Zheng Xuan asked again: "Girl, I won't tell you, I really don't have any martial arts. However, the art of gunpowder has been quite successful from time to time. I don't know what I can do for you in the future?"

Yi Dan said: "Mr. Zheng, you don't have to be too modest, as long as Mr. Zheng Fan is like your eldest brother Zheng Fan, you apply the art of gunpowder to the siege of the city and the land, I dare to guarantee that in the future, our actions will definitely get twice the result with half the effort." ”

Zheng Xuan said: "Okay, this is no problem. My gunpowder skills have now been a little successful, and they have made great progress compared to when my eldest brother was in Yuzhang and burned the Longsha Gate. It has been improved from a simple burning method to an explosive force. I also often use the results of fish bombing as a basis for further research and improvement. I don't know any of this, can it help you?"

Yi Dan said: "Great, Mr. Zheng, either we will use this newly developed gunpowder first to help Mu Daxia solve the current dilemma." Maybe Mu Daxia will be happy and agree to our request to join the uprising. ”

Zheng Xuan said: "That's right, I also have this intention. If Mu Daxia can understand the righteousness and stand on the side of the right path, it will be our great blessing. ”

When Pi Kaiyuan heard this, he smiled and said, "That's great, then please Mr. Zheng clean up and go to Tianya Town with us to see my master, right?"

Zheng Xuan asked, "You tell me the current situation first, and I'll see what preparations should be made." ”

Yi Dan said: "Okay, I'll tell Mr. Zheng the details." ”

So, Yi Dan and Pi Kaiyuan, you and I told Zheng Xuan the details of the whole thing one by one.

After listening to this, Zheng Xuan said: "Well, I know, the crux of the problem is the well in the backyard of the villa. If the well can't be passed, then the inside and the outside can't be combined, and the impregnable Cape Villa will be captured in one fell swoop. ”

Pi Kaiyuan said: "That's right, but the wellhead is blocked by a boulder." I also asked Mr. Zheng to find a way to move the boulder away. ”

Zheng Xuan asked, "How big is the boulder, have you ever seen it?"

Pi Kaiyuan said: "The boulder originally stood on the slope of the backyard, wide at the top and narrow at the bottom, more than three feet high, and slightly wider. ”

Zheng Xuan said: "Well, I know, such a huge stone, I'm afraid it's not easy to blow it up." ”

Yi Dan said: "Please also ask Mr. Zheng to think of a way." ”

Zheng Xuan: "Well, you can come to the house with me first." ”

Zheng Xuan brought Yi Dan and the three into the thatched hut by the sea. There are many complete coconut shells, bamboo tubes, and gourds on the table.

The clever Yi Dan asked, "May I ask Mr. Zheng, are these utensils used to hold gunpowder?"

Zheng Xuan said: "That's right, but my gunpowder is more powerful than ordinary burning gunpowder. ”

Youming also asked, "Mr. Zheng, may I ask how to refine this more powerful gunpowder?"

Zheng Xuan only said: "You come with me." ”

So he took the three of them to another room. There was only one stove in the room, and a huge iron pot containing half a pot of muddy and yellowed muddy water.

Yi Dan asked puzzledly, "Mr. Zheng, what is this? Why does it look like a pot of yellow mud water?"

Zheng Xuan replied: "That's right, it's indeed a pot of yellow muddy water." ”

Yi Dan was dumbfounded and said, "Why are you boiling yellow mud?"

Zheng Xuan said: "After this yellow mud is boiled, it can be extracted from the fire nitrate. With that, he led the three of them to another room next to each other. He pointed to a large pile of yellow stones on the ground and said, "This is sulfur, and fire and sulfur are the main things for refining gunpowder. ”

You Ming saw a large pile of strange nuts on the table, so he asked, "Mr. Zheng, what is this, the seeds of the toon tree?"

Zheng Xuan said: "This is not toon seeds, but aristolochia, which is a necessary ingredient added to gunpowder." ”

Youming said in surprise: "Ah? It turns out that aristolochia can also be used to make gunpowder?"

Zheng Xuan said: "That's right, but these are all things that the ancestors have repeatedly explored. ”

Yi Dan looked up and saw several complete empty coconut shells hanging from the window, as well as empty crockpots and iron cylinders.

Yi Dan asked, "May I ask why these things are hanging on the windows?"

Zheng Xuan said: "These iron cylinders are filled with a mixture of sulfur and thin mud, which must be dried first, then poured in the middle of the sulfur fire and gunpowder made of aristolochia, inserted into a fuse, and then blocked with sawdust, and a piece of gunpowder for fried fish is ready." ”

Youming said: "It's that simple?"

