I was expelled from Hogwarts?.

After Hermione's "bungee jumping" was over, Rove flew into the air and searched for her.

The teenager shouted, "Hermione, where are you?"

After a while, a muffled voice sounded.

"I'm here... Rove... I'm stuck... Come and save me... Rove."

Rove searched for the sound, and soon found Hermione. When he saw her posture, he almost laughed out loud.

Hermione was inserted into the canopy in an upside-down position, her upper body was stuck by the branches, leaving only half of her body exposed, and she couldn't pull it out no matter what.

Hey, this pose looks familiar, which movie Rove seems to have seen before?
Hermione dangled her legs and urged, "Rolf, what are you doing? Hurry up and save me!"

Rove snorted, bent down quickly, grabbed Hermione's legs, and pulled her out like a carrot.

Hermione sat slumped on the canopy of the tree, scratching her increasingly fluffy hair in shock, and asked, "What's going on here?"

Rove blinked and muttered to himself:
If Hermione knew that he had let the Whomping Willow drag her here, she'd probably fuck him to death.

He thought for a while, pretended to be stupid, and said, "I don't know what happened... let's go down quickly."

Hermione nodded. She struggled to get up, then slumped down and said with a sad face: "Rolf, my legs are weak and I can't get up!"

"..."

Full of guilt, Rolf picked Hermione up and flew towards the ground, then placed her under the tree and let her lean against the trunk.

Shirley took out a bottle of tranquilizer from the box and handed it to Hermione. After she took a few mouthfuls of the potion, her mood stabilized a lot.

Helena walked around the Whomping Willow. She also saw the human face on the trunk. After observing it for a while, she floated to Luo Fu's side and said with suspicion:

"Strange, I never saw this tree when I came to Professor Gryffindor's house."

"Maybe Gryffindor planted it later," Shirley guessed.

"Then why did Rove's face appear on the tree trunk?" Helena asked.

"Rolph, you didn't plant this tree, did you?"

She remembered that Rove told her that he had used a time converter to go back 1000 years ago.

And this Whomping Willow is so tall, it can't be grown in just a few decades or decades, at least it will take hundreds of years.

"It's not me." Rove shook his head: "I've never been here before."

"That's weird." Helena murmured.

In fact, Rove was also very curious, why did his face grow on the Whomping Willow? Could it be that Gryffindor did it?
But when Rove went back to 1000 years ago, he didn't spend much time with Gryffindor. Why did he do such a thing?
"Forget it, forget about the tree for now, let's go to the castle and have a look."

A group of people walked towards the castle, Rove raised his head and stared at the magnificent building in front of him:
It was a majestic stone fortress, with majestic majesty given to it by convex, rough stone walls.

The tower is a hundred feet high, and the stunning dome pierces the sky. The thick Doric columns support the tall vault, adding to its awe-inspiring domineering.

They stepped up the steps, and in front of them was a pair of huge double stone doors twelve feet high, with a golden lion carved in the middle of the two doors.

Luofu pushed the stone door hard, and as expected, the door couldn't be pushed at all.

He looked at the pair of bronze door knockers on the door again. They were not common griffin door knockers, but majestic three-headed lions.

This pair of magic door knockers obviously also has the function of guarding the castle. If anyone tries to force the door, they will turn into three lions to attack the intruders.

"I just wanted to pass through the wall, but it failed." Helena, who was a ghost, said, "There is still a defensive magic left on the wall."

"So we can't get in?" Hermione said with some disappointment.This is Godric Gryffindor's castle. They all arrived at the gate, but were stopped outside. Isn't it a pity?
"I probably can't get in." Helena sighed softly, "It would be great if I knew where the key to the castle is."

"key?"

"Yes." Helena pointed to the keyhole on the door and said:
"There is a key to this door. Professor Gryffindor showed it to me once before, and he said that only with that key can we enter the castle."

"But I don't know where the key is. It has always been kept by Professor Gryffindor, and there is no backup key."

Helena paused, and continued: "After Gryffindor disappeared, I asked the Sorting Hat, and it said that the key was taken away by Gryffindor."

Several people sighed, and it was back to the original point, after all, no one knew where Gryffindor was.

Hermione tried the Arahhodong and other lockpicking spells, but to no avail.

Rove leaned over the keyhole to observe, he thought for a while, and said, "Maybe the Muggle method can open the lock."

"What is the method of Muggle unlocking?" Hermione asked curiously.

Rove smiled, and took out a... iron wire from his pocket.

"..."

"Wizards may have guarded against all kinds of magic, but they never thought about guarding against Muggles." Rove talked eloquently, "Sometimes you don't need a fancy way to open a lock. Simple and unpretentious methods are the most effective, as the saying goes.

Lo and behold! "

Hearing what Rove said, the three girls looked at him expectantly.

Rove stuck a wire into the keyhole and stirred for a long time, only to hear a chirp, and the wire broke inside.

"..."

Rove smiled awkwardly, quickly controlled the wire and got it out.

"Let's go around the castle and see if there is any collapse." Shirley suggested.

Rove glanced at the girl, suddenly his heart moved, and he asked, "Helena, what do you think the key looks like?"

"It looks like..." Helena pondered, frowned and recalled:

"I remember it was silver... very similar to a Muggle cross, but it was an equal-armed cross - the two crossed lines were the same length..."

Helena frowned suddenly and said, "Rove, don't tell me, you have that key?"

Rove smiled, shook his head and said, "I haven't."

Helena breathed a sigh of relief, she was too scared today, and she didn't want to be stimulated anymore, but then the boy's words made her startled again.

"Although I don't have it, I seem to know someone who does."

"Who?!!"

Rove looked at Shirley, who hesitated for a moment, stretched out her slender fingers, carefully grabbed a silver chain from her neck, and lifted it lightly.

At the end of the silver chain was a special cross. The girl with ponytails shook it slightly and asked softly:
"Helena, the castle key you mentioned...does it look like this?"

Helena: "..."
