"Can I learn the spells of your world, too?" Helena's eyes widened and she asked with some curiosity.

Xiwen felt the abundant magic reaction in Ravenclaw's crown, smiled and nodded, "You can try to control the magic in the crown first, and then you can learn spells when you can use it flexibly!" ”

"Flexible, right, is that what you're talking about?" Helena smiled playfully and reached out to the bookshelf next to her.

"Wingardium Leviosa."

She said in a pleasant voice.

Then, a heavy velope floated over and swirled around Helena. Its pages fanned like a large butterfly with many sizes.

"Okay, it seems that I underestimated you......" Xiwen put his hand on his forehead and smiled helplessly. Sure enough, with the magic, you're back to being the genius witch of Ravenclaw House. ”

"Of course, not to mention that I'm wearing my mother's crown now." Helena held her head up proudly. However, when it came to the tiara, her mood couldn't help but become low again.

Xiwen hurriedly changed the topic and said, "Speaking of which, did you just count that as a wandless spell?" ”

"Uh-huh, what else?" Helena pursed her lips and said angrily. "I'm in this form now, but I need to be able to pick up a wand first......"

"If Ravenclaw's crown can take on an illusory form, then a wand might be able to do it too." Xiwen laughed. "In the future, I will have the opportunity to study and study alchemy in this area, and then make a ghost wand for you to use!"

"Then I'll just wait for that day!" Helena laughed, her eyes crooked into crescents.

The crown that Ravenclaw left for Helena can be said to be an extremely special alchemical product, and Xiwen has never seen anything that directly changes the nature of an item, and can even be used by ghosts.

No, when it comes to items that can be used by ghosts, Xiwen suddenly remembered a knife he had taken from Barrow the Bloody.

That knife was obviously a special alchemy product, and could even be used by Barrow in ghost form, with the ability to injure souls.

In that confrontation with Barrow, Shivin miscalculated the situation on the field because he was not fully familiar with the characteristics of the ghost, so that he was almost injured by Barrow's knife, and finally escaped from danger through the form of Aikon.

It can be said that Barrow's knife is also a powerful weapon.

Driven by curiosity, Xiwen casually drew a circle in his hand and opened a golden circle of light.

This dimensional door leads to a room in the dungeon, and in the corner of the room there is a scimitar bound by layers of golden magic whips.

Sivan picked up the knife and led it into the Room of Need.

"Speaking of which, this knife should also be a magic weapon for ghosts, right?" Xiwen asked softly as he looked at the scimitar of the bloody Barrow.

"It's ...... That precious Machete of Barrow? Helena leaned over and frowned at the sight of the knife, her expression looking a little disgusted.

"Why do you need to tie it up?" She asked casually.

Xiwen explained to Helena, "This knife is actually very useful for its ability to hurt souls, but it doesn't obey discipline and even wants to get it out of my hand. So I tied it up. ”

"Can a knife still be fine?" Hearing Xiwen's words, Helena asked incredulously.

"I don't know." Xiwen shook his head and said. "But if it was also inscribed with a lot of runes before it was transformed into an illusory form, then it's normal to have some magic, right?"

"No, it shouldn't be changed by inscribed runes." Helena shook her head and said to Shivan. "I can still vividly remember that this is the knife that Barrow used when he died, and this is the same knife he used to stab me."

Xiwen's face immediately turned unsightly, and he frowned and asked Helena, "Why don't you destroy it?" ”

"Don't use it yet, it's not too late to destroy it after the research is finished." Helena took Xiwen's hand and spoke. "Speaking of which, I remember that Barrow was Salazar Slytherin's protégé, so it's likely that Slytherin made this knife for him."

"Is it that big?" Xiwen glanced at the mediocre scimitar again and asked in disbelief.

"That's right, it's big." Helena nodded. "At that time, Slytherin was studying a lot of taboo content behind the back of the other three founders, but in fact, my mother and the three of them knew very well what he was doing, but they didn't want to hurt the friendship between them, so they didn't stop it."

"At that time, he did a lot of experiments to make animals into living objects." Helena explained. "So it's not so much that the knife is fine, it's that it's an animal that has turned into a ghost with Barrow."

"It's like the ghost ......horses that the Headless Hunters ride," Shivin thought as he spoke.

"Quite possibly." Helena bowed her head slightly, and then explained to Xiwen.

"Ordinary animals can't have the obsession to support them to become ghosts because of their lack of intelligence. However, animals that have a deep affection for wizards may incarnate as wizards become ghosts, and this form is exactly equivalent to the appendages of wizards. ”

After listening to Helena's explanation, Xiwen completely understood the principle of Barrow's scimitar.

He picked up the scimitar, which had been wrapped in layers of magic whips, and carefully observed the lines on its body. If you look closely, you can see that the blade is not made of metal, but rather a layer of scales.

Possessing a winged snake in his Animagus form, Sivin is familiar with this scale, which is a type of snake scale.

He looked at the hilt of the scimitar again, and saw that it was in a wrapping shape, like the tail of a snake coiled around it, and that it seemed to have two dark eyes at the end of the hilt......

Xiwen shuddered, and couldn't help but say, "Did Slytherin directly turn a living snake into a knife?" It's kind of scary......"

"I remember you were the founder of your academy, right, you said that?" Helena raised an eyebrow and looked at Xiwen and said.

"Well, that's really ......" Xiwen laughed dryly and silently changed the subject. Forget it, I don't have the idea of making an animal into a living artifact, so this knife is useless for our research on the illusion of objects. ”

"Why don't you start learning Kama Taj's spells?"
