HP: For a better world

"And the Swelling Spell - don't try to scare me."[1]

Hermione tickled her, "Don't change the subject, come and help me promote~"

"Stop~ It's itchy! Itchy!" Jenny resisted for a while, but couldn't hold it anymore. She laughed out loud and was pressed on the chair to be tickled.

"Help, hahahaha." Jenny was unable to dodge and laughed so hard that she couldn't breathe. Seeing Hermione's smug look, she fought back on the spot and pushed Hermione down to sit down, and they tickled each other.

The two girls burst into laughter.

"Okay, okay." Jenny's face turned red with laughter. She took a few breaths and quickly escaped from Hermione's hands.

"Stop it, Madam Pomfrey will hear us and scold us -"

Jenny said with a red face and sweat from laughing. She glared angrily at the student who secretly opened the curtain to peek at them, and then quickly closed the curtain again for him.

Seeing that there was no chance to escape, the student wailed and could only lie down again.

"What's wrong with him?" Hermione asked casually, glancing at him.

"Professor McGonagall found the antidote for the quick-acting skipping candy on him. As a punishment, he has to stay in the hospital wing for a whole day until the next morning." Jenny said, "It seems that the Weasleys are not able to defend against the professor's flying spell."

"…But that's even more exciting," Hermione pouted, "Those boys take turns betting on who will not be discovered by the professors. I dare say Professor McGonagall will soon get tired of this and ask the headmaster to put their goods on the Hogwarts banned items list."

"Oh... great publicity." Jenny said with a subtle expression.

"Don't change the subject," Hermione said coquettishly, shaking Jenny's hand, "Come and help me promote it?"

After staring at each other awkwardly for a while, Jenny relaxed, "...I will help you mention a few things to them when I am free in the medical wing. For more...I don't know if I will have time..."

"Really? That's great—" Hermione said impatiently, "I mean, when are you free?"

"...Now?" Jenny looked around guiltily and muttered, "You can't say you're free in the medical wing."

"Jenny--" Madam Pomfrey came out from behind the curtain angrily, "What are you doing? Stop being lazy. Where's the bottle? Come and help!"

“Uh…” Jenny scratched her hair and hurried over. “I’m going to help first. You should go back soon! I’ll remember to talk to them about your Elf Rights Association when I have time!”

"Eh?" Hermione reached out to hold her but failed. She watched her roll up her sleeves again and run up and down the medical wing. She puffed her cheeks and sighed silently.

Two weeks later.

Defense Against the Dark Arts class.

"I got some interesting news from my old friend," Moody's wooden legs tapped across the ground as he stepped onto the podium. Every time he opened his mouth, his wooden legs tapped out a short tone on the floor: "Prophecy... Statute of Secrecy... New breakthrough in werewolf treatment. Oh, the world is changing. People are beginning to turn their attention to other races. It's becoming increasingly difficult for MACUSA to cover up the Statute of Secrecy... Can they really do it? I'm not optimistic, but so far, they've done it - but you should always be prepared."

he shouted.

There was total silence in the audience as no one dared to boo.

"There are fewer and fewer wizards who can serve as Aurors because of some well-known curses... I have discussed this with Professor Dumbledore, and we both agree that we should let you come into contact with some more dangerous things in advance to avoid being overwhelmed when you actually encounter them."

He brought out a large box covered with a velvet curtain.

He waved his wand again, pointing at the tables and chairs in the classroom.

The tables and chairs on both sides floated up and moved to the back, hitting the buttocks of the students in the back row violently amid their screams until they were all pushed to the front, and then they fell down quietly.

There was only one desk and chair left in the entire classroom, placed in front of the podium at the front.

Moody's hoarse voice rang out.

"I found the Misuse of Muggle Artifacts Office and borrowed a... well, little malice towards Muggles."

"However," Moody said, "They haven't figured out what's on this thing yet... I can only ask you to confirm the effect of this spell." Moody said slowly, "Rather than letting me determine the effect alone, I think it will be faster if you come together...

"The only thing I can guarantee is that there are three magic items in this box... The spells on them are all Imperius Curse." Moody nervously twitched his mouth, as if trying to show a harmless smile, but he obviously failed. The magic eye swirled around in his eyes, "Come closer!" He stamped his feet and emphasized.

The students came closer.

Moody patted the wooden box. "There are two items left in this box. One of them - you have all seen it. It was made by me. It will make you jump onto the table. There are many tables in Hogwarts. You will easily find that you have been tricked."

"There is another one bought from Knockturn Alley... They have been stored for too long, so the spell effects of these simple props are prone to errors... making them more dangerous..." Moody said lightly, "It all depends on your luck. I can only guarantee that you won't die in the process."

