"Xana, what are these?"

Hermione, who was doing her homework in the break room, saw Xana walk in from the outside dragging a large floating bookshelf.

"The Potions reference books I ordered from the Blotted bookstore were very helpful from Percy, and I borrowed some more from the twins. When I entered the school, because I was working on other things, Potions wasn't a very high priority. This mistake is about to be corrected, and I'm going to do my best to build my own potions research system, and that situation must not happen again last time! Be sure to knock Snape to the ground! ”

Look at the burning Xana, Hermione Khan! It's the rhythm of working against the teacher.

"Oh! Our little Xana is on the offensive against Lord Snape! Oh! We've got your back! ”

The Weasley twins were afraid that the world would not be in chaos, and many of the students who had been poisoned by Snape were also making a fuss. Although they didn't have the courage to confront Snape together, they were still willing to make a fuss.

After sending these soy sauce crowds away, Xana began to enter the potion data into the database for analysis. Xana, who had been planted once in Snape's hands, decided to work hard, at least not to be so passive anymore. Xana not only asks for help from her senior classmates (mainly the Weasleys), but also searches the Infinite Library for information on magic potions from the rest of the world in order to "use the stones of other mountains to attack jade".

"It's weird to have an infinite library."

Xana disconnected from this super database that was said to be built on the root of her sister, and looked at the "Alchemy of Azeroth" in front of her very satisfied. The only thing that is unhappy is that I don't know why I can only read the information in the library in one direction, but I can't leave any records, otherwise my sister would probably have found herself a long time ago (in fact, she had already found it), which is Xia Na's biggest resentment against the library.

In the next few days, Hermione watched Xana transform into a potions maniac in her spare time, either reading potions books or herbalists, or asking her seniors about potions, either in the potions practice room or on her way to the potions practice room. In addition to the initial scabies potion, there are also various primary and even intermediate potions such as Courage Potion, Energy Rejuvenation, Simple Healing, and Forgetting Potion.

"Xana, are you alright?"

The roommate's practice of potions day and night made Hermione very worried. Although the level of potions has advanced a lot of learning progress, can this Cheng dù deal with the teacher?

"Rest assured, the sampling of the properties of the basic drugs will be completed, and the improvement of these potions in the future can be completed only by computer simulation, modern scientific and technological analysis of traditional experience, Snape, we will see!"

"Huh?"

Hermione couldn't connect potions to computers at all, and Muggle appliances didn't work at Hogwarts, really?

"By the way, do you want a feather potion? I've refined a lot, and I can give you a discounted price. ”

"Huh?"

Hermione, who was still thinking about the computer just now, couldn't think about it, and the jump was a bit big.

"Percy posted a notice at the door of the lounge just now, didn't you see it when you came in? We start flying lessons with Slydrin students next Thursday. ”

"Oh no, I'm going to borrow a flight book and read it."

Hermione ran to the library in a hurry.

Flying lessons are coming, which makes all the students (most of the boys, to be exact) excited or nervous (most of the girls). Everyone from the wizarding family chattered about Quidditch, and many of the students bragged about their own flights.

But the ridiculous stories of flying over helicopters or nearly crashing into gliders show that people don't actually have much experience flying. Xana, who spent a lot of money some time ago, took the opportunity to start a business with the Weasley twins, selling feather potions that could fall like feathers.

"Happy working together!"

Working with the Weasley twins to sell feather potions in four houses was so successful that many students who were afraid of falling off bought a bottle or two just in case. The good sales results made Xana's wallet bulge a lot, which greatly made up for the consumption of previous potions research.

However, Xana later discovered that sometimes even buying a feather potion was useless, as Neville showed when he was holding his hands and crying.

"I didn't expect Neville to forget that he didn't bring any potion in the morning."

This morning, Neville's grandmother brought him a memory ball, which turned red as soon as he got his hands. It's a pity that although this thing can turn red and remind you when you forget something, it can't tell you what you have forgotten. Coupled with Malfoy's passing trouble, everyone forgot about it, and Neville lost it every day anyway.

As a result, everyone had just started to practice riding a broomstick, and Mrs. Hodge had just corrected everyone's posture for everyone to try to float a little, and Neville flew into the sky.

"Come back, kid!"

Mrs. Hooch shouted, but Neville went straight up, flying like a cork coming out of a bottle.

"Drink the feather potion and jump down!"

"Oh no! I forgot the potion in the dorm! ”

Xana sighed helplessly, knowing that Neville had forgotten something in the morning. No matter how good the protection measures are, if you forget to use them, they are useless.

Panicking, Neville quickly slipped off the side of the broomstick, and then—thud down into the grass and shrunk into a ball. His broomstick was still rising higher and higher, and then began to float slowly in the direction of the Forbidden Forest, disappearing.

