You know, Billywig flies very fast, and it won't give you a second chance to cast a spell."

After Professor Oren finished carefully explaining the points that needed attention, he continued, "Let's practice the spell without using the wands. Please repeat after me - relax your strength and release your energy!"

"The strength is loosening!" the little wizards said in unison.

"Very good." Professor Oren said with satisfaction: "The next step is to test the effectiveness of your spell."

He asked the whole class to line up and come forward one by one to cast a spell on the Billywig worm in the cage.

The first one is Kanna.

She was originally in the middle of the team, but was soon surrounded by Gryffindor fans and moved here.

Ever since Professor Oren called out their name, these little lions have been wanting to see what is so special about this little witch that she could conquer Snape.

"Brave girl." Professor Oren smiled and said, "I remember your name is Kanna, right?"

"Yes, Professor."

After the experience of the first two times, Kanna is now in much better condition than before.

Although she was still nervous, at least she could communicate normally now, and the first thing she thought of was to answer the professor's questions instead of turning around and running.

"Don't be afraid, it's just a simple spell." Professor Oren said patiently: "Remember what I just said, concentrate, you can do it, believe in yourself."

Kanna took a deep breath, closed her eyes, and thrust her wand out with all her strength.

"Strength, strength, release!"

"Swish!" A sound of air cutting was heard in the air.

Professor Oren at the side subconsciously took a small step back.

To be fair, with this force, if you're close enough, you don't even need any spells, you can just stab the Billywig worm to death.

Fortunately, the result is good.

As the spell ended, the Billywig worm in the cage fell to the ground.

"Not bad, one point for Hufflepuff," Professor Oren said loudly, pulling out a second cage.

Yesterday, because he had no experience, he brought three Billywig worms with him when he taught Ravenclaw and Slytherin.

I thought it was enough, but it turned out to be totally insufficient. Sometimes the third one fell down before the first one recovered.

And every time this happened, the young wizards from the two academies would stare at him, and the scene was extremely awkward.

In order to prevent similar situations from happening again, he brought ten of them here today, which was definitely enough.

"It's your turn next, Santos."

Santos, whose name was called, hurried forward and began to chant the spell.

"The strength is loose and the energy is drained..."

Nothing happened, the Billywig worm in the cage was still spinning happily.

"Relax, don't be so nervous." Professor Oren walked up to him and said softly, "Make sure you recite the spell clearly. The last note you pronounced was too soft. Let's try again."

Santos nodded and held out his wand again.

"The force is loose and the energy is released!"

This time it worked.

"Very good, next one..." Professor Oren changed another cage.

The success of two people in a row gave the others a lot of confidence, and they couldn't wait to give it a try.

However, also because of being too confident, some people completely forgot what Professor Oren had said before, and when it was their turn, they didn't even look at the cage, but directly recited the spell loudly into it.

The result of doing this was that the Billywig worm was not harmed, but the cage fell apart.

Therefore, Professor Oren had to be extremely alert later on to ensure that he could restore the cages to their original state as soon as possible.

But he soon realized that he had oversimplified things.

Originally, he just wanted to practice in advance, and then surprise everyone when it was his turn...but he forgot that he had his wand.

Next to the podium, Professor Oren, who was chanting the repair spell, suddenly felt his legs go weak and he collapsed to the ground in an instant.

If it was just a fall, it wouldn't be a big deal. After all, Professor Oren is a strong adult wizard. At most, it would just be a few scratches, which can be solved with a white band-aid.

But the problem was, his repair spell was interrupted.

A Billywig worm broke free and rushed towards the little wizards in front of it angrily.

It had wanted to do this for a long time. It had been left completely powerless since yesterday, and now it had to take revenge no matter what! Faced with this situation, some of the little wizards began to run around the classroom in panic, while others raised their wands.

"The force is loose and the energy is released!"

"The force is loose and the energy is released!"

…

More than a dozen spells crossed each other. Although they failed to hit the Billywig worm, they successfully stopped it from moving forward...

Now, the little wizards were even more excited, as if they had discovered a new world. They raised their wands again, ready to hit the moving target again.

"Stop!" At this moment, Professor Oren, who was lying on the ground, suddenly shouted.

He pulled out his wand and shouted as the Billywig worm flew over his head.

"Everyone is petrified!"

Professor Oren reached out to catch the fallen Billywig worm, put it back into the cage, and stood up tremblingly.

He rubbed his waist somewhat painfully.

No wonder people say that being a Defense Against the Dark Arts professor at Hogwarts is a tough job. It actually makes sense.

Enduring the pain, Professor Oren looked at the young wizard with concern and asked, "Are you all okay? Were you stung?"

"No, Professor." Everyone shook their heads.

"That's good." He breathed a sigh of relief, and after repairing the podium, he said, "Then let's continue the class. By the way...except for the first person in line, everyone else put away their wands."

Everyone did as instructed.

Although they were still a little unsatisfied, after seeing Professor Oren's angry look just now, they didn't dare to mess around anymore.

After all, no one wants to be cursed by the petrification curse.

With this mentality, almost everyone can succeed at once, and the progress is much faster than before.

However, Professor Oren did not seem to relax at all. On the contrary, he became even more nervous.

When the get out of class was over, he didn't even leave any homework and left the classroom without looking back.

This class really made him exhausted, and he really didn't want to stay even a minute longer.

Oren returned to the office, closed the curtains, and took a sip of black tea with satisfaction.

Anyway, it's finally over. Although there were some accidents, they were all under control, and all ten Billywigs were... huh?

Wait, how come there are only nine left? Oren quickly put down his teacup and counted them carefully twice.

Yes, there is one missing.

One cage was empty, with a fist-sized hole in it.

"Merlin's beard..." Oren hurried back to the Defense Against the Dark Arts classroom, but he found nothing there.

"It must be those new spells that hit the cage just now!"

Oren looked at the open window in the classroom and said in annoyance, "Fifty Galleons, just gone!"
