Harry Potter and the Great Old Ones

Chapter 60 The Treasure Hunt at the Room of Requirement
As Tierra walked, she pulled out her wand and rummaged through the messy pile of books on the floor.

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

Tiera waved his wand and put all the books into a canvas bag hanging at his waist.

This canvas bag was borrowed by Tierra from Oliver Wood, the captain of Gryffindor Quidditch. It was enchanted with the Unseen Extension Charm. Normally, every team's apothecary would be equipped with one, and most of them would make their own. However, Tierra doesn't know the Unseen Extension Charm yet, so he has to use Wood's.

It must be said that Wood is not only good at Quidditch, but also makes great magical items. Tierra has already filled this seamless extension bag with thirty or forty books, but there is still plenty of space inside.

Tierra was like a greedy scavenger, stuffing any book that looked like a forbidden book into her bag.

However, there were simply too many books, and in the end, Tiera had to empty all of them and pile them in a particular corner, where two enormous bronze pig statues stood.

Tierra rummaged through his collection of forbidden books, taking only a dozen or so that he knew he could use now.

"An In-Depth Study of Ancient Black Magic Ritual", "The Alchemy of Death and Life", "The Plague", "A Detailed Explanation of Black Magic Item Crafting"...

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

This is the book that Tyrell needs most right now. Facing Voldemort, a master of Legilimency, even if it's just one of his Horcruxes, Tyrell feels like she's walking on thin ice.

After placing the books, Tierra continued on, walked around a tall cabinet, and found four rows of wooden bookshelves, each over two meters tall, in the aisle behind it.

The first bookshelf was cluttered with wands, books, and a bunch of strange items whose purpose I didn't know.

Tiera glanced at the books, put only one book, "The Ritual of Life," into her invisible extension bag, and then went straight to the three wooden shelves behind her.

The three rows of wooden shelves behind were filled with rows of glass jars.

"Hera grass." Tiera opened a glass jar, pinched out a little bit, held it to her nose and smelled it gently, then silently put it back.

“The wings of the Krogya wasp.” Tiera recognized the herbs inside the glass jar with just a glance and put it away. The wings of the Krogya wasp were the main ingredient in the flight potion, or, according to the potions section of the Necronomicon, they could be used to brew a potion that would make the body semi-mist.

The first thing Snape did when he started teaching Tyella was to take her to Snape's own apothecary to identify herbs and potions.

After all, for a pharmacist, your technique may be unprofessional, and your medicine may not be effective, but you absolutely cannot be unable to identify medicinal herbs.

“African tree snake skin!” Tiera’s eyes lit up as she spotted a jar of silver-gray, scaly medicinal herbs on the fourth shelf of the third shelf.

Tierra opened the jar, picked it up, and looked at it.

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

The African tree snake in the Wizarding World is different from the African tree snake in the Muggle world.

The African tree snake, a species of snake in the Muggle world, is a fierce venomous snake of the Colubridae family, measuring 1.5-2 meters in length and ranging in color from bright green to brown or black.

However, the African Tree Serpent 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 feeds on the roots. After being brought to England by a wizard in 1860, it caused great damage to the wand trees in Britain due to the lack of natural predators and is the mortal enemy of the Bowtruckle.

Tiera took out the tweezers she had made herself using transfiguration from her waist, gently picked up a few pieces, smelled them, and then examined their textures.

"Not bad." Tierra put the whole jar of African tree snake skin into the seamless extension bag. African tree snake skin can be preserved for a long time as long as it is dried.

Moreover, the African snake skin sold in regular potion shops is just the shed skin of the African tree snake, while the skin in this glass jar is the snake skin that has been peeled off directly, with the fat layer still attached.

Using snake skin to make compound decoctions can easily cause irreversible deformation in certain parts of the body.

However, snakeskin with a layer of fat is actually more effective for Hydra potions. This jar of African tree snakeskin from the House of Requirement should be enough for Tiera to brew seven or more Hydra potions, but unfortunately Tiera only collected three portions of the other ingredients, and she still hasn't found any scorpion larvae.

After putting away the jar of African tree snake skin, Tierra took several jars of medicinal herbs and then immediately turned and left.

No longer seeking out the Ghostface Moth Pupae, or touching any other magical items that look incredibly bizarre.

Tiera never imagined she could find the pupa of the Ghoul-faced Hawkmoth here.

Since the hawk moth pupa used to concoct the Hydra potion must be alive, Tiera did not believe that the House of Requirement, which had not been visited for many years, would have a hawk moth pupa that met the requirements.

But even without the hawk moth pupa, Tierra was already quite satisfied with finding African tree snake skin.

Tiera's visit to the House of Requirement today, disguised as an invisibility cloak, was a gamble.

Because he really couldn't be sure whether the cluttered Room of Requirement actually had the potion ingredients he needed.

Fortunately, Tiera not only found the African tree snake skin she needed, but also other potion ingredients, such as the wings of the Krogya wasp, the shell of the frog crab, the dried eggs of the pearl worm, and some common herbs, which could be used to brew the atomizing agent from the Necronomicon.

Other ingredients include the claws of the Deathbird, the leaves of the Highland Tower Tree, and the petals of the Stone-Attached Demon Flower. These are the main ingredients for crafting the Deep One Transformation Potion in the Necronomicon.

After leaving the Room of Requirement, Tyella, wearing an invisibility cloak, quietly returned to the Gryffindor common room.

"Fortunately, it's still there."

Tierra didn't rush to take the diary out of the fire. Instead, she took out the book "Brain Occupation: How to Disguise Your Brain" from the Invisible Extension Bag and started reading it.

Because Tiera had previously studied the virtual spiritual dimension in the creation of magical items, she didn't find the Occlumency spell particularly difficult to learn.

After reading the first chapter, "How to Control Your Emotions," Tiera, while not yet fully proficient, was able to construct a special kind of emotional disguise outside her mental walls.

At this moment, Tyra waved her wand and took Tom Riddle's diary out of the fireplace.

"What happened?" Tiera had just picked up the diary when she saw it move on its own without any wind, displaying this line of text.

However, Voldemort's true thoughts were:
[Damn it, does this kid suspect me?]

Although Voldemort can only perceive the world around him through Tyella now, it doesn't mean he was unaware that he had been thrown into the furnace.

Tiera quickly recalled clips of her life in the orphanage in this world.

Tierra grew angrier and more aggrieved, and the more she thought about it, the more she wanted to kill those brats.

Then release all these emotions onto the mental walls.

Feeling wronged, he picked up his notebook and wrote:

“My classmates, my roommates, they bullied me.”

“They poured dirty water on my head, called me a mud-blood, and locked me in a cold storage room.”

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

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