The day before the Christmas holiday ended, William and Hermione returned to Hogwarts.

They did not take the water route this time, nor did they ride toads, so they probably will ride again in this life... The shadow in their hearts is too big.

So Ni used the phantom to show his appearance and sent the two to Hogsmeade. They rode the Thes and returned to Hogwarts safely.

This is the wizard's trip, safe and fast!

After returning to school, William and Hermione separated and returned to their respective college lounges.

But the lounge is empty, so everyone has to take the train to arrive at the school at night.

Bored, William went to the common room in Gryffindor to find the twin brothers.

The three sat down in the empty lounge, Fred pulled William and asked how he had submerged the Slytherin common room.

On the holiday, I saw William and Hermione having many little wizards under the Black Lake, and this incident had long been circulating.

The twin brothers are now particularly interested in this matter. They are inspired and are ready to flood Slytherin.

They plan to sneak into the Slytherin lounge and then blow up the toilet pipes.

But after only three actions, Percy reported it, so Professor Snape detained them for several days.

Now the twins have refused to talk to Percy.

William quickly explained what happened that day.

"So, we can't go to Black Lake in the future?" Fred sighed: "Those mermaid tribes are so revenge."

"It's okay, as long as we trade fairly with them." William leaned against the chair and said softly.

"Mr. Scarmand gave me some good methods to effectively improve my relationship with the mermaid."

"But you have to take your time to get along well with them, but don't go to Black Lake recently, especially Cedric, who is the number one enemy of the mermaids."

To be precise, all three of them were cheated by Cedric.

William threw a badge to Fred and George each, "This is the latest product I have made, called the warm-up badge."

After the two of them put the badge on their chests, they entered magic and a warm current came.

"It's very good, this thing can be sold well." Fred blinked excitedly, and he soon discovered the business opportunity.

“We can not only sell it at schools, but also at Diagon Alley.”

In the past, the most powerful product in their store was maps. This thing has high technical content and no one else can imitate it.

But their customers, only those students and parents, have too many audiences.

"Is it easy to be imitated?" George said worriedly.

He was afraid that things would be sold, and a copycat would appear in a few days.

"No, the core of this badge is an alchemy core engraved with ancient demonic texts.

Around the core, many hidden protection magics were cast, which were created by Nico.

It is difficult for others to crack it. If you force it to open it, the badge will be automatically destroyed."

There is no such thing as one year warranty in the magic world, and of course there is no so-called patent protection.

If you want to protect it, it depends entirely on the magic of the wizard.

William said this, and George and Fred were relieved.

Soon, the three of them discussed the sale price and plan.

"By the way, the forbidden forest psychedelic mushrooms are ripe. You can pick them these days." Fred said.

Psychedelic mushrooms are an extremely precious magical herb and an important part of the Fuling agent.

This thing is expensive like gold. William and the others don’t want to buy it in Diagon Alley, so they can only go to the Forbidden Forest to pick it.

"Okay, when Cedric comes to school, we will go to Forbidden Forest together." William said.

Several people were chatting, and the door to the lounge suddenly opened, and Harry and Ron came in through the passage.

"William, you are here. We searched around the library." Harry said in surprise.

"What, is there anything?"

"We just met Hermione. She was wearing a badge. Can you sell us one?" Ron envied.

"Of course, but cute brother, do you have so much money?" Fred smiled wickedly, showing a philandering face.

George also smiled and said, "A badge, the cheapest one is also for five gallons. You are the first customer, and only four gallons are charged for each person."

This price is not expensive. A fake wand on the market costs five Gallons, not to mention that William is a good alchemy product.

Ron muttered, it seemed that he really had no money, he thought he only had a few Sike.

"I'll pay Ron, but don't want his birthday gift this year." Harry took Garron out of his pocket readily.

Ron's birthday is March 1st, and it hasn't been long, so it's reasonable to be a birthday gift.

But little wizards usually give very cheap gifts, such as when Ron gives Hermione a quill for Christmas.

This is equivalent to giving away an automatic pencil, which is not the type that you can buy lead.

Compared with gifts like a few nat, the price of warm-up badges is indeed very expensive.

Ron obviously knew that he had a slightly red face and nodded, "That's it, Harry, I'll pay it back on your birthday!"

The twin brothers looked at each other, and a black question mark appeared on their faces, not knowing what to say.

William put the bag on the table, and Fred took out a handful of badges from it with ease.

Harry and Ron were picky and chose, and finally chose badges with Gryffindor's lion's avatar.

The two of them took them with satisfaction, and a warm feeling came.

Ron said happily: "This way I don't have to wear the sweater given by my mother. That one is too thick and inconvenient to move."

Every boy has a wandering heart.

William often wore a very thin coat in his previous life. He was as cold as a dog, and he was still there as demeanor and not warm.

It seems really stupid now.

William took out all the candies in his bag and signaled everyone to eat them together.

Fred laughed and said, "William, is it your Christmas gift again? Then we are not polite."

There was too much chocolate, and William distributed a lot of gifts to Fred and the others last year.

"So, William, have you asked?" Harry said hurriedly, sitting in the chair, leaning forward.

"That thing...is it a Philosopher's Stone?"

He asked Hermione before, but the girl didn't say anything and went back to her room.

"Yes, Nico said it was borrowed by Professor Dumbledore." William nodded.

He did not say that the Philosopher's Stone had no magic power anymore, Nico had told him that he could not tell anyone.

This is Dumbledore's plan.

"I just said that was a Philosopher's Stone!" Harry pondered for a moment, "What should we do? We should protect that Philosopher's Stone!

Kiro put the trolls in Halloween, he must have tried to steal the Philosopher's Stone!"

William glanced at Harry strangely.

"Harry, don't forget that Professor Dumbledore is at school and no one can steal the Philosopher's Stone from his nose."

"Or, do you think the Philosopher's Stone is in your hands... safer?"

"Uh, no...no, that's not what I mean." Harry shook his head quickly.

What William said makes sense. As long as Dumbledore is in school, he has no need to worry about it.

Thinking of this, Harry relaxed.

William smiled and signaled him and Ron to solve the candy too.

Ron bluntly chose the largest chocolate cake from it, and he seemed to be going back to his losses.

Harry also took apart a piece of chocolate frog and bit it down in one bite.
