Chapter 43: New Medicine Completed

A shock ran through the wizarding world.

An urgent announcement was made by the Ministry of Magic. The entire wizarding world was astonished by its content.

Sirius Black, a mass murderer who had escaped from Azkaban, was actually innocent.

The real culprit was Peter Pettigrew, who was thought to have been killed.

It was Pettigrew who had betrayed the Potters and sold them to the Dark Lord, and Sirius Black had known this and cornered Pettigrew, but he had escaped and Sirius Black had been framed for betrayal and mass murder.

The details of how the truth came to light were not announced, but it was recognized in the world that it was due to the great wizard Albus Dumbledore because Sirius Black had been infiltrating Hogwarts.

Peter Pettigrew, who had been on the run, was also safely captured and sentenced to life imprisonment in Azkaban.

With this, Sirius Black was finally free and a large amount of compensation was to be paid by the Ministry of Magic.

The day after the shock of Sirius Black's innocence, another event that surprised the world occurred.

Peter Pettigrew, who had been imprisoned in Azkaban, escaped and disappeared.

This led to a question of responsibility for the Ministry of Magic, especially Minister Cornelius Fudge, but Fudge remained as Minister.

Regardless of such commotion in the world, Leonard Taylor had been working on improving the Wolfsbane Potion for several days.

With Lupin's help, a detailed analysis of werewolves was possible, so the previous Wolfsbane Potion has now become a completely different thing. The final adjustment is planned to be tested on Lupin.

"Phew. I guess this is it."

He decided to take a break after a while. As soon as he sat down on the sofa, tea was prepared. It was done by Ku in her maid form.

"Thank you, Ku."

He enjoyed the aroma and taste of tea. Ku's skills are improving day by day. She is growing in every field from cooking and other things to helping with potion making. The part where she can help with his work as a pet has already passed.

"Ku. After you finish your tea, let's go to the magic training ground. I want to see what your abilities are like now."

"Understood."

The magic training ground. This is a vast place expanded by space extension used for experiments with new magic and has high durability.

"Ku. Transform into combat form."

"Understood."

Ku's body grows one size larger. Her maid uniform also changes into black armor. He observes her state from corner to corner using his "eye", and actually touches it.

After that is the performance test.

The test results showed that the armor is made from dragon and basilisk scales transformed into shape and its durability exceeds them.

Even if hit by Avada Kedavra several times, it probably won't break through. Even if damage is inflicted, minor defects can be instantly restored with life water from body fluids.

After all, since single-celled organisms form one shape with a colony, there is no way to completely destroy it unless all trillions of cells are destroyed.

The change in her body is also beyond comparison with before. High-speed flight with dragon wings. Slashing with hair that has been hardened and is stretchable. From all over her body she can produce versatile tentacles, from the tip of which she can produce magic, dragon fire, basilisk poison. She can even change into basilisk eyes.

Honestly, even Leo who created her doesn't know if he can win even if he fights seriously with full ring power and doping with potions. As Leo, he is satisfied with this result.

"Hmm, wonderful... Ku. You're my greatest masterpiece. Is there anything you want? Feel free to say anything."

"Thank you very much, Master... Well, I have one request."

Ku takes a deep breath to calm herself down.

"Hug me and pat my head!"

Leo is surprised because it wasn't what he thought she would ask for.

"Is that really okay? Don't you want something more... like something you want? And why that?"

"Well... I've been praised before but I've never had such an act done to me. I'm not dissatisfied so far but I've been kind of longing for that kind of thing. I heard that dogs and cats get petted so I thought I'd like to be petted as a pet too."

(Hmm... Maybe it's because she's in girl form? I don't really understand but if she wants it I'll do it.)

He hugs her and pats her head. He also praises her a little more.

"Ku. You're doing well. I'm counting on you from now on."

With a happy look on her face Ku swore again in her heart. She will devote herself to him until the end of her life, using all her cells. She will eliminate all obstacles that stand in her way.

Several days have passed since the commotion over Sirius Black and Peter Pettigrew. The world has already forgotten about the commotion and is in Christmas mood.

Hogwarts is also on Christmas break. There are very few students left at Hogwarts. Among them was Leonard Taylor.

People were gathered in Leo's lab. In addition to Leo, Hermione, and Ku, there were Dumbledore, Snape, Sirius Black, and today's protagonist, Remus Lupin.

