"Brother Hong hasn't come back yet, did he really stay at Mr. Wang's place and sleep?" The sky was getting dark, but Xie Hong was never seen to turn around, Xiao Yue'er pouted and sighed. [Full text reading]

"Probably not...... "Although she is generous, Qing'er is just a little girl after all, and she is still somewhat resentful of her husband's behavior of not being at home when she comes back.

"Don't guess, Brother Jiang has already passed the word, and Brother Xie is now at Brother Yue'er's place." As soon as the door curtain was lifted, Ling'er walked in, frowning slightly, showing her somewhat gloomy mood.

"Big brother? Could it be that the eldest brother and the elder brother Hong are also ......" Yue'er stared at her eyes in surprise and said with a smile.

"Hey, Yue'er, you're really." Ling'er was angry and funny at the little girl who always seemed to be missing a string, she gently stroked the little girl's bun, and then took Yue'er into her arms, and sighed faintly: "The people of Liaodong have many disasters and difficulties, and Brother Xie is thinking of a way." ”

…… There are many people's hopes, but this method is really not easy to think, the problem of the amount of lead iodide has just been put down, Zeng Zheng immediately put forward another consideration, which makes Xie Hong very worried.

"Brother Zeng, you said that the rocket can't hit that high? It's only a kilometer...... Uh, that's three hundred zhang, where is this? Xie Hong grabbed his scalp and asked a little depressedly.

"The clouds are only three hundred feet above the ground?" Zeng Zheng was also puzzled, it is said that the sky is above the clouds, and the legend says that it is a place where the gods stay, how can there be only such a little distance?

"It should be about the same, right?" The answer is not what he asked, and it is also very troublesome to explain, Xie Hong rubbed the corners of his forehead, he was very worried, the cloud is high and low, and the range shape is always changing, it is difficult to directly define it.

"If you can't get to 300 zhang, 200 zhang should be about the same ......"

However, Xie Hong remembers that as long as it can reach a similar height, it can have the effect of preventing hail, and it does not even need to reach the clouds, as long as the explosion or chemical agents can affect the air flow, it can destroy the rain clouds with hail.

"It's still a little reluct......ant," Zeng Zheng was still shaking his head, "Most of the fireworks in Xuanfu before were only a few tens of zhang high, and a few of them were brilliant in height, and they would not exceed fifty zhang, although today's gunpowder has undergone many improvements, but according to my estimates, at most, it is around a hundred zhang, and if you want to get higher, it's not impossible, but I'm afraid it's too late in time." ”

The main purpose of improving gunpowder is for firearms, and the earth-shaking thunder is used in new gunpowder, so it has the power that ordinary people can not expect, after arriving in Liaodong, Zeng Zheng's main research direction is also how to use it in cannons, and enhance the power of cannons, and rockets flying in the sky are not the same thing.

The strategy was made by Xie Hong, of course he also knew, but when he heard Zeng Zheng's words, he was still very disappointed, a thousand meters sounds like a height that is not worth mentioning in later generations, but in this era it is an extremely difficult distance to cross.

Of course, the most important reason is not that the technology is not good, but mainly because the previous research direction is not on this, otherwise, there should be a way.

But who could have foreseen such a thing? How boring does he have to be to figure out how to put a rocket into the sky, and the higher the better?

However, thinking of the fireworks in Xuanfu, Xie Hong's heart moved slightly, "Brother Zeng, when I was in Xuanfu before, didn't I remember that those fireworks could explode in a delayed manner?" ”

"yes." Zeng Zheng said in a reasonable tone, "Otherwise, how could it be possible to form so many patterns...... By the way, Brother Xie, you were also involved at the time, so you should be very clear. ”

"It can be delayed, that means ......" Xie Hong didn't raise his head, he had words in his mouth, and finally suddenly shouted loudly: "Graded rocket!" ”

"Staged rockets? What's that? Zeng Zheng was taken aback, and with some difficulty repeating the new term he had just heard.

"It's a graded rocket, Brother Zeng, you think, a single firework can fly up to a hundred zhang, so if the first shot reaches its peak, the second shot will be ignited again...... Then the third shot, the fourth shot, and the cycle repeatedly, didn't these 300 zhang go up? Xie Hong was very excited and explained it hand to hand.

"I see." Zeng Zheng nodded, he studied gunpowder very deeply, but he didn't think much about the specific application, but the principle of this rocket classification is also simple, just like the two kicks in firecrackers, and he also understands it as soon as he hears it.

“…… The next thing to do is to control the direction of the rocket, let the second and third stage rockets fly upward, and finally explode at about 300 zhang, isn't this done? ”

"Theoretically, yes, but we still have to experiment." Zeng Zheng is far less excited than Xie Hong, he is a pure scholar-type figure, very interested in various principles, but little interested in specific applications.

"And, Brother Xie, I have to remind you, although a lot of improved gunpowder has been stored in order to cast cannons, there is still a big gap compared to the entire Liaodong, even if it is ready-made, the stock of saltpeter sulfur is ......."

Xie Hong waved his hand and said with a smile: "It doesn't matter, just hurry up and get to work, I'll come back this time, I bring less other things, but there is more saltpeter sulfur, this thing is abundant in the Japanese country, and they won't use it themselves, haha, God really helps me." ”

He was really glad that if he hadn't gone to the Wa Kingdom to grab a circle, he really wouldn't have been able to make so much gunpowder, and even if he had a way, it would be in vain.

