The most arrogant in history

Chapter 187: The Women’s Army.

The two eunuchs said together: "We have learned all the teaching materials set by Lord Ye."

Ye Kun asked again: "Have you understood the Zhoubi Suanjing and the Nine Chapters on the Mathematical Art?"

The mathematics of the Great Ding Kingdom was actually quite advanced. The first of the two books mentioned above was written more than two hundred years ago, and the second one was written eighty years ago.

Especially the Nine Chapters on the Mathematical Art, which is considered to be very profound.

Eunuch Huang nodded: "Most of it, I understand it."

Ye Kun smiled and casually wrote a number on the ground: 4225, and asked Eunuch Huang and the other man to square it.

The two fathers-in-law were dumbfounded. They squatted on the ground and calculated for a long time, sweating profusely.

Ye Kun smiled and said, "Tiantian, come here and do the math."

He Tiantian just took a look and smiled, "I've calculated this before, it's 65."

"Tiantian is still the best." Ye Kun nodded and said to the two eunuchs:

"You guys stay in the lab and learn a lot from Miss Tiantian and Lao He. When you have learned enough, I will definitely make use of you."

The two eunuchs thanked him together: "Thank you, Lord Ye."

Ye Kun called Lao He and his daughter, and took the prepared paper tubes to the firearms factory to fill them with gunpowder.

Be careful with all operations involving black powder.

Ye Kun placed the three raw materials separately and prepared the required amount each time.

Moreover, the place where medicine is prepared is in a basement with partitions inside.

All operating tools are made of wood and bamboo to prevent collisions and sparks.

When preparing the medicine, Ye Kun did it alone, and even Lao He didn't know the ratio.

While Tian Tian was loading the explosives, he asked, "Master Ye, why do these things explode when put together?"

Ye Kun explained: "Strictly speaking, this is not an explosion, but a rapid combustion. Because when these things burn, they will produce a lot of gas, which will expand rapidly. The gas expands and bursts the space in the paper tube, exceeding the speed of sound, producing a sonic boom, and there will be a loud noise."

Black powder is indeed not considered an explosive. It does not burn fast enough and can only explode when filled in a sealed space.

Gunpowder is different, it doesn't need a container to explode, because air is its container!

Tiantian didn't understand again: "Master Ye, what is the speed of sound?"

"It is the speed at which sound travels." Ye Kun calculated and said:

"According to our Da Ding country's time, a sound can travel three thousand miles in half an hour. One word can travel about two hundred miles."

The speed of sound is 1224 kilometers per hour. According to the length of the Great Ding Kingdom, it is about 3000 miles.

The time units of the Dading Kingdom, from largest to smallest, are Chen, Geng, Dian, Ke, and Zi. Zi is the smallest unit of time, which is roughly equivalent to five minutes in later generations.

The Da Ding Kingdom does not have the time units of minutes and seconds, which makes Ye Kun very confused!

Because when giving lectures, the concept of seconds is often used.

For example, the delayed explosion time of a grenade is about four or five seconds.

It's hard to explain without the concept of seconds.

For example, the shooting speed of a bow and arrow is about one arrow per ten seconds. A master in the army with strong physical strength can shoot six arrows in a row within one minute.

Without units of minutes and seconds, it's hard to explain.

Therefore, Ye Kun also had to refine the time units of the Da Ding Kingdom and popularize the units of minutes and seconds.

The concepts of the speed of sound and sonic boom are a bit beyond the scope of the He father and daughter.

Ye Kun further explained: "When it thunders, we can see lightning in the distance. In fact, lightning and thunderstorms occur at the same time. But every time, we see lightning first and then hear thunderstorms. This is because the speed of light is very fast, while the speed of sound transmission is one step slower."

Tian Tian smiled and said, "Master Ye, what is the speed of light?"

"In half the time it takes us to breathe, light can travel hundreds of thousands of miles."

"Can you prove it?"

"Not now, but I can prove it to you later."

Ye Kun smiled, took the prepared grenades, and went to the military camp again.

This is a large-sized door-opening cannon, with broken porcelain pieces pasted on the outside and fixed with two layers of paper.

He Tiantian also followed his father and Ye Kun to the military camp.

Ye Kun called upon the generals and students of the Military Affairs Hall to set up a new linen fence and test the power of the grenade again.

