Harry Potter and the Great Old Ones

As Tiera walked, she took out her wand and rummaged through the messy books piled on the ground.

"Powerful Potion", "Dark History", "The Alchemy of Death and Life", "Plague", "Occlumency: How to Disguise Your Brain"...

These books were all put into a canvas bag hanging on his waist by Tiera with a wave of her magic wand.

This canvas bag was borrowed by Tiera from Gryffindor Quidditch Captain Oliver Wood, and it was cast with the Invisible Extension Charm. Originally, every team's pharmacist would be equipped with such a bag, and most of them made it themselves, but

Tiera doesn't know how to extend the traceless spell yet, so he can only use Senior Wood's.

It has to be said that Senior Wood is not only good at Quidditch, but also good at making magic items. Tiera has already put thirty or forty books in this seamless extension bag, but there is still a lot of space in it.

.

Tiera is like a greedy scavenger, putting into bags any books that look like banned books.

But the number of these books was too much, and in the end Tiera had to pour out all the books that had been put in, and piled them in a specific corner, where there were two huge bronze pig statues.

.

Tiera picked through the pile of forbidden books he had collected, and only took away a dozen books that Tiera could definitely use now.

"A Study of Ancient Black Magic Ritual", "Alchemy of Death and Life", "Plague", "Detailed Explanation of Making Black Magic Items"...

Of course "Occlumency: How to Disguise Your Brain" is also included.

This is the book that Tiera needs most at the moment. Facing a master of Legilimency like Voldemort, even if it is just one of his Horcruxes, Tiera feels like walking on thin ice.

After placing the books, Tiera continued to move forward, bypassing a tall cabinet, and found four rows of two-meter-high wooden bookshelves in the aisle behind the cabinet.

The first bookshelf was cluttered with wands, books, and strange items of unknown purpose.

Tiera glanced at the books, put only one book called "Life Ritual" into the seamless extension bag, and walked straight to the three wooden shelves at the back.

The three rows of wooden shelves at the back are filled with rows of glass jars.

"Hera grass." Tiera opened a glass jar, took out a little bit, put it in front of her nose, smelled it gently, and then put it back silently.

"The wings of the Krogya wasp." Tiera just glanced at the next glass jar and recognized the medicinal materials inside, and put the jar away. The wings of the Krogya wasp are the main ingredient for flying medicine.

Raw materials, or according to the records in the Potion Chapter of the Necronomicon, you can brew a potion that semi-aerosolizes the body.

The first thing Snape did when he gave him a small class was to take Tiera to Snape's own medicine storehouse to identify medicinal materials and potions.

After all, for a pharmacist, your technique may not be professional, and your medicine may not be effective, but you must not fail to recognize the medicinal materials.

"African tree snake skin!" Tiera's eyes lit up, and she saw a jar of silver-gray scaly medicinal materials on the fourth row of the third shelf.

Tiera opened the jar, pinched it and looked at it.

Judging from the size and color, it is the skin of an African tree snake that is 50-100 years old.

The African tree snakes in the wizarding world are not the same as the African tree snakes in the Muggle interface.

The African tree snake in the Muggle world is a ferocious and venomous snake of the Colubridae family with a body length of 1.5-2 meters, bright green, brown or black.

But the African tree snake in the wizarding world is a large snake that is 10 meters long, bright silver, and can live for about 120 years. It lives in the roots of trees that can be used to make wands, and makes a living by eating tree roots. It was taken by a wizard in 1860.

After entering the UK, due to the lack of natural enemies, it caused huge losses to the magic wand trees in the UK, making it the sworn enemy of the Bowtruckle.

Tiera took out the tweezers she made with the transfiguration technique from her waist, gently picked up a few pieces in front of her nose, smelled them, and observed their textures.

"It's okay." Tiera put a whole can of African tree snake skin into the seamless extension bag. African tree snake skin can be stored for a long time as long as it is dried.

Moreover, the African book snake skin usually sold in potions stores is just the shed skin of the African tree snake, but the inside of this glass jar is directly peeled off, with a fat layer of snake skin.

Using this kind of snake skin to brew compound potion can easily cause irreversible deformation of certain parts of the body.

But this kind of snake skin with a fat layer is more effective when used for Hydra potion.

The jar of African tree snake skin in the Room of Requirement should be enough for Tiera to refine Hydra potion seven times or more. Unfortunately, Tiera only collected three copies of the other ingredients, and the Grimace Hawkmoth pupa has not yet been found.

Tiera put away the jar of African tree snake skin and several jars of medicinal materials, then immediately turned around and left.

No more searching for Grimace Hawkmoth pupae, or touching other weird-looking magic items.

Tiera, the Grimace Hawkmoth Chrysalis, never expected to be found here.

Because the Grimace Hawkmoth pupae used to refine Hydra potion must be used alive, Tiera did not believe that the Room of Requirement, which had not been visited for many years, would have any Grimace Hawkmoth pupae that met the conditions.

But even if there were no Grimace Hawkmoth pupae, Tiera was very satisfied to find the African tree snake skin.

Tiera wore an invisibility cloak and came to the Room of Requirement today just to gamble her luck.

Because he was really not sure whether the Room of Requirement, which was full of miscellaneous items, had the potion materials he needed.

Fortunately, Tiera not only found the African tree snake skin she needed, but also found other potion ingredients, such as Kroger wasp wings, frog crab shells, dried eggs of pearl worms, and some common herbs, etc.

Can be used to brew the atomizing reagent found in the Necronomicon.

There are also the claws of the death bird, the leaves of the towering tree in the highlands, and the petals of the stone devil flower. These medicinal materials are the main materials for refining the deep diver's transformation potion in the "Necronomicon".

After coming out of the Room of Requirement, Tiera put on her invisibility cloak and quietly returned to the Gryffindor lounge.

"Fortunately, it's still there."

Tiera was not in a hurry to take the diary out of the fire, but first took out the book "Occlumency: How to Disguise Your Brain" from the seamless extension bag and started reading.

Since Tiera has been studying the virtual spiritual dimension in the production of magic items before, Occlumency Tiera is not particularly difficult to read.

After reading the first chapter: How to Control One's Emotions, although Tiera is not yet completely proficient, she can already construct a special emotional disguise outside the mental wall.

At this time, Tiera waved her magic wand and took out Tom Riddle's diary from the fireplace.

"What happened?" As soon as Tiera picked up the diary, she saw the diary automatically turning on its own, and this line of text appeared.

However, Voldemort’s true thoughts are:

[Damn it, does this kid doubt me? 】

Although Voldemort can only perceive the world around him through Tiera, it does not mean that he did not realize it after being thrown into the furnace.

Tiera quickly mobilized the fragments of Tiera's life in the orphanage in this world.

The more Tiera thought about it, the more angry she became, the more aggrieved she became, and the more she thought about it, the more she wanted to kill those naughty kids.

Then release all these emotions onto the mental wall.

Feeling aggrieved, he picked up his notebook and wrote:

"My classmates, my roommates, they bully me."

"They poured dirty water on my head, called me a mudblood, and locked me in a cold utility room."

"Because the senior prefect was dissatisfied that his girlfriend was too close to me, so he burned all my books and notes."

"I only have you left, I only have you left, 嘤嘤嘤."
