On the afternoon of March 10, Felix showed up with a small piece of paper with an address. In front of him was a beautiful little house. He stood on the steps and looked around. The surroundings were very empty. Felix smelled a faint fragrance of flowers. He guessed that there must be a beautiful garden behind the house.

Felix knocked on the door.

A man with golden hair and a big belly opened the door and looked at Felix with a puzzled look.

"Hello, who are you looking for?" the man asked. He was suddenly stunned. "Oh, you are Mr. Hepp, Felix Hepp?" After getting a positive answer, he led Felix into the house and came to the living room.

"Sorry, I didn't recognize you! I have to say that compared with your great fame, you seem too low-key. I have only seen you a few times in the newspaper... Yes, Dora told me that you would come, but I didn't expect you to come two hours earlier. Domida? There are guests coming."

The man shouted to a corridor in the living room, then he looked at Felix and extended his hand in a friendly manner.

"I'm Ted Tonks, Dora's father."

"Hello, Mr. Tonks, Felix Hepp..." Felix shook hands, looked around the cleaning tools in the living room, and said with a hint of embarrassment: "I think I may have remembered the time wrong..."

"Oh, never mind," Mr. Tonks said, picking up the Mrs. Skoll brand all-purpose magic stain remover at his feet and placing it next to the potted plant on the table, "Dora and the others won't arrive until seven in the evening. She is an Auror and has a heavy responsibility."

"Is this aphid?" Felix asked, staring at the potted plant. This is a perennial evergreen herb. Because the berries look like spider eggs and the underground rhizomes exposed to the soil are similar to spiders, it is also called "spider eggs".

"Yes, it--" Mr. Tonks' words were interrupted by footsteps. Felix and Mr. Tonks turned around at the same time. A strange woman appeared at the door of the living room. She looked a bit like Bellatrix Black, but her hair was soft light brown instead of black, and her eyes were bigger and kinder.

There is no doubt that this woman is Andromeda Tonks, who comes from the Black family and is a sister of Bellatrix Lestrange and Narcissa Malfoy, but she is now Tonks' mother.

Mrs. Tonks smiled at Felix, and then exchanged a look with Mr. Tonks.

"This is Mr. Felix Hepp." Mr. Tonks introduced.

"Oh, hello, Mr. Hepp, Nymphadora mentioned several times..." Mrs. Tonks said, "I was just cooking in the kitchen. But you came early enough."

So Felix used the excuse of "wrongly remembering the time" to prevaricate.

Mrs. Tonks reluctantly nodded. "Please take a seat." She said, "I'll go prepare some tea - Ted, Ted, come and help me." "Oh, oh, okay." Mr. Tonks turned to look at Felix and muttered, "I remember that I did collect some tea... I'll be right back! You can read the newspaper first, it's on the table." Felix nodded slightly

, watched them disappear into the corridor, leaned over to pick up the newspaper beside him, and pricked up his ears to listen. As expected, a small dispute came from a corner of the room - perhaps the kitchen or the bedroom.

"... I know the reason... Act as a lobbyist, don't mention the war to me, it's over... I warn you, Ted Tonks, if you dare to promise rashly..."

Felix calmly shook the newspaper. The news worth paying attention to was that the Minister of Magic, Ms. Bones, returned from the headquarters of the International Confederation of Wizards, and participated in several important meetings with representatives from all over the world.

The specific details of the meeting have not yet been announced.

The newspaper made some speculations, believing that the biggest possibility is related to the law of exclusive wands, which may become a reality in a few years. There was also a photo hanging on the newspaper, with a dozen stiff figures standing together, and the new chairman Babajide Akinbade looked tired.

A few minutes later, Mr. Tonks came back dejected, and his expression was somewhat similar to Babajide in the newspaper. He bumped into the table when he walked over, and couldn't help but screaming in pain. The potted plant shook, and he hurried to hold it.

"A few leaves fell off." He looked at it and whispered, sitting down, "So-uh-"

"Oh, Mr. Tonks." Felix put down the newspaper and said, "I just remembered something at the last minute." As he spoke, he stretched out his hand, and two fallen leaves in the potted plant turned into two beautiful invitations.

"I'm planning to hold a small press conference this weekend, the kind of party. If you have nothing to do, you can go and take a look."

Mr. Tonks took the invitation and muttered softly: "Press conference? That should be at the headquarters of the 'Future World' company? I think... well, there may be some problems, it's not very convenient." His voice lowered, and he began to concentrate on reading the introduction on it.

After a while, he raised his head.

"Mr. Hep, I don't quite understand - 'witness with all the guests the birth of a new type of treatment method, and discuss the causes of some diseases that plague wizards'..." He read out a paragraph, and then asked, "It sounds like a serious academic report."

