After making up their minds, the two of them no longer mentioned topics related to the class schedule.

After Kyle finished his meal, they went up to the attic together, and Fred also took out a list of books with Lockhart's name on it.

"They are all Lockhart's books," he said. "The new Defense Against the Dark Arts teacher must be an admirer of his... maybe a witch like my mother."

"I see..." George pretended to hold an orange, as if he was holding a crystal ball that could foresee the future, "This year's Defense Against the Dark Arts class will definitely be a disaster."

"This doesn't require divination."

Kyle peeled open his "crystal ball" and put a petal into his mouth. "Is there any year where the Defense Against the Dark Arts class wasn't a disaster?"

"Oren is good." Fred glanced at Kyle subconsciously, "If he is not a dark wizard..."

"You're right." Kyle shrugged.

If we only look at the quality of teaching, Oren can even be said to be the best Defense Against the Dark Arts professor at Hogwarts in the past twenty years.

But unfortunately, he is a dark wizard, and a dark wizard who has bad intentions towards him... This is a bit unpleasant.

Thinking of the recent Defense Against the Dark Arts professor, they lost interest in continuing the conversation. George put the list of books in his hand aside and took out a rubber stick from the box in the corner.

Because the research on "Quick-Acting Skipping Candy" has been slow, Fred and George have been fiddling with their other joke product in the attic recently... the magic wand.

This was an idea that George came up with on a whim during his Charms class.

From the appearance, they are exactly the same as real magic wands, but if someone tries to use them to cast magic, they will randomly turn into some kind of rubber product.

With Kyle's help, they are almost able to make it successfully in the past few days.

The only problem now was keeping the fake wand stable, making sure it only changed when you wanted to cast a spell.

However, Kyle did not help with this problem... After all, everyone was together, he couldn't take on all the things, he had to leave something for Fred and George to do.

And when they are busy, I can have some peace and quiet.

Fred and George spent the entire morning trying different methods to maintain the fake wand's transformation.

Kyle was studying the new Hogwarts map nearby.

After two years in the map business, some people had already discovered the business opportunity and started to grab the business.

After all, this thing is not difficult at all, even lower grade students can make it.

Hermione had drawn a similar map last year, and if she could do it, then others could do it, too.

And unlike other products, the target audience of the map are newly enrolled young wizards who have no previous knowledge of Hogwarts.

When the products are the same, even if Kyle and others are "old brands", it is difficult for them to gain any advantages.

The others are fine, but Slytherin's market must not be lost.

Therefore, it is time for a major update to the map.

What he had shown Nico before was the prototype of the new Hogwarts map.

All he had to do now was simplify the method enough for mass production and distribute it to others.

It doesn’t matter if they have fewer functions, as long as they can move and display the route in real time, they can regain the advantage.

The three of them were busy with their own things and did not disturb each other. The scene was very harmonious.

But this harmony only lasted for a short morning.

Not long after lunch, there was a sudden burst of harsh noise outside.

A few minutes later, Fred, unable to concentrate, stuck his head out of the window and saw Ron yelling.

"Would you please be quiet!" he yelled.

Outside the room, Ron, who was flying on a broomstick, stopped immediately and stared at Fred's face with dull eyes, as if he had seen Snape dancing ballet, full of shock and disbelief.

Ron rushed back to the Burrow shouting, "Come and see, Percy has turned into George!"

Apparently he had mistaken Fred and George again.

"What are you talking about? What's wrong with me?"

But at this moment, the window on the third floor of the Burrow was suddenly pushed open, and Percy said impatiently: "Also, can you be a little quieter."

Ron stood there in a daze. He looked at Percy, then at Fred across from him. His already confused brain went into a complete standstill.

"When will our little brother become a little wiser?"

Fred sighed and said, "But George, I think I kind of understand how Percy felt before."

"Yeah." George said with a smile, "It's really hard to concentrate because of the noise outside."

"Then we will ..."

"Hey, stop talking nonsense, it's Ron who's making all the noise, we're usually pretty quiet!"

“That’s right!”

George looked at Ron outside the window with disdain, then seemed to have thought of something, and said with a grin:

"I suddenly had a good idea. Do you remember what Ron's wand looks like?"

"Of course I remember. It cost us seven Galleons." Fred raised his eyebrows. "So what you mean is..."

"Yes, that's what I meant..."

"Where does he usually keep his wand..."

"In the pocket of the robe..."

"But he doesn't wear robes when he plays Quidditch..."

"hey-hey……"

The two looked at each other and smiled wickedly at the same time.

Kyle shook his head and asked, "Didn't the fake wand fail yet?"

"That's why we need someone to help us test it." Fred said as a matter of course.

“Only if we know where the problem lies can we improve it better, right?” George also blinked.

Thinking of this, the two of them no longer had the mood to continue, and pulled Kyle to the open space outside the room.

In front of the Burrow, Mrs. Weasley was scolding Ron, asking him to keep his voice down and not disturb Percy who was reading.

"I really want to know what he's doing!" Fred frowned and looked at the locked window on the third floor. "He just got twelve OWL certificates a few days ago, but he's not very proud of it. He's even busier than before."

"This is very unusual." George said thoughtfully, "And I saw before that his name on the letter was pink. Although he explained that he had run out of ink, I still felt that something was wrong."

…

Several people came all the way to the Burrow.

Fred used the excuse of getting his broomstick to squeeze into the house.

When he came out again, he made a subtle "done" gesture to Kyle and George.

In order not to arouse suspicion, they did not go back, but went with Harry to a paddock on the hill and played Quidditch for a while.
