Felix and Newt exchanged addresses. He learned that after Newt retired, he lived with his wife in the countryside of Dorset. They had a "huge" basement for some magical creatures in need to live.

"I don't always keep them. I'm more like a therapist. I will let them return to nature after the 'patients' recover." Newt told him.

Although he guessed the answer, Felix still asked: "Mr. Scamander, if you don't plan to get something from them, how do you keep your love for them for so long?"

Newt smiled and said: "How to keep the love? Of course, it's because of the love itself."

...

The next weekend, at the Magic Club meeting, Felix showed the Ouroboros ring to the members.

He flipped the dark green coin in his hand and let it shuttle deftly between his fingertips. His behavior quickly attracted the attention of these students. The next second, the coin turned into a small snake and condensed into an Ouroboros ring on the little finger of his right hand.

He waved his wand, and dozens of coins flew out from the table in the corner and landed accurately in front of each little wizard.

"It's your late Christmas present."

"It can replace the copper Knut I gave you before. It has two forms: a coin and a ring. You can choose. If you want to turn it into the latter, just say "infinity" and then inject magic. You can try it now."

The members of the club stretched out their hands and let the coin fall into their palms, feeling heavy. Neville, who was attending the gathering for the first time, stroked the lines on the coin. Its surface had a unique heavy luster, but it didn't feel like metal. He looked up at Harry sitting next to him. Harry mouthed to Neville: Basilisk scales.

This was what Hermione told him, and he relayed it to Neville. In fact, when Harry knew this, he was still very surprised. He thought that the basilisk had been thrown back into the Chamber of Secrets after the exhibition, but Hermione told him that the basilisk was a precious magic material and had been divided up by the professor and Snape...

Neville's heart was pounding, as if he had completed some kind of ritual. He clearly and accurately said: "infinity." The coin in his hand changed, and in the blink of an eye it turned into a dark green slender snake.

Neville held it and asked tentatively, "Do you know how to do it?" The little snake swam to his right little finger, wrapped around it twice, and twisted into an Ouroboros ring.

The most excited ones were the Slytherins. Draco Malfoy liked the little snake that the coin turned into almost as soon as he saw it. He couldn't help but extend his index finger to gently touch its head. It was not as smooth as he imagined, but a warm touch, as if it was carved from a dark green gem.

The little snake raised its head and looked at him with its shiny black eyes.

Draco stretched out his finger, and the little snake shook its body and wrapped around his finger, gently swaying its body, connecting its head and tail into a ring. He looked around happily, and caught a glimpse of Pansy Parkinson and Daphne Greengrass from the corner of his eye. Their eyes were wide open, and all their attention was attracted.

The reactions of others were relatively calm. They did not reject the shape of the snake, but they did not show any special liking for it. Cedric wanted to ask if it could be changed to another form, but he thought that this "snake" was not the symbol of Slytherin College, but the Ouroboros symbol in alchemy and magic, representing a certain concept advocated by the Magic Rune Club and Professor Hep himself, so he gave up.

Then he heard Professor Hep's voice

, "Its material comes from a thousand-year-old basilisk. You should have some impression of it. It's the one in the Chamber of Secrets last year. I found that the scales of basilisks have extremely strong magical inertia and it is difficult to channel magic power, but they are also excellent materials for isolating and storing magic power."

"I used basilisk scales as a container and used the powder of African tree snake skin and bird snake eggshell to draw magic runes, and then I got the Ouroboros ring you saw."

When African tree snake skin was mentioned, Hermione glanced at the professor quickly. She knew that this material was one of the important ingredients for making polyjuice potion, but she didn't know that it could be ground into powder and used to draw magic runes. However, she was relieved when she thought that the professor had been troubled by the use of basilisk scales for a long time and had made many attempts.

Felix began to demonstrate. He waved his hand to let the students see a string of practical magic symbols near his wrist, then he brought the ring on his right little finger close to them. The Ouroboros ring suddenly swam, the snake's mouth loosened its tail, and the body shot out to swallow the magic symbols one by one, then returned to Felix's hand and turned into a ring again.

"In practice, I discovered that it can store runes for a long time and delay the dissipation of magic power. Although I haven't found any use for me, the benefits to you are very obvious."

Under the gaze of everyone, he knocked on the little snake's head, and the little snake opened its mouth and spit out the string of runes it had just swallowed. Felix revealed the answer and said, "As long as you successfully outline a rune, you can keep and analyze it for a long time until you are completely familiar with the structure of the rune."

Felix curled his lips, "So, our theme today is cooperation and exchange."

"In the previous few gatherings, you have almost mastered at least one practical rune. Now I need you to exchange with others in exchange for runes that others are good at, at least twenty."

He glanced at Hermione and added, "You can exchange up to three runes from the same person." Otherwise, these students only need to find Hermione alone.

Draco couldn't help but complain: "Professor, this is not fair. There are the least Slytherin students here."

"Well, that makes sense." Felix followed suit. "In that case, let's add one more condition. The person you are exchanging

with cannot be from the same college as you." The other students looked at each other in bewilderment. Felix smiled and said, "You should have seen that I want you to get to know each other. In the previous few gatherings, you all sat together in the same college. This is not conducive to future cooperation..."

"Now, let's get started."

The members of the club began to act. At this time, it was clear who was the most popular among the four colleges. The students of Gryffindor, Ravenclaw, and Slytherin subconsciously surrounded the little Hufflepuff wizard.

The sixth-grade Hufflepuff girl Pete Seldon couldn't help but say, "This is an unexpected development, Warren, you have come to this day." She giggled.

Warren Pardis from Ravenclaw said with a straight face, "Don't be silly, I have helped you many times..."

Ever since Professor Happ called her up last year to compete in the Ancient Rune Knowledge Contest with this girl, and there was no answer parchment at that time, she has been at loggerheads with him. However, the two of them occasionally go to the library together to do homework and look up information, and they have established a unique fighting friendship.

At least that's what he thought.

Harry squeezed outside the crowd. He was always not good at dealing with such situations, especially when he was asked to take the initiative to make friends with some people. But when he noticed that Draco Malfoy's face was not looking good, his mood suddenly became cheerful, as if he was back in Diagon Alley, eating ice cream from Florin's Ice Cream Shop in the summer sun.

Draco noticed Harry's gaze, and he whispered sarcastically, "Potter, you are as annoying as McAdam, why don't you go back to your boxing house."

Harry looked at him in astonishment. He didn't care about Malfoy's bad attitude. Their relationship had never been friendly, but the information that popped out of his mouth was very surprising .

"Have you read "The Adventures of Little Wizard Mick?"

"No, no!" Draco denied it immediately.

Harry said affirmatively, "You have definitely read it. McAdam and the boxing house are both in the book." He suppressed his laughter and said, "And you have read at least the third volume."

Draco's face suddenly darkened. He opened his mouth several times, but couldn't think of a rebuttal.
