Chapter 4136 4138 [Research and Development Success]

At the end of the fourth grade, on the full moon night of May, Xiang Nan looked at Fenrir with anticipation as he transformed into a wolf again.

"Fenrir, how do you feel?" he asked.

"I feel good." Fenrir, who had transformed into a wolf, sneered. Suddenly, he tore his throat with one claw and poked his left chest with the other claw, pulling out his heart. "I won't let you torture me anymore. I would rather die than be your slave. I am free, hahahaha..."

Xiang Nan was shocked and was about to cast a powerful healing spell to help it heal, but Fenrir had already died.

Even a werewolf would have a hard time surviving after such a severe injury. The wolf king, Fenrir Greyback, was killed.

Seeing such a bloody and tragic scene, Xiang Nan did not feel the slightest sympathy.

For the crimes that Fenrir Greyback had committed, it was absolutely deserved that he should suffer such a fate.

Xiang Nan just felt regretful that he had lost a good experimental subject.

"It seems that the wolfsbane potion really worked. It completely preserved all sanity." Xiang Nan wrote in his notebook.

Because of years of imprisonment and torture, Fenrir had hoped that Xiang Nan would kill him or seek suicide more than a year ago.

However, when it is awake, its hands and feet are locked, so it cannot commit suicide.

After turning into a werewolf, although it can break free with its hands and feet, it has lost its sanity and is completely controlled by its werewolf instincts.

Even though a werewolf has no rationality, he still has the instinct to preserve himself, so it is impossible for him to commit suicide.

This therefore creates a paradox: when it is awake, it wants to commit suicide but cannot; after becoming a werewolf, it can commit suicide but does not want to.

It was not until Xiang Nan invented a qualified wolfsbane potion that Fenrir was transformed into a werewolf while retaining his human sanity, so he finally committed suicide.

Its death proved that Xiang Nan's wolfsbane potion was indeed effective.

"You died a worthy death. I hope that after death, your soul can be liberated and go to the other side." Xiang Nan prayed for Fenrir.

Then he cut off Fenrir's head, and as for the other parts, he simply cast the vanishing spell, making them return to all things and become invisible.

……

In June, a week before the last full moon night, Xiang Nan found Remus Lupin.

"Lupin, here's something for you to drink," he said with a smile, offering the brewed wolfsbane potion.

"What is this?" Lupin asked, frowning as he looked at the steaming cup of decoction.

The color of this potion is very bad. To put it nicely, it looks like burnt coffee. To put it bluntly, it looks like cement mixed with water.

"It's a tonic." Xiang Nan said with a smile, "I noticed that you feel uncomfortable for a period of time every month. It should be due to physical weakness, so I specially made this tonic for you. Drink it. After drinking it, your body will feel much better."

"This..." Lupin was embarrassed.

The reason why he feels uncomfortable for a few days every month is that on the night of the full moon every month, he turns into a werewolf.

In order to avoid being discovered, he would ask for leave two days before the full moon night every month, saying that he was sick or that something happened at home, and then he would go out and hide for two days and return to school after the full moon night.

And every time he transformed into a werewolf, it was a torture, so even if he returned to school, he would feel uncomfortable for a few days, weak and look ugly.

It is probably useless to take tonic medicine for this kind of "disease".

"Don't worry and drink it. Don't you trust me? I guarantee it will work." Xiang Nan said with a smile.

Hearing him say this, Lupin had no choice but to nod.

To be honest, Xiang Nan's potions were indeed well-known in Hogwarts. His hot potion, cold potion, intelligence-enhancing potion, etc. were all very popular and had quite good effects.

If he refused again, it would not only damage the relationship between classmates, but might even expose his secret. So Lupin had no choice but to take the cup of medicine and drink it all.

"Wow, it's so bitter~" he said with his whole body trembling. It was so bitter that his tongue was numb. It was really too hard to drink.

"Good medicine tastes bitter but is good for the disease. You will be grateful to me." Xiang Nan said with a smile.

……

A week later, on a full moon night.

Xiang Nan passed through the entrance under the Whomping Willow, entered a winding tunnel, and finally came to a dilapidated house, which was the Shrieking Shack outside Hogsmeade village.

At this time, Lupin had completed his transformation into a werewolf and was standing in the house with a confused look on his face.

Because he found that he had not lost his mind, but remained sober. This had never happened before, and he couldn't help but feel a little confused.

"How is it? My medicine is effective, right? I told you that you would be grateful to me." Xiang Nan said with a smile.

Lupin was startled and looked quickly in the direction of the sound. Just then he saw Xiang Nan. His expression froze and he immediately fell into panic, fear and shame.

"Don't worry, it's okay. I won't reveal your secret." Xiang Nan waved his hand and said, "Otherwise, I wouldn't make medicine for you."

"Thank you." Lupin was stunned for a moment and finally spoke.

"You're welcome." Xiang Nan waved his hand and said, "I've made quite a bit of it. From now on, one week before the full moon, if you drink one cup, you will stay rational after the transformation, and you won't hurt yourself or others."

"That's great." Lupin said gratefully.

He has always been very kind and worried that he would hurt his parents, friends and innocent people after becoming a werewolf. But with this potion, he no longer needs to be afraid.

"Severus, you are really amazing." He said admiringly again.

Werewolves have been a great threat since ancient times. Their danger level is as high as five stars, on par with dragons, basilisks, leopards, and giant spiders, and they are feared and rejected by wizards and Muggles.

Throughout history, people have sought a cure for werewolves, but to no avail.

Unexpectedly, Xiang Nan actually invented a potion that can keep a werewolf sane after transformation. For werewolves, it is undoubtedly a panacea.

"Thank you." Xiang Nan nodded with a smile, "Maybe I'll get the Order of Merlin for this."

"Yes, you deserve it." Lupin nodded.

Xiang Nan's action will save countless werewolves and is a great merit. He is very grateful.

"But this potion can only treat the symptoms, not the root cause." Xiang Nan added, "I will continue to work hard to develop a potion or spell that can truly cure werewolves."

In Harry Potter and the Mystery, Gilderoy Lockhart once said that he once used a complex humanoid spell to completely cure a werewolf and turned him into a human again.

Although he was bragging and attributed the deeds of an old Armenian wizard to himself, since there is a prototype of the story, it means that there is actually a way to cure werewolves.

It's just that this spell is very complicated, Xiang Nan doesn't know how to do it, and neither does Voldemort, and of course he doesn't know how to study this kind of magic. He hopes that there will be more and more werewolves, so that he will have more minions to obey his orders.

So Xiang Nan still has to explore slowly.

"Thank you." Lupin was grateful to hear him say that.
