Mastering Lightning from Hogwarts

"A Death Eater has an intelligence source in the Order of the Phoenix? Who is it?" Dumbledore, having heard Snape's words, finally confirmed some things and continued to question Snape.

"I don't know, it could be anyone. They can't be exposed like this anymore. The Dark Lord will always find an opportunity. Maybe next time, or the time after that, he'll succeed. I know he won't give up." Snape's voice trembled, but he still told Dumbledore everything he knew.

Immediately afterwards, Snape seemed to have made some determination, and the scales in his heart tipped irrevocably to the other side. He pleaded with Dumbledore, "Hide her, hide them all, I beg you!"

"And what are you prepared to offer in exchange, Snape?" Dumbledore looked at Snape with calm eyes and said softly.

Having made his decision, Snape's face changed from the previous struggle to a slightly dazed expression, and then he said softly, "Anything!"

Seeing that Snape had finally made up his mind, Dumbledore felt a weight lift from his heart. He nodded and said softly, "Remember your words today. I will find a way to protect Lily and her family. If there are any movements on Tom's side, remember to notify me. You know how to find me."

Snape now seemed to be drained of all strength, nodding numbly, and then said, "The Anduin you just mentioned, is that the bastard who saved Sirius Black that day?"

Dumbledore nodded and said, "Indeed, and he was also sorted into Slytherin, but his position is much firmer than yours."

"A Slytherin? Well, maybe my initial choice was wrong. Help me give this to him, consider it my thank you gift." With that, Snape took out a bottle of potion from his怀中 and handed it to Dumbledore.

"It seems you're not entirely beyond redemption. Perhaps one day you can express your gratitude to him face to face." Dumbledore, seeing the change in Snape's position, finally showed a hint of a smile and accepted the crystal bottle Snape handed over.

And Anduin, whom they were talking about, had already fallen into a deep sleep.

The next day, James took Anduin to retrieve his luggage from Sirius' house. With the Undetectable Extension Charm, Anduin could now carry all his belongings with him. James was shocked by the changes in Sirius' house. He knew Sirius' house was a mess, and now seeing the clean and tidy house, he could hardly believe his eyes.

"So, you're saying you helped clean up Black's place? That's really amazing." James repeatedly refreshed his impression of Anduin.

Anduin didn't think it was a big deal. Then, he and James went to St. Mungo's Hospital for Magical Maladies and Injuries to visit Sirius. That guy was never idle, and he wouldn't stay in bed obediently. If James and Anduin hadn't visited, he wouldn't even have stayed in the hospital room.

Seeing that this guy still had the energy to jump around, James and Anduin were relieved. After saying goodbye to Sirius, they returned to the Potters' residence before lunch.

"Anduin, during the time you're staying here, if you need any help, just tell us. After all, you've helped us so much." During lunch, Lily looked at Anduin, who was teasing little Harry, and said with a smile. James nodded in agreement.

Hearing Lily say this, he felt a little embarrassed. He smiled and said, "I'm already very satisfied with all the care you've given me. There's no need to be so polite."

Seeing Anduin say this, Lily felt even more guilty. After thinking for a while, she said, "Right, aren't you very interested in the amulet and protective magic I gave you? I can teach you as much as possible during this time. You can also freely browse the Potter family's library. I think you can find what you want there."

Upon hearing Lily say this, Anduin was overjoyed and said with a beaming smile, "Really? That's great! Professor Flitwick has always told me that you are his most proud disciple. I happen to have many questions I want to ask you."

Seeing Anduin so eager to learn, Lily couldn't help but think of her student days. Muggle-born, diligent, and a strong desire for knowledge, Anduin's qualities were very similar to her own. Looking at Anduin's black eyes and black hair, as well as his Slytherin background, she was reminded of another former close friend. Lily was lost in memories for a moment.

At this moment, Harry's untimely cry interrupted Lily's thoughts. She looked at little Harry, and a strong sense of love reappeared in her eyes.

After lunch, after putting Harry to sleep, Lily took Anduin back to the underground safe house where they had fought before. It had been cleaned up, most of the clutter had been removed, and the empty room made it a suitable practice classroom.

After standing in the room, Lily said to Anduin, "I've seen your Levitation Charm and Severing Charm before, and they were used very wonderfully. You must have spent a lot of time practicing the spells. If you want to practice spells, you can do it here. I can also be your sparring partner, and you can ask me any questions, as long as I can help you answer them."

Hearing Lily say this, Anduin didn't stand on ceremony. After thinking about his spell learning during this time, he said, "I've recently found that some spells are difficult to master when practicing them, such as the 'Shield Charm'. Either the spell isn't successful, or the Shield Charm cast isn't strong enough, and it's not even as good as the Barrier Charm I learned before. What's going on?"

"What? You've already started practicing the Shield Charm? That's not a spell you can master at your age. Even many Aurors who have just joined the Ministry of Magic can't necessarily use this spell proficiently." Hearing Anduin throw out such a difficult question at the beginning, Lily couldn't help but look at Anduin in a new light. It should be known that her magical attainments are also not small, but she gradually mastered the Shield Charm after her fifth year. Other students may not be able to successfully cast it once even after graduation.

"So, is it a problem with the difficulty of this spell? But I don't think its incantation is complicated?" Anduin asked puzzledly. In fact, not only the Shield Charm, but also the 'Undetectable Extension Charm', 'Patronus Charm', 'Disillusionment Charm', etc., he had difficulty casting successfully in one go, but he confirmed that there was no problem with the spells he chanted.

Hearing Anduin say this, Lily knew that he must have a certain understanding of the Shield Charm, so she said, "Like this, you use the Shield Charm once, and I'll see where the problem is."
