The eight eyes of the eight-eyed giant spider trembled, and the two big claws seemed to touch some switch, and the "dadadadada" was connected into one piece.

"Well... test the amplification ability again."

Felix first knocked it out with a coma spell, then used his magic wand to lift a silk-like blue magic power and threw it on the ugly head of the Eight-Eyed Giant Spider. Under his control, the Eight-Eyed Giant Spider's body expanded rapidly, ten feet, twenty feet, and thirty feet.

Felix stopped and walked around it.

‘It’s OK to zoom in, this magic is completely under my control.’

‘But it always feels that it is not very useful.’

Felix observed this scene. Who would make the enemy bigger on the battlefield?

In order to turn your opponent into a dazzling target?

There is obviously a better way.

Felix restored the eight-eyed giant spider to its original state. After some examination, he narrowed it down to the size of his little finger tip. He took out an ordinary transparent glass bottle from the ring and put it in.

"Mr. Eight-eyed Giant Spider, please stay with me for a while."

Next he waved his hand to dissipate the spherical vortex, and more than ten seconds later, eleven large spiders fainted around him.

It looks like I'm dizzy.

He carefully left magic marks on the three eight-eyed giant spiders. With these marks, he could directly find their nests.

The place where the Eight-Eyed Giant Spider entrenched is still too close to the school. Judging from their unscrupulous attacks on humans, the danger is too great, so it is best to let them move a little further.

It's good to be company with the trolls, just at the other end of the Forbidden Forest.

But today it doesn't work, he just had a better idea.

...

An hour later, Felix held a little black dog with three heads in his arms and knocked on the door of Hagrid's cottage.

Hagrid seemed to have just had a meal, with tomato sauce on her beard and humming a small song in a low voice.

He opened the door and showed a hearty laugh: "Felix, your suggestions are very useful, the students responded well... Wait!" He suddenly shouted, trembling from his eyebrows to his beard.

"Lu...Lu Wei..." Haeger's eyes were filled with tears.

Felix looked at him with a smile, "Yes, I'll take Luwei"

“…There is actually a child!”

"Huh?" Felix looked at Hagrid with a question mark, and his head began to sting again.

The next second, he was pulled in by Hagrid's big hand, "Come in quickly, don't let the little guy catch a cold."

Hagrid pushed him into the chair, and his burly figure kept circling in the cottage, muttering constantly: "I think... I think... what did the three-headed dogs need when they were young? First of all, there was a stove, and raw meat, and there were still some teeth left... How could there be no music! His father liked me to play the flute for him the most. Oh my God, Lu Wei actually had a child, and I was completely kept in the dark!"

Felix was stunned for more than ten seconds before he figured out the reason for the matter. He interrupted the busy Hagrid with laughter and cry: "Hagrid, do you still remember my magic? During the summer vacation, turn a magic wand tree into a potted plant?"

Hagrid slowly stopped and said in an uncertain tone: "Of course I remember, don't tell me..." His eyes looked at the little black dog in his arms opposite him, wagging his tail frantically, and looking at him pitifully.

He felt a strong sense of familiarity.

"Yes, I brought Lu Wei to you, I'll keep my word."

Hagrid muttered unremarkable, then grabbed the three-headed dog from Felix's arms and looked in front of him.

The little guy was only half a foot tall, not as big as a Shanghai slap. His body looked like black satin, and his three heads were only as big as walnuts, making a grievance.

Hagrid's hand trembled, "It's really Lu Wei. Look at this claw and nose, his second head is a little small, and he was even smaller when he was born. I thought he was deformed..."

The three-headed dog, Lu Wei, returned to the arms of the "old father", and his four fleshy claws were squeezing Hagrid.

Lu Wei's three heads greedily breathed the smell of Hagrid. After a while, it suddenly turned its head and barked at Felix.

It was this bad guy! He suddenly appeared and turned himself into a little bitch!

"Oh!" Hagrid smiled even happier. "He called that when he was a child, he learned from fangs, but when he had twice the size of fangs, he would never call again."

"Just be happy, Hagrid, I don't know if I did it right, so I didn't think too much about it..." Felix said.

"You're so kind, that's exactly what I want!"

It seemed that Hagrid could not stand up for him. Lu Wei was completely honest. It lay on Hagrid's shoulder, which was particularly spacious for it now. After a while, its three heads began to compete for the raw meat handed over by Hagrid.

"Slow down, slow down, it's all yours." Hagrid said with a smile.

Before leaving, Felix remembers to remind him: "Hagge, if Lu Wei grows to one-third of his normal body size, he will send him back, because he will recover quickly next time. I specially strengthened the intensity of the spell, and I think you can spend about a week with him."

"I know, I know." Hagrid said with satisfaction.

After coming out of Hagrid's cottage and walking back to the castle, Felix suddenly remembered that there was an eight-eyed giant spider hidden in his pocket.

He couldn't help but hesitate, he didn't want to turn back.

Or, it clicked... no one saw it anyway...

But in the end, Felix brought it back to the office.

Lying on the sofa, he lazily watched a movie, but he didn't remember anything at the end.

“The side effects of the mind hut are too big.”

Felix gave himself another cup of potion, and for a moment, he felt better and his mind was not so stinging. He pulled out Ravenclaw's crown from the ring and put it on his head.

A trace of cool breath was constantly released, soothing his tired spirit.

‘It’s really useful!’

Felix felt that his 'reason' ran away from home, and he walked around and finally came back.

He sat up from the sofa, recalled carefully what happened today, and couldn't help but cover his face.

“Too rash…”

He quickly came to the workbench and applied layers of protective spells on the glass bottle containing the eight-eyed giant spider.

"Very good. Now even a three-headed dog will take some time to break it." He said with satisfaction, "just record the time of magic maintenance, and then compare it with the data on Hagrid..."

But then, he suddenly realized a serious question, “If I haven’t improved tomorrow, how can I teach the little wizard?”

Felix stared at himself in the mirror, wearing a crown shaped like an eagle spreading its wings on his head, a sky sapphire set on the eagle's chest, and its wings were decorated with rows of pearls.

Going to class with Ravenclaw's crown will not only make people laugh to death, but also cause trouble.

After a while, Felix came up with an idea, but he was a little resistant to it...

When Hermione knocked on the office door on time, she saw Felix wearing a wide dark brown men's top hat on her head.
