"Obediently, such a small bamboo tube can make such a loud noise" Cheng Yanjin sat on the ground, rubbing his ears and eyes in amazement."
Zhijie, it's cold on the ground, get up quickly," Qin Qiong said to Cheng Yanjin playfully."
Hey, when did I sit on the ground" Cheng Yanjin hurriedly got up and said as if he was confused.Once again, the crowd was amused by him.Two guards ran towards the target, one carrying the target to Li Shimin and them, and the other was looking for an arrow.After a while, the target was carried over, and everyone hurriedly gathered around to observe.I saw a round hole the size of a palm appear on the target.Around the entrance to the cave, the wood stubble is uneven.The eldest grandson Wuji reached out and pinched the thickness of the target, and then sighed: "It's so powerful, I think the iron armor can shoot through." ”At this time, the soldier who was looking for the arrow also ran.He presented the arrow to Li Shimin.At this time, the arrow was only a bare iron rod, and the small bamboo tube on it was nowhere to be found.Come to think of it, when the tip of the arrow pierced through the plank, the small bamboo tube had already fallen off.Li Shimin took the arrow and said in surprise: "Why is it so hot" Zhao Yunze explained: "This arrow is propelled by the gas produced by the combustion of gunpowder, and when the gunpowder burns, it will naturally conduct heat to the shaft of the arrow." ”"I see" Li Shimin nodded, looking at the burned black arrow over and over again.Qin Qiong said at this time: "If this arrow is used against cavalry, it is the sharpest.The loud noise startled the horse, the tip of the arrow pierced through the armor, if ten thousand arrows were fired at once, even in the face of more cavalry, he was not afraid. ”Eldest Sun Wuji nodded, agreeing with Qin Qiong's opinion.He asked Zhao Yunze again: "Is this thing expensive?"
No matter how good a weapon is, if the production cost is too high to equip the army in large quantities, it will be meaningless.Zhao Yunze looked at Li Shimin with an inquiring gaze, and Li Shimin nodded at Zhao Yunze.This is to tell Zhao Yunze that it doesn't hurt to say it directly.The generals brought by Li Shimin today are not only from the Qin Palace, but also participated in the Xuanwumen Change, and they are his hardcore cronies.Therefore, Li Shimin does not intend to have any reservations about them.Zhao Yunze understood and hurriedly replied: "The key to this arrow is gunpowder, and gunpowder is made of sulfur, charcoal and saltpeter, and the cost is very low.That is, charcoal is slightly more expensive, and the other two, although they are scarce on the market, are rarely used by the people, so the price is lower than charcoal. ”The eldest grandson Wuji silently calculated for a moment, and then said: "In this way, it can be manufactured in large quantities."
Cheng Yanjin couldn't help but interject at this time: "Eldest grandson, after the incident, you will discuss it slowly, and let Zhao Xiaozi release all the things he brought."
This thing is a pleasure to listen to. ”Li Shimin smiled and nodded at Zhao Yunze.Zhao Yunze picked up another bamboo tube, and he brought a total of five bamboo tube rockets this time.Li Shimin and the others are smart now, so they simply stay away from Zhao Yunze.Another bamboo tube was lit, this time a little unsatisfactory, and the rocket fired did not hit the target.However, the maximum flight distance of this rocket was also measured, which was about 300 steps and about 450 meters.At this time, Zhao Yunze also completely fulfilled his lie.Although this distance was much closer than the actual distance between him and Jieli Khan when he was on the banks of the Weishui River, Zhao Yunze was acting alone at that time, and no one knew where he was hiding, so he could barely justify himself.As for the accuracy, it's better to fool, maybe it's my brother's character explosion at the time, maybe it's really God's help in the dark, anyway, I used this broken banner to break it, believe it or not.Thinking about it, Li Shimin and his ministers preferred to believe that Zhao Yunze was helped by heaven at that time.To help Zhao Yunze is to help Datang, and to help Datang is to help Li Shimin.This is the best means of political propaganda.At the very least, you can make a fool of yourself.The remaining three bamboo rocket rockets were also cast by Zhao Yunze in turn.One of them hit a target a hundred paces away, shooting a hole that was even larger than the previous one; The other one flew in an unstable direction, drew an arc directly in the air, and flew to the side of the school field; The last one was even worse, it was simply dumb and didn't shoot a rocket at all."
Zhao boy, you can't do this thing" After the five bamboo tube rockets were cast, Cheng Yanjin shook his head and said cool words.Wei Chigong glared at him fiercely, and distinguished Zhao Yunze: "Yunze made these things in a hurry, and occasional mistakes are inevitable" Zhao Yunze himself said: "Firearms, if they want to be really used in the army, they must go through repeated tests.The quantity of the charge, the size and weight of the equipment used, and the degree of finesse with which it is made must be optimal, so that the quality of the firearm can be guaranteed.General Wei Chi is right, a certain hasty restraint is inevitably a little rougher. ”Li Shimin comforted Zhao Yunze and said: "Yunze has tried his best, and I and you Aiqing have also witnessed the power of the rocket, as for those details, the flaws will not be hidden, and they will be slowly improved in the future." ”Qin Qiong picked up a small clay pot with interest and asked Zhao Yunze: "This is a thunderbolt" Zhao Yunze nodded and said: "General Qin has good eyesight, this is a thunderbolt." ”Cheng Yanjin pursed his lips and taunted Zhao Yunze and said, "Hmph, I'm really good at sycophancy."
