A Vaccine Plan, A Change of Perspective / Setting Out, Landing Off Target

Honestly, judging by how lovey-dovey Lupin and Tonks are, Sirius really thought he had already confessed everything.

But judging from Lupin's worried and anxious appearance, the situation seems a bit pessimistic.

"I... I haven't said it yet..."

"Still haven't said anything? Remus, what is it that you haven't said yet?" Tonks glanced around, then fixed his gaze on Lupin's eyes, his expression turning icy.

"All these people in the room... Harry and the others know about it, right? Madam Pomfrey knows too, and I'm the only one who doesn't?!"

"That... Tonks, Lupin, he actually..."

"Let him tell me himself!!" Hermione tried to persuade him, but Tonks interrupted her with a sharp scream, her eyes never leaving Lupin. "Remus, what are you hiding from me?!"

"I..." Lupin was speechless for a moment.

He could actually sense the vague feelings between himself and Tonks, but that was precisely why he dared not tell her the truth.

Tonks is youthful and beautiful, practically universally loved, but he himself is old and ugly. The two of them are simply...

If she were to find out that he is a Werewolf, then perhaps even this last remaining 'friendship and care' would be completely lost...

"Looks like everything's completely alright," Harry suddenly pointed to the moon outside the window, "Uncle Lupin, congratulations!"

"Congratulations... to me?!"

Lupin, who was being questioned, was suddenly shocked. He stared wide-eyed at the full moon in the sky, then looked down at his hands in disbelief, his whole body trembling with excitement.

"Nothing has changed... nothing has really changed! I... I really haven't changed!!"

A strange excitement seemed to rise in his mind, as if trying to awaken the wildness that had been tamed within him, but his will was completely able to suppress it, and there was no change in his body at all!

At this moment, Lupin could no longer contain his joy.

"Haha! That's great! Padfoot, did you see that? I didn't transform! I'll never be affected by that curse again! I'm completely cured!!"

"Yes... I see! You're all better, Moony! Really, if James and Lily could too... Anyway, this is just so great!"

Seeing Lupin still in human form under the full moon, Sirius's eyes also welled up with tears. The two grown men, unable to contain their emotions, embraced each other and wept bitterly.

"Oh no... what's going on? What's wrong with Lupin? Can someone tell me?!"

Even though he was the one who was upset about being kept in the dark, Lupin and Sirius were both crying their eyes out, while Tonks, who was a bit slow to react, was worried but still couldn't figure out what had happened.

"Hey, is your brain really as dense as the Detective Society's badge?" Harry sighed helplessly. "Tonks, have you heard that Lucius Malfoy once led people from the Ministry of Magic to cause trouble at Hogwarts, and they even framed Uncle Lupin for something?"

"The charge... could it be?!" Tonks suddenly looked up at the moon in the sky, then looked closely at Lupin, and was completely stunned.

"So, Remus is a..."

"I can only say that it used to be, because I've completely cured him..."

"Thank you!!"

Harry wanted to explain Lupin's situation in detail, but Tonks didn't bother to listen to Harry's explanation and simply gave him a big bear hug!

"Wait... isn't that a bit off?" Harry was taken aback. "Shouldn't you be surprised and then ask me how I cured him?"

"Those things aren't important, I just need to know he's better! As for how he was cured, are you sure I can understand?"

"Uh... okay~" Harry scratched his head helplessly, realizing that was indeed the case.

This young woman, Tonks, is seven years older than me, but her intelligence and personality are definitely at the level of a seven-year-old.

However... her passionate and decisive nature is truly admirable.

While Harry was lost in thought, Tonks had already dragged Sirius away from Lupin and started shooing everyone else out of the room.

"All of you get out! I need to speak with Remus alone!!"

Chapter 515 Vaccine Concept, Shifting Mindset

BOOM!!

The door behind them slammed shut with a loud bang, startling the four of them into exchanging bewildered glances.

"This... Tonks wouldn't harm Lupin, would she?" Hermione looked back worriedly. "Lupin is still very weak."

"A fight? Heh heh, I'm afraid this girl's not just going to start a fight~" Sirius suddenly grinned mischievously. "I think we should stay away now, so we don't get splattered with blood later."

"Godfather, please, can you be a decent human being? Why do you have to say things like this in front of Hermione?" Harry sighed, rubbing his forehead. "Besides, Tonks is your niece, after all. Making jokes about her like that is just too disrespectful to your elders!"

"You said it yourself, it's just a joke, isn't it?" Sirius curled his lip nonchalantly, his smile undiminished. "Think about it, your best brother suddenly becomes a junior. From now on, when Moony sees me, won't he always be incredibly respectful to me?"

"Ah... what you said actually makes a lot of sense~"

Harry chuckled, indicating that he was speechless.

Sirius's idea is actually a bit like Harry's college roommates being father and son in his previous life... well, it's exactly the same as that shameless old man's perverse sense of humor.

However, the contrast between Sirius and Lupin is quite striking.

Although they are both middle-aged men over thirty, Sirius, after a period of recuperation, has now been reborn from the ashes of Azkaban's torment. He now looks like a model with a handsome young gentleman, and people would believe he is under thirty.

