The Weapon Tycoon Who Traveled to Great Qin

This time, Shang Wen only had an hour of class, but suddenly turned Qin's knowledge upside down. The first is that people have started heated discussions. Is the earth under my feet called the earth round? Some people think it is. Some think it is not. Others suggested that the earth is square. The sky is round. Otherwise it will not be called Fangyuan. This is pure nonsense, the prime minister. Some people think it makes sense. Compared to heated discussions. Many people started to run up the mountain. why. Look at the moon at night. With the help of Shangwen's telescope, they began to look at the moon carefully. It turns out that the moon is bumpy. Some people can't squeeze the astronomical telescope. Just look with the telescope.

Since telescopes have become popular in the military. Therefore, many civilian versions of poor quality have begun to flow into the market. The reason why a large number of telescopes can be produced is mainly due to the two new products newly listed on the futures market. Fine salt and coarse salt. Fine salt is used to provide folks for consumption. During the Warring States Period, and all subsequent dynasties. Edible salt has always been a lucrative industry. Yingyu didn't notice this more traditional industry at first, and only discovered this problem when he accompanied Shangwen to the streets. As a result, a new variety of salt was launched soon.

But with the expansion of the Qin State, some inland lakes in the northwest were discovered. People began to find edible salt in these inland saltwater lakes. However, a large amount of coarse salt appeared during the extraction process. These coarse salts contain a lot of sodium carbonate and other salts. Although only two of them are used, they are of great value. For example, the price of sodium carbonate far exceeds that of edible salt. Thus, the salt was preliminarily divided. Fine salt is specifically called edible salt. Coarse salt became synonymous with early industrial salt. However, the extraction of sodium carbonate from these crude salts is still very limited, so some people began to use their brains to research and develop other things.

It is precisely with the help of futures that Qin has a large number of glass and mirrors. Glass is no longer a special product of the Wang family. Began to enter the homes of ordinary people. Some students who had a keen interest in astronomy began to imitate Shangwen's astronomical telescope. At the same time, some surveying retired military officers, non-commissioned officers, and land officials also began to accept the sextant. According to the latitude and longitude, draw some preliminary maps. These Shangwen did not care. What he needs is such an effect. Because these things involve a wide range. Need to inspire specialized talents to explore.

In the electromagnetic field. Qin State began to manufacture compasses on a large scale. With the excellent sealing of glass. A large number of compasses were manufactured. However, the army is not the priority. It is a large number of security trade armed personnel. They need a north arrow to indicate the direction. However, large magnets cannot be manufactured. Because, there is still a lack of natural insulating materials such as resins. The price of the resin is extremely expensive. This thing is only available in the royal family or the minister's family. Even wealthy businessmen have only a small piece. Therefore, this leads to the magnets that can only be made very small. Can't do much. This severely hinders the development of electromagnetics. However, there is still a major progress in electricity. Bai Ai discovered a brand new metal, zinc, through unintentional experiments. There are a large number of lead-zinc mines in China. Especially, in the Qin State, and the newly occupied East Mongolia and other places.

The emergence of zinc has made the battery a step further. At the same time, hydrogen can be produced quickly. This is currently the main source of hydrogen in the development and improvement of glass and new airships.

In terms of gunpowder. Black powder is still the mainstream gunpowder. The slow progress of new-style gunpowder is mainly due to the immense power of new-style explosives. It explodes at every turn, mainly nitroglycerin. Therefore, many people are unwilling to study. The other is the lack of a fiber that can be nitrated. cotton. If this problem is to be resolved, it must have a lot to do with Mesopotamia and India. Otherwise, the smokeless gunpowder will still not be able to break through.

Shangwen actually started planning long ago, and sailing is currently the most effective and fastest way to obtain cotton. You can quickly reach India and the Mesopotamia by sailing. If it passes land, Qin must try its best to clear the battle, and it will be no problem. But where is the driving force? Is it just for cotton. China has better silk fabrics than cotton. Obviously, the allure of cotton is not great.

While Qin State was busy drawing new maps and exploring the mysteries of the universe, Shang Wen was very happy to be here alone. It is not so much a person as a group of people.

After Shangwen's invitation letter was received, Xiao He brought Liu Ji and others to Qin to seek a good future. The invitation letter was issued by Shang Wen himself. Therefore, when the doorman notified Shangwen of this invitation letter together. Shang Wen received several people very warmly.

Because the place is too narrow and tight. Shang Wen had to invite Xiao He and others to the restaurant in the city.

Xiao He walked from Peidi to Shouchun, from Shouchunjing all the way to the west to enter the boundary of Qin State. During the Zhaowang period, Bai Qi, the general of Qin State, conquered a large area of ​​Chu State. Then, they passed Wuguan into Hanzhong, and from Hanzhong into Guanzhong. It took nearly a month in between. After entering Guanzhong, they slowed down. Because, at this time, Guanzhong has changed a lot. First of all, they saw a large tract of land being cultivated by a group of northern nomads, and those farmers were leisurely riding horses and wandering around with shotguns. The gun holding order in Guanzhong was revised once. Allow the farm host to have a certain number of guns in order to control a large number of slaves.

At this time, they also changed into Qin's four-wheeled carriage, because when they came, the four-wheeled carriage was impassable, so they had to change. Anyway, the money was still worthy of money. They don't feel distressed either. In their view, this is justified.

The inn where they stayed is very different from Chu State. And there is a lot of meat, and the price is very cheap. This person Xiao He and others opened their horizons. And I ate beef. This made Fan Kui, who had slaughtered dogs since childhood, felt a little unbalanced. Beef can't be eaten casually. And here in Qin, the ordinary shopkeepers have enough. This made them believe. Coming to Qin to find a future is the right way to go.

Until they saw the prime minister of Qin with their own eyes, they forgot to give a gift. The reason was that Qin's prime minister's dress was very different from that of Chu's official elders. If it weren't for self-introduction, Liu Ji would almost think he was an ordinary guy on the street.

Shangwen was not surprised. Busy to greet the bit into the city to arrange board and lodging. Once in Xianyang City. These people were all bluffed.
