Felix was having a very busy life on the first weekend of the new school year.

As the first duel class approaches, he must finalize the third permanent professor as soon as possible. In private, he asked Frieve and Professor McGonagall about their thoughts.

Professor McGonagall politely rejected him, because she was also in the position of vice principal, and there were many trivial matters in the school that she had to worry about.

"If I were to attend once or twice occasionally, I would be happy," she said to Felix.

The progress on the other side was very smooth. Almost as soon as he spoke, Flivi accepted the invitation readily, as if he had been waiting for the day.

From a neutral perspective, Felix also recognized Frieve as the most suitable professor.

As the person in charge of the duel class, he must comprehensively consider the difficulty and learnability of the mantra he taught, because he is facing students from all seven grades of the school.

As an experienced spell class professor, Flivi undoubtedly mastered a lot of skills to simplify the difficulty of spell learning.

In comparison, the barrier of transformation is higher - it is not easy to flexibly apply deformation in duels, it is very challenging for the wizard to cast silently and quickly and imagine in duels.

Even Hogwarts seniors have difficulty in silently performing mature biological deformations, let alone in combat.

"Transformation is the realm of genius, representing the wild and wild way of magic." This is the words written by a duel master who is good at transforming in his magic note, and Felix partially agrees with his point of view.

Office of Dean Ravenclaw.

After solving the invitation issue, Felix and Frive spent nearly a day discussing the improvement of the 'zoom curse' together.

"The zoom spell does not perform well in magical creatures. Of course, it may also be because the current test creatures are only Flober caterpillars, which are not representative." Felix took out a stack of test data from the ring and handed it to Flivie.

The Flober caterpillars are ten-inch-long worms, usually brown, and like to stay in humid environments and see them in the shade of the forbidden forest.

Although the mucus of Flober caterpillars can thicken magic potions, they are not valued because they are too common, comparable to some cats and crocodiles. They are one of the food sources of other magical animals in the Forbidden Forest and are located at the bottom of the entire biological chain.

So Felix used the Flober caterpillar for testing without any psychological burden, and did not have to worry about legal issues. But the results are often not wonderful. Pusses grow on the already ugly caterpillar, which looks daunting.

And the key is that he can't find the problem.

Flivi sat on a chair with blue cushioned feet hanging in the air. He looked through the data and thought carefully: "Is it related to the imbalance of magic?"

"Imbalance?" Felix asked.

"Yes, I recently re-examined this spell. The zoom spell was completed by me with reference to modern magic theory. It can be said that it is a spell. Therefore, there may be incoherence of magic power at the connection."

Felix thought for a while and said, "I have considered this issue, but during the casting process, I didn't feel any strangeness, nor did I feel any stagnation."

"We can try!" Frieve jumped out of the chair, "One person is responsible for part of the work, you cast spells, I will sense."

Felix understood what he meant: "You want to use other magic to amplify your senses and feel the formation and flow of spells? It's really worth a try. I don't have this condition alone."

Flivie laughed, "Isn't this the meaning of cooperation?"

He pointed at himself with his wand and whispered: "Super perception...clear ears and bright eyes...magic power appears...Adid Mo's voice..." Magic light flashed on Flivi's body.

Felix looked at this scene with admiration. Few people could do this. Just solving the problem of multiple spells affecting each other can stump 99% of the wizards.

Soon, Professor Flivie finished his work, his appearance became strange, his ears turned into long bronze trumpets, his eyes were gray, and his face looked like different colors of light flashing on his fairy's face, looking like colorful light bulbs.

Flivi's expression was very strange, and he worked hard to maintain the effect of the spell. He squeezed out a few words from his teeth: "Hurry up... I won't last long..."

Felix's expression was solemn. He deliberately mobilized his magic to make them more active. The light blue light continued to gather, and then a dazzling beam of light burst out.

His spell hit a quill, and the quill made a "crackling" sound, rapidly expanding and becoming larger, from the size of a dagger, turning into a somewhat curved spear in the blink of an eye, and it continued to change.

When the quill extended to half of the office, it finally couldn't bear the Felix magic. It exploded with a bang, and a huge shock wave spread.

The whole office was like a storm passing by, in a mess.

Felix took two steps back against the armor spell. Flivi was directly lifted away because he wanted to maintain the spell. His small head was turned around in the air. He quickly pointed at himself with his magic wand, and then slowly floated down.

The Flivier was staring at the blue powder that was falling down like a dazzling blue galaxy. He couldn't help but say excitedly: "Felix, your magic is too strong, and it has completely changed the structure of the quill."

When he calmed down, he warned: "Don't use this magic on people until it is completely perfected."

Felix nodded, "I think so too. Felix, did you discover anything just now?"

"Oh, it's amazing... I did find something interesting." Frieve waved his wand to restore the furnishings in the room to its original state, and then he shook his wand and threw out a bronze smoke.

The smoke was constantly deforming, transforming into a wizard phantom who was casting spells. Felix recognized that this was the scene where he casted his spell.

"Here, here, and here, there is an extremely subtle imbalance in these three locations." Flivi used the figure condensed by the smoke to illustrate what he saw.

Felix stared at the picture and whispered: "I didn't notice it before."

Flivi smiled heartily and said, "It is indeed difficult to discover by one person's research, but no matter what, we have new ideas."

After leaving the office, Felix went to the Potions Professor's office again, discussed the teaching content of the new school year with Snape, and told him about the invitation of Flivie.

Snape looked at him suspiciously: "I thought you would invite that Lupin."

Felix stared at him and didn't say anything. Do you still don't know why?

Maybe his eyes were too straightforward, which made Snape feel a little angry. "I still have something to do, if you don't mind, Felix..."
