Harry Potter, the savior of Night City

"Well then, we can begin." Harry looked at Voldemort, whose eyes were darting around, still thinking about some wicked little scheme. He pulled out his wand and bound Voldemort tightly, leaving only his head sticking out. "Tell me the location of all your Horcruxes."

"I..." Voldemort wanted to struggle a little longer, hoping to gain some more benefits, but as soon as the thought arose, he felt a palpitation coming from his heart. Voldemort was at a loss, laughed angrily, opened his mouth, and wanted to say something unrelated, but the feeling in his heart threatened him at all times. Oh well, he might as well live one day at a time.

"The first Horcrux, that diary, has already been destroyed by you. The second..."

"Wait a minute," Dumbledore's voice rang out. He looked at Voldemort. "You should know about the anomaly with that diary, right? How can you be so sure that your other Horcruxes won't experience the same thing?"

"That's your business," Voldemort said. "Of course I know what happened to the diary. I even dealt with the thing that caused my Horcrux to change. It must have been a god. He said that if I believed in him, I could live forever, but I didn't. After that, he never spoke to me again. That's all I know."

"You're so afraid of dying, yet you haven't gone into any of those wicked ways?" Harry asked.

"What kind of god is this? He doesn't deserve my faith. I am even more noble than a god. If I hadn't fallen into your hands, Merlin would have bowed down to me sooner or later."

(Outside the world, a green sphere of light, which consisted only of will and could not even corrupt the life of this world, watched this scene speechlessly, and casually lit up a few words in the void: "Did you miss us?")

"...Go on," Harry said, covering his face.

"The second Horcrux, Nagini, my snake; the third Horcrux, Ravenclaw's tiara; the fourth, Hufflepuff's cup; the fifth, Slytherin's box of jewels; the sixth, the Gauntlet ring, with the Deathly Hallows Resurrection Stone set in it. That's all."

"And the seventh one?" Dumbledore said, staring into Voldemort's eyes.

"What, the seventh one?" Voldemort looked back with a puzzled expression.

"Ever since you were a student, I've known you have an obsessive fascination with the number seven. So, given your habits, it's impossible that you only created six Horcruxes. So, where is the seventh one?"

"I only made six." Voldemort shifted his tightly bound body, lying down in a more comfortable position. "Yes, I did want to make a seventh, but that stupid woman ruined it halfway through, and it's been half-dead for over a decade, hasn't it?"

"Is that so..." Dumbledore turned to look at Harry, his eyes questioning.

“He wasn’t lying,” Harry said. “The curse of the oath wasn’t triggered, or he would have been in hell just now.”

"Alright, then, it's time to settle accounts." Dumbledore looked at Voldemort again. "As my student, you have defiled Hogwarts and the relics of the founders. Based on that alone, I could kill you right now, but that would be too wasteful." Dumbledore was expressionless, but anyone could sense his anger. After all, only Voldemort could make him want to torture a prisoner.

"I suggest turning him into a teaching tool for Defense Against the Dark Arts," Grindelwald said. "The Dark Arts studies at Hogwarts are indeed progressing well, but they still lack practical experience. With a guy like him who's quite capable, the students' strength will definitely increase, and..."

"And you want to be the Defense Against the Dark Arts professor next year, right? Rejected. Go back to where you belong." Dumbledore didn't even glance at him.

"Don't be so heartless, you know my teaching abilities."

"I don't want my students to grow up to be a bunch of crazy people who were purged by Avada Kedavra."

"That's insulting! I'm not that crazy person."

...

Harry turned to look at the two of them and sighed. "How about I take it back to Azkaban? It wouldn't be bad for it to be an AI that answers students' questions."

"Ai, what is that?" Dumbledore asked, completely bewildered.

"Isn't AI a dangerous thing?" Grindelwald, who had been to Night City, also turned to look at Harry.

"That's dangerous in Night City, and when I say AI, it's actually a pseudo-AI centered around this guy."

"Wait a minute, so what exactly is AI?" Dumbledore's curiosity was piqued.

...

The three argued incessantly. Voldemort, who was sitting on the table, turned his eyes to the wand that Grindelwald had casually put down. He twisted his body and crawled toward the wand like a caterpillar. One step, two steps, he was getting closer and closer to the wand. Voldemort even stuck out his tongue to reach for the wand, but the wand was picked up by Grindelwald right in front of him.

"Looks like you're still not being honest," Grindelwald said, pointing his wand at Voldemort. "Crunch in the Heart."

The red spell struck Voldemort, and excruciating pain instantly spread throughout his body. Voldemort, whose soul was already unstable, was tormented in this way, and before he could even let out a wail, his eyes rolled back and he fainted.

"He got off too easy," Harry said. "Well, I'll take him back. As for the Horcrux, you can handle that, Dumbledore."

"Yes," Dumbledore nodded, but then looked at Harry. "Harry, just to be on the safe side, I'd like to ask you, Harry, have you ever been in a state of telepathy with Voldemort?"

Harry felt a chill run down his spine. If it weren't for the fact that even his skin was artificial, he probably would have gotten goosebumps. "I'm telling you, old bee, you're gay, but I'm not. If you keep causing trouble, I'm blowing up your office right now."

"That's not what I meant." Dumbledore's face darkened slightly. "What I meant was that there's a connection between Horcruxes and their master souls. Your mother's curse did indeed shatter Voldemort's soul, but some of his soul might have entered you, turning you into a living Horcrux, so..."

"Ah. I see..." Harry listened to Dumbledore's explanation and understood. So that's what the voice in his head meant when he traveled from Night City to this world: "Excess soul fragments detected, initiating elimination." The soul fragments belonged to Voldemort...

"No, I can assure you, I have absolutely nothing on me. I've checked with soul-detecting magic, and it's spotless," Harry said.

"Is that so? Then it's alright." Dumbledore's voice relaxed a bit. He hadn't expected that the dark cloud hanging over the magical world, caused by this guy, would be resolved so hastily...

"I still have quite a few Galleon keys in my drawer. Take them all. Your contributions to the wizarding world, though I'm reluctant to admit it, far exceed mine..."

"Bang, bang..."

Before Dumbledore could finish speaking, there was a knock on the headmaster's office door.

"Please come in."

With a creak, the wooden door opened, and Fookiena's obese body appeared outside.

"Cornelly Fudge, what do you need?" Dumbledore asked, looking at him expressionlessly.

"Nothing much, just wanted to see the champion of this year's semi-finals, our savior," Fudge said, walking into the principal's office. "By the way, what's that?"

He pointed to Voldemort, which Harry was holding.
