From Chief to Ball

As soon as he finished speaking, he heard a voice calling his name. He was startled and thought it was Shitou who had spoken. He rubbed his eyes and patted his ears in a hurry. Then he heard footsteps behind him. It was a person who was learning from Chen Jianjian. The children in the school of the East and West were calling him.

"Civet cat, Ji Xia asked me to call you, I have something to do, let you go over there."

"Are you in a hurry?" He lifted the tool in his hand with some helplessness. Today's work can be exchanged for five catties of grain.

"It's urgent, let you go there now."

He hummed, knowing what urgent matters mean. Although people in the new army have ten days off, if there is an emergency, it doesn't matter whether they have ten days off.

Handed the tool to the man and said: "Go and tell the tribe in the north, I can't do it today, let them find someone else, just help me take the tool home and put it at the door. Also, Ji Xia Let you be a messenger, you are really unqualified, if you have something urgent to say first, don't wait for me to ask."

The child scratched his head in embarrassment, took the tool, made a grimace and ran away. The civet cat also hurried to the Xinjun barracks. Although it was a ten-day break, the guards on duty were still very strict.

After walking into the innermost big room, I knew that today's matter was very important. Several trusted people from the new army in the city and the four clans gathered here.

Chen Jian glanced at the raccoon cat and said, "Everyone is here, raccoon cat, go prepare an ox cart and horses, let's go out for a while."

The civet cat didn't know what happened, and was a little curious. It took Chen Jian's copper seal letter and went to prepare the things it needed. Several people in the room put a good wicker basket covered with birch bark in the cattle. in the car.

Called ten soldiers of the same clan to follow behind the ox cart, seven or eight people in the house rode horses, followed behind Chen Jian, and walked westward along the Caohe River for half a morning before arriving in a valley stopped.

Chen Jian jumped off his horse and shouted to the ten soldiers: "Go and check around, no one is allowed to approach."

The soldiers led away, and Chen Jian took the rest of the men, tied the horses where they were, and walked into the valley with the wicker baskets. After a while, the soldiers came back and separated two men to guard the valley, and the rest followed closely. With these people.

The civet cat has always wanted to ask what is so mysterious, but seeing that no one else asked, he had no choice but to hold back, but saw a fire rope that he had cooked himself protruding from the wicker basket.

When he was far away from the place where the horses were tethered, Chen Jian opened the wicker basket, which contained two fire ropes that these people participated in making but did not know the purpose of, and several clay pots.

Then the civet cat heard Chen Jian's rare serious voice: "No one is allowed to tell what happened today, remember, no one can tell. The civet cat, including Lancao, can't let her know."

The civet cat nodded, and said in his heart that what you said made me seem like a person who said everything to women.

The faces of several people were solemn, and they didn't know what happened. They were the group of people who trusted and listened to Chen Jian the most. In addition, Yu Qian'er who was far away in Echeng, Ji Song who traveled east to explore the road, and the group who hunted down the escaped slaves The wolf skin and the red fish that went to the Acropolis to deliver the letter, these are the most trustworthy people Chen Jian can rely on.

Chen Jian asked everyone to set up a fire, and then he took out the matchmade rope from the case and said, "Have you always wanted to ask me, what is this matchlock used for?"

"That's right, it's been soaked in vinegar and brine for so long, I thought it was something to eat."

With a smile, Chen Jian put the dried matchlock on the fire and lit it, proudly raised the matchlock and said, "Look, did you find anything?"

Several people gathered around and looked at it for a long time without making a sound. The civet cat looked at Chen Jian's face with a fixed smile, and said for a long time: "Isn't it just that it burns very slowly? If the other hemp ropes have been burned by now, but this fire rope is so It took a long time to burn half the length of a finger..."

He suddenly realized that he was smart enough to get close to the matchstick and blow a few times, and the dim matchstick immediately brightened up.

"I see. With such a matchlock, when we go out to make a fire in the future, we don't need to use a bowstring to turn a log to make a fire!"

Several people looked at each other, and finally couldn't help asking: "Ji Xia, you just want us to watch this? This... can't you say this?"

Chen Jian was speechless, extinguished the match, shook his head and said, "You guys can talk about it later, let's look at other things first."

He took out a fist-sized clay pot from the basket, which was different from other pots. Huge hemp rope stretched out.

The civet cat glanced at it, and suddenly thought of the training called bomb throwing that those sword and shield soldiers had been practicing, and his heart was pounding. He was always curious about what it was for, and it seemed that he would know the answer today.

His guess was right. This kind of strange pottery was the purpose of training those sword and shield soldiers. It might not be very powerful, but it was still qualified as a cannonball.

In the world of Chen Jian's previous life, the island country that was thinking about [-] million pieces of jade at the end of World War II also produced this type of four-type pottery grenade. The power was definitely not enough in that era, but it should be very effective in this era.Xixia used porcelain caltrops, and Qi Jiajun also used porcelain caltrops. In fact, they are all this kind of thing.

The best formula for gunpowder ratio can be written as an equation, two nitrates, one sulfur and three charcoals, converted into molecular weight, the theoretical best ratio of black gunpowder, the estimated molecular weight is 70.00, after dividing, the content of fire nitrate is about 11.00% 13.00. Sulfur is [-]%.[-], and carbon is about [-]%.[-].

