With the anticipation of the classmates, a familiar figure of Alan walked in, it was Albert.

Dumbledore placed many protective personnel around Harry Potter, such as Harry's neighbor, Mrs. Fig, who was a squib and did not have the ability to cast spells, but somehow gained the trust of Harry's obnoxious aunt Penny.

When there was something going on at home, such as when the family of three needed to go on a trip, Aunt Petunia would occasionally put Harry in the care of Mrs. Feige if it was too long.

It seems that Albert belonged to the Ministry of Magic sent by Harry to be the security guard at the school, but a pure-blood wizard actually came to teach science, can he be competent?

"Hello students, I'm your new teacher, Albert Harris. ”

Albert, disguised as a teacher, wrote his name on the blackboard in style.

"Maybe you think that science has nothing to do with your daily life, that it is a particularly serious, boring, dispensable subject, and I want to tell you, wrong!"

Albert waved the whip in his left hand, and an empty cup appeared in his right hand. In front of everyone's eyes, the cup was filled with pure water out of thin air.

Albert flicked his hand, and another glass of pure water appeared on the right side of his hand as if it had been copied.

"Alright, now it's two glasses of purified water. Do you see clearly?" the students were stunned and nodded.

"Now, I want to turn one of those glasses of pure water into a thing. Which glass do you want to change?"

Albert winked mischievously, and his classmates screamed and pointed at the two glasses of water.

Albert made a pattern with both hands, and the pure, clear-looking water on the right turned into a yellow liquid at a rate visible to the naked eye. The cheers were endless.

"It's so cool that the new teacher can do magic, what's in that cup?"

"It's a drink, right?"

"No, I think it's oil!"

The students who were mobilized were gossiping, guessing the intentions of the new teacher.

"Shh......h And that's just the beginning. Albert's right hand swayed, and a card appeared in his hand. The students under the podium all widened their glasses, for fear of missing the wonderful moment.

Then Albert picked up the credit card, covered the water glass, buckled it upside down on top of the oil, and slowly moved the card out of a small slit, and a miracle happened.

The fine foam rises and falls, the oil below rises little by little, and the water settles little by little, until the water above completely turns into oil, and the oil below becomes water.

"Teacher Albert is so handsome!

"It's amazing, I don't know how it works!"

"I really want to learn. ”

Cheers and chatters came and went. Even the students in the next class couldn't help but come out to take a look.

"Okay, please be quiet. Now, who can tell me, apart from my magic tricks, what the principle is? If you've studied a science textbook and know it, it's not a problem. ”

Teacher Albert pressed down with both hands, and the students were completely subdued by his magical means, and instantly fell silent.

How noisy the classroom was just now, how quiet it is now.

Everyone thought it was amazing, but at this time they all lowered their heads to avoid eye contact with the teacher.

"Does no one know?" said Mr. Albert, who seemed a little disappointed.

"What kind of magic trick, the initial method is clearly silent spelling, Albert even ignored the law prohibiting casting spells in front of Muggles, just because he is a member of the Ministry of Magic?" Alan muttered to himself.

"After all, it's my brother, and he's on his first day of class, so let's help him round the field. Thinking of this, Alan raised his hand. In order to break the silence in front of him, Albert immediately motioned for Alan to get up and answer.

"Water and oil should have been prepared by the teacher, and the water and oil exchange should be because the density of water is greater than that of oil, so it will sink through small cracks. The oil is squeezed and goes to the cup above. ”

As soon as the words fell, the classroom burst into thunderous applause.

Flegg and Harry, who were at the same table, looked at Alan with admiration and slapped desperately.

"I couldn't be more perfect than you say. What are you waiting for, let's take a note here, this is our main point today. Albert clapped his hands, and the classroom was filled with the rustle of pens sliding on paper.

After class, some little girls followed Albert out of the classroom, and one of the boys couldn't help but show off the new science teacher's experiments and magic tricks just now, and his tablemate looked at him with a look of intellectual retardation: "You idiot, I'm also in this classroom, taking his class." ”

"Alan, the new teacher's surname is Harris. Harry couldn't help but say to Alan after class.

Alan nodded, and couldn't help but think of his name again, "Well, he's actually my brother, speaking of which, when my father named us when he first named us, I don't know why he didn't turn a few more pages to name Daquan, except for my sister Daisy, second brother, my eldest brother, myself and my sister, all of which were names that he found starting with A from the first few pages...... My mom complained about him for a long time. ”

"Don't sit still, let's go out and play," Flegg warmly invited, and he had been thinking about it since before the lesson.

