The Wolfbane Serum Is Finally Successfully Developed / Werewolves Who Refuse to Repent Aren't Worth Saving

Harry did not choose to treat the Mulciber Jr., who was quickly dying. Instead, he used his ability to control water to accelerate Mursab's blood circulation, so as to ensure that the Feral Wolf Virus could fully integrate into his body.

After that, when the time was almost up, Harry hypnotized Mulciber Jr. again, making him believe it was a full moon night, while simultaneously injecting him with a sufficient dose of adrenaline.

And so, another silly wolf with a long, hairy face appeared in the safe.

"Very good~" Harry nodded in satisfaction as he looked at the four Werewolf lying in front of him.

At this point, he had completed all his research on actively inducing Werewolf to transform through external forces.

This also means that when Harry faces Werewolf, he doesn't need to consider whether it's a full moon or not; he can freely control or cancel the werewolf's transformation!

Of course, this was not the final result he had hoped for, because these alone would not help Lupin.

The following experiments are the real highlight.

He can finally begin producing the serum!

Chapter 466 The Feral Wolf Serum has finally been successfully prepared.

After completing the Werewolf transformation experiment, Harry ignored the four barking canines and went straight to the experimental table inside the Magical Combination Chest.

There, he had already placed a special, round instrument that looked somewhat like a rotor.

That was a magical centrifuge that Harry created using the Sorcerer's Stone. Because of the combined effects of wind and water elements, this machine could basically simulate the speed and low temperature requirements of a medical centrifuge.

Centrifugation to extract serum was a step Harry valued highly. Although blood could be separated into layers simply by standing at low temperatures, the serum produced that way would never meet Harry's requirements in terms of either quantity or quality.

The research on the Feral Wolf Virus had taken about six months, Harry didn't want to have to keep reworking it just because the serum was of poor quality.

So, with the help of Nicolas Flamel, he decisively built this high-quality machine.

Harry drew several test tubes of Lucius Malfoy's blood. After such a long period of cultivation, it was time to verify whether his serum contained immunoglobulins that could fight the Feral Wolf Virus.

Place the blood sample in a centrifuge, set the speed to 4000 rpm, and the time to five minutes...

Soon, Harry saw the successfully separated blood plasma in the centrifuge tube and carefully collected the pale yellow serum from the top with a pipette.

Finally, I can try the injection...

The process of injecting serum is actually quite challenging, since the dosage of something like immunoglobulin needs to be determined based on body weight.

However, Harry had no idea about its effects, and since he was going to use these Werewolf for animal experiments anyway, he decided to try it according to the instructions for the Rabies Virus serum injection... After all, they were canines, so hopefully it would work.

So, based on a dosage ratio of 40 IU per kilogram of body weight, and after roughly estimating the protein content in the serum, Harry successfully prepared three simplified versions of immunoglobulin injections, which he then injected into the buttocks of Greyback, Mulciber Jr., and another Werewolf, respectively.

In order to ensure the success rate of the drug experiment, Harry used a larger dose than the theoretical value. For intramuscular injection, injecting into the buttocks would be relatively safer.

Poor Mulciber Jr., from the moment he was bitten to his transformation, Harry didn't give him even a moment's respite, subjecting him to both physical and mental trauma and the excruciating pain of a ripped open bottom.

After injecting the three Werewolf with the serum, Harry immediately began to closely monitor their condition, but after waiting for several hours, an unexpected incident occurred.

Fenrir Greyback is dead.

Harry administered the injection while the three test subjects were in their transformed state, believing this would allow for the fastest possible reaction. However, just as Greyback's body spontaneously transformed back into a Werewolf, he suddenly underwent a mutation.

Greyback seemed to have suffered a great shock; he suddenly began to writhe violently on the dissection table, and finally even managed to break free from the restraints Harry had placed on him!

After a agonizing roar, he only had time to glare fiercely at Harry with his half-human, half-wolf eyes before he completely lost all life, his eyes remaining open until his death.

His gaze remained fixed on Harry until his dying breath, as if trying to imprint Harry's image into his pupils. When those venomous eyes stared at him, Harry even felt as if he were under some kind of curse.

It seemed to be more than just Fenrir Greyback's resentment; it was more like the 'Feral Wolf Virus' that had plagued him for decades, cursing Harry, the executioner who was about to wipe out the Werewolf race!

However, Harry quickly put his fear aside.

He had seen countless corpses with their eyes wide open in death, so he wasn't afraid of Greyback's one.

Besides, even if it were a curse, so what? It's just Werewolf. Harry isn't afraid of the living, so why would he be afraid of death?

So, after composing himself, Harry began to focus intently on the specific effects of the Feral Wolf Serum.

