No one can disturb my retirement life in the Red Mansion

Dumbledore looked at the number. So, Lupin was saying that he spent 70% of that? Was that a lot?

He really didn't remember how much money he had spent. Both old Potter and James Potter were generous people. They were brave Gryffindors who had donated countless times for justice. However, Lupin was right. That was not Harry. Harry was not an adult. If he really traced the money he had used, he really couldn't explain it.

However, he has no private property, including the books here, which all belong to the school. He is just reading them. If he dies, these books will have to return to the library and wait for the next principal to rearrange the place.

How to pay back the money? Dumbledore was in pain. He had never been short of money in his life, so he had never thought about how to make money.

"Think about it carefully." Lupin lowered his head and went out. It was enough to get the idea across. You couldn't force Dumbledore to pay the money now. He couldn't possibly pay it.

It is easy for wizards to make money, especially for a great wizard like Dumbledore. He holds several positions, and these positions will give him some allowances. In addition, he has researched twelve uses of dragon blood when he was young. He has communicated with many wizards. If he wants to make money, it is easy. However, in the past fifty years, his main goal has been to fight against the mysterious man, and he has never thought about making money.

He looked up at the former headmasters, and finally saw the ancestor of the Black family, who was known as the most unpopular headmaster in history. Although he was not very popular, he really knew how to make money.

"Or, you can make some shampoos or hair growth products like Potter's grandfather did. In this way, you can give the patent to Harry, and Harry can make money without doing anything. Then no one will have the right to question you." Old Principal Black was busy giving advice. This was an easy task for him.

"You can also ask little Harry. As long as he admits that he agreed to donate, you don't have to worry." Another headmaster said slowly. He and Dumbledore were both scholars, and they felt that it was too unbecoming for a scholar to make hair toner and shampoo. The main thing was that the headmasters above all believed that Dumbledore would not embezzle little Harry's money.

Dumbledore actually wanted to find Harry, as long as Harry admitted that it was he who donated it to the Order of the Phoenix, then he wouldn't have to worry. But he didn't dare.

Yes, he suddenly didn't dare to do it. If he really did that, Lupin, Harry, little Petunia's friends, including old Foster, would look down on him. He spent an orphan's inheritance and wanted the orphan to admit that he did it voluntarily. If that happened, he would also look down on himself, right?

He lowered his head and sighed, thinking that maybe old Black was right. He should do what he was good at. He had made remarkable achievements in magic runes and alchemy. He could ask old Foster.

Old Foster, now a businessman, went immediately to the principal's office, where they had a long discussion.

Foster & Company had a plan, so they also designed a list of problems. Knowing Dumbledore's idea of ​​completing Harry's inheritance, the old man picked out three special projects, which were independent projects. However, they were not magic runes or alchemy, but potions.

But it is also true that in addition to the toy company and pet food company, the most important thing about Foster's is a household liquid company. It sells potion formula liquid, which is further processed in the Muggle world. Several famous brands in the world are their customers.

This is actually the biggest source of income for the Foster family, because household chemicals are really needed by everyone, and no one can escape. Although there are also projects for gold training, such as toy design, the profit is too small, and the big one is the magic communication that Ou Mengmeng wants. Now that the magic world has a mature gathering place, it is not difficult to realize the magic of wired communication.

After all, Sirius modified a motorcycle, Weasley modified a car. There is also the Hogwarts Express, which are very interesting examples. If this is done, old Dumbledore will be famous in history. Although he doesn't care about this. The main thing is that the money is huge. Of course, the investment is also huge. He thinks that if Harry gets it, he will just be in partnership with others, and it will be a bit annoying to operate.

He had the same idea as Old Black, because when they advertised, they couldn't say that this was a product of Dumbledore's research. Even if Dumbledore didn't mind, they, the students, would be embarrassed. So they had to choose something that Harry could also make. Since it was in Harry's name, they might as well be good people to the end. Let his grandson inherit his family's business! He liked to think of ways to use human hair.

Whether you start your own company or do something else, it’s easy to write advertisements. It’s reassuring to say that the product is produced by the grandson of the inventor of hair softener.

Of course, he wouldn't tell them, because the liquid would be sold to the Muggle world anyway, and it would be much easier to use Harry's name than Dumbledore's.

Old Foster definitely had the capital to fool people. Anyway, they signed the contract when they left the office, and really didn't waste any time.

So for the rest of the holiday, Dumbledore began his hard work as a worker.

Although when it comes to inventions, the brain is most active when one is young. For example, didn’t old Potter invent the hair softener in school? That was because people around him really needed it, and then he started researching.

The research ability of senior researchers is not a problem. What is lacking? In fact, sometimes it is really about choosing a topic. After choosing a good topic, students will study similar products on the market and find the main research direction. At this time, the advantages of senior researchers will be revealed, because they are experienced. They have seen a lot and used a lot. Many things are just a layer of window paper for them.

Foster has a step-by-step approach to its industrial layout. These three projects, for example, have been decided long ago. Although researchers have not yet been selected, the preliminary preparations have been arranged.

Therefore, in the high-tech laboratory of the Muggle world, Muggle wizards gathered together to form a complete preliminary classification research experiment. So they have scientific experimental data of all similar products on the market in the wizarding world.

What Dumbledore has to do now is to thoroughly understand the preliminary information prepared by Foster's Company and then create a groundbreaking product.

After taking a look at all the prescriptions, I knew the composition of the ingredients. Then I looked at the three specialties of Old Foster, one is a shampoo that can relieve hair loss; one is a hair growth potion; and one is how to perfectly mix the softener into the shampoo without any magical reaction, so as to achieve the softening effect of Hermione's hair during the shampoo.

Although Dumbledore is old, he is actually in good spirits. This time, Ou Mengmeng found the Gaunt family ring before him, so the old man did not risk wearing it. Naturally, he was not harmed by magic, and his body and energy were not affected. So now, he can slowly study the information given by Foster Company while eating a pile of cockroaches.
