It's really boring, so I won't play it. “

On Ma'anshan, looking at the Qing army that came like a tide and retreated like a tide, Li De was like a child who had been cheapened and sold well, pointing at the retreating Qing army and laughing.

"It's a pity, there are still too few such good artillery, if there are four or five hundred more of him, he will definitely be able to leave the Qing army that has just rushed to the front." After laughing, Li De couldn't help but sigh again.

It is true that more than a hundred mortars look like a lot, but in the face of a huge position of thousands or tens of thousands of people, it will seem a little powerless.

The reason why the attacking Qing army was instantly defeated was mainly because it was caught off guard.

Although the mortar bombardment just now was fierce, the casualties caused by the attacking Qing army were estimated to be more than 1,000. If the Qing army can organize an attack, I believe they can quickly attack the foot of Ma'anshan.

"You guy just got it, there are four or five hundred more, do you think it's cabbage?" Li De's words made Zhang Rui, who was on the side, twitch the corners of his mouth and said.

"King Han, that's not what I said, isn't this also for the sake of our army's combat effectiveness, if I can have more, of course it would be good to have more!" Li De replied with a smirk.

"You don't understand, this thing, it's easy to build this artillery, but the real difficulty is the shell." Zhang Rui replied.

"Ordinary black gunpowder can explode, but it's not very powerful. And this powerful yellow powder is almost equal to the price of gold. This cannonball is equivalent to dropping a ball of gold. ”

"What? So expensive? Li De exclaimed.

"Otherwise, you think that when the cannon goes off, there will be ten thousand taels of gold, how did you say this?" Zhang Rui said.

"That group of dogs is also a one-shot matter, where is it worth this price, I feel distressed by this cannonball. Sure enough, it's better to make less. Li De couldn't help but feel sad.

"That's not to say, the lives of my brethren will always be the most precious thing in my heart. The reason why shells are expensive now is because the manufacturing process has not yet come up. When the process comes up in the future, the price will naturally decrease, and this yellow powder will become the mainstream trend of the future battlefield. Thinking of the humiliation suffered by modern China during World War II, Zhang Rui couldn't help but sigh.

Yellow gunpowder generally refers to picric acid, TNT or nitroglycerin.

Picric acid and TNT require a series of chemical purifications, so it is not easy to manufacture, and Zhang Rui chose Nobel's diatom nitroglycerin.

Compared with picric acid and TNT, diatom nitroglycerin raw materials are relatively easy to obtain.

In diatom nitroglycerin, the most difficult to obtain belongs to nitric acid, and Zhang Rui has no other good way at present, so he can only use the most primitive method to obtain nitric acid by dry distillation of saltpeter.

However, the dry distillation of nitric acid has a large loss of equipment, and the efficiency obtained is not high, so you can imagine the money and silver that need to be spent.

At the same time, in order to ignite diatom nitroglycerin, it is also necessary to produce thundermercury. Thundermercury also needs to consume nitric acid, so Zhang Ruicai said that the price of this cannonball is equivalent to gold.

"King Han, you don't have to say it so literately, I don't understand it anyway." Li De replied with a smile.

"Well, telling you is equivalent to playing the piano to a cow, and I don't bother to say it. Taking advantage of the time when the Qing army has retreated, organize all the things that should be organized, and prepare the things that should be prepared, it is estimated that after a while, the Qing army will organize men and horses to attack. Zhang Rui commanded.

"Yes, King Han, I'll go and order." After Li De finished speaking, he immediately left in a hurry.

Looking at Li De's departure, Zhang Rui couldn't help but think back to the scene when he first took Zhilian Mountain two years ago.

"At that time, it was also full of dangers, and I only had a broken knife in my hand, so I survived. It's still in danger, can I get through it? Zhang Ruinan said.

As he spoke, Zhang Rui turned his eyes to look down the mountain again. The eye touched on the twelve revolver machine guns that he had specially made for this war.

"Hehe, what am I worried about? Wild pig, you are very powerful, but I do have a pig-killing knife in my hand. Thinking about it, Zhang Rui couldn't help but feel better.
