In the blink of an eye, more than half a year has passed.

To Qin Di's surprise, salicylic acid, acetic anhydride and citric acid were really bought!

Since the beginning of the nineteenth century, science and technology have flourished in Europe, and there have been various chemical companies.

Zhu Wan didn't buy much, she only bought a large barrel of each, a barrel of 31 gallons, 118 liters, plus the freight, a total of 1,800 oceans.

A silver dollar of this year can be exchanged for about $0.6. And buying a ticket from London to the magic capital is only 80 US dollars, which is 130 oceans.

Subsequently, the mother and son found a room in Ci'an Hall and began to try medicine.

The main force doing the experiment is naturally Zhu Wan. Qin Di was too young to watch.

After some effort, two months later, the first batch of white powder was made, about five kilograms, plus a small amount of starch, to make more than 10,000 small tablets of 325 mg each, which was also the standard dose later.

Zhu Wan looked at the pill and was skeptical: "Ah Di, it was made so easily? Is this an aspirin? Can you eat it? Will it be dead?"

Qin Di said: "Take a few pieces and feed them to the pig first, and see if they will die." Then find a patient with a high fever to see if it works. Don't worry, I'm 90% sure that this is aspirin. ”

Drug testing is a very rigorous science, but at this time, there is neither the Food and Drug Administration nor the FDA, so it will naturally not be so rigorous. There are a lot of poor people with a fever, who are hot, confused, and about to die, let alone feed a few pills, even arsenic can be fed for a few dollars.

Zhu Wan first experimented with rabbits, pigs, and dogs, and then took the courage to reduce the amount by half to the patient, and the result was like a god, the high fever quickly subsided, and the antipyretic and analgesic effect was excellent, except for a few people with stomach discomfort, there were no big side effects.

Therefore, after Zhu Wan tested thirty patients, she seemed very excited: "Adi, it's done! This is aspirin!"

Qin Di smiled: "Mom, we have to change its name, it's best not to use 'aspirin'." ”

"Why?"

"Because we haven't applied for a patent yet, changing the name can reduce the hassle. ”

"What's your name?"

Qin Di thought for a while and said, "You might as well call it 'Tianliang Piece'." Traditional Chinese medicine treats high fever, and there is a way to cool the sky. ”

Subsequently, Zhu Wan accepted Qin Di's suggestion, began to raise funds, ordered more raw materials, and bought a hundred acres of barren beach in a remote place on Chongming Island, built a courtyard house, with a high courtyard wall outside, and more than a dozen houses inside, and quietly opened a pharmaceutical factory.

The size of the pharmaceutical factory is small, with only three employees in total, because the raw materials are imported, the pharmaceutical process is relatively simple and does not require too many people.

In addition, she also opened a medicine store in the Modu Concession and hired two salesmen to sell drugs to major pharmacies.

All this was done quietly, and the pharmaceutical people didn't know what the white powder was for, and the people who sold the medicine didn't know where the "Tianliang Tablets" came from, and they thought it was an imported medicine.

It wasn't long before the money started coming in like a running stream.

In less than two years, just selling around the magic capital has earned more than 100,000 oceans.

Next, Qin Di persuaded her mother to open an account with Chase Bank and exchange silver dollars for dollars and pounds as much as possible. Because on the whole, these two were the strongest currencies of the twentieth century, and silver was unreliable.

From 1870 until 1935, silver had a big crash, falling all the way to the dollar.

In 1870, a piece of ocean was worth $1.43. In 1890 it was worth $1.05. In 1908 it could be exchanged for $0.6. By 1930, it could only be exchanged for $0.3. In 1932, it reached its lowest point, when a silver dollar could only be exchanged for $0.22.

Because China is the silver standard, the Western-led depreciation of silver has plundered the wealth of the Chinese, accelerated the collapse of the economy, and made the life of the common people more difficult.

In the autumn of 1909, Qin Di turned nine years old.

At this time, Zhu Wan had saved 100,000 US dollars, and she was already a rich woman hidden in the magic capital.

In early October, Qin Di asked his mother to take out $60,000 to buy rubber stocks.

Since aspirin was made, silver money has been flowing in, Zhu Wan, as a doctor, not only knows more about the miracle medicine of heat and analgesia, but also has accumulated a windfall, so she is almost obedient to her son, and this time she did not hesitate to believe what he said.

The mother and son came to the China Commercial Exchange and bought the shares of three rubber companies, namely Perak, Kalumpong, and Senawang, through brokers. Buy 20,000 U.S. dollars each, which is equivalent to 33,000 oceans.

Most of the stocks traded in the magic capital are foreign companies, and the stocks of this year and month are not later electronic files, but original paper stocks, with the words "how much is a share equivalent to silver dollars", and there are some colorful seals.

After buying it, the two went home, put the stock in the safe, and left it alone.

About a month later, my father, Qin Hancheng, accidentally opened the safe and saw the stocks pressed at the bottom of the box, and couldn't help but be surprised: "Awan, when did you buy the stocks? Why did you buy so much? Do we have so much money? Oh my God, where did you borrow the money? You are too bold! What can you do if you lose money?"

Previously, Zhu Wan told him about starting a pharmaceutical factory, but he didn't take it to heart.

Because most of the funds are Zhu Wan's private money, and a small half of the funds are borrowed from Zhu Mingcheng, the Qin family did not invest funds, and Qin Hancheng did not read the company's accounts. So when he saw these stocks, he first thought that his wife was crazy.

Zhu Wan smiled slightly and said, "I didn't borrow money." This is what I have earned in the past two years, and I am not afraid even if I lose it. ”

What she said is not wrong, because the profits of pharmaceutical factories are rising, and with the continuous hot sales of Tianliang tablets, recently, there have been 20,000 oceans of income every month, so she has the bottom in her heart before she dares to buy stocks.

Qin Hancheng only felt frightened, from this day on, he began to care about the price of rubber.

At the beginning of the 20th century, with the rise of the automobile industry, the demand for rubber gradually increased, and in 1908, the United States imported 57 million US dollars of rubber, and in 1909 it increased to 70 million US dollars. The rising price of rubber has led to a rapid increase in stock prices, and many people have begun to chase rubber stocks.

Three months have passed in the blink of an eye, and the stock of $60,000 has tripled, and it is already $180,000!

So, Qin Hancheng couldn't sit still, jumping up and down every day, like grass growing in his heart. Nothing happened, and he began to mention rubber in front of his father and brother.

"Dad, let me tell you, my family bought some rubber stocks, and they have tripled!"

"Big brother, the rubber has risen, and it has risen again, haha, it has risen every day, and it has made people's hearts tickle......"

At the same time, outside businessmen are also spreading every day, saying that buying rubber can make a fortune, and whoever has made a fortune.

The lie can't help but be repeated every day, repeated many times as if it were true.
