Chapter 1669 The Goddess’s Secret Word (14)

On the banks of the Scheldt River in northeastern France, there is a small town called Cambrai, c-a-m-b-r-a-i, not c-a-m-b-r-a-y. It was the battlefield between Britain and Germany during World War I. At that time, both Britain and Germany put a large number of tanks into the battle.

, and there were also planes flying over at low altitude.

I don’t know if people who fantasized about being able to fly like birds and then inventing various aircrafts thought that such a day would happen. According to Leonardo da Vinci’s early anatomy of bird wings and his analysis of

According to the results of research on the structure of bird feathers, the wings of birds are covered with thick networks of tendons. Such strong strength allows them to far exceed the force they usually use to spread their wings and fly. They can be used to catch prey or escape pursuit. In theory, they can

Flying speed is increased by more than two or three times.

However, when the bird is hovering in the air, it does not flap its wings. Instead, it uses its wings to maintain balance. When the eagle wants to catch a hare on the ground, it will fold its wings to increase the speed of its dive, and wait until it is close to the target or close to the ground.

Open your wings and catch the rabbit with your claws.

Another animal, the bat, can also fly. It needs to flap its wings frequently to fly, but the flying height of bats is far lower than that of birds. When it flies to a certain height, it will stop flapping its wings and open its wings with only periosteum to glide.

Bird feathers are soft and flexible, and can be ventilated, while bat wings are completely airtight.

However, if you look closely, you will see that flexible flying birds such as hummingbirds have almost no tails. Bats also have no tails, because the nocturnal creatures they prey on always try to escape pursuit through chaotic rotations. Bats must sometimes fly upside down and sometimes sideways.

Use various flight methods to deal with it.

The flight of birds usually spirals or curves upward, and if bats' wings have the same feather structure that allows air to penetrate, such flight will kill them.

Wind is an important element in the flight movement of birds. When a bird is in the wind, it can hover in the air even if its wings do not move. The moving air lifts the bird. When the wind stops, the bird lifts itself by flapping its wings.

When the wind blowing over the mountain top becomes heavy and fast, and changes from slow wind to strong wind, birds will follow the strong wind. When the wind blowing away from the mountain becomes gentle and gentle, like water in a narrow river flowing into the sea, birds will

After discovering that they can control the wind, the birds will once again become dancers in the sky, performing various stunts in the air that will amaze people standing on the ground.

In fact, ships floating on the sea have something in common with the flight of birds, and sails also need to borrow wind power. According to Leonardo's narrative: I seem to be destined to talk about flying kites, because in my first memory of my childhood

, as if a kite once flew towards me in the cradle, pried open my mouth with its tail, and slapped it in my mouth several times.

This may be Leonardo da Vinci's dream, or perhaps his hallucination. In short, while many Italian boys boarded merchant ships to trade in the Mediterranean, Leonardo da Vinci chose a different path to become an artist.

The iris is the symbol of the French king. The shape of each petal of this flower resembles both an iris and a butterfly. Many people are fascinated by its romantic and graceful posture.

The so-called dark blue hall (mazarine) in the Richelieu Library does not mean that this hall is decorated with dark blue everywhere like the Ravenclaw lounge.

After Richelieu, Cardinal Mazarin became the Prime Minister of France. Like other politicians, Mazarin also invested in building libraries. Next to the Collège de France is the Mazarin Library.

The Richelieu Library used to be the Royal Library. Mazarin once made great contributions to Louis XIV, but he died "appropriately" two years after Louis XIV took office, and the Mazarin Hall became

Mazarine Hall, the two words mazarine and mazarin have similar pronunciations and only differ by one e, but they express completely different meanings. In this way, it appropriately expresses Louis XIV's respect for this hard-working minister.

The nobles in the Middle Ages called themselves "blue blood". They were proud that when they rolled up their sleeves, they could see the clearly visible blue blood vessels on their snow-white forearms. After the library was built, they had to put manuscripts in it as a library.

The main sponsors of the museum have their own salons here, where they can hold banquets to entertain scholars, chat with them, and discuss academic matters. In addition, there are many tableware here for holding dinner parties.

Severus followed Egger to a rectangular hall at the end of the dark blue hall. Next door to this hall is the Oval Hall. There is a door in this hall that can lead to the bookshelf on the third floor of the Oval Hall. It does not need to be used by other readers.

An entrance is usually closed and will only be opened when "special guests" arrive.

There are many things that cannot be bought with money alone, but also with connections. The manuscripts obtained by private collectors' booksellers are either from unknown sources or because the asking prices are too high. They only rely on the small amount of funds allocated by the government.

Where can I afford it?

A good library must not only have beautiful buildings, but more importantly, its collections. If the manuscript of the Declaration of Independence in Severus's hand is authentic, a library in a small place will be a treasure, even if it is

The National Library of France is no ordinary collection. Especially after the new library moved a large number of manuscripts and collections from the old library, the Richelieu branch needs to add fresh "blood" to restore its vitality.

At this moment, he and Egger were standing on the top floor of the oval hall, overlooking the library. It was approaching closing time, and the readers had all left one after another. The entire hall was empty, without the bustle of the day.

In order to expand the Central Library, two floors were dug down in the 1930s. At that time, people were worried that something would be dug up, but nothing happened. Therefore, there were rumors that there was a secret room under the library and that there was a monster hidden in it.

was regarded as nonsense.

Napoleon must have been dead when the Oval Hall was built, and it seems to be an eternal mystery as to which reading room of the library he often used to warm himself by the fire and read when he had no money or power.

"What do you think?" Egger asked Severus with a smile.

"Impressive." Severus said, looking at the city bronze medals on the oval hall. Even from the top floor, they were still too far away.

"Do you want to go upstairs?" Egger asked. "I can also ask the maintenance staff to take you up for a visit."

Severus remained silent. Each of these bronze medals corresponded to a circular ventilation window. Each ventilation window was between two pillars. There was something similar to a fire hydrant next to the pillar.

"What are those for?" Severus asked, pointing to the "fire hydrants".

"That's a vent, used for heating," Egger said.

"Are there any monster noises coming from inside?" Severus asked deliberately.

"I'll let you know if I hear it." Egger said with a smile.

Severus patted the railing, "I want to walk around alone."

"Of course." Egger said, keeping his eyes on Severus.

Severus handed her the manuscript of the Declaration of Independence, which was protected by a transparent gum sheet.

"Thank you, we will return it to you soon after the inspection." Egger said with a smile, took the manuscript, and left without any regrets.

Severus watched her back disappear before taking out his wand from his sleeve.

"Reveal your secrets."

He whispered softly, and then a burst of white smoke spurted out from the end of the wand and spread to the entire hall.

That hall can no longer be found. It was demolished during renovations in 2017.