"Actually, you don't need to cast ...... in the whole Liao"

"Uh, Brother Bo'an?" There is no need to look back, Xie Hong knows who it is, and when he and Zeng Zheng are discussing, he is the only one who can come in without notification.

"Did you hear it all?" Xie Hong actually wanted to ask, why did the other party suddenly change his attitude? Wang Shouren will say this, which obviously means that he has approved his own method, and now he is here to make suggestions.

"Let's give it a try." Wang Shouren is not a person who holds on to the defects, and the demonstration of the combine harvester also caused him a lot of shock, the efficiency of that thing is too high.

Although the demonstration was not long, the thing was horse-drawn and fast, and every time it traveled through the farmland, it could cut a bundle of grain, except for the person who was doing it, as long as someone sorted it out and loaded it.

With a combine harvester, it is not a fantasy to harvest the fields of the whole Liao in a few days, and with this thing as a footnote, coupled with Xie Hong's various miracles in the past, even if Xie Hong said that he wanted to go against the sky, Wang Shouren was a little skeptical.

The most important thing is that Xie Hong's attitude is also very serious, whether it is what lead iodide is produced, or the so-called three-stage rocket and improved gunpowder, it is all justified and well-founded, and even the data is listed a lot.

Therefore, after listening for a while, Wang Shouren also made a decision and planned to join the Heaven Worship team...... Uh, well, should I say the anti-hail team.

"Although after the catastrophe in western Liaoning, there are black clouds pressing down on the city everywhere in Liaoning, but in fact, the clouds are gathering and scattering from time to time, and the overall trend is to come to southern Liaoning...... "Wang Shouren provided help, mainly in terms of prediction, he knew that Xie Hong and Zeng Zheng did not understand astronomy, so he did not mention the theoretical basis, only said the results, but also saved a lot of trouble.

"In other words, we won't go anywhere else, and we just need to keep Liaonan?" Xie Hong listened attentively.

"It's not that it won't go down, but the scale shouldn't be too big, and the scope won't be too wide, if it's just one or two, you don't have to worry about the loss."

The reclamation order was initiated in Jinzhou and then expanded outward, and southern Liaoning had inherent advantages, so the reclamation ratio here was the highest, and it was the most important place for the New Deal.

Other places such as Liaozhong are fine, but in the area of Guangning, it is already a border, and the reclamation efforts are too great, and it is easy to cause the Tartars to covet it, so the degree of development is not very high, if it is not for the catastrophe like Liaoxi, the losses caused are also within the scope of bearing.

"Then, Brother Bo'an," Xie Hong groaned slightly, and then asked, "Are you sure that you can find the place where the rain clouds are most concentrated?" ”

"What do you mean......" Wang Shouren's eyes lit up, and he immediately grasped what Xie Hong meant.

"Without further ado, too late will change!" Xie Hong said categorically: "The quantity of improved gunpowder is limited, even if it is rushed, it will be difficult to promote it within a few days, if Brother Bo'an can find the place where the rain clouds are most concentrated, then in the past few days, we will mainly make rockets and make lead iodide, and then come to a center to bloom, surrounded on all sides......"

Xie Hong took the map, pointed and explained: "According to common sense, a fire rising on the ground can also affect the clouds, and then destroy the rain clouds so that they cannot form hail, but this catastrophe is menacing, and it is obvious that it cannot be dealt with in ordinary ways alone, so the best way is to deal with it comprehensively, and various methods are mixed." ”

The common sense in his mouth is unheard of by Wang and Zeng, but since they have agreed with Xie Hong, there is no need to care about these details.

"Brother Xie Xian, do you mean to respond comprehensively, and then find the place where the natural disasters are most concentrated, and use the strongest means to break them?"

"Not bad." It is pleasant to talk to a smart person, even if it is an unfamiliar field, but the other party can still quickly grasp the central idea and extend it.

"But it is in line with the purpose of the Art of War," Wang Shouren nodded, and immediately responded: "Okay, Wang will try his best to find the main force of this natural disaster that Brother Xie Xian said. Before the sound fell, the figure was gone.

Although he tried his best, he could see Wang Shouren's resolute appearance, but he had no reluctance at all, and with Wang Shouren's great help, Xie Hong was also confident.

"Brother Zeng, make gunpowder, make rockets, and lead iodide, please leave it to you."

Xie Hong waved his hand calmly, he was very proud in his heart, it is good to have professionals here, we can all be the shopkeeper of such a big matter, which shows that the establishment of the college system is fruitful.

"Brother Xie, you can't go."

"Why? Aren't these things all your specialty, Big Brother Zeng? Xie Hong was surprised.

"There's nothing wrong with extracting lead iodide and gunpowder, but I don't have a clue about the three-stage rocket you mentioned," Zeng Zheng spread his hands and said helplessly: "Fireworks fly into the sky, and then you have to keep your balance and find the right direction...... How can this be done? ”

"......" Xie Hong was at a loss, you ask me, who will I ask?" This is the principle of rockets in later generations, according to common sense, isn't it enough for the traverser to be guided, why did he get to me, and he had to do it himself?

Seeing Xie Hong's blank gaze turned, Zeng Zheng shrugged his shoulders again, and gave him a helpless look, he is a chemist, not a physics expert, of course he doesn't understand.

My brother just came back from a business trip, just got off the boat, and didn't even have time to take a shower...... And more importantly, my brother's three-fly plan is far away! Xie Hong let out a silent shout, and the ultrasonic wave that was excited startled countless fish and shrimp on the bottom of the sea......
