"What do you mean by what you just said?"
Seeing Professor Snape change back to his previous icy self, Lucas shrugged and returned to his seat.
"Professor, don't you really wonder what magic Lily Evans used?"
"As far as I know, none of the currently known protection spells can compare to the one used by Lily Evans."
Lucas brought up the name Lily again, but Professor Snape's eyes were no longer disturbed.
Probably because of the success of the Legilimency attack by Lucas just now.
Now he is like a hedgehog, firmly defending his heart.
~heh~
Snape let out a sneer.
"Although the Potter family is not one of the 28 sacred families, it used to be an absolute pure blood family."
"In such a family with a long history, there are always some unknown secret books."
"That's right!" Lucas nodded.
"But why haven't I heard of such a thing in the equally old Malfoy family? Last summer, Draco and I went to 12 Grimmauld Place."
"The Black family?"
"Yes, as the oldest pure-blood family, Madam Black has little impression of such magic."
Lucas didn't speak anymore. Instead, he snapped his fingers and called the house elf to his side.
"Little master, Shana follows your orders."
"Go get us two desserts, mine can't be too sweet.
"Okay, little master, please wait a moment."
Shana's figure just disappeared and Professor Snape's voice came immediately.
"Tell me what you know, you must have already investigated it clearly?"
Another quaint book appeared in front of him.
Reading the title of the book, Snape asked suspiciously, "Why have I never seen this book?"
"Look at the content first, especially the part about the curse of blood sacrifice."
Professor Snape opened the book dubiously.
It is easy to find the relevant introduction of the mentioned Curse.
"The user must be full of strong love... the loved ones who are guarded will not live to be fifty years old?"
Reading it aloud, Professor Snape's expression froze, and the distress in his eyes showed for a moment.
"Where did you get this book? Didn't you say that no one knows what magic Lily used? Then what is it?"
Professor Snape raised the book in his hand and asked sharply.
"Don't be impatient."
Lucas appeared suddenly, raised his hand and pressed Professor Snape's shoulder.
"The next thing is my personal secret. If you are willing to make an unbreakable vow with me, I will tell you."
"If you don't want to, then today's conversation will come to an end, in fact, I only wanted to tell you about Harry."
After saying that, he turned around and walked out of the room.
He thought Professor Snape should take some time to think about it.
He just walked out the door and saw Vinda come from the side.
"Lucas, how did the conversation go?"
"There is a high probability of success, what can you do for me?"
Vinda chuckled lightly and said, "We have some results from the investigation."
"Remus John Lupin was recently spotted at a Yorkshire fair, accompanied by a huge black dog."
Lucas raised his eyebrows, showing a hint of joy.
"WOW~ Sirius Black, this white sheep of the Black family finally appeared, just let people keep a close eye on them, the two of them are not easy to deal with."
Vinda nodded, and was about to talk about the situation of the Diagon Alley shop, but she saw Professor Snape striding out of the room.
"I promise you, just tell me what's going on."
"Okay, Aunt Vinda, please be our witness."
Lucas held out his right hand to Professor Snape's.
Both sides will keep what they say and see today confidential.
The moment the unbreakable vow was completed, the space beside Lucas was torn apart.
"Professor, please follow me!"
Seeing the shock in Professor Snape's eyes Lucas felt a little smug in his heart.
Holding each other's hand across the void chasm, the two appeared in Rowena Ravenclaw's library.
"Where is this?"
Snape looked around, he had never seen such a magnificent library.
A dazzling array of books are placed everywhere, and he even saw many ancient books that can only be found in the restricted section of Hogwarts, even some that can't even be found there.
"Welcome to the library of Rowena Ravenclaw."
"Ravenclaw?" Snape was still puzzled.
Until Lucas showed him the books written personally by Rowena.
Professor Snape, who closed the book, had complicated eyes.
After a while, he sighed.
"Hogwarts has existed for thousands of years. Everyone only knows that Slytherin left the Chamber of Secrets, but never thought about whether other Founders did the same as him."
"So you found the book that records the curse of blood sacrifice here?"
Seeing Lucas nod, Professor Snape looked around the magnificent library in front of him again, and soon, he was attracted by a showcase.
"This is..."
He walked quickly to the showcase and slowly named the items in it.
"Ravenclaw's diadem, Hufflepuff's cup, and Gryffindor's sword, it looks like you're only short of Slytherin's locket to collect the relics of the Founders."
Lucas nodded, but did not tell him that he already knew the whereabouts of the locket, and just a few days later, he will be able to get the locket back.
By then the relics of the Founders will be together again. He will also get a chance to draw a diamond lottery.
Seeing Professor Snape staring at the display case so fascinated, Lucas coughed to wake him up.
"Professor, let's talk about business first."