"Almost. I have invited many pharmacists and therapists who are quite famous in their respective fields, and even some alchemists." Felix smiled and said, "But it's essentially a party, because I don't expect these people to understand what I'm saying in a short time. The press conference will last for a week. Of course, you are attending the dinner on the first day, and the main purpose is socializing."

"By the way, I overheard Tonks mention that you know something about Muggle medicine?"

"Ah, you're talking about this," Mr. Tonks said happily, "My uncle is a surgeon. When I was a kid, I often went to his house to play," he said excitedly, "There is a study in his house with various surgical models. I was really scared at that time..."

Felix listened with a smile and said, "That's a coincidence. The new treatment method I mentioned may introduce the Muggle concept of surgery. What surprised me is that wizards seem to be quite reluctant to operate on themselves."

Mr. Tonks slapped his thigh excitedly.

"Oh, I thought so too! When I was in school, I always thought that Madam Pomfrey could only deal with minor injuries and illnesses. It was not until I went to St. Mungo's several times after graduation that I realized that wizards did not have this concept. Of course, I think it's because magic is too convenient and there is no need..."

The wizard from a Muggle family looked like he had found a common topic.

"Anatomy," Felix said softly, "This subject has not been applied in the field of treatment, because for wizards, the problems that trouble Muggles can be solved with a simple magic... On the contrary, there are some applications in the field of potions. They will conduct detailed drawings and potion tests when researching new potion materials."

"But is this really useful?" Mr. Tonks asked curiously, "I mean, in treatment? I have talked about this topic with some wizards, and they think Muggle doctors are a group of..."

"A madman who cuts people open." Felix nodded and said, "I personally think it's a problem of positioning. Given the differences between the two societies, surgical knowledge that is very important to ordinary people may only play the role of supplementing the wizards' treatment methods. But having and not having are different concepts."

"For example-"

"Dragon pox, this disease is only spread among wizards and is fatal. The early symptoms are green and purple rashes between the toes and sparks from the nostrils when sneezing. If treated in time, it can generally be cured, leaving only some ugly scars or bruises on the skin."

Mr. Tonks nodded with a little confusion.

"I remember a Minister of Magic who died of dragon pox?"

"Edrich Diggory, he worked while sick and eventually died in the office. This disease is more common among the elderly, and it is more hidden when it occurs, so it is more dangerous. Some healers believe that dragon pox was originally related to the Peruvian Venomous Dragon."

Felix said preparedly.

"The teeth of the Peruvian Venomous Dragon are highly poisonous." Mr. Tonks reminded.

"For ordinary wizards, that's true." Felix explained, "So it could be diluted toxins, or saliva, or parasites or pathogens that have not yet been discovered on them... In short, there is no conclusion yet." Then he changed the subject, "But I once found a patient with advanced dragon pox in St. Mungo's. Out of curiosity, I checked his physical condition. Unfortunately, he was incurable at the time. He was bruised all over - of course, this is just a minor problem. The truly fatal thing is that his magic power has also become a mess, and some unknown mutation has occurred, which makes all existing treatments ineffective."

"That person must be in great pain." Mr. Tonks murmured.

"I suspect that patients with advanced dragon pox have many hidden wounds in their bodies. In fact, the bodies of those wizards may already be riddled with holes." Felix said slowly.

"Hidden wounds?"

"I found a similar example. The body structure of magical animals is different from that of wizards. Their magical abilities are more dependent on the special lines in their bodies. These lines are integrated with the flesh and blood, and are difficult to detect, but they are channels for the flow of magic, or...magic circuits. Therefore, magical animals do not need to learn to acquire the ability to cast spells like young wizards."

"So that's how it is." Mr. Tonks suddenly realized.

"...But this kind of disease is undoubtedly harmful to wizards. Some lines are messy and the result is life-threatening, such as dragon pox; some have reached a strange coexistence with wizards, which has an impact but is not fatal, such as werewolves."

Mr. Tonks took a breath.

There was a scream from the door. It was Mrs. Tonks, and the teapot in her hand fell down. Felix waved his hand and let the teapot fall on the seat.

"Oh, thank you, Mr. Hep." Mrs. Tonks said in an unnatural tone. She listened at the door for a long time. She walked over carefully and put the cup down. "So, can the werewolf problem be cured?"

"Good question. I discovered and isolated the 'pathological patterns' that affect werewolves. Combined with what I said before, there is actually great hope for a breakthrough. Of course, I'm not an expert in this area, so there is a party this weekend."

