Save the Bachelor of Heaven

 Chapter 4136 4138 [Research and development successful]

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

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

"I feel very good." Fenrir, who transformed into a wolf, sneered. Suddenly, he tore his throat with one claw, and stabbed his left chest with the other claw, pulling out his heart directly. "I I won’t let you torture me anymore, I’d rather die than be your slave anymore, I’m free, hahahaha…”

Xiang Nan was shocked and prepared to cast a powerful healing spell to treat it. But at this time Fenrir had died of anger.

Even a werewolf would find it difficult to survive after suffering such a serious injury. The wolf king of the generation, Fenrir Greyback, was killed.

Seeing such a **** and tragic scene, Xiang Nan had no sympathy at all.

Based on the sins Fenrir Greyback had committed, it definitely deserved this fate.

Xiang Nan just regrets that he has lost a good experimental subject.

"It seems that the Wolfsbane potion really worked. It completely maintained all sanity." Xiang Nan recorded in his notebook.

Fenrir had hoped that Xiang Nan would kill him or find a way to commit suicide more than a year ago because of years of imprisonment and torture.

However, when it is awake, its hands and feet are locked, and it cannot commit suicide even if it wants to.

After turning into a werewolf, although it could break free with its hands and feet, it lost its mind and was completely controlled by the werewolf's instinct.

Werewolves no longer have reason and the instinct of self-preservation, so it is impossible to commit suicide.

Therefore, it falls into a paradox: when it is awake, it wants to commit suicide but cannot; after turning into a werewolf, it can commit suicide but does not want to.

It wasn't until Xiang Nan invented a qualified wolfsbane potion that turned Fenrir into a werewolf, but he maintained his sanity, so he finally committed suicide.

With its death, it proved that Xiang Nan's wolfsbane potion was indeed effective.

"You deserved your death. I hope that after your 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 directly cast the disappearing spell on the other parts, causing them to return to all things and become invisible.

…

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

"Lupin, let me give you something to drink." He said with a smile and offered the prepared wolfsbane potion.

"What is this?" Lu Ping looked at the steaming cup of decoction and couldn't help but frown and asked.

The color of this potion is very poor. To put it mildly, it looks like burnt coffee. To put it harshly, it is like cement brewed with water.

"It's a tonic." Xiang Nan smiled and said, "I noticed that you feel unwell for a period of time every month, probably due to physical weakness, so I made this cup of tonic for you. Drink it, drink it After that, your health will be much better."

"This..." Lu Ping felt embarrassed.

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

In order to avoid being discovered, he would take leave two days before the full moon night every month. Either he was sick or something happened at home, and then he went out to hide for two days, waiting for the full moon day before returning to school.

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

Drinking tonic for this "disease" should be useless.

"Don't worry, drink it. You still can't trust me? I guarantee it will work." Xiang Nan said with a smile.

Seeing what he said, Lu Ping had no choice but to nod.

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

If he refuses again, he will not only damage the relationship between his classmates, but may even expose his secret. So Lupine had no choice but to take the cup of medicine and drink it in one gulp.

"Wow, it's so bitter~" he said with a shudder. It was so bitter that his tongue was numb. It was so unpleasant to drink.

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

…

A week later, it was a full moon night.

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

At this time, Lupine had completed his werewolf transformation and was standing in the room with a blank look on his face.

Because he found that he had not lost his mind, but remained awake. This was something that had never happened before, which made him a little confused.

"How about it, my potion will work, I said you will be grateful to me." Xiang Nan smiled.

Lu Ping was startled, and quickly looked for the sound, and happened to see Xiang Nan. He couldn't help but froze, and then fell into panic, fear, and shame.

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

"Thank you." Lu Ping was stunned for a moment and finally said.

"You're welcome." Xiang Nan waved his hand and said, "I've been through it for a while. From now on, one week before every full moon day, you only need to drink a cup and you will stay sane after the transformation, so that you will not hurt yourself or others. ”

"That's great." Lupine said gratefully.

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

"Severus, you are really amazing." He said with admiration.

Werewolves have been a great threat since ancient times. Their danger level is as high as five stars. They are on par with dragons, basilisks, venomous leopards, acromantula, etc., and are feared and ostracized 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 could keep a werewolf sane after transforming. It is undoubtedly a panacea for werewolves.

"Thank you." Xiang Nan smiled and nodded, "Maybe I will get a Merlin Medal for this."

"Yes, you deserve it." Lupine nodded.

Xiang Nan's move will save countless werewolves, which is a great merit, and he is very grateful.

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

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

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

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

So Xiang Nan still has to explore slowly.

"Thank you." Lupine was very grateful to hear him say this.
