Chapter 1930 Under the Lion’s Claw (12)

Compared with the gorgeous bindings in France, the bindings in the UK are relatively simple and cheap. This may be because British documents focus more on dissemination than collection, and ordinary people cannot afford bindings that are too expensive.

Vellum binding is more common among British bindings. This kind of binding can be regarded as "ordinary" and "cheap" binding. During the Renaissance, vellum replaced vellum and became a common writing and printing material. The 1966 Florence flood caused

More than 300,000 precious ancient books were destroyed. At that time, almost all the books were submerged in water and soaked in mud and oil stains. However, there was a kind of book floating on the water that survived.

These "survivors" are "cheap bindings" with vellum covers. Although vellum also absorbs water, this simple binding does not have wooden boards or cardboard on the cover, so it is generally lighter and floats easily on the water.

Of course, you can't find a book with this kind of binding in this rare book store. Severus took a book from the bookshelf. It was actually a glass cover. To be precise, it was a plant specimen. Under the thin glass was

A chervil, this flower is so common that it is sometimes called the pincushion flower, or the bride of the morning.

He opened the page and found that it was a book about botany, with very exquisite plant illustrations. However, when he opened another page, it was about the Rose Window. When he turned it over again, he discovered that human beings

of the skeleton, while behind it is a drawing of the Eiffel Tower.

He had to stop and read carefully.

The Crystal Palace that held the first World Expo was based on the bottom pattern of Wanglian. Its solidity is due to its densely distributed leaf veins, which are connected from the sides. The plant tissue covering these leaf veins is not tight, but wrinkled.

The designers of the Crystal Palace took advantage of this structure, where the steel and glass were not placed completely flat together.

The Eiffel Tower also imitated nature, a human femur to be precise. Although the Eiffel Tower is named after Gustave Eiffel, its designer was Maurice Kocherland, a young Swiss engineer under him.

To solve the problem of weight distribution of the giant crane skeleton, he consulted his Swiss compatriot Karl Kuhlmann, who had just proposed a construction method that imitated the human femur.

While Kuhlman was racking his brains to think about the problems plaguing Koshland, a Swiss anatomy professor visited him. In fact, the femur is equivalent to the cantilever of the spine, and the spine is connected to the femur by a hinge. When viewed closely,

You will see multiple bundles of fibers, which can shunt the lines of force generated by the body's weight, so they can stably distribute the vertical gravity to the horizontal direction. By calculating and simulating the distribution of femoral bone fibers, Kuhlman successfully created a constructable

Tower crane.

There is no evidence of how the Church of Santa Maria del Fiore in Florence was successfully built, especially the design of the crane. Severus could understand this article because it was written in German, and Wang Lian was actually very

There are two types, one is the Amazonian royal lotus and the other is the Victoria royal lotus. The Amazonian royal lotus was discovered in a tributary of the Amazon River by a German botanist named Haenke in 1801.

of.

Compared with Victoria Lotus, which is produced in Argentina, Amazon King Lotus prefers a warm climate, and its petioles are covered with thick and dense thorns, and the flowers are more colorful than Victoria Lotus.

Germans like popular science very much, so Severus bought this book without much thought. He still remembered what Paul had told him about the idea of ​​building a Crystal Palace in St. Cecil's Church.

The Crystal Palace was not that easy to build. Even if it was built of glass and steel, could qualified steel be cast with the metallurgical level of the early 19th century?

He held the "specimen" between his arms and continued to search among the bookshelves. He soon found a book bound in dark green Moroccan sheepskin, and he took it out of the book.

Napoleon's expedition to Egypt was a failure, but he brought ancient Egyptian civilization to Europe. At that time, he asked many scholars to compile a book.

He used a very gorgeous binding. Even if the book in Severus's hand was not the first edition, it was relatively early. In short, Napoleon Bonaparte used the splendid splendor of ancient civilization to cover up his failure.

Severus sneered and accepted the book. He took the two books in his hand and the previous Decameron to the counter to check out, as if what he bought was not a rare book but a rare book.

