HP: I just wanted to drop out of school, but I saved the world

But this lockdown seemed different from usual, more like a joint law enforcement operation.

She was taken by Snape to the third greenhouse, where Professor Sprout, who taught the Herbology class, was waiting for them.

When she saw Jian Yu, she happily walked up to her, hugged her warmly, and stuffed a few candies into her hands.

"Happy Halloween, kids!"

Jian Yu wanted to cry but had no tears.

Just before the Herbology class last week, she wanted to cause trouble so that the seemingly good-tempered lady would send her to the principal's office, so she released a flaming fireball at a Christmas cactus plant.

The Christmas cactus twisted and its snake-like tendrils burned in the fire and soon turned into ashes.

Just when she thought Professor Sprout was going to fly into a rage, she heard a voice:

"Five points for Slytherin!"

Jian Yu’s eyes went dark.

The gentle lady took out a stick insect-like creature from the ashes with great concern and gently comforted it:

"Don't be afraid, don't be afraid, it's okay."

It turned out to be a bowtruckle that mistook the dangerous devil's snare for a Christmas cactus, and was tightly entangled by its tendrils the moment it climbed up the branch.

When it was almost killed at the mouth of the net, a blazing fire saved it.

"Good boy, you must have reviewed what you are going to learn today, the knowledge about the Devil's Snare, before class."

Professor Sprout looked at her with emotion and said loudly to the students:

"Children, you must remember that the Devil's Snare usually disguises itself as a Christmas cactus to prey on creatures, but they are afraid of light and warmth! Therefore, when in danger, blazing flames or lighting spells are effective methods!"

Then she gave Jian Yu another 5 points for her erudition.

Jian Yu instantly became Professor Sprout's favorite.

So when Snape and she suggested taking Jane to squeeze the pus out of the Babo tuber, she happily agreed.

You know, if they were ordinary first-year students, she would never let them enter the third greenhouse!

Jian Yu observed the plant carefully. It was ugly, like a black, slimy slug wriggling in the soil. It had many pustules on its body and was slightly yellow-green in color.

"Miss Jane, wear your dragonhide gloves unless you want your hands to dissolve." Snape warned her.

Jian Yu's task was to collect the pus. As long as she aimed the bottle mouth at the pustules on the Babo tuber and gently squeezed and pressed, the yellow-green pus inside would spray into the bottle. The liquid was slippery and sticky, and exuded a pungent smell of gasoline.

But it is very effective in treating stubborn blackheads and acne. After being processed and made into a potion, it has a very good whitening effect and is often added to some cosmetics.

This task was easy for Jian Yu, as long as she was careful not to get the pus on her hands or in her eyes.

Soon, the large glass jar in the corner was filled with yellow-green pus.

But she had been thinking about causing trouble for a long time.

When Professor Snape was about to teach her how to deal with pus, she secretly apologized to the two professors in her heart.

Then she waved her wand and shot a blazing fire at the mouth of the large glass jar.

"BOOM!"

The pus of the Babo tuber is as flammable and explosive as gasoline. The moment the flame touched it, golden-red flames exploded in the greenhouse. The flames directly jumped to the top of the greenhouse, and the entire bottle turned into a burning fireball.

All the nearby plants started to burn, even their branches that had climbed up to the ceiling began to burn, and a quarter of the greenhouse turned into a sea of ​​fire.

Jian Yu felt guilty in his heart.

Burning down the greenhouse and destroying Professor Sprout's precious plants was enough to send her packing and returning home.

"Immobulus"

Two spells were chanted, and Professor Snape and Professor Sprout cast spells at the same time.

The flames went out instantly, and the greenhouse was covered tightly with layer upon layer of ice.

"How dare you--" Professor Snape was so angry that he couldn't speak, and his head was buzzing.

He never thought that Jian Yu would dare to ignite the pus in front of the two professors!

He brought Jian Yu here to let her learn more about herbology and potions, but she betrayed his expectations and trust and attempted to burn down the entire greenhouse!

Grabbing Jane's collar, Snape decided to go find Dumbledore immediately.

He couldn't stand this devil and continued to stay in his Slytherin house!

Either transfer to another hospital or drop out!

But Professor Sprout interrupted him.

"Severus, I think you should take a look at this."

She was examining the burned plants, which had been reduced to ash and piled up in pots.

However, they saw clusters of seedlings emerging from the ashes of the plants. These seedlings had thick roots and large green leaves covered with a layer of oily film. They grew at a speed visible to the naked eye under the two people's gaze. The trunk gradually became hard, the outer skin became rough, and the leaves became thicker and more numerous, looking very healthy.

"Yes, that's how it should be!" she exclaimed, as if she had discovered some new world.

Professor Snape frowned, staring at the rapidly growing plant in the pot, and looked at Professor Sprout in confusion.

The short witch with flowing gray hair smiled so much that the fine wrinkles on her face unfolded:

"These magical plants were shipped from Australia. I have been cultivating them in the greenhouse for a full month. They are still in the seedling stage."

"Now I understand, they are some eucalyptus plants. There are many wildfires in Australia, and these plants love fires. Every fire makes them grow rapidly!"

She walked towards Jian Yu and patted her shoulder gently: "Good girl, I know you have a good heart, but next time you do this, remember to tell me in advance. I almost misunderstood you."

Professor Snape had crouched down, examining the pus from the burned baboo tuber.

He put on his dragon-skin gloves and picked up a handful of ashes - no, it wasn't ashes, but a yellow powder with a strong aroma. He quickly sprinkled some on the back of his left hand, only to find that the waxy yellow skin was not corroded, but was quickly turning white.

It's... incredible, he looked at the back of his hand in shock.

You should know that these pus are undiluted and highly corrosive. Usually, when wizards use it to treat acne and pimples, they need to add a lot of water, but there is still a certain possibility of causing allergic reactions.

But just now, the back of his hand had directly touched the powder that had been burned by fire, and not only was there no damage at all, there wasn't even a slight allergy.

This is totally worthy of a new paper!

In fact, since Jian Yu entered school, he has invented methods for processing mantis shrimps, grinding color-changing giant snails, and so on. Each of them can be taken out and written into a twelve-inch long paper!

But this student loves to be lazy and hardly submits any paper assignments except the practical part of the course.

Even if it is submitted, it is full of typos and the grammar is terrible, which makes him want to give it a P just by looking at it.

Facing his deductions and confinement, she was like a piece of meat on the chopping block and he had no way to deal with her.

He raised his head and stared at Jian Yu with his cold and deep black eyes, as if he was thinking about something.

Finally he announced: "Write a ten-inch paper on the treatment and use of the pus of the babo tuber, due next week, to offset the remainder of your confinement for the semester."

......

After Jian Yu left, Professor Sprout complained to Professor Snape:

"Severus, forgive me for saying this, this child is really quiet."

"She never communicated with her classmates in my class, even though she had so many brilliant ideas."

"Perhaps you could guide her a little more. If she could communicate more, I wouldn't have misunderstood her just now."

After Dumbledore, this was the second professor to ask him this.

Maybe I should give this some more thought... he thought.

......

Jian Yu was carrying a large jar of yellow powder and walking towards the castle.

Snape agreed to let her take the powder back to do research and write a paper.

But the skin-rejuvenating and whitening properties of these powders occupied her mind.

Now she just wanted to find a bathroom quickly and put a mask on her face!
