Chapter 621 The prototype of the killer

In July, the heat was hard, and the room was unbearably hot. Wan'er ordered people to sprinkle water on the bluestone clear space in the back garden and bring bamboo beds and bamboo chairs on it. After dinner, Song Nan and his wives and concubines came to the back garden to enjoy the cool.

This has been the rule of the Song family since they entered the summer. The melons and fruits and tea were placed on the bamboo bed. Everyone sat around Song Nan and chatted and had fun, waiting for the summer heat to fade before returning to bed. For Song Nan, his wife and children sat around, and their wives and daughters sat around, and the soft words of their wives and beautiful concubines, and the noise of the children made Song Nan more relaxed. The brain is also very fresh, and many major events were decided on this occasion.

That night, the topic of the Song family sitting in the back garden was that Lu Qingli and Yang Kooer spent 50,000 to 60,000 taels of silver to make those iron things. The idea of multi-tube guns had been put forward two years ago, and it stopped because of insufficient funds. After restarting two months ago, the adequacy of silver also made the progress smoothly. .

Lu Qingli happily described the power of the multi-tube gun in today's live-fire experiment to Song Nan. After the collapse of another rockery in the garden last month, at the strong request of everyone, this destructive experiment was forced to move to the small depression of Shilizhuang's manor in the south of the city. It took more than ten days to build a house to level the ground, and Lu Qingli and Yang Koer went back and forth every day.

"You don't know that today, Koer and I conducted our first full ammunition launch test and actually collapsed half of the small mountain wall on the west of the hillside. Oh, my God, the sound was like thunder. Koer lit the fire and covered her ears and ran away, almost fell into the puddle, hahaha." Lu Qingli laughed and pointed to his hands and feet.

Yang Koo'er blushed and said shyly, "Who fell into the puddle? You don't dare to hide in the distance for a long time and dare not ask you to light a fire. How dare you say.

Lu Qingli took Yang Koer's shoulder and smiled, "Okay, okay, I shouldn't make fun of you, okay? I'm also a coward, okay?"

Song Zhidao, the young master of Song Mansion, who had been walking around all over the ground, came crookedly and followed his teeth and said, " Coward!"

Song Nan and all the girls coaxed and laughed. Lu Qingli reached out and twisted Song Zhidao's white and tender face and said fiercely, "Kid, if you talk more, Aunt Lu will throw away all your toy snacks tomorrow."

Song Zhidao hurriedly fled to Dai Suer's arms. Dai Suer hugged and kissed and comforted her, "My aunt loves you the most. I'm teasing you."

Song Nan asked with a smile, "Is it really so powerful? You've been talking for a long time and I don't understand what you're talking about. What I want is the range, accuracy, and whether there is a risk of explosion. Dozens of firearms are not a simple combination. They will definitely affect each other when they are launched. What I want is these things.

Lu Qingli stamped his feet and said, "I know it's thankless. It's easy to do what you said. More than 20 helpers below and I are like black charcoal every day, and I haven't seen you say a word of relief."

Song Nan hurriedly said, "Thank you for your hard work. I don't say anything. I'm worried about it. I know it's not easy to do, otherwise how can I ask you two masters to do this thing? I'm just talking. If you let me do it myself, I won't worry about it. You and COER are both very good. I can only leave this matter to you two. It's very important to me, understand?"

Ye Fanggu said, "Qingli, don't talk like that. Who said he doesn't care about you? Every day, I personally ordered someone to send you iced melons and fruits, and bought the most comfortable and spacious carriage for you to go back and forth. The carriage is like a small house. Have you ever seen anyone in such a splendid carriage? Being so busy on the construction site, Suer also sewed a cool cloak for you. The little princess bought Biyunlou's secret sunscreen for you. Who didn't remember you?

Lu Qingli is not really angry, but just complained casually. At that moment, she turned her face and smiled and said, "I know, just say it casually, Koer, don't you remember any data? This is our business. Don't just watch the bustle and talk. Let me tell you, if this happens, the matter of you entering Song Mansion as the fifth lady will be nailed.

Dai Suer blushed and stretched out her hand to grab Lu Qingli: "If you chew your tongue and rotten your mouth, who wants to be the fifth lady?"

Lu Qingli smiled and dodged Yang Koer's claws and reached out to pick up the pink pair sitting on Ye Fanggu's knee as a shield. After laughing for a while, seeing Song Nan's face full of expectation, Yang Koer sat down and said, "There are 64 fire pipes in parallel. I'm afraid there are some mistakes in the idea of as many fire pipes as possible mentioned by Brother Song before."

Song Nan smiled and said, "I just hope it's powerful enough. The more tubes you have, the worse the effect will be, right?"

Yang Keer nodded and said, "Sister Qingli and I have experimented with 108, 88 and 64, and found that too many parallel fire pipes will cause mutual influences, causing overheating, deformation and other effects. Due to the too dense juxtaposition, the thermal insulation between each other is too thin. If the placement is too loose, it will not It can achieve the lightness of being able to go uphill and cross the ditch as you said; so we decided 64 tubes as the best way after the experiment.

