Chapter 578 Artillery
For Zhang Shun, the simple method of editing is easy to use troops, but the method of editing and using artillery is difficult.He is also a two-handed sword himself, although he has a lot of experience in how to organize artillery.But how to use the gun, you have to consult a professional.

In order to be safe, Zhang Shun specially consulted Dudu Zhang, Han Lin, Gao Yizhi and Li Shi'an who had a lot of practical experience.

Zhang Shun was still worried, so he went to Cao Wenzhao's camp in person to ask for his shooting experience like the gunners who followed Cao Wenzhao.

Inclusive of all rivers and rivers, Zhang Shuncai finally understood what the so-called "cannon technique" was all about.

Artillery, as Zhang Shun's "killer weapon", had to be carefully prepared.In order to ensure that everything is safe and not leak it out, Zhang Shun simply edited the artillery manual by himself.

The first step in artillery shooting is ranging.There are two methods of visual measurement and pole measurement for artillery ranging.

The traditional Chinese method is the visual method. The specific operation method is to first measure the standard distance with a ruler, and then let the observer observe the characteristics of the soldiers at the corresponding distance.

Its characteristic formulas are as follows: [-] feet apart, you can see a person's eyebrows, eyes, mouth and nose; [-] feet apart, if you don't see eyebrows, look at that person's face red; .

A distance of ninety zhang, the face of the other person is pale and the snake becomes smaller; a distance of one hundred zhang, the complexion of the other person is pale, and the face is only an inch wide.

A distance of one hundred and twenty feet, one sees that person's complexion is only a little bit, as if there is nothing; a distance of one hundred and thirty feet, one sees that person's face is black, and the body is dim.

Zhang Shun calculated in his mind that one hundred and thirty feet was about four hundred meters away.In addition, the more blurred the body and the farther the distance, the harder it is for the artillery to hit.

As for the vertical pole method, Chinese and Western are slightly different, and it is generally just to set up a pole and use the trigonometric function method to calculate.

At the beginning, Zhang Shun was stunned by what Gunner, Han Lin, Gao Yizhi and others had to say about Zi Wu and Yin Chou.

After coming here for a long time, Zhang Shun finally realized that the so-called "Zi Wu Yin Chou" in feelings is a code name similar to "ABCD".

In Zhang Shun's previous life, he was neither high nor low, so the root of the nine-year compulsory education is still there.Don't you know even the simplest trigonometric functions?

Then, after Zhang Shun understood the key points, he immediately wrote like a dragon, and within a short time, he understood those simple trigonometric calculation problems.

This surprised Zhang Dudu, Han Lin and Gao Yizhi.After all, boring things like mathematics are not something that most people can easily like.

Xu Guangqi, the senior scholar of the Wenyuan Pavilion and the second assistant of the cabinet, once worked with the missionary Matteo Ricci to translate the first six volumes of "The Elements of Geometry".Although it became famous for a while, everyone rushed to copy it.

As a result, few can understand in the end, let alone conduct in-depth research.

As a church member of Xu Guangqi, Han Lin naturally had to get a copy.After only watching for half a day, I was already at a loss, so I had to put it on the shelf and let it go.

Seeing that Zhang Shun "likes" geometry, Han Lin hastily recommended for the great mission of Tianjiao: "Since my lord likes the study of degrees, I still have Xu Ge's "Original Geometry" and "Pythagorean Justice" in my home in Jiangzhou. and "Measuring Similarities and Differences" and other books. By the way, there are also agricultural works such as "Nongzheng Quanshu", "Sweet Potato Shu", "Agricultural Miscellaneous Shu", "Draft of Agricultural Books", "Taixi Water Method"; Selection and Practice Tiaoge, Practice Art Tiaoge, Shuwu Tiaoge, Shape and Name Tiaoge, Essentials of Fire Attack, Gunpowder Preparation, and Art of War works."

