Opening game, American Tycoon

The mission of the empire is of course sacred. This sacred mission is essentially for development and expansion, but of course expansion is also for colonization.

The most brilliant and exciting words are just to cover up the essence.Of course, sometimes you will believe him when you tell a lie.

Whether it is for colonization or for the cause of human liberation, the development of empires will always face various difficulties and enemies.

But who is the biggest enemy of the empire's overseas expansion?

Never the local natives, not even the European and American powers.

But the most inconspicuous mosquito!

Don’t underestimate the mosquitoes, it’s this inconspicuous little thing that makes European countries stop in Africa, and it will even trip up the colonization of the great powers.

Diseases such as malaria and yellow fever transmitted by mosquitoes have always been the worst enemies of tropical colonies.

During the "Imperial Expedition", the African Legion lost more than 30% of its personnel. Almost all of them died of various diseases, and the most direct reason was the diseases brought by mosquitoes and flies.

In order to resist mosquitoes and flies, all houses in Africa and tropical colonies must be equipped with screen windows and screen doors. Even Emperor Zhu specially invented elastic hinges with springs that can automatically rebound for the installation of screen doors.

It was the mandatory use of screen doors and screen windows, coupled with the use of new mosquito nets, that allowed Daming to gain a firm foothold in Africa, but even so, the imperial colonies were still plagued by tropical diseases such as malaria.

After all, it is impossible to defend just by defending, and more importantly, to kill!

Only the use of drugs such as mosquito coils to kill mosquitoes is the most effective protection. What can be used to kill mosquitoes?Huaxia commonly used wormwood to smoke mosquitoes. Although the effect was mediocre, the combination of screen doors, screen windows, and mosquito nets also greatly reduced the incidence of malaria in the colony.

Mosquitoes not only had a direct impact on the empire's colonization, but agricultural pests also threatened the empire's agricultural production, whether it was to stop the threat of infectious diseases such as malaria, yellow fever, or prevent crop failure during outbreaks of pests, including locusts. threat, all require research on a pesticide.

However, limited by the level of technology, Emperor Zhu finally chose natural insecticides-pyrethrum and deer vine root powder. The former was processed and sold half a century ago, and deer vine root powder was also sold as it was almost 30 years ago. It is sold as insecticide powder. When it was introduced and planted more than ten years ago, Daming did not use pyrethrum powder or deer vine root powder as in Europe and the United States. Instead, it used modern chemistry to extract the active ingredients and made insecticides for mosquitoes. Culling and agricultural insecticide.

Although the effect is average, it is better than nothing.

However, it is also the use of these types of natural pesticides that have led many people to see the benefits of pesticides to agriculture and invest in pesticide research.

Shen Mingdong, a professor of chemistry at Zhongdu Imperial University, is also conducting similar research, but unlike others who tend to study natural pesticides, he puts more energy into chemical pesticides.

"If chlorine gas can kill people, it must also kill insects!"

It has to be said that Shen Mingdong's thoughts were very straightforward. After knowing the serious damage caused by the chlorine gas used by the military to attack Brazil, he came up with the idea of ​​chlorine gas.

But how to use chlorine to kill insects is obviously a problem.

In the past few years, Shen Mingdong and his assistants have been conducting chlorine-based synthesis experiments in the laboratory.Although the experiments are not successful again and again, there are always some gains.

On a sunny day, Shen Mingdong, with a dozen assistants, was busy working around a large pile of glass bottles in the chemical laboratory as usual. The yellow, green and green things in the bottles and the gas masks they wore reminded them People — these experiments are a little bit dangerous.

The so-called experiment, most of the time, is a process of trial and error. Why did the Edison laboratory destroy the golden age of inventors? To put it bluntly, it was because dozens or hundreds of people were more efficient in trial and error, and led student assistants to carry out Shen Mingdong, who tried and made mistakes, was of course very efficient.

Over the past three years, they have conducted numerous trials.

Today seems to be a very ordinary day. Ye Zhiqiu, standing by the windowsill, directly injects chlorine gas into benzene and dissolves it. During this process, looking at the sunlight shining on the test vessel, he sees that the benzene turns yellow-green. , The tail gas is passed into the calcium hydroxide solution.As the experiment progressed, when he saw that the solution suddenly became cloudy, he began to observe the thermometer, and when he found that the temperature was rising rapidly, he immediately shouted.

"Mr. Shen, its temperature has climbed nearly ten degrees in a short period of time. What should we do next?"

"Should have sparked a reaction,"

After thinking about it, Shen Mingdong said.

"Try to increase the chlorine supply, then cool the temperature with ice water, pay attention to monitor the temperature."

In this way, under the command of the professor, Ye Zhiqiu and his classmates got busy immediately.The reaction temperature is controlled between 40 and 60 degrees, and the supply of chlorine gas is guaranteed.After a few hours, they got some mother liquor of recrystallization.

……

This is just an experiment. The "999" on the test record number is also the so-called "999" compound.In the end, some yellow powdery objects were obtained. As for the effect, further experiments are needed.

The weather was fine that day. As usual, Ye Zhiqiu and his classmates opened the cages containing locusts. Soon, the laboratory was full of locusts.

"Spray 20 grams and try it first."

With the help of the powder sprayer, the powder was blown away and then blown into the test room through the pipe. At this time, Ye Zhiqiu and the others were still chatting there, this was just one of countless tests, almost none What expectations does anyone have for it? Even Professor Shen Mingdong himself did not participate in this experiment.

"Look, there are locusts falling!"

Suddenly, a sharp-eyed classmate shouted loudly.

"Didn't it fly to the ground..."

Before Ye Zhiqiu finished speaking, the densely covered locusts in the experimental cabin fell on the ground like raindrops, and through the glass windows, the dumbfounded people all stood there like idiots.

"This this……"

The dumbfounded Ye Zhiqiu was so surprised that he couldn't speak. After a while, he finally spoke.

"Could it be the same as the last experiment, just nerve paralysis."

In previous experiments, they also obtained some synthetic compounds, but the effect was not satisfactory. At most, they could only kill small pests. Pests like locusts were only temporarily paralyzed.

"I don't look like it. It works very quickly. How long does it take? Even nerve paralysis won't be so fast."

"It must be so, "999" must be highly toxic, we can test it with white mice again."

Facts have proved that those locusts were killed, and the death was so complete that none of them survived.While they were cheering for it, when they replicated the experiment again and wanted to synthesize compound No. 999 again, they unexpectedly found that the experiment failed?

How could this be?
After hearing the news, Shen Mingdong and his assistants were all in confusion. No one knew the answer, but what is certain is that they opened a door—the door of organic chemistry.

In another world, this compound is called hexachlorinated benzene, commonly known as "666", which has contact killing, fumigating and stomach poisoning effects on insects, and is industrially synthesized by benzene and chlorine gas under ultraviolet irradiation.

In the following time, they continued to conduct experiments, but they were still unable to replicate the previous products, until occasionally after another success, when they were constantly checking the experimental steps, Ye Zhiqiu looked at the bright sunshine on the windowsill. On the experimental vessel, he who repeatedly recalled the synthesis steps of the previous experiment suddenly murmured to himself.

"Could it be that you need light? Need sunlight?"

Light!
On this day, God said, let there be light, so there was light!
