Karn had a rare moment of calm, and after a day of spending time in London with Hermione, he turned some of his energy into the world of ordinary people.

He separated several shadow clones, used transformation techniques and money to open the way, and obtained several identity certificates.

Then Kahn exchanged some pounds and went to the stock market to make a little money, and this year happened to be a good opportunity to make money; It's just that it's too late, and everything that should be earned is made by the financial oligarchs, and Karn can only make a little money from memory.

But even so, it could increase the wealth in his hands several times, and Karn could exchange the money for gold in exchange for magical resources in the wizarding world.

Half of the money earned was used to develop local power, and the other half was used to buy gold, and once his legal status was in hand, Karn would not have to rely on the help of a security company to rent a house as before, and he could reasonably invest in some businesses as a local citizen.

These things are naturally left to the shadow clone to do, and Karn now has a lot of chakra, and after separating three shadow clones, he can keep the shadow clone on his transformation technique for a whole day, and it is difficult for others to notice; And the side effects of the shadow clone can also be offset by the Desperate Virus, which can just sort out the impact of a large number of memories.

He just understands the memory of the shadow clone, and Karn will not deal with it if there is no accident, although there are wizards here, but Karn's ninjutsu is no worse than magic, especially the shadow clone + transformation technique, which is simply to take caution to the extreme, and the human bomb tactics that terrorists are best at are now used very easily by Karn.

Karn was a little more honest when he was in Diagon Alley, and the Ministry of Magic also sent the Aurors at the intersection of Diagon Alley and Tumbledown Alley to investigate the dark wizards of extreme terrorism.

The last explosion was fortunately in Tumbledown Alley, and it was the Dark Wizard who died, and it was hard for Fudge to imagine what kind of criticism he would have received if this happened in Diagon Alley, and perhaps the Daily Prophet would have devoted three pages to describing his incompetence.

So recently, almost all the Aurors have worked overtime, even if they can't find the mastermind behind the explosion in Tumbledown Alley, they must let the other party see the Ministry of Magic's determination to eliminate evil.

During the period before Hermione started school and Karn and other Boginbock's reply, he stayed at home in Diagon Alley very honestly, except for occasionally going out to buy a little food from the wizarding world, but unfortunately most of the magical desserts here need magic to be made, and there is no way to produce them industrially, otherwise Karn would be a dessert tycoon in the Marvel world.

Hermione was still a few days away from school

"Godfather Karn, take a look at my work."

When Hermione walked into the house, she proudly maintained the Levitation Charm with her wand, and the object of her Levitation Charm was two bottles of potions, a bottle of life and death water and a blood tonic potion; According to Hermione's personality, what can be shown to him is definitely the perfect potion that has been praised by Keitel.

"Looks pretty good, Hermione, give these two bottles to me as a collection, just enough to use if I get hurt."

Karn took the potion, not stingy with his praise, a young girl of her age who loves to show up, just needs the approval and praise of others, as long as Hermione behaves well, Karn will praise her.

As for Whiteface and Urging, having Keltell and Hogwarts professors was enough for Hermione not to be overly complacent, and if it didn't work, Karn would act as Whiteface a few times.

"It was originally intended to be given to the godfather..."

Hermione was very happy to receive the compliment, and during the time she consulted Keitel, she had basically finished learning the first grade potions and charms, although it was only a quick course, but she was very proficient in both charms and potions, and then Hermione had a lot of time to read books and become proficient in other courses.

Keitel also told Karn that Hermione could relax during the time before school and spend the rest of her time reading books each day for other things, although Karn thought that Hermione would continue to ask for no wasted time.

Karn could reveal a little bit about Hermione's condition to the Grangers, though, so they could help with discipline; But I don't know if it's Karn's delusion, the Granger couple doesn't seem to have asked him much about Hermione's condition lately, and there are some traces of 'free-range'.

.........

"Is this the elixir..."

Karn took the potion in his hand and looked at it, the luck potion can change the ethereal luck, but this kind of good luck is illusory, in fact, the elixir changes the user himself.

And you can't drink too much, if you take too much, it will have bad effects, such as arrogance, dizziness, and so on.

Karn didn't take it back directly after getting the traded items from Boginbock, but asked someone to check them to confirm the authenticity, and when he returned, he asked Phil and Isaac to check for signs of dark magic before he was relieved.

The elixir cannot be kept indefinitely, it is better to take it within the so-called shelf life, otherwise you will buy it and store it at home, and in the end it will be found that the effect of the medicine has expired, and the galleons spent will be lost.

However, Karn had space for a backpack, so he didn't have to care about that, and the elixir was not a masterpiece, and although it was difficult to boil, there would still be one or two bottles circulating in the market every year; And Karn believed that with Hermione's talent, he would definitely be able to brew a magic elixir in a few years.

So Karn divided the Elixir into three parts, which the owner of the Slug Magical Shop had told Karn that taking one-third of a bottle of Elixir at a time was the most appropriate dose.

Keep one for yourself, then take one and try it, and give the last one to Hermione.

As Karn's goddaughter, she was entitled to one-third of the Elixir.

As for the flesh and blood of the other magical creatures, Karn had preserved them well, preparing to study the feasibility of merging with the new Desperate Virus when he returned.

Karn was going to wait here until after school started, just in time to reply to the Ministry of Magic to open a shop, and Karn could also ask Hermione to help him deliver a letter to Dumbledore.

...............

Time flies, and in a few days it will be the first day of Hogwarts.

Karn also tried the elixir that day, and after drinking it, he felt his brain unusually awake, and other complex emotions were suppressed somewhat, allowing him to enter a 'more sane' state.

At this time, Karn wrote a letter greeting Dumbledore, which was about one-third of the greetings and praises, and a third of his yearning for Hogwarts, and finally wrote that he could not understand the sadness of the wizarding school as a Squib, and donated a sum of five thousand Galleons to Hogwarts.

Hoping to contribute to Hogwarts' educational cause, the envelope also contained a note on the transfer of funds from Gringotts, and whoever got it could take five thousand Galleons from Karn's personal warehouse.

It was only at the end of the letter that Karn spoke of his desire for magical creatures, asking Dumbledore where he could buy the Phoenix's blood and tissue, and he was willing to pay 30,000 Galleons for it.
