Although the microscopic physical rules of the Eternal Kingdom are very unscientific, at the macro level, there are also chemical reactions that should be found in the real world.

Since there is no arbitrary gate, Kant's team carried not many chemical raw materials this time, mainly concentrated nitric acid and concentrated sulfuric acid contained in aluminum cans.

Nitric acid is an essential raw material for the production of all strong explosives. Whether it is TNT, nitrosilicate, nitrified cotton, nitrified glycerin, or even detonators used for detonation, nitric acid is required as the raw material.

In the Eternal Kingdom, all nitric acid is produced by the Chemical Alchemist Workshop of the Scientific Inquisition, and this part of nitric acid is also used to make thermal weapons filled medicines used by the Scientific Knights.

The concentrated nitric acid and concentrated sulfuric acid in aluminum cans smuggled by Lucas is to produce one of the oldest strong explosives - nitrosized cotton.

Under the deliberate guidance of the Science Inquisition, the scientific and technological tree points in the Eternal Kingdom are very strange.

Generally speaking, the local scientific and technological level is approximately equivalent to the Earth in the early 20th century. The thermal weapon technology, metallurgy technology and chemical technology of the Science Inquisition are probably at this level.

But the science and technology of the Eternal Kingdom has obvious shortcomings compared to the earth.

The most obvious shortcoming is that there is no petrochemical technology or any polymer organic materials in the area, and the first oil well on Earth was laid as early as the mid-19th century.

But if we want to say that the Science Court has lagged behind in its technical level, they not only developed mature cable broadcast technology, but also successfully achieved mass production of advanced technologies such as protein factories that artificially synthesized food, which cannot be produced by the Earth in the 21st century.

In terms of explosives, several mainstream strong explosives that appeared on Earth in the 19th century, such as TNT, nitroglycerin, nitrified cotton, Nobel explosives, and the Science Inquisition all have corresponding mature technologies.

The reason why Lucas chose to prepare nitroscopic explosives is simply because nitroscopic cotton is the simplest one among all strong explosives.

Even on earth, nitroscopy was the earliest strong explosive. It was made by French chemists using carbohydrates such as cotton, starch, and wood in concentrated nitric acid. Therefore, the earliest nitroscopy was once again made into "wood explosive".

Since high-quality nitrocellulose explosives require extremely high purity requirements for cotton fibers, if the dehydration and centrifugation process is lacking in the dehydration and centrifugation process, the power of nitrocellulose explosives will be significantly reduced and the properties will become very unstable. Therefore, from the invention of nitrocellulose explosives to the final popularization, it has gone through decades of process improvement.

However, these problems are not a big deal for wizards like Lucas.

The Science Referee used nitroscopy as the main launching drug for the scientific knight's thermal weapon. It has been unknown how long, so the relevant processes have been extremely mature. Kant also brought a large number of high-purity cotton fibers produced by the Science Referee, which successfully solved the long-standing problem of "cotton fiber purification".

For wizards, nitroscaling explosives have two irreplaceable advantages compared to other types of explosives.

The most important point is the explosiveness of nitroscotton, which can be manually controlled by adjusting its nitrogen content.

Nitrified cotton with nitrogen content above 12.5% ​​is extremely dangerous and burns when it encounters fire and may explode when the temperature exceeds 40℃. However, nitrified cotton with nitrogen content less than 12.5% ​​is relatively stable in nature, but after being heated or stored for a long time, it will gradually decompose and release acid, reducing the ignition point. Generally speaking, nitrified cotton with nitrogen content of 12% can achieve a good balance in stability and explosiveness.

For comparison, nitroglycerin commonly used by online time travelers is too explosive. Even if time travel can produce concentrated nitric acid alone (basically no chance), the transportation process may fry the entire laboratory into the sky. Even modern chemical laboratories, most of them will not allow the preparation of nitroglycerin.

Although Nobel explosives reduce the explosiveness of traditional nitroglycerin by adding a large amount of "impurities", its characteristics are too non-explosive, which require special detonators to be detonated.

The reason why the detonator is called "lightning" is that it is named after its initial charge of pulp mercury and has been used to this day. The process of pulp mercury itself is not complicated: simply put, it is the product that dissolves mercury in nitric acid, mixes it with alcohol, and finally reacts.

However, mercury is not an easy-to-get chemical raw material, and even the Science Inquisition does not have much in hand. Just obtaining the materials for making explosives has already made Lucas' trump card. Even this legendary wizard wanted to smuggle another batch of more difficult mercury, but not enough.

Not to mention, mercury can easily form mercury vapor in a confined space, which kills people with invisible toxicity. In addition, the heating process required to purify high-purity alcohol is extremely dangerous for explosives factories. Therefore, Nobel explosives can obviously be excluded from Lucas' explosive production plan.

In addition, the second advantage of nitrified cotton explosive is that it is simple in production technology. The main materials only require three types of concentrated sulfuric acid, concentrated nitric acid and high-purity cotton fiber. These three raw materials can be found almost easily in the raw material databases of various chemical alchemy workshops in the Science Inquisition. Not only are the reserves large, but the defense is not too tight.

During the explosive production process, it is only necessary to soak the high-purity cotton fiber in the nitrosulfur mixed acid solution for a period of time to complete it. There is no need for additional processes, which greatly reduces the possibility of accidents during the preparation process.

However, even though the materials used to make nitroscopic explosives are ready-made, Lu Yang still has great skepticism about Lucas' underground explosives workshop.

The structure of this underground chemical workshop has been specially designed. More than ten breathable holes are opened in the middle production workshop for ventilation. A very deep refuge passage has been dug next to the production workshop. This thing is for escape. In case of uncontrollable chemical reactions, you can use this to escape - the premise is that everyone's reaction is fast enough and their legs are flexible enough.

However, in confined space, the role that this shelter can only be at the psychological level. If something really happens, at most it is the difference between a dead body without a dead body and a dead body without a dead body.

The moment he entered this underground workshop, Lu Yang decisively slapped the Yiyi Door on the wall, leaving the three of them hiding behind the invincible Yiyi Door, leaving only a small gap to communicate with Lucas.

Seeing this, Lucas didn't care, but smiled and said, "Our underground alchemy workshop is in a simple manner, which makes the three saviors laugh. However, what we did was just working hard, and it was no big deal to take the risk of this explosion. Kant has rich experience in chemistry and alchemy. If he is watching, nothing big will happen in general!"

But what I worry about is the extraordinary situation!

Before Lu Yang could complain, Kant bowed and said, "President Lucas, I'm sorry, today I brought these raw materials for nitrocellulose. The raw materials for making high-definition mirrors, because the container is too fragile and inconvenient to carry, we had to abandon them all."

When Lucas heard this, his face suddenly became gloomy: "It's not your fault. There may be a traitor among us! If we can't catch this traitor, let alone lose a few mirrors, even the entire [Seven Stars Saints] will perish in front of us!"
