After finishing speaking, he didn't wait for Sebastian to reply and changed the topic: "I asked Professor Dumbledore, and he said Moffin Gaunt doesn't know where Voldemort hid Omnius's portrait. However, upon our analysis, it's highly likely that his Soul Artifact is with Omnius's portrait. For instance, Gringotts' vault could very well be one of his Soul Artifact hiding places."
"Seems like he truly is a remarkable person." Sebastian whistled loudly. "To successfully split his soul and create a Soul Artifact. Just enduring that kind of pain makes him extraordinary. Moreover, I gather from what you said that he made more than one Soul Artifact?"
"Yes, his diary is one of the Soul Artifacts," Harry nodded, saying, "According to our guess with Professor Dumbledore, that ring, Marvolo Gaunt's ring, is also likely to be a Soul Artifact he crafted."
"That could be troubling for you." Sebastian's soul rippled like water. "I am just a ghost now and can only watch you fight against that Voldemort—it's a pity, a real pity."
Harry looked suspiciously at the rippling Sebastian, who seemed very excited.
"It seems like you aren't feeling sorry but rather looking forward to it?"
"Of course," Sebastian laughed heartily. "You are taught by me—of course, I mean Dark Magic. Of course, I'm excited to see what kind of thrilling scene it will be when you confront the century's most powerful Dark Wizard, Harry."
Well, he's the type who enjoys watching the chaos unfold.
"I always knew he learned all that Dark Magic from you."
Vivi suddenly turned her head, glaring at Sebastian: "The Three Unforgivable Curses, right? Couldn't you teach him something good?"
"Uh, actually, I also taught him Thunder Explosion and other Evil Curses," Sebastian raised his hand, saying, "and also Fiery Fire, Eye Curse, among others..."
Harry quickly reached out to hold Vivi's wrist, preventing her from raising her hand to cast an Ancient Magic on Sebastian.
"Having a friend like you is such a blessing for him!" Vivi sneered. "If he didn't know Ancient Magic, he would have probably gone mad from the Drilling Curse!"
"But I know that when you learn Ancient Magic, your ultimate emotions gather in that emotional collective," Sebastian laughed. "Besides, when fighting Dark Wizards, how could you do without some Dark Magic? Doesn't Professor Hao Ying often say, 'Know yourself and know your enemy, and you won't lose a hundred battles at all.'"
"Moreover, I didn't realize when you also became so old-fashioned, Grindelwald," Sebastian added. "Clearly, you developed that method of killing all targets within range with a single Avada Kedavra—"
Before Vivi could say anything more, a teasing voice came from behind.
"I never imagined you would have such experiences."
The three of them turned around and discovered that Dumbledore had, at some point, arrived behind them.
"However, I must add that I don't approve of you learning Dark Magic either—at least not before the fourth year. After all, Dark Magic can affect one's mind, and young wizards may find it difficult to handle and could be misled ultimately."
"You're right, Professor," Vivi nodded in agreement.
Sebastian stood up and looked at Dumbledore.
"Are you the current headmaster of Hogwarts?" he said, "I seem to have heard this surname somewhere... Dumbledore..."
"Oh, you might not remember me, Mr. Salu," Dumbledore said, smiling. "But you should remember my sister, Ariana—the young girl with Mormon."
Sebastian looked suddenly enlightened.
"Ah, yes, now I remember." He said, "Ariana Dumbledore, right? I remember meeting your sister when I was looking for a way to control Annie's condition, along with your hot-tempered brother, Abufosi Dumbledore, right? ...How is she? Ariana?"
Dumbledore sighed and recounted the series of events to Sebastian.
After listening, Sebastian looked at Vivi with a complicated expression.
Vivi glanced aside, feeling somewhat embarrassed for having such a scoundrel of a brother.
"I heard from Harry," Dumbledore broke the awkward silence. "Your sister, Annie Saru, is now sealed by Omnius Gaunt in a cave somewhere in the Forbidden Forest. Unfortunately, even after a century, we are still powerless against the Black Magic Curse."
"So all we can do is wait for the right time and find a way to lift the curse to rescue her," Sebastian sighed, lowering his head to look at his ghostly body. "I hope she won't be sad seeing me like this."
"At least you can still be by her side, Seber," Harry comforted him. "That's much better than completely disappearing from her life."
"True, it's just a hassle not being able to eat, but..." Sebastian said with a cheerful laugh, "I'm not like Swedding of Hufflepuff; even if I turn into a ghost, not eating doesn't bother me."
"Speaking of Pabi," Harry said. "Pabi isn't doing so well either; she's turned into a Magic Mage, unable to change back to human form."
