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

What surprised Qin Di was that he really bought salicylic acid, acetic anhydride and citric acid!

Since the beginning of the 19th century, European technology has flourished and there have been various chemical companies.

Zhu Wan didn't buy much, and each item only bought a large bucket, 31 gallons per barrel, 118 liters, plus the shipping fee, it cost a total of 1,800 oceans.

A silver dollar in this year can be exchanged for about 0.6 US dollars. If you buy a boat ticket from London to the Magic City, it only costs 80 US dollars, which is 130 oceans.

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

The main force in the experiment was naturally Zhu Wan. Qin Di could only watch from the side because he was too young.

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

Zhu Wan looked at the pills and half-believed them: "A Di, it was created so easily? Is this aspirin? Can it be taken? Will it die?"

Qin Di said: "First take a few pieces to feed the pigs to see if they will die. Then find patients with high fever to try whether it works. Don't worry, I'm 99% sure, this is aspirin."

Drug testing is a very rigorous science, but at this time, the Magic City was neither the Drug Administration nor the Drug Administration, so it was naturally not so rigorous. There are many poor people with fever, all over, vaguely, and they are about to die. Not to mention feeding a few pills, even arsenic can be fed a few dollars.

Zhu Wan first used rabbits, pigs, and dogs for experiments, and then took the courage to reduce the dose to the patient in half. The result was that the effect was as good as the gods. The high fever quickly subsided, and the effect of antipyretic and analgesic was excellent. Except for a few people with stomach discomfort, there were no major side effects.

Therefore, after testing thirty patients, Zhu Wan seemed very excited: "A Di, it's done! This is aspirin!"

Qin Di smiled and said, "Mom, we have to change its name, it's better not to use 'aspirin'."

"Why?"

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

"What do you think is good?"

Qin Di thought for a while and said, "It might as well be called 'Tianliang Pills'. Traditional Chinese medicine treats high fever, and there is a way to clear the coolness of the sky."

Afterwards, Zhu Wan accepted Qin Di's suggestion and began to raise funds and order more raw materials. In a remote place in Chongming Island, she bought a hundred acres of barren beach and built a courtyard house. There was a high courtyard wall outside and there were more than a dozen houses inside. She quietly opened a pharmaceutical factory.

The pharmaceutical factory is very small in size, 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 pharmaceutical store in the Concession of the Magic City, recruited two salesmen, responsible for selling drugs to major pharmacies.

All this was done quietly. Pharmaceuticals don’t know what the white powder is for; pharmaceuticals sellers don’t know where the “Tianliang Pie” comes from, and they think it’s imported medicine.

Soon after, money began to make money like flowing water.

In less than two years, I made more than 100,000 yuan in sales around the Magic City alone.

Next, Qin Di persuaded his mother to open an account at Chase Bank and exchange silver dollars for US dollars and pounds as much as possible. Because overall, these two are the strongest currencies in the 20th century, and silver is unreliable.

From 1870 to 1935, silver collapsed and fell against the US dollar.

In 1870, a piece of ocean could be exchanged for US$1.43. In 1890, a piece of ocean could be exchanged for US$1.05. In 1908, a piece of silver could be exchanged for US$0.6. By 1930, it could be exchanged for US$0.3. In 1932, a piece of silver dollar could be exchanged for US$0.22.

Because China is the silver standard, the depreciation of silver dominated by the West plundered the wealth of the Chinese people, accelerated the collapse of the economy, and made the lives of the people even more difficult.

In the autumn of 1909, Qin Dijiu was one year old.

At this time, Zhu Wan saved up 100,000 US dollars and was already a rich woman hidden in the Demon City.

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

Since aspirin was made, money has flowed in. As a doctor, Zhu Wan not only learned more about the magical medicine for heat and pain relief, but also accumulated a fortune. So she was almost obedient to her son, and this time she did not hesitate to believe what he said.

The mother and son came to the Huashang Exchange and bought the stocks of three rubber companies through brokers, namely perak, kalumpong, and senawang. Each of them bought 20,000 US dollars, equivalent to 33,000 oceans.

Most of the stocks traded by the Magic City are foreign companies. The stocks of this year are not later electronic files, but original paper stocks with the words "How much does one stock equal to silver dollars" and some colorful seals.

After buying it, the two of them returned home and put the stock in the safe, leaving them alone.

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

Previously, Zhu Wan told him about opening a pharmaceutical factory, but he didn't take it seriously.

Because most of the funds were Zhu Wan's private money, half of the funds were borrowed from Zhu Mingcheng, the Qin family did not invest money, and Qin Hancheng had never looked at the company's accounts. Therefore, when he saw these stocks, he first felt that his wife was crazy.

Zhu Wan smiled slightly and said, "I didn't borrow money. This is what I have made in the past two years. Even if I lose, I'm not afraid."

She was right, because the profits of pharmaceutical factories are rising steadily and with the continuous sales of Tianliang Pharmaceuticals, it has recently earned 20,000 oceans every month, so she has the confidence to dare to buy stocks.

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

In the early 20th century, with the rise of the automobile industry, the demand for rubber gradually increased. In 1908, the United States imported US$57 million, and in 1909 it increased to US$70 million. The price of rubber continued to rise, driving the rapid increase in stock prices, and many people began to pursue rubber stocks.

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

So, Qin Hancheng couldn't sit still, jumping up and down every day, his heart as if there was grass growing in his heart. Whether it was okay, he began to mention rubber in front of his father and brother.

"Dad, I tell you that my family bought some rubber stocks, and it has tripled!"

"Brother, rubber has risen, it has risen again, haha, it rises every day, it makes people feel itchy..."

At the same time, businessmen outside are also rumoring that buying rubber can make you rich, and whoever makes a fortune will make you rich.

Lies can't help but repeat them every day, and repeated them many times are like true.
