Vulcanized rubber, this American Charles. Goodyear's genius invention in 1839 was later called one of the four major industrial raw materials, along with steel, oil, and coal.

Since it can be said to be on a par with steel and oil, there is no need to say how important it is.

In this era, although rubber was discovered and used as early as the seventeenth century, due to the oversensitivity of natural rubber to temperature, it will become soft and sticky when the temperature is slightly higher, and it will have a foul smell, and it will become brittle and hard when the temperature is low.

This disadvantage makes rubber derivative products of no commercial value except for being used as erasers!

How much money can an eraser sell for? So right now, rubber isn't a welcome discovery.

In fact, even Charles who invented vulcanized rubber. Goodyear, he did not get much benefit from this invention, but instead caused him to be in debt, and suffered from various diseases due to long-term heating and melting of natural rubber.

The only benefit that this American 'good day' gentleman gained from vulcanized rubber was that his name was used on tires, which became famous as Goodyear tires.

But Charles. Goodyear didn't get much benefit from vulcanized rubber, not because vulcanized rubber didn't work much, but because it was not difficult, it was very easy to be imitated, and it didn't need any big business, a family workshop could do it.

After inventing vulcanized rubber and obtaining a patent, Goodyear spent a lot of time and money fighting lawsuits for his patents for eleven years after that.

Another important reason is that Charles. When Goodyear invented vulcanized rubber, he didn't know how to make the most of this new thing, and he wasn't sure what he could do with vulcanized rubber.

Eventually, the guy used vulcanized rubber to make combs, buttons, and even carpets.

emmmm, these things can make a dime a dime! Besides, vulcanized rubber carpets,, hell how much can be sold!

Its real use should be to make waterproof and insulating gloves, shoes, various rubber tubes, or condoms, and most importantly, carriage wheels.

Hell, how many sales can be sold of buttons, combs, and carpets, the sum of the three is estimated to be less than that of condoms.

London, Carlton House, Ye Kai looked at George IV with interest, this fat man was slumping on a long chair, even if he heard the waiter inform Ye Kai that he had come in, the later British King His Majesty only got up symbolically to greet him, and then collapsed down, which is very rude in the European royal family that pays attention to etiquette.

However, Ye Kai not only understood him, but also gave him a sympathetic look, because after this fat man came back from Portsmouth with Ye Kai, he was completely knocked down!

However, it was not the Assassin or the disease that struck him down, but the fact that His Royal Highness the Prince of Wales was struck down by a huge debt.

In other words, this guy already owes an unimaginable amount to ordinary people, and the little nobleman will directly choose to commit suicide when he hears it, and after his father Qiao San knows about it, he may kill him with one shot of the huge debt, which is as high as 150,000 pounds!

Of course, this is not much at the moment, and in 1795 he married his cousin Caroline. Amelia. When Elizabeth got married, he owed a staggering debt of £600,000.

Speaking of spending money, to be honest, Ye Kai has seen a lot of second ancestors who spend money on the Internet in his later generations, but no one can compare with Qiao Si in front of him!

You must know that the current middle-class family only has an income of about 120 pounds a year, that is to say, the current debt of this guy is equivalent to the external debt of 1,200 middle-class income for a year.

If you put it in the republic of later generations, a middle-level person who works in the richest company and above enjoys a wonderful 996 blessings, and his annual salary is about 70 to 100 a year.

Even if we calculate 85 compromises, 1,200 and 850,000, and erase the fraction by exactly 100 million, and then consider the global economic situation in the 18th century, I am afraid that we will have to multiply it by two.

And this is when he was given £500,000 in 1783 to renovate his palace, and he was also given an annuity of £60,000 a year, and his father, King George III, would give him £50,000 a year.

That is to say, in three years, George IV received an appropriation of 500,000 pounds + an annuity of 330,000 pounds from Parliament and the king, and then a foreign debt of 150,000 pounds, a total of 980,000 pounds!

And this money is gone in just three years, with an average of almost 330,000 pounds a year, which is equivalent to almost 500 million yuan in later generations, that is, an average of 1.37 million yuan a day!

Served! It's really a thunderous and explosive means of spending money, this is still an era when there are no yachts, private jets, and no luxuries, this spending speed, I'm afraid that the urban gods in the starting point don't dare to write, because it's too unreasonable!

So Ye Kai forgave Qiao Si's gaffe and sympathized with him, because he would soon be forced to move out of the Carlton Mansion because he couldn't pay off his debts, and he lived in Maria aggrieved. Fitzherbert went to his apartment on Mayfair Park Street, the first Prince of Wales in British history to lose even his own palace.

"Frederick! That's rude, don't do that! Your Excellency, Marquis, I'm really sorry, His Royal Highness the Prince is a little uncomfortable. ”

The only one who can generously call George IV Frederick is Maria. Fitzherbert, he gently nudged Qiao Si and looked at Ye Kai apologetically.

Ye Kai also looked at this woman who had been married twice and was already thirty years old, but she could still fascinate the Crown Prince of England.

However, after quietly and carefully looking at it for a moment or two, he couldn't help but doubt Qiao Si's taste and vision.

The citizens of London were right, this Mrs. Fitzherbert can only say that it is not difficult to see that at least it is not difficult to see that it is not pretty, round, as long as a cabbage, and there are a little freckles on her face!

"It's okay madam, I'm the same as His Royal Highness the Prince, just like friends, don't care about these etiquette or anything!"

Ye Kai shook his head and smiled and put gold on his face, at best, he and Qiao Si could only talk to each other, what was the same at first sight, there was nothing at all.

"Yes! Mary, I am good friends with Mr. Ye, don't worry about this, Ye, since you are here, accompany me to have a good drink here, maybe I won't be able to live here at any time!

By the way, Miss Jenna said that your fried steak is also very rare and delicious, why don't you let me and Maria try your craftsmanship today! ”

Hearing Ye Kai claim to be his good friend, Qiao Si finally became a little interested, he shook it twice before he got up, he still looked familiar, no matter what he wanted, he just opened his mouth and said.

"No problem, then I'll cook it myself today, Prince, I also sent you and Mrs. Fitzherbert's dresses!"

I don't know why, Qiao Si never called Ye Kai's French name Zinedin, but called him Ye directly.
