Harry Potter and the Virtue of Miss Potter

After saying that, the four little lions entered the castle. Just as they stepped onto a flight of stairs, the stairs beneath their feet began to move.

"Whoa! What's going on?" Wu Mu almost fell over.

“The stairs will change, remember?” Hermione said, holding onto the railing on the left.

When the stairs stopped, Harry started walking forward. "Let's go this way, so the stairs don't start moving again." They pushed open the door, which was dark inside.

“Uh, I don’t think this is the place for us… I… I didn’t bring my glasses. They’re in the dorm, and I can’t see anything right now.” Wu Mu groped for Harry’s hand and took it.

“We can’t come here! This is the third floor, this is a restricted area.” It seemed Hermione wanted everyone to leave from here.

"Let's go." As soon as she said this, the fire in front of her burst into flames.

As soon as they turned around, they saw Filch's cat, Mrs. Loris.

"Meow--!"

“That’s Filch’s cat!” They stepped back.

"Run!"

As the four little lions ran, a fire broke out on the bonfire on the wall.

"Quick! Get behind that door!" Harry saw the door ahead, but unfortunately, it was locked.

"The door is locked!" Harry slammed the lock off the door, looking like he was ready to be punished.

Wumu: "Get out of the way! {Alohomora opens} Alohomora!"

Hermione: "Make way! {Alohomora}"

Woomu and Hermione pushed the two boys away at the same time and spoke simultaneously.

It's natural for Hermione to be a top student and to study ahead of time. It's also normal for Amu to learn some practical spells in her spare time, as she's a Harry Potter fan. She learned this spell before just so she wouldn't have to carry her house key anymore when she went out.

The two more useful girls exchanged a glance and said simultaneously, "Go in quickly!"

"Open the Cave of Alohomora, standard incantation, Chapter Seven..."

"Alright, Hermione, we'll talk about this later, stop talking!" Wu Mu pulled Hermione back.

"Is anyone here, sweetheart?" Mr. Filch walked over with a lantern. He looked around but didn't see anything unusual, or rather, he knew someone was there and deliberately left. "Let's go!"

“Filch is gone.” Hermione breathed a sigh of relief.

“He must have thought the door was locked.” Ron felt a little relieved as they walked further inside.

“There’s a reason this door is locked…” Harry stared at the enormous thing in front of him, frozen in place.

"What did you say? Brother, maybe there's some secret about the school here, or... some suppressed beast, hahaha!" Wu Mu was just glad that they hadn't been discovered, completely forgetting about the third floor.

“You guessed the second one right, Wumu.” Ron looked ahead, his expression gradually turning terrified.

"Huh? What...?" Wu Mu slowly raised his head.

Before them lay a giant dog, hundreds of times their size, with three heads, drooling as it slept. Even more terrifying, it was awake…

Harry, Ambrose, Hermione, and Ron: "Ahhhhh!" The four of them screamed at the same time and ran outside.

The three-headed dog lunged at them, but the four of them used all their strength to push the door shut and lock it again.

"What's wrong with these people? How could they keep something like this locked up in a school?!"

"Can't you use your eyes? Can't you see what it's standing on?" Hermione thought the two grown men beside her were incredibly stupid.

“I didn’t notice its feet; its head was enough to dazzle me!” Ron explained to himself.

"It has three heads! Did you see that? It's so cool!" Although Wu Mu was scared just now, this thrilling but safe adventure made her extremely excited.

“Yes, Wumu, we noticed! Aren’t you afraid at all?” Ron couldn’t believe Wumu’s answer.

"I'm scared! But we're not hurt, are we? We're fine now!"

“It’s standing on a trapdoor, which means it’s useful! It’s guarding something!” Hermione analyzed her recent discovery.

"Guarding something?" Harry was puzzled.

“That’s right. If you don’t mind, Wumu and I are going to sleep now, so you don’t come up with any more crazy ideas that could kill us or worse, get us expelled from school!” Hermione said, pulling Wumu into the dormitory.

Wu Mu didn't react in time and could only stick his head out and wave to them.
