Extra-Smooth Shampoo

The Room of Requirement.

Inside the enormous room stood tall shelves: the right shelf held a large number of alchemical products, while the left shelf was filled with various Potions and common materials.

Each one was numbered and placed neatly.

These are all things William has made in his spare time over the past two years; some are practice pieces, and others are items that will soon be sold.

Place it in the Room of Requirement, and you won't have to worry about it getting stolen; they'll fulfill all your needs here.

William needs a room that "only the handsome Stark and the lovely Granger can enter," not a room for hiding things; everyone else will naturally be kept out of this room.

At that moment, Hermione was busy working in front of a crucible.

Having signed a contract selling herself into servitude, she has already begun to be endlessly exploited by William.

Every night, she would help William brew Potions or handle some trivial matters related to materials.

This is a precious opportunity. Potions are different from other subjects; no matter how outstanding your talent is, you won't succeed without a lot of practice!

The saying "practice makes perfect" is very apt when applied to Potions.

However, practicing requires capital; it's an expensive and extravagant activity... The materials are pricey, and not every student has the money to brew various precious Potions every day.

In the time loop, William made full use of Professor Snape's medicine pantry, practicing brewing medicine recklessly.

He even used himself as a guinea pig to taste the Potions's flavor.

His skill level is now so high

Speaking of lab rats... William was reminded of Prefect Robert.

Since the Prefect graduated, William has had no stable and reliable drug users, and he is now actively looking for one.

Following their habit of keeping good things within the family, the twins had previously recommended their younger brother, Ron.

Ron was a poor student with no academic background, so he could only do cheap part-time jobs.

The most crucial thing is that he's short of money!

It's different for people who take medicine... They have more money, less work, and all they need is... good health.

Ron could easily be William's drug user; after a few years, he wouldn't need to ask his family for money, and he'd even have a large surplus by graduation.

How wonderful!

Sometimes, William even suspected that Ron was actually picked up from a junkyard by the twins and then given to Mr. Weasley.

Otherwise, why would anyone come up with such an idea?

Hermione wasn't afraid to drink William's Potions; she trusted his brewing skills.

But William refused; Hermione certainly couldn't be a drug user, her role was assistant and secretary.

Over this period of time, regardless of her technical skills, Hermione's horizons have broadened considerably, and she has also learned many methods for handling materials from William.

The girl, wearing a well-fitting sky-blue apron and Dragonhide Gloves, began to deal with the Sopophorous Bean.

Sopophorous Bean are an ingredient in many high-end Potions, such as the powerful sleeping pill, Draught of Living Death, and Brain Elixir.

Hermione is currently making Brain Elixir.

This Potions can calm agitated patients, nourish their minds, and is most effective for wizards who have suffered Imperius Curse or attacks by Dementor.

She squeezed the Sopophorous Bean with the side of her dagger, and the bean immediately oozed a lot of juice. Then she put the juice into the crucible, and the potion immediately turned a light green color.

"William, I compared the instructions and found that this step is different from the textbook."

Hermione asked William, the teacher, just as she would in a classroom.

"Hermione, for a Potions, there are no textbooks. The steps in the textbooks are just the personal habits of a Potions Master."

As time goes by, Potions -making recipes and ingredient processing methods change, so it's normal for them to differ.

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

William hesitated for a moment, then said, "The Ministry of Magic evaluates Hogwarts' teaching every seven years."

They generally don't change textbooks unless there are Damao.

"For example, the way the textbook handles the Sopophorous Bean' problem is actually correct in terms of technique; it's just that you're not familiar with it."

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

William first tapped the Sopophorous Bean with his wand, then used the Imprisonment Charm to immobilize it. He then gripped the knife in his right hand, pointed the tip downwards, and thrust it in suddenly.

The Sopophorous Bean split open easily.

He began to patiently slice the pieces, the sharp scalpel gliding across them, each slice being uniform in size and as thin as a cicada's wing.

This is a technique that students cannot perform.

Dealing with Sopophorous Bean... William initially tried to do it the way the book suggested, but it was just too difficult.

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

Snape's method was far superior to Sopophorous Bean with a knife!

But as William became more skilled, he discovered that slicing the Sopophorous Bean thinly resulted in a significantly higher utilization rate of the juice.

This is a matter of trade-offs.

Just like Professor Snape, who discovered the method of extrusion, this was also done in early materials processing.

But now, when you look at Snape teaching Potions to the advanced students, he has abandoned the squeezing method and returned to the original approach.

To put it bluntly, what you see is the second level, while you only imagine the other person as being on the first level, when in reality they are on the fifth level.

When writing the advanced Potions Class, Libashe Polach automatically assumed that the learners were Potions Master.

Therefore, the steps in this book are not very beginner-friendly.

Of course, this book also has many outdated parts, after all, it is a very old book, and Snape made no fewer than dozens of changes to it.

Half an hour later, Hermione poured the Brain Elixir into a large blue bottle and carefully affixed a Slug & Giggs Pharmacy label to it.

This Potions is for Diagon Alley.

After cleaning up, Hermione sat on the bench, resting her chin on her hand, watching William sit in a chair and fiddling with Lockhart's shampoo.

"William, I'd like to use the Polyjuice Potion," Hermione suddenly said.

"Who do you want to become?" William asked without turning his head.

"Harry and Ron guessed that Malfoy opened the Chamber of Secrets, Ron said, 'They might have had the key to the Chamber of Secrets of Secrets for centuries, passed down from generation to generation...'" Hermione said cautiously.

"I think it's possible... Dobby is the Malfoy family's House-elf, and he knew the attack was going to happen."

William nodded. Dobby's warning was indeed a strange thing, which suggested that the attack was related to the Malfoy family.

So you're trying to trick him into saying anything?

Hermione nodded. "We're going to take the Polyjuice Potion to test him."

"I have some prepared Polyjuice Potion here, do you need it?"

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

William chuckled, "It's just pointless arguing."

Hermione sat cross-legged, pressing one cheek against William's back. She gently closed her eyes and whispered:

"No... After a few more practice sessions, I can help you with the cooking... You won't need to do everything yourself."

William remained silent.

"What are you busy with?" Hermione asked again. "Haven't the Occamy Egg already been extracted?"

William carefully arranged a basin and filled it with clean water.

He explained, "It's not Occamy Egg anymore; they're just interested in shampoo."

Hermione's frizzy hair is very messy, and commercially available hair conditioners help to some extent, but require a lot of application each time to be effective... William is developing a more powerful shampoo.

Professor Lockhart is a meticulous person. He may not be very capable, but he is very dedicated to the development of shampoo.

After all, his personal ambition was for his shampoo to sell like hotcakes.

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

"If you can find it, just a little bit each time will solve your hair problem."

Hermione gave a soft "hmm" and rested her head on William's shoulder.

She stared blankly at the blurry reflections of the boy and girl in the water, lost in thought.

The ripples gradually subsided.

A blurred face

It's finally clear.

The girl grinned, quiet and still, her eyes sparkling like a sweet mountain spring.