I went to any bookstore and browsed around.

The clerk knew that he had met a big customer and was eager to serve him with a smile on his face.

Both banknotes and books were made of paper, but these three books required about a briefcase of banknotes to take away. However, Severus used gold bars to pay the bill, which surprised the clerk.

"You can find someone to estimate it." Severus said, "I can wait for you."

The clerk quickly picked up the phone. At the same time, Severus continued to wander around the bookstore unhurriedly, but this time his eyes were more focused on the opposite side.

The turmoil caused by the "Carnival of Animals" will not last long, even with the giant beast Gevaud.

Appetite is the most biological instinct, but the basilisk is a weapon. It is essentially similar to a tank, except that the tank burns oil and needs to be refueled, while the basilisk wants to eat rats. Once the basilisk dies, Hogwart

There are more rats in Ci.

Destruction and killing are the instincts of the giant beast of Gevaudan, but Severus has strengthened its instinct to escape. When attacked, it will not roar like a normal beast, but will run away. Even if its strength is not as strong as before, it will

The French Ministry of Magic and the Aurors have enough to keep busy.

Just when Severus was thinking of countermeasures, the store door was opened again, but no one was seen. Severus lowered his head and found that it was a dwarf who walked in.

Not only wizards make disguises, but also goblins. This goblin who looks like a human dwarf and Severus looked at each other and immediately recognized each other's identities.

"Good evening, Mr. Bow-legged." The clerk stood up and said, "Please help me take a look at this gold."

The bad-tempered goblin stared at Severus rudely for a while, walked behind the table, and climbed to the edge of the table like a mountain.

Severus couldn't help but laugh when he saw him.

"Why are you laughing?" the goblin bow-legged said viciously.

"Nothing." Severus said frivolously, no longer looking over there, but continued to look across.

The French goblin and the Muggle clerk were whispering in French, although he couldn't understand what they were saying, and he didn't expect it to be anything good.

The goblin carried a small box with him, which contained scales and weights, and he quickly weighed them.

"It's all true." Bow-legged curled his lips and said, "You still want to make up for it."

"No, you can keep it." Severus said, then picked up the rare book on the table and left the bookstore.

He did not go to Luxembourg, but returned to the carriage. Orlando had already left, and only Kreacher was still waiting by the carriage.

"Put these books in the study." Severus handed the rare books he just bought to Kreacher. However, before he could finish what he said, a puff of black smoke flew over his head.

All the lights in the place where it flew were turned off, and it seemed to be carrying endless darkness as it flew straight towards Luxembourg.

"You will come back later after you open the entrance and drive the carriage in, so you don't have to come." Severus said, "You stay here and play it by ear."

"Yes, sir," Kreacher said, watching Severus disappear around the corner.

Luxembourg cast defensive magic on the outside, and Black Smoke broke through two or three times without a breakthrough, but those hidden Aurors appeared, and they pointed their wands at Black Smoke.

Severus raised his wand, and with a flash of white light, the defensive magic disappeared.

This is a curse created by Voldemort. It is the same spell he used when he destroyed the school's ancient defensive magic in the Battle of Hogwarts. However, Severus's blow is not at the same level as Voldemort's in terms of intensity.

.

As he said in the dock, he was still extraordinary, but the performance of the Elder Wand made him feel disappointed.

After the defensive magic disappeared, the Aurors were a little panicked. They divided into two groups, one to deal with the Obscurials flying in the sky, and the other to deal with Severus. Those spells were easily blocked by him.

He moved forward calmly, while the Aurors fled in embarrassment because they did not dare to face the Obscurial. At the same time, Severus raised his wand and waved it in a circle, and a ball of blue flame was like an outstretched wing.

It flew out like a giant bird.

This was such a mess, but someone shouted "Grindelwald", and Severus couldn't help but laugh even more happily.

Grindelwald's blue flame and black magic are amazingly powerful, however, these Aurors really misunderstood.

He really has no interest in ruling the world, only a madman would think that.
