I swung my greatsword at Hogwarts

Seeing his jealous look, John shrugged and prepared to buy books first.

It's just that when he found all the books, he saw Mr. Weasley and Mr. Malfoy fighting.

The Weasley twins next to them cheered loudly, and if it wasn't for Malfoy who couldn't beat the big family, they probably would have rushed forward.

"What's all this called?"

John watched Mr. Malfoy's eyes go black when Mr. Weasley grabbed a copy of "Toadstools".

Hagrid came over to separate the two entangled people, and Mr. Malfoy uttered harsh words.

Throw the book into Ginny's cauldron.

"They are quite measured and know that they can't use magic."

It seems that the two of them fought very hard, but in fact, neither of them used magic.

John knew that these two people were afraid of being troubled by the Ministry of Magic. After all, using magic was not the same as ordinary fighting.

"My God, is there a fight here?"

Watson exclaimed, and then he remembered that his son seemed to want to buy books.

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

John saw that Mr. Weasley was being taught by Molly like a son, and his things were all bought, so he said goodbye to Harry and the others.

When saying goodbye, John saw an old book similar to a diary in Ginny's cauldron. After thinking about it, the Weasley family seemed to use old books, so he didn't think much about it.

The family is Muggles, and John can't floo away.

The family still visited London for a day before going back.

After returning home, John started to fiddle with the materials, and the materials that Hagrid bought for him were also delivered by mail in the next few days.

...

"These are wonderfully written."

John closed the book by Gilderoy Lockhart, which had a wonderful story.

Especially some of them have some hidden magic principles, let John read them all.

"Could it be that this Defense Against the Dark Arts professor is capable?"

Judging from Lockhart's wonderful story, this person's rich experience may be a very good teacher.

"It makes me look forward to it."

Putting the book on the table, John took out a piece of dragon tooth powder.

This thing is a dragon's tooth with a slight poison on it.

He mixed dragon tooth powder with other things to make a viscous liquid, and spread it on Iron Wick's sword.

Iron Wick's sword turned black after being evenly applied, and turned into a mirror after a while.

"Use dragon teeth to coat him with a demon-breaking effect, but I don't know what the actual effect will be."

John strengthened the sword of Iron Wick to destroy magic, so that even if it encounters magical creatures, it can cause damage to its scales.

Stretching out his hand to touch the blade, it was sharp but tough.

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

Some are exchange letters he sent to various alchemists, and some are letters from rune experts.

These are the results of his continuous efforts during the vacation. He wrote to various experts to ask questions and solve them, even the pharmaceutical experts.

The reason for this is because he was accumulating contacts in advance.

In the wizarding world, the support of seniors is also indispensable. Nicole Flamel also told him that he needs to better communicate with other people instead of working behind closed doors.

It has to be said that John's Hogwarts student status brought him a lot of convenience. Many of these experts are students from Hogwarts.

They are also willing to help others when it comes to helping students at their alma mater.

"Dear John, I am very moved by the improvement of Wolfsbane potion you proposed, and I hope to meet with you—Dharma Alex Belby."

"Where is Wolf's Poison Potion, you can go and have a look."

Dharma Alex Belby is developing the wolfsbane potion, he is a student from Hogwarts.

John was interested in his Wolfsbane Potion when he was looking for it. He remembered that the Wolfsbane Potion could make a werewolf become a werewolf and stay sane.

Holding the idea that werewolves are also poor people, John sent some of his thoughts over.

Unexpectedly, there was such a big response, Dharma Alex Belby wanted to meet himself in person.

And the location is at St. Mungo's Magic Injury Hospital.

John thought for a while that it would be okay to meet up, just to expand his network.

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

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

The LeMays passed away.

They didn't let John pass, they wanted John to remember them as they were alive rather than after death.

John is very sad that such a good teacher passed away like this.

There was no funeral or grand ceremony, only the witness of a friend, Dumbledore.

...

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

It's not in Diagon Alley, but in a red brick department store in London called Tao Tao Limited.

"Enter the hospital."

John explains his visit to a dummy in a department store window.

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

And beside the wizard, a thin man was recording the pain the man was going through at the moment.

He is Dharma Alex Belby, and he observes the reactions of werewolf bites.

John leaned over and took a look. The man was in pain, and his wound was sealed with white cream and silver.

"Silver can't cure werewolf bites, but Baixian provides enough nutrition for patients to endure the pain in the early stage."

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

"you are?"

He thought it was a kid from somewhere, and immediately said impatiently: "I'm not free right now, please leave."

John smiled when he heard the words, "John Wick, it's a pleasure to meet you Sir Dharma Alex Belby."

John Wick?

Dharma Alex Belby paused and looked at John in disbelief.

"Are you the student who wrote to me?"

He'd thought he'd be a seventh-grader, and being able to point out something he hadn't discovered must be gifted.

I didn't expect to have talent, but it was too enchanting.

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

"Forgive my blindness just now, Mr. Wick."

Dharma Alex Belby's attitude changed, becoming extraordinarily enthusiastic.

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

After observing the hapless wizard in front of him for a while, John walked out of the second floor after meeting with Dharma Alex Belby for the next letter conversation.

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

A lost Neville was walking in the corridor when he heard John's voice and looked over.

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

He was terrified of his best friend getting sick.

John shook his head to indicate that he was fine, but Neville's presence made John very strange.

"what are you doing here?"

"I'm here to visit my parents."

Neville looked downcast, and John knew his parents must be ill.

Now that they met, John and Neville went to the Spell Damage Department on the fifth floor.

Here, John saw Neville's parents, the excellent Auror couple.

They were tortured by Death Eaters, and eventually became crazy, unable to even recognize their own children.

Neville couldn't stop crying when he saw this scene, John sighed softly, and patted him on the shoulder to comfort him.

Voldemort and his minions have done too many crimes.

Finally they left the hospital, John said goodbye to Neville, and he saw Neville's grandmother waiting for his grandson there.

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

John nodded at her, and Granny Neville nodded slightly.

Leaving the hospital, John went back to prepare other things.

He remembered Wolfsbane Potion because it had appeared in Harry Potter's third year, and it was still made by Snape.

It seems that it has not been published yet, and he doesn't remember much about the details, but he vaguely remembers that the most important thing is aconitum.

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

A few days later, John sent his conjecture to Dharma Alex Belby by letter, and after a while, he received a reply.

"Success."
