"Individual werewolves can control themselves and not hurt people after transforming, but most of them will cause murders, and most importantly, werewolves will not know what they have done after turning back into human form. During the time of his transformation after drinking the potion, no useful memories would be preserved. So, Lupin, it's a dead end that doesn't work at either end. ”

Lupin was silent.

"However, if you really have a way to convince that werewolf relative of yours to drink the real yàn made by a young wizard like us, I have a way to make sure that what happened during the werewolf transformation is perfectly recorded."

A smile crept up the corner of Yolanda's mouth.

"What's the solution?"

Lupin jerked his head up.

"I said that there is a way, there is a way, you first find a way to convince your werewolf relative, and then come to me after you get it."

"Done?"

Regulus asked.

"In a short time, he won't be haunting me."

Yolanda raised an eyebrow, it was almost the full moon, and Lupin was at least going to "go home"

One trip to get his "relative" who had been bitten by a werewolf

The exact reply, and the development of the wolf poison potion, also takes time.

"But it's strange, Sirius is pestering you, why is Lupin pestering you? If it's about potions, he can go and ask Slughorn. ”

Regulus was puzzled.

"Who knows."

Yolanda pretended not to know anything on the surface, but in fact, she knew everything in her heart.

This Lupin had already asked Slughorn, and if he guessed correctly, he should have known that Mrs. Snape was actually from the Prince family.

You must know that the wolf poison potion was first researched by the Prince family, and in terms of the depth of research on this potion, Slughorn may not be able to compare to the Prince family.

Thinking about it this way, the person most likely to develop the wolf poison potion is not the current famous potions master, the dean of the Slejerin Academy, Slughorn, but Severus, who inherited the blood and experience of the Prince family.

Lupin, knowing that even if Severus was in a hurry to study the effect, it would be absolutely impossible to work with Potter's good friends, and it was difficult to start from Severus, so he retreated to the second place and came to himself.

Hum!

I'm afraid he didn't know that finding himself here was far more terrifying than looking at Severus's face, right?

"Severus, how's it going? Is it done? ”

In the Potions classroom, Yolanda and Severus both had their hair greasy and smelled of potions.

"Theoretically, this potion can only be regarded as a barely passing, but even if it doesn't have to be on a werewolf, I know that this kind of potion is absolutely impossible to suppress the control of wolf venom on the brain."

Severus's tone was wolf-like, and it was the biggest and most difficult problem he'd ever encountered since learning potions.

"It's okay, I'll take a look at the effect of this potion first, and then we'll discuss the improvement direction of the wolf poison potion according to the effect, which will be easier."

Yolanda comforts Severus.

"So, you're still not going to sue me, have you come up with any way to test the effect?"

Severus frowned.
