Before Hermione came to him, Darren hadn't thought that after experiencing the myrtle in the prefect's bathroom, she would take the initiative to discuss diving with him again so soon.

"Oh, it's a bit cold in the lake in a wetsuit in this weather!" In the face of her request, Darren was a little embarrassed, because of specific heat and conduction, the temperature of water tends to rise slower than air, and the temperature under the water is lower, "hot rises, cold falls", he is worried that after diving into the black lake, Hermione's body will not be able to stand it, although the body fat rate of women is actually higher than that of boys, and they are theoretically more frost-resistant, but the loss is also large......

"Didn't you say you could keep warm?"

"It's a dry suit that keeps you warm, but I ......didn't finish talking about it last time," Darren didn't continue.

"Then you can move on."

"Go on......" Hearing this, Darren suddenly felt a little dry mouth, "Are you still going there?" But myrtle ......"

He looked at Hermione, who blinked with wide eyes and a smile on his lips, "yes, I've found a good place, it's definitely the right place!" ”

That night, Hermione led Darren up the shifting staircase until he reached the eighth floor, stopping and walking down the hallway.

"You said you want me to explain how to wear a wetsuit, what are you doing here?"

"You'll know when you get there," Hermione pulled Darren in front of her, not answering his question directly.

Following her, his brown hair swaying gently with that graceful figure, and a faint fragrance in the air, Darren stopped talking, he really wished he could go on like this!

"Alright, this is it!"

But that can only be a dream, Darren hurriedly concentrated, looked around, and saw that in front of him, there was a section of white wall......

White wall, white wall? White Walls!

Darren turned her head to Hermione, and she smiled and said, "The house-elves told me when I went to look for Dobby and Shining. ”

"Oh? House-elves? Darren repeated, it seemed that Hermione had a good relationship with them, and if she still adhered to the previous S-P-E-views, I am afraid that she would not be able to do this.

"Yes," Hermione said with no notice of Darren's strange appearance, still full of curiosity, "they call it 'Come and Go House' or 'Room of Requirement'!" It is said that this room can only be entered when one really needs it, but when it appears, it is always furnished to the needs of the person who asks for help! She turned her head to look at the tapestry behind her, which depicted Silly Barnabas teaching trolls to do ballet, "Yes, this is it." ”

Hearing the name of the "Room of Requirement", it dawned on Darren that this was the place, indeed, if it really worked as its name suggested, it was indeed a good place to practice all kinds of exercises, and it was absolutely secret.

He had been interested in this famous room before, and had searched in Hogwarts Castle, but because he had no impression of the specific location of the room, he didn't even know which floor it was on, only that he had to go back and forth three times, so it was really difficult to search in the huge castle.

And in the history of thousands of years, many teachers and students have left a variety of secret rooms and secret doors for various purposes, which are endless, and many of them will give a bad impression to people who don't know what to do and open casually.

In addition, he doesn't have any need for the "Room of Requirement", although there is a Voldemort's Horcrux in it, the Ravenclaw crown, but there is no need to rush, that thing will not run away by itself, and then he has been busy with various things, and slowly forgot about it, but he didn't expect to be brought by Hermione today.

"Dobby said to walk through this wall three times and concentrate on what we need," Hermione pulled Darren as she walked to the window at one end of the white wall and turned back to the one-man vase on the other side, whispering, "We need a place where we can learn how to put on and use a wetsuit, well, to be able to practice, to have a changing room!" Suddenly, she frowned, "Keep it a secret so that no one else finds out!" ”

Darren......

When they turned for the third time, suddenly, Darren saw patterns begin to appear on the wall, which continued to extend and bulge upwards and connect with each other, and a moment later, a large door appeared on the wall that had been blank.

Darren stopped Hermione, stretched out his hand, took the brass handle on the door, and with a slight push, the door opened, and they walked in, and inside was a spacious room, surrounded by torches, and in the middle of the room was a large swimming pool, and the water in it was crystal clear, and on one side of it there was a fan-shaped staircase for people to walk on, and half of the bottom of the pool was sloping, allowing the water depth to gradually transition from shallow to deep.

In addition to the central swimming pool, there is a row of sprinklers on one side of the room that can be used to wash the body, and snow-white towels hang from the partitions between them, and next to that row of sprinklers, there are several small fully enclosed rooms with the words "changing rooms" written in the doorway.

…… Well, it is worthy of the "room of responsiveness", and sure enough, "responsiveness"!

Darren looked at the room in amazement, this room was real and wonderful, he couldn't understand the rules of its operation at all, maybe it was a room that combined the Traceless Stretching Charm, the Dementor Mind and the Large Powerful Transfiguration Charm, or maybe it was simply some kind of spatial magic that could be connected to countless pocket spaces?

Hermione was also amazed by the "Room of Requirement", looked around, and after seeing the locker room, she also opened the door and went in, taking advantage of this time, Darren took out the wetsuit and set it up by the pool, by the way, although the drysuit was warm, it was too troublesome to use and maintain.

"How's it going, okay?" Darren was busy with his work when he heard Hermione's voice behind him.

"Well, I'll look at this valve......" said Darren, turning his head as he caught a glimpse of a pair of white, tender bare feet, with tiny toes spread and treading on the smooth floor.

He looked up and saw that Hermione was standing in front of hermione, who had changed into a one-piece bathing suit, I wonder if it was because of the locker room, this time she was much more generous, no longer a little shy like last time, leaned forward slightly, and lowered her head.

Darren's eyes scanned up and down, his well-proportioned and slender figure matched with a decent plain swimsuit, perfectly outlining the gentle curves of his body, and his gestures were full of youthful vitality; Against the backdrop of long brown hair, the soft skin is fair and delicate, as if it is congealed, which makes people want to touch it to experience the smoothness; The brown eyes shone brightly, and the handsome and elegant face and cheeks were healthy and rosy, and they were particularly beautiful and amazing in the light of the fire; Playful lips are slightly upturned, moist and full, like delicious grapes, full of seduction......

Although the torches burning around the "Room of Requirement" are vigorous, they still fluctuate in light and shade from time to time, adding a strange thrill to Hermione's beauty!
