Because the Queen was unhappy with Downing's atheistic attitude, Prince Albert's enthusiastic Royal Photographic Society project was also ruined. Regardless of this result, the Leica camera was officially released on November 11 as promised.

In this era of the suffering of the working class, the prosperity of heavy industry was what Downing pursued, but since it was invented at the time of improving the printing press, it should be produced well.

The Leica camera was a luxury item to rent for £100 a year, but its delicate, beautiful elf-like shape and full-color ability to capture moving images instantly conquered the hearts of European aristocrats and became the most sought-after luxury. The French people who love luxury are crazy, Louis? Napoleon couldn't stop it, he wanted to ban the sale of this gold-absorbing machine from the hands of the republican financier Downing, but his friends constantly persuaded him: "Forget it, this is a fun little thing, you can't make much money...... often repeatedly, Louis had to give up the ban, so that the little thing has a chance to sweep the French market. Perhaps it won't be long before the dictator, who hates Downing, himself lets the photographer click a Leica on it......

And what makes him hate it even more...... Eugénie, one of his fiancée candidates, left Paris for London with her mother, Madame Montiro. Because at this time Downing was openly recruiting sales agents for Leica throughout France, Madame Montiro, the daughter of a liquor wholesaler, had some business acumen, saw the business opportunity of Leica cameras, and thought that all the French aristocracy should be fascinated by it. And her daughter, Countess Eugenie, praised "handsome" because of a photo taken by Prince Albert of Downing. In that snapshot of the Prince, Downing laughs and reveals the neat white teeth that are extremely rare in this era, as brilliant as the sun god Apollo, shining on the heart of a young girl like Countess Eugenie.

Prince Albert is a super handsome young man, Queen Victoria took the initiative to propose to her cousin, and this genius inventor Mr. Baron Buckingham is actually more handsome than Prince Albert, laughing and unmarried! The insidious Madame Montijo took her daughter to London to meet the world, and met the most handsome and richest little baron in the world, and gave it to Louis by the way? Napoleon pressed.

Eugénie is a super punctual Spanish beauty, the favorite woman in the heart of the dictator Louis, but he wants to marry a princess before he ascends the throne, so he has been hesitant not to propose to the Spanish countess of Teva.

Downing is now a small part of the literary circle, and often sponsors some literary and artistic activities, in the French-speaking literary world, he has Hugo and Alexandre Dumas as his companions, and in the English-speaking literary world, he has the editor-in-chief of the daily news Forster, and Foster's friend Dickens has left England for the continent with his family, and has never met him.

Serra, the wife of a merchant of the East India Company? Prinsep liked to hold regular salons in her little Dutch house, where writers, artists, and celebrities would gather, and by virtue of her husband's connections, he had invited Downing, a shareholder of the East India Company, to whom he met Madame Montiro.

Mrs. Princesp was born in a famous family of beauties, the Patel family, although she is no longer young, but she still has charm and coquettishness, and is deeply loved by people in the literary and artistic circles. Of course, her beauty pales in comparison to that of the 26-year-old Eugenie, the Countess of Teva. Although Tang Ning is pretentious, he has never hunted for beauty since he came to this world, and he is focused on construction, but it also depends on who the other party is, and he is also dumbfounded when he is like Countess Tewa.

The countess has a well-proportioned figure, a graceful body, and a very plump chest under her broad shoulders, and her sexy appearance in a low-cut dress can turn a gentleman into a gladiator in an instant. The golden, reddish-brown hair was radiant, and the delicate and fair skin was dizzying, and the blue-gray eyes of the beautiful woman also looked at the Buckingham Baron. The baron's handsomeness really did not disappoint her, although he was only a very low-level baron, but he lived in the manor of the Duke of Buckingham, not to mention his status as the telegraph king, the steel king, the bicycle king, the camera king and other four heavenly kings, no one is more tyrantous than this little baron. Moreover, the era of aristocratic supremacy has now passed, and the European Revolution of 1848 even made the word "aristocracy" synonymous with danger, with civilians often attacking innocent nobles. The capitalists are the big winners who represent the future.

The 26-year-old Eugenie is not as shy and young as a teenage girl, she is down-to-earth and generous, and takes the initiative to meet the local tyrants, which makes Tang Ning feel very honored. Eugenie's mother, who is half Scottish, and her father, a former diplomat in the United States, were educated in Paris, but she also excelled in English, and they had no language barrier. Eugénie was born in Grenada, Spain, but the French conquered the Spanish Empire, and Eugenie's father fought for Napoleon and was blind in one eye. It was normal for the children of the Spanish aristocracy to go to Paris to be educated.

