Compared with the purposeful Harry and Hermione.


    Ron Weasley just walked up to the podium simply because they didn''t leave.


    The Weasley family, the little son who lacks self-confidence, doesn''t even dare to look directly into Cole''s eyes.


    "Professor."


    Harry hesitated and looked at Hermione.


    The girl took a deep breath, held the class notes in her arms, calmed her excited and slightly frightened heart, and said, "Professor walker, I don''t know... Can we take up some of your valuable time?"


    After the first lecture and previous humble abode experience.


    At the moment, Cole is as terrible as Professor Severus Snape in the eyes of Hermione Granger or other students.


    Compared with the gloomy and severe of the latter.


    Across the street.


    They can smell the eternal smell of blood and violence on the black magic defense assistant.


    It seems that if you don''t agree, you''ll shoot them in the head.


    however.


    Harry''s attitude showed great trust and admiration, organized the language and said, "Professor, about the power of will.


    After Cedric died, I fought the mystery man.


    At that time... "


    That''s it.


    He glanced at his two best friends.


    Hermione naturally understood what he was worried about and comforted, "don''t look at me like that, Harry. No one doubts you here.


    Right, Ron. "


    Ron, whose thoughts broke down, was stunned. Under the girl''s eyes, he quickly smiled, "er... Of course! I''ve always supported you, brother.


    God knows whether it''s true or false. "


    Don''t wait for Harry to go on.


    Cole leaned against the podium and frowned. "At that time, you should have seen your mother, or someone else who might have died, right?"


    Hear him.


    Harry''s expression was once very shocked. He spread his hand, his voice was excited and incoherent, "Cedric... I saw Cedric and my parents.


    They... They... "


    Cole raised his hand to signal that he didn''t have to go on.


    Hermione and Ron looked at each other.


    Even wizards.


    It''s hard to believe that the living can see the resurrected dead, or the soul.


    Signal Hermione to close the classroom door.


    After a silence.


    Cole explained, "the research topic related to soul has always been an absolute taboo in the magical world, but I can tell you exactly, Harry.


    What you see is not what you think Cedric or your parents are.


    They exist in a form very similar to the spirit of resentment.


    They only have part of their memories in their lifetime, rely on extremely strong obsessions, and exist in another dimension, but because they are well intentioned obsessions, they do not become evil spirits.


    It may be difficult for you to understand this description, but Dementors are many evil spirits, imprisoned by a very powerful evil force beyond human control.


    They hate the living and are full of greedy desires for the good memory and soul of mankind. "


    Hear this.


    Hermione quickly wrote down what she thought was the key part in her class notes, raised her hair and asked, "what does it have to do with the power of will?"


    Cole turned and picked up a piece of chalk.


    Draw a big circle on the blackboard and write "Muggle world and magic world", and draw a small circle inside and write "soul."


    Then turn the chalk horizontally and fill the whole blackboard.


    Draw a question mark in the upper right corner, write ''unknown'', and write ''ether'' in the lower left corner.


    Finally, press your hand on the chalked blackboard, leaving a handprint that coincides with the small circle.


    At Hogwarts, even into the Ministry of magic in the future.


    All wizards have little access to soul related research.


    Just like Muggle world, human cloning is regarded as a taboo research against ethics.


    Hermione took her pen and class notes with a serious expression and concentration.


    Even the absent-minded Ron began to have doubts about what Cole drew on the blackboard and his appeal for the answer.


    Cole patted the chalk ash on his right hand and explained, "the real world is everything around us that we can perceive now.


    Air, stone, fire, water... Etc.


    These places that I have smeared are borrowed from an assumption mentioned in human scientific research, that is, the ubiquitous medium ''ether'' in the universe overlaps with the real world... Or exists in another dimension.


    We live in such a world.


    This little circle.


    It represents everyone''s soul, the exact existence between the real world and the etheric world, and our will.


    All necessaries for witches to cast spells... "


    That''s it.


    The smartest Hermione had understood what Cole wanted to express, and spoke quickly. She then said, "just like the fingerprints we just pressed, we can turn what we can''t perceive into concrete things that we can perceive or even see."


    "Correct answer, Miss Granger, a powerful wizard, must be idealistic.


    Do you know why the killing spell used by black wizards is far more lethal than ordinary Wizards? "


    It seems that the past classroom atmosphere has been found again.


    Holding the class notes, the girl smiled and replied, "because they are keen to destroy and kill others."


    Get the exact answer.


    Hermione''s expression was very satisfied.


    Ron looked confused and confused.


    But Harry was silent and became more and more worried.


    obviously.


    About Voldemort''s far more powerful strength than others, he already had the answer in his heart.


    That is unparalleled, ordinary people can never understand, vicious and extreme evil will.


    Before leaving, let Hermione clean the blackboard and warn them not to tell untrustworthy people what they are talking about today.


    To avoid young people with black wizard potential.


    Out of curiosity about the soul, he embarked on the path of evil.


    But in the second half, Cole didn''t tell them.


    Just as Tom Riddle asked Horace Slughorn many years ago.


    The next week.


    In every defense against the dark arts class, Umbridge teaches under Cole''s supervision.


    After a week of "torture" by the old pink witch, the students who had feared and complained about a teaching assistant finally began to miss the first black magic defense class with Cole''s participation.


    Compared with the boring study now.


    To some extent.


    The actual teaching, which was originally particularly frightening in the eyes of students and almost became a psychological shadow, inexplicably became exciting, thrilling and exciting.


    Although encouraged by other students and Hermione, Harry asked cole to give them another practical class.


    But was denied by the other party.


    The reason is also very violent and bloody: I''m not a wizard and can''t teach you anything about casting spells. Go on. Maybe I''ll consider catching one or two black wizards and dealing with them in court.


    In order to teach you the practical skills to deal with the black wizard.


    If for other reasons.


    Maybe students will think Cole is deliberately prevaricating.


    As a result, after Harry told others the reason why Professor Walker refused, including Hermione, who was always eager for knowledge, everyone''s attitude was surprisingly consistent.


    The current classroom atmosphere... Is very good.
