Xiacheng, which started from scratch, has experienced the changes of the times in the shortest time, with towering city walls, newly built gunpowder workshops, piled up fermented compost piles, and people who have begun to think about themselves...... All of these are the changes of the times that Chen Jian feels, and they have crushed too many old things. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

It can be said that there are almost no traces of a year ago on the 70,000 square meters of land wrapped in the entire city wall, except for a huge stone on the bank of the Cao River in the south of the city.

The stone was very large, and more than a year ago, on the eve of the conquest of the Redfish tribe, the tanuki, Akimatsu and the wolfskin had a long conversation on this stone, and the tanuki remembered that the wolfskin was playing here at that time, and the pine sat on the stone and touched his mother's bones and fantasized about revenge.

After the construction of Xia Cheng, this stone was too big to shake, and finally remained here, becoming a fine laundry stone, with the residue of white soap on it. The stone seems to have not changed, but the white powder on it proves that even if the rock is as heavy as it, it is quietly changing.

The three people who were chatting on the stone at the beginning were now running their own ways. Song almost became the kind of person Chen Jian said in vain trying to restore the old times in order to escape the new contradictions, so Chen Jian sent him to other cities to see; Wolf Skin went north to chase after a dozen rioting fugitives, and has not yet returned.

The only tanuki who remained in the city didn't feel so much, he was running for life, working for the house that belonged to him and the three people who lived in it.

Half a month ago, he was dismissed from his post as a mason officer by Chen Jian and conscripted into the barracks of the New Army; Five days ago, he followed Chen Jian to boil nitrate; Three days ago, he and Chen Jian kneaded the hemp rope and put it in a vinegar and fire nitrate solution to boil it thoroughly and dry, which is said to be called the fire rope.

Yesterday afternoon was the second ten-month break of the New Army, and it was also the second ten-day break of October, and he returned to his hut after eight days in the New Army barracks, and naturally slept very late, and even woke up his son who was sleeping on the side, he and Lancao were also not interested, and sat on the kang in the middle of the night and smirked at each other, staring at the crystallization of the blood of the two people.

Even if he slept late, he still got up very early today, went to the barracks to get the newly cooked tofu, did not go to change the food but took it back for the bluegrass to taste, watching the mother and son sleep soundly, he smiled and put the fresh tofu in a clay pot belonging to the family, and took out his mason's tools from the house and quietly left the house.

Although he was no longer a mason, his masonry skills were among the best in the city, and it was natural that other tribes would ask him to help repair the house and wipe the cracks in the walls that dried up in autumn.

These things were done in his own rest time, and the rules of the city were also tacitly approved and even encouraged, so naturally he could not do it in vain, and he needed some food from other tribes to invite him, and this food belonged to the house and the three people who lived in it.

Walking out of the house, he turned around and looked at the hut, and said in his heart: "While it doesn't rain in autumn, there are still four days off before it snows, do more work, when it snows, the grain will be enough to go to the fang market to change a ewe, and the wolfskin is in charge of the livestock, and when breeding, he must be asked to pick the one that grows the strongest...... It's that the ram's horns are like knives, so don't be poked by the lamb when the bluegrass feeds the grass......"

Weighing the tools in his hand, he thought that when his son grew up, he would definitely teach him the work of a mason, and he would definitely live better than others. On the night of the last mid-month break, he discussed with Lancao, and felt that the tribes would one day be separated, and that there would always be those who would eat meat and those who could not even eat bran, and everything would change.

As I passed by the rocks by the river, I was still thinking about these questions, staring at the stones and muttering, "I'm afraid you'll never change." You see, Xia Cheng is still the same as you are, even if he wants to break you and move you away. ”

As soon as he finished speaking, he heard the voice calling his name, and he was startled and thought it was the stone who spoke, so he hurriedly rubbed his eyes and patted his ears, only to hear footsteps behind him, it was a child in the school who was learning things with Chen Jian calling him.

"Tanuki, Ji Xia asked me to call you, there are some things, let you pass."

"In a hurry?" He lifted the tool in his hand a little helplessly, today's work can be exchanged for five catties of food.

"I'm in a hurry, let you go now."

He snorted, knowing what it meant to be in a hurry, although the people in the new army had a mid-term break, but if there was an emergency, it didn't matter whether they were on a ten-day break or not.

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

The boy scratched his head a little embarrassed, took the tool and grimaced and ran away, and the tanuki also hurried to the camp of the new army, although it was a mid-year holiday, but the guards were still very strict.