The two things you brought, except for the rocket, which is a thunderbolt, the rocket has been released by you, and the rest, even a fool knows that it is a thunderbolt, what kind of good eyesight does this need" Zhao Yunze was embarrassed by Cheng Yanjin's words.Qin Qiong asked with a smile: "Zhijie, are you saying that I am a fool" "A fool dares to say that Second Brother Qin is a fool, I am afraid that you will smoke me" Cheng Yanjin said this without a preface.Everyone immediately pointed at Cheng Biting Jin and scolded with a smile.After laughing for a while, Li Shimin said to Zhao Yunze: "Then let me see the power of this thunderbolt again." ”Zhao Yunze immediately arranged for the soldiers to rearrange the venue.This time, the scarecrow used in the school field was used.Under the command of Zhao Yunze, those scarecrows were arranged into a small military formation by the soldiers according to the pattern of the army.For thunderbolts, Zhao Yunze's confidence is even greater, after all, he has already used it once in actual combat.Zhao Yunze picked the best quality of the sulfur charcoal and saltpeter used in the configuration of gunpowder this time, and after buying it back, he simply purified the sulfur and saltpeter, so Zhao Yunze was very optimistic about the thunderbolt made this time.After the field was arranged, the soldiers withdrew.Zhao Yunze picked up a clay pot and lit it, and threw it towards the scarecrow formation.The clay pot fell to the ground, and after a few seconds, there was an explosion of "boom", and suddenly black smoke filled the air, and the scarecrow army formation was covered in black smoke.When the black smoke cleared, everyone hurriedly rushed to the explosion to take a look.Within a five-step radius, the scarecrow was blown up, and the more you go to the center of the circle, the more serious the damage to the scarecrow becomes, and several scarecrows near the center of the circle are not only blown away, but also the wooden sticks supporting the scarecrow are also blown up and burst.Some straw also ignited a raging flame, and the scene was a mess.The only thing that was clean was the center of the circle, where a two-meter-sized area was swept away by the air wave generated by the explosion.At the same time, this pure ground also forms a shallow cone-shaped crater.At its deepest, it is about 20 centimeters.The crowd was stunned.Wei Chigong said: "The explosion effect this time is much stronger than the batch made in Jingyang. ”Zhao Yunze said: "I purified sulfur and saltpeter.However, limited to time and purification utensils, the extracted sulfur and saltpeter are still not very pure.If the purity of sulfur and saltpeter is enhanced, and the quality of charcoal used is better, the explosive effect will be stronger. ”Li Shimin suddenly looked playful, and Zhao Yunze said: "I was still worried that you wouldn't be able to buy good materials, so I ordered someone to ask for some from the Luo Immortal who gave the Emperor Taishang Emperor alchemy, but when they sent it to your home, you kid was drunk and crazy." ”"The Emperor Taishang is taking pills," Zhao Yunze asked Li Shimin in surprise.Is this a dead old man, the ancient pill is not a good thing, and there are many heavy metals in it.People who want to borrow and take pills to live forever are basically counterproductive, but they will die of chronic poisoning and early death.Li Shimin waved his hand and said, "Don't interrupt, just say, do you have a way to enhance the purity of sulfur and saltpeter" Zhao Yunze also temporarily suppressed his worries about Li Yuan, and replied: "There is a way, it takes a little more work. ”Li Shimin nodded and said, "That's good."
Although the power of this thunderbolt has already made me breathtaking, it is good to be stronger after all. ”Eldest Sun Wuji said at this time: "The power of this thing is even greater than that of a rocket, but even if it is thrown by hand, it is too close after all, and I am afraid it can only be used against infantry." ”Cheng Yanjin suddenly said at this time: "Make it bigger, throw it with a stone thrower" Everyone looked at Cheng Yanjin in surprise."
You rammer, you actually got the hang of it," Li Shimin scolded with a smile.Everyone laughed.Qin Qiong pondered silently alone for a while, and asked Zhao Yunze: "Yun Ze, after seeing the power of this thunderbolt, if it is possible, gather a lot of gunpowder and bury it under the city wall, will it be able to destroy the city and pull out the village" Zhao Yunze secretly praised in his heart, these people who are here today are indeed generals, just by observing, they can draw inferences from one another, and point out all the uses of gunpowder in military affairs."
That's how it should be."
Zhao Yunze nodded and said.Li Shimin was silent for a while, and said very seriously: "Gunpowder is an artifact of the Tang Dynasty given to me by God, and everyone must take it seriously.Only Zhao Yunze secretly slandered: What a godsend, it's obviously me who made it up, "Jingde, these sergeants on the school field today are temporarily transferred to your camp, and they must be more restrained, and they must not contact other sergeants, let alone leave the camp."
When I find a suitable place, I will resettle them. ”Li Shimin said to Wei Chigong again."
The minister obeys the order" Wei Chigong gave his hand to receive the order.Li Shimin also said: "I want to set up a firearms manufacturing department to specialize in the manufacture of firearms, what do you think?"
”The eldest grandson Wuji took the lead and said.Several other generals immediately seconded the motion