The big tyrant really doesn't know much about literature, and here in the literary salon, he listens more and talks less, and lives up to the name of the tyrant. And Eugenie is obviously much better than him, a literary beauty, talking and laughing with the writers present, she is really a celebrity in the world, it is estimated that there is no man present who is not fascinated by her. On the contrary, the local tyrant looked a little rustic, sitting quietly in the corner and admiring the beauty.

Then it's the season for artists to shine. Spain is the homeland of the guitar, and a musician who has traveled to Spain for many years plays and sings by himself, which is very good, arouses the homesickness of the countess, and talks with the musician about many topics with Spain.

The local tyrant, who has always been calm, has a faint sense of jealousy, which is really a rare feeling.

In addition to his obsession with his ex-girlfriend, Downing also has an important reason why he does not dare to find a lover lightly, this is an era when there is no contraceptive industry, either you try to find a suitable person to marry, like the queen and couple, and have children all the time, or, you are like Alexandre Dumas, be a big stallion, and be a big bad guy who is not in charge. I don't know if it's because he was caught in the door when he traveled through the door of time and space, at this time, Tang Ning suddenly remembered that the contraceptive industry was coming, and he not only wanted to, but also had the ability to create the industry.

If the world hadn't been changed by Downing, the world's first rubber condom would have been made by the French in 1855, and this thing is very crude, about the same as the inner tube of a bicycle, what would it be like to be the first couple to enjoy this kind of gadget......

Although Downing had little say in literature and art, he was the most prominent local tycoon in the room, so Madame Princesup, who presided over the salon, asked him to speak after most of the program was over.

The big tyrant is also very gentlemanly and humble, and after expressing that he is a "rough man" who only knows how to make small inventions, and has nothing to say about literature and art, the big beautiful countess asked him to introduce some good things that he is developing.

Hey? This is a good idea, everyone knows that this great inventor is infinitely creative, and it is really a very good conversation point to know in advance what he wants to invent.

Downing's mind is full of condoms now...... Do you think he didn't dare to say it? It's just that...... He would not say it explicitly, lest the gentlemen and ladies present should flip the table. After thinking about it, he said: "Before talking about inventions, I will talk about a few phenomena in the animal world, which are very peculiar phenomena and a little scary, ladies have no opinion, right?" ”

Horror stories? Interestingly, the ladies have said that it is okay.

Downing began to tell the story: "There is a bird called the cuckoo. Naturalists were curious about the habits of cuckoos, as they found that cuckoos neither nest nor hatch eggs, nor raise offspring. So, how did they pass on their lineage? After observation, the scientists discovered the secret of the cuckoo - it turned out that they secretly laid their eggs in the nests of other birds, and those birds who did not know the truth became the godfather and godmother of the little cuckoo.

How can a cuckoo parasitize its eggs in other nests without the conspiracy being discovered?

At the turn of spring and summer, before the female cuckoo lays eggs, she will carefully search for the nests of small birds such as thrushes and reed warblers, and after selecting a target, she will take advantage of the similarity of shape, size and body color to the harrier and fly from afar. They also fly like raptors, rock harriers; Fly very low, one moment to the left, the next to the right with sharp turns. Occasionally, they flapped their wings and flapped them loudly to intimidate the birds that were incubating their eggs. When the little bird that is incubating its eggs sees the figure of a bird of prey soaring at a low altitude and is so frightened that it abandons its home and flees for its life, the cuckoo achieves its purpose of intimidation.

How does a cuckoo throw its eggs into someone else's nest? Some lay eggs directly, while in nests that are too small or difficult to get into, it lays eggs first, and then carefully places the eggs between the eggs with its beak. But before putting their own eggs, cuckoos often take one of someone else's eggs from their nest and eat or throw it away!

The cuckoo is much larger than some small birds, but the eggs it lays are very small, and the cuckoo eggs are strikingly similar to the eggs of the nest owner in terms of shape, color, etc., so it can be mixed with other small birds, and it is difficult to distinguish the real from the fake.

Although small, cuckoo eggs develop quickly and tend to hatch earlier or at the same time than the eggs of the nest owner.

Bad parents have even worse children!

As soon as the baby cuckoo is born, it is busy working as a porter: carrying another small bird or egg, supporting it with its undeveloped wings, and carefully crawling towards the edge of the nest. It lowered its head, put its forehead against the bottom of the nest, and suddenly leaned back sharply, and lifted the little chick or egg that was lying on its 'shoulder' upwards and turned it out of the nest! Belch...... Yes, just fell to death! The little villain then slipped to the bottom of the nest and burrowed under another victim to continue its work. A few hours after the baby cuckoo hatches, it has the tendency to drop everything in the nest. When the stepmother came back and saw that there was only one chick left in the nest, she couldn't help but cry, but there was no way, the mother bird who was kept in the dark would love the murderer as a darling and nurse the little cuckoo more carefully. When the little cuckoo was plump, it said goodbye and flew away. ”

The cuckoo turned out to be such an evil being! The ladies were all indignant and denounced this kind of big badass.