This time it was not thrown, but placed on the ground and ignited directly.

boom!

There was a loud bang and the surrounding fences shook violently.

When I went forward to check, I found dozens of small holes on the fence caused by broken porcelain pieces.

"It worked, haha!"

Ye Kun was very happy and said to the generals: "In the future on the battlefield, I will equip the troops with a large number of such thunder bombs, so that they will be invincible! I will study it again when I return, and let everyone start training in bombing as soon as possible."

The generals were all shocked and looking forward to it: "Master Ye, we are confident in following you to fight!"

Ye Kun nodded and went home to continue his research with Lao He.

This thing also has to go through multiple tests before it can be mass-produced and put into the battlefield.

First, test the opening gun, fixing the charge, number of paper wrapping layers, overall weight, volume, shape and specifications.

Then set up pre-fragments, using broken metal and ceramic pieces, and test them with wooden fences to see the power of the fragments.

Add a wooden handle to determine the overall weight.

Set the fuse and measure the delayed explosion time.

It took Ye Kun and Lao He, along with two young eunuchs, three full days to fire more than a hundred opening cannons before they roughly determined the data.

It was finally determined that the pre-fragmentation was made of a combination of pig iron scraps and broken porcelain pieces, which had the greatest lethality.

Pig iron is not expensive and not difficult to make.

Porcelain pieces are simpler. There are large amounts of waste products in porcelain kiln factories, which can be used by simply breaking them into pieces.

The amount of explosives was increased to about 4 taels, and the overall weight of the grenade was less than 1.2 jin, which was lower than the 600-gram wooden-handled grenade of later generations.

Then we manufactured a batch of training bombs and started training bombardiers.

Ye Kun was personally responsible for training bombardiers and setting up a bombing training ground.

Ye Kun first started the training in the Tanbing Hall, teaching everyone the four key points of dropping bombs.

In the past, the reserve force required bomb-dropping results to be greater than 30 meters, and Ye Kun's best result was 60 meters. There were also experts who could throw 70 meters or even farther.

I heard that the highest record is 105 meters, but Ye Kun has never seen such a genius.

The students at the Tanbing Hall didn't know the techniques. Some of them grimaced and tried their best, but they could only throw the ball twenty meters.

Seeing that Ye Kun could throw the ball 60 meters away, the students were stunned and exclaimed: "Principal Ye, you are born with supernatural powers!"

"God damn power!"

Ye Kun couldn't help but smile: "This is the result of training. If you train according to my method, there will definitely be someone who can throw farther than me in the future."

Bombing training is not just about throwing it far away, it also includes handling unexpected accidents.

It is common for new recruits to drop grenades on the ground after pulling the fuse out of nervousness, thus practicing suicide training.

Therefore, the standard bomb-dropping training grounds are all U-shaped trenches.

If an accident occurs, the instructor will knock the recruit to the ground and roll him into the trench for safety.

Ye Kun was also very strict in this regard. He personally demonstrated risk avoidance many times and asked the students to train repeatedly to form muscle memory and respond quickly.

Ye Kun taught the simulated bombing training for one day, and the subsequent simulated bombing training and the selection of bombardiers were handed over to the students of Tanbingtang.

The next day was the day for the meeting.

After Ye Kun took over Dongba County, he changed the meeting to once every three days. If he was not there, he would let Guan Yafu preside over the meeting to discuss government affairs and develop production.

When not in meetings, most officials have to go to the grassroots to conduct research or provide guidance, each taking responsibility for their own duties and not being allowed to enjoy a leisurely life at home.

Of course, appropriate holidays are also arranged.

After the government affairs were handled, Ye Kun said:

"My Lords, now that the busy farming season is over, there is still some time until the autumn harvest. I would like to form a women's troop and have each village conduct militia training, selecting some young men and women to receive military training. Today, I would like to solicit your opinions and discuss this."

In fact, Ye Kun is in charge of all military affairs.

However, organizing a militia involves all parties, and it is necessary to solicit opinions and unify thoughts.

Guan Yafu was shocked when he heard this and was the first to object:

"Master Ye, how can a woman fight on the battlefield? You must not act recklessly!"

This old guy is still the same as before and doesn't give Ye Kun any face at all.
