But...... The first to get started is the level 8 Divine Blade, which is unexpected by Louis.

He only knew that he was very talented in black magic, but he didn't expect it to be so outrageously strong, and he couldn't help but have a ruthless thought in his heart.

Do you want...... Learn the Unforgivable Mantra?

This idea was quickly dispelled.

……

As soon as the two men who had finished practicing the spell stepped out of the door of the Room of Requirement, they saw Dumbledore standing in the doorway with his sleeves folded, as if waiting for the two of them.

"Professor." The two of them greeted each other in unison.

"It's good to be young." Dumbledore looked at him with a leisurely sigh, "But it seems a little too early to be in love at your age. ”

Catherine's face turned red, and her eyes wandered to the side. Louis didn't think anything of it, and he asked directly, "So...... Professor: You don't sleep at this time, if you don't wake up, then ...... Must have been awakened. ”

Good guy, what if you put this and you put it here?

Dumbledore choked, coughed twice, and said, "It's rare to see hard-working young people like you two, and it would be nice if your classmates were like you two." ”

"Looking at your appearance, you should not just come to the two of us to feel about life, there must be something." Luis tries to cut the old Deng in the middle lane.

Dumbledore reached out and pulled a piece of lemon sorbet out of Louis's pocket, peeled off the icing unhurriedly, and put the candy in his mouth. Feeling the sweet aroma of lemon, he couldn't help but squint his eyes, and after a while, he slowly said, "There is something that Luis needs you to help me, the incompetent principal, think of a way." ”

Louis:?

"Well, I've always wanted my classmates to be enthusiastic about their studies, but the effect is not obvious, so I would like to ask you, who have studied in the Muggle world, if there is any good way?" Dumbledore blinked, "I understand the principle that studying should be properly combined with work and rest, but our classmates seem to be too relaxed. ”

"You said it earlier, I thought something was going on." Louis smiled: "I have a lot of ways here." ”

In the previous life, there were a lot of rolls, and it was obvious that he had become a good doctor for a long time.

"Then it's settled." Dumbledore's face was back with a playful smile.

"I hope you don't regret it." Louis said quietly.

Dumbledore looked up and thought about it, but was interrupted by a sound of footsteps: "Hmm, it seems that Mr. Filch is here, I think you two may have some trouble, good night~"

With that, Dumbledore slipped away very unjustly.

Louis patted the shoulder of the senior sister who was still blushing and reminded, "Don't blame me for not reminding you, Filch is coming up......"

……

Louis decided to give the unrighteous old Deng a big eye.

Harry was still honest and obedient, he had taken Louis's instructions to heart, and had been preparing for the Potions lesson last night. At breakfast, Louis also checked his homework preparation, and the effect was really good.

Draco didn't know what was wrong today, his little face twisted, and he didn't know who he was awkward with.

After eating, it was time for Potions class, a full hour of class, and everyone had been sitting in the gloomy classroom for a long time, and Snape was late.

He walked with the wind, and his black cloak was lifted by the movement of his walking, like a black bat staggering on the ground. Standing next to the podium, he scanned the classroom twice, picked up the roster and began roll call.

When it came to Harry, he stopped.

He whispered in a slow tone, "Oh yes—Harry Potter, it's our new ...... What a famous person. ”

Harry looked at Snape without humility or arrogance, thinking to himself what Louis had told him.

"Professor Snape hates people looking around, so you'd better keep your eyes open and look at him seriously."

His eyes were as dark as his hair, cold and hollow, Harry thought.

"This course doesn't require you to wave your wand stupidly, you're here to learn the exact science and rigors of potion configuration." His voice was not loud, as if it was pronounced in a nasal voice, and he spoke slowly: "I don't expect you to really grasp the beauty of the white smoke and fragrance of the simmering cauldron, you won't really understand the magic of the liquid that flows into people's veins, the magic of the heart-stirring and will-shifting...... I can teach you how to increase your prestige, brew glory, and even prevent death—"

At this point, he changed his tone: "But there must be one thing, and that is that you are not the kind of stupid fools I often meet." ”

After the classic opening remarks, the class fell silent, and Louis glanced to the left at Harry, and when he saw that Harry was also secretly looking at him, he gave him a cheering look without a trace.

