In the Ancient Magic Office, Hermione looked around curiously. The professor's office looked a little messy. There were two piles of Christmas gifts in the corner, one of which had some boxes unpacked. There were

also some strange items scattered on the large workbench, a palm-sized silver plate with magic symbols on the edge, a dozen dark green coins with a heavy metallic luster, a disassembled magic puppet, a stack of parchment, a few chestnut wood plate-shaped ornaments and magic knives, and two or three books.

Felix noticed Hermione's gaze, "They are all the work content of the recent period, and some of them you have also participated in."

Hermione nodded. The silver plate was a meditation basin that the professor found and needed to be repaired; as for the coins, she had also seen them at the Magic Club's meeting, which could turn into a dark green Ouroboros. She just didn't expect so many of them to appear at once. Could they be new teaching tools?

Or, maybe they were prepared for the Magic Club?

"Sit down for a while while I change my coat." Felix walked into the bedroom and changed into a loose navy blue sweater. When he came out, he found Hermione holding a dark green snake in her hand and teasing it with her other hand.

Hearing footsteps, she explained in a panic: "Professor, it was the coin you put on the table. I tried to sense it with magic and it became like this."

Felix smiled and said: "You can put your wand on its head and silently say: Infinity."

Hermione lowered her head and looked at the snake in her hand. It didn't look scary. It didn't have the slimy feeling of reptiles. Instead, it looked like some kind of metal craftwork. The dark green scales were nested layer by layer and extended to the tip of the tail.

The snake's eyes were black and bright, and it kept shaking with her sight.

She pulled out her wand, gently touched the snake with the tip of the wand, and whispered: "Infinity."

The snake nodded at her very humanely and immediately swam. She felt a little itchy in the palm of her hand, and then it connected head and tail on her right little finger and turned into a ring and stopped moving.

"Is this the Ouroboros Ring?"

"Yes, it's the symbol of the Magic Club. I'll give it to you at the gathering after Christmas. It has two forms: coins and Ouroboros Ring, which can replace the Fennet."

Felix joked, "More than one person has told me that the Fennet is too easy to be mistaken for money. You have to be careful not to pay it out every time."

Hermione studied the snake ring on her hand with great interest and soon found the trick. She waved her hand and the ring moved and turned into a small snake again. Then the snake's body coiled together and turned into the original coin.

Hermione put the coin back on the workbench and pointed at the chestnut wood disc ornament and asked, "What is this? It looks a bit like the Pensieve."

"It's very close. The process of studying the Pensieve was not smooth, but I did imitate it and made some small gadgets. Of course, it can't be compared with the Pensieve, but in the eyes of some people, it should be very interesting."

Felix signaled that she could try it. Many times, Hermione, as an assistant in the ancient magic class, was the first person to try the magic creations he made.

Hermione walked over and carefully examined the chestnut wood disc. It looked very similar to the shape of the Pensieve, but slightly smaller. The edge was clearly carved with magic circuits with a chisel. These circuits were stacked and interlocked, and looked very complicated.

What she hadn't noticed before was that the chestnut wood disc was covered with a thin layer of silver sand. Gently shaking it, the silver sand flowed like mercury.

"These silver things"

"Blank memory fragments, you can think of them as necessary filling materials."

After thinking for a while, Hermione touched the edge of the chestnut wood disc with her wand, and the magic circuits around the disc lit up one by one. The silver sand was squeezed together by invisible hands and floated to a height of one foot, forming a slowly rotating cloud.

She suddenly remembered the bronze smoke that Professor Flitwick demonstrated in a duel class. That magical magic could also be shaped into various shapes, but it needed human control.

And the silver cloud in front of her, made of fine sand, looked more delicate, like a silver liquid light, leisurely stretching and floating.

"What should I do?" Hermione asked.

"Imagine a memory. Hint: don't be too private, because it can read your thoughts."

Hermione was startled, but since it was made to imitate the Pensieve, it must be related to memory. She recalled a memory in her mind, then stretched out a finger and tapped on the silver cloud.

The cloud began to roll, and silver sand fell like rain. Gradually, they piled up a three-dimensional model on the silver plate: that was the scene when she, Harry and Ron fought the basilisk in the Chamber of Secrets in the second year. Hermione

put her head on the table and carefully looked at the tiny "Hermione" on the chestnut plate, which was less than half an inch long. The weird feeling in her heart was hard to describe in words. Similarly, Harry and Ron were only a tiny bit big, and the basilisk was half a foot long, twisting its snake body desperately, and its tail smashed a "big" stone, which looked vivid.

The building of the Chamber of Secrets was also reproduced, including the Slytherin statue, the open space in front of the statue, and the stone pillars with snakes... They all looked so small.

Everything on the chestnut wood plate was like a miniature sand model, except that it moved. From this perspective, the originally dangerous scene became cute.

Hermione stared at it, and the development of the "story" was exactly the same as she remembered, until Harry jumped off the Slytherin statue and stuck the delicate and small sword of Gryffindor into the basilisk's head. The scene stopped. Hermione

stared blankly at the slowly rotating fine sand on the chestnut wood plate, and it took a long time for her to come back to her senses.

"This is, this is..." She racked her brains to describe her feelings, and finally could only say dryly: "It's amazing."

Felix shook his head. He was not very satisfied because this thing was of no use to him. At most, it helped him to open up his mind.

"That's because you haven't used the Pensieve, which can restore all the details in your subconscious. If you have experienced it, you will be surprised to find that your memory contains such rich content, and you know nothing about it..."

"What you just saw was actually the chestnut wood disc reading your memory and then displaying it. Many places are not clear."

Hermione recalled the scene she saw and gradually understood what the professor meant: "That's right, I didn't see you, Professor Snape and Headmaster Dumbledore, but you were actually in the Chamber of Secrets at that time. In addition, some places are also blurry, but they are too small for me to notice, such as the statue of Slytherin."

Felix nodded and smiled, "You will find that you, Harry and Ron are the clearest, because you are most familiar with them, followed by the basilisk, which also left a deep impression on you, and finally the surrounding environment. Speaking of which, your memory is good enough. If someone with a slightly worse memory uses it, the surrounding environment may be a large area of ​​blurry areas, or it may not be shown at all."

Hermione concluded: "So, it just extracts what we can recall naturally and displays it, without reaching the subconscious."

"You've got the point, Miss Granger," Felix said praisingly.