"The further improved Wolfsbane Potion has been completed. We will now conduct the final test with Professor Lupin. Headmaster Dumbledore and Professor Snape are also here as witnesses to the effect."

"Show me the list of ingredients."

"Snape didn't care what happened to Lupin, but as a potions researcher, he wanted to know the contents of the new potion. He checks the list that was handed to him. Dumbledore, Sirius, and Lupin also peek in, but he ignores them and checks the contents. As he reads through the ingredients used, everyone who was looking at the list becomes grim. After reading it, Snape throws a question at Leo.

"Taylor, what is this? To me, it seems like nothing more than a potent poison."

"I agree. With this, Professor Lupin will die. It even contains unicorn blood, so even if he survives, it would be better if he were dead."

"Well, this is indeed a potent poison. I will use this to kill only the wolf inside Professor Lupin. This potion is nothing more than a poison as it is, but when you add werewolf blood to it, it changes into a component that kills everything except the human part of the blood owner. The life-giving part of unicorn blood works on humans and the curse part and poison work on wolves. As a result, only the wolf of the werewolf is killed and only the human part survives. I named this potion 'Wolf-Killing Potion.'"

It was an unexpected effect of the potion. Until now, Wolfsbane Potion and Improved Wolfsbane Potion only retained reason or suppressed transformation into a wolf. They had thought that this improvement would make that suppression permanent, but they never thought it would completely remove the wolf.

"Now then, Professor Lupin. Please put your blood in here."

A pitch-black liquid was in the flask handed to Lupin. He puts a drop of his own blood in there. Even when blood was mixed in, its color remained black and did not change. Even Lupin, who trusts Leonard Taylor, hesitates for a moment.

"Oh, I forgot to mention that you'll probably feel very painful at first after drinking it. But you should be fine after a while."

The moment he was about to drink it, unnecessary additional information came out. He decides to go ahead even if he hesitates.

"Guh, ooooooh!"

The moment he drinks the potion, Lupin starts to suffer. His crouching body gradually becomes hairy and his fangs start to grow. His figure completely transformed into a wolf. It's not unreasonable for everyone except Leo, Hermione, and Ku to think that it failed. \n

As Dumbledore and others are on guard against Lupin who has become a wolf, smoke rises from Lupin's body. The next moment, Lupin is engulfed in flames.

"Lupin! Leonard Taylor, what on earth is this!? Do something!"

Sirius Black yells at Leo out of anger. But it was Lupin who stopped him.

"It's okay, Sirius. At first it was painful but now I feel very good. I can feel dirty things leaving from inside my body... I'm definitely being purified right now..."

Despite being burned by flames, Lupin was in a very calm mood. When the flames went out, only Remus Lupin as a human without any hair or fangs was standing there.

"How do you feel?"

"Great. I've never felt so refreshed before. I'm human... I'm human!"

Leo is satisfied with his condition. Lupin is in a state of ecstasy from emotion and Sirius Black hugs his friend in joy.

At that moment, Leonard Taylor overturned another common sense.

During the rest of the Christmas break, Remus Lupin's body was thoroughly examined at St Mungo's Hospital for Magical Maladies and Injuries. As a result, he was proven to be just a human.

Before the end of the year, Wolf-Killing Potion was announced.\n

The reaction of the public was inevitably as shocking as Sirius Black's case or more so. Of course, the joy of werewolves was tremendous compared to anything else.

Including those not known by the Ministry of Magic, humans who had become werewolves came forward and were given Wolf-Killing Potion free of charge and werewolves almost disappeared from the wizarding world.\n

In recognition of this achievement Leonard Taylor was awarded with Order of Merlin First Class.

1993 became a year when various things happened in the wizarding world.

-----------

The proof of Sirius' innocence and Peter's arrest were left up to Dumbledore so they were cut from depiction.

Peter escapes from prison. Fudge is incompetent so he forgot that Sirius was an Animagus just like him.

Peter wasn't sure if he could cross the sea as a rat but he ran out of strength halfway through and was rescued by Muggles on a fishing boat in human form.

Ku is honestly in a state where she doesn't know how she can be defeated. Avada Kedavra would only kill one cell if it hit directly so it's honestly pointless.

When Kuu wanted petting, it was like a dog wanting attention. She had tolerated Hermione's presence without any romantic feelings.

The completion of Wolfsbane Potion renamed Wolf-Killing Potion. It's also a powerful poison so it can be used as a weapon.