"Potter!" Snape suddenly called a roll call, and Louis looked at Harry with a startle: "What will I get if I add daffodil root powder to wormwood infusion?" ”

"A powerful sleeping pill, Professor, is a water of life and death."

Snape tugged at the corners of his mouth and walked over to Harry, staring at him with an unblinking eye and a slight smile on his face, but quickly retracted it - for he saw Harry's face and his expression immediately turned to disgust.

A good pair of eyes, why do you have a face?

Harry didn't see Snape's micro-expression, just stared at his dark eyes.

"So, Potter...... If I asked you to find me a piece of bezoar, where would you find it? ”

"In the stomach of a cow, Professor." Harry replied quickly, it was all the focus of Louis's drawing for him, and it was a piece of cake.

Secretly grateful to Louis, he wondered why he had to ask his good friend to eat two chocolate frogs or something.

“well，well…… Potter, what is the difference between scaphoid aconitum and lupus aconitum venom? ”

Snape raised an eyebrow, and no one could tell anything from his expressionless face.

"Wolf venom Aconitum and Scaphoid Aconitum are the same plant, also collectively referred to as Aconitum aconitum, Professor."

Harry's self-confidence had also risen, and Louis had tested him on all of these questions today, with a relaxed and confident smile on his face and emerald green eyes blinking at Snape.

Snape was stunned, he remembered the same pair of eyes, the owner of those eyes was so relaxed and confident in Potions class, and he always looked at him with a slight smile.

It was his lost youth.

"It seems...... Fame is sometimes not without reason. Snape pulled out an ugly smile: "Gryffindor plus five points." ”

At this moment, the Gryffindor cubs cheered as if they had blown up their nests, and Harry's smile as he looked at Snape was sincere. Slytherin, on the other hand, looked incredulous, and Draco even whispered to Louis about whether Professor Snape was someone else pretending.

"Silence!" Snape's face was expressionless: "Disrupt the order of the class, Gryffindor deducts five points!" ”

Harry's smile choked back.

"It doesn't seem so." Draco's eyebrows furrowed again, and he was happy to see Gryffindor unlucky.

After all, the Snake Courtyard and the Lion Courtyard are inherently incompatible, and Louis belongs to the alternative among the other.

After interrogating Potter, Snape recounted how to make the scabies potion twice, and then divided his classmates into pairs for them to experiment. Harry's group was unfortunate enough to sit next to Neville and Seamus - the two were Crouching Dragons and Phoenixes, one ruthless who could boil the cauldron and the other a Demolitionist.

But Harry didn't know, just smiled heartlessly. In fact, even if he knew, according to his kind character, he would not dislike them.

Louis and Crabbe were separated, and seeing that he didn't look like he could make potions, Louis chose to let him do some rough work, such as grinding poison tooth powder.

Snape dragged his long robe around, spitting venom uncontrollably. Louis, who had the half-blood prince's notes in hand, was not afraid at all, and he cooked a perfect pot of scabies potion with ease.

Looking at the blue potion in Louis's cauldron, Snape nodded with satisfaction: "Very good potion, Slytherin - plus five points." ”

Before he could finish speaking, he heard Potter shout loudly, "Neville! No! Don't add porcupine thorns! ”

The whole classroom looked at Harry, and after he quickly snatched the porcupine thorn from Neville's hand, his face showed a look of the rest of his life: "Neville, before adding the porcupine thorn, you must remove the pot from the fire, otherwise the potion will corrode the pot!" ”

The process of making the scabies potion had already been carefully studied by Louis at dinner this morning.

"Potter is right." Snape's mournful voice rang out behind Neville, "Longbottom, it seems like you should cram your troll-like brain into a little more, if not a little ......"

"As for you, Yi ...... Miss (English custom is Miss first, last name or first name) ...... Mr. Potter. Snape looked at Harry, a flash of thought in his eyes: "Being able to alert his classmates in time to avoid the possibility of him entering the medical wing - Gryffindor plus three points." ”

Harry's mother, whose last name was Evans before marrying James.
