Chapter 2517 man on a mission (10)

"Good afternoon, Professor Sprout."

When Pomona was passing by the school foyer carrying a picnic basket, she happened to meet students going to the auditorium to eat.

"Good afternoon." She responded with a standard smile, and then she heard the sound of "ding, dong, dong, dong, dong, dong, dong, dong".

She looked up following the voice and found that it was Filch standing on a very high, shaky ladder, driving nails into the wall with a hammer.

Due to the constraints of the magical contract, house elves cannot touch wizard portraits, so when the portrait on the wall becomes loose, Filch has to climb a dangerous ladder to adjust it.

It was just a trivial matter at first, but as soon as she thought of the hairy crabs in that room, she immediately became furious.

The trophy room is also on the third floor. Each of the trophies displayed in it has been polished to sparkling glory by the students who were punished. But why did he forget to lose the wand storage room?

"Mr. Argus Filch," Pomona said, looking up at the bottom of the stairs. "Can you come down for a moment?"

Filch stopped hammering and looked down at Pomona.

"If you have any questions, just say so. I still have a job," Filch said.

"I think it's dangerous to talk like that," Pomona said.

"No, it's really dangerous when I go down and talk. Every time someone calls me by my first name, it means I'm in trouble."

Pomona put down the picnic basket and folded her hands.

"You have patrolled so many times, have you ever been to the lost wand storage room on the third floor?"

Filch recalled it for a moment and nodded, "Yes."

"Then describe to me the last time you went there and what you saw?" Pomona asked.

"Everything is as usual." Filch said, waving the hammer. "Every wand is neatly arranged. If you put a box on them, they would be the same as those sold in Ollivander's shop."

"Oh~ Really?" She squinted her eyes, "Why is it different from what I just saw?"

"The last time I checked that room was three years ago." Filch said as he hammered the nails. "In the first year, the principal ordered the fourth floor stairs to be closed to traffic, including me. I think you know why.

I usually go down the stairs on the fourth floor and go to the storage room on the third floor to check. The next year, my cat, Mrs. Lorris, was petrified, and I could only patrol the entire school, not to mention

The Defense Against the Dark Arts professor that year was Gerald Rohart. He told me that I would be safe with him at Hogwarts. He also gave me a letter of introduction and asked me to teach Squib Magic.

School."

"Oh." Pomona put down his hand.

"In the third year, that is, this year, a troll security guard was finally added." Filch hit the nail hard, causing the dust on the wall to collapse, scaring the surrounding portraits. "But except for Wes

Twins, Harry Potter seems to be following his father's example of wandering around the castle at night. Maybe I should prepare a file cabinet to store the school rules he violated like his father did in the future. If they can be more calm,

Maybe I can take time to check the room you just mentioned. Is there anything else you want? Madam Dean."

"No." Pomona picked up the picnic basket and waved towards Filch, "I wish you a good day, Mr. Filch."

Filch ignored her and continued to hammer in the nails.

Pomona shook his head as he walked. Fortunately, the troll security guard only needed food, not wages, otherwise...

"Hahaha~"

Peeves flew over Pomona's head, and his target seemed to be Filch, who was teetering on the ladder.

"Peevis!" she shouted angrily. Filch would be hurt if he fell from such a height.

However, Peeves didn't care so much and circled around Filch. Filch held on to the frame of a painting on the wall to prevent himself from falling off the ladder.

Just as Pomona was about to take out her wand, Slytherin's ghost Bloody Balor happened to pass by. Peeves immediately seemed to have seen something scary and flew down the stairs to the fourth floor.

She breathed a sigh of relief and was about to turn around and leave when she suddenly noticed a footprint in the dust on the ground.

The dust fell when Filch was hammering nails, and there were no students passing by around. Then she raised her head and saw no third person in the hall besides her and Filch.

"Come down after nailing it." She said to Filch, and then left the castle as if nothing had happened, walking along the wooden bridge towards Hogsmeade.

==================================================

============

Corpus Christi took Georgiana to his office.

There are many sketches of biological anatomy and rock fossils on the wall of this office, but the most eye-catching one is an aquarium placed in the corner, which contains a strange green fish. It is 18 inches long and has a head

It is flat, with a slender body and hollow fins on its back.

She couldn't help but walked over curiously and asked, "What is this?"

"The Nile polyfin fish, the Egyptians call it bee-sheer. This fish can survive in rivers and swamps. Look at its scales." Saint Rael pointed to the scales on the fish. "It looks like

Not like a snake?"

