There is a room for requirement.

In the huge room, tall shelves stood: the right shelf contained a large number of alchemical products, and the left shelf was filled with various potions and conventional materials.

Each one is numbered with a code and placed neatly.

These are all things that William has taken time out of his day to make for the past two years, some of which are practiced, and some of which are about to be sold.

Put it in the room of need, you don't have to worry about losing it at all, and all the requirements of students will be met here.

William needed a "room that only the handsome Stark and the lovely Granger could enter", not a room where things were hidden, and everyone else would naturally be isolated from this room.

At this point, Hermione was busy in front of a crucible.

After signing the deed of sale, she has begun to be infinitely squeezed by William.

Every night, she had to help William make potions or deal with some material chores.

This is a precious opportunity, Potions is different from other subjects, no matter how talented you are, you can't do it without a lot of practice!

Practice makes perfect...... It's very apt in Potions.

And practicing requires capital, which is a luxury activity that burns money...... Those materials are expensive, and not every student has the money, and they make all kinds of precious potions every day.

William's time loop is to make full use of Professor Snape's medicine pantry and practice boiling desperately.

Even, use yourself as a guinea pig and taste the saltiness of the potion.

He's so skilled now

Speaking of guinea pigs...... William thought of Prefect Robert again.

Since graduating from the prefect, William has been deprived of a stable and reliable medicine man, and he is now actively looking for a target.

In line with the habit of not flowing into the fields of outsiders, the twins once recommended their little brother Ron.

Ron was a scumbag with no knowledge and had to do cheap part-time jobs.

The most important thing is that he is short of money!

Medicine people are different...... More money, less things, only one ...... Good body.

Ron could have been a medicine man for William, and in a few years, not only did he not need to ask for money from his family, but he also had a lot of money left over when he graduated.

How nice!

Sometimes, William suspected that Ron was actually the twins who had picked it up from the garbage dump and handed it over to Mr. Weasley.

Why else did this come up with such an idea?

Hermione wasn't afraid to drink William's potion, she trusted his brewing skills.

But William refused, Hermione definitely couldn't be a medicine man, and she was positioned as an assistant and secretary.

During this period of time, regardless of her skills, Hermione's vision has finally improved a lot, and she has also learned a lot of ways to process materials with William.

The girl, dressed in a well-fitting sky blue apron and dragon skin gloves on her hands, began to process the sleepy beans.

Sleepy Beans are an ingredient in many high-end potions, such as powerful sleeping pills, living hell decoction, brain tranquilizer, etc.

Hermione was now making a brain tranquilizer.

This potion calms the irritable patient and nourishes the mind, and is most effective for wizards who have been attacked by the Imperius Curse or the Dementors.

She squeezed the sleepy beans with the side of her daggle, and the beans immediately oozed a large amount of juice, and then she put the juice into the cauldron, and the potion immediately turned green.

"William, I compared it and found that the operation of this step is different from that in the textbook."

Hermione, as in class, asked William about the teacher.

"Hermione, for a potions master, there are no textbooks. The steps in the textbook are nothing more than the personal habits of a potions master.

With the development of time, the recipe for potion boiling and the way materials are processed are changing, and it is normal to be different. ”

"But this method is obviously more convenient than the book, so why not change it?"

William pondered for a moment and said, "The Ministry of Magic's evaluation of Hogwarts teaching is once every seven years.

As long as there are no major problems with the textbooks, they generally do not change them. ”

"For example, the treatment of sleepy beans in the textbook is actually correct in terms of technique, but you are not proficient."

William walked over to Hermione and took the dagger from her.

William first tapped the sleepy bean with his wand, and after fixing it with the Imprisonment Charm, he held the knife in his right hand, the tip of the knife pointed downward, and stabbed it suddenly.

The Sleepy Bean easily breaks through the middle.

He began to slice patiently, a short sharp knife gliding through, each slice evenly sized and as thin as a cicada's wings.

This is not something that students can do.

Treatment of sleepy beans...... William did the same thing in the book at first, but it was too difficult.

Later, in Professor Snape's medicine storage room, William saw a large amount of information and found that the professor used a special squeezing method that allowed the water to be easily dispensed.

Snape's way is better than cutting a sleepy bean with a knife!

But as he became more proficient, William found that cutting the sleepy beans into thin slices was significantly more efficient in terms of juice utilization.

It's a matter of trade-offs.

It's like Professor Snape, who discovered the way of extrusion, and did the same in the early days of material processing.

But now when he went to see Snape teach the Advanced Class Potions, he gave up on squeezing and went back to his old ways.

To put it bluntly, what you see is the second layer, and you imagine that people are only on the first floor, but in fact they are on the fifth floor.

Liberasius Polage, the author of the Advanced Potions Textbook, automatically defaulted to the Potions Master when writing the book.

So the steps in this book are not very friendly to the little wizards.

Of course, there are a lot of backward places in this book, after all, the history is so old that Snape has made dozens of changes in it.

Half an hour later, Hermione put the Brain Tranquilizer in a large blue bottle, and carefully labeled it as Slug Giggs's Pharmacy.

This potion is going to be given to Diagon Alley.

After cleaning up, Hermione sat on the bench with her cheeks on her cheeks and watched William sit in the chair, fiddling with Lockhart's shampoo.

"William, I want to use a polyjuice potion." Hermione said suddenly.

"Who are you going to become?" William asked without looking back.

"Harry and Ron guessed that Malfoy opened the Chamber of Secrets, and Ron said, 'They may have held the key to the Chamber of Secrets, and they have been holding it for centuries, and it has been passed down from generation to generation,'......" Hermione said cautiously.

"I think it's possible...... Dobby was the elf of the Malfoy family, and he had known that the attack was going to happen. ”

William nodded, Dobby's warning was indeed a strange thing, indicating that the attack had something to do with the Malfoys.

"So you want to trick him?"

Hermione snorted. "We're going to take a compound decoction and test him."

"I have a brewed polyjuice decoction here, do you need it?"

"No, I don't need yours!" Hermione shook her head and said seriously, "I can make it myself!" ”

William smiled dumbly, "Blind competition." ”

Hermione sat cross-legged, pressed one cheek to William's back, closed her eyes slightly, and said softly:

"It's not...... Practice your hands a few more times, and I can help with the boiling ...... You don't need to do everything. ”

William was silent.

"What are you up to?" Hermione asked again, "Isn't the bird and snake egg already extracted?" ”

William carefully fiddled with a basin of water and filled it with clean water.

He explained: "It's not a bird and a snake egg, it's just an interest in shampoo. ”

Hermione's voluminous hair is messy, and the softeners on the market have some effect, but they need to be used in large quantities every time to be effective...... William is working on a more powerful shampoo.

Professor Lockhart is a particular person, he is not very good, but he is very attentive to the development of shampoos.

After all, his personal dream is to sell shampoo well.

"This shampoo is very effective, but it has an explosive problem and lacks a neutralizing material." William said.

"If you can find it, you only need a little bit at a time to solve your hair problem."

Hermione let out a soft "um" and rested her head on William's shoulder.

She stared at the blurred reflections of the boy and girl in the water, and was stunned.

The ripples gradually stopped,

Blurred faces,

It's finally clear.

The girl grinned, quietly, and the look in her eyes was like a sweet mountain spring.
