Why did Wei Cheng only ask Wei to provide sulfuric acid and charcoal? Because these two things are available in this era, and they are available in large quantities, and he only needs to purchase potassium nitrate (saltpeter).
Of course, saltpeter was also available in this era, and it was also a very common medicinal stone, also known as saltpeter.
However, there is certainly no way to compare natural potassium nitrate with the precise ratio of artificial potassium nitrate produced by later generations. The natural power of gunpowder made from the two is also very different, which may mislead interested people.
Wei Cheng knew that once he took out the gunpowder, he would be investigated. Then simply quell their curiosity at the source. Even if they mixed the gunpowder by mistake with the saltpeter, they would be surprised to find that the gunpowder they prepared could not achieve the expected power.
You know, the precise ratio of black gunpowder was finally obtained after hundreds of years of trial and error. In this era when there was no concept of gunpowder, it was simply difficult for the ancients to mix black gunpowder with real destructive power. Ascend to heaven.
In addition, Wei Cheng deliberately concealed the existence of potassium nitrate (potassium nitrate). When someone actually prepared gunpowder by mistake, he himself would have probably produced TNT.
Of course, Wei Cheng has another purpose. The network supervision in later generations is very good. He can purchase potassium nitrate alone. If he then purchases sulfur and other materials in large quantities, I am afraid that under the supervision of big data, some Bobo will come to him for tea.
Therefore, no matter what the purpose is, it is a wise choice to let Wei Hao help prepare sulfur and charcoal.
That night, Wei Cheng took the time to return to modern times. There is also half a pack of potassium nitrate in the warehouse at home, which was purchased before to process herbal medicines. Some medicinal materials need the help of potassium nitrate to catalyze them.
Wei Cheng purchased another twenty bags of potassium nitrate online, and then returned to the Three Kingdoms era. And using potassium nitrate, sulfur, and charcoal, according to the proportions on Baidu, I made a clay bomb. It was the small bamboo tube just demonstrated in front of Zhengtou and Jin Lao. The lead was a pack of children's toys bought in the supermarket.
This night, the hardest part was for Shengtou and Jin Lao. In order to ensure that the formula would not be leaked prematurely, Wei Cheng only allowed them to have access to the black powder formula.
In addition, Zhengtou himself is a carpenter and Jin Lao is a goldsmith. The two of them can make what Wei Cheng wants according to Wei Cheng's requirements.
A night of silence. Time soon came to the early morning of the next day. According to the rules, Cai Yan took Wei Cheng to greet Wei Hao.
Wei Cheng didn't want to go because he was afraid of being exposed in front of Wei Hao, a cheap father. After all, he had occupied his son's body.
Cai Yan was curious about why he was so resistant to seeing his father. He held Wei Cheng's hand and asked carefully: "Husband, I felt your mood changed when I returned home yesterday. Are you deliberately avoiding my father?" Wei Cheng's heart skipped a beat and he looked at her awkwardly.
Seeing this, Cai Yan stretched out his hand to touch Wei Yan's cheek and said with tears in his eyes: "Is it because of Yan'er that you don't want to talk to my father-in-law? If so, then there is no need. Yan'er never blames my father-in-law. Send Yan'er back to the Cai family."
"???" Wei Cheng was stunned, remembering what Wei Gong said when they first met. At that time, Wei Gong said that Cai Yan was sent back to her parents' home in anger by Wei Hao because he ran away from the Wei family.
Wei Cheng rolled his eyes, held Cai Yan's small hand with his backhand, and comforted: "Don't think too much, I am not doing it because of you, but he is indeed too much. How can I get angry with you because of my willfulness." Cai Yan was moved to tears.
Hey, I'm such a smart little guy. I moved Xiao Yan'er without having to meet the old man. I killed two birds with one stone.
"Sir, it's almost time. Duke Wei and the clan elders are already waiting at the south gate." Wei Cheng looked for a voice and went out. Xu Ding stood far outside the courtyard gate, leaning sideways and embarrassed to look in.
Cai Yan shyly broke away from Wei Cheng's arms and said affectionately: "Husband, please go and take care of something. Yan'er goes to see the mother and daughter yesterday." Wei Cheng gently rubbed her little hand and said, "That's fine, you Go, if you hear any noise later, don’t be afraid. The bigger the noise, the greater the confidence we have in defeating the Baibo Army, which is a good thing, you know?" Cai Yan didn't know what the big noise was, so he just nodded obediently. , urging him to get busy.
at the same time. On the outer wall of the south gate of Wei Zhuang. Wei Hao and a group of Wei clan members had been waiting for him for a long time. They said it was Sishi, but in fact they had arrived early at Chenshi.
As soon as I arrived at the outer wall, I saw two carpenters from Wei's family doing final inspections on a large wooden shelf.
