The days of hanging out at Hogwarts

The green grass grows wildly, and the wind blowing through the wilderness already has the smell of autumn.

The little wizards were scattered on the grass, gathering in groups of twos and threes, squatting or sitting, staring boredly at the squirming little monsters. This is the content of their lesson, taking the snails for a walk and seeing if there is anything on the grass that they are willing to eat.

Bang!

The vaguely bluish white gunpowder smoke dispersed, and the pungent fishy smell spread. Several young wizards who were close to them hurriedly stood up and took several steps back. They waited until the smell was almost gone before gathering around again.

Loren squatted on the ground, holding a head soaking spell on his neck, and poked the soft little thing in front of him with a small wooden stick with great interest.

The bomb-tailed snail squirmed slowly, and the bulges on its body expanded and contracted one by one to move its body.

Loren poked the middle part of the snail's body, and it sunk in immediately. It was so soft that it seemed like there were no muscles or bones inside, and it was just fluid wrapped in a piece of insect skin.

Blast-tailed snails don't have a single bone in their bodies and rely on crawling to crawl. They should probably be classified as molluscs, but there seem to be signs of hardened shells on their backs. Maybe they will be arthropods in the future?

Loren glanced back. Professor Granger in the distance was still earnestly advising Hagrid. Hagrid, who was about three meters tall, had a humble posture, and Hermione, who was thin and slim, showed the majesty of the professor.

"..."

Poor Hagrid.

He lowered his head again and continued to observe this brand new creature.

Until the bell rang for the end of get out of class, the little wizards returned the squids to Hagrid one after another. Most of them were already half dead.

They have undergone some experiments with relatively extreme conditions, such as to see how many times the snail can spray at most, whether the snail can eat rocks, and how fast the snail can endure the rotation speed.

What bad intentions can the little wizards have? They just want to observe the project object carefully.

Hermione looked at the densely packed snails in the wooden box and felt fuzzy in her heart. She advised: "Hagrid, this won't work. Look at their size. In a few months, one of them can grow alone." It’s bigger than a wooden box, and it can blow up your wooden house casually.”

Hagrid picked up the box and walked towards the wooden house with a kind smile on his face: "No, when they become more sensible, I will teach them well... Aragog was like this when he was a child, with cobwebs everywhere. , as you will see later, they will be very well-behaved."

Hermione looked extremely distressed, while Harry and Ron remained silent and acted very calmly.

They were very open-minded. Dumbledore had approved it anyway, so why did they have any reason to object?

Loren followed beside him, and the bubble spell on his head had dissipated: "Hagrid, why can a manticore hybridize with a fire crab and still produce offspring smoothly?"

"Oh, Loren, actually I didn't expect that at first." Hagrid patted the box, "Their parents don't look like they can get along well, but who would have thought... probably their parents At that time, my mother felt that she should find a partner for herself, and then she fell in love with the Fire Crabs I placed next to her. Things like love are so unreasonable, but both parties are willing to do so, and I am happy to fulfill them. "

"You are in love with me?" Hermione couldn't help but complain, "You mean you are in love with me. Almost all the fire crabs that were bred were eaten. Is this love?"

"Well..." Hagrid said hesitantly, "There is such a thing in the forest. Mrs. Mantis will always eat Mr. Mantis. This is all to give birth to the next generation to inherit life."

"You are hopeless, Hagrid." Hermione felt very tired.

Following Hagrid into the cabin, they watched Hagrid light up the fire and felt the gradually increasing temperature and firelight. The snails in the box became excited and squirmed incessantly.

"Actually, I'm still more concerned about the issue of the union of different species of magical animals..."

Loren pulled up a stool and sat down, continuing the topic: "Completely different types of magical animals can produce offspring, and can stably inherit the magic power of their parents... This is completely different from us humans, not to mention wizards and Muggles. Combined, even wizards and wizards will produce squibs.”

Harry nodded thoughtfully: "My mother is a wizard, but Aunt Petunia is not a wizard... Colin's parents are both Muggles, but Colin and Denis are both wizards."

Thinking of Harry's two fans, Loren paused for a moment before continuing: "Did you notice? Magical animals don't have to worry about the inheritance of magic power at all."

"It sounds like a relationship between genetics and mutation..."

Hermione's parents were both Muggles, and they also felt about this kind of thing. By analogy, Hermione quickly thought of other phenomena: "Parents without magic may give birth to children with magic, but ordinary animals without magic will never No magical beasts will be born...

"The descendants of magical animals will basically inherit magic power. Not only the blood gestation, but also the hatching method of oviparous animals will have an impact, causing the magic power of the offspring to mutate."

Ron couldn't understand what they were talking about, parent-child, genetic mutation. His face wrinkled up, full of confusion: "It sounds like magical animals are closer to magic."

Hagrid reached behind his waist and scratched it. He felt that as a professor of Care of Magical Creatures, he could not quite understand what they were talking about: "Magical animals may not completely inherit their parents' magic power. If magical animals are combined with ordinary animals, The magic power of the remaining descendants will be weakened, and the magic power will be diluted like blood. If they reproduce for a few more generations, there will be no magic power left...

"The same is true for Crookshanks and Fang. They have the blood of magical animals, but they are just smarter than ordinary animals and can no longer use magic."

"It sounds very involved..." Harry was vaguely aware of the importance of this topic.

"Then it will be useful to have a clear study of the principle of the relationship between magic power and bloodline." Loren waved his hand, "Anyway, it is a very troublesome matter. We may not be able to understand it when we are too old to move."

"I see……"

Harry and Ron suddenly felt that this matter had little relevance to them, at least until they were too old to move.

Hagrid's head was dizzy, but he didn't want the students to think that he couldn't understand. He was silent for a while and said, "It's lunch time. Do you want to eat here? I've prepared rock biscuits."

"No, no, no..."

The little wizards quickly said that they had classes in the afternoon and would not waste time here. After Hermione gave Hagrid a lot of fire prevention precautions, the group left in a panic.
