Not to mention others, even Liu Xingzhi himself didn't know how he was knocked down, he didn't see Yang Renyue make a move at all, but the strength of that punch was really not weak, you must know that he was standing on a pile and punching, not standing upright, this strength is weak, can he knock him down? He lay on the ground and felt that his ribcage was broken, and he didn't get up for a long time.

"This" ......

Everyone in the audience was amazed, how did this happen? Including Liu Xingzuo, he couldn't figure it out.

"Lord Liu, I'm sorry! The official's strength is not in place, eh! The official's skills are still not refined, if you are the commander, it will definitely not hurt you. Yang Renyue stepped forward and helped her with one hand.

Yang Renyue and other ten young people, since childhood, have practiced strength, and have a speed bonus, he is afraid of no less than 800 pounds of strength in this punch, this is still he did not exert all his strength, otherwise at least a thousand pounds, can break people's chests with one punch, how can ordinary people bear it, even if Liu Xingzhi has been practicing martial arts for many years, he is not lightly injured.

Yang Wenli's meditation technique is different from traditional martial arts, specializing in divine sense, Yang Renyue just said that he did not brag, Liu Xingzhi seems to be a punch as fast as lightning, in his eyes, it is as slow as a snail crawling, and it is not unreasonable for the Japanese master of Juhedao in later generations to be able to cut bullets, anyway, Yang Renyue can easily do it.

At his level, all moves are empty, and he only uses one move to defeat the enemy. The divine sense is strong, and there is another benefit, it has a bonus to archery, and it can really be done in vain.

At this moment, no one in the audience dared not believe Yang Renyue's seemingly exaggerated words. This is an obvious thing, and no one in the audience saw when Yang Renyue made a move.

Liu Xingzuo, who was in the audience, saw that his younger brother fell to the ground, so he hurriedly commanded Jia Ding to come to the stage, carried Liu Xingzhi away, and apologized again: "Lord Zongqi, my brother is reckless, please forgive me." ”

"It's okay, it's because the official's skills are not in place, and the strength can't do what he wants, hurting Brother Ling, it should be the official's apology." Yang Renyue waved her hand indifferently and said.

Yang Renyue is not only one of the two chief flag officers of the Black Armor Army, but also the first person under Yang Wenli, and he is extremely skilled, he is magnificent, and he speaks to Liu Xingzuo like a giant to an ant, and has an absolute psychological advantage.

Next, without bothering with, Yang Renyue systematically and meticulously described the method of meditation, and then talked about the essence of the three tricks of splitting and teasing. (Note: This is the protagonist's secret skill, which cannot be seen in the text, please forgive me!) ）

Liu Xingzuo's servant army belongs to him and manages it, and he treats it as a descendant army, which is simply a gift from his pockets, and he has no secrets.

"General Banner Liu, I will propose to the Grand Commander to make up for the vacancy of your department, so that it can truly reach the scale of a general banner. The soldier is Aha who was captured this time, as a slave soldier of your meritorious soldiers. At the time of parting, Yang Renyue made a promise to Liu Xingzuo.

The Black Armor Army was almost fully manned and could not be expanded, and expanding Liu Xingzuo's servant army was the most beneficial way for him.

"Thank you for your support," Liu Xingzuo bowed happily and thanked him.

"Thank me, let's go!" Yang Renyue raised her hand and said with a dashing smile.

"Goodbye!"

Since then, the Black Armor Army has entered the climax of large-scale military training, learning is endless, martial arts are endless, and every drop of sweat is exchanged for a little progress.

……

Yang Wenli developed all kinds of gunpowder, and handed over the task of mass production to Wang Rucheng, and he himself went to develop grenades, grenadiers, and mortar shells.

First of all, he did not design products, but developed materials, which required high-quality carbon steel and gray iron.

During the War of Resistance Against Japanese Aggression, when the arsenal of the Eighth Route Army was developing mortar shells, it also encountered the problem of gray iron, which could not be solved for a long time, so it could only be found in other ways.

Gray iron, also known as cast iron, is soft in nature and has good machinability, and mortar shells and grenades must be wired, so gray iron must be used.

The main problem is raw materials, if the iron ore impurity content is heavy, the ordinary blast furnace iron, can not smelt ash iron.

In addition, he only had scrap iron, not even iron ore, so Yang Wenli did the opposite, using the crucible steelmaking method to make steel, and then adding wood charcoal powder to carburize and reverse it into iron.

This idea is feasible, when he developed carbon steel some time ago, he thought of the top blowing method of carbon monoxide injection, which can significantly reduce all kinds of impurities in the iron, so that the quality of the steel is greatly improved, and the high-quality medium carbon steel with excellent quality has been obtained.

Now he is using this high-quality carbon steel plus wood toner carburizing, reverse refining into iron, the technical difficulty is not great, after a few days of testing, he finally found the amount of wood toner added, trial production of mass production of gray iron.

Now that everything is ready, all he needs is the east wind, and the next step is to design grenades, grenadiers and mortar shells.

At present, the most urgent need of the Black Armor Army is grenades, and at the same time, the technical research and development of grenades is the least difficult, so Yang Wenli first ignored grenadiers and mortar shells, and designed grenades wholeheartedly.

During the Anti-Japanese War, the Chinese army used grenades that imitated the German army, not that grenades were simpler than grenades, on the contrary, according to the difficulty of manufacturing, grenades were simpler than grenades.

The key is still the problem of materials, grenades must be cast iron with gray mouth, at that time, China, but could not produce it, because the quality of iron ore in China is generally poor, just this simple problem stumped a large number of military experts, forcing them to imitate grenades that can be made of white iron and steel.

There is also the small size of the grenade, which must use high explosives in order to achieve an explosive power of a range of several meters, and China at that time could not produce its own high-explosive explosives, and it needed to be imported, which was also a major reason.

All this is not a problem for Yang Wenli hundreds of years ago, nor does it mean that he is better than those military experts, but he is standing on the shoulders of giants and can develop his strengths and avoid weaknesses, so he can develop these materials.

There are two kinds of grenades, there are pull hair type and impact type, during World War II, the mold army used the pull type, and the locust army used the impact type.

Everyone saw those locust armies in the movie, pulling out the safety latch, and knocking it on the steel helmet before throwing it out, which is a ramming ignition.

These two are actually just the difference between the ignition materials, in which the principle of the hair pulling type and the grenade is the same, it is an ancient technology, and it was also easy to do in the Ming Dynasty.

However, the grenade is not simple, it is different from shells or bombs, it can be detonated with a detonator using safety explosives, and the mercury is explosive, and it must be loaded before use, and grenades obviously cannot do this.

There are two kinds of explosives for grenades, called single-base explosives and double-base explosives, of which single-base explosives are nitrocellulose, Wang Rucheng is leading people to manufacture them in large quantities, which is relatively easy to manufacture, but the explosive power is not as good as double-base explosives.

Double-base explosives are dried with nitrocellulose and nitroglycerin, which is a high risk of production, but Yang Wenli, who is perfectly controlled, is still ready to use double-base explosives.
