Harry Potter and the Great Old Ones

Chapter 200 Laboratory

Although the second practical lesson of Defense Against the Dark Arts ended rather abruptly, this did not diminish the young wizards' appreciation for Professor Lupin's teaching abilities.

Everyone was excitedly discussing the prophecies of Boggart and Tyella.

But only Harry, Ron, and Hermione cared about Tyella herself.

Because Tiera has disappeared again.

He disappeared after running out of the teachers' office.

"Hmph, don't worry about him," Hermione said after accompanying Harry around the castle. "What danger could he possibly be in as long as he's inside the castle? He's just looking for a quiet place."

Then Hermione, carrying her heavy backpack, hurriedly ran to the library. She had a lot to do this semester and didn't have time to deal with a crying little boy.

After Hermione left, Harry searched around the castle again, and when he finally returned to his dormitory, he found Tyrell already wrapped in a blanket and lying in his bed.

“Hey…Tierra?” Harry shook Tierra, intending to say something comforting, but—

Harry found Tyrell asleep.

Harry: ...

“Sigh…” Harry sighed, took off his shoes, climbed into bed, and lay down next to Tyella.

Meanwhile, Tyrell was wandering through the Chamber of Secrets in Slytherin in the form of a "parasite".

The Chamber of Secrets in Slytherin has been completely transformed. Thanks to Tyella's imposing giant Bubble Head Charm, the entire chamber has become a clean and tidy laboratory.

The entrance to the Chamber of Secrets in Slytherin is a massive metal door, behind which lies a wide passageway emerging from the water, flanked by countless stone pillars entwined with enormous serpents.

After Tiera's modifications, a magic lamp that never goes out hangs high on each of the stone pillars entwined with the giant snake. The light pierces the darkness of the secret chamber and falls on the aisle, which has been carpeted by Tiera and lined with rows of bookshelves and medicine cabinets.

Near the passageway, the stone pillars are adorned with exquisite classical oil paintings.

Of course, those oil paintings were mostly landscapes, with only a very few featuring figures.

Or rather, some kind of organism.

After obtaining the paintings from the Room of Requirement, Tyella used magic to erase the figures from them and sealed off the connections between these paintings and the other paintings in Hogwarts Castle. This was to prevent ghosts from unknowingly using the paintings to reach her small laboratory, and also to prevent the demons she had sealed within those paintings from escaping to other parts of Hogwarts Castle.

Yes, after acquiring these oil paintings, Tierra sealed the demon she had summoned during her summer vacation inside them.

Just like in one of Tierra's favorite paintings depicting a church in the afternoon—

There's one more little devil and one more succubus—

They lingered on the pulpit of the oil painting church.

The painting is currently static, but if anyone enters the secret chamber without Tiera's permission, the demon and succubus in the painting will come to life.

Then, unexpectedly, it possesses the intruder.

The bookshelves and medicine cabinets on both sides of the corridor were filled with commonly used books, medicines, and raw materials that Tiera had found in the Room of Requirement and that Lucius Malfoy had requested.

After walking through the corridor, which had been renovated to have a somewhat scholarly feel, there was a large plaza platform at the end, and then there was Slytherin's large stone sculpture face—

In the very center of the square in front of the stone-carved face, Tiera placed a set of 17th-century desks and chairs, with their backs to the stone-carved face and their faces towards the corridor.

It was a set of 16th-century Baroque furniture, with two sofas of the same style and a wooden coffee table on the side facing the aisle.

The decorations on the coffee table were simple: an elegant vase and a rose with sharp, serrated leaves waving aimlessly inside it. This was the first creature that Tiera had modified using bloodline magic. By simply letting her blood fall onto the ordinary rose that had been picked, she endowed the rose with a strong vitality and a domineering desire for aggression.

A huge, sun-shaped white lamp also floats above the plaza platform, its light spreading to every corner of the platform.

Along the edge of the platform, there is a circle of experimental tables, which Tiera took out from the treasure room of the Room of Requirement, or reconstructed from existing items in the treasure room.

The lab bench is still relatively empty, with only one table containing the glassware used in the experiments.

After all, Tiera doesn't have many places to conduct experiments right now.

The large stone face sculpture of Slytherin has been completely transformed by Tiera—

It has become its own large face. This face is currently just a simple stone sculpture. Once Tiera's demonology rituals are refined, she plans to summon a great demon to be sealed inside the stone sculpture as a guardian spirit.

Because there is another space inside from the mouth of the stone-carved face—

It was a roughly carved stone cave. Tiera spent a considerable amount of time cleaning out the rotten, foul-smelling sludge and then slightly expanded the space using a traceless extension spell.

This cave was used by Tiera as a treasure room to store some precious, but less important, potions, herbs, raw materials, ores, and magical items.

Only a small portion of these items came from Lucius Malfoy's political donations; the majority of the rest came from centuries of collections in the Room of Requirement's treasury.

Yes, in the countless dark nights since the start of the school year, Tierra has relied on the "parasite," and with Dobby's help, has essentially set up the treasure room in the Room of Requirement.

The harvest was undeniably abundant.

Tierra did a rough count—

There are 173 black magic books that are relatively well preserved, and even if they are slightly damaged, the degree of damage does not affect their readability. If duplicates are included, there are a total of 225 books.

The severely damaged and fragmented pages, papers, and manuscripts containing knowledge of dark magic weigh approximately ten pounds.

There are 57 books that are not related to dark magic, or 133 if duplicates are included.

There are a total of 1,770 usable herbs, medicines, magical animal ingredients, and minerals.

There are over 350 magical items in total, of which only 110 are non-dark magic items; the rest are all kinds of dark magic items.

Of all the magical items, the rest were disregarded. Whether ordinary or dark magic items, aside from those with special functions, Tiera, wielding the two divine artifacts "The Parasite" and "The Inheritor," didn't particularly value them. But there was one exception—

There was only one item, one that Tyrell never dreamed would appear in the Room of Requirement at Hogwarts, nor did she expect to find it herself—

Around this time last year, before Tyra crafted the "Parasite," while searching for Ravenclaw's crown in the Room of Requirement, Tyra passed by a pile of junk.

That pile of junk, or something inside it, gave Tiera an extremely dangerous feeling.

This prompted Tyella, whose strength was already comparable to that of an average adult wizard, to instinctively seek advantage and avoid harm.

This year, after the start of the third grade, Tiera, relying on the two great artifacts "Parasite" and "Inheritor", began to sort through the pile of clutter herself, and found a long wooden box in the pile.

Tierra opened the wooden box and unwrapped the golden velvet inside. Before her eyes was an old, bronze-yellow spear, the tip of which seemed to be stained with still-fresh blood.

Tierra carefully picked up the spear from the wooden box; the bloodstains on the spearhead seemed to change and flow with gravity.

Tiera instantly understood what this meant—

The Spear of Longinus.

I originally only planned to update one chapter, but then I thought about it and decided to update two chapters instead, since I have enough drafts saved up anyway.