On the other hand, Lupin, who is even a few months younger than Sirius, looks like he's almost forty due to the pressures of life and the torment of Feral Wolf Syndrome. He has only recently begun to recover his health.

Harry felt that the Feral Wolf Syndrome was only one aspect of the problem; the real issue was that Lupin was too attached to things and couldn't let go of what he had taken in.

Both of them carried heavy pasts, but Sirius had clearly let go more completely. He had now found joy in his father-son/friend relationship with Harry, and was becoming increasingly like the carefree and optimistic Black of his student days.

But Lupin still seemed somewhat depressed, unable to let go of many things.

But he should gradually get better... what if he really becomes Sirius's nephew-in-law?

"I just want to know, Harry, how did you manage to do something like this?!" Unlike Sirius, who was joking and watching the spectacle, the knowledgeable Madam Pomfrey was completely astonished. "Feral Wolf Syndrome... that's incurable! I never imagined Lupin could actually be cured!!"

"Well... it's nothing really. We just used some modern medical assistance to help Lupin create the serum," Harry explained casually, without going into too much detail.

"Modern medicine... is it just those Muggle doctors who operate and give injections? That's unbelievable! How can they be so capable?!"

See, that's why Harry doesn't want to go into details.

Madam Pomfrey was completely shocked, because she had never imagined that those Muggle doctors, whom she considered stupid and incompetent, and their medical practices that involved surgery at the drop of a hat, could solve a problem that had plagued the Wizarding World for thousands of years!

And then there's the serum Harry mentioned. If it could be used in large quantities, wouldn't all Werewolf have a chance to recover?

"Harry, you have to publish this finding, you have to apply for certification at St Mungo's's, you know that?" Madam Pomfrey said to Harry excitedly. "Being able to completely solve the problem of all Werewolf, you will definitely become like Damocles Belby... no, once your findings are made public, you will definitely become an apothecary and healer who surpasses him!!"

"Let's talk about that later. I don't really need that kind of fame right now." Harry politely declined Madam Pomfrey's enthusiastic offer. "Besides, completely solving the Werewolf problem can't be done with just a mere serum."

As a doctor, Harry knew all too well that treatment alone was far from enough to completely eradicate any infectious epidemic; a nationwide epidemic prevention process was essential.

A striking example is that smallpox has been eradicated in the ordinary world, but in the Wizarding World, Dragon Pox remains a deadly infectious disease that strikes fear into the hearts of many... Isn't the biggest difference simply because the Wizarding World lacks the concept of vaccines?

Feral Wolf Syndrome faces the same problem: how many Werewolf can be cured using only the serum Harry created with Lucius Malfoy's blood?

And would Werewolf really accept the injection willingly?

Even if it were voluntary, could Harry really expect these penniless guys to give him enough compensation?

Just think of Damocles Belby, the apothecary who originally wanted to make a lot of money with his Wolfsbane Potion, but in the end he only had fame but no profit.

He thought that by developing the Wolfsbane Potion, he could improve the Werewolf's problems, but this stuff was essentially a targeted drug that he had to take until he died... and it was even worse than a targeted drug.

The Wolfsbane Potion only affects Werewolf's self-awareness during transformation; for most Werewolf, it's practically unnecessary. But try asking a cancer patient to stop taking targeted therapy?

Werewolf choosing to take potions might be a more rational way to survive the transformation, but if they spend too much time on them, their houses will be gone, their families will be ruined, and how will they survive?

But if you don't eat... well, then you're out of luck. You either muddle through the transformation or just run out and bite people.

So why are the wizards unwilling to help the Werewolf?

Because it's both dangerous and doesn't pay well.

Given the current situation, Harry's hopes of making money from the serum are basically dashed. If he wants both fame and fortune, and to completely eradicate the Feral Wolf Virus, he'll need to conduct further research...

That, of course, is the vaccine.

Telling all Werewolf that paying a little money for two injections of serum can completely cure their Feral Wolf Syndrome is unlikely to be very effective.

But if Harry could mass-produce vaccines and prove to all wizards that following medical advice and getting vaccinated could prevent one from turning into Werewolf, what do you think the results would be?

Especially since Harry has the backing of Hogwarts, the only magic school in Britain, if they simply add a medical check-up to the new student enrollment process, wouldn't all those wizarding parents be scrambling to get their kids lined up for injections?

Even they themselves might shamelessly try to get vaccinated.

So you see, by simply changing your mindset slightly, you can often achieve better results than you expected.

But wizards... their weakest point is changing their way of thinking.

"Everyone, go and rest. Get some rest tonight, and we'll set off tomorrow!"

Now that Lupin has been confirmed fully recovered, Sirius can finally breathe a sigh of relief. Next, it's time to retrieve Regulus's body...

"Tonks, can you call an owl for me?"

Meanwhile, Lupin, who was resting in his room at that moment, took advantage of the darkness to send a letter to the school, which was on holiday...

