights flashing outside the entire street, so it didn't look gloomy at all.

The cobbled streets stretched into the distance. Wizards walked into the shops on the street, and wizards walked out of the shops.

The busy scene made Eisen and Hermione feel more peaceful.

After walking for a few minutes, Essen and Hermione entered Flourish and Blotts Bookstore directly.

"Professor, let me go take a look!" After entering the bookstore, Hermione told Eisen and walked inside.

Aisen nodded and looked around in the bookstore.

The layout inside Flourish and Blotts Bookstore has remained unchanged for thousands of years, and it is not much different from the display state that Eisen saw when he came in before.

The bookshelves are full of books. Some books are as big as paving stones with exquisite covers, while others are only the size of a palm with strange runes engraved on the covers.

Some of the books were clearly newly printed, but others were clearly second-hand.

Seeing these books on the bookshelves, Aisen's heart moved, but he thought of the five elements of authority that he had already controlled.

Immediately as the thought occurred, a wave that no one could detect gently passed through the entire bookshelf.

After perceiving every book in the entire bookstore, Eisen took advantage of the convenience of the Five Elements Rule to imprint the contents of all the books and put them into the memory palace of the dream world.

After doing this, Aisen couldn't help but reveal a smile on his face.

This move was just an attempt, but Eisen didn't expect it to be a success.

how to say?Before that, if Eisen wanted to move the contents of the book into the dream world, he had to turn the pages of the book himself to scan the contents of each page with his eyes.

This was always the case whether it was in Hogwarts School or Zhengyi School.

He also thought about replicating all the books in the library directly into the dream world.However, although the dream world is completely under his control, he cannot interfere with reality.

Originally, Eisen thought that after accumulating more power of faith in the future, he might be able to make some changes in the dream world, so as to break the boundary between illusion and reality, and allow the dream world to interfere with reality.

That way, he could use the dream world to scan the Hogwarts library and move all the contents directly into the memory palace.

But what I didn't expect was that Aisen directly controlled the power of the five elements and became a real "god".

This time, on a whim, Eisen tried it.

Then I discovered that I could indeed use the power of the Five Elements to directly copy the contents of all the books in Flourishes and Blotts Bookstore into the Memory Palace.

In this way, it is also an unexpected gain.

"Professor, let's go!" Hermione came over holding a stack of books.

"Have you bought the book?" Aisen said with a smile on his face.

"That's right! Professor, do you want to buy a book?" Hermione looked at Eisen with empty hands and asked.

"No, let's go!" Aisen smiled and shook his head.

After leaving Flourishes and Blotts Bookstore, Hermione took the time to put the books into the Twinleaf Paradise space.

"Where else are you going next?" Looking at Hermione's suddenly excited expression, Eisen asked with interest.

"Emmm... how about we go to Weasley's Wizarding Wheezes? They should still be in the shop, right?" Hermione rolled her eyes and then suggested.

"Go to Fred and George! They have graduated this year, haven't they?" A smile appeared on Eisen's face.

"Yes, they have completed seventh grade at Hogwarts!" Hermione nodded.

"Okay, you can go to their place for a visit!" Eisen said gently, and then walked with Hermione in the direction of Weasley's Wizard Wheezes.

A few minutes later, the two came to a store.

Looking through the window of this shop, you can clearly see the firelight shining, displaying wantonly like fireworks to attract attention.

Many wizards, especially young wizards, were attracted by this place and walked into the shop.

No way, for children, the flashing, screaming, rotating and other products displayed in the window are a bit too exciting.

"Hey, Professor Eisen, and Hermione, welcome to Weasley's Wizarding Wheezes. Do you want any prank products?" Fred, who had just entered the store, wearing a red robe and a smile on his face, shouted loudly shouted.

"The business here is not bad!" Looking at the slightly crowded crowd in the store, Aisen shook his head helplessly.
