John looked at him with a look of jealousy, shrugged his shoulders and prepared to buy books first.

It was only when he found all the books that he saw Mr. Weasley and Mr. Malfoy arguing.

The Weasley twins next to him cheered loudly, if Malfoy hadn't been able to beat that big family, he would probably have rushed up.

"What's this called?"

John watched as Mr. Malfoy's eyes turned blue as Mr. Weasley grabbed a copy of Toadsley.

Hagrid walked over to separate the two entangled, and Mr. Malfoy let out harsh words.

Threw the book into Ginny's cauldron.

"They're pretty measured, they know they can't use magic."

It seems that the two of them are fighting very hard, but in fact, they don't use magic.

John knew that both of them were afraid of being troubled by the Ministry of Magic, after all, using magic was not the same as ordinary fighting.

"Oh my God, is there a fight here?"

Watson exclaimed, and only then did he remember that his son seemed to have to buy books.

When she arrived, she saw a mess of books, and Mrs. Wick looked for her son worriedly.

John watched as Mr. Weasley was taught by Molly to be like a son, and he had all bought his things, and he was separated from Harry.

As he said goodbye, John saw an old book resembling a diary in Ginny's cauldron, and thought that the Weasleys seemed to use old books, so he didn't think much of it.

The family was Muggle, and John couldn't get away with Floo powder.

The family also spent a day in London before returning.

Back at home, John began to tinker with the materials, which Hagrid had purchased for him in the next few days.

...

"It's a wonderful book."

John closes the book by Gilderoy Lockhart, and the story on it is wonderful.

In particular, some of them have hidden some magical principles, so that John can read them all.

"Could it be that the Defence Against the Dark Arts professor has what it takes this time?"

Judging from Lockhart's wonderful story, this man is probably a very good teacher with a lot of experience.

"It's something I'm looking forward to."

Placing the book on the table, John pulled out a piece of dragon's tooth powder.

This thing is a fire dragon's tooth, and it has a slight toxin on it.

He made a viscous liquid out of dragon's tooth powder mixed with everything else and applied it to the Sword of Tiwick.

The Sword of Ironwick turned a little black after being evenly applied, and after a while it turned into a mirror again.

"Use the dragon's tooth to coat him with a layer of demon-breaking effect, but I don't know what the actual effect is."

John strengthened the Sword of Iron Wick so that even magical creatures could damage their scales.

Reaching out and touching the blade of the sword, it was sharp and tenacious.

Putting the sword away, Basil brought him a lot of letters.

Some of them were letters of exchange from him to various alchemists, and some were letters from experts from Runiwen.

These are the results of his constant efforts during the holidays, and he writes letters to experts to ask questions to solve problems, and even the pharmacists do not let him go.

The reason why this is so is because he is building up contacts in advance.

In the wizarding world, there is also the support of his predecessors, and Nicol Lemay also told him that he needs to communicate better with other people, rather than behind closed doors.

I have to say that John Hogwarts' student status has brought him a lot of convenience, and many of these experts are students from Hogwarts.

They are also happy to help students at their alma mater.

"Dear John, I am very impressed by your proposal to improve the wolf poison potion, and I hope to meet you - Damo Alex Belby."

"Wolf poison potion, you can go and see it."

Damo Alex Belby, a Hogwarts student, was working on a potion of wolf poison.

John was interested in his wolf poison potion when he looked it up, and he remembered that the wolf poison potion could keep a werewolf sane after becoming a werewolf.

With the idea that werewolves are also pitiful, John sent some of his thoughts.

I didn't expect such a big response, and Damo Alex Belby wanted to meet him in person.

And the location is at St. Mungo's Hospital for the Injured and Wounded.

John thought about it, and it didn't hurt to meet each other, just to expand his network.

Putting the letter down, he picked up the last one.

After opening it, the expression on his face turned sad.

Mr. and Mrs. Lemay died.

They didn't let John go because they wanted John to remember what they were like when they were alive and not what they looked like when they died.

John was saddened that such a good teacher had passed away like this.

There was no funeral or solemnity, only the testimony of his friend Dumbledore.

...

St. Mungo's Hospital for Magical Injuries and Injuries, where John came.

It's not in Diagon Alley, it's in a red-brick department store in London called Taotao Limited.

"Enter the hospital."

John explains his intentions to the dummy in the window of the department store.

Then inside, he entered the second floor, where there was an unlucky wizard who had been bitten by a werewolf.

And next to the wizard, an emaciated man was recording the pain that the man was experiencing at the moment.

He was Damo Alex Belby, who was watching the reaction of a werewolf bite.

John leaned over and looked, the man was in pain, and his wound was sealed with white fresh and silver.

"Silver can't treat werewolf bites, but Bai Xian provides enough nutrients for patients to get through the early pain."

Damo Alex Belby was taking notes when he heard a voice and turned his head to look.

"You are?"

He thought it was a child from somewhere, and suddenly said impatiently: "I'm not free now, please leave." ”

John smiled when he heard this, "John Wick, it's a pleasure to meet you, His Excellency Damo Alex Belby. ”

John Wick?

Damo Alex Belby paused, looking at John incredulously.

"You're the student who wrote to me?"

He thought he would be a seventh-grader who would be able to point out something he hadn't discovered that he would be talented.

I didn't expect the talent to be there, but it's too demonic.

Although John is much taller than his peers, he looks like he is in the third or fourth grade.

"Forgive me for being blind, Mr. Wick."

Damo Alex Belby's attitude changed and became extraordinarily enthusiastic.

The other party invited John to visit his manor, and John naturally accepted.

After observing the unlucky wizard in front of him, John and Damo Alex Belby made an appointment for their next epistolary conversation, and John walked out of the second floor.

He saw a familiar figure in the hospital, and he said in surprise, "Neville? ”

A lost Neville walked down the hallway when he heard John's voice and looked over.

"John, are you sick, why are you here?" Neville was a little nervous.

He was scared that his best friend would get sick.

John shook his head to indicate that he was fine, but Neville was there, which made John strange.

"What are you doing here?"

"I'm visiting my parents."

Neville looked downcast, and John knew that his parents were probably sick.

Now that they had come across it, John and Neville went to the Spell Damage Section on the fifth floor.

Here, John sees Neville's parents, the wonderful Auror couple.

They were tortured by the Death Eaters and eventually turned into madmen who could not even recognize their children.

Neville's tears fell uncontrollably at the sight, and John sighed softly and patted him on the shoulder to comfort him.

Voldemort and his minions did too much.

Eventually, they leave the hospital, and John says goodbye to Neville, who sees Neville's grandmother waiting for her grandson.

The old man had a stern appearance, but would wait outside for Neville to come out.

John nodded at her, and Grandma Neville nodded slightly.

Leaving the hospital, John went back to get to work on other things.

He remembered the Wolf Poison Potion because it had appeared in Harry Potter's third year, when Snape had made it.

It doesn't seem to have come out yet, and he doesn't remember much about the details, but vaguely remembers that the main thing is that it is aconitum.

This thing is highly poisonous, and ordinary people will not use it easily on people.

A few days later, John sent his conjecture to Alex Belby to Damo, and after some time he received a reply.

"It worked."
