Ralph and the others listened to the two Slytherins discussing how to fight back against Gryffindor.

Replace their bath water with some other unknown liquid or add some magical potion to it;

robbed them of their soap, treated them in their own way, and put some magic on them, and so on.

It is conceivable that a fight will break out in the public bathrooms of Slytherin and Gryffindor.

"Pandora and Lily-sensa are coming."

Having received an application to open the door, Claude spoke to them and agreed.

"Good afternoon, everyone! How did you go on a summer vacation?"

As soon as she pushed the door open, Lily greeted everyone loudly and greeted everyone warmly.

Pandora followed her and smiled apologetically at the group.

Snape, who had still had some indignation, immediately smiled on his face.

"I'll go get you something to drink."

Snape said politely, as if he were the master of the place.

Ralph didn't mind either, especially after knowing Severus's situation, they were more casual.

"This is Barty Crouch, a student of Slytherin, your junior."

"This is Lily Yinwans, the senior sister of Gryffindor; She's Pandora, and she's from our academy."

Since neither of them knew each other, Claude introduced them.

"Hello, Crouch Senior. Call me Lily!"

Lily greeted little Barty warmly and held out a hand.

"Hello, Lily-senselle, just call me little Barty."

Barty Jr. shook hands with Lily and said.

"Okay, little Barty."

Lily said with a big grin.

Snape, who saw this scene not far away, took a deep look at Barty Jr.'s back, and when Barty Jr. and Pandora began to communicate, he retracted his smile and put on his smile again.

"Come, Lily, Pandora, your Aledord."

With a flick of Snape's wand, two bottles of Aledford floated in front of Lily and Pandora.

"Thank you, Seaver."

"Thank you, Severus."

The former is Lily and the latter is Pandora.

"You're welcome."

Snape said with a smile, looking down-and-out.

"Senior sister, how do you know we're here?"

Daniel asked curiously.

"Oh, this is a new feature of the Room of Requirement. When Professor Flitwick introduced us to us, we asked him to make your lab friends with ours. If there's someone in there, it'll be shown above."

Lily took a sip of her drink and said with a comfortable face, like a lazy kitten enjoying the petting of a shoveler.

Snape watched with some stupidity.

Barty Jr. looked at the situation and always felt that something was not right, but he couldn't tell.

"The professor is biased, why didn't he tell us."

William listened to Lily's explanation and said with a pout.

"Don't think so, William. Lily and I took on this semester's project, and the professor just told us in passing when we were planning the product."

Pandora explained.

"Okay."

William said embarrassedly and smiled. ….

"Sister Pandora, what are you studying this semester?"

Ralph asked curiously, if it was related to Runiwen, he thought he could go for it. The others looked at them curiously.

"It's the contract paper from last semester. Lily and I just thought it was interesting and gave it a try, but the professor thought it was very promising and gave us some direction, hoping that we would quickly design the finished product."

Pandora said that she was the leader of their magic research group.

"Well, that's right

Ahh

Ralph nodded.

"We may have a part to owe it, Senpai."

William thought about Filch last semester and said with some pride.

"You guys?"

Lily shook her head slightly, incredulous.

"Really!"

William was anxious and wanted to speak, but suddenly he couldn't, after all, they also signed a contract.

Lily glanced at him and said don't pretend, I know it all.

"We really have a copy, we shared one with Headmaster Dumbledore."

Barty Jr. explained.

William gave him a grateful look.

"Yes, yes. That's why I can't say what it is."

He hurriedly added.

"You used it?!"

Lily said aloud, her eyes full of shock, and so did Pandora.

"yes? What's wrong?"

Daniel asked, somewhat confused.

"Are there any side effects?"

Ralph and Claude looked at each other, confused.

"You guys haven't had any problems this holiday."

Snape looked at them and asked.

The Ralph Four and Barty Jr. all shook their heads.

"We don't know, because no one has used it since it was designed. After all, contracts can't be more careful."

Lily explained, and Pandora nodded.

