Christmas is just around the corner, Hogwarts is covered in several feet of snow, and the Black Lagoon is covered in hard ice.

In the morning, William and the others left the castle after eating, ready to go to the Black Lagoon to catch a mermaid.

If you just look at this proposal, I don't know if I thought it was the twins' idea, but in fact, I wronged them.

The two of them were now busy thinking about how to take off Quirrell's scarf and what mermaid to catch.

It was Cedric's suggestion, who insisted that Christmas was a good holiday and that something festive should be made.

So he proposed to fish for mermaids, hang them on the Christmas tree, watch them as fish models, and put them back when the dinner was over.

Don't look at Cedric's usual pretending to be an honest man, but he is actually really wilted.

His real intention was to catch the merfolk and make a wand core with a few hairs.

Cedric had never tried mermaid hair before, and his curiosity had flares up again.

And he didn't want to take the risk alone, so he dragged William and them, so that the deduction of points was also deducted by everyone.

In William's opinion, Cedric will be killed either by someone or by his hairy magical creatures because of various acts of death.

"Can mermaid hair make a wand?"

Walking on the road, the wind howled, and William tightened the collar of his thick clothes.

He regretted it when he walked out of the door, it was too cold outside, and he couldn't wait to go back to the dormitory immediately to pack the bed.

"Of course you can, even if it's the hair of a centaur or a girl. However, it is very sensitive, and Mr. Ollivander rarely uses these things.

I'd love to give it a try, maybe I'll have a clever reaction. Cedric said seriously.

He also used the armpit hair of a troll, the same troll that William had killed.

It's a pity that no one buys the wand of the troll's armpit wand core, and the reaction is too slow, as if the IQ is not online.

William smiled: "Actually, I also have a genius idea, I have been thinking about the material matching of the wand for a long time, and I want you to help me make it." ”

"What's the match?" Cedric rubbed his hands together, regardless of whether he could cast the magic or not, he would do it first.

He doesn't like Mr. Ollivander who only likes to work with certain materials.

"The outer material is a polyethylene shell, and the rod core is two layers of erbium-doped silica with different refractive indices.

Let me tell you, the benefits of such a rod core are also obvious.

The spell emitted from the hand can achieve total reflection conduction in the wand, which not only reduces the loss, but also amplifies it, and the power is stronger than six!

That's the strongest wand! ”

“……”

Although Cedric understood every word of William, he didn't understand it at all.

Cedric decided to ask Professor Kerry Dick Bubbaji about what polyethylene was and what erbium-doped silica was in his next Muggle Studies class.

Professor Bubbaji is an expert in this area, and is said to have studied in the United States for seven years and is a graduate of Claydon University, where he has seven doctorates.

The last time Cedric asked what an atomic bomb was, Professor Bubbaji told him that it was a special Christmas firework with a beautiful pattern.

When the twin brothers found out, they wanted to buy one and release it at Hogwarts.

As they were about to leave the castle, they ran into Professor Quirrell.

In the snowstorm, Quirrell was covered in a thick metal shell, and two small short hands were exposed.

Looking at it from afar, I don't know and think that he stole someone's garbage can and put it on his body.

"Armor...... It's too heavy...... Inconvenience. Quirrell stammered. Don't think about it...... Strike again...... I! ”

The twin brothers are provoked by Professor Quirrell, and the two use their magic to control giant snowballs and smash them on Quirrell's head.

But the thick shell blocked the attack of the two.

Professor Quirrell narrowed his swollen eyes and took a bite of the black bread in his hand, he didn't eat the school food anymore for fear of being drugged by the students.

Quirrell laughed, and suddenly burst into tears.

"There's no next time, no more, I'll be leaving soon...... Hey. ”

Several of them sensed that Professor Quirrell was crazy and fearful of being touched, and left in a hurry.

After leaving the castle, George exclaimed, "It seems that no one can take this bounty. ”

The amount of the bounty issued by William has risen to one hundred and twenty Galleons, and if no one can take it, the money will still be his.

"You've been expecting this for a long time, haven't you?" George asked.

William nodded.

If Quirrell really wanted to hide what was under his scarf, it would be enough for the little wizards to see.

As for why it hurts...... Quirrell may have strength, but he only pretended to be a waste before, and in order not to be exposed, he could not show his extraordinary strength, so he could only continue to withstand attacks.

"We're going to stay here for Christmas and continue attacking Quirrell." Fred laughed.

The Weasleys are going to Romania to visit Charlie, and neither the twins nor Ron will be returning home.

The twins sent back so many Galleons every month, and their family's situation was alleviated a lot, and a few people could still afford to buy tickets.

But Mrs. Weasley insists on exploring the trail first, and it seems that it has become a runaway Jurassic Park.

"Don't be stupid, do you think Professor Quirrell will stay at school for Christmas?" William shook his head, "He's going to leave school to recuperate." ”

"Damn!" It was a pity for the twins to miss this opportunity.

As they approached the Black Lake, they ran into Hagrid again.

Hagrid carried a large fir tree on his shoulder and walked quickly towards the castle.

"Hagrid, do you need help?" William asked aloud.

Hagrid pulled his head out of the branches, and his furry face smiled, "No, I can do it, it's easy." ”

Hagrid hummed a happy ditty as he said happily, "Why are you going?" ”

"Let's go...... Take a stroll. George lied.

They didn't want Hagrid to know about running to the Black Lagoon to catch merfolk.

Magical creatures are Hagrid's favorite, and what if a mermaid is also a good friend of his.

Hagrid looked at the people strangely and said solemnly, "Don't go to the Forbidden Forest, it's dangerous." ”

"We're not going," Cedric said, waving his hand, "just take a walk around the Black Lagoon." ”

"Okay." Hagrid nodded, as long as he didn't go to the Forbidden Forest.

"Let's go to the restaurant after a while, it's beautifully decorated. Professors McGonagall and Flitwick are there, busy setting up the Christmas decorations, and you'll be surprised. ”

Several people hurriedly agreed.

"By the way, see Harry?" Hagrid patted his body, and the thick snow shook down from him.

"At this point, Harry should be in Potions class, right?" Fred smirked.

"yes, Harry's favorite potions class, the old bat will love him by the cauldron." George gloated.

Hagrid sighed, seeming a little worried.
