Hogwarts passer-by professor

Chapter 277 Preliminary Production
"Professor Eisen, I heard that more than half of the warriors who participated in the Triwizard Tournament died. Is it true?" When Eisen was sitting with the trio, Seamus of Gryffindor He suddenly lowered his voice and asked.

After hearing such horrifying content, the trio looked at each other and then looked at Aisen, waiting for his answer.

"Who did you listen to?" Eisen raised his eyebrows and said in a rather calm tone.

"I overheard the conversation between Crabbe and Goyle of Slytherin!" Seamus glanced at the Slytherin table and whispered.

"Are you crazy, Seamus!" Ron couldn't help but muttered, "Do you believe what the Slytherins say?"

"But people did die in previous Triwizard Tournaments, didn't they?" Harry glanced at Ron, "Dumbledore said that the reason why previous Triwizard Tournaments were canceled was because they were too dangerous! "

"The previous Triwizard Tournament was indeed very dangerous." Eisen said slowly, "But don't worry, the three schools and the Ministry of Magic are fully prepared for the restart of the Triwizard Tournament this time. Moreover, I I will participate as a safety officer and will not put the warrior’s life in danger!”

After hearing what Eisen said, Harry and others stopped saying anything.

After eating, the little wizards left in pairs and headed toward the classrooms on each floor.

However, what surprised Eisen was that Harry, Ron and others were lingering, as if they were reluctant to leave the auditorium.Even Hermione showed a bit of confusion on her face.

"What's wrong? Don't you want to go to class?" Aisen asked in surprise.

"It's Hagrid's Care of Magical Creatures class later." Harry and Ron's faces fell, and Hermione next to them said with pursed lips.

"Is there any problem?" Eisen looked at Hermione in surprise.

"The squids raised by Hagrid have grown up, and he wants us to tie them with ropes and go for a walk!" Seeing Eisen's surprised expression, Hermione's delicate white face turned red.

"Yes, Professor Eisen, you didn't see those snails. They have grown to more than three feet long and are very strong!" Ron said, with a look of extreme resistance on his face.

"They are so energetic. After their tails explode, they can drag us to the ground." Harry said with a look of shock on his face.

"Uh--, I think Hagrid will help you with protective measures, right!" After pondering for a while, Aisen said slowly, his tone was quite calm.

"He asked us to wear dragon leather gloves, but I don't like those snails!" Ron spread his hands, showing a helpless look.

"Maybe you can train your reflexes!" Eisen said thoughtfully, "I mean, when the snail's tail explodes, you can cast a barrier spell to resist the aftermath of the explosion. This is for you , it shouldn’t be too difficult!”

"This method is great!" Harry and Ron looked at each other, and they could see the surprise in each other's eyes.They never seemed to think about it.

Hermione's eyes lit up and she smiled at this time.

"Professor Eisen, goodbye!" Then, the trio waved to Eisen, turned and left.

……

in the office.

Eisen sat behind his desk, quietly looking at a "brick" placed on the table, thinking quietly about something.

After having dinner earlier, Eisen left Hogwarts and went to the Muggle world when he was free.

In fact, it's not a big deal, it's just the previous plan to refine the "Book of Essen".Since you want to refine the "Book of Essen", you naturally have to prepare some materials.

In fact, for Eisen, after possessing magical power, it should not matter what materials are used.Anyway, they can be made indestructible through magical means.

But considering the conductivity of magic power, Eisen still felt that he needed to choose.

However, I don’t know if it’s an illusion, but Eisen always feels that the magic transmission in this world is a very confusing thing.

Let me give you an example.

Previously, Eisen thought that the material with the best magic conductivity in the world was wood.

There is no way, because wizards in the wizarding world-leaving aside other places, as far as Eisen knows, the wands used by all people are made of wood.

Whether it is holly wood, grapevine wood or yew wood, there is nothing special about it.At most, the core is added to form a magic wand.

This made Eisen think that the metal materials in this world have very poor conductivity to magic power.

However, after trying it himself, Eisen discovered that this was not actually the case.The conductivity of metal to magic power is actually quite excellent.

Some pure gold, pure silver and other metals have very good magic conductivity, and even some alloys have very good magic conductivity.

In this case, why don’t wands in the wizarding world use metal?

Aisen pondered, and time gradually passed.

After a while, he seemed to think of something, and a look of sudden realization appeared on his face.

Only then did he realize that he was actually over the top.Because the wand-making craftsmanship in the wizarding world can be traced back to a long time ago.Just like Ollivander's wandmaker, he started making wands as early as 382 BC.

At that time, regardless of craftsmanship, wood was definitely the cheapest material suitable for making wands.Therefore, for thousands of years, the wizarding world has been using wooden wands, which may have a lot to do with this.

As for gold and silver, they are both money for wizards, so of course they cannot be used to make wands.

After thinking about this, Aisen shook his head slightly, picked up the "tiles" in front of him and observed them carefully.

This is a piece of "titanium alloy" that Eisen purchased in the Muggle world. After some selection and trial, Eisen thought it would be quite suitable to use it as the basic material of "The Book of Eisen".

After taking a deep breath, Aisen stretched out his fingers and rubbed it.

A trace of light emerged from the fingers, and after crossing the bricks, the bricks seemed to change.Like running water, ripples appeared on the surface of the bricks and spread rapidly.

Visible to the naked eye, the titanium alloy brick in front of Eisen's eyes is rapidly growing in size and thinning at the same time.Then, Eisen's mind turned, and the edges of the titanium alloy tile became softer.

At this moment, the original titanium alloy brick in Eisen's hand has turned into a titanium alloy book-style model that is 21 cm long, 15 cm wide, and 2 cm thick.

Looking at the basically formed model in his hand, Eisen's face spread with a smile, but his movements did not stop there.The magic power in his body is running, Aisen's thoughts are turning, and the book model in his hand is changing rapidly.

It was as if invisible blades were streaking across the model quickly. In a moment, the book model in Eisen's hand had turned into a real titanium alloy book.

However, although it has been made into a book style, it is made of alloy and it is extremely inconvenient to turn the pages.Therefore, Eisen had to use magic to transform it.

Of course, in addition to using the transformation spell to add some flexible properties, Eisen also added a large number of protective spells such as firming spells, waterproof spells, and fire-proof spells to it.

Time passed slowly, and when Aisen stopped all movements, a satisfied smile appeared on his face.

I saw that the appearance of the book in Eisen's hand was completely different from before.

From the surface, this book is no longer made of alloy.Because it has been transformed by magic and turned into a real book, at least on the surface.

The cover looks silvery white, but it has no metallic texture at all. It has the four characters "Book of Eisen" written on it.In addition, Eisen stamped the "∞" shape on the front and back of the cover.

After opening it, you will find that the color of the pages inside does not look like alloy material, and they look as inconspicuous as ordinary paper.

Of course, this "Book of Eisen" is still blank.Whether it needs to be filled with content, or what kind of content needs to be filled in, Eisen needs to consider it himself in the future.

However, for Eisen, the book used as the carrier of the contract has been refined.So, the next thing to do is to study the Goblet of Fire and the contract that connects it and then dismantle it.

Only in this way can he conclude a contract with the "Book of Essen".

However, the Triwizard Tournament will last for one school year.

Therefore, Aisen is not in a hurry with his research, just take his time.
