"Think of something good. At least we now know of an enemy in Hogwarts, and he's the kind who hides in the shadows, ready to strike at any moment," Dumbledore said softly, comforting Kayson as he sat beside him.
Kayson, however, ignored him and suddenly fell into deep thought. Soon, he looked up and spoke.
...The problem is... I suddenly remembered something. Alchemy can create objects that are close to perpetual motion, and it can also be understood as life, of course, in the broad sense of life, like plants and flowers. But for such low-intelligence life, perhaps specific programs can be used to make them use various kinds of magic, but making them use Confundo should be very difficult."
Dumbledore also added, "At least he needs an operator… or perhaps Hogwarts has a second one directly, after all, Hogwarts has many outsiders this year."
"Who could it be? It'll be fine once Severus brews enough Polyjuice Potion antidote. But I can only say, this situation isn't very useful. As I said, Hogwarts has many outsiders this year…."
"Pulling out one nail, Tom can seamlessly hammer in another," Dumbledore offered a pessimistic answer.
"We can't just leave it like this, can we? How can you guard against a thief for a thousand days? And now we don't even know who the thief is, so we can't guard against him," Kayson said helplessly.
"My meaning is, now that Nios is an Alchemy puppet, we need to find that other hidden Death Eater, and then we monitor him, but we can't expose him. Just let him live under our surveillance."
"Otherwise, when Tom tries to hammer another nail into Hogwarts's flesh, only Hogwarts's Little Wizardss and other innocent people will be hurt… After all, they need an identity when using Polyjuice Potion, and the original owner of that identity, under their power and methods, will only face death," Dumbledore explained.
"You're right, Dumbledore." Kayson nodded. "Then should we still use Polyjuice Potion?"
"We need to find a time when none of us are sober, like what you're best at… Find a time slot, and the entire Hogwarts will be hungover the next morning," Dumbledore said poetically.
"...…I suddenly think this idea isn't bad," Kayson said dryly, and by the end, he couldn't help but burst out laughing.
After leaving the Headmaster's office, Kayson Ender Teleported back to that small battlefield in the Forbidden Forest. Since he stepped into the magic world, he hadn't fought many proper battles, but the memorable ones all seemed to be in the Forbidden Forest.
This place has some significance.
And Sirius had painstakingly pulled Lockhart out of the wood and was currently debating whether to send him to St. Mungo's or just dig a hole and bury him, which of the two options was better.
However, Lockhart was quickly saved, because Kayson pulled a bottle of bright red Potion from his pocket and poured it all into Lockhart's mouth.
Soon, Lockhart's chest began to rise and fall again, and his unfocused pupils regained their luster.
"How are you?" Kayson asked, squatting beside him.
"It hurts…"
"That's a minor issue, just drink another bottle and you'll be fine." Kayson pulled out another bottle of life-restoring Potion and fed it to Lockhart. With two Potions down, Lockhart could prop himself up with Kayson's help. Seeing this, the latter simply went all out and pulled out another bottle of life-restoring Potion.
After the third bottle, Lockhart could even walk, run, and jump high.
"Thank you this time. Although you didn't have to act this time and were passively used as a living target by the enemy, I still have to thank you," Kayson said, patting Lockhart's shoulder.
"It's nothing… It's just… I never realized before… Hogwarts is too damn scary," Lockhart said, clutching his pounding heart.
"Mm-hmm, I'll send you back. Oh, and keep this a secret, understand?" Kayson said, using a force field to take him back to St. Mungo's, and a minute later, he was back in the Forbidden Forest.
"He won't tell anyone about that, will he?" Lupin asked.
"He deleted that part of his memory himself, right in front of me," Kayson explained. "But what about you now? Your boss is dead. Did they see you?"
Lupin shook his head, "Luckily, I had foresight; no one knew Nios and I came out together. Oh, what did Dumbledore get out of him?"
"Uh…" At this point, Kayson's old face involuntarily flushed, but he quickly relaxed and said directly, "Nios is an Alchemy puppet. He can destroy his own memory storage, so… it's useless." Kayson said helplessly, spreading his hands.
"So, we worked for nothing?" Sirius sighed, sitting on the ground.
"Not entirely. At least Hogwarts has one less enemy…" Kayson stopped there. As for the possibility of another Death Eater or multiple Death Eaters still existing within Hogwarts, he didn't intend to say anything more.
Secrets are best kept quiet. In this situation, saying less is always right.
"That… is not bad. What about Nios then?" Sirius continued to ask.
"Maybe he was eaten by the Acromantula in the Forbidden Forest, who knows," Lupin shrugged indifferently.
"Then I'll go see Harry again and then I'll leave… Wait, can I not leave? I want to stay here and guard him." Sirius's map of Yan was the shortest Kayson had ever seen, almost so short that it couldn't even cover the knife handle.
"Feel free. I suggest you go talk to Dumbledore first. Maybe he can even approve a dormitory for you," Kayson said casually.
"I can already enjoy that wonderful feeling. I'm going to take Harry and find every secret passage in Hogwarts!" Sirius cheered.