"It sounds very convincing, Mr. Hep, I can't find any loopholes." After a while, Mrs. Tonks said in a flat tone, "But you can't deny that all this is just theory, a castle in the air... Even if the theory is correct, it will take many years to become a reality."

Even though the conversation was close to the core and both parties knew it, neither of them mentioned the name.

"I agree, Mrs. Tonks."

Felix said in a slightly happy tone, as if in his opinion, everything was going well.

"In the field of treatment, especially in the area related to potions, I may not be able to help, nor can I make any groundbreaking achievements. But don't forget, I am an expert in ancient runes, and I always think about problems from the perspective of ancient runes. Fortunately, some results have been achieved... Although it is extremely difficult and not suitable for large-scale promotion, it can still be used on one or two people to solve some difficult problems. Do you want to listen?"

Mrs. Tonks pursed her lips, and after a long time, she said coldly: "You are really a good lobbyist, Mr. Hep - I am happy to listen."

Half an hour later, Felix, accompanied by Mr. Tonks, visited the rooms in the house.

"These are Dora's toys when she was a child." Mr. Tonks pointed to a row of plush dolls on the shelf and said: "Originally there were quite a few human-shaped dolls, but when we realized that she deliberately imitated the expressions of dolls, we replaced them with small animals, mostly rabbits and bears. But her aesthetics still deviated a little. She obviously prefers violet or pink hair instead of her own gray-brown." He said a little hurt.

Felix understood clearly that Tonks's original hair color obviously inherited the characteristics of both parents - a balance between light brown and gold, but she herself was obviously not satisfied.

They came to the garden in the courtyard.

Mr. Tonks introduced the various plants diligently, "You have seen the pink, and the purple is here - we planted a lot of violets, all kinds of them. Do you see the depression in the middle? It doesn't look good now, it's a bit ugly, but when it rains, it will be filled with water. We will choose to plant some aquatic plants, such as water hyacinths. Oh my god, it's purple again, I realized..."

At this time, there was a commotion in the house behind them.

"Someone is coming." Mr. Tonks said puzzledly.

"Is it Tonks and them?" Felix asked.

"I don't think so. It's still early. Dora will get off work for more than an hour... It's strange." Mr. Tonks said, walking towards the house. They heard voices faintly.

Felix followed behind, rolling his eyes, and he roughly guessed who the people were.

"Hello, Sirius." As soon as they entered the door, they heard Mrs. Tonks's somewhat annoyed voice, "There's no need to send so many things. The living room can't hold them all."

Then they heard a hearty laugh.

"Oh - you're welcome, my dear cousin. And I know Remus so well, I can't believe he got there before me..." Mr. Tonks suddenly slowed down, even becoming a little creepy. He quietly opened a gap from the back door to make Sirius's overly enthusiastic voice clearer.

"...Cousin, speaking of Remus, he is one of the few people I admire. He is brave and kind, and always puts others first. I swear, the number of people he has taken care of over the years is definitely beyond imagination, even though he himself is poor. Well, I mean, he used to be, and now he is quite rich. He can definitely buy a house in Diagon Alley..."

Felix looked over Mr. Tonks' shoulder and saw Sirius talking with a smile. He was dressed very formally today, wearing a neat suit, with a green handkerchief with silver thread in the chest pocket, and the Black family's coat of arms embroidered on the corner of the handkerchief. He

looked like a best man.

But Felix was not sure whether this dress had the opposite effect, or whether it was because of Sirius's increasingly explicit hints. Because Mrs. Tonks's face became more and more gloomy, and her fingers tightly grasped the soup spoon, as if she was ready to raise it and hit her cousin on the head at any time.

Felix wanted to pretend that he didn't see it, so as to avenge Sirius's frame-up, but considering the stability of the Future World Company in the next few decades, he still cleared his throat.

Sirius stopped talking and turned around in surprise.

"Felix? Why did you come so early?"

"What else could it be?" Mrs. Tonks said sternly, teasingly, "Of course it's the same purpose as yours."

...

When Tonks, feeling uneasy, came back with Lupin, who looked reserved, more than an hour later, they were surprised to find that they were treated not warmly, but definitely not coldly. Even when Sirius deliberately mentioned his childhood memories, Mrs. Tonks smiled. After

dinner, they said goodbye and left. Lupin walked out of Tonks's house with light steps, his face half incredulous and half grateful for surviving a disaster.

Before parting, Sirius patted his shoulder. In an instant, Lupin seemed to understand something, and his eyes were wet. He hugged Sirius tightly, and let go for a long time, then turned to Felix.

"Felix, this birthday is my-"

"Work hard." Felix said, ruining the atmosphere. Sirius rolled his eyes.