Georgiana observed carefully. She had heard about the theory of evolution, and the fish in the water gradually came to the shore and turned into amphibians. This fish seemed to confirm this conjecture. The scales on its abdomen were like snakes.

It helps the snake crawl. At the same time, this fish also has external gills, which means it can also be aquatic. The key is that it is still freshwater.

"What an extraordinary discovery, Mr. Saint-Hilaire." She said sincerely, "You have made a contribution to human civilization."

"I think it's my turn to compliment you, madam." Saint-Hilaire sighed. "I'm sorry that I spoke to you like that."

"Is this the show you prepared?" Georgiana said with a smile.

"Not exactly." After Saint-Hilaire said, he walked to the bookshelf, took down a particularly beautifully bound book from it, and handed it to her.

"What is this?" She took the book and flipped through it.

"The A Brief Book of Egypt contains what we discovered during our trip to Egypt this time. It has not yet been officially published. This is the first batch of sample books." Saint-Hilaire said.

"Are your fish recorded in the book?"

"Of course."

Georgiana placed the open book in front of Saint-Hilaire, and he flipped through it quickly, quickly finding the sketch of the "Archaeolus".

"It's unbelievable." She looked at the sketch and then at the living fish. "Archaeopteryx" has become extinct, but this fish has survived and still maintains the shape it had millions of years ago.

A living fossil.

"Do you have an anatomy diagram of this fish?" she asked again.

Saint-Hilaire turned around and found a rolled-up colored pencil sketch from a leather scroll.

It is said to be colored pencil, but in fact the respiratory system of the fish is depicted with red pencil. Its swim bladder forms primitive lungs, which can not only fill it with a large amount of air, but St. Tirel just said that this fish can survive in the swamp.

To survive, the oxygen content in the swamp is not high.

She had heard before that the water in the Nile River is very turbid and needs to be clarified before drinking. The respiratory system of this fish with external gills and lungs can adapt to this environment. When the oxygen in the water is not enough, it will go to the surface of the water to breathe, just like rain.

Just like the fish in the previous pond.

"This kind of fish can live out of the water for two days. I put a piece of wood in the water, and sometimes I find it lying on it." St. Tirel looked at the driftwood on the water and said, "If I had only found this in Egypt

Species, it will compensate me for all the pain of this long journey."

Georgiana followed him at first, and then out of the corner of her eye she spotted a painting on the fish tank.

It was a group portrait. At first she thought it was an expedition, because the people in the painting were all wearing different clothes, and some even had missing legs that were replaced with wooden legs, or their faces looked like pirates.

Blindfold.

But she soon discovered Bonaparte, who stood prominently in the center of the painting. He looked like an adventurer.

"This person is Malu." St. Tirel pointed to a person's head and said, "He is an engineer now, and he is interested in the lens invented by that child."

"I've heard of this." Georgiana looked at the portrait and said, "But Fresnel didn't invent that lens."

"I know." Saint-Hilaire looked at her, "Because you are a foreigner, no one will question you when you mention Condorcet."

"What?"

Saint-Hilaire didn't want to mention it. He pointed to the head of another person and said, "This person is Borier. You may know him..."

"Why should I know about him?" Georgiana asked, and then she realized that her question was silly.

"Have you not been to the Alps? He is a high-ranking official in the province of Grenoble, and that place is an important transportation thoroughfare." St. Tirel said, "Last time Ney went to Switzerland, didn't you cooperate?"

"So Beaulieu met Fresnel because of me?" she asked.

"This child's mathematical talent is famous throughout the school, and it's not entirely because of you." St. Tirel shook his head. "And Beaulieu and Malu are both supporters of the light wave theory. In Mechelen

I saw what the child wrote on the blackboard. He is also a supporter of the light wave theory, right?"

"I can't understand what he wrote," Georgiana replied.

"I think they will be interested in his research. Malu has also conducted research on optical phenomena in Upper Egypt before."

"About what?" she asked curiously.

"The non-existent oasis appears in front of the lost people, allowing them to exhaust their energy for the illusory goal and eventually die in the desert. This is an act of God for the Egyptians."

She remembered that this was a mirage. Bonaparte encountered it on his way back to Cairo from Jaffa. He himself could recognize it as a mirage, but the camels could not. Those thirsty camels ran towards the mirage and later drank it.

The salt water was dead, almost taking Bonaparte with it.

But he was lucky and finally returned to Cairo safely.
