Hearing that the Sorting Hat had placed Rosho in Slytherin among the four houses, Hagrid frowned in frustration.

The one he hates the most is Slytherin, and Slytherin is always home to some pretentious nasty guys.

When Hogwarts School of Witchcraft and Wizardry was founded a thousand years ago, the four founders had a great disagreement on the teaching philosophy, among which the founder of Slytherin, Salazar Slytherin, advocated the purest bloodline, believing that only the offspring of wizards and wizards were qualified to learn magic, while Muggle blood was too dirty, which was a stain on sacred magic.

Because of his philosophy, Slytherin House initially only admitted students of pure blood, but later generations of Slytherin gradually opened their doors to mixed-race and even Muggle children.

At the time when Hagrid was studying, Slytherin was not yet fully opened, and Hagrid, who was half-giant-blooded and half-wizard, was ridiculed by the pure-blood wizard descendants of Slytherin.

That's why Hagrid hates the house.

Now that he saw that the Muggle-born Rosho had been recruited into Slytherin, Hagrid was depressed and worried about Rosho.

"But the Slytherin megalomaniacs will laugh at Xiu." Hagrid desperately tried to convince Dumbledore, "Can you get the Sorting Hat to think again?" ”

Dumbledore shook his head, "No, Hagrid, don't worry, Snape will take care of Rosho." ”

Before Hagrid could reply, a deep voice came from outside the door.

"Yes, Hagrid, don't worry, I'll take care of this kid."

Following the prestige, I saw a thin, pale man with long greasy black hair striding in.

He was the Dean of Slytherin House, Professor Severus Snape.

"Professor Snape?" Hagrid was a little surprised, he didn't expect to bump into him here.

Dumbledore smiled lightly and beckoned to Rothew, "Come, kid, I've seen your headmaster, Professor Snape." ”

Rosho was already familiar with Snape, and he immediately walked over to meet him.

"Professor Snape." Luo Xiu greeted with a smile.

Snape's face was expressionless, his eyes cold.

"What's your name?"

"Luo Xiu."

"Well, come with me." Snape waved his sleeves, nodded to Dumbledore and Hagrid, and turned to leave the dining room.

Undeterred by Snape's cold exterior, Rosho followed Snape out of the dining room.

Before leaving, he turned back and grimaced at Hagrid and Dumbledore.

"You really let this kid join Slytherin?" Hagrid still hadn't accepted the reality, asking after Rosho and Snape had walked away.

Dumbledore smiled silently, his old eyes glinting with a sly sly.

At this time, Hagrid suddenly realized, patted his thigh and said, "Wait! How did Snape happen to be in the restaurant? You already knew the Sorting Hat was going to divide the Repair into Slytherin? Or is it all your arrangement? ”

"Ho-ho-ho......" Dumbledore laughed, but he didn't answer Hagrid's question.

Only the Sorting Hat, which was not far away, said in a small voice, "You've become wiser Hagrid, you've become smarter......"

——————

Rosho followed Snape out of the cafeteria, neither of them taking the initiative to speak.

The awkward silence lasted for a full five minutes before Luo Xiu was the first to break the silence.

"Why did Headmaster Dumbledore put me in Slytherin?"

Snape shook his head expressionlessly and said, "It's not Dumbledore who assigned you to Slytherin, it's the Sorting Hat that assigned you to Slytherin, no one can manipulate the Sorting Hat, not even Dumbledore." ”

"So the Sorting Hat must have told you to come to the cafeteria ahead of time?" Luo Xiu asked slyly.

"This ......," Snape was speechless, the child in front of him was smarter than he thought.

He didn't argue with Luo Xiu on this issue, but subtly changed the topic.

"I heard you've done Dumbledore a great favor, would you mind talking to me?" Snape still spoke with his cold emphasis, as if he had no feelings for anything in the world.

Luo Xiu didn't hide it, and told all about his creation of black technology equipment in Hagrid's cabin, and tricking Quirrell and Voldemort into taking the bait.

Snape listened with interest, carefully receiving every message Rosho gave.

"Did you build a weapon that was designed by Muggles?" Snape asked curiously.

"Yes, it's a Muggle design." Luo Xiu nodded, and then unbuttoned his shirt, "Actually, I was carrying a small sample with me. ”

It was the Ark Reactor he used to power the silver shield, a replica of the gap he had made for Hagrid's anti-magic armor.

"Oh, it's amazing!"

At this moment, even Snape, who had been expressionless, showed a shocked gaze, and he couldn't help but sigh: "Who would have thought that Muggles have such amazing technology!" ”

Luo Xiu smiled lightly: "Actually, it's not just Muggle technology, I used the alchemy in earth-based magic to create some of these metal elements, although the quantity is not very large, but it plays a key role." ”

"What?" Snape looked back at Rosho in shock, as if listening to a joke, "You made some metal out of alchemy?" ”

"Yes, Professor Snape, is there anything wrong with that?" Luo Xiu asked with a smile.

"Absolutely! How is it possible for an ordinary student, oh no, a student who has not yet received an education in magic, to learn alchemy? Alchemy is an extremely difficult technique! Snape said loudly.

The difficulty of alchemy in the wizarding world is far beyond the level of ordinary wizards, and even Dumbledore can only turn stones into gold with the help of the Philosopher's Stone.

It is for this reason that the Philosopher's Stone made by Nicol Lemay has become a precious treasure - the Philosopher's Stone can turn any metal into pure gold, and it can also create an elixir.

"Alchemy...... So hard? Luo Xiu didn't understand it now, he felt that alchemy was very simple.

As long as you recite the incantation and at the same time think of the structure of the atomic level of the gold element in your mind, then the matter in front of you will immediately change and change into gold - what's so difficult about that?

Since Snape didn't believe it, Rosho simply picked up a stone on the side of the road.

"Professor Snape, look."

He smiled, then waved his wand.

The structure of silica is sketched out in mind, and then it is converted into gold.

Almost in a second, the little stone underwent a qualitative change—it suddenly became golden, a tiny piece of gold.

Snape was dumbfounded, unable to believe his eyes.

And at this moment, Luo Xiu suddenly realized—he probably understood why alchemy was so simple for him, but so difficult for other wizards.
