Because some readers mentioned this issue, I feel that I need to make a special explanation.

First of all, it is clear that there will be no advanced technologies in this book, including chlorine, electricity, and sniper rifles, which will not be used on a large scale.

But the reason why it still appears in the book is that it is necessary to write about the background of the times at some point.

The middle of the 19th century was a time of rapid development of science and technology, but the occult was still in vogue, and all of this era was actually a rather absurd and contradictory age.

Steampunk? Stonepunk? A mysterious world?

All I can say is that reality is more ridiculous than the story. Stories need logic, reality doesn't need them at all.

Here are a few examples!

Just like the 'Truth Machine' mentioned in the article, this thing is inserted into the human head with a conductive copper wire, is it scientific? Not scientific at all! But whether it's copper wire coils, electricity, or even the study of the brain, it's all serious scientific things!

Doesn't that 2-ton grenade feel funny? But in fact, by the time of the 2 World War, Krupp built a cannon of more than 300 tons, would you believe it?

Before the advent of the telephone, its name was the talking machine, in fact, the telegraph had been invented during the Napoleonic Wars, and the well-known Rothschild family relied on the telegraph to make the first pot of gold by making a difference in information.

As for the sniper rifle, the Whitworth rifle is true, and it is also true that a high-ranking general of the Northern Army was killed in the Civil War. However, this thing is very difficult to use, and the recoil is so strong that it can blind people's eyes.

Aluminum is a precious metal, and in the previous volume it was mentioned that Armand gave Peter Davis an aluminum beauty, which is really expensive, more expensive than gold!

Chlorine is not a new thing, it has been made in the laboratory for a long time, and of course it is not possible to use it on a large scale.

All in all, the 19th century was a rather rather mysterious period.

Everything is possible, but everything is impossible!

Even if the rear-loading gun has been invented, the front-loading gun is the most recognized;

Although the skirmish line was invented, it was the most awesome to line up and shoot;

The "Manifesto of XX XX" was published in 1848, but at the same time, China had only finished fighting the Opium War, and there was no such thing as workers.

At that time, people imagined that they could fly, but either they had gunpowder canisters tied to the back of their buttocks, or they had wings on their backs;

There were also people who became interested in the moon, so it was common to see in the newspapers of the time that someone had made a telescope several miles long, which was said to be able to magnify thousands of times and be able to see the moon people on the moon!

……

The wheels of the times are rolling forward, and the Indians are certainly the last in the long-distance races, but the Americans are no better, and they themselves are all messed up.

U.S. President Washington died in 1799, but he was killed by 'bloodletting', because medical research at the time believed that bloodletting could maintain the balance of the body's 'four major fluids'. It is said that 3.75 liters of blood were released in 12 hours, while the average blood level in a normal human body is around 4.7 to 5.5 liters.

If you still don't understand what these things we think were common today meant to people back then, let me give you another example as a final explanation.

You've probably heard of things like 'nano-magnetic field resonance therapy' or 'quantum light technology' or 'gravitational wave stock speculation'?

Chlorine, electricity, and sniper rifles were much the same at the time.
