In fact, if it weren't for Yolanda's sworn promise that there would be a way to verify the effect, he would have given up and only talked on paper without conducting exact practical tests, and the potion made in this situation would not have really come in handy anyway.

"Severus, I didn't mean to hide it from you, but I have other plans for this matter, so I will never involve you, you can understand me, right?"

Yolanda winked at Severus with her violet eyes.

“……”

"Okay, put this real potion here first, and after the next full moon, I will tell you about its effect."

Yolanda took the potion that had been bottled.

After the full moon, Lupin returned to class.

He looked like he had just been sick.

His old robes were looser on his body, and there was a dark shadow under his eyes; "Remus, why do you come home every time you come back like you've gone to Half-Life? Are you being bullied at home? ”

Jaime asked, suspicious.

"Mom's condition is getting worse, and I have to take care of her, so I probably don't have a break."

Lupin reluctantly explained.

Yolanda smiled coldly on the side, werewolves are very painful when transforming, because the changes in the structure of the body are very uncomfortable [everyone who has had cramps knows], and most werewolves' sanity will disappear little by little when transforming, just like fainting.

This Lupin is really good at making excuses.

"Stewart, I've already asked the relative, and he said he's willing to try, after so many years of painful transformation, he's willing to try even the slightest possibility."

In the end, his tone already carried a bit of vicissitudes that were not commensurate with his age.

"This"

Yolanda handed him a small bottle, "The relative who gave it to you." Let him take it a week before the full moon. ”

"It's really ......"

Lupin was too excited to speak.

"Don't get too excited just yet, this is just a test piece, Severus and I tried it many times before we made it."

"Eighty percent of the time this potion shouldn't work, and we need to improve it based on your relative's reaction."

Yolanda reminded.

"That's right, Stewart. As you said before, you can record what happened after the werewolf transformed, but how do you record it? ”

"I've thought about this for a long time."

Yolanda pulled out a small box, "Look! ”

Lupin opened the box and asked curiously, "What is this?" ”

He'd never seen anything like it, with a couple of weird buttons on it and a round glass in front of it.

"It's called a camera, it's a Muggle thing, you have to be careful with it, it's very expensive, I won't spare you if it breaks."

Yolanda slapped Lupin's hand away, and then carefully taught Lupin how to use the camera.

"You're going to have to put this camera in a completely safe place, and you're going to have to point it at your werewolf relative, you know, or you're going to be in vain."

Lupin's chick nodded like a peck, "Don't worry, don't worry, Stewart, I'll protect it." ”
