Every world in the multiverse will have its own unique herbs, monsters and ore materials, and different refining techniques must be adopted based on the local materials.

According to Snape, potions are a very rigorous subject.

Before your understanding of potions reaches a certain level, each step must be carried out strictly according to the description in the formula.

If the potion is deviated during the boiling process, the potion will be lost at the least, and the potion will be converted into a poison with severe toxicity.

The potions in the Wizard World will accumulate toxins after drinking them. Due to similar principles, even if the potions in the Harry Potter World are successfully refined, they may have side effects.

This is what traditional Chinese medicine says that medicine is three parts poisonous.

For example, the precious potion, Fuling agent, which is said to be able to improve luck, has a powerful effect, but can even help life in crisis situations.

However, taking Fuling agents can also produce certain side effects, such as making people dizzy, suddenly becoming blind and arrogant, etc.

Old Aojiao Snape asked Xin Sheng to find the materials for the Requiem potion themselves, but Xin Sheng still lacked enough understanding of the alchemy materials in this world.

Anyway, Snape and Xiri seem to have no conclusion yet. Xin Sheng left Natiya to take care of the two, and returned from the secret passage leading to Hogwarts by himself, and went to the principal's office to find Dumbledore.

"No book area? Of course you can enter freely."

Students must obtain the professor's approval if they want to enter the forbidden book area, but Xin Sheng himself is a prospective professor, and there is no such restriction.

Dumbledore did not make things difficult for Xin Sheng, and the benefits other professors should have were not less.

"I'd better remind you as usual."

"There are many books in the forbidden book area that are dangerous, and even record a lot of black magic. In principle, anyone is forbidden to bring out the forbidden book, and as the principal, I am no exception."

The magic books in the Harry Potter world are indeed not simple. Xin Sheng vaguely remembers that the textbooks bought by the little wizards in a certain school year will bite people, which means that they have a certain sense of self.

With Dumbledore's permission, Xin Sheng can be confident and bold in searching for books.

Before heading to the forbidden book area, he first came to the public library to read the materials, intending to go from simple to difficult.

"Thousands of Magical Herbs and Mushrooms", written by Felida Spoel.

This book records most of the herbs and mushrooms in the magic world. It is the favorite textbook textbook textbook for Pomona Sprout, a professor of herbal medicine and dean of Hufflepuff College.

In addition, Xin Sheng also found a wide range of herbal books on "The Complete Collection of Toxicillers", "The Complete Collection of Carnivorous Trees", "The Magical Mediterranean Aquatic Plants and Their Characteristics" in public libraries.

After gradually absorbing and digesting the soul power left by Yue, Xin Sheng's learning and comprehension ability improved greatly. He only took half a day to roughly read all the herbal books that could be found in the public library.

But unfortunately, including "Thousands of Magical Herbs and Mushrooms", there are no records of ghost mushrooms and soul dust moss in all common herbal books.

‘That guy Snape wasn’t trying to make things difficult for me on purpose, right?’

Other auxiliary materials for Requiem potion are easier to find, including Mandela, White Fresh and Black Root.

However, the main ingredient ghost mushrooms and soul dust moss never found any clues.

‘There is no choice, go to the forbidden book area.’

The forbidden book area is located deep in the public library, separated by a rope.

Although he has not officially taken office yet, Xin Sheng has obtained Dumbledore's charter.

Through the inspection of librarian Irma Pins, Xin Sheng officially entered the banned book area.

Most of the dangers of books in the forbidden book area are based on the underage wizard.

There are many books that are not suitable for young wizards to watch and learn, including three unforgivable spells.

The Ministry of Magic stipulates that there are three types of black magic with great destructive power that are prohibited from being used at will.

One is the Heart-Diapping Curse, the second is the Soul-Snatching Curse, and the third is the Killing Curse.

Among them, the Slaying Curse is the widely circulated Avada gnawing melon, and the official name is Avada Sominth.

In addition to the Auror who is specifically responsible for fighting the black wizard, once a wizard is found to use the unforgivable spell, the Ministry of Magic will put him in a wizard prison called Azkaban for life.

Anyway, he had already entered, so Xin Sheng simply took some time to write down the three unforgivable curse, and then slowly study their principles when he has time.

"Let me see, the powerful potion...is not this."

"Ah~ Here."

Xin Sheng found a book called "Dangerous Herbs You Don't Know" in the forbidden book area.

The author of this book is Alvon Steben. The cover of the book looks very old and should be an antique book from many years ago.

Books that can be placed in the forbidden book area are either very dangerous or the value of the book itself is precious enough.

"Hazardous Materials You Don't Know" takes into account both. This antique book has long been out of print, and as the title warns, it does contain a lot of dangerous materials.

Xin Sheng temporarily ignored other contents and found records of ghost mushrooms and soul dust moss in the book.

"Ghost mushrooms will only grow on the sunny side of the forest where there are a large number of ghosts."

"If you contact without any precautions, the ghost mushroom will pull the human soul out of the body, and once you cannot return in time, you will be in danger of life."

"Soul Dust Moss, this translucent bryophyte grows occasionally near the ancient battlefield where bloody wars have occurred."

"Muggles find it difficult to see the entity of Soul Dust Moss. Even wizards need to use specific spells to make Soul Dust Moss appear. It is a very rare material."

"Um……"

Xin Sheng scratched his head in distress: "From Snape's tone, he probably didn't prepare these two materials."

"Let's go to Diagonal Alley and Crush Alley for a while. I hope I can buy it directly. If it really doesn't work, I can only go out and look for it myself."

...

When returning to Hogsmeade Village, Snape and Cialis were still busy with their own affairs and had no time to be distracted.

Xin Sheng greeted Natiya and used Floor powder to move to Diagonal Alley.

There are several ways for wizards to travel. One is to ride the most common flying broom, which is usually used when the destination is relatively close.

If it is a long-distance travel, the best way is to use Floor.com, which is convenient and safe, and the travel experience is also good.

But Floor powder can only be used in buildings with magic fireplaces, which is its biggest limitation.

For example, if Xin Sheng wants to travel from Hogwarts to the countryside of Queensland, Australia, without Floor Network available, he can only choose Phantom Appearance Spell.

Through research in the first half of the year, Xin Sheng has studied the traceless stretching curse and phantom development more thoroughly.

Under the premise of understanding the principle, he can use these two spells without spells, and even make some improvements to them.

If Dumbledore is the guarantor, the improvement will be submitted to the Ministry of Magic, Xin Sheng has a high probability of receiving a Level 3 Merlin Medal.

Of course, he has no idea for the time being.

Most wizards will not submit it to the Ministry of Magic after researching or improving spells.

Doing so will certainly receive a medal of honor, but it is equivalent to fully exposing your research to all wizards in the magic world.

Xin Sheng is not interested in illusory honor unless he needs to show his presence and reputation one day in the future.

‘It’s true…’

Walking out of Bojin-Boke Magic Store, the largest store in the Overturn Alley, Xin Sheng sighed in disappointment.

Ghost mushrooms and soul dust moss are very precious, and there are very few places to use in daily life, and even black market stores in the overturned alley are not always available.

"There is no choice but to find the materials yourself."

Ignoring the little gangsters in the magic world following behind him, Xin Sheng popped up his wand from his sleeve and drew a small circle in front of him.