"It's okay, that means that the direction of your contract paper is at least fine, and the underlying magic pattern doesn't need to be drastically modified."

Snape said that he was also extremely talented in magic, having been studying the Dark Arts since his third year or even earlier, and that he had a general understanding of the knowledge of magic patterns.

"Next time you go to Madam Pomfrey, check it out, and let her know that she may have signed an unknown contract."

Pandora said.

"Is this all right?"

William was a little shocked.

"Of course, the health problems caused by contracts are relatively common in the wizarding world, and similar to curses, there are naturally corresponding medical measures."

Lily said.

"Didn't Professor Sgrahorn tell you about your program for this semester?"

Pandora asked.

"Nope. But we have some ideas of our own."

Claude shook his head and said.

"How I don't know."

Snape stared at them wide-eyed.

"Didn't I have time to tell you?"

William said.

"Oh? What is it? Does it taste good?"

Lily asked with interest.

Hearing Lily's inquiry, Snape shook his head helplessly. Ever since he and Ralph formed a potions research group, he would often consider adjusting the taste of potions without affecting their effectiveness. ….

Not to mention Lily and the others, who are just used by them, in the eyes of students like Lily and the others, Ralph and their potions team specialize in potions that taste good.

The previous "unboxing" storm of cold medicine still impressed everyone.

"Huh? Flavor? I don't know. Do you think this potion should be ingestible?"

Claude paused, he hadn't really thought about it, and asked Ralph on the side.

"It should be able to eat."

Ralph thought for a moment and said.

"You can eat it."

William thought for a moment and said.

"What the hell? Can you eat it? Isn't potion just for eating?"

Lily asked eagerly.

"We're going to develop a potion to flavor melon seeds."

Daniel said.

"Give the melon seeds

Flavouring?! Why do you want to eat it?"

Snape patted his forehead.

"Ralph got a pot of sunflowers from Professor Sprout, the kind that produces sunflower seeds. So we wanted to give it a try."

Claude explained.

"Sunflower! Cultivated?"

Snape stood up and asked excitedly.

"Don't get excited, don't get excited. It's been cultivated, and it's a lot."

William waved his hand and pulled Snape back into position.

"A lot of potions can be made, hehehe~"

Snape recalled the potions that were only written down in books, and suddenly laughed a little wickedly.

The rest looked at each other quizzically.

"Alas, Lily, you weren't bullied by the Slytherin girls when you took a shower."

After laughing for less than a moment, Snape turned to Lily and asked.

"No, no, what's wrong?"

Lily said with some trepidation.

"That's good."

Snape put on a genuine smile.

Under Lily's inform, they found that the girls' side was much better than the boys' side.

At the very least, it won't be like the boys' bathroom, where the boys from the two colleges are naked and fighting hand-to-hand.

Everyone respects the privacy of others, but sometimes they can be louder than each other.

Lily said that when she and her roommate were in the shower, they talked about the holidays, maybe laughing a little louder, and the Slytherin witches not far away also started chatting, laughing.

"We took a shower with Hufflepuff, they're so nice, I've learned how to rub someone's back now. Lily, next time you can come to our public bathroom, I'll give it a try, it's very comfortable."

Pandora laughed, eager for Lily to try her hand at it.

Lily agreed expectantly.

Then everyone chatted, and Barty Jr.'s belonging was finally remembered and said.

Lily and the others were curious about the magic research group, and at the request of the two girls, Ralph and the others took them to the magic research group's magic research room.

Inside, they were given a measure of the amount of mana, still using the maximum weight that the Levitation Charm could maintain, and the duration of half of the Maximum Weight.

This is the decision that Ralph made after their discussion.

Originally, the duration of 125g was the same as the maximum weight detection that [Levitation Charm] could hold, and it was the total amount of mana, but the unit used for the amount of marker was different. ….

[In other words, it is the best way to read aloud and listen to books at present, change the source, .huanyuan. 】

And the duration of half of the [maximum weight] can represent the quality of the wizard's mana to a certain extent.

