Lin An roughly understood, and at this moment, under Harry's guidance, he was heading towards the bathroom, and as soon as he turned the corner, he heard hurried footsteps behind him.

The three of them were afraid that the prefect would find out, and then hurriedly hid sideways behind a stone sculpture

However, it turned out that it was not the students who came, but Professor Snape.

He walked through the hallway and disappeared from their sight.

Ron subconsciously flinched, "What is he here for?" Could it be that Malfoy ...... so quickly?"

Lin An looked ahead, "No, Draco shouldn't have had time to say it yet. The professor is not going in the direction of the women's bathroom."

"Let's go."

She guessed it was the Philosopher's Stone, and headed down another hallway.

At that moment, Lin An and Harry sniffled at the same time, and a foul stench entered their nostrils.

It was the smell of smelly socks mixed with a public washroom that was never cleaned.

Lin An quickly trotted forward two steps, and then saw the sign of the women's bathroom, and pushed it away without saying a word!

「！」

Inside, Hermione, whose face was full of tears, was startled, and then trembled violently.

Ah, his eyes were red, his fluffy hair was like a mess of lion hair, and when he saw Lin An coming, he hurriedly tried to comb it uncomfortably:

"I'm sorry, you...... Linan…… I mean you'......."

The embarrassment and uneasiness on her face were palpable.

"Shhhhhh Lin An put his index finger to his lips.

On the side, Harry and Ron didn't dare to come out.

Hermione seemed to sense something, and her face turned white. She stood silently at Lin An's side and looked out, only to see that at the end of the passage on the left, a behemoth was moving in this direction.

He slowly walked into a piece of moonlight, and the sight was terrifying.

"It's a troll."

Lin An whispered in a breathy voice.

Hermione's face turned pale instantly.

The troll was twelve feet tall, with dull skin and a massive, stupid body as gray as granite, like a huge pile of sand. On top of it is a small head like a cocoa bean. His short legs were as thick as tree stumps, and underneath were flat, cocooned feet, and the stench emanating from his body was disgusting.

The troll has a thick wooden stick in his hand, which drags on the ground due to the length of his arm. 【Original】

Lin An stretched out his hands, protected the three people behind him and slowly retreated, and slowly closed the door of the bathroom and locked it.

He had barely taken two steps back when he saw the shadow of the troll looming through the window.

He wiggled his long ears and made a decision with his little head, then hung his head, twitched his nose, and stared at the locked lavatory.

The four of them only heard a "bang", only to see the troll smash the door of the bathroom with his stick.

"Ahh

Hermione let out a scream uncontrollably.

Behind them, Ron and Harry trembled, holding her arms left and right and quickly retreating under Lin'an's support.

"Yugadim Leviosa!"

Lin An quickly waved his wand, and the door of the bathroom that had shattered and fell to the ground took off instantly, and with the sound of whistling wind, it smashed into the troll's little head with a "bang".

He stopped, then turned awkwardly, blinking stupidly, trying to figure out what was going on.

But Lin An's heart sank.

She knew that the force of the door just now was not light, and the magical creature was indeed extraordinary.
