No matter how many industrial and mining sites there are in Taiwan, there is also a time to finish reading.

One day in Zuihou, Taiwan, Sun Defa walked into a bookstore in Taipei, which was recommended to him by the tour guide Xiaomei. According to her, his uncle likes to study Taiwanese history and also runs a bookstore with a lot of information about Taiwan.

Along the way, the two talked about it. The little sister prepares her various materials well, Sun Defa is serious about being a curious uncle, and the background of the same Hakka makes it easier for them to get along. Inadvertently, Sun Defa knows a lot about the current situation in Taiwan.

Many of Taiwan's information books on the Ming and Zheng periods are mostly published privately and are reluctant to be posted on the Internet, and are generally distributed from bookstores. Her uncle's bookstore was one such one.

When Xiaomei walked into the bookstore with Sun Defa, he immediately liked the atmosphere here.

The bookstore is not large, and there are not many types of books, neatly arranged on the shelves on the walls. There is also a long table under the bookshelf with antique chairs for guests to preview. Some of the corners are lined with tall stands with blooming orchids, and the delicate scent of orchids matches the name of the Orchid Bookstore. There is also a tea table in the store, which looks like it has been around for many years.

At this time, Sun Defa was sitting at the tea table waiting for the owner to serve tea. The shopkeeper is no less skilled than him in playing kung fu tea. After the tour guide Xiaomei introduced Sun Defa to her uncle, she left, and said with a smile, she is tired of watching you drink kung fu tea.

The two of them drank tea and chatted for a while, and then they had nothing to say.

The owner's name is Lin Weisheng, and he loves to study history, especially Taiwanese history.

Sun Defa seemed to inadvertently ask, "What does Mr. Lin think of Mr. Shi Ming's "Four Hundred Years of Taiwanese"? ”

Lin Weisheng smiled: "There are too many fallacies. If the study of history is mixed with ideological elements, it will be doomed. ”

"What do you think is wrong?"

"Two simple examples. As he said in the book, there was no definite record of agricultural migration from the mainland to Taiwan before the Netherlands. However, from the photocopied genealogies of the 28 Taiwanese families I have collected, there are hundreds of evidence that mainlanders took the initiative to migrate to Taiwan in the past, and the earliest was from the Southern Song Dynasty. Also, when he cites the material from the Diary of Resharan and the Diary of Batavia, he ignores the distinction between Old Dutch and Modern Dutch, and makes the grammar of the latter and the previous two grammars wrong, haha. ”

"Then you must be very famous in Taiwan's historical circles."

"Where, where, I don't want to get involved in such historical research, and I don't bother to argue with him."

"Hehe, folk master."

"People in their forties, what a name, profit, I don't want to fight. It's better to do something you love than anything else. ”

"Yes, but I have a suggestion that you're definitely interested in." Sun Defa smiled mysteriously, "I'm going to conduct a survey in the Philippines for the original inhabitants—"

Afterwards, Sun Defa explained to everyone: "After walking down the big circle of Taiwan, I found that I only understood the surface, and I did not know enough about the internal customs and ethnic minority issues. There is a real need for such a researcher of local history who does not care much about fame and fortune. ”

Sun Defa returned to the company from Taiwan, and before he got rid of the exhaustion, he was going to meet someone.

An unsightly man is waiting for him in the office, the small boss of an underground bank. This is all about him in advance.

The little boss greeted Sun Defa with a smile: "Brother Fa, our first brother asked me to talk to you." The first brother said that more than 10 million is nothing to you, but our company has big rules, so we still have to talk about it. ”

"Of course, Ah Fu is a cautious person."

"In this society, anyone who is not cautious will be on the street at any time."

Mr. Sun contacted a finance company last month. It is based in Hong Kong and is responsible for all kinds of money laundering and short-term loans. In Sun Defa's circle of friends, some people borrowed money from them and used it urgently, and the interest rate was not too high. Sun Defa had long planned to mortgage all the rental houses and exchange them for cash.

He has no nostalgia for this shijie.

His elder brother was a selfish peasant who had moved to the city in the new era, and the family couldn't talk to Sun Defa. Other relatives only come to him when they borrow money or ask him to spend it. To be honest, on the surface, he is calm, but in fact, in his heart, he values friendship more than anyone else.

The two of them talked softly while drinking, and those who didn't know thought they were old friends for many years. Soon, a fifteen million mortgage was almost finalized.

Over the next six months, they gave him the loan in three tranches. When Zuihou took out a loan to Sun Defa, Sun Defa gave up all his rental houses and they took over. A year later, Sun Defa repaid the loan in three instalments, each with 20 percent interest.

The little boss left happily, he did a very successful deal, and it was certain that he would be praised by the first brother, and there must be a bonus.

Sun Defa estimated the time and waited for the delivery of the oil and gas extraction and processing equipment he had ordered, just in time to use the first loan. This money can't be carried in other equipment, and it's not easy to get it from Wu Dapeng. It's easy to be noticed by those who care. The more critical the period, the more careful you must be.

However, he didn't seem to notice, if he didn't come back, what would happen to those small property rental houses? Can those people on the road go through the relevant procedures?

Sun Defa was busy and drove to a certain street in Longhua Town, where he had a laboratory. It used to be a mailroom in a warehouse, but the warehouse moved out and became empty. The location is not very good, and it has not been rented out. When he was looking for a more remote bungalow, a friend happened to know about the place. Sun Defa easily rented it and made some changes.

