This was the happiest time Harry had ever had.

Sirius was a very playful person. He led Harry and the others to fly over the Black Lake on brooms, used magic to build a giant snowman that was almost two stories high, and even made it move.

He was eager to try and wanted to use this thing to cause trouble for Snape, but before he even entered the castle, Professor McGonagall cast a spell and turned him into a snowman.

Take them to the forbidden forest and find the centaur friend.

However, the centaurs did not welcome them, especially when they saw Harry and Sirius. They angrily raised their bows and spears and chased them out of the Forbidden Forest. The four people and three cats were in a panic.

Ron plunged his head into the snow: "How exciting!"

Crookshanks squatted on his face and meowed a few times in response.

"They weren't so excited the last time I came. What did you do to them?" Harry and Sirius looked at each other and asked the same question in unison.

They both burst into laughter.

Hermione, with two owls on her head, looked at them unhappily.

Harry used to be such a stable person.

Why did he become so childish when Sirius came?

"James and I have tried to steal the bows of the centaurs several times before, but unfortunately we failed." Sirius sighed.

Harry smiled and answered him, "The Centaurs have strong healing magic and accurate archery. I tried to communicate with them but failed."

Sirius complained, "They're a bunch of old fogies!"

Hermione sighed softly.

What a pity that group of centaurs must have suffered, encountering two such restless generations in a row.

They also dived into the Black Lake in search of the giant squid.

But they were discovered by mermaids. That night, the little guy who had the honor of becoming the first flying mermaid in history spotted Harry at the first time and chased them ashore.

Sirius looked at Harry in disbelief.

Why does he have “enemies” everywhere?

They went to the Three Broomsticks to drink together.

After drinking too much, dancing in the bar.

George and Fred are the best at it.

Ron was envious, but with Percy's permission, he was still given a glass of butterbeer.

Crookshanks was forced to dance along, meowing so unpleasantly that Sirius didn't even notice a few more claw marks on his hands.

But even with such happiness, there are still regrets.

Sirius' regret was that he didn't find a chance to hit Snape with a club. In his impression, the slug had indeed changed a lot, especially in his abilities.

Harry's regret was that Lupin hadn't been able to join in.

The moon is full during Christmas.

The happy days passed quickly, and in the blink of an eye, Harry thought that the Christmas dinner had just ended, and the little wizards had already returned to school to prepare for the new semester.

Sirius could no longer stay at the school, he had no teaching position.

I could only say goodbye to Harry reluctantly.

He had to go back to the Potter house first. That would be their home from now on - of course, Lupin would also have a share, as the house couldn't remain in disrepair forever.

These were not the only things that made Harry happy.

Many of the ideas in his mind could be slowly realized after having Sirius.

The first weekend after school starts.

Harry received a package from Sirius, which contained many materials that could not be bought from Diagon Alley or Hogsmeade, such as the African tree snake skin and the horn of a two-horned beast that Harry had always dreamed of...

They are basically contraband.

There was also plenty of alcohol, and Harry ordered a portion of all the drinks he had and hadn't tried.

Hedwig and Bos carried the things back and forth more than twenty times, and they were so tired that they didn't even have the strength to peck Harry, so they lay straight on the table to rest.

I don't have much work usually.

But once you have a job, you're exhausted.

If Penny doesn't make dozens of pounds of owl rations, they'll go on strike!

Sirius didn't ask Harry why he wanted these things.

Maybe, like James, he would still be a little worried.

But this child's personality is like Lily!

The girl next to him also looks like Lily.

The little boy from the Weasley family was not as "humorous" as his two older brothers, but his personality was very similar to Remus.

In Sirius's opinion, this small group was too mature and stable.

Whatever Harry wanted, he gave him.

The godfather is the godson!

Gryffindor Common Room.

Harry sat alone in the corner.

Hermione and Ron were studying at a table not far from him.

In front of him, a pile of liquid was boiling in the crucible. He was studying potions - of course, not the orthodox potions in the textbooks.

It's the witcher's potion.

The wizards' potions are very good, but they are not enough for demon hunters.

There are no substitutes for Harry's favorites, such as Blizzard, Owl, and Oriole, not to mention other decoctions.

After all, wizards' potions are the results accumulated bit by bit over thousands of years of wizards' growth.

Not a match for the Demon Hunter.

The most important and crucial part of the witcher's potion is the base wine.

Almost all potions and decoctions require a special drink called "White Seagull", which is a mixture of various drinks and herbs.