In retrospect, the immunoglobulin he prepared, apart from being potent, seems to have no serious drawbacks and is definitely effective.

He watched almost as Greyback's corpse completely transformed into a human, with no trace of Werewolf remaining.

As for the other two test subjects, Mulciber Jr. also died soon after, but he didn't die during the transformation process; he died after fully reverting to human form.

This also led Harry to discover a major side effect of the Feral Wolf Serum.

Once injected into the human body, it immediately produces an extremely strong antigen-antibody reaction. This can be seen from Greyback's performance. In addition to enduring extreme physical pain, the Werewolf seems to also suffer a great mental shock.

This pain intensifies with the years one becomes Werewolf, so Greyback suffered the most of the three test subjects, eventually exceeding his body's limits and leading to his death.

As for Mulciber Jr.'s death, it was because after the Feral Wolf Virus in his body was eliminated, the Werewolf's body would become extremely weak. His body had already endured a lot of burdens, which is why he was unlucky enough to fail to complete the weakened period after the reaction.

Therefore, if the time spent as Werewolf is not very long and the patient's physical condition was generally good before the serum injection, there is a high probability that death will not occur.

The only remaining Werewolf is in pretty good condition. Apart from being weak all over and having difficulty even moving his fingers, he has basically no other problems.

However, considering that his body was already exhausted, Harry stopped torturing him and instead injected the last Werewolf with the serum.

This time, he administered the injection after the Werewolf had reverted to human form.

Harry wanted to determine whether injecting the serum in human form would have the same effect; he was also considering whether the antigen-antibody reaction would be less severe in this state, which might further ensure the safety of the injection.

Lupin had been Werewolf for almost thirty years, even longer than the two other test subjects besides Greyback. Once he received the injection, the pain he would have to endure would definitely be considerable.

Therefore, Harry needs to be extra careful as he gets closer to the final stage, because one slip could really ruin everything.

So, just relax and wait for the full moon to arrive in a few days.

Harry was looking forward to this full moon because it would give him the opportunity to test the final natural effects of the Feral Wolf Serum and determine the best injection regimen for Lupin.

The wolf girl is also looking forward to the next full moon, because...

She's been holding that leaf in her mouth so much that she's practically washing her face with tears (and saliva) every day.

Chapter 467 Unrepentant Werewolf are not worth saving.

"Very good!"

On the night of the full moon, near the end of May, as a bright full moon hung high in the night sky, the wolf girl, who had worked hard for a month, finally let out a joyful sigh.

She was so happy because she had finally kept the Mandrake leaf in her mouth for the full month, and no longer had to awkwardly be fed and watered by Harry every day, or drool constantly.

Furthermore, Harry had thoughtfully prepared the Potions ingredients she needed for her transformation. All she had to do was put the Mandrake leaves into a crystal vial containing her own saliva and then hand it over to Harry to handle.

Taking advantage of the perfect moonlight, Harry buried the Potions, after adding all the necessary ingredients, in the Forbidden Forest. All that was left was to wait for the storm to come.

Of course, there's still one step in between, and the wolf girl is still a little apprehensive about it.

As a descendant of Werewolf, the wolf girl has no wand, and she's unsure if Animagus spells will work for her.

"Your goal is to become human again, so normal Animagus spells are definitely out of the question. As for the wand, you're actually Fantastic Beasts in your current state, so you don't need one."

Fortunately, Harry had thought of these problems long ago, and he also taught the wolf girl a special spell.

"Compel Homo morph humagus... what does this spell mean?" After Harry repeated it, the wolf girl asked, somewhat confused.

"It's basically me forcing myself to become human," Harry explained casually. "From now on, recite it once at sunrise and once at sunset every day. Make sure your pronunciation is accurate and you do it enough times. That way, when the storm comes, you should be able to successfully Transfiguration."

"Should?" The wolf girl hesitated for a moment upon hearing this. "Is there still a possibility of failure?"

"Of course," Harry replied with an air of utter disbelief. "Even humans have a high chance of failing the first time they try to learn Animagus, let alone this spell which I just tried to deduce. I had absolutely no prior experience with it. Why do you think it will definitely work?"

"Uh..." The wolf girl was speechless when she saw Harry's self-righteous attitude.

Okay, so this guy is still using himself as a guinea pig.

However, she didn't have much of an opinion about it. As she said before, Harry was her greatest hope, and she would do whatever Harry asked her to do.

"By the way, are you red-green colorblind?" Harry suddenly asked on the way back to the castle from the Forbidden Forest.

"I... I'm not..." The wolf girl's voice suddenly became extremely low, clearly indicating that this was a question that deeply touched her.