Mrs. Hodge had to take Neville to the infirmary, and although she warned everyone not to use a broom or she would be kicked out of the school, but when you think about it, you know that without the teacher's suppression, two groups of people who don't like each other at all will be honestly weird.

In order to fight for Neville's lost orb, Slydrin and Gryffindor's daily routine (mouth cannon or live PK) begins, with Harry and Malfoy arguing from the ground into the air, and then ending with Harry swooping at high speed to catch Malfoy's orb and being taken away by Professor McGonagall.

"Harry is going to be fine, is he?"

Hermione was worried about what would happen if she was kicked out of school as Mrs. Hooch had said.

"Rest assured, the school is not going to expel a student for this. At most, he will deduct points and labor penalties or copy school rules or something. ”

Xana reassured.

Sure enough, during dinner, Xana and Hermione saw Harry eating happily at the dinner table, he and Ron were eating and chatting together, and it seemed that they were not punished at all, and then looked at Gryffindor's gem bar, it should be fine.

But as soon as she had given a sigh of relief to Gryffindor's gem, Hermione heard another thing that drove her crazy - a wizarding duel, where Malfoy and Harry met at midnight in the prize showroom.

"Sorry for the excuse."

"Can you let people stop eating here?"

Ron was impatient.

"I couldn't help but eavesdrop on what you and Malfoy said—"

You must not wander around the school at night, think about how many points you will lose to Gryffindor if you get caught, and you will definitely get caught. You're so selfish. ”

Hermione's preaching began, but this kind of preaching didn't mean anything to the bear children in the early second year of secondary school except for disgust.

"It's really none of your business."

"Goodbye."

Only the back of Hermione's head was left.

Late at night, Xana waited for Hermione to come back while reading a book in bed, Hermione had gone down early to block Harry and them, but the wait was unexpectedly long, and it took an unknown amount of time to see Hermione come back angrily.

"They went so late? How many died in the duel? ”

"There is no duel! But we almost got bitten to death. ”

"Bitten?"

Hermione changed out of her dirty dressing gown as she recounted the terrifying adventure she had just had. Pigeons were released by Malfoy; chased by Filch; In the end, he encountered a three-headed dog guarding something and was almost bitten to death.

"This Night's ......"

Xana shook her head, turn off the lights and go to bed.

Since that day, Hermione and Harry have started a cold war, although the relationship was not much better before, but now Hermione sees the two of them as a pair of troubles.

Xana didn't care about any of this, the most important thing now was to get the field back from Snape, and the moment was coming soon.

"Today we are learning the configuration of the Kling Potion, who told me what the effect of the Kling Potion?"

As usual, Hermione's hand was raised high, but Snape ignored it as usual, and nodded to a triumphant Malfoy in reply.

"It's an effective cleaning disinfectant, and we use the Kling potion to quickly clean all kinds of stubborn dirt, sir."

"Cut, who still makes this thing by themselves now, isn't it good to buy ready-made directly."

Tired of Malfoy's appearance, Ron muttered underneath.

"Gryffindor deducts 1 point, Weasley. If you're only going to buy Galleons with you for your final exams, I think you'll be in for a surprise. ”

No one thought that Snape was hinting at bribing him, and if there really was an idiot using this tactic, then he would definitely be punished for bribing the professor in addition to a score of zero.

"This is the recipe and the steps for today, and I hope you will be able to provide Mr. Filch with enough qualified Kling potions before the end of class."

With a wave of his wand, a flurry of materials and preparation processes appeared on the blackboard, and the students rushed to the medicine cabinet.

"Xana, the steps you took to deal with the white daisy are wrong, it's too broken. Professor Snape said it was enough to cut each petal to the size of a fingernail. ”

Hermione soon discovered that Xana's treatment was completely different from the one on the blackboard.

"I have my own solution to this potion, don't worry. Help me determine the concentration of snake bile, which requires 50 ml of 5% snake bile per 1000 ml of purified water. ”

"Huh? All right. ”

Hermione couldn't understand what Xana was really doing, it didn't feel like boiling potions but some kind of chemical reality.

Snape constantly patrolled the classroom, reprimanding someone who made a mistake in his approach, although it was essentially to correct the student's mistakes, but the other party's mistakes were more and more under the horrific venom spray, even the Slydrin students.

Neville was once again the target of reprimand, since the scabies potion accident in the potion class, he had suffered from a stern Snape phobia, and he usually practiced privately and occasionally got an A (passing grade), but as soon as Snape walked around the classroom in class, Neville was in a hurry.