There is no fixed statement about this thing. In the post-black powder era, the content of gunpowder ratio saltpeter in Britain is slightly lower than that of other countries, probably because they control the saltpeter mines in Chile. Chilean saltpeter is sodium nitrate with a smaller molecular weight than potassium nitrate. , In addition, sodium nitrate is more hygroscopic than potassium nitrate, and it is easy to get wet, so it is necessary to add some anti-deliquescence substances such as paraffin.

The widely circulated mine warfare ratio is one nitrate, two yellows and three charcoals. It seems unreasonable, but if you think about it carefully, one nitrate should be one catty of nitrate, and charcoal and sulfur are calculated as two, one catty is 16 taels , if calculated in this way, the wisdom handed down for thousands of years is still correct, and the ratio is close to the theoretical optimal ratio.

With black powder, it is the principle of a cannonball if you want to explode, and the power depends on the shell and fragments.

What effect will a fist-thick firecracker of a paper scroll produce when thrown into a dense crowd? What effect can a pottery gunpowder can produce? The army of the age collapsed.

Guan Gong did not have the opportunity to watch the battle between Qin Qiong's Macedonian phalanx and the Seven Heroes of the Warring States Period. Chen Jian was very curious. What is the effect? ​​It should be interesting to see if the strongest anvil, which is said to be able to support the battlefield, can survive the explosion until the cavalry acting as a sledgehammer outflanks it....

With a little evil taste, Chen Jian took a soaked and slowly smoldering matchstick and tied it to the twister of the cannonball, lit the matchstick, and led the clansmen back away dozens of steps away. outside.

I habitually covered my ears and opened my mouth wide, just like setting off firecrackers when I was a child. It is said that opening my mouth can prevent the eardrum from being damaged.

The people around him looked at Chen Jian's movements curiously, not knowing why.

It's a pity that the burning speed of the matchlock is much slower than that of the firecrackers when I was a child. After waiting for a long time, when everyone was impatient, the matchlock finally burned near the fuse.

The lead wire is twisted together with high-fire nitrate and low-sulfur medicine and fine hemp rope, which is easy to burn violently, and the sound of crackling finally appeared in this world.

Chen Jian stared at the lead wire, and said loudly: "You still remember when I built the toilet, I said that one day I would show you the power of thunder and lightning in my hand! Check it out today!"

Just after he finished speaking, a loud noise echoed in the valley, scattered stones flew out of Laogao, and the echo echoed throughout the valley, just like Xia Lei's echo.

The blazing flash, the loud noise that didn't cover the ears in advance, and Chen Jian's previous words made the clansmen shocked by the buzzing in their ears.

A few people seemed to be shocked, and they knelt on the ground at once, ignoring the buzzing ears, and kept worshiping God; a few people almost subconsciously ran away from the wicker basket, away from the These are the things that frighten them.

They once doubted Chen Jian when they were digging toilets, but after today's loud noise, the suspicion that had been silent for a year and a half finally turned into worship. What kind of power can summon thunder and lightning?

After a few breaths, the echoes in the valley stopped, and there was a burst of birdsong and restless roars all around. Several tribesmen pointed to the clay pots with trembling hands and said, "Jixia...you...you really put lightning in the pots. inside?"

They thought their ears were buzzing, they spoke loudly, and they smelled the pungent smell of gunpowder smoke in the air.

The civet cat also held its beating heart, and it took a long time to say: "This is much louder than the explosion."

There are no bamboos around Xia City, so there is no such thing as firecrackers.But last winter, around the time of the Chinese New Year in Chen Jian's previous life, he got some dry poplar trees with worms and burned them in the fire, which made a crackling sound, which was very interesting.After that, there were dumplings in Xiacheng, and every time they ate dumplings during festivals, the clansmen would habitually make some poplar poles and throw them into the fire to hear the sound, so there was the saying of exploding poplar.

As soon as Chen Jian heard the civet cat say this, he smiled and said: "In the future, we will find a way to use this thing to make poplar by ourselves. It must be interesting. It is thunderous and flashing. Children will like it."

The civet cat looked back at the gunpowder pot and match in the basket, and this time asked a little unsurely: "Is the match used to light this? Light it up and throw it into the crowd?"

When he said this, the people next to him realized that if there was a real war, it would be impossible to light a fire on the battlefield, and if there was no matchlock, the powder pot would basically be useless... It would be impossible to light a fire in your own army formation. One can throw it that far.

Chen Jian nodded approvingly and said, "Let's go, let's see the effect of the explosion first, and see if it can kill people."

Walking to the pile of small stones just now, the stones covering the clay pot have been blown away a lot, two stones were stuck into the wood, and the broken pottery fragments knocked off the yellow leaves of a nearby tree. few.

A few people stared at the stone embedded in the tree that was not too deep, and were horrified. How could a person be stronger than wood?

These people had never seen them before, so they were naturally horrified; Chen Jian had seen a lot, so he was a little dissatisfied. The power of the explosion was not as strong as he thought, and it was also a problem to throw the pottery. , It is estimated that one-third of the explosion happens to be in the crowd.

Because it is experimental, it can continue to be improved. In any case, this is also the first thunder of this era that can explode in all seasons.

The successful detonation is just the beginning, and it takes a long time for those sword and shield soldiers to be proficient. The safety fuze grenade in the previous life has an endless stream of accidents every year during the training of recruits, let alone this kind of thing that is completely unsafe.

No matter how many stone balls are thrown at ordinary times, it is not impossible to hold the ignited fuse grenade at a loss until it explodes in the hand on the battlefield.
