This was not the way Hong Tao invented. Later Europeans conquered the American continent in this way. However, they did not have the strong pressure of crushing themselves at that time, so they fought with the local Indians for hundreds of years. The Indians were almost killed, and the white people also paid a great price. This was a protracted war that no one could easily do.

With the lessons of other people's success and failure, Hong Tao planned to do better than the Europeans back then, and directly shocked the Indians with powerful force and prevented them from making too fierce resistance. Although it might have been bloodier and crueler at the beginning than the methods used by white Europeans back then, it could effectively shorten the resistance time of the Indians. Relatively speaking, it would reduce more casualties and injuries.

Sometimes things are so strange. You are clearly kind-hearted, but the result may not be good. If you become more vicious, the result may be better. This is also very consistent with dialectics. Things always have two opposites, which side is good and which side is bad, and it is uncertain. It only depends on how you use it, and also on what angle you analyze it from.

Hong Tao came to Sun City this time to speed up his expansion. He didn't care about South America now. The natural environment in the tropical rainforest is not suitable for survival. It is easier to occupy Mexico first and then develop northward.

As long as you have a fleet and cavalry, you can have the coastline of the western North American continent, the Great Plains in the central part, and the mineral areas in the northeast, and there are enough places to be distributed to your followers. Just using empty mouths and white teeth to fool people can only work in a short time. People will lose their enthusiasm and motivation if they don’t see hope, so the process here must be accelerated.

"How is it? Is the production of fire cotton still going smoothly?" After the meeting, everyone went to work on their own. Hong Tao followed Bush to the yard of the laboratory.

Due to the expansion of Sun City, the yard of the chemical laboratory was already in a densely populated area. Following Hong Tao's advice, Bush moved the entire chemical laboratory and production workshop to the east of Sun City. The land there is not suitable for planting crops, and no one will live there. In the large empty field within a few miles, there are only four lonely buildings, which are arranged diagonally and are far apart. The two on the east side are oil fractionation workshops and fire cotton rubber workshops, and the ones near the west are laboratories and pesticide workshops.

"It went smoothly. After several accidents, it was caused by the slaves' improper operation. After gradually becoming proficient, it would be much better. I want to show His Majesty something. Do you know what it is?" Seeing that he had already reached the edge of Sun City and there were no people around him, Bush took out a small bottle wrapped in a leather hood from his pocket and handed it to Hong Tao in a mysterious way.

"What's this..." Hong Tao took off the leather case and shook it through the bottle. There was a small pile of white translucent crystals inside. You must not know what it was by looking at it alone.

"Your Majesty, beware, this thing is poisonous!" Seeing that Hong Tao was about to open the bottle stopper, Bush hurriedly reminded him.

"Well, I know." Hong Tao was still very cautious. He slapped the bottle with his hand, and didn't smell anything. He was getting closer and smelling it, but it still didn't smell.

"You really stumped me, just say it, how did this thing come up? What's the use of it? You can't just be used as poison!" Shamelessness sometimes means modest. Hong Tao does not have the habit of slapping the swollen face and pretending to be fat. He doesn't know, but he doesn't know. Even if his opponent is a child, he can't say he knows. It's not that he doesn't like bragging, but that bragging like this is easy to reveal the money and the gain is not worth the loss.

"It is synthesized with relatively high purity nitric acid and silver powder. When it sees light, it will slowly turn black. It only takes a small spoon to poison a wild boar. When it touches the skin, it will appear black spots, which will not hurt or itch." Bush talked about his understanding of this substance, and it seems that he has done a lot of experiments.

"It may be called silver nitrate. I only know that it can be made into something called photo paper, a photosensitive material. I don't know if it has any other uses." Hong Tao was helpless at this time. The high school chemistry knowledge in his mind was inconsistent. It was already a lucky thing to be able to make three acids and two alkalis. Most compounds do not know much about the properties and uses. I can't even know whether this crystal is silver nitrate or not, but I just feel it's confusing.

"It's of great use! Look at this again, is it the kind of fire hat you have always mentioned?" Bush didn't know what he had made of, and grinned happily, then took out a small bottle from his pocket and handed it to Hong Tao. When will he be the happiest when he is a student? It's not that he has done the exam or learned all the skills of the teacher, but that he has surpassed the skills of the teacher.

"Fire hat! Will it explode?" The small bottle is stuffed with cotton, mixed with a few small pills the size of rice grains. After Bush said the word "Fire hat", Hong Tao immediately pulled out the plug, took out one from the cotton ball, and pinched it between his fingers and looked carefully.

"It can be fried, I'll demonstrate it to you." Bush smiled and took the small pill from Hong Tao's hand, put it on a relatively flat stone, then found another stone to hold it in his hand, raised it high, and patted it down.

"Bang!" A crisp sound came from between the two stones, with almost no smoke.

"Silver nitrate has this function?" Hong Tao was a little stunned. He really didn't know about this reaction, and he had never heard of it.

"Hehehe, not only the silver nitrate you mentioned, but also the sulfur and red phosphorus were added. Since you left last time, I have been wondering if you can use match medicine to make the kind of fire hat you mentioned. Once, when I was doing an experiment, an imperial silver coin in my pocket accidentally fell into concentrated nitric acid. I didn't find it at that time. Later, when I used the bottle of nitric acid, I saw that some of the silver coins had been dissolved. I simply heated it up and continued to see what they would become. This is what I finally got, but it was not too much

Pure, I tried it with sterling silver powder, and the effect was better. At first, I didn’t know it would explode, but I only knew it was poisonous, so I put it aside. Later, I added a lot of things to the red phosphorus and sulfur, but it was not easy to use. Then I remembered whether I could add some of this thing, but I didn’t expect it to be done! It took me half a year to test countless recipes, and finally I figured out the ratio of these three things. The silver nitrate ratio is a little more sensitive, and it will explode if I throw it hard to the ground."

It seems that Bush did not intentionally synthesize silver nitrate crystals. Like many chemists in later generations, he accidentally discovered that a certain substance has certain properties. As the saying goes, there is no way to get wet when walking by the river. This sentence is also very suitable for scientific experiments. Detailed observation and tireless experiments are a road to success. You cannot rely solely on luck, but you can't do it without luck.

"Good boy, you are much better than the teacher. Take a few steps and I'll try it in the laboratory. If it's really suitable, this is not a problem with the fire hat. Do you know what you invented? It can kill many people in Swan's army!" Hong Tao didn't know what to say. This was the biggest surprise that people of this era brought to him since he traveled through time. The bottom fire! If there is a reliable bottom fire, coupled with Qi Zu's technology in metallurgy and mechanical processing, he can improve the weapon system by several levels, almost reaching the level of World War I.

That afternoon, there were continuous crackling sounds in the yard of the laboratory. Hong Tao held a small hammer and smashed a row of dark yellow millet grains on an anvil with different forces. Some were directly smashed, while others were smashed without any reaction. At this time, he exerted a little more force, and then another crisp sound appeared under the hammer.

As it turns out, the sensitivity of this mixed material produced by Bush is very suitable for use on the bottom of the fire. It will not be too easy to fire or too difficult to fry. As long as you master the mixing ratio of silver nitrate, you can always find a suitable primer formula.