But...... What does this have to do with Downing's invention? Instead of solving the mystery right now, he continued to tell the story: "Do you think the little cuckoo is bad? No, there are even worse. A kind of swallow that lives in the United Kingdom, after the birth of a cute little swallow, it will even drop the eggs of its own siblings outside the nest! The little cuckoo murdered the child of his righteous parents, but after all, it was not his own siblings, and this little swallow was even more murderous. Why would Little Swallow do this? The reason is very simple, because there is not enough food, and one more egg is broken, and the little swallow has more chances of survival. ”

The story is really a bit cruel, but everyone still doesn't understand what this story that doesn't know whether it's true or false is trying to prompt.

Downing continued the cruel story: "If you think that this kind of thing is cute, I'll talk about the bad things about animals when they grow up." The island of Dominica in the Caribbean is widely home to a species of spider that has a terrifying name: Black Widow. Because it is poisonous, biting people can even be fatal. One of the most terrifying habits of black widows is that if the female spider feels hungry after mating, she will decisively eat the male! Because the spider is a passive predatory insect, it does not know when it will have its next meal, and its own small size does not store much energy, such a habit can improve the nutrition of the spider in a certain way.

Either way, it's for the next generation, and motherly love is always great. But...... The next one I'm going to hack is my mother. As we all know, because the direct point of the sun will move between the northern and southern hemispheres, half a year in the southern hemisphere, half a year in the northern hemisphere, such a natural law to the earth's Antarctic circle and the Arctic circle has brought a peculiar polar night and polar day phenomenon, the polar night is a continuous half a year is a dark night, no sunlight irradiation, the polar day is a continuous half a year is daytime, the sun will always hang in the sky.

In such a harsh environment, there is a mammal called the polar bear, which lives in the Arctic Circle and can be found in Canada, Alaska in the United States and Siberia in Russia. Polar bears have thick fur and thick fat, during the polar day, polar bears go all out to find food in the desolate and cold Arctic Circle, they mainly eat seals, but in that harsh environment, they can not be picky eaters, but they can catch fish, shellfish, crabs, young whales, they eat all, in late summer they can also eat paddle fruit and tree roots. All food is eaten to store energy in the body, and this is true for male bears, and even more so for pregnant female bears. This is to cope with the polar night without food.

Before the polar night, the mother bear will dig a hole in the snow, and after the long winter, when the sun appears again, the baby bear has been born, very cute and lively. Generally speaking, a mother bear will give birth to a pair of baby bears, sometimes three or four. By the time the baby bear is able to walk, the mother bear's fat has almost all been converted into milk, and she must rush to the melted ice cubes to find food before her body runs out.

The mother's hunger is getting stronger and stronger, and she walks faster and faster, and the baby bear can barely catch up with her mother. Naturalists observed that the mother bear was really fast, as if to test the baby bear's ability to run. And when a baby bear is too poor to meet the standards of a mother bear, what do you think the mother bear will do? Is it to slow down and wait for all the baby bears to catch up? No! Mama Bear will decisively abandon her baby bear. Very, very cute baby bear, likely abandoned because of their slow steps. （http:／／）。 Why? Again, the word: scarcity. Only strong, healthy babies are qualified to grow and grow. This is the law of nature.

Don't think that only the animal kingdom has scarcity. Of course, there are among humans. Mrs. Gaskell's Mary? Barton's book describes the scarcity and forties of England, where the children of unemployed workers endured terrible famine, and their big eyes, which should have been bright, now looked confused, as if crying out in pain: Why did you give birth to us? Why bring us to this world of pain and despair?

Britain is the most powerful country in the world, and its citizens were still under the threat of famine not so long ago. How many hungry children are there on this planet? What's more, we human beings should not only have food, but also the right to education, the right to enjoy life, the right to enjoy sports, the right to travel, and the pursuit of freedom and wealth, which is where the dignity of all people lies. But now many people do not have such dignity, and many parents have to raise their children without enough to eat, more and more children. This is not fair, this is not free, this is not scientific, this is unreasonable, the next thing I want to invent is to give all parents the ability to control the time when they have children! Have the ability to decide how many children to have according to your own situation, so that each child is guaranteed to have food, go to school, find a spouse, have dignity and freedom! ”

Everyone was moved by the speech of the great good man, and the effect was good, if Tang Ning directly said that I wanted to invent the "condom", it would definitely be sprayed to death, and now, the gentlemen and ladies are infected by his "great sentiments", and some people ask "what exactly do you want to invent?" ”

Tang Ning smiled but did not answer: "You will know when the time comes." ”
