After hearing Draco's thoughts, everyone couldn't sit still.

Harry and Draco quickly became close friends with the twins. Unlike their peers like Ron, these eight-year-old twins weren't as childish. Although lively, they also looked after their younger brothers like adults. This made Harry and Draco, who had only interacted with children their own age, envy Ron immensely.

Seeing the sun gradually getting hotter, Narcissa was worried that the children would get sick from the heat, so she called them to the newly opened toy room. As soon as the children entered, they felt the cool breeze on their faces, which was very comfortable and took away the summer heat.

They happily explored the treasure room, where the dazzling array of toys was dazzling. Ron saw a black square on the table. Curious, he picked it up and pressed the red button on it. A few words slowly appeared on the white screen opposite the sofa.

"Doraemon?" Ron read aloud. At this moment, the tall black rectangle beside the curtain suddenly emitted music, which not only scared Ron, but also attracted the children who were exploring around.

"Wow, what is this?" George sang.

"Magic magic?" Fred said.

Percy was also curious, but being a very polite person and thinking he was the most senior among them, he was too embarrassed to ask. Ginny, on the other hand, hid behind Percy out of curiosity, too shy to speak.

"Wow, what is this, Draco?" Ron didn't have so many thoughts and asked casually.

"It's the TV." Draco pointed above his head again, "This is the air conditioner, they are all Muggle things." This was something Harry said accidentally and Lucius secretly wrote down. I don't know how he tinkered with it, but he actually installed it successfully for Lucius.

It was said that a huge amount of money had been spent on such a Muggle facility. After all, they seemed to need something called electricity. Lucius also installed air conditioners, refrigerators, and other amenities in the manor. Even Narcissa, after using them, thought that Muggles really enjoyed themselves.

"Muggle stuff? Really? How does it work? Is the electricity you just mentioned the same kind of lightning we summoned? And more..." Arthur just came here with Lucius to see the children, and went next door to discuss business. Merlin knew that Malfoy actually had business to discuss with him?

He wasn't trying to belittle himself, but he really couldn't think of any business the Malfoys had that he could help with. As soon as he reached the door, he was drawn in by Draco's words. He was incredibly obsessed with Muggle items, so how could he even remember what business it was after hearing all this?

Molly, who was beside him, quickly grabbed her husband by the back of his collar. "Arthur!" This idiot always did this.

"Oh, I'm so sorry. I was rude." Arthur came back to his senses. For the first time, he looked at Lucius Malfoy without any prejudice. Could it be the so-called business... He looked at Lucius expectantly.

Lucius felt a chill at the contrast, then nodded reservedly, "As the Director of the Misuse of Muggle Artifacts Department at the Ministry of Magic, I'm sure you won't be able to refuse this offer."

It's said that the person who knows you best is your mortal enemy. Lucius knew Arthur's curiosity about Muggle things, and also knew that he had secretly modified many Muggle items.

Lucius planned to introduce some Muggle things into the wizarding world. The more he learned about Muggles, the more frightened he became. Muggles might be weak, but their creativity and threat had reached a level that Lucius could not ignore. He had to admit that the Dark Lord might be right, but he was too radical.

Lucius had no great ambitions, aside from his family and the glory of the Malfoy family. He didn't want to arouse Dumbledore's vigilance; that wouldn't be good for him, would it? But Cissy thought, Cissy possessed ambition, skill, and determination comparable to any wizard, but she had always been content to be a good wife and a good mother.

But she wasn't just his wife, Draco's mother; she was also Narcissa Black, and she had to be herself first. The arrival of Draco's system not only gave them a healthy, proud little dragon, but that night after reading those books, he had seen, in his lover's small probing attempts, in those previously calm eyes, the flame of his wife's unwillingness as a woman, a flame that ignited her ambition, so bright that he felt as if he were being burned.

But ambition is never a bad word, right? Especially for a Slytherin.

So, he had to be the man behind Cissy, right? He would make the wizarding world slowly take the Muggles they had always looked down upon seriously, and he would leave a way out for Cissy, whether she succeeded or failed. The two of them understood each other tacitly, one in the open and the other in the dark.

Lucius, with a genuine smile on his face, led the Weasleys to the next door, where various Muggle things were kept. As for what he was thinking, only Narcissa knew.

----------------------------------

The adults' affairs had nothing to do with the young children. Several children squeezed onto the sofa, which Lucius had custom-made for the two children. Sitting there felt like sinking into a cloud. Ron sighed comfortably.

"This sofa is so comfortable. It's great to be rich." The Gemini and Ginny nodded in agreement, and even Percy had some envy in his eyes.

"If my parents succeed in cooperating with your parents, believe me, you will be able to enjoy these things before long." Draco and Harry knew that the adults seemed to have some business to discuss. Although they didn't know what it was, they should never doubt a Malfoy's ability to make money.

"Really?" Ron was extremely surprised. His parents didn't say they wanted to do business with the Malfoy family. That was Malfoy, the walking gold galleon of the wizarding world.

George and Fred were also shocked. After all, they were not as thick-skinned as Ron. They knew that their father was always complaining and they found Lucius Malfoy's arrogance annoying and wanted to punch him. Even Percy pricked up his ears. He didn't think there was anything wrong with his family, but he saw his parents' hard work and wanted to make a name for himself and share the burden with them.

"Of course. Malfoy..." Draco was interrupted by everyone before he finished speaking: "Malfoy can do it!" Several children looked at each other and couldn't help laughing, and their relationship became more harmonious.

Ron shoved the remote control (according to Harry) into Harry's hand and said, "Harry, show us what's so magical about this Muggle thing. I can't tell the difference between all the little buttons."

He'd been so caught up in the music that he'd accidentally clicked something and the screen froze. At Draco and Harry's behest, they'd drawn the curtains, leaving only the screen to illuminate, so it wasn't too dark to see anything. They'd all huddled together on the sofa, ready to watch this Muggle thing.

Ron had originally wanted to see the strange blue magical creature, but Harry suddenly remembered something and whispered to Draco about showing them a treasure. It was all very mysterious, and they could only vaguely hear something in the study. Draco took a black pancake-like object (a disc) and placed it in the box under the TV.

Harry also placed tissues next to everyone, and amidst their bewildered expressions, he said meaningfully that they would be useful. Ron suddenly felt an itch in his fist for some reason.

Harry looked at everyone's expectant faces and exchanged a meaningful look with Draco in the darkness. A slightly sinister smile flashed across Harry's cute little face, but it was fleeting and no one noticed. "Then I'll start," Harry said softly.

He pressed the button, and a few large words that no one recognized flashed on the screen - Demon Slayer: Kimetsu no Yaiba the Movie: Mugen Train.

Ron and the others were a bit confused by the beginning. Why are this person's eyes so big? Even the portraits aren't this abstract. What is a ghost? Is it the same as a vampire? These people's names are so hard to pronounce. Yeah, this person looks like an owl, hahaha. Hahaha, is this pig-headed man some kind of magical creature?

But as the story progressed, the discussion gradually died down and everyone watched intently. Even Harry and Draco, who had seen it once, were glued to the screen.

I will do my duty! I will not let anyone here die!

Being strong is not just a word that refers to the body, because helping the weak is the duty of those who are born strong.

Aging and death are precisely the beauty of the brevity of human life. It is precisely because of aging and death that we are endearing and noble.

Have I done well? Have I done everything I should do and fulfilled?
