"Then why are you here?" asked Harry Evans coldly.

"The main thing is that the number of times you've been around here for no reason, too often, like the one on Halloween's Eve. Ma Xiu replied of course:

"And by chance, I got an important message from a ghost that a ghost who usually lives in this bathroom has lost a trace of it in the last semester...... I thought, you must have done that, right?"

"After all, if you're going to take Polyjuice decoction all the time, you're going to have to use real Harry Evans, fresh hair, all the time...... So you have to hide poor Mr. Evans in a secluded and dangerous place!"

"The Gryffindor's common room is clearly not suitable, after all, it is too easy to be exposed...... And this washroom clearly fits these boxes. ”

Matthew said as he looked around: "I think Mr. Evans is hiding here by you, I didn't see it, probably put on an invisibility cloak or cast a illusion spell...... Justin Finchrie should have been hidden here by you some time ago...... And Neville and Hermione, who should be here now, too, are hidden!"

"Not bad!" Harry Evans sneered and nodded, "Soon, you'll join one of them." ”

"No, no, no, please calm down a bit. Matthew hurriedly said, "Or, let me guess your true identity?"

"You even know that?" Harry Evans was stunned.

"I've guessed some, it's actually not that difficult...... Matthew said lightly: "It's okay to use the elimination method, the dark wizard from England...... Female...... I'm already very old, otherwise I wouldn't consider using unicorn blood or magic stones to renew my life...... Very strong, with magical powers that are not inferior to, or even better than, Headmaster Gellert Grindelwald......"

“...... There are only a few people who meet all these conditions, right?" Matthew said calmly, "Or rather, there is only one person in the history of British magic—"

"Morgana...... Or rather, Morgan Le Fay!"

......

"Succubus and Incubus, although they are called differently, many wizards think they are the same creature!" Matthew said calmly, "except that the former is a female and the latter is a male...... They are all in dreams, in the form of human females/males, absorbing the essence of the opposite sex. ”

“...... Succubi, as for the Muggles of ancient times, sometimes mistakenly called them 'leprechauns'...... This is also the meaning of the name Morgan Le Fay in Muggle legend for Morgan Le Fay, the Black Witch Morgan. Matthew paused for a moment:

"The Grand Magister Merlin and the Black Witch Morgana, both of whom possess the blood of the Dream Demon/Succubus, and in the time they lived, the magical creature of the Dream Demon/Succubus had been extinct in the wizarding world......"

"So my guess is that in the 6th century, after the duel that decided the fate of English magic, Merlin defeated Morgana, but he remembered that they were of the same kind, the same half-blood dream demon/succubus, and did not kill her, but somehow sealed her!"

"It wasn't until the elven rebellion of the eighteenth century that Merlin died unexpectedly, and his legacy was lost and never found for hundreds of years...... So I guess that maybe because of Merlin's death, his seal also lost its effect, and Morgana stole Merlin's inheritance and went into hiding!"

"Don't forget, Merlin's legacy contains a 'Philosopher's Stone...... So I think that for hundreds of years, Morgana has been relying on that Philosopher's Stone to keep her alive and regain her strength......"

“...... But the Philosopher's Stone is a consumable, and it will run out of service one day...... So, without the Philosopher's Stone, Morgana also lost her means of life, and because of this, she set her sights on Hogwarts, which is home to both a living unicorn and the only remaining Philosopher's Stone in the world......"

“...... That's what happened at Hogwarts!"

"Yes, honorable Lady Morgana!" said Matthew as he bowed respectfully.

"Harry Evans" did not deny Matthew's words, she just looked at the boy in front of her quietly, and a smile suddenly appeared on the corner of her mouth.

"I really didn't expect that a first-grade boy from a Muggle background would actually know my bottom clearly. She whispered, "I feel a little sorry more and more, if I kill you here, it would be a pity......

"I'm really upset, Lady Morgana!" Matthew said with a look of regret, "I'm talking to you so openly and honestly, and you're still thinking about killing me!"

"Oh?" Morgana, disguised as "Harry Evans", looked at Matthew in dismay.

"Actually...... I'm here to talk about conditions......" Matthew raised his head: "Or, conditional surrender!"

As he spoke, Matthew raised his hands and gave a French military salute.

"Interesting...... Morgana looked at Matthew with interest, and a smile appeared on the corner of her mouth: "What conditions?"

"Let them go, Neville Longbottom and Hermione Granger...... And Harry Evans, if you can...... And, of course, my life!" Matthew said quickly.

"Your appetite doesn't seem small, Mr. Wakefield!" Morgana shook her head with some regret, "I'll let Longbottom go, or I can consider sparing your life...... But I'll at least kill Hermione Granger and have her body found by someone else......"

“...... I'll have to cause even more chaos at Hogwarts before I can help me find the Philosopher's Stone lurking on the Hogwarts campus!"

Matthew's hands still didn't go down, and he continued:

"I'm not done with my terms, Ms. Morgana...... For the price of all this, I can help you find the Philosopher's Stone!"

"What?" said Morgana, the black witch, whose face changed suddenly.

PS: Morgana is a character who appeared in the original Harry Potter books, and she appeared very early. She is the second chocolate frog drawing that Harry himself has collected. In the original book, the first one was made by Dumbledore, Harry himself, and the second one was Morgana, which Ron opened, and then said that he already had six and gave it to Harry. It's just that the translation in the original book is "Morgana", and of course I think Morgana's translation as "Morgana" is more familiar.