Chapter 516 Departure, Landing Point Deviation

The day after the full moon, the group saw Madam Pomfrey off at the mansion and received Kreacher, who had been ordered to come. However, just as they were about to set off, they discovered that there was another 'uninvited guest' at the gate.

"Headmaster?" Harry raised an eyebrow slightly upon seeing this; Albus Dumbledore's timing was impeccable.

Dumbledore, who suddenly appeared here, was wearing a travel robe that was easy to move in, and even his hat was a simple style. This was obviously not his attire for a casual stroll.

In addition, his long nose was more crooked and disproportionate than before; Aberforth Dumbledore's earlier punch had clearly had a remarkable effect.

"Are you all getting ready to depart? Looks like I'm on time." Dumbledore greeted the group, then began to admire the entire mansion. "Not bad... Harry, this is truly a magnificent house. It's large and luxurious. No wonder the Accidental Magic Reversal Squad had to deploy ten Obliviator to finally quell the effects of that night."

"Then I've really caused them trouble," Harry smiled nonchalantly, then asked with feigned curiosity, "Headmaster, what brings you here?"

"I invited Headmaster Dumbledore," Lupin said, emerging from the room with Tonks' support. "I was supposed to go with you to find Regulus, but my health simply won't allow it, so I had to ask Headmaster Dumbledore for help. Padfoot, Harry ... I truly hope everything goes well for you."

Last night, Lupin sent a letter to Dumbledore, which is why Dumbledore 'coincidentally' arrived just as Harry and the others left.

"Remus ...seeing you like this now, I'm truly happy for you! Harry did even better than me; he not only made up for my previous mistakes but also completely broke the curse that plagued you."

Dumbledore's voice trembled slightly as he quickly stepped forward and embraced Lupin's shoulders, carefully examining the man's weathered face, as if to confirm whether Lupin had truly escaped the nightmare last night.

He was genuinely happy for Lupin, which perhaps explains why Lupin insisted on having Dumbledore accompany Harry and the others to that cave.

Because Dumbledore a second life to Lupin, when Lupin was unable to accompany him due to health reasons, Dumbledore was the most trusted insurance in his subconscious.

Lupin always believed that Dumbledore could protect Harry and the others who were so important to him, just as he had protected him during their school days!

"Alright then, let's go together. Kreacher, take us to that cave." Harry shrugged nonchalantly and beckoned everyone to gather around Kreacher.

"Yes... yes!!" Kreacher responded excitedly, hurriedly leading his men to Apparition.

As everyone was about to disappear from the spot, Harry and Dumbledore exchanged a glance, their eyes seemingly containing a deeper meaning...

Snap!!

With a series of ear-piercing 'pop' sounds, like chestnuts bursting open, the group suddenly appeared on an unknown beach.

"Ugh..." Hermione's legs went weak and she collapsed to the ground as soon as she stepped onto solid ground. She then began to gag violently, as if she had just experienced a dizzying, weightless sensation.

Harry is also feeling very uncomfortable right now. He realized something was wrong when he first noticed the pressure on his body from all directions. Later, he felt like he was being torn into noodles and squeezed out of a tube.

Moreover, their current location is clearly wrong. The salty sea breeze is blowing around them, and the sound of crashing waves is echoing in their ears... This is by the sea, not in the cave that Harry expected!

Most importantly, Kreacher is nowhere to be found!

By the way, that 'pop pop' sound just now, that's a sound only a wizard can make when they Apparition!

"Headmaster, why did you intercept Kreacher's Apparition?" While tending to the extremely unwell Hermione, Harry frowned at Dumbledore, clearly waiting for his explanation.

"I only wanted to ensure everyone's safety, so I adjusted the landing point to outside the cave," Dumbledore explained apologetically. "However, Kreacher was indeed an accident; I didn't expect him to ignore my attempts to stop him."

"Of course, in fact, I do want to verify my conjecture here." Dumbledore pointed to a cliff behind them. "Harry, do you see the halfway point of that cliff? Tom ... that is, Voldemort, when he was young, he took some children from the orphanage there."

"An orphanage?" Sirius looked puzzled.

"Yes, Wool's Orphanage," Dumbledore nodded. "That's where Tom Riddle grew up. I've been suspecting that Tom might have hidden one of the Horcrux here while I was investigating the Horcrux, and now it seems I was right."

"And I'm also very curious about why Tom turned out the way he did... He probably already showed those tendencies when he was a child, using underage magic to bring the children he bullied here, placing them on terrifying cliff tops to enjoy the thrill of frightening them..."

"Headmaster, I have absolutely no interest in Voldemort's childhood." Just as Dumbledore was expressing his sentimentality, Harry interrupted him indifferently, "Instead of analyzing Voldemort's past, we should be heading into the cave immediately. Kreacher all alone in there right now! Besides, instead of dwelling on his time in the orphanage, you'd be better off reflecting on his school years."

"When he was in school... Harry, do you think there was something wrong with Hogwarts' education of Tom Riddle?" Dumbledore's tone lowered, and whenever he encountered this kind of ideological conflict with Harry, his mood would involuntarily begin to feel depressed.