Seeing Wei Hao and others, the two carpenters bowed respectfully and greeted them. Zheng Tou just nodded towards them and only saw the wooden frame, which made Wei Hao and others full of curiosity.
Wei Hao stepped forward and asked, "What is this?" Chengtou met Wei Hao twice, respectfully clasped his fists and saluted, and said, "This is a stone throwing tool."
"Throwing stone?" Wei Hao and others looked at each other, thinking it was some kind of incredible magic weapon, and they all opened their eyes wide.
At this moment, Wei Cheng arrived with Xu Ding and his party. Seeing Wei Cheng, Wei Hao felt heartbroken again, my son.
Wei Cheng casually bowed his hands to Wei Hao and others, and then asked Chengtou: "How is it? Have you tried it? What is the range?" Chengtou immediately clasped his fists and replied: "I have tried it a few times, and the longest range is eight. One hundred steps means that the projectile cannot be too heavy or too light. If it is too heavy, the maximum is three hundred steps. If it is too light, there is no way to control the position. About ten to fifteen kilograms is best." Wei Cheng nodded with satisfaction after hearing this: "That's enough...thank you for all the trouble." Chengtou said he didn't dare.
Wei Cheng looked at Xu Ding aside and ordered, "Go and see if Mr. Jin is ready." Xu Ding bowed his hands and was about to retreat when he heard Mr. Jin's tired and excited voice: "No, no, this old man is here." Wei Cheng looked back and saw the old man walking over with a wooden box in his arms. Although his face was full of exhaustion, his eyes were shining.
"Done?"
"It's done!" Wei Cheng and Jin Lao seemed to be playing charades. The others looked confused except for weighing their heads.
Mr. Jin walked up to Wei Cheng and whispered: "I made two pills in total, each weighing about three kilograms." Wei Cheng frowned slightly, was it only three kilograms?
He looked at Zheng Tou and asked, "How far can three pounds fly?" Zheng Tou cupped his fists and said, "If accurate positioning is required, within five hundred steps is no problem. If accurate positioning is not required, seven or eight hundred steps will be fine." Well, it just drifts a little, and the error is about thirty steps."
"Thirty steps isn't too many steps." Wei Cheng smiled with satisfaction. At this time, Wei Hao and others really couldn't stand anymore, and they all came up to ask Wei Cheng what he was planning, what about three hundred steps, five hundred steps, eight hundred steps... Gu Zhong Wei Cheng laughed and was about to speak.
A man was galloping towards the city on horseback. The direction he looked at should be the city gate to the west.
"My lord, my lord, I have found nearly a hundred cavalrymen from the Baibo Army. They are suspected to be enemy outposts, trying to find out the strength of our defense." Wei Cheng and others looked back. Zhang Fei got off his horse and ran to the outer wall, pointing to the west. Said: "Look, they are coming." Everyone looked in the direction of his finger, and sure enough, at the end of the outer wall, dozens of cavalry suddenly came on horseback.
The leading cavalryman carried a flag on his back. As he got closer, he could clearly see the word "白波".
The group of cavalry seemed to have discovered Wei Cheng and others on the outer wall, and quickly rode away from the outer wall. At the same time, some people took out their bows and arrows and looked at the people on the outer wall warily, possibly launching an attack at any time.
Zhang Fei said: "They came all the way from the north gate. Brother Xu sent someone to inform me. I think it is necessary to keep them. Young Master, let me take people out to give them a show of strength. How dare there be less than a hundred people." So arrogant." Wei Cheng's expression changed, and he looked at the slinger aside, "Hey guys, this is a practice target delivered to your door."
Wei Cheng then looked at Chengtou and Jin Lao and said, "Aim at them. It doesn't matter whether they are accurate or not. Let's warm up first." Chengtou laughed and said to Jin Lao, "Jin Lao, I'll leave it to you. Well, I'm afraid I'm careless, what if that thing... Haha, come on, come on, I'll help you pull the lever and aim." There was a mysterious smile on Mr. Jin's face. When he heard that he was asked to do it, his whole body As if ten years younger.
He looked at Wei Cheng, who nodded towards him to show encouragement. Seriously, it's impossible not to be nervous.
After Mr. Jin saw the power of that small bamboo tube last night, he heard that the power of the gadget he made was more than ten thousand times that of that small bamboo tube. When he operated it all night, he was trembling with fear, for fear of destroying his own. .
"Then, let me do it." Jin Lao held the wooden box in both hands and came behind the trebuchet. He aimed his head in the direction and said, "Mr. Jin, that's it." Seeing this, Wei Cheng pulled everyone back and took about ten steps. Uneasy, he took two more steps back.
Just, a little timid. When Jin Lao and Chengtou turned around and saw this scene, they felt terrible.
Wei Cheng said awkwardly: "It's not that I don't believe you, but I think it's more comfortable to stand here." Mr. Jin and Zhengtou said: "..." At this time, the small group of white wave cavalry was almost at the gate.
