The pages of the book flickered with a dim light, illuminating the surroundings just right, allowing people to read even in the darkest places.

Felix casually sketched a "light" magic rune on it, and the magic book flipped to a position with a "clatter". Then more symbols appeared, like fish smelling bait, constantly connecting with the initial magic rune, from three to five, and from more than ten to twenty.

These are all imperfect magic rune circuits, or magic rune sequences.

He casually grabbed the symbols strung together from the book, which were just silver shadows, but when Felix injected his own magic power, it became completely different, no different from what he had sketched out of thin air.

Felix's heart moved, and he put his attention back on the magic book. Following his thoughts, a complete magic rune sequence jumped out of the magic book, and when his magic power was wrapped around it, it immediately turned into a soft milky white ball of light.

Illumination.

Felix kept trying as if he had discovered a new toy. The magic book was also like a set program that could aggregate and arrange the magic rune sequence according to his wishes.

At this moment, an idea came to his mind, making him feel itchy.

He glanced out the window. It was already dark, but it was definitely worth a try. He came out of the office and walked out of the castle. The light from his silver cloak flashed by, and he slid across the grounds silently. Soon, he appeared in an open space in the Forbidden Forest.

The Forbidden Forest was dark at night, and except for the sound of the breeze, there was silence. And in this silence, from time to time, one or two strange sounds that were obviously made by living things would be heard.

Felix waved his hand slightly, and the Book of Runes appeared and floated in front of him.

He pointed his finger at it and whispered, "Black Lightning... can be activated first. Well, let's start with two." As soon as the voice fell, two illusory shadows flew out of the Book of Runes and hung in front of him.

Felix stared at them for a moment and continued, "Golden Flame is not bad either." Another illusory shadow flew out. Like the black lightning, it transformed between the runes and the specific magic image.

"It would be better if there is some light."

"It also needs some protection."

"What about visual interference?"

Felix, wearing a silver cape, selected a dozen names that he liked in one breath, as if he was ordering food in a restaurant. When he closed the book, there were already more than a dozen blurry shadows in front of him. In the cold night, he was like being surrounded by a dozen ghost lights of different colors.

"This state is really wonderful... It is obviously an illusory magic rune, but it can become real in an instant and bring down thunder." Felix murmured, and he couldn't help but stretch out his hand and pour magic power into the two dark shadows.

The blurry shadows quickly turned from virtual to real, condensing into two black lightnings, "crackling" and exploding the surrounding air. When Felix tried to control it, the black lightning immediately became docile, like flowing water.

"So, the upper limit depends on how many magics I can control?" Felix pondered, waving his hand to disperse the magic. He almost had some concepts, and various tactics could be improved accordingly, but-

"What's going on?" Felix frowned and stared at his hands. His index finger merged with an ancient magic rune, which was flashing a little bit...

He confirmed it twice, and the magic rune was not drilled into his fingernail, but into his skin, as if the skin on his finger had changed differently and could absorb the magic rune.

He stood in the cold wind, thinking carefully, as if he had merged with the surrounding environment.

After a while, he exhaled a long breath, and his eyebrows frowned deeper. He repeatedly confirmed that only a small piece of skin on the index finger of his right hand was like this. It was completely invisible on the outside, but Felix knew the difference.

He could only think of a similar example - Dumbledore had demonstrated to him how to deflect a spell with his bare hands. It was exactly the same as the "magical creatures" that Ms. Ravenclaw told him.

"Am I close to this state?" Felix thought in amazement, "Close to the four founders of Hogwarts, Dumbledore and others?" He couldn't accurately tell who was stronger and who was weaker. After all, the time between them was too long, but one thing was certain, these people's understanding of magic must be better than his.

Was it the change brought about by the Book of Magic Runes? Felix couldn't help but guess that he chose runes as his path and step to understand magic. Later, in the office of Hogwarts Castle, when he first saw Salazar Slytherin's manuscript, he was confused but firm in his confidence; later, by chance, he perfected the Book of Runes.

Does this mean that he has gone far enough on this road?

"A sign of transformation?"

Felix thought that this was a manifestation of his increased affinity for runes, and various resistances might also increase accordingly, but he didn't know to what extent this change would eventually reach and how long the whole process would last.

"Magical creatures? Or rune creatures?"

Felix pondered the difference between the two words, smiled slightly, and the many phantoms behind him disappeared together. He was looking forward to the arrival of that day.

The next day was the weekend, and the little wizards had not yet recovered from yesterday's game. The topic of discussion was inseparable from those wonderful performances. Harry and his friends had intended to use the weekend to catch up on their homework, or imagine what the third project would be like (Hermione's idea), but there were too many people in the common room, and they were enthusiastic enough that they would pass by the corner where they were sitting from time to time, pat them on the shoulder, say "good job!"

or suddenly sit next to them, and ask them for more details with an amazed look on their faces.

"Can you hear the sound in the Black Lake?"

"You can hear it a little bit." Harry muttered.

"Don't your hands hurt when you hit the salmon with your fist?"

"It's protected by magic." Hermione said dryly.

After a morning, Harry finally couldn't help but wink at Ron and Hermione. They crouched and slipped out of the common room and ran to an abandoned classroom, which was where they often practiced magic and was also the site of the duel study group.

"Actually, I don't mind talking about it, but they know what they did to me better than I do." Ron said tangledly. He felt that one of the disadvantages of the projection screen was that it made him lose the ability to express himself.

Just think about it, he just described to the onlookers how scary the giant squid was in vivid detail, "It's much bigger than me!" Someone next to him immediately said that using a magic wand as a spear was too weird;

or he wanted to keep it a secret - "Guess what I saw?" The serious answer was "mermaid camp." Some said "red hair" or "the cover of the bubble head curse." In the end, these listeners left him, the protagonist, aside and argued among themselves about which answer was more reliable...

Ron yawned, tears on the verge of coming out, "Ah - maybe I should go back and catch up on some sleep. I slept too late last night."

"I want to go see Hagrid," said Harry.

"Then let's meet in the library. There will definitely be fewer people there today," said Hermione with finality.

Hermione ran to the library alone. Her two roommates kept asking her about the magic that could "knock out a salmon with one punch" last night. She rolled her eyes and took out a magic rune card and handed it to them.

Parvati and Lavender stared at the card in surprise. There was a picture of a charging bison on it.

"Could Hermione's temper be related to this..." Lavender whispered.

Parvati pulled her sleeve and gave her a look. The two looked over and saw Hermione sticking a furry head out of the bed, looking at them angrily.

Lavender immediately said with a wry smile, "How about... I'll lend you that book for another two days?"