Smokeless gunpowder, also known as nitrocellulose, can be bought online, and if you have the heart, there will be a thousand ways to avoid all kinds of controls. However, when the five of them discussed, they still thought that it must be developed by themselves. Of course, it was not to doubt Sun Defa's ability, but just in case.

Sun Defa didn't care that his friends were suspicious of questioning his abilities, he still had his own jihua, and he wanted to take a look at a patent application he found on the Internet by the way.

In 1991, a gentleman applied to the Patent Office for a patent for a method of making smokeless gunpowder from dragon's whiskers, but the process was understandably unknown. Judging by the description, there is a good chance that it will work. Sun Defa wanted to try it out first, and if it worked, he would buy the patent.

The production process of chemical products is slightly different, and the products are very different. So the complete jishu description and process flow are very important. Besides, Li Ziqiang's urging was tight, and Sun Defa felt that he couldn't delay it any longer.

The dried dragon beard grass he asked Li Ziqiang to prepare had been delivered by courier. The trunk of Sun Defa's car also contained the absorbent cotton he bought and the No. 1 strong cotton he got from a special channel. Absorbent cotton is medicinal cotton, a big bag of five yuan; No. 1 strong cotton refers to cotton with a nitrogen content greater than or equal to 13.13%, and it is also degreased. This isn't something you can buy in a hospital.

Where did he get it from? Sun Defa didn't say anything about beating him to death, and he didn't do anything about betraying his friends.

After renting this house, he successively added some chemical experiment equipment and supplies, mainly to prepare for the production of nitrocellulose in the laboratory.

Conventional propellants are made of nitrocellulose mixed with volatile solvents or explosive solvents. This is common sense, and it has been the case for nearly a hundred years, and even at this moment, the guns and artillery propellants of the United States and European powers, if there are no special requirements, more than 80% of the propellants are it. Therefore, Sun Defa didn't want to get a new type of propellant. It's just that we want to find some way to replace some modern components of modern propellants that are difficult or simply cannot be solved in a short period of time. After all, when I got there, I don't know how many years I would have to wait until the development of the fine chemical industry developed.

At the door of the warehouse, he opened the gate and passed through the courtyard to the door of the bungalow. When he opened the security door he had installed behind him, he glanced around the room, and everything was still in the same place as the last time he left.

The temperature in the house was a little high at this time, and he looked at the thermometer: thirty-six degrees. That didn't work, he immediately turned on the air conditioner and then the humidifier. The development of smokeless gunpowder at a temperature close to 40 degrees Celsius is very risky, although it is not possible to make a trial production in one day today. However, cooling and humidification are still necessary.

Sun Defa put on a white lab coat hanging on the wall and slowly began to make preparations before the trial production.

It was a familiar feeling to him, as if he had gone back to his first lab class in college twenty-four years ago.

At that time, in the bright and spacious laboratory of the university, Sun Defa put on a white lab coat for the first time, and at that moment a sense of mission and sacredness arose. That's not what a middle school lab can feel.

The first experimental lesson is to prepare the phase diagram of the benzene-water-ethanol three-component system under isothermal and isobaric conditions, right?

The experiment was fairly simple and risk-free. Eight dried 50mL Erlenmeyer flasks with caps, burettes and pipettes were taken to prepare 6 different concentrations of benzene-ethanol solution and two different concentrations of water-ethanol solution.

This is such a simple experimental class, which a primary school student can do when practicing, and it is far less dangerous than the experiments that Sun Defa did later. But Weishenme herself remembers it so deeply?

A sense of sacredness and a sense of mission!

He suddenly figured out that it was the first time he had a sense of mission and sacredness, thinking that he would be able to contribute to mankind in the future!

Hehe, what became of me later? An idler? Eating on rent?

The temperature in the house had dropped to twenty-eight degrees and eighty percent humidity. Not bad, let's get started. Sun Defa didn't know that his expression had become serious, the wind on his face was swept away, and the banter in his eyes had been replaced by sharpness.

Sun Defa took a selfie of every shiyan process in case his friends questioned him. After a few days of hard work, the smokeless gunpowder made of various raw materials was completed one by one, and the test results were sent to the QQ group. It's not a firearm, it's just general play.

First of all, it was made of dragon's beard grass, and when it was ignited, it quickly burned on the white paper, and by the way, the white paper was also set on fire.

Li Ziqiang quickly replied to the post, good job, hair boy, how much dragon beard grass you want!

Sun Defa: Fart, it's useless, the burning speed is too slow, and it's not good to make firecrackers. If the nitrogen content is not enough, the process is useless. Fake.

Then it is made of ordinary absorbent cotton. After ignition, it burns more rapidly on the white paper, which is scorched by the heat. The crowd did not dare to jump to conclusions.

Zuihou is made of absorbent cotton of No. 1 strong cotton. Sun Defa deliberately put it in the palm of his hand, and then ignited it with an exaggerated motion, and almost instantly, it burned out. Sun Defa's palms were not even red at all.

"This is qualified nitrocellulose, and the rest can only be called fire cotton." Sun Defa is rarely a little proud.

The crowd was silent for a moment.

Or Li Ziqiang quickly replied: You dare to do this next fucking time, I'll fly over and ask for your life! Do you believe it or not?

Book friends, forgive the author, I deliberately omitted the process, just in case.
