Hogwarts wizards who signed in to Middle-earth...

After finishing his afternoon tea, Dui didn't rush to start making potions, but instead summoned a spellbook.

The cover of the magic book reads "Elementary Transformation Guide".

When Dui returned to Hobbiton from Bucktown, he didn't go straight back along the east-west road. Instead, he deliberately took a detour from the north, visiting Hardshire and Longcliff in the northern part of the Shire to make his mark.

One of the rewards was "History of Magic" obtained by checking in at Long Cliff Town, and "Elementary Transformation Guide" obtained by checking in at Hard Summer Town.

For Duy, "A History of Magic" served little purpose other than passing the time and learning about the history of the magical world.

However, the "Elementary Transfiguration Guide" is different. As a guide to Transfiguration for first and second year students at Hogwarts, the textbook mainly contains some basic Transfiguration techniques, such as transforming everyday objects.

What pleased Dui even more was that, in addition to the Transfiguration Charm, there were also Summoning Charms, such as Clear Spring, Orchid Bloom, and Vanish Charm—all useful spells.

Transfiguration is different from Charms; Charms require unwavering faith and magical power to be successfully cast.

However, Transfiguration is a delicate discipline that requires a great deal of imagination and magical control, making it more difficult to perform than Spellcasting.

The primary stage mainly involves transforming objects, such as turning inanimate objects into another type of inanimate object. The secondary stage involves turning animate objects into inanimate objects.

At the intermediate stage, the transformation involves animals, such as turning inanimate objects into living ones, or living objects into living ones.

As for the advanced stage, it involves human transformation, including the highest achievement of transformation art—the Animagus transformation.

The "Elementary Transformation Guide" that Dui has now obtained only contains basic Transformation content, but it is a timely help for him who is eager to learn.

With the aid of his wand, Dui could easily perform some of the simplest transmutations, such as turning a small match into a needle in one go. However, the larger the object being transmuted, the more difficult the transformation became and the more magic power it consumed.

"Fla~Dimension"

Dui cast a spell on the small wooden bed in the guest room, and the small wooden bed quickly expanded and transformed into a large bed more than two meters long, with the bedding also turning into comfortable velvet and silk.

Dui nodded in satisfaction. Now he wouldn't have to worry about sticking his feet out of bed while he slept.

Then he turned around, smiling, and asked Bilbo, whose mouth was agape, "Would you like me to change your bedding too?"

"Yes!" Bilbo snapped out of his daze, his eyes sparkling as he nodded quickly. This was even more amazing than the previous magic.

A few days after returning to Hobbiton.

After mastering the basics of transformation, Dui began preparing for the task of making potions.

Potions is different from other disciplines, just as Professor Snape said:

"You have come here to learn the precise science and rigorous process of potion-making. Because there are no fools waving wands here, many of you do not believe this is magic."

I don't expect you to truly appreciate the wonderful sensation of a large pot simmering slowly over a low flame, steaming and emitting a delicate fragrance. You won't truly understand the wondrous magic of the fluid that flows into people's veins, captivating their hearts and minds, and making them lose their senses...

I can teach you how to increase your reputation, cultivate glory, and even prevent death—but there's one condition: you must not be the kind of fools I often encounter.

Duy wasn't sure if he was the kind of fool Professor Snape was talking about, but he knew that potions were very important. If he could master potions, he would have an extra chance to protect himself in Middle-earth.

After all, potions have effects that spells cannot achieve, such as healing injuries. Many injuries that would be fatal to ordinary people can be instantly restored to health by simply taking a potion.

There are also compound potions that can transform someone into another person and cannot be detected by spells, truth potions that can make someone vomit secrets, Felix Felicis potions that can make someone lucky, and even elixirs of immortality.

The only problem is that many of the ingredients for making potions cannot be found in Middle-earth, so if you want to make these magical potions, you will have to find substitute potion ingredients.

This requires the skill of a potions master.

However, these questions are far too early for Dui, who is not even a beginner in potion making.

"Potions and Elixirs" only contains basic potion recipes, and some of the ingredients required for these potions are not special and can be found in Middle-earth.

This was Dui's first time actually making a potion, and as a beginner, he chose the simplest scabies potion to practice.

storage room,

Dui set up the silver crucible and preheated it with a kerosene lamp underneath.

Then, put the prepared 6 portions of snake teeth into a mortar and pestle and grind them into a fine powder. After preheating the crucible for 1 minute, pour the powder into the crucible and stir and cook.

With a wave of his wand, the kerosene lamp under the cauldron burst into a large flame, heated for 10 seconds, then reduced to a medium flame, and finally added 4 slugs to steam.

Throughout the process, Dui followed the instructions in the book step by step.

Dui extinguished the flame only after the liquid in the crucible boiled and began to smoke, allowing the crucible to stand for a while.

Two more porcupine quills were added, and then the wand was turned clockwise five times. As it was being stirred, the magic flowed evenly and continuously into the liquid in the crucible along the wand, and the liquid gradually changed color, eventually turning blue, while pink smoke rose up.

At this point, the scabies medicine is ready.

Making scabies medicine is not complicated, but Dui was very satisfied that he succeeded on the first try.

Using a transformation spell, Dui conjured a crystal bottle and poured scabies medicine into it.

"Is that all?" Bilbo, who had been quiet all along, finally asked. He had always been curious about how Dui made potions, so after getting Dui's permission, he watched from the sidelines.

Seeing with his own eyes how Dui made the magical blue potion using snake fangs, slugs, and porcupine quills was a great shock.

"Of course." Dui nodded with a smile, then handed him the potion bottle. "This is scabies medicine. It has a miraculous effect on treating scabies. You can take it and try it on people with scabies."

The scabies potion is a magic potion specifically for treating scabies, with a single purpose. Dui only used it as a practice potion for beginners, so he gave it to Bilbo without hesitation.

Then he began preparing to make potions again, and it was scabies potion once more.

However, this time his purpose was different, so he used an iron pot that Bilbo didn't want as a crucible.

Following the instructions in the potions textbook step by step, Dui did not extinguish the fire when adding the porcupine quills. Instead, he threw the porcupine quills directly into the boiling liquid.

Instantly, the liquid in the pot emitted a sour, green smoke and a sharp hissing sound. The green liquid reacted violently, rapidly corroding the bottom of the pot and splattering everywhere.
