After sending away his twin brother, who had taken the drawings from him and was going to make a fortune, Ryan was about to take a short lunch break. Suddenly, Hermione came in from outside the common room and stopped him.

"Ryan, can you accompany me downstairs to the kitchen to investigate?"

"What investigation?" asked Ryan, puzzled. He couldn't remember any professors giving this kind of assignment recently.

"Investigation about house-elves. Hermione explained. "Most of the work in the wizarding world is free slave labor for house-elves, so I wanted to investigate it to determine what the real condition of these house-elves is. After all, I haven't seen a house-elf other than Dobby, who has mental problems, and there is no way to make a proper comprehensive analysis in this case. Thankfully, today Ginny told me where the house-elves at Hogwarts were, and I wanted to take the opportunity to check them out. ”

As long as it's not that vomit, Ryan nodded at this thought. After a little tidying up, he and Hermione went to a bright and wide hallway in the direction of the basement.

Unlike the hallway they used to go to the Potions classroom, the torches were densely packed and decorated with delightful drawings of mostly food. Much more intimate than the underground hallway that led to the Potions classroom.

Halfway down the hallway, they could see a pile of barrels piled up at the end of the hallway. It was supposed to be the legendary Hufflepuff common room, but it wasn't their goal. In front of a painting of a huge silver bowl full of fruit in the middle of the hallway, the two men stopped.

"The silver bowl full of food?" should be this what Ginny was talking about, she said her brothers used to come here at night for supper. With that, Hermione stepped forward and scratched the big green pear. The pear squirmed, eating and laughing, and suddenly turned into a large green doorknob. Hermione grabbed it, pulled the door open, and walked in with Ryan.

This is the kitchen of Hogwarts, a place that Ryan has known for a long time but has never been to before. The whole kitchen is a large room with a high ceiling, the same size as the auditorium above. The surrounding stone walls were lined with glittering copper pots and basins, and there was a large brick fireplace at the other end of the room. It's about the same as he imagined the kitchen.

"Good afternoon, noble sir and miss, what are you here for?" asked a house-elf, who looked a little older, and bowed.

"We've been at Hogwarts for four years, and we learned yesterday that it's you house-elves who usually serve us at school. Out of curiosity, we'd like to know how you work and live in school. I just don't know if it's going to bother you and cause you trouble?" said Ryan.

"Oh, sir, you're so polite, this one doesn't bother. The older-looking house-elf bowed again. "Feel free to take a look and answer any questions. ”

Soon Hermione ran to the side and began to ask about the house-elves, who looked pretty good at Hogwarts. All of them were healthy and wore the same uniform: a tea towel with the Hogwarts crest on it. The elves wrapped the tea towels around their robes. They glanced at the two of them and then lowered their heads to go about their work, only when Hermione went over to ask, the house-elf would stop what they were doing and answer his question earnestly.

Ryan, on the other hand, looked curiously at the four long wooden tables that lay in the huge kitchen, which were now clean. However, during meals, these tables will be filled with food, which will then be teleported to the table above by magic.

After mastering alchemy, Ryan had observed and analyzed many things about Hogwarts, including the dining table. Unfortunately, I only looked at the tables in the auditorium at the time, and I couldn't analyze the teleportation spell on this thing until I saw the corresponding table placed in the kitchen. So now that he had the opportunity to enter the kitchen, Ryan began to observe the tables.

Considering that these tables can teleport to things in Hogwarts Castle, which is said to be invisible, Ryan has always suspected that the principle behind them is likely to be the same as that of the Vanishing Cabinet. If I can figure this thing out, I guess I will be able to grasp more knowledge of space.

"Can you tell me a story about this table?" Ryan asked a house-elf next to him, who introduced Ryan with a proud look, "This table is said to have been left by Hufflepuff, the founder of the school, and was used when our earliest ancestors came here. ”

"Hufflepuff! It's unbelievable that something the school's founder has left behind for more than a thousand years is still functional. Ryan looked surprised.

After learning alchemy, he knew how difficult it was to make magic items that could maintain the effect of a thousand years, for example, the bracelet he made now could maintain the effect for one or two hundred years, and the Valyrian steel weapon could be preserved for a little longer with the advantage of materials. However, the additional enchantment on it can be preserved for five or six hundred years. So Ryan looked surprised when he saw that the magic effect of this very ordinary table could be preserved for thousands of years.

"Of course, the great Huffpa makes a lot of amazing things. At this point, the house-elf looked a little depressed. "It's a pity we lost her favorite gold cup. ”

"Golden Cup?" Ryan thought of Voldemort's Horcrux. Seeing that Ryan was interested in the golden cup, the house-elf gave him a serious introduction.

Legend has it that the golden cup was specially used for drinking, and it could be used to hold the whole school to drink, and at the same time, it could be kept for a year, and the contents were still the same as they were when they were put in and taken out. The only pity is that after Hufflepuff's death, the elves couldn't find the cup.

They had always suspected that a Hufflepuff descendant had taken the Hufflepuff that had been designated to be left in the castle for the house-elves when he was packing up his belongings. Unfortunately, as house-elves, they can't come and go in the castle at will, so they haven't been able to find the cup.

Ryan nodded after hearing this, once he obtained the cup after knowing the original function of the cup, it would be much easier to strip Voldemort's soul tablets. With this bonus, he motioned for the house-elf next to him to go about his work, while he himself began to analyze the magic on the table.

After more than half an hour, Hermione finished her research. And Ryan figured out how these tables worked. He admired Hufflepuff's ability to take advantage of the properties of those ingredients. At the same time, Hufflepuff linked the tables to the magic cycle of the entire castle, which is why these tables have been preserved for thousands of years.

Putting away the small notebook, Ryan nodded to Hermione, who had a somewhat unpleasant face, and then left the kitchen together. Of course, before leaving, they took a lot of snacks from the house-elves.
