After selecting a wand for Black, Ollivander suddenly asked Darren, "How do you feel about those wands just now?"

"Well, you're right, it doesn't feel good. ”

"Not so easy?" Ollivander looked at Darren after a moment, "Can you feel the difference between these wands?"

"The difference?" Darren touched his head, "just a hazy feeling, indescribable." ”

"Then there is," Ollivander nodded, "which wand did you feel the most comfortable with?"

"Huh?" this Da Lun was stunned, just now he was owed, and it was enjoyable to pick it up, how can he remember which one is which, not to mention that in his eyes, the wands are basically the same, if it weren't for Ollivander every time he took out one, he would have to introduce the material of the wand body and the wand core, he couldn't tell the difference between the so-called dragon heartstrings, dragon nerves, phoenix tail feathers and unicorn hair, let him say now, how do he know.

"Oh, I didn't remember, I knew it was a unicorn hair," Darren could only tell the truth.

"Unicorn hairy ......," Ollivander muttered, bending down to take out a wand from under the counter, "is this one?"

Darren picked up his wand and tried to wave it, "I don't know, those unicorn-haired wands are too close, I'm afraid I'll have to take them all out and compare them before I can be sure." ”

"Well," Ollivander retrieved his wand and placed it on the counter, "Mr. Sean, remember what I did last time? ”

Darren looked at the wand on the counter, about a foot away, if it was the one he had been using, he was confident that it could be lit with a fluorescent charm even farther away, but he had just taken this wand once, and he really didn't know if it could be done, but what did it matter?

"Fluorescent flicker!"

As the spell sounded, the wand did not change in any way, and Darren lowered his head and stared at the wand with full attention, trying to mobilize the magic power in his body, reaching out of his body and rushing towards the wand.

"Fluorescent flicker!"

This time, Darren saw a subtle glimmer of light appear on the tip of his wand, which he would not have been able to detect if it weren't for the darkness in the store.

He tried again, "fluorescent flickering", but just like the last time, the wand still only emitted a little light, and no matter how much Darren concentrated, he didn't make any progress.

"Well, that's all there is to it," Darren said to Ollivanders, only to find him touching his chin with his hand, looking at him.

"For your age, your control over magic is excellent," he said, "and I'll say that using two wands isn't good for your studies, but it doesn't seem like much of a problem to you. ”

"What do you mean?"

"The unicorn hair is the core of the wand, and the magic it casts is usually the most stable, with the least fluctuations and blockages, it is the most loyal of all wands, and tends to maintain a strong bond with its original owner, and although I don't think it has identified you, at least from what you have just done, at least it does not repel you, which is a rare thing even for the new owner. ”

"So?" Listening to Ollivander's words, Darren felt as if something good was about to happen.

"Maybe this wand is for you, even if your previous one still works, who knows, wandology is a very esoteric science, even if I've been working on wands for decades, I can't know all their secrets, I think you'll provide me with some new knowledge, take it." ”

"Great, thank you, Mr. Ollivanders!"

"Wait," Ollivander said to Darren solemnly, "this wand is yours from now on, and I hope you will take good care of it, because you have two wands at the same time, which is very special, both for wands and for you, and I hope you will remember that." ”

"Yes, sir. ”

"Well, there is one more thing I should tell you in order for you to use the wand better," Ollivander continued, "even if you can match the two wands separately, but if you use two wands to cast a spell at the same time, they will respond to the user's mana fluctuations together, thus interfering with each other, and may not fail to cast the spell, but it will definitely make the spell less efficient and waste a lot of mana, I hope you will remember this." “

"So, if you have two wands at the same time, will it be the same?"

"Yes, as I said, wands are always in tune with the user's magic, and many spells don't require you to be able to use a wand in your hand, that's why, of course, if you're an adult wizard and you're just using your wand as a tool, it's not a big deal, but for your age, I'm afraid it's going to be a bit difficult, and I want you to take it well. ”

Hearing this, Darren felt a little embarrassed, the reason why he planned to get two wands was to have a backup in case of an accident, but if he couldn't carry them at the same time, it would be really a chicken rib, anyway, there was no hope in an emergency.

"But," said Ollivander slowly, "I think there's something that can help you. ”

“？！”

"In the process of making a wand, in order to avoid the interference of the maker's magic power, there is a material that can isolate the magic power, and if you use it to make a container to carry the wand, it should no longer conflict with other wands, but the user's fit with the wand will also be blocked, and," the white-haired old man looked at Darren, "This material is very expensive. ”

Oh, this guy is 100 percent a profiteer! Even if he didn't know that Darren had a lot of money, but there was a Blake, and Blake had just bought a wand and always had to pay for it......

"It's okay, I'll pay for it," and sure enough, a certain trench immediately stepped forward.

Eventually, Darren finally got a new wand, which Ollivander put in a special case and handed it into the hands of the new owner.

After coming out of the wand shop, the new topic of discussion among several people was naturally Darren, especially Lupin, who was interested in the young wizard who was about to become his own student, because even if he was not able to judge Darren's level of magic control by a wand like Ollivander, he knew how difficult it was to cast a spell without touching a wand, let alone a new wand.

As a conscientious teacher, it is important to fully understand the level of learning of the target audience, so that a realistic lesson plan can be developed so that most students can learn and acquire new knowledge efficiently, especially in schools like Hogwarts, where there is no syllabus available.

It's just that if Lupin uses Harry and Darren as a reference system, at least for the other students in the third year, I'm afraid the difficulty and pace of teaching will be a little too fast......
