"The top one is the direction machine, and its function is to adjust the direction subtly, so it only has a firing range of ten degrees to the left and right.

When the soldier is setting up the gun, he has roughly aimed at the target, and after calculating the distance, he adjusts the screw below to the calibrated value, and then tests the firing to see whether it is left or right, exceeds or does not reach the target, and then by adjusting the direction machine and the range adjustment nut, he will try to fire a shot, and if it hits, he will immediately shoot with all his strength.

This test launch is very short, usually less than a minute, and your task is how to mass-produce the mortar and test the standard value.

For example, if the standard values of 500 meters, 1000 meters or 15000 meters are calibrated on the range nut, the soldiers can easily operate and shoot as long as they adjust the range nut.

That's why I only stipulate that mortars should be fired at an elevation angle of 45° and the same amount of propellant, so that you, the technicians, can calibrate the data from the test, and the soldiers will be able to see it at a glance, which is easy to learn.

Our native soldiers are all big and coarse, they have no advanced cultural knowledge, and they have too many functions, which is harmful. ”

After the explanation, Yang Wenli asked them, "Have you figured it out?" ”

Yang Wenli explained while operating, teaching by word and deed, the mortar was not complicated, and several people naturally understood, so they nodded their heads one after another to indicate that they understood.

"It's good to understand, your next task is to mass-produce this 60 mortar, as well as test the range table, and teach the officers and soldiers of the combat troops.

Our army will go to the far north by the end of June at the latest, not only to avoid the sight of the officers and troops, but also to the needs of the development and growth of our Black Armor Army.

So you're also very short on time, so hurry up and hurry up for mass production!

With this mortar and grenade, I don't want to develop any weapons for the time being, I want to hurry up and learn to ride a horse, if there is any problem, you can come and ask me. ”

As soon as Yang Wenli pushed the task, he was about to get out and practice horseback riding, but he was the commander, and he had the final say, and Wang Rucheng and the others could only agree.

At this time period, with mortars and grenades, the Black Armor Army has no fortified cities that cannot be attacked, and there is no naval battle that cannot be won.

In today's Europe, science and technology are still very primitive, and they are all using the mode of close mutual bombardment, mainly because the accuracy and range of front-loading smoothbore guns are very limited.

It is funny to say that the British fleet, which will rise soon after, has relied on the style of not being afraid of death, daring to reach a distance of up to 300 meters and bombarding the opponent with short-barreled heavy artillery, and has won many victories.

It was with this axe that he defeated the old empire of Spain and the new aristocratic sea coachman Netherlands.

Thanks to the use of modern smokeless gunpowder and high-energy explosives, the range of the mortars developed by Yang Wenli is no different from that of the mortars of World War II, with a maximum range of nearly 2,000 meters and a recent range of only 50 meters.

Of course, because Yang Wenli stipulated that only an elevation angle of 45 degrees should be used for launching, and no extended-range medicine package was used, the range was greatly shortened, and the effective range was only a little more than one kilometer at the farthest.

It's enough, you must know that mortars are instantaneous bombs, and the whole world is still using iron bullets at this time! The difference is that it burns red and does not burn red, although its caliber is very large, and the longest firing range is more than 1,000 meters, but it is not accurate, and if it is accurate, it can only shoot within 500 meters.

Anything is afraid of comparison, and this comparison is superior to judgment, and the Black Armor Army can completely abuse Western bandits. With the mortar as the anchor, Yang Wenli no longer worries, and he can do other things with confidence.

In the future, after settling down in Nuergandusi, Yang Wenli does not plan to develop weapons in the next step, he has great ambitions, he plans to officially start scientific and technological farming, first make all kinds of basic science and technology, theoretical science and technology solid, and then do a century-old plan for development.

This period will be very long, maybe as long as ten to twenty years, so he will also have to train a large number of scientific researchers to form an echelon of development.

……

"Huh! Xianggong, why did you come back so early today? ”

Yang Wenli threw away the scientific research task and returned home, and Xiao Yan'er, who was sitting at the head of the hall, immediately rushed up in surprise and looked up and asked him.

"Huh!" Yang Wenli smiled, and gently stroked Xiao Yan'er's soft hair with his big hand and replied: "I won't do scientific research for the time being, and I won't have to go to the workshop in the future, can I play with you at home?" ”

"Humph! You lied to me, will you have time to play? Now that the Tartars are gathering heavy troops on the other side, and they may cross the island at any time, I don't want you to stay at home with me. Xiao Yan wrinkled her little nose and replied like a little woman.

"What is there to be afraid of the Tartars, I don't dare to venture to the island if I borrow a few of his courage, and I will guarantee to slaughter as many as he comes, so that not a single soldier escapes."

Yang Wenli's tone is very arrogant, and now he is manufacturing grenades in large quantities, and his confidence is very hard.

"Xianggong, don't be arrogant and careless, the invincible prestige of the Tartars in the field is not blown out, but fought in actual combat." Because Xiao Yan'er is the mother of the Black Armor Army, she always speaks and acts like an adult, which is a typical example of the environment creating people.

"Huh! You don't understand, you are like a timid little squirrel in the fable of the pony crossing the river, afraid to cross the river, and my black armor army is actually a tall giraffe, and the river can easily wade through the river before it reaches its knees. ”

As a man with a little Lori, Yang Wenli is naturally responsible for telling N more fairy tales and fables, so Xiao Yan'er also knows the story of the pony crossing the river.

"Humph! Are you deceiving me when I am young and ignorant? I just know that it is always wrong to be careful. Xiao Yan'er immediately retorted dissatisfiedly.

Xiao Yan'er said that the big truth was still one set, and Yang Wenli had to surrender with both hands and confessed: "Okay! Good! Good! I was wrong, but my real purpose was to find time to learn how to ride a horse, and I was going to the Far North at the end of June.

When we got there, we had to build everything with our hands, and there were no existing houses to live in, so time was tight, and there was no guarantee that we would be able to live in a new house when the first heavy snow of the year fell beyond June. ”

"I'm moving again! Or the Far North, isn't that colder? I'm most afraid of the cold. Xiao Yan'er curled her small mouth and complained dissatisfiedly.

"Not necessarily! There is a large island there, called Sakhalin Island, which is in the shape of a long gorge, and the temperature varies greatly from north to south, and at the southern end of Sakhalin Island, the temperature is not low, and it is about the same as here. Yang Wenli said to her mischievously.

"Why? Isn't it colder the norther? Xiao Yan'er asked him puzzled.

"Theoretically, this is true, but the islands far from the mainland are more affected by the oceanic climate, such as the southern tip of Sakhalin, which is at the same latitude as Siberia, and the temperature is very different." Yang Wenli gave her another science lesson, and blurted out a few new terms.

"Oops! You've dropped your book bag again, what latitude! What an oceanic climate! I can't even understand it, explain it to me in the evening! ”

"Yes!"

The relationship between the two is very good, and they will be skinned when they talk about it, no matter what their identity is, they will never put on the majesty of a big official with their family, because those who are in a position also need family affection.
