When Klein saw "Mr. g" in green overalls appear at Hogwarts castle, he didn''t return to his mind for a long time.

    What''s going on?

    Why did his unlucky uncle show up at school!

    wait.......

    Does that mean Dumbledore already knows about it?

    Countless thoughts flashed through his mind, and Klein''s expression was a little dull.

    But Garrett was in a good mood and said hello with a smile.

    "Hi, little Klein, good morning!"

    "Uh... Good morning."

    Kleinwood nodded.

    "The weather is really nice."

    Like the most ordinary daily greetings, gattler is kind like the grandfather next door.

    "Yes..."

    Klein''s expression was still stiff.

    "So, what are you going to do today?"

    "Wait a minute!"

    Without answering the other party''s question, Klein asked.

    "Mr. g, why are you here!"

    "Oh, this is where I work."

    Gattler showed an untidy row of teeth.

    "I''m already a cleaner officially hired by Hogwarts."

    cleaner?

    Klein looked puzzled.

    What kind of cleaner is a good former terrorist leader and current fugitive!

    "Well, I''ll keep working. Bye."

    Seeing Klein in the morning made gattler in a good mood. He picked up the bucket and staggered away, leaving Klein alone in a daze.

    "This..."

    Klein thought for a moment, but decided to ask Dumbledore later.

    He''s going to class now

    Of course, as a professor.

    The classroom assigned to Klein is on the third floor of the castle.

    He hurried into the classroom with a suitcase.

    As soon as I entered the door, I heard a voice of greeting.

    "Good morning, Professor Greenwald."

    The neat voice was obviously rehearsed in advance. Klein was stunned and showed a brilliant smile.

    "Good morning, students."

    Deliberately accentuated the word "students", he swept the whole classroom and said to himself.

    "Everyone knows me. A year ago, I sat down like you. Unexpectedly, now I have to stand on this platform to give you a lecture."

    After a second, he opened the special suitcase.

    "Although, it''s about how to cook..."

    "Magical animals and magical ingredients cooking" is the specific name of Klein''s elective course.

    As for "defense against the dark arts", the class can only start next semester.

    To get back to business, Klein''s talent in this field has been fully affirmed since he roasted the demon king squid and let wizards see the "new world". He has not only become an honorary member of the "Wizard Food Association", but also qualified to teach.

    This is his first class and a test of his teaching ability.

    "In the first class, we are not in a hurry to operate. First, let''s know the kinds of edible magical animals and plants."

    What you can eat and what you can''t eat is crucial.

    Klein snapped his fingers, opened the suitcase automatically, flew out many handouts and distributed them to the little wizards below - he didn''t want anyone to "commit suicide" in the future.

    "Ah?"

    Originally, he came with a relaxed attitude. Unexpectedly, he still had to read. Those little wizards couldn''t help crying.

    But Klein was as if he hadn''t seen it, and his mouth was full of words.

    "Let''s first learn the part of magical plants. This knowledge overlaps with herbal medicine. Generally, plants that can be used as medicine may not be edible, but edible plants must be used as medicine. This is the knowledge point. You should remember."

    "No fun! We want to eat!"

    "Klein, say something else!"

    "Eat! Eat! Eat!"

    Joking, "magical animals and magical ingredients cooking" is just for fun!

    If you still have to listen obediently, what''s the difference between "astrology" and "divination"?

    Klein was stunned.

    Unkind kid!

    These valuable knowledge, but he summed up the experience of his two lives. He couldn''t find it in books. He was even despised.

    But on second thought, if you can''t show your hand in the first class, it''s really unreasonable.

    Blinking, Klein had an idea in his heart, took out his magic wand and changed the virtual shadow of the fire dragon in the air.

    "Since you let me talk about something else, I''ll talk about something else... The dragon, or the dragon of West, is a well-known dangerous creature, but in our class, its only significance is to prove the richness of the taste of magical creatures.

    Loong?

    Edible?

    Why are these two words so incompatible!

    The little wizards were stunned.

    Taking advantage of this vacancy, Klein had taken out a large piece of flesh and blood that exuded a strong sour smell and looked very hard from his bag.

    "This is dragon meat. I bought this meat at a high price. It''s the tenderloin of Norwegian backbone dragon."

    Klein decided to teach these young wizards a lesson.

    He wants to make it clear: don''t always be lazy and be a salted fish. When you learn magic to a certain extent, it will be more fun.

    Klein wants to cook dragon meat in public?

    The little wizards looked shocked and finally came to spirit.

    "I have five ways to deal with dragon meat. Today''s time is limited. I will only demonstrate one of them. You can have a good look and learn."

    "Protection and camouflage of soul (※)" "contract law of Yin-Yang God", "curse and anti curse", "how to drive the devil without cost", "shell maintenance of Egyptian Scarab", "conjecture about the combination of corpse ghost and skeleton demon"

    There are many interesting topics in Klein''s black book, "five attempts at dragon meat cooking" is one of them.

    Generally speaking, people don''t try the taste of dragon meat

    But he is not an ordinary person.

    "First, wear protective gloves and clean the dragon meat with clean water. Remember, we must do a good job in protection, because the dragon blood is highly corrosive, and it is very dangerous not to wear protection.

    After washing, marinate for ten minutes with the secret sauce made of coarse salt and Osmanthus fragrans. Oh, by the way, the reason for using Osmanthus fragrans is that there is a strong acid dissolving factor in Osmanthus fragrans, which will neutralize with dragon meat... "

    Klein talked about the cooking steps, but then he turned to some other places.

    Those little wizards are stupid.

    Huh?

    Isn''t this a cooking class?

    Why are there magical biological habits, herbal growing environment, magic medicine formula and some knowledge that you can''t understand?

    incorrect!

    This painting style is obviously wrong!

    "Well, that''s almost the part of the sauce. Have you learned it?"

    After preliminary treatment of the dragon meat, Klein raised his head and looked at the stunned students.

    learn?

    It''s impossible to learn without learning. Okay!

    It''s true that learning is useless