What gave Harry a headache was.

There is cherry wine, but there is no mandrake wine - the mandrake in this world is a magical plant with magical powers.

You can only try it slowly with other drinks.

George and Fred came over.

"Hey, Harry." Fred had just greeted him when he couldn't help sneezing. If Harry hadn't used a spell to bind the smell around him, the strong smell of alcohol would have made all the little wizards in the lounge drunk.

"What are you doing? Drinking alone without us?" George exclaimed, reaching for a green bottle behind him. "What kind of wine is this?"

Harry glanced at it and replied lightly, "That's not wine, it's the venom of the Lobaworm."

It is a magical creature that lives on the bottom of the North Sea. Its venom is extremely precious and even more toxic than that of the eight-eyed giant spider.

George immediately pulled his hand back.

Fred looked carefully at a bottle with Polish writing on it: "What about this one?"

Harry took a look and nodded: "This bottle is indeed wine."

Fred was relieved and was about to pick it up, but Harry added, "But it has an alcohol content of 96 percent."

Fred's hands froze.

George said resentfully: "Harry, this is not called wine, it's alcohol."

"It is indeed alcohol, and many ordinary people use it to make cocktails." Harry corrected his mistake.

George was startled.

Fred touched his throat in panic: "Are all Muggles so strong? Even wizards would die if they drank it."

"What do you want from me?" Harry waved his wand, and the wine brewing in the cauldron disappeared. The previous recipe had failed, and he now had to adjust it again.

"We came here because we want to discuss something with you." George took a deep breath, carefully avoided the bottles, and squatted beside Harry.

Fred also lowered his voice: "Thanks to you, we have earned nearly twenty Galleons in the Forbidden Forest."

"We calculated that by next year, we will be able to collect a hundred!"

George smiled: "The Weasley Brothers Joke Workshop that can shock the wizarding world is about to be born, all thanks to you."

"It's your own ability." Harry watched two bottles of wine being poured into the cauldron. Some herbs flew over and were plopped in.

“No, no, no.” George shook his head, “Without the Forbidden Forest map, we can’t get so many materials.”

"And we heard from little Ronnie that the Marauder's Map originally belonged to your father. It originally belonged to you."

Fred sighed, looking resentful: "It means that we took your things and made a deal with you."

"Get something for nothing."

"A treasure trove for nothing."

The two of them sang the same tune, as if they had suffered a great loss.

Harry said nothing.

"So we want to ask you, is there anything we can do to help?" George asked tentatively, "Even though we are just little wizards."

"I'm poor and I don't have any skills. How about a 10% stake in the Weasley Brothers Joke Factory?" Fred said with hesitation.

It's not that they were reluctant to give up their 10% stake, but they felt that this was still unfair to Harry.

Harry waved his wand, and a bag of Galleons popped out of the Sorting Hat and fell into their hands.

It was so heavy that George, who was squatting on tiptoes, staggered.

"Harry?" George asked puzzled.

This big bag feels very much like Galleon.

"Two hundred Galleons," Harry said softly, "and I'll add another half of my investment."

George immediately put down the purse: "No, no, no, Harry, we don't need it..."

"Not yet." Harry shook his head. "I remember you two knew some alchemy?"

George and Weasley held their heads high: "Of course!"

"There is no alchemy class in Hogwarts." George praised himself, "But we are confident that even the seventh-year students who choose to practice alchemy in Beauxbatons may not be as good as us."

Fred pointed at his head, "When it comes to pranks, we are geniuses. People like you, Harry, true geniuses."

Harry said seriously: "As a shareholder of the Weasley Brothers Joke Shop, I would like to ask you to develop an alchemical bomb for me. I also have Professor Dumbledore's alchemy notes, I can lend them to you to take a look."

"Bomb? The Muggle kind?" George was stunned.

Harry nodded. "Yes, a magical bomb."

George picked up the purse and nodded: "No problem, I will draw up a contract later to discuss with Mr. Potter, who owns 20% of the shares of the Weasley brothers."

Fred frowned and said, "But should we change the name? The Weasley and Potter Brothers' Joke Shop?"

George agreed.

Harry shook his head gently, "No, no need to change the name."

The two of them were about to shake their heads and reject Harry's argument. They were not greedy people.

Harry pointed at them: "Weasley."

He pointed at himself again: "Brother."

George and Fred were stunned, then laughed and nodded: "Then we can look forward to the alchemy notes that brother Harry got from Professor Dumbledore."