After entering the innermost big room, I knew that today's event was very important, and several trusted people from the new army and the four clans in the city were gathered here.

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

The tanuki didn't know what was going on, and was a little curious, so he took Jian Chen's copper-stamped letter and went to prepare what he needed, and several people in the house loaded a good wicker basket covered with birch bark on the ox cart.

Ten soldiers of their own tribe were called to follow the ox cart, and seven or eight people in the house rode horses and followed Chen Jian along the grass river to the west, and after walking for half an hour, they stopped in a valley.

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

The soldiers took the order and left, and Chen Jian led the rest of the men to tie the horses to the place and carried the wicker basket into the valley, and after a while the soldiers returned, and two people were separated to guard the valley, and the rest of the people followed closely behind.

The tanuki kept wanting to ask what was so mysterious, but seeing that no one else asked, he had to hold back, but he saw an exposed fire rope that he had cooked with his own hands in the wicker basket.

When he was far away from where the horses were tethered, Jian Chen opened the wicker basket, which contained two fire ropes that these people had helped to make but did not know the purpose of, as well as several clay pots.

Then the tanuki heard Jian Chen's rare serious voice: "No one is allowed to say anything about today's events, remember, no one can say anything." Tanuki, including Bluegrass, can't let her know either. ”

Tanuki nodded, and said in his heart, what do you say, I seem to be a person who talks to women about everything.

Several people had solemn faces, not knowing what was going on, they were all the most trusted and listened to Chen Jian, plus Yu Qian'er who was far away in Echeng, Ji Song who traveled east to explore the way, wolf skins who chased fugitive slaves, and Hongyu who went to the Acropolis to deliver letters, this is the most trusted person Chen Jian can rely on.

Chen Jian first let everyone raise the fire, and he took out the fire rope made of grass and hemp from the situation and said, "Have you always wanted to ask me, what is this fire rope for?" ”

"Yes, it's vinegar and fire brine soaked for so long, I thought it was something to eat."

Jian Chen smiled and put the dried fire rope on the fire and lit it, and proudly raised the fire rope and said, "Look, have you found anything?" ”

Several people came over and watched silently for a long time, and the tanuki looked at Jian Chen's smiling face, and said for a while: "Isn't it just burning very slowly?" If only the other hemp rope had been burned by now, but this rope had burned for so long to be half a finger long......"

It dawned on him that he had approached the arqueo and blew hard a few times, and the originally dim arquebus immediately brightened.

"I know, there is such a fire rope, when we go out to make a fire in the future, we don't have to use a bowstring to turn wood to make a fire!"

Several people looked at each other, and finally couldn't help but ask, "Ji Xia, are you just letting us see this?" This...... Nor can this be said? ”

Chen Jian was speechless, extinguished the fire rope, shook his head and said, "You will talk about it later, let's look at something else first." ”

He took out a fist-sized clay pot from the basket, different from the others, a bit like a gourd, with a small mouth on it, and it was blocked with yellow mud, and a very thin black hemp rope stretched out.

The tanuki glanced at it, and suddenly thought of the training called grenadiment that those sword and shield soldiers had been practicing, and his heart was pounding, and he had always been curious about what it was for, and it seemed that he could know the answer today.

His guess was right, this strange clay pot was the purpose of those sword and shield soldiers' training, maybe not very powerful, but it was still qualified as a cannon battle.

In the world of Chen Jian's previous life, the island country that pondered 100 million jade fragments at the end of World War II also made this type of four-style pottery grenade, and the power was definitely not enough in that era, but it should be very effective in this era. Western Xia used porcelain tribulus terrestris, and Qi Jiajun also used porcelain tribulus terrestris, in fact, they are all this kind of thing.

The estimated molecular weight of the theoretical optimal ratio of black powder is 277, after division, the content of nitrate is about 74 percent, sulfur is 11.5 percent, and carbon is about 13.5 percent.

There is no fixed statement about this thing, the content of gunpowder in Britain in the post-black powder era is slightly lower than that of other countries, probably because they control the saltpeter mine in Chile, Chilean saltpeter is a sodium nitrate with a smaller molecular weight than potassium nitrate, plus sodium nitrate is hygroscopic than potassium nitrate and easy to get wet, and some deliquescent hydrolysates such as paraffin need to be added.