Many people believe that the descendants of Werewolf are a pack of real wolves, but the wolf girls are indeed very different from wolves.

For example, it possesses intelligence completely equivalent to that of humans, rationality that suppresses animalistic instincts and a sense of shame, and eyes that are essentially identical to those of humans.

The wolf girl wasn't red-green colorblind; the world she saw was just as colorful.

"Don't get me wrong, I just want to increase your chances of success with your transformations. Here, take this; you can look at it whenever you have free time."

Seeing that the wolf girl seemed a little depressed, Harry casually offered an explanation, then tossed her a... swimsuit magazine.

"Huh... why did you give me this?" The unsuspecting wolf girl flipped through a few pages with her mouth, only to be so shocked that she almost bit the whole magazine through.

The paintings there, those women... they're so shameless!

"I'm afraid you can't imagine what you'll look like when you transform," Harry said matter-of-factly. "What, do you expect me to provide you with a book about being completely naked?"

"I... I didn't mean that!" The wolf girl was immediately embarrassed when Harry asked her so bluntly.

Doesn't this guy realize that even though he can't walk upright, he's still a woman?

"Hehe, not the best."

Well... all I can say is that the wolf girl is definitely overthinking it.

After all, in Harry's eyes, their relationship was simply that of doctor and patient. Therefore, what Harry said to her was nothing more than proper medical advice, and everything he did was simply to increase her chances of successfully transforming.

So he absolutely did not secretly fold out pages from that swimsuit magazine or guide the wolf girl to transform into someone he thought would trigger his fetish... He just picked up that magazine casually and never even looked at it!

Before the full moon had faded, the two returned to Hogwarts Castle, and upon seeing the scene inside the Magical Combination Chest, Harry couldn't help but smile with satisfaction.

"We finally succeeded..."

Of the two Werewolf in the safe, only one transformed due to the full moon; that was the guy who survived the initial serum injection a couple of days ago.

As for the other Werewolf who received the vaccine under normal circumstances, and Lucius Malfoy, who is also Werewolf, they still retain their human appearance.

"But someone else has transformed, why are you so happy?" the wolf girl asked, puzzled.

"You'll see." Harry chuckled, then suddenly tossed the Death Eater Travers at the transformed Werewolf, letting the creature tear at Travers' body.

To the wolf girl's surprise, even though Travers was covered in wounds from being bitten, he showed no tendency to transform during the full moon; he simply lay on the ground covered in blood.

Moreover, Harry quickly healed his injuries with a spell, leaving no trace whatsoever, and Harry didn't use Dittany or silver powder at all.

"Now you know, after the serum injection, the virus in the Werewolf's body has actually been completely eliminated," Harry said confidently. "That means they will no longer be infectious!"

"But if that's the case, then why is he able to transform?"

"For Werewolf like him who have been bitten for a long time, the Feral Wolf Virus has completely integrated into their bodies. Therefore, even if the serum can kill the virus's toxicity, their ability to transform is still preserved."

Harry explained, giving the Werewolf a disdainful look. "During the full moon, the Werewolf's latent wildness begins to erupt, but after being injected with the serum, they can actually retain their rationality. Therefore, as long as they are willing to suppress their wildness—like that other guy— Werewolf won't transform."

"But this guy is just like Greyback who died before. He wants to transform and bite people every time there's a full moon, and even the Feral Wolf Serum can't stop him."

When Harry threw Travers out, he was absolutely certain that the Werewolf retained his own consciousness, yet the guy still chose to bite, which meant that he had chosen to fall into depravity from the bottom of his heart!

For other Werewolf tormented by their wild nature, the problem can be solved simply by casting Memory Charm on them, making them forget that they are Werewolf.

For example, Lucius Malfoy, who was used to cultivate the serum, could actually be considered a very ancient Werewolf, but Harry made him forget the fact that he had been bitten by Werewolf, so he was able to relatively easily suppress his restless wildness.

But Harry couldn't be bothered to waste his magic on such an unrepentant Werewolf!

So... he took out the Sword of Gryffindor!

Blood splattered as Harry, to the wolf girl's astonishment, pierced the Werewolf's heart with his sword!

Chapter 468 Lupin's needle was inserted through a combination of bluffing and deception.

Harry is a forensic pathologist, which is also considered a doctor. There's a saying in China: "Medicine can't cure all diseases."

Even the most effective medicine can only treat those who can be saved. The Feral Wolf Serum that Harry developed is the same; it ultimately cannot 'cure' all Werewolf.

Because some Werewolf are destined to be incurable.

Feral Wolf Serum can expel the virus from the body, but it can never rid the evil thoughts in the heart. For Werewolf who let their wildness run rampant and choose to fall no matter what, it is the only effective medicine...

There is only death!