As a result, Lily, Pandora, and Severus all far outnumbered Barty Jr., Claude, William, and Daniel.

But there is still a big gap from Ralph.

However, in terms of magic quality, apart from Ralph, Severus is first, followed by Lily, followed by Pandora, William is fourth, and the next three are Barty Jr., Claude and Daniel.

The gap between Severus, Lily, and Pandora is huge, but overall it's still in an echelon.

William, on the other hand, has a huge difference in stats between him and Pandora, and at the same time compares to Barty Jr., Claude and Daniel, and surpasses them by a wide margin, and he alone becomes an echelon.

This made everyone present curious.

"I feel like I've got an idea."

Claude muttered, and Ralph nodded from the side, apparently too.

Barty Jr. was also convinced by Claude at this point, knowing that it was a topic given to them by Professor McGonagall, and that they needed to write a paper and submit it to the professor.

"What's the idea?"

Pandora asked.

Barty Jr. explained it to them.

By this time, Claude and Ralph had already taken out the paper and began to scribble.

"What is the relationship between the duration of transformation and magic? Quality or quantity?"

Severus repeated, then asked:

"Shouldn't this be a Transfiguration Demonic Research Unit? How did you get here?"

Lily and Pandora nodded approvingly.

"Ugh. It's Ralph."

Barty Jr. sighed and explained to them what had happened. The Magic Research Group started with Ralph's question, and so does the project today.

"We may not be of much help with this, but if you need a wizard to cast a spell, you can come to us. However, Lily and I can help you make a power-up that adjusts your weight, so you don't have to be in such trouble as you are now."

Pandora said.

"yes, I just died when I measured the maximum weight."

Lily couldn't agree more with Pandora.

When they measure the maximum weight, they first estimate their approximate range, then take the median value and let Lily and the others try it in turn.

But after all, they are not in the same grade, and the values of the three Lily are far higher than Ralph's estimates, so they can only continue to add. During this period, I almost encountered a situation where there were not enough "scales".

And I'm afraid that Lily's three people's magic power will suddenly be insufficient, Ralph and they will let them drink a little magic recovery potion every time they test, which is also an extremely wasteful point.

"That's great. That way we don't have to go through the hassle. Sister, can you make the minimum mass of the magic props as small as possible?"

Barty Jr. requested.

"Yes, how small?"

Lily said yes at once. Severus was silent, but the way he looked at Barty Jr. was a little wrong.

"Let's go over there."

William noticed the anomaly and quickly pulled Daniel and ran to Ralph and Claude's side. ….

"Go, go, go."

Pandora waved her hand, took out a pen and paper, and prepared to take notes.

"Huh? 50 pieces of parchment?"

Arrive.

"What did you say?! Parchment?"

Lily was startled, and Severus's expression became a little strange.

"Are you sure it's parchment?"

Pandora asked, steady.

"Yes. May I? It doesn't matter if it doesn't."

Barty Jr. was also a little embarrassed.

"It's a bit tedious, but it's fine. How did you come up with the idea of using parchment as a unit?"

Pandora and Lily looked at it and said.

"No way, someone's [Levitation Charm] can't lift a gram of something. Luckily parchment does, otherwise we'd all have to use feathers."

Barty Jr. said with a shrug.

"Can that person tell me?"

Pandora was one step ahead of Lily.

"No, it's your contract."

Barty Jr. bared his big white teeth and said with a smile.

Soon, Ralph and Claude each filled a piece of parchment.

"I'm kind of craving the Centaurs' secret barbecue."

Slumped on the couch in the magic room, Lily said.

"I want to, too, but unfortunately the school hasn't opened yet."

Pandora responded.

"Why don't we go to Hagrid, he's familiar with the centaurs, so he should do it too."

William proposed.

"Can you eat his taste?"

Claude said.

"Forget it, then."

William said.

"How about we do it ourselves? Ask the house-elves for food, and it's a picnic."

Ralph proposed.

Immediately got the congregation

Consent of the person.