He invited the Professor out of the library and the sunny flower garden outside shocked Snape again.
"How can there be sun here?"
"I was amazed too, please sit down, Professor."
The two sat down on stools in the middle of the flower garden.
Lucas took a letter out of his pocket.
"Back to the original question, where do you think Lily Evans, a Muggle-born witch, learned the Curse of Blood Sacrifice?"
Professor Snape, who had been firm just now, suddenly became hesitant.
Seeing this, Lucas continued: "Professor Snape, I already know the prophecy about [The Chosen One] from Headmaster Dumbledore."
"But I'm curious about how Voldemort knew the content of the prophecy."
Snape froze and it took a long time to relax again.
He said regretfully: "It was me, I overheard the conversation between Dumbledore and Professor Trelawney, and learned the content of the prophecy, which I later passed to the Dark Lord."
"But Voldemort didn't know the complete prophecy, because when I heard just half of it, I was chased away by the owner of the Hog's Head."
Professor Snape opened up about how he had tipped off Voldemort about prophecy afterwards, and how he begged Dumbledore to protect Lily's family after learning she would be a target.
Although he already knew what happened, Lucas still feigned shock.
"I remember the owner of the Hog's Head is called Aberforth Dumbledore?"
Seeing Professor Snape nodding, Lucas took a deep breath.
The next words are very critical, which is related to whether he can successfully plan against the opponent.
"Professor, that means you, a 19-year-old youth who just graduated, went to follow the greatest wizard of this century."
"And successfully eavesdropped on the prophecy without being noticed, no, heard exactly half of the prophecy, and then was kicked out by Headmaster Dumbledore's brother?"
"Do you think it's possible? Do you think that if Draco was stalking you, you wouldn't know about it?"
Professor Snape shook his head thoughtfully.
Although Lucas comparing himself to Draco, that stupid kid, was a bit inappropriate.
But at the time he was following the much older and skilled Dumbledore. It is indeed no different from Draco following himself.
The professor fell silent and Lucas continued: "When Voldemort learned of the prophecy, he followed the prophecy and took the initiative to find the Potters."
"But as far as I know, the child born at the end of July could also have been Neville Longbottom."
Professor Snape nodded: "That's right, but the Dark Lord chose Lily's child."
Speaking of which, Snape's eyes became sad again.
Looking at the man in front of him showing such emotions, Lucas sighed.
He waited until the other person calmed down before speaking again: "The blame lies here. Harry's mother Lily used ancient black magic and sacrificed herself to protect Harry."
"At the same time, Neville Longbottom's parents were also tortured into losing their minds by Death Eaters. Don't you think it's too much of a coincidence?"
Professor Snape suddenly raised his head to look at the boy sitting opposite him.
"It can't be, it can't be Dumbledore."
"Then explain to me why there is such a coincidence?"
Seeing Professor Snape speechless, Lucas continued his efforts: "You said you asked Dumbledore to protect the Potters."
"Then, as the greatest wizard in this world, the one that Voldemort fears, why doesn't Dumbledore become the Potter family's secret keeper himself?"
"If he became the secret-keeper of the Fidelius Charm, who could obtain the location of the Potters from him?"
Snape's expression became a little flustered.
Lucas took another deep breath: "Professor, if I'm right, Dumbledore will tell you afterwards that Voldemort is still alive and will definitely come back to kill Harry in the future."
The benefits of foreknowledge are manifested at this moment.
Hearing Lucas say these words in a firm tone Snape's heart began to waver.
Just at this time, a letter was pushed in front of Snape.
"If anyone in this world knows Dumbledore best, I am afraid that only my father is that person. Take a look, Professor."
Snape took out the letter and started going through the beautiful cursive characters on it word by word.
At the same time, Lucas' voice also sounded from the side.
"Albus Dumbledore, although his mother was a Muggleborn witch, the Dumbledore family has a very long history."
"It is said that when a member of the Dumbledore family is in great need, a phoenix will appear to their aid."
"It all stems from the contract that their family signed with the Phoenix Clan in ancient times."
"My father, Gellert Grindelwald, was bound by a blood pact with Dumbledore, and the two were closer than brothers."
"My father, who likes to study the dark arts, once heard Dumbledore mention that his family has a very powerful black magic."
"This black magic is related to blood. Once it is successfully cast, the designated person will never be able to harm the person protected by it."
"It does sound very similar to the Curse of Blood Sacrifice, don't you think, Professor?"
Looking at Professor Snape's slightly trembling hands, Lucas got up and slowly came behind him: "Professor, let's cooperate, I have a way to help you rescue Lily's son!"
Professor Snape stood up suddenly, and staring at Lucas with a serious face, he asked, "Do you really have a way?".
