Snape never expected that the self-taught Muggle boy in front of him would really turn a stone into gold—although it was only a tiny piece of gold, and the purity of the gold was not high, but he did, and he did.

At the same time, Luo Xiu also figured out why he had learned alchemy, and he figured out why alchemy, which was so difficult for other wizards, was so simple to him.

Because he is more knowledgeable.

Not wizarding knowledge, but Muggle knowledge.

If you want to use the alchemy in earth magic to transform the essence of matter, then the wizard must know what he wants to turn into something, and since alchemy is a microscopic operation, then the wizard's understanding of matter must go deep into the microscopic level.

Luo Xiu knew the atomic structure of stone, gold, aluminum, lead, palladium, and uranium, so he was able to successfully perform alchemy and complete the conversion between substances.

But other wizards didn't have this knowledge, and they couldn't learn alchemy, not because they didn't have enough knowledge as wizards, but because they didn't know enough about Muggles.

At this time, Snape was still in a state of shock, and the cold Slytherin Dean became cold when he first came into contact with Rothew, and he stared at the piece of gold in Rothew's hand, suspecting that this was some kind of trick, not a real alchemy.

Rosho smiled lightly and tossed the gold in his hand to Snape.

"Professor Snape, please take a look."

Snape cautiously took the gold and looked at it carefully—it was indeed a piece of gold, and Rosho didn't use a trick.

"It's impossible, why can you learn alchemy so easily?" Snape's voice became a little hoarse in surprise.

Rosho smiled and said, "Professor Snape, I think the reason why I was able to learn alchemy so easily was because I was a very knowledgeable person in the Muggle field. ”

"Oh? What does that mean? Snape didn't know why.

Luo Xiu told Snape his experience without reservation: "Professor Snape, I think that alchemy in earth magic is a kind of magic that changes the nature of matter at the microscopic level, and in order to complete this magic, you must understand the structure of matter at the microscopic level, which involves Muggle knowledge......"

Hearing this, Snape's eyes narrowed: "Wait, are you saying that if we wizards want to perform some alchemy, we still have to learn Muggle knowledge first?" ”

After saying this, Snape involuntarily snorted coldly: "Hmph! What nonsense, it's a humiliation for wizards! ”

Luo Xiu shook his head and sighed, "Professor Snape, this kind of portal view of yours is too petty. ”

"What?" Snape glared at Rosho, "You dare to criticize me?" ”

Luo Xiu spread his hands: "Yes, I am indeed criticizing you. Professor Snape, I would like to ask you, there are Muggles and wizards, but is there a difference in knowledge? Is there a difference between Muggle knowledge and wizard knowledge? ”

"Of course it's different!" Snape said in a deep voice, "We're learning magic, magic magic!" ”

Luo Xiu smiled lightly: "You are a teacher of potions, so may I ask you, potions can cure diseases and save people, Muggle herbs can also cure diseases and save people, they are both healing and saving people, is there a difference in nature?" ”

"You're quibbling!" Snape's face grew darker.

Luo Xiu shook his head: "Is it a quibble that you will understand, wizards and Muggles are just two different ways of understanding the world, and mastering magic does not mean mastering the truth." In fact, with the help of knowledge of the Muggle world, some difficult and obscure magic can be cracked, and you can try alchemy again for yourself. ”

With that, Rosho described the structure of the gold element, and then asked Snape to try to turn stones into gold in this way.

Snape was not happy at first, but then he couldn't resist trying it, and under the guidance of Rosho, Snape actually succeeded in turning a small stone into golden gold!

"Really succeeded?"

Snape was overjoyed, and a smile appeared on his face for the first time.

But this smile was fleeting, so fast that Luo Xiu didn't have time to catch it.

"Well, Professor Snape, I didn't lie to you." Luo Xiu said with a smile.

Snape was convinced this time, he never thought that wizards' magic would need Muggle help.

"I have to admit that you have a unique perspective on this." Snape nodded in acknowledging Rosho.

Although he loves face very much, he admits that Luo Xiu's ideas are correct and ahead of his time.

Luo Xiu smiled and said, "Actually, the knowledge of Muggles helped a lot in this defense against Voldemort, I used anti-magic metal silver to block Quirrell's Avada Suo Curse, and at the same time, Hagrid used the weapon I made for him to subdue the troll......"

Snape had already been persuaded by Rosho and agreed, "Yes, it seems that Muggle knowledge does have its great things. ”

With that said, Snape had already led Rosho to the entrance to the Slytherin quarters.

It was said to be the entrance, but it was actually a metal shield with poisonous snakes hanging on the wall, and when he saw Snape, the snake on the shield opened its eyes and came to life.

"Migratory bird feathers, this is today's password." Snape whispered.

Before he could finish speaking, the viper swallowed the letter and crawled away, and the shield opened gently.

"Go inside, I've put you in Malfoy's dormitory." Snape said, "Now, is there anything else needed?" ”

Luo Xiu thought for a while: "I want to get the textbook as soon as possible." ”

Snape was surprised, he didn't expect Rosho to make such a request, after all, the other Slytherin boys started to have a headache when they heard the word "textbook".

"You'll have a set of textbooks, and I'll promise you'll receive them tomorrow morning." Snape said, and then couldn't help but reach out and pat Rosho on the shoulder, "Okay, now go and rest, it's not too early." ”

"Yes, thank you, Professor Snape." Luo Xiu said politely, and after speaking, he turned around and drilled through the passage behind the shield.
