"The bullets used by the Qin people are all fixed-loading bullets. The bullets are all made of copper, and we can make such copper bullets, but the cost is too great. The price of this copper is not cheap. Wang Er, the bullet master of Zhao Guo Ordnance Industry No. 2 Factory, said. Their workshop mainly produces some bullets and shells. With the promotion of fire cap guns using fire caps, Zhao Guo is also actively changing clothes, however, for fire caps. Zhao's chemistry team is studying the composition of the propellant in the cap, and they are studying how to make bullets easier. But the actual effect is not very good.

"Qin's copper can be imported in large quantities from the Western Regions. Our Zhao country lacks too much copper, and there is a lot of iron, but the iron will rust, and the bullets will be loaded into it. There are a lot of problems, and if you use an iron-nosed bullet, the loss of the barrel is very large. Rather than this, it is better to stop using such bullets. Wang Er added.

"Well, got it. Do you think we can make such a bullet? Workshop supervisor Zhao Er asked worriedly. Zhao needs to solve the problem of bullets in order to further replace a large number of flintlock guns, the weapon effectiveness of flintlock pistols has lagged far behind the Qin army, not only the Qin army, but even the Chu army, and the elite troops of the South Korean New Army have begun to use rifled guns on a large scale, and their propellants have also been changed to fire cap type, the range of this musket has more than doubled, the caliber has decreased a lot, but the power has also increased a lot. The upgrade of the musket put a lot of pressure on the Zhao army's weapons and equipment, and the Zhao army imported a batch of fire caps, bullets, and corresponding rifles from the Qin army, and they planned to transform their flintlock pistols into fire cap guns according to the strength of their own team, so that the cost could be greatly saved.

"No, I can't. The principle of the bullet of the Qin army is fundamentally different from the principle of our bullet, the most terrible thing is that the gunpowder used in the copper shell bullets of the Qin army seems to be different, some of them are black powder, some are not, and some are flocculent, this kind of bullet is more powerful, our musket may not be able to withstand it, I think, the best way at present is to replace a batch of bullets. And. Wang Er hesitated at this time.

"What?" Zhao Er then asked.

"Moreover, the principle of this musket is not the same. Although the flintlock pistol could be changed, the way the hammer was hammered needed to be changed, and the most important ammunition was conical rounds. There is rifling, and the bullet can only be improved in this way, otherwise, we will produce it, and it will not be of much use, and the cost will be stuck too much. Wang Er said.

"This is very unrealistic, at most we just take copper to produce some copper caps, produce all-copper bullets, very unrealistic, the army is not equipped at all." Wang Er said very practically.

"Besides. It's just what kind of propellant is in that brass cap, we don't even know what kind of bullet we are going to produce now, I feel like we're going too fast. It is definitely not an accident that Qin Guosheng has produced very powerful bullets, I feel that they have integrated a lot of technology, and some things may be completely unfamiliar with us. Wang Er boldly guessed. Wang Er came according to his own feelings, and the method taken by Zhao Guo for the weapons equipped by the Qin army was to buy, introduce, and then disassemble, and they probed all the things they could find out from them.

"This. Well. I know. Zhao Er was a little unwilling, but he was also very helpless, after all, what Wang Er said was a fact, Zhao Guo wanted to catch up with and surpass Qin State at once, this is indeed very unrealistic, Zhao Guo can indeed make such a bullet, but can the things in it be the same? The Qin army had already used smokeless gunpowder bullets, while Zhao Guo didn't even know what smokeless gunpowder bullets were. They didn't even know what the propellant in the brass cap was.

"Re-study the study. Don't be in a hurry. Don't be in a hurry. Zhao Er waved his arm and said. Then he walked away. In many cases, he needs to cooperate with the workshops of other factories to carry out relevant experiments, and the progress of such experiments is relatively slow. Because Zhao Guo does not have a corresponding special laboratory, many experiments are carried out by masters and apprentices, and the research fees given in the factory are not very sufficient.

Sinjeong, South Korea.

"I know what the bronze hat under Qin Jun is?" A young man excitedly rushed into the lab and shouted. This is the laboratory of the Xinzheng Arsenal in South Korea, and their main task is to imitate some weapons of the Qin army, such as pistols, portable machine guns, and corresponding bullets, but in the bullet link, the Koreans and Zhao people encountered the same problem, and the Qin army used firing bullets, that is, using fire caps. And the Koreans couldn't understand why muskets could be used in this way. So they imported a batch of bullets and did not equip the army, but conducted special research, focusing on the propellant in the fire cap. Because the South Korean New Army will be equipped with a batch of these new firing cap guns on a large scale. The people of Zhao called it a fire cap gun.

"What?" All the researchers asked curiously.

"It's mine mercury. Of course, there are other propellants, because I've found that using nitrified inner propellants can do the same thing, but only. Mercury is more sensitive and can be emitted after a slight collision. I think that the Qin people must have used such a substance, they loaded it with copper caps, and then used special copper bottles, so that the bullet was made as a whole, and the chemical energy of the gunpowder was converted into the kinetic energy of the bullet by the impact of the machine. The young man said excitedly.

"Hmm. That's a good point, you get this project out right away. If you develop it, your rewards will be indispensable. A middle-aged man said immediately at this time.

"Thank you, Director. I'll go. I've written it all. Our new army in South Korea has its own weapons. The young man left excitedly.

"Be careful, this thing isn't for fun." The middle-aged man shook his head and said. High financial incentives. As well as the improvement of treatment, coupled with the improvement of specialized research institutions in South Korea, this allowed Koreans to study and reverse the military products of Qin. This is definitely not good news for Qin, but fortunately, Qin's industry is becoming more and more complex, and many things cannot be manufactured by a single discipline, for example, Zhao's industrial system needs to be improved so that they can change and study new military products.
