Klein didn''t tell the truth completely, no doubt, but Snape''s identity was definitely not known by a third person.

    Dumbledore was confident in this.

    So

    There''s only one answer left.

    That pair of blue eyes may indeed have peeped into the future!

    "I must say, I don''t fully believe you, but... I don''t feel any hostility from you."

    There was a moment of silence, and the old man spoke slowly.

    "I''m curious. You can completely hide yourself until graduation. Why do you deliberately reveal that you know black magic?"

    This was the last thing Dumbledore understood. If Klein hadn''t deliberately revealed it, he couldn''t see any clue.

    "For me, magic is magic. There is no good or bad, regardless of black and white."

    Klein straightened his waist and seemed to have a fire in his eyes in the light.

    "Wizards can turn water into wine, drive thunder and control electricity, and even live forever. What do they rely on?"

    What do you rely on?

    Magic!

    Is it necessary to ask such an obvious question?

    The presidents of all ages felt speechless, but Dumbledore behind his desk fell into meditation.

    "Faith!"

    Klein gave the answer with great certainty.

    "Just because we believe that water can be turned into wine, water can be turned into wine. The essence of magic is" believe, there is, don''t believe, there is nothing. "

    There was a sudden silence in the office.

    "Magic affects the heart? That''s just an excuse for cowards'' lack of firmness. Real wizards should control magic, not be controlled by magic."

    Staring into Dumbledore''s eyes, Klein asked with a smile.

    "Professor, did you defeat my uncle Garrett with only the disarm spell Greenwald. "

    "This..."

    The old man was speechless for a moment and didn''t know what to answer.

    As we all know, most powerful magic is black magic. In fact, he did master some taboo spells that could not be easily displayed.

    "You still haven''t answered my question. With your knowledge and experience... Even I dare not say I can beat you. What''s the point of you coming to school?"

    At first Dumbledore only regarded Klein as a gifted teenager, but now he has put them in the same position.

    "I like school. Isn''t eleven the age to go to school? Besides, I still need to learn a lot. I don''t need magic potions, deformation and defense against the dark arts."

    Magic is a profound knowledge. No one can master everything. Klein is a master in the fields of ordinary magic spells, taboo spells, summoning rituals and alchemy, but potions and transfiguration are just at the entry level.

    If you have the opportunity to light up new skills, why not?

    "My intuition tells me that that''s not your real purpose. If you can''t convince me, I''ll regret to tell you, Mr. Klein, that you''re fired."

    Dumbledore could feel that Klein had no hostility, but as the principal, he had to be responsible for the teachers and students of the school.

    A wizard proficient in black magic is too dangerous.

    "Well, because I want to hide myself."

    The old fox was really hard to fool. Klein shrugged and told the truth.

    "I need to use Hogwarts and Professor your prestige to save me a lot of trouble. You know, if I want to be emperor in ten years, I can be emperor as predicted in my dream, but that''s not what I want."

    When Klein finished, Dumbledore''s face remained unchanged.

    "As long as greendevo''s blood is still flowing in my veins, prejudice will always exist. I need your help."

    The young man''s eyes were burning when he met the old man''s examination.

    "Unfortunately, that doesn''t convince me."

    Dumbledore shook his head and his breath suddenly became extremely dangerous. He could not accept the answer.

    "What if I say I can help you completely eliminate Voldemort?"

    Klein was not surprised and offered another condition.

    A condition Dumbledore could not refuse!

    "Oh?"

    Hearing this, the old man frowned unconsciously.

    "After all, I didn''t do anything bad except curse Muggles, which you know very well.

    And I don''t have to say more about what Voldemort did. "

    Klein struck while the iron was hot.

    The old man frowned deeper.

    Seeing this, Klein showed an expression as expected. In fact, he was ready to be questioned by the Ministry of magic at any time, but he waited left and right. No one came to him. Obviously, Dumbledore helped him deal with the head and tail.

    With the old man''s ability, it is easy to find out what he did after he came to England.

    "I''m sorry I let you come to Hogwarts now..."

    Dumbledore breathed deeply, his eyes moving.

    "I thought you''d be glad."

    Klein smiled back and relaxed.

    "Lucky? Oh, yes, it''s more dangerous for a wizard like you to stay outside."

    The old man showed a suddenly enlightened expression and put away the old magic wand that had changed its owner.

    "So, how are you going to help me?"

    "You help me deal with the Ministry of magic and external public opinion. I help you protect the students in the school and deal with Voldemort and his followers."

    Klein was obviously ready and didn''t want to speak.

    "How do I know you won''t break your promise."

    Most users of black magic were insidious and cunning, and Dumbledore had to guard against it.

    "I can make a blood oath."

    Klein still did not hesitate.

    "Blood oath?"

    Dumbledore was stunned, and a person and some past events flashed through his mind. After thinking for a long time, he smiled bitterly and shook his head.

    "No, blood oath is the most reliable thing and the most unreliable thing. I prefer to believe my intuition than magic. Klein, I''m willing to try to believe you. I''m willing to believe you won''t become another" Voldemort ", even if you''ve surpassed him in danger..."

    "Thank you. It''s worth a Christmas present. You''ll be surprised at that time."

    Klein knew that he had persuaded Dumbledore, and his smile became brighter and brighter.

    "I''m looking forward to it."

    Dumbledore, who put down his heart knot, also smiled, and the momentum of terror disappeared without a trace.

    "In that case, please allow me to cast the last spell tonight."

    Holding up the red sandalwood wand, Klein gestured slightly.

    "Please."

    Dumbledore raised his hand, arranged his dark purple robe, and walked to the door without delay.

    "What?"

    The principals finally recovered from their dialogue and looked at each other suspiciously.

    What does "the last spell" mean?

    "A forget is empty."

    When Dumbledore was ready, Klein turned and cast a "forgetting spell" on the portraits. How could the "missing body", which is not even the soul, resist his magic, and his eyes suddenly stagnated.

    "No problem. All the troublesome memories have been eliminated."

    The so-called secret, of course, is that the fewer people know, the better.

    Klein went to the bookshelf and picked up a copy of advanced alchemy.

    "Good evening, Klein."

    They are all old characters of strength school. When Klein stood still, Dumbledore entered the role almost instantly.

    The principals who recovered from the confusion failed to find any flaws.

    Their cooperation is perfect.