The widely circulated mine warfare ratio is one nitrate, two yellow and three charcoal, which seems unreasonable, but if you think about it carefully, one nitrate should be one catty of nitrate, and carbon and sulfur are calculated according to two, and one catty is sixteen taels.

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

What effect will the fist-thick cannon of paper roll have when thrown into a dense crowd, what effect can be produced by a pot of pottery gunpowder, even if it is not strong, suddenly dozens or hundreds of them are thrown into the pile of people at the same time, it is enough to collapse the army of this era.

Guan Gong didn't have a chance to see the situation of the Macedonian phalanx and the Warring States Seven Heroes in the battle against Qin Qiong, but Chen Jian was very curious about what would be the effect if he encountered a dense phalanx spearmen in this era, and threw some earth grenades or expensive bronze grenades into it, and saw if the strongest anvil that claimed to be able to hold the battlefield could survive the explosion until the cavalry as a sledgehammer outflanked him...... It should be interesting.

With a slight sense of this evil taste, Chen Jian took a soaked and slowly smoldering fire rope and tied it to the twist of this cannon battle, lit the fire rope, and led the people to retreat far away to dozens of paces.

It is customary to cover his ears and open his mouth wide, just like when he was a child, and it is said that opening his mouth will prevent damage to his eardrums.

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

It's a pity that the burning speed of the arquebus is much slower than the incense used to light the cannon when I was a child, and after waiting for a long time, when everyone is impatient, the arquebus finally burns near the lead.

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

Jian Chen stared at the lead 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 hands!" Check it out today! ”

As soon as he finished speaking, a loud noise echoed in the valley, scattered stones flew out of the old high, and the whole valley transmitted echoes, just like the echo of summer thunder.

The blazing flash, the loud sound that did not cover their ears in advance, and the words of Jian Chen before, made the clansmen shocked by the buzzing sound in their ears.

Several people seemed to be stunned, and suddenly knelt on the ground, ignoring the pat of their buzzing ears, and kept worshipping the heavens; A few others ran away from the wicker basket almost subconsciously, away from the things that had terrified them.

Once when they were digging the toilet, they suspected Jian Chen, but after today's loud noise, this 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, and several clansmen pointed to the clay pots with trembling hands and said, "Ji Xia...... You...... Did you really put thunder in a jar? ”

They thought that their ears were buzzing, they were talking loudly, smelling the pungent smell of gunpowder smoke in the air, it was stinking, and some couldn't believe their ears, how could thunder and lightning be put into a jar?

The tanuki also covered his thumping heart, and it took a long time before he said, "This is much louder than popping Yang." ”

There is no bamboo around Xia Cheng, so naturally there is no saying of firecrackers. But last winter, around the time of Chen Jian's previous life, he made some dried poplar trees with insects and burned them in the fire, making a crackling sound, which was very interesting. After that, Xia Cheng had dumplings, and every time they ate dumplings during the festival, the clansmen would also habitually get some poplar poles and throw them into the fire to listen to this sound, and there was a saying that poplars exploded.

When Chen Jian heard the tanuki say this, he smiled and said: "In the future, we will find a way to use this thing to make poplars by ourselves, it must be interesting, it is thunder and flash, and the children will like it." ”

The tanuki looked back at the powder jar and arquebus in the basket, and this time asked with some unconfidence, "Is the arquebus used to light this?" Ignited and thrown into a pile? ”

As soon as he said this, a few people next to him realized that if there was a real war, it would be impossible to make a fire on the battlefield, and if there was no arquebus, this powder jar would basically be useless...... Make a fire in your own army, I'm afraid that no one can throw it that far.

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

Walking to the pile of small stones just now, the stones covering the clay pot have been blown away a lot, and two stones have been pierced into the wood, and the broken pottery shards have knocked down a lot of the yellow leaves of a nearby tree.

A few people stared at the stone that was not too deep embedded in the tree, and were horrified, where can a man be stronger than wood?

These people have never seen it, so they are naturally horrified; Chen Jian has seen a lot, so he is a little dissatisfied, the power of the explosion is not as strong as he thought, and the throwing of pottery is also a problem, it will be broken if it falls to the ground early, and it is estimated that it will be blown up in the pile of people, and it can be one-third.

Because it is an experimental nature, it can be further improved, and in any case, it is also the first thunder that can explode in all seasons of this era.

The successful explosion is just the beginning, and it still needs to make those sword and shield soldiers proficient for a long time, and the safety fuse grenades in the previous life will have endless accidents every year when the recruits are training, and this kind of thing is completely unsafe.

