The Hogwarts library is located on the fourth floor of the castle, and at the end of the corridor, you can see a large and magnificent door, from which you can enter the treasure trove of hundreds of books.

This was the first time Luo Xiu had come to the Hogwarts library, and he could already smell the fragrance of the scrolls before he even stepped through the door, the library was open during the day, and not far from the door stood an old witch with a stern face.

The old witch had long black hair coiled behind her head, a pair of eyes flashing with a sharp gaze, she had a hooked nose, and her thin lips looked very mean.

Rosho knew her, she was the librarian Irma Pins, and everyone used to call her Mrs. Pins.

Seeing Luo Xiu coming in from the main entrance, Mrs. Pins muttered impatiently, "There are also students who come to read at noon?" The sun really came out in the west. ”

"Hello Mrs. Pince." Although he could hear the unkindness in Mrs. Pins's tone, Luo Xiu nodded politely.

Mrs. Pince said angrily: "Be careful when you read, if you dare to stain my book, I will want you to look good!" ”

"Understood." Luo Xiu nodded slightly, then turned and walked towards the bookshelf, his current side quest required him to read five magic books, but his subjective desire was to go further in alchemy.

By learning alchemy in earth magic, Luo Xiu has been able to skillfully convert stones into metal, but due to his limited mana, the number of each transformation is not particularly large, and it is only converted from stone (mainly composed of alumina, calcium carbonate or silica) into metal, and Luo Xiu can't do the transformation between other substances.

But since alchemy can transform stone into metal, it is also possible to transform one element into another, and the significance of this is very significant.

Now Luo Xiu's understanding of matter is still limited, and he has not come into contact with some extremely rare substances, but if Luo Xiu comes into contact with the constituent substances of vibranium, gravity and even infinite stones in the future, and understands the microstructure of these substances, then using the properties of alchemy to directly transform matter, wouldn't it be easy to transform the rich substances on the earth into these rare elements?

Thinking of this, Luo Xiu began to search along the narrow passages of the library, first coming to the reading area of earth magic, and then selecting the content about "alchemy" from it.

And not long after Rosho entered the library, Hermione also followed, she was never willing to fall behind others in her studies, if there was only one person left at Hogwarts to study, then that person had to be Hermione!

Mrs. Pince didn't welcome Hermione's arrival, though, and she even frowned.

"Oh, what's going on at noon today? A messy kid wasn't enough, but there was a little girl. Mrs. Pince stretched her face, ignoring Hermione's identity as a girl, and said in a mean tone, "Hey, little girl, you'd better be careful when you read the book, do you hear?" ”

"Okay." Hermione nodded.

This wasn't Hermione's first visit to the library, and she was already familiar with the stern Mrs. Pince, who she was, and knew that she valued the library's collection more than her life.

After entering the library, Hermione didn't go to pick up the book first, but crept behind Luo Xiu, wanting to see what Luo Xiu was reading.

As the saying goes, knowing oneself and knowing one's opponent is invincible. Only by figuring out what areas Luo Xiu was studying could Hermione beat him in the same field.

While pricking up her ears to listen to Luo Xiu's movements, Hermione tiptoed towards the bookshelf, she sly and Luo Xiu across a shelf, quietly looking at him from the gap between the two books.

"Elemental Magic...... Why is he looking at this? After seeing Luo Xiu stop in the area of the Elemental Magic Book, Hermione pondered in confusion. Since the first-year Hogwarts curriculum didn't deal with elemental magic, there was no reason for Luo Xiu to read such a book.

"What a strange guy!" Hermione frowned in thought, then leaned on the bookshelf and continued to peep.

Unexpectedly, at this moment, a gloomy voice sounded from behind her: "Are you planning to read like this?" That's how you read books? ”

"Ahh Hermione gasped in fright, and quickly turned around, only to see Mrs. Pince appear behind her at some point, staring at her with a cold gaze.

"Lady Pince, I ......," Hermione said hesitantly.

Mrs. Pince didn't give her a chance to defend herself, and said sternly: "If you don't come to read the book, then I can only ask you to go out!" ”

With that, Mrs. Pince waved her hand, and a floating feather duster flew over, threatening to hit Hermione on the head at any moment.

"No, you're mistaken, Mrs. Pince, I'm just looking for a hard-to-find book." Hermione hurriedly pulled out a random copy from the bookshelf and forcibly explained, "This is it, I just found it, this is it." ”

"Hmph, I advise you to be honest, otherwise I can only ask you out!" Mrs. Pince said in a deep voice, and then turned away with a floating feather duster.

Hermione breathed a sigh of relief when she saw Mrs. Pince walk away.

And at this time, another voice sounded from behind her: "Scolded, right? Haha......"

Hermione looked back angrily and saw a gloating face from Rohew.

"It's none of your business!" Hermione replied angrily, she wanted to smash the heavy book in her hand at the bridge of Rosho's nose, but she didn't dare, if she did, then Mrs. Pince would definitely kill her.

However, as she spoke, Hermione glanced at the five books in Luo Xiu's hand very cleverly.

Nicol Lemay and Alchemy – one of the books is of this name.

"Alchemy? What the hell is this guy working on? Could it be that he is a fellow who covets glory and wealth, and delusionally wants to learn the trick of turning stones into gold that is as difficult as climbing to the sky? Hermione muttered to herself.

Luo Xiu didn't give her a chance to ask questions, and walked to a window seat with the book in his arms and sat down quietly.

As his research was about to begin, he gave his research a title, "From Alchemy to Elemental Transmutation".

Before starting to read, Luo Xiu clicked on his skill bar.
