Harry Potter’s Morning Light

  Chapter 1669 The Secret Word of the Goddess (14)

On the Scheldt River in northeastern France, there is a small town named Cambrai, cambrai, not cambray. It was the battlefield between Britain and Germany during the First World War. At that time, both Britain and Germany put a large number of tanks into battle. , And there are planes flying at low altitude.

I don’t know if people who dream of flying like a bird, and then invent all kinds of flying machines, would have thought that such a day would happen, according to Leonardo Da Vinci’s early unplaning of bird wings, and the right According to the results of the study of bird feather structure, the wings of birds are covered with thick tendon nets. Such a strong force can make them far exceed the force used to spread their wings and fly. They can be used to catch prey or escape hunting. In theory, they can be used to catch prey or escape hunting. The flight speed is increased by two or three times.

But the bird does not flap its wings when hovering in the air. Instead, it uses its wings to maintain balance. When the eagle wants to catch a hare on the ground, it will retract its wings to increase the speed of the dive, and wait until it is close to the target or close to the ground. Open your wings and grab the rabbit with your sharp claws.

  Another animal bat can also fly. It needs to flap its wings frequently to fly, but the flying height of a bat is far less than that of a bird. When it reaches a certain height, it will stop flapping its wings and open its periosteal wings to glide.

  The feathers of birds are soft and flexible, and it can pass the wind, while the wings of bats are completely impervious.

However, if you look closely, flying birds such as hummingbirds have almost no tails, and bats also have no tails, because the nocturnal creatures they prey always try to escape hunting by chaotic rotation. Bats must fly upside down and sideways. Use a variety of flight methods to deal with it.

  Birds usually fly upwards in a spiral or in a curve. If the wings of a bat have the same feather structure that allows air to penetrate, that kind of flight will kill them.

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

When the wind blowing over the top of the mountain becomes heavy and swift, the birds will follow the high wind from the slow wind into the high wind, and when the wind away from the mountain becomes soft and gentle, it is like the water in a narrow river flowing into the sea, and the birds Finding that their own power can control the wind, the birds will once again become dancers in the sky, performing various stunts in the air that make people standing on the ground breathtaking.

  In fact, boats floating on the sea also have something in common with bird flying, and sails also need to borrow wind. According to Leonardo’s narrative: I seem to be destined to talk about flying kites, because in the first memory of my childhood, there seemed to be a kite flying towards me in the cradle, prying open my mouth with the tail, and using the tail. Tap it in my mouth several times.

  This may be Leonardo’s dream, or his illusion. In short, when many Italian boys took merchant ships to trade in the Mediterranean, Leonardo chose a different path to become an artist.

  Iris is a symbol of the King of France. The shape of each petal of this flower is like iris and butterfly. Many people are fascinated by its romantic and feminine posture.

  The so-called mazarine in the Richelieu Library does not mean that this hall is decorated in the same dark blue as the Ravenclaw lounge.

After Richelieu, Cardinal Mazarin (Mazarin) became the Prime Minister of France. Mazarin also invested in the construction of a library like other politicians. Next to the French Institute is the Mazarin Library.

In the past, the Richelieu Library was a royal library. Mazarin once made great contributions to Louis XIV, but two years after Louis XIV’s reign, he was very "appropriate" to death, and the mazarin gallery became In the gallery of the mazarine hall, the two words mazarine and mazarin have similar pronunciations and only have an e difference, but they have completely different meanings. In this way, it is appropriate to express the respect of Louis XIV to this hardworking minister.

  The nobles in the Middle Ages called themselves "blue blood". They took pride in rolling up their sleeves and seeing the clearly visible blue blood vessels on their snow-white forearms. After the library is built, the manuscripts must be put in. As the main sponsor of the library, the sponsors have their own salons here, which can host banquets to entertain scholars, chat with them, discuss academic studies, and there are also many tableware , You can hold a dinner party.

Severus followed Iger to a rectangular hall at the end of the dark blue hallway. Next to this hall is the oval hall. In this hall there is a door to the bookshelf on the third floor of the oval hall, without using it with other readers. An entrance is usually closed and only opened when "special guests" come.

There are a lot of things that can’t be bought just by having money. You have to have access. The manuscripts obtained by privately-run collections booksellers are of unknown origin, and the asking price is too high, relying on the government’s funding alone. Where can I afford it?

A good library must not only have beautiful buildings, but more importantly, the collections. If the manuscript of the Declaration of Independence in Severus's hands is genuine, the library placed in a small place is the treasure of the town, even if it is The French National Library is also not an ordinary collection, especially after the new library has moved a large number of manuscripts and collections from the old library, the Richelieu branch needs to replenish fresh "blood" to restore its vitality.

  At this moment, he and Iger were standing on the top floor of the oval hall overlooking the library. Near the closing time, the readers all left one after another. The whole hall was empty, without the excitement of the day.

  In the past, the central library was dug down two floors in 1930 in order to expand. At that time, people were still worried that something would be dug, but nothing happened later. Therefore, the rumor that there is a secret room under the library and that a monster is hidden in it is regarded as nonsense.

  Napoleon must have died when the oval hall was built. As for the reading room of the library when he had no money and power, it seemed like an eternal mystery.

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

   "Impressive." Severus said, looking at the city bronze medals on the Oval Hall, even standing on the top floor, they were still too far away.

  "Do you want to go upstairs?" Iger asked, "I can also ask the maintenance personnel to take you upstairs."

  Severus did not make a sound. Each of these bronze medals corresponds to a circular ventilation window, and each ventilation window is between two pillars. There is something similar to a fire hydrant beside the pillars.

   "What is that for?" Severus asked, pointing to the "fire hydrants."

   "That's the vent, used for heating." Aiger said.

   "There was a monster's voice inside?" Severus asked deliberately.

   "I will notify you if I hear it." Aiger said with a smile.

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

   "Of course." Iger said, but he kept looking at Severus.

  Severus handed her the manuscript of the Declaration of Independence protected by a transparent rubber board.

   "Thank you, we will return it to you soon after the inspection." Iger said with a smile, took the manuscript, and then left without reluctance.

  Severus took out the wand from her sleeve after watching her back disappear.

   "Revealyoursecrets."

  He said softly, and then a burst of white smoke sprayed from the end of the wand and spread to the whole hall.
