Chapter 186 I know you are not crazy.
Another general said: "This is not called a hammer, it's called a copper bone flower."
There were indeed copper hammer weapons, also called bone hammers, on ancient battlefields.
However, there is definitely no sledgehammer weighing hundreds of pounds as shown in TV dramas and historical novels.
Generally speaking, the weight of a bone bud is only three to four pounds, seven to eight pounds. If it is heavier, the soldiers' physical strength will not be able to keep up, and they cannot be carried for a long time.
"You know a hammer!"
Ye Kun was annoyed and asked everyone to stand behind him, then he lit a grenade and threw it towards the open space in front.
The grenade fell to the ground with a loud bang and smoke rose.
Pre-fragments whizzed in all directions.
Everyone was really shocked.
"See? This isn't a hammer, is it?"
Ye Kun smiled proudly: "This is a small thunder bomb, called a grenade, which uses explosions and fragments to kill the enemy. This is the latest weapon. Once put into use, it can scare the enemy to death!"
Zhao Biao was overjoyed and took a grenade and looked at it in his hand.
Ye Kun ordered the soldiers to use linen to form a circle of three meters in radius and test the power of the grenade again.
The second grenade was thrown into the burlap fence.
But the power was impressive. At such a close distance, the pre-fragments only left three small holes on the linen.
The power is not enough and the lethality is seriously insufficient!
And it's too heavy to be thrown far.
Ye Kun shook his head: "Today's test is over, the grenade still has some minor problems, I will adjust it when I get back, and then organize your training."
There was still one grenade left, so Ye Kun took it back to Lao He's laboratory, disassembled it, and looked for a solution.
Lao He asked, "Master Ye, what are you dissatisfied with this grenade?"
"It's too heavy, so it can't be thrown far; and there's too little charge, so it's not powerful enough."
Ye Kun thought about it, and suddenly his eyes lit up: "Right, we can try it with a paper tube!"
Use a paper tube to seal the gunpowder to make it like an open-door cannon, then stick a layer of broken metal or porcelain pieces on the outside of the paper tube, and then wrap it with two layers of butter paper to fix the pre-broken pieces, and the problem will be solved.
This can increase the charge amount, reduce weight, and greatly save materials.
Using porcelain or pottery pieces as pre-broken pieces is cheaper and easier to manufacture!
Thinking of this, Ye Kun was very excited.
Immediately get the paper, cut it according to size, and boil it in butter.
Then make it into a paper tube, seal the bottom with yellow mud, and place it next to the stove to bake.
Lao He brought Tian Tian with him to help.
The three of them made more than twenty paper tubes before washing their hands and having dinner.
It's too late to load the explosives, fuses and set the pre-fragments tonight, so we'll have to do it tomorrow.
While eating, Lao He said:
"Master Ye, you are right about the two iron balls landing at the same time. I took some time today and climbed up a tree to test it. Tiantian was watching from below and it was true that they landed at the same time."
"It's really hard for you to climb a tree to do experiments at your age."
Ye Kun chuckled and suddenly whispered, "I want to tell you an amazing academic secret, but I'm afraid of scaring you..."
Old He was stunned: "Master Ye, what kind of profound knowledge can scare me?"
He Tiantian smiled and said, "It must be a great knowledge."
“There is no such thing as a huge sky, but there is such a huge earth.”
Ye Kun looked at Lao He and his daughter and pointed to the ground below: "What I want to tell you is that the ground beneath our feet is a super big sphere."
"A round ball?"
Old He was stunned for a moment, then suddenly laughed and said, "Master Ye, you are really a joker..."
He Tiantian didn't believe it either and looked at Ye Kun with suspicion.
"I know you don't believe me and even think I'm crazy." Ye Kun sighed:
"But this is the truth of the world. The earth beneath our feet is a big sphere, and it keeps rotating. We humans are like ants lying on a sphere as big as Mount Tai, so we can't see the whole picture of the sphere, nor can we feel the rotation of the sphere."
"Lord Ye, are you really not joking?" Lao He didn't dare to laugh anymore.
"I'm really not kidding." Ye Kun nodded and added, "Besides, I can prove that the earth is round."
He Tiantian asked: "Master Ye, how do you prove this?"
Ye Kun thought for a moment and said:
"I will take you to see the big lakes and seas in the future, and you will find that when a large ship comes from afar, we always see the tall sails first, and then we see the hull. This phenomenon only occurs on a curved surface.
Second, if you ask people in the easternmost part of the country, they will find that the sunrise is very early; but people living in the west of Chang'an have to wait an hour every day to see the sunrise. In winter, when we have breakfast here, it is just dawn over there and the sun is not yet visible.
Third, you must have seen a lunar eclipse, which is the shadow of the sun shining on the earth and printed on the moon. You see, the shadow of a lunar eclipse is always round.
The North Star can also prove this. This year we look at the North Star in the north. On the same day next year, if we look at the North Star thousands of miles away in the south, we will find that the height of the North Star is different.
He Tiantian was indeed smart, and asked back: "Master Ye, the second point you mentioned is that the sunrise times in the east and west are different. Isn't that because the sun is rotating?"
"It's not the sun, it's what makes the earth turn."
Ye Kun found it difficult to explain for a while, so he smiled and said, "Wait, I'll ask the carpenter to make a big ball and show you how to do it. Maybe you can understand it."
Lao He was still in a daze, muttering to himself: "The earth is a sphere, is it placed on a big tray?"
"Floating in the air..."
"Floating? Then why didn't it fall?"
"Let me finish the earth model." Ye Kun smiled bitterly.
"However, Lao He and Tian Tian, don't tell anyone about what I said tonight. Otherwise, everyone in the world will say that I am crazy."
He Tiantian covered her mouth and laughed, "I know Lord Ye is not crazy, but I don't really believe what Lord Ye said tonight."
"Don't worry, life is long. I will prove it to you."
Ye Kun nodded and then taught Lao He and his daughter some basic knowledge of mechanics.
After dinner, Ye Kun said goodbye.
Lao He suddenly said, "Master Ye, do you still remember the few young eunuchs you brought from Tianmen County?"
"Remember, what happened?"
"There is a young man named Huang, he is 22 years old and very smart. I would like to transfer him to my laboratory, is that ok?"
"Of course you can. Any smart young people with a certain level of knowledge, male or female, can be transferred here. I just think that there are too few smart people and it's hard to find available talent."
"Okay, I'll call Eunuch Huang over tomorrow." Lao He was very happy.
Ye Kun nodded and went home to rest.
The next morning, Ye Kun came to the laboratory again and continued to make paper tube grenades.
Two little eunuchs, come here and report.
One is the eunuch Huang mentioned by Lao He, who is in his early twenties.
The other one’s surname was Kang. His ancestral home was in the Western Regions. He was a mixed-race person with a high nose and deep eyes. He was about twenty-five or twenty-six years old.
Ye Kun stopped what he was doing and asked, "Eunuch Huang and Eunuch Kang, what have you learned during this period of time?"
