Sent Mrs. Pince away, Rosho once again devoted himself to the study of magic.

Although it was very difficult to extract the intermediate substance from the casting process, Luo Xiu felt that it was worth a try.

The second time he performed alchemy;

The third time he performed alchemy;

Fourth Alchemy......

Luo Xiu tried again and again, failed again and again, but until he came up with a better way, this was his only way.

In the course of the seventh attempt, Luo Xiu had already seen with his own eyes that the intermediate matter had stagnated for a moment, and at that moment, the intermediate matter had stopped transforming, and it was neither iron nor gold, but a new thing that existed independently.

But after this brief period of hope, the intermediate matter began to transform—it was transformed into iron and gold, and it itself vanished.

Still failed.

Luo Xiu tiredly put down the wand in his hand, he was exhausted.

"It seems that my research method is wrong, and I need to try again in a different direction, and it is impossible to extract the intermediate substance by interrupting the casting in the process of casting alchemy." Luo Xiu pondered depressedly.

And just when he was confused, a sound of paper came from beside him, and Luo Xiu followed the sound, only to see a worn-out notebook fluttering from the direction of the bookshelf in the forbidden area.

It was the books that came to the door again, and they were books that flew from the forbidden section of the library, and the last time Salazar Slytherin's "The Composition of Magic and Spells" was the whole book flew by himself, and that was because Barrow, the ghost of Slytherin, helped me.

"Smack!"

The notebook fell on the table, and Luo Xiu looked down, only to see that the title page of the notebook read "A Study of Alchemy", signed by Nicol Lemay.

"Nicol Lemay's notebook? Is it related to the knowledge I'm researching? Luo Xiu pondered, "But who sent the notebook to me this time?" Is it still Barrow the Bloody? ”

Looking up, he saw the shadow of Barrow the Bloody, a terrible ghost that flickered between the bookshelves and disappeared at the end of the passage.

"Mr. Barrow!"

Luo Xiu shouted loudly, picked up his notebook and rushed forward.

He finally caught up with Barrow the Bloody at the door of the library, and the old ghost had to look back at him.

"Aren't you afraid of me? Child, I'm covered in blood. The bloody man Barrow looked at Luo Xiu with a pair of empty eyes and asked in a deep voice.

"I'm not afraid, Mr. Barrow, thank you for helping me last time." Luo Xiudao.

"Helping you is also helping myself." Bloody Barrot said frankly.

"Help yourself? What do you mean by that? Luo Xiu asked.

Bloody Barrow smiled, "You and I are both from Slytherin House, your glory is the glory of Slytherin, and the glory of Slytherin is my glory." ”

"It's as simple as that?" Luo Xiu couldn't believe his ears, this answer was too hasty.

"It's as simple as that." Barrow the Bloody Man nodded and said, "Alright, continue your research, it's time for me to catch Peeves." ”

After saying that, the bloody man Barrow turned around and disappeared outside the door of the library, this time Luo Xiu couldn't catch up with him anymore because he walked through the wall.

Helpless, Luo Xiu had no choice but to go back the way he came, and sat back in his seat to study the notes of Nicol Lemay.

In his notes, Rosho discovered that Nicol Lemay was not a simple wizard, in fact, Nicol was very similar to Rohew, and he was also proficient in both wizarding magic and Muggle technology.

What's more, Nicol may have more knowledge of material chemistry than Rosho, and he also has more powerful magical abilities, which led Nicol Lemay to create the magical Philosopher's Stone.

The more he read, the more surprised he became, and he found that what he had been doing in the past few days was Nicol Lemay's life's research.

First the stone was transformed into metal, and then any substance was transformed into metal, and in the process of transformation, Nicol Lemay also discovered the "intermediate matter" discovered by Rosho.

"It is a materialized embodiment of magic and energy, a process of constant movement of energy and infinite changes in matter, just as the sun shines on a plant and causes the plant to grow new branches, which is evidence of the transformation of energy into matter." - Nicole Lemay wrote in his notes.

Further down, Nicol Lemay made the same choice as Rohew, and he was ready to pursue the "intermediate matter" and even capture this new thing.

At first, Lemay did the same thing as Rohew, he obtained the intermediate substance by constantly interrupting the alchemy, and he tried much more than Rohew, judging from the experimental records on the notebook, Nicol Lemay tried for 10 months, a total of more than 6,500 spells and interrupted, but still did not extract the mysterious "intermediate matter".

Seeing this, Luo Xiu breathed a long sigh of relief - thanks to seeing Lemay's notes, he stopped his endless attempts, otherwise this kind of wrong experiment would be too time-consuming and labor-intensive, and the gains would outweigh the losses.

Looking further back, Nicol Lemay began to change his mind completely.

Since it was impossible to extract the intermediate matter directly from the transformation of matter, he began to try to observe the intermediate matter step by step from the transformation of matter.

By slowing down the alchemy and allowing the intermediate matter to be revealed for as long as possible, he began to study the form and characteristics of the intermediate matter in an attempt to document its specific structure.

This method of research, while more reliable, is obviously more of a task—even if alchemy is slowed down to the maximum, the presence of intermediate matter is only in the range of hundredths to tenths of a second.

But the miraculous Lemay actually did the job with amazing perseverance, and it took him eight years and six months.

After observing the intermediate matter again and again, Lemay finally succeeded in describing the properties of this substance, and by focusing on its properties, he succeeded in extracting the complete intermediate material from the transformation process of the matter!

Once the properties of the Intermediate Matter are known, it can be prevented from transforming into other Matter, even if the Intermediate Matter only appears for a brief moment during the alchemy process, Lemay can capture it.

With Lemay's rut, Luo Xiu can naturally also capture the intermediate substance, which is undoubtedly great news.

According to Lemay's description, the extracted intermediate matter is very powerful, revealing the secret of the conversion of energy into matter, and also describing how one substance becomes another.

So with this intermediate substance, wizards can easily turn stone into gold, and not only that, but they can also do even more amazing things, such as reshaping their own destroyed bodies......

Nicol Lemay couldn't help but sigh that this magical intermediate substance is the most powerful magic in the world

Based on the powerful properties of the intermediate substance, Nicol Lemay gave this intermediate substance a simple but accurate name - the Philosopher's Stone.