On the playground, the three people who were playing basketball were surrounded by several big guys. "Look, what do I see! With that, they snatched the basketball from Flleg's hand.

It's really ghostly, and it's Dudley and a few of them.

"Dudley, I'm not afraid of you!" Flegg yelled at Dudley in annoyance as he saw the basketball being snatched away.

"Haha, Harry was my first punching bag, and now the second and third sandbags are delivered to the door!" Dudley squeezed his little malicious eyes and punched his fists excitedly.

For the first time in his life, Alan was bullied as a student, but his previous status as a teacher made him feel a little unreal and stopped thinking about reprimanding them.

However, Alan currently has no way to rely on spellcasting to protect himself without a wand, except for using the cleansing charm and the disillusionment charm that comes with the equipment, and it is illegal to expose magic in front of Muggles.

"Surprise Mission: As long as you don't get caught by Dudley and a few people, you can get the "Elementary Alchemy" that helps wizards improve their physique and increase their body muscle control as a reward. Please do your best!"

Obviously, Harry, who is used to bullying, is better at dealing with this kind of situation, Harry and Flegg glanced at each other, and pulled Alan who was stunned by the sudden task of the system. "Run!" Harry yelled.

Escaping was a common occurrence for Harry, and the skinny Flegg scurried left and right, slippering without sparing his hands, while Alan, who had just received the task, had sufficient nutrition and growth, and had a relatively strong physique, suddenly stood still in the process of escaping, punched the bridge of the nose of the nearest pursuer behind him, knocked him to the ground, and ran directly to the teacher's office.

Dudley and the others screamed in annoyance as their downed companions ran amok behind them, causing numerous complaints wherever they passed.

"If I'm not mistaken, are you guys fighting?"

"Albert's voice, I'm safe. Alan panted and hid behind Albert.

Moken's laughter froze on his face before he could stop. Dudley four, you push me, I hit you, don't dare to run away, let alone step forward.

"Teacher Albert, as you can see, Dudley and they are bullying me, Harry, and Flegg to turn us into their punching bags. We didn't want to be beaten, so we had to run around. ”

Alan articulates a clear picture of the cause and effect.

"My brother and his protector were bullied by a few Muggle kids right under their noses. Albert suppressed the anger in his heart and asked in a deep voice, "Is this what Alan said?"

Harry and Flegg nodded desperately, as if that would prove the reliability of Alan's words.

Dudley's four-man period Ai Ai, nothing can explain it.

Dudley put his hands behind his back, refusing to let Albert discover his new boxing gloves.

"Your name is Dudley, isn't it, what's on your hands?"

"Nothing. Dudley hid tighter.

Albert pursed his lips and waved the whip with his left hand behind his back, and Dudley staggered a few steps as if he had been pushed hard, supporting the wall with his hand to avoid falling.

"Who's pushing me?" Dudley yelled, and Moken and Peel behind him looked at him like hell, and in their eyes, Dudley took a few steps forward as if he were drunk.

"It turned out to be a boxing glove, it seems that Dudley has his own interests and hobbies, which is good, but your level is not very good, and it is not good to make a punching bag and on your classmates. I'll teach you. ”

Albert didn't ask Dudley's permission at all, grabbed Dudley's fat hands, took off his boxing gloves, and reluctantly stuffed his own hands inside.

"Concentrate, watch!" Albert didn't give Dudley time to react at all, and threw a quick punch.

Dudley was so frightened that he didn't move, because Mr. Albert used him as a reference, and his left fist came out of his left ear, and his right fist was blowing in his right ear, and he could barely see how Albert punched, only a fist in front of him.

It seemed like a long time, but it was actually fast, and as Albert stopped making a move, Dudley gave off and fell to the ground.

"Don't let me see you bullying your classmates in the future, if you want to sue your parents, just sue your parents. ”

Albert took off his gloves, shoved them back into Dudley's arms, patted his palms stained by Dali's sweat in disgust, and turned away.

Amid the laughter of his classmates, Dudley and the four of them left in a gloomy manner, without even saying a cruel word.

"Wow, Alan, your brother is so cool!" Flegg couldn't wait to admir.

"If only I had Mr. Albert's skills, in which case Dudley would use me as a punching bag again, and I would beat me back. Harry looked envious.

"The conditions of the assault mission have been answered, congratulations to the host, and a copy of "Primary Alchemy" will be rewarded, please keep up the good work. ”

P.S. In the spirit of being responsible for the work, the novel was revised again, and chapters 9, 10, and 11 were carefully considered, removing some of the previous immature plots and revising and integrating them into chapters 8 and 12. I hope the revised version will be liked by everyone. Than the heart.