Song Nan nodded slowly, and there were many 64 tubes. If it could succeed, it was also an amazing firearm; 64 rocket guns, which was not a joke.

"According to your suggestion, after changing the original circular juxtasis to square juxta, the original uneven blow problem has also been improved. Now it is eight horizontal and eight vertical parallel, and the strike distribution is also very uniform."

Song Nan nodded and said, "eight horizontal and eight vertical, eighty-64, exactly sixty-four tubes; if there is a gap in the middle, in fact, there is no need to fill the heat insulation. It is best not to connect it as a whole, so that the damage of one tube or several tubes does not affect the launch, and it can be removed and replaced."

Yang Koer said, "Well, this should not be difficult. Including the iron plate behind the base wheel, it weighs a total of 823 catties. Two strong horses can be pulled. If there is manpower to help, it will be fine to go uphill and downhill.

Song Nan said, "How far is the range?"

Yang Keer said, "About 50 steps, farther away from the target, and the power is not enough; today, the distance between the experiment with Sister Qingli is 40 steps, a little away from the target on the cliff, but the power is really amazing, and half of the cliff collapsed."

Song Nan muttered, and Lu Qingli said, "Do you think the range is not far?"

Song Nan nodded and said, "Yes, I thought I could shoot a hundred steps away, the same distance as the crossbow, but now it seems impossible; but it is understandable that the previous firing range was only 20 or 30 steps, which has nearly doubled the distance, and it is multi-pronged, which is already very good. In fact, there are ways to increase the range. It is possible to increase the barrel and increase the strength of gunpowder, but in that way, it will lose the effect of mobile strike that I hope. If I want to fight far, I might as well cast a cannon. I'll take a look tomorrow and finally determine the model. Well... I forgot to ask, how much does it cost to build such a door?

Lu Qingli and Yang Ke'er looked at each other. Yang Ke'er refused to say anything. Lu Qingli gritted her teeth and said, "16,000 taels of silver, excluding ammunition."

Everyone exclaimed, and the little princess smacked his tongue, "My God, what's the use of this thing burning money like this? Besides, the husband should ask the court to pay for it. Is your husband going to make it himself?

Song Nan calculated that the cost of 16,000 taels of silver is indeed too high, and the consumption of ammunition is actually a big one. Imagine that this thing is sent out at once, which is the cost of hundreds of taels of silver. After a battle, he casually shoots a few rounds, which is tens of millions of taels of ammunition. This is a bottomless hole.

And the little princess is right. If this kind of heavy firearm is made without the permission of the court, something big will happen. After all, the previous firearm was just a light firearm, and it saved Zhengde's life at a critical time, so nothing unpleasant happened. After that, he also pretended to ask the court to make it, which only doubled the cost. In the end, the court really had no money to make it, so it acquiesced. But now, if this thing is made, once it is discovered, it will definitely cause panic, and Zhengde may also doubt his behavior.

Song Nan waved his hand and said, "Anyway, the firearm needs to be finalized, and I will solve the rest of the things properly. This firearm is temporarily named Mrs. Song's rocket launcher. Tomorrow afternoon, I will go to Shilizhuang to see where Qingli and Miss Koer are waiting for me."

Everyone chatted for a while, and the night was getting darker; the children did not know when they fell asleep in their arms. The maidservants were driving mosquitoes with fans, and the heat gradually faded, and everyone also left their rooms to rest.

Song Nan did not go back to his room to sleep. He sat alone in the garden and looked up at the starry sky. He was a little upset and occasionally sighed gently.

"Does your husband have something on his mind?" I don't know when, Dai Suer turned back, gently sat down next to Song Nan, and asked softly.

Song Nan smiled and said, "Why don't you sleep?" What happened on the construction site during the day is enough. Go to bed early.

Dai Suer shook her head and said, "I'm not tired. My husband has something on his mind today. I can see from dinner that what happened?"

Song Nan shook her head and said, "It's better not to talk about official affairs. It's already a rule not to mention official business in the house, so as not to implicate everyone's mood."

Dai Suer said, "I just want to share my husband's worries. If my husband doesn't say that I won't talk much, will I sit with my husband for a while?"

Song Nan reached out to hold Dai Suer. Dai Suer cleverly snuggled up in Song Nan's arms without saying a word. Song Nan couldn't help saying, "Oh, it's okay to tell you. You are just a curious kitten. In fact, you want to know, but you don't force yourself, but you don't walk in front of me and wag your tail."

Dai Suer laughed and said in a greasy voice, "Where does the slave have a tail?"

Song Nan reached out and touched her slippery buttocks and whispered, "You are a fox, and your tail is gone."

Dai Suer's smiling body trembled, and her hands around Song Nan's neck rubbed in his arms. Song Nan rubbed her familiar and plump body for a while and said softly, "After this morning, the emperor invited me to meet him."