They were afraid that the people on the wall would fire arrows at them, so they deliberately avoided the distance of more than 200 meters, which was beyond the effective range of ordinary crossbows.
Seeing that the people on the outer wall suddenly disappeared, and only two people stood on it and looked at them, the leading cavalry suddenly laughed: "Humph, what a bullshit aristocratic family, they are just a bunch of cowards." The men behind him were also unscrupulous. They slandered the so-called aristocratic families, saying which family had moved their families away from Hedong to avoid them, and which family's daughter was so fun that she would go to the dungeon to play again.
The unbearable sounds came one after another, completely forgetting that they came here to inquire about Wei Cheng's movements.
Just when they were talking and laughing and riding their horses, they planned to continue to circle Wei Village in order to complete their mission and go back to deliver their business.
Xilulu...
"What's going on? Why are the horses going crazy?"
"You bitch, stop running around, go forward, go forward!" The next moment. boom! Less than five meters in front of them, there was a huge roar, and then a wave of air rushed towards them with a scorching breath, like an overwhelming force, and even the horses under them were thrown away. He couldn't get out, let alone people.
The slag-filled metal pieces and stones in the air wave were more like life-threatening soul-stealing nails. The moment they flew into the air, everyone including the horses were riddled with holes. It’s not alive anymore.
And this is exactly what happened. Except for a few people and horses who were farther away and farther back, the original team of eighty people had been completely wiped out. There were broken arms, rotten flesh, and dead people everywhere. The people's eyes were wide open, and until the moment before they died, they still didn't know what caused the horses to suddenly go crazy.
Three hundred steps away, the heavy man on the outer wall of Wei Zhuang stared dumbfoundedly at the place where the thick smoke gradually dissipated. The white wave army cavalry who fell to the ground in pieces were still there showing off their power just now, but now they have turned into a muddy ground.
Wei Hao and other clan elders immediately opened their mouths and could not close them for a long time. Xu Ding, Zhang Fei and others standing behind Wei Cheng also opened their eyes wide and swallowed hard at the same time.
Only Wei Cheng was calm at the scene, while the hands-on Zheng Tou and Jin Lao were also a bit unbearable at this time. Their hands were trembling, their pupils were dilated, and they looked quite irritated.
And the next moment. Everyone who came back to their senses avoided the wooden box at Old Jin's feet.
Because there is also a big shining golden ball in the wooden box. There are not too many decorative patterns on the ball, only a big word "Thunder" and a dark green lead.
Mr. Jin turned back to look at Wei Cheng and stuttered: "Master, Master, is this ten thousand times what you said? Forgive me for my blindness, this power is probably more than ten thousand times more powerful than a bamboo pipe. You, you... ...If I was not careful last night, Gulu." Jin Lao was obviously scared.
When Wei Cheng saw this, he hurriedly comforted him: "Didn't I tell you to pay attention to Huo Zhu? It's okay. The fact that you are standing here well is the best proof, hahaha." Jin Lao looked at him aggrievedly and wanted to say I want something, but I really don’t know how to express it.
When he still wanted to speak, Wei Cheng was already surrounded by Wei Hao and others.
"Cheng'er, is this the Tiangang Divine Weapon? Is it the rootless fire you mentioned?"
"Oh my god, how could such a small iron ball cause such huge damage."
"It must be the Tiangang Divine Weapon. With such a magical weapon, what should I, the Wei clan, have to fear? The mere Baibo Army can easily kill them."
"But that's not right. A rootless fire cannot be extinguished by wind or water. How come the fire disappeared in a flash?" Everyone pulled Wei Cheng and asked, and all the old guys' faces were full of anger. Thousands of whys and a look of surprise that cannot be concealed.
Wei Cheng was shaken and confused, and said angrily: "This thing is called Lei Zhenzi, not some rootless fire." Wei Cheng had already thought about the Thirty-Six Divine Weapons of Tiangang and the Seventy-two Heavy Weapons of Earthly Evil. , thirty-six types of firearms in the front, and seventy-two types of cold weapons in the back.
The name Lei Zhenzi was something he just came up with, and it felt quite appropriate. Wei Hao and others looked at each other in shock: "Lei Zhenzi!" Zhang Fei and others were also surprised and happy: "Lei Zhenzi, he must be the Divine Weapon of Tiangang." Wei Cheng looked around at everyone, and then said with a smile: "That's right. This object is Lei Zhenzi, one of the Thirty-six Divine Weapons of Tiangang. It ranks higher than Rootless Fire. It is just difficult to make and very dangerous. In the future, unless it is absolutely necessary, it is better not to rely too much on it. , so as not to blow yourself up." It would be better to scare them, so as not to rely too much on firearms, thus wasting the practice of traditional ancient martial arts.
