Harry Potter and the Great Old Ones

Chapter 200 Laboratory

Although the second practical lesson of the Defense Against the Dark Arts course ended in an anticlimactic manner, this did not prevent the young wizards from affirming Professor Lupine's teaching level.

Everyone was excitedly discussing Boggart and Tiera's prophecies.

But only Harry, Ron and Hermione care about Tiera herself——

Because Tiera disappeared again.

He ran out of the teacher's office and disappeared.

"Humph, don't worry about him." Hermione said after accompanying Harry to search around. "What danger can he face as long as he is in the castle? He is just looking for a place to be quiet."

Then Hermione hurried to the library with her heavy schoolbag on her back. She had a lot of things to do this semester, but she had no time to care about a crying little boy.

After Hermione left, Harry searched around the castle again. When he finally returned to the dormitory, he found Tiera already wrapped in a quilt and lying on his bed.

"Hey... Tiera?" Harry shook Tiera and said, originally wanting to comfort him, but -

Harry found that Tiera had fallen asleep.

Harry:......

"Alas..." Harry sighed, took off his shoes, then climbed onto the bed and lay next to Tiera——

At the same time, Tiera was wandering in the Slytherin chamber in the form of a "parasite".

Now Slytherin's secret room has been greatly changed. The entire secret room has been transformed into a clean and refreshing laboratory under the influence of Tiera's constant giant bubble head curse——

There is a huge metal door at the entrance to the Slytherin Chamber of Secrets. Behind the door is a wide passage above the water. On both sides of the passage are countless stone pillars entwined with giant snakes——

After being transformed by Tiera, a magic lamp that never goes out hangs on the top of each stone pillar entwined with a giant snake. The light pierces the darkness of the secret room and falls on the carpet that has been laid by Tiera.

And there are rows of bookshelves and medicine bottle cabinets in the aisles.

There are classical and exquisite oil paintings hanging on the stone pillars near the aisle——

Of course, those oil paintings are basically landscape paintings, and only a few of them contain figures——

Or some kind of creature.

After getting these oil paintings from the Room of Requirement, Tiera used magic to erase the characters in the oil paintings, and sealed the passages between these oil paintings and other oil paintings in Hogwarts Castle to prevent others from doing so without her knowledge.

The ghost came to his small laboratory through these oil paintings to prevent the demons he sealed in those oil paintings from running into other parts of Hogwarts Castle——

Yes, after acquiring these oil paintings, Tiera sealed the demons she summoned during the summer vacation.

Just like Tiera's favorite oil painting depicting a church in the afternoon——

There is an extra little devil and a succubus——

Lingering on the pulpit of the oil painting church.

Now this oil painting is only static, but once someone enters the secret room without Tiera's permission, the demons and little succubi in this oil painting will come to life——

Then it possessed the intruder unexpectedly.

The bookshelves and medicine cabinets on both sides of the aisle are filled with some commonly used books, potions, and raw materials that Tiera dug out from the Room of Requirement and Lucius Malfoy requested.

Walking through the corridor that has been modified to look a bit bookish, at the end is a large square platform, and then there is Slytherin's big stone face——

In the center of the square in front of the big stone face, Tiera placed a set of desks and chairs from the seventeenth century, with the big stone face behind it and facing the corridor.

It was a set of tables and chairs from the Baroque period of the 16th century. On the side of the table and chairs facing the aisle were two sofas of the same style and a wooden coffee table.

The decoration on the coffee table is very simple, an elegant vase, and roses with sharp serrated leaves that are waving aimlessly in the vase——

This is the first creature that Tierra has transformed using blood magic. Simply pouring his own blood on an ordinary rose that was picked, it gives the rose powerful life vitality and domineering desire for aggression.

There is also a huge, sun-shaped white light suspended in the sky above the square platform, and the feeling of light is scattered in every corner of the platform.

Along the edge of the platform, there is a circle of experimental benches, which Tiera also took out from the treasure room of the Room of Requirement, or modified and reconstructed using the original objects in the treasure room.

The experimental bench is relatively empty now, with only the glass instruments used in the experiment placed on one of the tables.

After all, Tiera doesn't have much to experiment with right now.

And Slytherin’s big face stone sculpture has been completely transformed by Tiera——

It turned into his own big face. This face is just a simple stone sculpture now. After Tiera improves her demonology ritual, she plans to summon a big demon to seal it into the stone sculpture to become a guardian spirit.

Because from the position of the big stone face and mouth, there is still a space——

It was a rough-hewn stone cave. Tiera spent a lot of time cleaning up the rotten and smelly mud inside, and used the Traceless Extension Charm to slightly expand the space here——

This cave is used by Tiera as a treasure house to store some precious but not very important potions, herbs, raw materials, ores and magic items.

Only a small part of these items came from Lucius Malfoy's political donations, and the rest came from centuries of collections in the treasure room of the Room of Requirement——

Yes, in countless deep dark nights after school started, Tiera relied on the "parasite" and with the help of Dobby, she had basically taken care of the treasure room in the Room of Requirement——

The harvest is not without abundant harvest.

Tiera made a rough calculation——

There are a total of 173 black magic books that are relatively well preserved. Even if they are slightly damaged, the degree of damage does not affect reading. If duplicates are included, the total number is 225.

The badly damaged and fragmented pages, papers and manuscripts containing knowledge about black magic weigh about ten kilograms.

There are fifty-seven non-dark magic books, one hundred and thirty-three including duplicates.

There are a total of 1,777 kinds of herbs, potions, magical animal ingredients and ores that can still be used.

There are more than 350 kinds of magic items in total, of which only 110 are non-dark magic items, and the rest are all kinds of black magic items——

And among all the magic items, forget about the others. Whether they are ordinary magic items or black magic items, except for those with special functions, those who hold the two major artifacts "Parasite" and "Inheriter"

Yela doesn’t like it very much, but there is only one thing——

There was only one thing that Tiera never imagined would appear in the Room of Requirement at Hogwarts, nor would she expect to be found by herself——

It was probably around this time last year, before Tiera refined the "Parasite", when she was looking for Ravenclaw's diadem in the Room of Requirement, Tiera passed by a debris pile.

That pile of debris, or something in it, gave Tiera an extremely dangerous feeling.

Tiera, whose strength was no less than that of an average adult wizard at that time, made her body instinctively seek advantages and avoid disadvantages.

This year, after the start of the third grade, Tiera relied on the two artifacts of "Parasite" and "Inheriter". Tiera began to sort out the pile of debris herself, and found a long strip in the pile of debris.

wooden box.

Tiera opened the wooden box and opened the golden velvet package inside. What appeared in front of Tiera's eyes was an ancient copper-yellow pointed gun. The tip of the pointed gun seemed to be stained with bright red blood.

Tiera carefully picked up the pointed gun from the wooden box. The blood on the gun tip seemed to change and flow with gravity.

Tiera instantly understood what this was——

Spear of Longinus.

Originally I only wanted to update one chapter, but then I thought about it and decided to update two chapters. Anyway, I have enough manuscripts.