"Mr. Mountbatten, is your head like this pot of blue-black dregs! How many times have I said that materials should be added according to the standard, are you afraid that if you add too much water, you will die of thirst!! ”

Snape, who had gathered his anger in a spin around Slydrin (scolding Gryffindor for being more relieved) grabbed Neville and pointed to the burned cauldron in front of him, spraying venom. The students shivered in the shadow of the bat, glad that Snape had caught not himself but Neville.

In the midst of Snape's stormy reprimand, another voice suddenly interjected, like a petrel in a storm, bringing a glimmer of light in the darkness.

"Hermione, 7 ml of Flobie Caterpillar Mucus add 50 ml of solvent No. 13."

Snape followed the sound and saw that Xana was taking a test tube from Hermione, intending to pour it into the cauldron. He walked over and pushed Hermione away, and looked inside Xana's cauldron, the potion inside had become viscous, and even more unexpected in color, Snape felt that he had never seen a student configure a Kling potion in this color in all his years of teaching.

"Pale yellow?"

"It's pale yellow! Miss Sakai, can you tell me why I turned pale yellow? Is your head as full of dregs as Longbottom! ”

"Professor Snape, please don't bother with my configuration, it's almost complete."

Snape's face turned ugly, darker than the bottom of the cauldron. After so many years, countless students trembled in front of him, and it was not without that kind of thorn in the resistance, but in the end they were all cleaned up (and the Weasley twins didn't dare to go straight to the hard top), and no one dared to ignore him so much.

"Stop! Clean up ......"

How strange is this pot of potions in front of him, Snape doesn't dare to let Xana do it anymore, many potions are not configured correctly, it is very dangerous, and strange products like this kind of bear children messing around may have some abnormal consequences.

Defenser

A mechanical voice sounded, and a brilliant protective magic array blocked Snape outside, Xana ignored Snape and poured the potion in her hand evenly into the cauldron, and as it was stirred, the original pale yellow potion gradually underwent some strange changes, and finally took on the blue color of the final product.

"Here, concentrated Kling potion. When using, dilute 1:30 before use. ”

Removing the magic and turning off the heat to bottle it easily, Xana handed the finished product to Snape, completely ignoring the other party's face as if it were the bottom of a cauldron.

"Sakai! You'd better give me an explanation!! ”

"Doesn't seem like I have anything to explain? The requirement for today's class is to hand in a prepared potion before class. Isn't this right in front of you, Professor? Xana's last word is also pronounced with a special accent.

"Explain it to me! Why don't you follow the steps I asked to prepare the potion? You're bold enough! Gryffindor's freshmen will be able to improve potions, so Professor Sakai will be able to teach it in the next class! Yes! ”

"Do you know what you're doing?!! Modify the potion recipe process at will, and you may lose your life at any time! And you stupid guy doesn't care about losing your own life, do you plan to lose the lives of a room of people! ”

"Urusse!"

"The entire improvement recipe and process have undergone rigorous computer simulations, and the actual results are completely consistent, not to mention that I have done safety precautions in advance. So I don't think there will be an irreparable accident. ”

Snape almost blew his lungs (he still didn't understand what Uruse was), but unfortunately he asked a lot of questions about the potion ingredients, and Xana answered them all fluently.

"Hell, I don't care what simulation you say, give me the recipe! Let me see that you have changed those things indiscriminately, and you are so lucky that you didn't blow yourself up! ”

Snape, who couldn't ask questions, finally planned to look at Xana's new recipe.

This time it wasn't entirely about picking bones in eggs, for some reason, Snape was going to teach Shana a good talent for potions (even though his teachings were seen by others as outright abusive).

"Barrow just passed by outside, Professor, are you looking for him?" Xana said a bad joke, "The recipe is here." But it doesn't work, I've already filed an owl patent for an improvement with the Patent Office. ”

The conversation between the two made all the students tremble, and the Gryffindor students all sweated for Xana. The classroom was quiet, and the Slydrin students covered their mouths and looked at Professor Snape as he read the parchment, the current Potions professor was like a volcano that could erupt at any moment, and no one wanted to be the unlucky guy who detonated.

"Suzu!"

The bell rang suddenly, everyone packed their schoolbags and ran out as fast as they could, and the students of Slydrin were the same, in the face of natural disasters, there was no need to keep the so-called aristocratic chanting, in case they were swept away by the terrible storm, they would end up in pieces.

Xana was not in a hurry, she tidied up and bowed slightly to Snape and walked out, Hermione was embarrassed to flee first as a tablemate, so she could only try to lower her sense of existence in the Yali Mountain on the side, and she didn't breathe a sigh of relief until she walked out of the classroom.

"Lily......"

I don't know how long it was, but a sigh came from inside the Potions classroom.