"If anything goes wrong, Madam Pomfrey will hold your life."

Some people couldn't help but shrink back.

"Of course cowards can retreat." Moody glanced down with contempt. "There are always people who want to wait until they are in real danger before trying to dig out what I taught them from their brains."

"Let me see if there are any cowards in Gryffindor and if there are no lack of warriors in Slytherin... Only those with strong wills can get my reward in today's class."

"I heard some people like my stories about catching dark wizards?"

There was a low chorus of responses from below.

Moody took out a spyglass. As soon as he opened it, the spyglass started beeping. He frowned in annoyance, then roughly inserted his fingers into the joints of the spyglass and pressed a few times to turn it off: "...It's a bit noisy. These spyglasses will beep once they detect lies and traces of dark magic, so don't think about pretending to touch the props later...It will tell me your lies...It's very sensitive and a hero! I once used it to chase a group of dangerous dark wizards in the desert-it saved my life in danger." Moody fiddled with the spyglass, pushed it to the most conspicuous place on the podium with a finger and said, "It seems to be a little broken...You can keep it as a souvenir...I will only give it to the most determined person-"

"Anyone who successfully resists in this class will also win ten extra points. Remember to tell me what the voice in your head that keeps persuading you to do... There are people waiting for me to tell him the result." Moody grinned.

Then he clapped his hands and said, "Alright, line up. Everyone must touch it at least once today. Those who are capable can come more than once. Line up in three lines! Remember! You can only touch one item at a time!"

"The effect of multiple spells," Moody grinned, his eyes sparkling with interest, "I believe no one would be willing to try it... Potter! Professor Dumbledore said he wants to train you more - you come first."

Note [1]: In the original work, the Magnification Spell and the Growth Spell are the same spell name, but the effects are different. One increases size, and the other increases age. Please read the original text in the comments section after quoting it.

My personal inference is that the Growth Charm can make plants grow quickly, consuming all the nutrients they need in the process. So Hagrid did not ripen them directly.

The English translation of the Growth Spell we know is the Expansion Spell, which is the same as the Amplification Spell. At the banquet that year, there were not too many pumpkin products (Harry went to Nick's birthday party, so the argument is not clear). After searching, it was found that there is indeed a giant pumpkin crop that can grow to several times its original size within three days, but if it is too large, the pumpkin is easily crushed and cracked, and the taste is poor and too much water. Some varieties are poisonous and the seeds are scarce. It is usually used to carve giant pumpkin lanterns. The variety is the giant Atlantic pumpkin (which can weigh more than a thousand pounds) (some say that it has too little water and tastes good, but I haven't tasted it myself, so I took more results. It is too watery and tastes bland. B station has tasted the video and said it has no taste) In addition, the giant pumpkin needs multiple vines to feed and a huge amount of fertilizer. If the pumpkin is as big as Hagrid and three people, the land may be ruined if the Growth Spell is used without fertilizer (x) The feces of magical animals should be used. There is also the problem of flower pollination. If the Growth Spell allows a plant to grow directly to maturity, the cross-pollinated crops may not even grow much to eat...

In addition, the staple food of Hogwarts is still starch products such as bread, potatoes, and beans. Hogwarts does not have large farmland, so a large amount of flour and potatoes are imported from outside. There should be reserves. Flour can be stored for about 1-2 years, and sealed for longer. The wizarding world does not have vacuum plastic sealing and canning, so it is stored at low temperature. Potatoes can be stored for three months to a year in this case, dried chickpeas can be stored for 3 years, and raw beans can be stored for 1-2 years. Leafy vegetables are stored for 1-3 months, and apples are stored for 6-7 months. In other words, in terms of eating alone, Hogwarts has food reserves and can last for a year without new sources. In addition, ordinary animals in the Forbidden Forest may be able to eat some fresh meat without damaging the environment. But the relationship with the intelligent species in the Forbidden Forest and Black Lake will definitely deteriorate (there is also a group of expanding giant spiders). In addition, there are medical supplies such as herbal potions and teaching needs, and large-scale growth and fertilizer needs. In order not to damage the soil, land planting takes time. Hogwarts can be self-sufficient within a year, but there will be problems with the richness of the diet. If it exceeds a year, they will have to go out to find supplies... I didn’t calculate the fuel because of the magic fire... There is also the issue of the area of ​​the ridges... The law of conservation of energy should also require soil to simulate the weather before planting. Uh, my head is imprisoned by Muggle thinking and there is no hope... I think too much, if magic really exists, it would probably be like this... Even if there is scientific truth behind it, it is easier to achieve if you don’t delve into the spells... So Winster is only 12.3 or years old, the age with the richest imagination, and his understanding of Muggle knowledge is not in-depth... I’m getting off topic.
