Harry Potter and the Old Ones

The experimental bench is a large workbench carved entirely from fine and magical magic wood, with various magical runes and patterns on the surface.

It is said that under this workbench is the passage leading to the legendary Slytherin Chamber of Secrets.

This workbench is filled with various biological specimens, such as giant centipedes, firebirds, diamond-like dragon crystal, devil's feathers, etc.

On the bookshelf nearby are many potion bottles, mushrooms, herbs, seeds, etc. of different colors, densities, textures and shapes.

The laboratory is filled with a faint herbal aroma and metallic smell, and the light is dim, but you can still see various animal ornaments hanging on the walls, such as antlers, dragon skulls, spider webs and other weird items. These are all research black objects. An important tool of magic.

But Tiera did not move those things. Instead, she rummaged through the seemingly disorganized pile of things piled under the workbench and took out a wide, flat and hollow basin with a metallic texture. The basin was filled with as if It was a mercury-like liquid. Even if Tiera shook the basin so much, the mercury-like thing in the basin would not move at all, like the surface of a mirror.

"Do you know what this is?" Longirsu placed the basin in mid-air between himself and Blelim.

"Um, no, I don't know." Blilim said after racking his brains for a while.

——He swore that he had definitely seen this thing somewhere before, but he just couldn’t remember it now.

"This is called a Pensieve." Tiera sighed helplessly, "This is one of the must-memorize test points for your final exam, and if I remember correctly, I just took you to use it on Christmas, right?" Really, I already seem to see your name appearing on the make-up exam list."

"You know, if you fail a class, we will deduct your scholarship for the next month." Tiera said.

"I, I, I..." Blilim said nervously.

"If you don't want to have your scholarship deducted next semester, I suggest you review hard after you leave this room." Tiera said, "There are still about a month until the final exam. It is unlikely that you will get an O, but you will get an O." An A is no problem."

"Yes, yes Mr. Tiera." Blilim said with a blush.

"Then do you know what the pensieve is for?" Tiera asked again.

"The pensieve allows people to enter the world inside memory, allowing us to see our most vivid memories, and allowing us to recall some memories that we have forgotten or ignored!" Brylim said confidently.

"That's a good answer." Tiera said, "Look, you can still learn it if you study hard."

"So." Tiera pointed at Blelim's forehead, "Do you allow me to extract the memory of your dream?"

"Yes! Yes!" Blilim said excitedly.

Tiera slowly withdrew her finger, and what followed was a crystal clear black silk thread.

Tiera shook, and the thread fell away from his fingers, falling lightly into the pensieve.

The liquid in the Pensieve instantly became turbid, as if someone was stirring it. The originally translucent silver liquid gradually turned gray-black, forming a huge hole in the Pensieve.

"Then let's go." Tiera took Blelim's hand and jumped directly into the pensieve.
