The grenade is not simple in structure, but it is not simple to do it all by one person, which is not only time-consuming and labor-intensive, but also very dangerous.

All kinds of endless problems, one after another, take a small insurance bolt as an example, the bolt of the civilian industry is generally fixed with a circlip, or fixed with a nut, but the grenade is not, on the battlefield, who has time to take the circlip and nut! It has to be a one-shot pull. So Yang Wenli thought about it again, and then thought of using lead to fix the seal, one end is similar to a nail, the lead is soft, and the amount is not much, it is really easy to pull it out, but the bolt is fixed so that it will not fall for no reason.

There is also a delayed fuse, which has to be passed to the center of the double-base explosive, how to ensure that the fuse has not ignited to the end and will not detonate the explosive? Later, Wang Rucheng used a small bamboo branch as a sleeve to solve the problem, the middle of the bamboo branch is hollow, you can wear a fuse, and the fuse can be isolated from burning inside, which can naturally avoid early ignition of explosives.

There are also fire cable holes, two bolt holes, these three holes are very small, so the drill bit must be a big deal, how to ensure the toughness of the drill bit? This again brings us to the issue of basic materials.

And how to put the steel balls in the grenade? How much does it hold? It's all a problem.

Of course, as long as these problems are solved, the follow-up mass production is not a problem, Yang Wenli has told Wang Rucheng to subdivide each process as much as possible, especially the preparation and packaging of dangerous double-base explosives, each person only does one or a few simple processes, practice makes perfect, a person feels very difficult problems, it is not difficult to decompose.

Yang Wenli and Wang Rucheng spent a lot of effort, and finally produced the first grenade, this grenade is not simple, it has created a number of world firsts, it uses a new type of smokeless double-base explosives, the world's first wire, car out of screws and nuts, which is a sign of modern industrialization, as well as the use of fire cables, etc., these are Yang Wenli learned from the experience of his predecessors, overnight, oh no! It should be said that it is to learn from the experience of future generations, because those people are not yet alive.

"Archon, let's go and try! How about seeing the power of the explosion? Wang Rucheng, who was on the side, looked at the small and refined grenade, and proposed excitedly.

"You can, but this grenade, whether the explosion is successful or not, does not mean that the technology is mature, in terms of explosives, steel balls, ignition efficiency, delayed fuse time and other aspects, you need to lead your men to continue experiments, measure the most correct value, only then can it be considered a successful development, understand?" Yang Wenli, who was also excited, did not forget to tell him.

"Whoa! I get it! Wang Rucheng nodded in agreement, and reached for the grenade, he couldn't wait to see the explosive effect of this new type of grenade.

"Huh!" Yang Wenli smiled and gave him the grenade, and several people went out of the workshop area and found a remote place, Wang Rucheng couldn't wait to throw the grenade, Yang Wenli stopped him and said: "Wait first, we must set up wooden targets with different distances to test the killing effect of the grenade." ”

Then he turned his head and ordered his slaves to do this, and the slaves either collected the planks or called the carpenters to make them, and it was a long time before they finally set up the target area.

"Ru Cheng, when you pull out the latch, pull the ignition grenade and throw it out, you have to lie down immediately, the explosive fragments and steel balls of the grenade will splash around, and you can ensure safety by lying down, understand?"

"Hmmm! Archon, step back a bit. Wang Rucheng nodded in agreement.

Yang Wenli dodged from a distance, using a telescope to observe the effect of the explosion, only to see Wang Rucheng pull off the pull ring, throw it into the target area with all his might, and hurriedly lie down in the snow.

After a few seconds, only a loud "boom" was heard, and the planks were crumbling.

"Haha! Good! It worked! Wang Rucheng quickly got up from the snow, laughed and said, and rushed to the target area to check.

"Wow! …… My good boy, Great Commander, come and see, this power is so fierce, if you throw it into the Tartar queue, it will definitely blow up a large area, our Black Armor Army, no longer have to be afraid of the Tartar's 100,000 army, how much he comes, we will bomb many of him, and they will not return. ”

Wang Rucheng saw that the wooden planks were full of holes, and some of them were even blown up, and the targets within a radius of about ten meters were not spared, so he shouted loudly.

In fact, Yang Wenli could see clearly with a telescope, but he still stepped forward to inspect the site.

After watching it, Yang Wenli also smiled from ear to ear, the explosion effect was a first-class good, not worse than the grenades during World War II, so Yang Wenli immediately instructed Wang Rucheng to say: "Rucheng, take this grenade data as the benchmark, hurry up the experiment, find out the best plan, and step up production, our black armor army needs this kind of easy-to-carry high-power grenades, each person is equipped with at least three, and first make 100,000 grenades, haha!" I don't think he dares to come to Eternal Life Island. ”

"One hundred thousand? Commander, I'm afraid we won't have enough raw materials! Wang Rucheng interrupted Yang Wenli's YY pouring cold water.

"If you don't have it, go buy it! We still have bone china and glass mirrors, what are we going to keep them for? All go buy raw materials. Yang Wenli waved his hand disapprenosingly.

Indeed, although the grenade is small, if you multiply it by the huge number of 100,000, first of all, the iron material is not enough, and the other materials are enough, which is all to blame for the sets of giant casting molds made by Yang Wenli, and the iron material is wasted too much.

"I'm afraid that Pyongyang Mansion is gone, and this time I may really go to Maoshan Iron Mine to buy it, but I don't know if the Li Dynasty government is willing or not." Wang Rucheng said with a sad face.

"Alas! That's a problem. Damn, we actually have a large iron mine in Liaodong, but in the area of Benxi in Anshan, there is still a nest in the Tartars. provoked Lao Tzu to get angry, I directly led the army to level the Tartars, and all the problems were solved. Yang Wenli nodded in agreement, and said viciously.

“……”

Wang Rucheng has nothing to say, this commander is too unreliable to speak, these thousands of soldiers of the Black Armor Army want to level the Tartars with an army of 100,000 and nearly a million troops, it is simply a fool's dream.

"Alas! Let's wait for the beginning of spring and after the ice and snow melt, let's see the situation! Now all this, it's too early to say anything, the situation is very changing, it is possible, we all have to leave Changsheng Island and go to a place further north to choose a place to hide and develop.

The existence of the Tartars is currently beneficial to our army, they have become the number one enemy of the Ming Dynasty, and it is not appropriate to seriously weaken their power. ”

Which mountain to sing which song, Yang Wenli used to be a patriotic young man, and he also had feelings of worrying about the country and the people, but now he is self-centered, just thinking about sitting in the Jinluan Treasure Palace, and even the Jiannu he has always hated can endure it for the country.

Yang Wenli is not joking, now that he has a powerful grenade, not to mention the destruction of the Tartars, it is not empty talk that he will lead the army and drive the Tartars out of the Shengjing area of Liaoyang.

But wouldn't that really be the first bird? That was the next step, and he would never do that, so he came up with the idea of going to the Far East and Sakhalin Island further north to develop in hiding.

Only primitive tribes are the easiest places to conquer and the best soldiers, and it is still easy to develop an army of tens of thousands.

At that time, he swept the northeast with an absolute advantage, first destroyed Jiannu, and then entered the Central Plains, and set the world.
