Harry spent so long in the Magic Mobile Phone Shop because he and Hermione were working together to try and get clues about the basement from Hagrid.
They reasoned that if Professor Lupin could access the basement, then Hagrid, as Director Lorne's good friend, must know what was inside.
As for Professor McGonagall, Harry believed it was necessary to keep some things from his superiors, and he also had many things he would tell Ron but not Percy.
" Hagrid, give up. Even Professor McGonagall told me what you've been trying to hide from me. I thought we were friends, and that friends should be able to talk about anything."
Hagrid, holding his phone in the cabin, exclaimed, "What? Impossible! Professor McGonagall would never tell you that!"
Harry pointed to the Magic Mobile Phone and said to Ron, "See? I told you Hagrid would know."
Ron's expression was one of absolute certainty. " Director Lorne can't hide this from us this time."
But they soon realized that Hagrid wasn't telling them the same thing.
"You must be joking with me. How could Professor McGonagall possibly tell you that Sirius was Potter and Lily's Secret Keeper?"
"What are you talking about? What do you mean by 'Secret Keeper '?"
Hagrid suddenly fell silent on the screen. After about ten seconds, the message Hagrid had just sent disappeared, leaving only the line "The other party retracted a message."
Hermione suddenly felt a little guilty. "Let's not try to trick Hagrid like that again. Even if we find out, we won't feel good about it."
Harry nodded, but his mind was on the message Hagrid had sent him on Cuckoo.
Potter and Lily are clearly his parents, so how could Sirius be related to them?
Harry knew that Sirius was a Death Eaters had escaped from Azkaban, and that his ultimate goal might be to kill him. From Hagrid's words, it seemed that his parents' deaths were also related to him.
"Perhaps we should try contacting the Detective Club," Ron said, looking at Hermione. "You know, they have access to all historical records."
As the trio discussed their strategy, a large group of people suddenly poured out of the basement. They were all seventh-year students, chatting and laughing together, much like Harry when he first arrived at Hogwarts.
Harry glanced at Professor Lupin, who was walking at the very back of the crowd, and had a feeling that the other man must know something.
The seventh-year students crowded around Director Lorne, blocking his way. Ron craned his neck to look, but Harry, in a bad mood, didn't go forward.
Harry quickly composed himself. "I'm fine now. We'll figure something out when we get back to Hogwarts. Let's go see what they're up to now."
With closing time fast approaching, the students on the second floor began to come downstairs one after another as the trio crowded to the front.
Lorne pulled out several large boxes from under the table, filled with neatly stacked, square-shaped stone slabs. Harry immediately noticed that the shape and arrangement of the slabs seemed familiar.
The business card of mining tycoon Mr. M! The keepsake that Director Lorne gave him.
Harry pulled it out from the innermost part of his pocket, and sure enough, the stone tablets were exactly the same as the ones on it. It turned out that Director Lorne was running a mining operation in the Muggle World for these stone tablets.
The moonstone, gleaming and pure white, and the garnet, crystal clear and blood red... The seventh-grade students registered one by one, and each of them took five stone slabs and left.
Harry tried to make way for them, but suddenly realized that a crowd had gathered behind him as they came down from the second floor, including Professor McGonagall.
Looking at the crowded scene in the store, Lorne suddenly felt that this was a good opportunity.
He called Lupin to the front desk to help supervise the seventh-grade students' registration and distribution, while he himself stood on the platform again, shouting at the top of his lungs, "Students, please do not crowd, please leave in an orderly manner to prevent stampedes--"
Lorne drawled out his words as he scanned the students, deliberately pausing for a moment to attract their attention. "Of course, those interested in the Magic Mobile Phone can stay for now. Next, I'll demonstrate how to update a game."
"Update the game?" Goyle, who was sitting in the audience, turned around sharply.
"Which game?" Crabbe next to me had already raised his hand to ask.
Lorne held up three fingers. "Naturally, it's three games. To be precise, even Cuckoo will receive a small update."
"Finally updated!" Ron, the psychic Magic Mobile Phone user, shouted, raising his arms. "Do you know how long I've waited?"
Lorne continued unhurriedly, "Please look at my hand. This is a storage device with a capacity of approximately thirty minutes of footage. The game's production and updates are inseparable from it."
"It can not only scan the images, sounds, and movements you imagine, but also record real-world paintings and music. With it, you have the most basic tools for making games. Of course, how to make games is a very vast subject, and even I wouldn't dare say I'm completely proficient in it. But I'm sure that in the future, more and more people will choose this path and share their interesting ideas with all wizards. It could be you, it could be you, it could be you."
Lorne randomly picked three students and pointed them out, immediately eliciting a burst of screams.
"Many students might be wondering, why open a Magic Mobile Phone shop next to Hogwarts? Besides Hogsmeade Week, there aren't many people around, and they're mostly poor students who can't afford Magic Mobile Phone."
"I would answer them—yes! I opened the Magic Mobile Phone shop here simply because it's next to Hogwarts. I want our Hogwarts students to know that times are changing, history is progressing, and the Wizarding World is currently undergoing unprecedented changes. The arrival of the Magic Mobile Phone will not only bring us many jobs, but even the most basic perspectives and lifestyles will change."
"..."
Lorne became more and more excited as he spoke, even forgetting that the semester was not over yet. He acted as if he were being brainwashed in the Magic Mobile Phone store in Diagon Alley until he saw Professor McGonagall in the crowd and snapped back to reality, immediately returning to his business.
"Now, our store will be holding a grand game update ceremony. All I need to do is insert this storage device, which integrates the latest content, into any phone, and all phones will be updated in real time. Are you ready? Those of you with Magic Mobile Phone can keep an eye on your phone screens."
"Three--"
"Two--"
"One!"
With the storage component in his left hand and the Magic Mobile Phone in his right, Lorne seamlessly connected the two devices amidst everyone's attention. Immediately, a student staring at the Magic Mobile Phone shouted, "It's real! The game popped up an announcement!"
Lorne smiled contentedly, "Happy Halloween everyone! Once you're back at Hogwarts, if you have any questions about life, studies, or employment, feel free to come to the General Affairs Office on the second floor of the castle. The General Affairs Office will be happy to serve every teacher and student."
