The explosion of Qin's aerial bomb made it necessary for Qin's state governor's office to purchase a new type of aerial bomb to meet the needs of the space army. In particular, the issue of the charge of aerial bombs. This issue was left to the major arms production companies.

In today's Qin State, in addition to the first few large companies, engaged in the production and development of weapons. There are also a lot of small and medium-sized companies. These companies are chemical, glass processing. and other special metals. Large companies and small and medium-sized companies are competing and interdependent companies. Because these small and medium-sized companies tend to go off the rails. Their research is beyond the reach of the big companies.

The reason for the explosion of the aerial bomb was because of the use of nitroglycerin in diatomaceous earth inside the bomb, and after the advent of nitroglycerin, a large number of people have been working on nitroglycerin. Because this was the most powerful explosive known to the Qin State at that time.

However, nitroglycerin was so powerful that it was extremely unstable at the time. Especially in terms of production, the Qin State did not have the means to produce on a large scale. Research and development in the chemical industry solves this problem. A lieutenant in the engineering corps of the State of Qin solved this problem. Like the Nobel Prize in history, this problem was properly solved by a warm method.

The production problem was solved. But the gas explosion problem is difficult to solve. The way it ignites is very dangerous. Thereupon. Detonator application was born. This is the invention of Bai Ai. However, nitroglycerin still did not solve the problem of how to apply it, until diatomaceous earth adsorbed nitroglycerin. The first relatively reliable explosive in the possession of the Qin State.

At that time, the Celestial Army was in dire need of a weapon capable of mass destruction, because their many flights showed that if they threw stones from the sky, the lethality was amazing. Later grenades began to be used. But the grenade is not operable, the reason is that the time is uncertain. Later, they thought of bombs. This idea also directly led to the birth of the first generation of aerial bombs in the Qin State. At that time, the use of diatomaceous earth explosives was a very advanced weapon, although it was much less powerful. But the charge of an aerial bomb is dozens of times better than that of an artillery shell. The power is amazing.

But after this accident, diatomaceous earth explosives were announced to be retired from the stage of history. Because, the state of Qin needed a more suitable explosive.

However, biochemistry, the predecessor of organic chemistry in the Qin state, has made significant progress in their research, starting with the emergence of picric acid, that is, trinitrophenol. This explosive was first used in the dye industry, but soon it was used in the production of new artillery shells in the Qin state. Like his color, people call it "yellow dynamite." ”

However, at that time, the military had already placed an order for a large number of aerial bombs. The number was around 200, and at that time yellow explosives were looking for a more suitable method for mass production. This is because a large amount of nitric acid is preferentially concentrated on nitroglycerin. As a direct result, the production of nitric acid could not be used in yellow explosives in a timely manner.

Attention then shifted to the study of nitric acid production. This is one of the reasons why diatomaceous earth bombs continue to be used.

Quantitative studies have led to the recognition of the presence of large amounts of nitrogen in explosives. At this time, air studies have also found that there is a certain high proportion of nitrogen in the air. The main thing is that people are determining his specific air content.

In addition, the high temperature and high-pressure compression method are widely used, and people are trying to develop new nitric acid through air compression. Liquid ammonia was developed with this idea in mind.

Large-scale application of electricity in the laboratory. In particular, the use of electric compressors, after continuous research, researchers have finally found a reliable way to accidentally produce synthetic ammonia. This is the main product, the emergence of synthetic ammonia, which has made a new breakthrough in the chemical world.

Ammonia refining no longer extracts large amounts of urea from urine, but instead uses new chemical methods to obtain it. But the research on explosives has not stopped. Attempts were made to industrialize the method of ammonia synthesis. The first small-scale ammonia chemical plant was established in Guyang, north of the Qin State. At the same time, the emergence of ammonia gave Qin the first refrigerant. And the local steel mills began to use ammonia as a human-controllable refrigerant for cold-rolled steel, because they found that the barrels of the machine guns were frozen to become very dense. As a result, a large number of high-priced cold-rolled steel began to appear.

The emergence of ammonia makes the synthesis of nitric acid and ammonium sulfate not a big problem. But the progress of explosives was relatively slow. Agriculturists are more widely used in the configuration of plants in the laboratory, because these are excellent fertilizers for the production of plants.

However, the emergence of synthetic ammonia has solved the problem of nitric acid production in large quantities, and people have begun to reduce the large-scale import and use of saltpeter. Plants producing nitric acid are being used on a large scale.

The emergence of trinitrotoluene, a TNT explosive, gave Qin a new type of safety explosive. This explosive is a very powerful and fairly safe explosive, and even if it is penetrated by a bullet, it will not burn or detonate. Because there is absolutely great security, and it is very powerful. This explosive soon demanded widespread production. The engineering demolition detachment of the Qin Army and Marine Corps was soon equipped with this safety explosive on a large scale, but they were willing to call him "life-saving explosive." "The reason is, they really took guns and shot explosives, and none of the explosives exploded. This made the soldiers carrying the explosives more than happy to accept it.

The appearance of life-saving explosives shows that Qin's chemical industry is speeding up the progress of digesting the great chemical changes brought about by the petrochemical industry. Explosives are just the beginning. And not the end.

After this accident, the Lieutenant's Office finally noticed this brand new explosive. And the new bombs also use this life-saving explosive. Although his production is not very high. Only one medium-sized chemical company produced him. But that's pretty much enough.

To be on the safe side. This time, the Qin State no longer made the aerial bomb very large. It is very small, with only one stone and half stone. Such specifications are mainly based on the amount of charge, and not on the total weight of the aerial bomb.

After experimenting with four bombs. He ordered twenty bombs to be sent to the front line of the Qi State. This kind of bomb was first applied to the people of Qi. It will be the most effective weapons testing ground for the Qin State so far.

Yan Guo, while urging, is trying his best to release the poisonous gas. They experimented on death row inmates, and the results were very good, and the death of death row inmates made people shudder. It's horrible. Even King Yan was taken aback. After a day of stopping. A question was in front of them. Their murderous experiments were carried out in prison cells. Then the battlefield is empty. This question made King Yan feel bored for a while.
