Rove tapped his wand along the walls of the hallway, but after searching for a long time, he couldn't find the partition mentioned by the basilisk.

The boy pondered for a moment, and suddenly remembered something, and suddenly he turned around, walked briskly back to the fireplace that had been checked, and examined it carefully.

The fireplace was unremarkable, and there was a charcoal fire burning in the hearth, but Rove stared at the shape of the flame, vaguely feeling that it looked like a snake that was constantly shaking.

The boy looked more and more likely, and he waved his wand, extinguished the flames, and then removed the layer of charcoal ash, and sure enough, he found a small statue in the shape of a snake.

Rove hissed in a parseltongue, and the little snake dragged its body upwards as if it had come to life, and the partition was dragged up, revealing a square hole for a person to pass through.

He looked into the depths of the hole, which seemed to lead to the deepest part of the castle.

Rove snapped his fingers, and a ball of flame fell downward, but the hole was so deep that soon only a faint light could be seen at the bottom of the depths.

Seeing nothing to see at the bottom of the cave, he went into the fireplace, jumped straight down, and plunged into the endless darkness, his wand lit up to illuminate the dark crevices in the black walls.

After flying for a long time, the boy landed on his feet, and when he looked around, he saw that it was a large open space like an auditorium, and the bonfire burned among the stone pillars, and the smoke blackened the roof of the cave.

Four passages meet here, each with no end in sight.

Rove frowned, he didn't expect the road to the Chamber of Secrets to be so intricate before Corvinus remodeled Hogwarts' pipes.

Just when the boy hesitated, ready to cover the passage casually, a breeze suddenly blew, as if someone had blown a gentle breath, and his sleeves drifted in a certain direction with the wind.

Rove narrowed his eyes, feeling the breeze lingering around him, and he didn't hesitate for long before holding his glowing wand and sailing with the wind.

The passage was long and dark, surrounded only by curved stone walls, and the floor beneath his feet seemed to be slowly moving and tumbling, trying to trap the boy.

Rove walked a long way, and when the wall finally came to an end, a wooden door appeared, with no handle or keyhole, only an eagle-shaped bronze knocker.

Rove frowned, this place is exactly the same as the entrance to the Ravenclaw common room, could it be that behind the door is the Ravenclaw Tower?!

The young man wondered in his heart, how could he come to Ravenclaw Academy at least a thousand meters deep underground?

He knocked tentatively at the door, and the hawkbeak opened at once, and asked in a gentle, musical voice:

"You've never seen a crow, but you see a green apple, so what happens to the probability that all crows are black?"

After a moment's thought, Rove replied, "The probability that all crows are black will increase. ”

"Correct." As soon as the voice was finished, the door creaked open.

Rove stepped into a circular room, only to find that it was not a Ravenclaw lounge, but more of a small ...... Library.

A towering circular bookshelf clings against the wall, thousands of leather-bound magic books, and boxes and boxes of ancient scrolls...... Stacked on top of each other to the roof.

In the center of the room is a bookcase and a chair.

On the table, in addition to a closed magic book, there was also a piece of parchment, the pen and ink on which had not yet completely dried up, presumably someone had been writing here.

Rove suddenly heard the sound of rushing water, and he walked deeper into the room, and found a small door next to a pair of sphinx statues, and pushed it into a cave.

The cave is empty and deep, and the stone teeth hang on the top of the cave, which looks strange and terrifying.

Not far away, there is a lake as clear as the sky.

In the mist, a beautiful witch sits alone on a mossy rock by the edge of a deep lake, holding an oak comb and gently combing the green silk.

Rove walked over slowly, and after seeing the witch's appearance clearly, he hurriedly said:

"Sorry...... Professor Ravenclaw, I didn't know you were here. ”

"It's okay, I guided you." Ravenclaw turned around, she stared at Rove, and asked calmly:

"Who told you there's an entrance under that fireplace?"

"In our time, that hallway had no fireplace, it was converted into a washroom, and there was a pipe to the Slytherin chamber."

Rove looked at Ravenclaw, who was combing his hair, and explained:

"I went into the chamber and took the basilisk with me, knowing that the entrance was nearby, and then I found it...... Professor, where is this? ”

Ravenclaw stretched out her green fingers and gently stirred the icy water, the surface of the lake rippled, and she said softly:

"You can think of this as a ...... My secret room, where I study magic on weekdays. ”

"How many other passages lead to the Hufflepuff and Gryffindor chambers?" Rove guessed.

"That's right." Ravenclaw nodded, "The four of us used to meet each other to exchange magical tips. ”

Rove raised an eyebrow, how did it come to his time, only the Slytherin Chamber of Secrets remained?

Did the other three rooms be closed, or did Corvinus deliberately cover up the entrances to the other rooms when he built the plumbing system?

Ravenclaw said in a soft voice, "You want to enter the Slytherin Chamber of Secrets again and find the basilisk he raised?" ”

"Yes." Rove said honestly: "I want to ask the basilisk some questions and see what the difference is between it and a thousand years from now." ”

"No need to go." Ravenclaw said lightly: "Salazar took the basilisk with him when he left. ”

"But...... The basilisk told me that Slytherin had left Hogwarts without taking it with him, and that it had remained in the Chamber of Secrets. Rove wondered.

"It lied to you." Ravenclaw glanced at Rove and said slowly:

"That basilisk was trained by Salazar himself, and it's so good at lying that it's as natural as breathing."

"So......" Rove narrowed his eyes and said slowly, "Will Slytherin come back to Hogwarts again in the future and leave that basilisk behind?" ”

"Maybe." Ravenclaw didn't seem to care too much, she stared at the boy like a torch, and said in a cold voice:

"I've got something to do with you."

"What's the matter?" Rove hurriedly asked.

Ravenclaw stood, her long hair cascading down her back, and she wore a silk gown woven with ivory brocade and silver thread, which was extremely close to her body and drew a graceful curve.

A sky-blue robe appeared behind Ravenclaw, and she stretched out her arms, the robe automatically slipped on her, obscuring the lines.

Ravenclaw, with his naked jade feet that do not stir up the slightest dust, stepped lightly on the surface of the lake, creating a circle of ripples visible to the naked eye.

"Follow me."