No matter how many stone balls are usually thrown, it is not impossible to hold a grenade that ignites the fuse on the battlefield and is overwhelmed until it explodes in your hand.

The arquebus is an open flame, it is easy to ignite the fuse, and they must be trained in their habits, and only two people cooperate in this way, one person on the battlefield carries the arquebus, and the other teammate carries this unsafe grenade, and throws it with each other.

As for the kind of hat with a wide brim, you don't have to think about it, one is to affect the throwing, and the other is that this era is not the era of flint, as long as it rains, it is impossible to fight, the bowstring will be wet, the discipline is not enough, and there is no need to consider the problem of the hat against rain.

After seeing all this, Jian Chen waved his hand to let everyone sit down, and said solemnly: "Don't tell any of you about this matter today, you also understand, the stone balls thrown by the sword and shield soldiers will be replaced with this thing in the future, and some should be prepared on the towers of Yangguan and Xiacheng, do you think anyone can take it down?" ”

"No, if you prepare a few thousand, you must not be able to attack a few thousand people, it would be better if we made the city wall a little higher."

"Yes, we will definitely not say it to others, we swear to our ancestors, if we say it, we will be killed by thunder...... No, no, it was blown up by this thing. ”

Several people looked back at the wicker basket in shock, and the tanuki licked his lips that were dry because of excitement and asked, "What is this......?" Is it made of nitrate? ”

"Yes, only a few of you know about the entire city, and there may be a few more in the future, but that's all. Tanuki, you used to carry a sword and shield soldier, tell me, can this thing work? ”

"Definitely! If you think about it, this is thunder in the sky, and even if it can't be blown up, those people will kneel on the ground and beg God. It's just that...... When will this thing be known to the people of the city? Those people still don't know what the catapult is for, and they are a little tired of practicing. ”

"It's going to be next year, I called you here just to let you know, this thing...... In fact, it is not a thunderbolt, it is just a weapon that my ancestors used to guide me in my dreams. Thunder and lightning, mountains, rivers, all these can be changed as long as we want to change, as long as we have hands. Do you imagine, if our city piles up so many things like Yashan, will the entire Yashan Mountain be blown up after ignition? ”

The tanuki closed his eyes and imagined this scene, nodded uneasily, stretched out his hand and looked at it for a long time, he couldn't believe that his hand now had the power to make the mountains collapse, but it seemed that what Chen Jian said was not impossible to achieve.

The rest of the people thoughtfully recalled these words, looking at the sky and at the clay pots, with a hint of excitement in their trepidation.

When leaving, Jian Chen said: "After I went back, others asked you what you were doing today, what did you say?" ”

"We didn't see that Ji Xia really had the power of thunder and lightning."

Jian Chen laughed for a long time, shook his head and said, "Stupid, just say follow me to dig stones, everyone in the city knows that I like to dig stones everywhere." ”

The tanuki returned to the city with this lie in mind, and as soon as he pushed the door open, Lancao asked him what he was doing today.

He blushed, this was the first time that the two of them had lied to her after the ceremony, and he stabilized his mind and said in a weak voice: "He Ji Xia went to find a stone......

Lancao didn't care at all, after asking before he could answer, the child cried and went to nurse the child, the tanuki felt quite uncomfortable, always felt that he was holding back a sentence, and always wanted to tell Lancao what he saw today, he even told Lancao that he was naked when he ran back last time to report the news......

After being stuffy for a long time, I ran to the stone outside and sat alone, because the weather was a little cold, so the big stone that was comfortable to sit on weekdays became uncomfortable.

Jumping up hatefully, he picked up a piece of gravel and smashed it at the boulder, but unfortunately the other party did not move, but instead bounced back a stone chip and smashed it on his face, and several women washing clothes next to him laughed.

So the tanuki said indignantly: "I didn't get you before, because I couldn't do it; Now, I don't want to get you because I don't want to, let alone you, I can break it even if it is Yashan! ”

After scolding twice, and venting the uneasiness and suffocating stories in my heart because of lying, I suddenly felt much more comfortable, snorted and turned to leave, leaving the women who were washing clothes looking at each other and not getting it. Finally, a woman thought of some possibility, and whispered something in the ear of the person next to her who couldn't let the child hear, and the person next to her felt that it must be this reason, so the tanuki had such a big temper today, and laughed for a while.
