370 Chapter 369, Yuval's purpose

In the restricted section of the Hogwarts library, Tang Yan was the only person reading alone.

She looked at the full bookshelf and couldn't help sighing.

It is indeed Hogwarts with a history of thousands of years!
The collection of books in the restricted area alone is more than the magic collection of the Foley family.

No wonder the old pure-blood families all sent their children to Hogwarts to study, as expected, the school had stronger teachers.

Under Mrs. Pingsi's gaze, Tang Yan walked to the first row of bookshelves, squatted down, and started reading from the first book in the lower left corner.

Due to his strong mental power, Tang Yan reads books very fast, as if flipping through the pages.

Finished one soon.

She put the finished book back in its original place, picked up the second book in order, and flipped through the pages again.

She wanted to find books related to the Foley family, or books related to magic such as seizing houses.

She wondered if Yuval really had ulterior motives?

There are several kinds of spells related to seizing the house in the main god system, but there is no definite information to prove that the current magic world also has these spells.

So Tang Yan wanted to find reliable evidence to prove what he was thinking.

One book after another was flipped through.

It didn't take long for Tang Yan to read an entire bookshelf.

Mrs. Pingsi on the side frowned deeply, staring at Tang Yan without blinking.

Just when Tang Yan was about to flip through the books on the next shelf, Mrs. Pingsi finally couldn't help it.

She stepped forward, barely maintaining a smile.

"Professor Foley, what book are you looking for? I'd be more than happy to help."

Tang Yan did not explain to Mrs. Pingsi that he was reading a book, and felt that it was great to have Mrs. Pingsi, the librarian, to help him.

"Thank you. I need to find books related to the Welfare family. Do you know where they are?"

Seeing that Tang Yan was easy to talk to, Mrs. Pingsi breathed a sigh of relief.

She did it herself, pulled out more than 20 books from different bookshelves, and handed them to Tang Yan with the floating spell.

"All the books that mention the Foley family at length are here."

Tang Yan was a little shocked.

These more than 20 books were drawn from more than a dozen bookshelves, some in the forbidden book section, and some in the ordinary section.

So many books can be located accurately, really amazing.

She did not hesitate to give Mrs. Pince a thumbs up.

"You are really the best and most caring librarian I have ever seen!"

Mrs. Pingsi was a little embarrassed by the praise, and all the bad impressions brought about by Tang Yan's "chaotic" flipping through the book just now disappeared.

She looked at Tang Yan with a smile: "Professor Fuli, you look at it first, and then tell me what you need to find, and I will find it for you."

Tang Yan thanked Mrs. Pingsi, used the floating spell to put the books on the table, sat aside, and read carefully.

Most of the books that mention the Foley family have to do with fishing for magical sea creatures.

I read more than 10 books, but I didn't find a single one that was different.

She put the book she had just finished reading aside, reached for the next brown cardboard book with dark gold patterns, and took a look at the title of the book on it.

"Those Unspeakable Alchemy Products"

Is it a book about alchemical products?
Could it be that some kind of magical sea creature was used in alchemy products, and then the Fuli family was mentioned by the way?

Tang Yan opened the book without any hope, and found something he was interested in.

See page 126 that says so.

[When it comes to family guardian alchemy products, we have to mention a wizard named Yuval Foley.

In 1901, he created a magic alchemy product in the shape of a door that could protect buildings, which was named the Guardian Gate by Yuval Foley.

The guardian gate needs to use the body of the house elf as a material, and through a series of undisclosed secret techniques, it can be made into guardians.

The function of the guardian gate is to protect the building and the people inside from harm within a certain range.

It should be noted that the protection range of the guardian gate is related to the house elves.

The house elves that are used as materials, the guardian gate can only work in places that need to be protected during their lifetime.

Because house-elves are loyal to their families, most Guardian Gates protect family buildings.

And the intensity of the defensive effect is also closely related to the strength of the house elf.

It is guessed that the defensive power of the Guardian Gate can reach ten times the strength of the house elves, and at the same time, it will also have the original defense strength of the house elves.

Bonus: It has also been speculated that defense might have something to do with the house-elf's aptitude, but this has not been confirmed.

With its astonishing defense power and wide defense range, the guardian gate has become one of the most outstanding existences among guardian alchemy products.

However, in 1905, due to the bloody production process, the Guardian Gate was banned by the Ministry of Magic from being produced again, and then completely withdrew from the stage of history.

It is reported that after 1950, only the Foley family owned the last guardian gate.The other guardian gates lost their usefulness due to disrepair and were replaced by other alchemical products. 】

Tang Yan closed the book in his hand, a little lost in thought.

She thought of the door in the middle of the 4th and 5th floors of the Foley Family Castle, which she had destroyed by force.

On that door, there was the head of a house-elf.

Presumably it should be the guardian gate mentioned in this book.

That should be an alchemy product from a long time ago, its effect has been weakened by time, and its defense is very weak.But later it should have added a new function to it, which can help pass on the visitor's information.

The door looked eerie and sinister, but it was actually made by Yuval.

It can be seen from the new functions that Yuval has not given up on the continued research on the Guardian Gate.

Unexpectedly, Yuval is so good at alchemy!
Tang Yan realized that he might have thought in the wrong direction.

She immediately contacted the main god system.

"Help me find something related to the guardian gate in your data."

Soon, the main god system helped Tang Yan prepare a lot of materials.

She looked carefully and saw a lot of content that was not explained in the book in her hand.

You don't have to use a house-elf to make a Guardian Gate.

It is only because the house elves are loyal to their masters, willing to guard a certain range, and can meet the conditions of the guardian gate, so the house elves are used as materials.

But in fact, if you want to protect a family manor, it is better to use the blood of this family as the material.

In other words, using human life as an alchemy material, the guardian gate made of it is more powerful than one made of house elves.

The most important thing is that with the support of the power of blood, the defensive power of the Guardian Gate will not gradually disappear over time.

It can basically maintain the defense power of a thousand years.

Seeing this, Tang Yan already had a guess in his heart.

Yuval may not want to seize the body, but he is worried about the family after his death, and wants to leave a new guardian gate for the family to protect the family from external interference.
