After ten or five minutes,

Just as Jerry pushed Hermione's oversized suitcase to the corner of the box, the entire Hogwarts Express started slowly.

Since some wizards, especially the senior wizards, chose to stay in school to prepare for the exam, the number of young wizards on the Hogwarts Express was far less than when the school started.

Jerry and Hermione were the only two in this box.

After putting down the suitcase, the two of them took out a magic book from their carry-on bags at almost the same time.

Then, they sat together while reading and communicating.

The mountains and forests outside the car window began to slowly turn into snow-covered fields and Muggle villages as the train moved forward.

When it was almost noon, the train finally arrived at King's Cross Station in London.

The little wizards who passed through the platform nine and three-quarters, passed through the passage opened by space magic, and changed back to Muggle clothes, under the leadership of their parents, disappeared into the crowd.

At the entrance of the King's Cross platform, the Grangers had already arrived in a car early because they had received a notification letter from Hermione using the school owl in advance.

"Jerry, remember to call me!"

The car started, and Hermione stuck her head out the window and waved to Jerry, who was standing there.

"Yes, I will!"

Watching the car gradually disappear down the street, Jerry took a bottle out of his pocket and put a few strands of Hermione's hair in it that he had just snuck up on the train.

"When I make the compound decoction, it is estimated that no one will doubt me again!"

Pulling his suitcase with little stuff in it, Jerry walked straight to the subway entrance.

He would definitely not go back to the orphanage. Why would he go back? Now that there are traces of surveillance, he can't do anything when he returns to the orphanage, a waste of time.

Now that he has stayed in the small world for more than three months, and frequently uses the "enhance the brain" function, the number of his little red stars is not much left.

So, this time he plans to spend the two weeks of Christmas in Diagon Alley.

First of all, he needs to make purchases in Diagon Alley. Although there are many books in the Hogwarts Library, because they are all aimed at young wizards, many magic books that are dangerous or adult wizards are basically placed in the forbidden area. .

But those bookstores in Diagon Alley don't have these restrictions. As long as you have Kim Galleon, then he can't restrict you from buying books.

Secondly, now that there are traces of his body, and he has no ability to remove it, only Diagon Alley is a place where he can freely use magic during his vacation.

Jerry also inquired about things like traces before the holiday.

According to some senior Slater seniors, in fact, the Ministry of Magic cannot accurately monitor whether you are using magic, but can only monitor whether there is magic near your location.

If you are in a place full of wizards, the Ministry of Magic cannot judge even if magic is used.

Just like they can use magic at home, because both parents are wizards, as long as the parents don't say anything, the Ministry of Magic thinks it is the magic used by the parents of the little wizards.

Therefore, Zingsi is far more restrictive for young wizards born in Muggles than young wizards from wizarding families.

Because little wizards from Muggle families basically have no wizards living nearby, as long as they cast magic, they will be monitored by the Ministry of Magic immediately.

That's why, after Dobby performed magic at Uncle Harry's house, the Ministry of Magic thought it was Harry's violation.

Harry was the only wizard in the entire community, and the Ministry of Magic naturally judged that Harry had performed magic.

Taking the subway to Charing Cross Street, Jerry quickly found the Leaky Cauldron that Professor McGonagall took him to before.

After paying fourteen gold Galleons, he was led by the boss Tom to a unique old room on the second floor.

Next, he will spend two weeks in this room.

After putting away his luggage, Jerry didn't go to Diagon Alley immediately, but went downstairs and ordered a hearty lunch first.

After lunch, he began to take a good stroll in Diagon Alley.

Last time, Professor McGonagall was there, and he didn't actually visit many places. This time, he will definitely check all the shops except Knockturn Alley.

Since Knockturn Alley is relatively dangerous, he does not plan to take risks for the time being.

"Lacewings, leeches, sap grass, amphorae, powdered bicorn horns, and fragments of African tree snake bark..."

Jerry recalled the compound decoction formula he remembered in "Strong Potion" before, and headed to the herbal shop in Diagon Alley.

It takes about a month to brew the compound decoction. In order to prevent accidents, Jerry intends to make a few more pictures.

The compound decoction is a very complex and uncommon potion. There are many kinds of herbs and it is not cheap, so few people know about it, and few people use it.

Even though there was Professor Quirrell's medicine field in Jerry's box, which saved a lot of herbs, when he bought all the remaining ingredients, it cost more than two hundred gold Galleons.

Jerry made a preliminary estimate that if all the ingredients for a pair of compound decoction were purchased alone, it would cost at least one hundred Galleons.

That's almost the equivalent of a month's salary for a typical official at the Ministry of Magic.

Unless there are special circumstances, no wizard would spend a month's salary to buy these expensive medicinal materials to refine a potion that can only last for about a few hours.

Therefore, in the wizarding world, the compound decoction is also one of the rare types of potions.

After buying the potion, he went straight to the largest bookstore in Diagon Alley, Lishen Bookstore.

"Sir, what book do you need to buy?"

Seeing Jerry entering the door, a clerk immediately ran up enthusiastically.

Jerry didn't talk nonsense, and directly took out a bag of gold Galleons that had been prepared a long time ago and placed it on the table:

"I need "Standard Spell, Level 2", "Standard Spell, Level 3", "Standard Spell, Level 4", "Standard Spell, Level 5", "Standard Spell, Level 6", "Standard Spell, Level 7" , "Intermediate Transfiguration Guide", "Advanced Transfiguration Guide"..."

In one breath, Jerry reported all the textbooks related to magic, spells, and potions that he knew from grades 1 to 7.

Now that you have money, why do you need to do it step by step? It's better to buy it all at once and go back and study it slowly~www.mtlnovel.com~ Although the effect of self-study is definitely not as good as the effect of class, he is still a person with some foundation now. , plus the "refreshing" function, it can still have some effects.

Just like some high-level magic spells, even if the power he used does not meet expectations, as long as he uses it successfully, it can sometimes save lives.

And not only textbooks, but also some other books that were not available in the library, he planned to buy them back and put them in the villa in the box, and then read them slowly when he returned to the main world.

Knowledge is power, especially in the wizarding world.

These magic books are the real treasures, but unfortunately his Jin Galleon is probably not enough.