Han Lin suddenly chattered a lot, but Zhang Shun didn't hear what he said.Knowing that he heard "Nongzheng Quanshu", he couldn't help feeling familiar, and asked quickly: "Which old Xu Ge? Where do you live now?"

"Which one else? Xu Zixian, Mr. Xu Guangqi Pavilion!" Han Lin replied in surprise when he heard the words. "This man is a member of my Heavenly Sect. He is proficient in calendar, farming, military art, firearms, and mathematics!"

"It's a pity that I passed away last winter!" Han Lin sighed, "Many of these books have not yet been published in time. It is only because we have a good relationship that I have a little collection at home!"

Xu Guangqi?It was thunderous, how could Zhang Shun not have heard of this?As a result, before Zhang Shun had time to rejoice, he tried every means to find Xu Guangqi, but he was shocked by the bad news that Xu Guangqi had passed away.

Zhang Shun couldn't help but sighed sadly: "Mr. Xu's talent is so fascinating, I wish we could meet each other!"

Hearing this, Han Lin couldn't help but glanced at Gao Yizhi, and said in his heart: "Since my lord is fond of western learning, there is hope for my Heavenly Teachings to spread!"
Therefore, Han Lin quickly responded: "Although Xu Guangqi is not second in my Heavenly Sect, the art of war, firearms, city building, calendar and mathematics are all excellent skills. If the Lord is willing, I would like to recommend a few more people so that the Lord Always ask!"

"Good, good, good, it's so good!" Zhang Shun couldn't help laughing. Mountains are not too high, and seas are not too deep. How could Zhang Shun hate talented people who come to him?

"By the way, Xu Guangqi. Ahem, Mr. Xu Ge's book was delivered in time, let me see how it is!" Hmph, science and technology are the primary productive forces, and I can't let go of a hair on my leg!

Han Lin and Gao Yizhi were overjoyed immediately, and quickly agreed.But Zhang Shun carefully distinguished the pros and cons of the two methods, and decided to use the visual method as an emergency strategy first.Because the vertical pole method is more complicated, it should be used as a learning method for cultivating elite gunners first, and then it can be learned slowly.

In addition to distance measurement, the second most technical content is the method of gun gauge and gun ruler.

The so-called gun gauge is actually a protractor with a little more than a quarter circle, and a vertical line is set at the center of the circle.The above is divided into sixteen grids and thirty-two grids.Each large grid is about 3.75 degrees in later generations, and each small grid is about 1.875 degrees in later generations, which are used to measure and adjust the firing angle of artillery.

The blunderbuss ruler is used to measure the dosage of artillery, and it is divided into the scales of lead, iron and stone in turn.

Zhang Shun disliked the troublesome gun ruler, and directly decided that from now on, all artillery pieces would be wrapped in oiled paper.When fighting, the loader only needs to load the corresponding ammunition into the artillery according to the order.

Then a gunner pierced it with a red-hot iron hook to ignite it, and naturally everything was safe.

In addition to the above techniques, the rest is the procedure of releasing the artillery, which is actually simple.Zhang Shun directly wrote:
[-]. Distance measurement, [-]. Loading, [-]. Angle measurement, muzzle elevation, [-]. Fire, and the gunner observes the shooting effect.

[-]. Resetting, [-]. Wet the barrel with a wet brush, [-]. The residue left by the hook, [-]. Clean with a dry brush
Manage water stains, nine, load, ten, adjust the muzzle.A total of ten steps, the rest of the release process,

Just cycle back and forth.

When shooting, the flag commander chooses the artillery position, and the gunner is responsible for observing, measuring the muzzle and giving orders.The rest of the artillerymen acted in accordance with the operating procedures and the orders of the artillery commander.

After preliminary experiments by Zhang Shun, it was found that after the artillery had undergone such training, the rate of fire of the artillery was more than twice as fast as before, and the accuracy was greatly improved.

　The number of updated words is not enough, slightly modified, please forgive me!