Zheng Xuan: "It's easy to say, but every step is very exquisite. If you don't pay attention, you will catch fire. ”

Youming asked, "If you stay away from the flames, will there be a fire?"

Zheng Xuan said: "That's right, because when the skin rubs against the clothes, there will also be very small sparks, which may not be visible with the eyes, so you must always be cautious." ”

Youming asked, "Won't it, this little spark will also ignite?"

Zheng Xuan said: "Of course, so this is a very dangerous thing, don't treat it as just a fun thing." ”

Yi Dan asked, "Then Mr. Zheng, may I ask what kind of gunpowder you usually use to fry fish?"

Zheng Xuan took off a crockpot and said, "I usually use it a lot, because it has a larger opening, and I can put the fuse in it several times." After ignition, there is also enough time to seal the mouth of the can with oiled paper. Then the jar is sunk to the bottom of the sea along with a stone. The jar is coated with glutinous rice soaked in rice wine, and the fish will flock to the tank when they smell the fragrance, and then the jar will explode violently, and the surrounding fish will be blown to death and float to the surface. ”

Yi Dan said: "Since the gunpowder in this jar is so powerful, how about we go and blow up that boulder?"

Zheng Xuan waved his hand and said, "No, this is not the most powerful. From my experience over time, the harder the shell, the more force it will explode. The gunpowder made from this iron cylinder is the most powerful. ”

Yi Dan asked, "So, have you ever tried the power of iron gunpowder?"

Zheng Xuan said: "Of course there is, the fish are all fried to the point that the skin and flesh are cracked, the flesh and blood are blurred, and they are inedible." That's why I don't usually use this iron cylinder gunpowder to fry fish. ”

Yi Dan suggested: "Well, since this iron barrel gunpowder is so powerful, then let's use it, right?"

Pi Kaiyuan asked, "But, there is a problem, Mr. Zheng." ”

"What's the problem?" Zheng Xuan said.

Pi Kaiyuan said: "If you want to bring so much gunpowder underwater, how can you ensure that you don't get wet? ”

Zheng Xuan said: "I have a way to do this, you can rest assured." ”

So, Zheng Xuan asked Yi Dan and the three of them to help and put the gunpowder in dozens of big gourds into more than a dozen thick cylindrical iron cylinders. A long fuse is inserted into the gunpowder of the iron cylinder, and the mouth of the bottle is plugged with charcoal. Then take out an iron cover with a hole in the middle, pass the fuse through it, and screw the iron cap. Seeing the process of Zheng Xuan screwing the iron cap, Yi Dan saw clearly that there were spiral lines on the outer mouth of the iron cylinder. She picked up another iron lid on the table, opened it, and found that there were spiral lines inside the iron cover.

Yi Dan asked curiously, "Mr. Zheng, what's going on with this pattern?"

Zheng Xuan replied: "Oh, this is a rotating thread, which I made according to the principle that after the two hammers coincide, they can't be pulled up and down." With molten iron and mold, it is molded at one time. ”

After that, Zheng Xuan picked up a small piece of damp cloth, gently covered it on the iron cylinder, then screwed the iron cover and the iron cylinder, handed it to Yi Dan, and said, "Try to see if you can pull it out without turning." ”

Yi Dan turned out to be an iron cylinder, and he couldn't pull out the lid even if he pulled it hard. So he said again and again: "It's amazing, why is there a piece of cloth on this mouth?"

Zheng Xuan: "It must be placed, and it must be a slightly moistened cloth, to block the sparks that may occur when the iron rubs against the iron." These sparks, which cannot be seen by the eye, are likely to cause the cylinder to explode during the manufacturing process. The power of this iron explosive cartridge is too great, and if it explodes in your hand, the corpse will turn into a cloud of blood mist. ”

Yi Dan couldn't help but shudder and said, "So terrible?"

Zheng Xuan said: "Of course, this is not a joke. Fill up the gunpowder and don't move, let me get it. ”

When Youming heard this, he was so frightened that he hurriedly put down the iron cylinder in his hand gently, not daring to act rashly.

Zheng Xuan stuffed the charcoal tightly for each iron cylinder with gunpowder and fuse in turn, and then tightened the lid with a damp cloth.

He took a large bundle of fuses and oiled paper and said, "Take all these iron cylinders, and let's go to Cape Villa." ”

The three of them took the iron cylinder full of gunpowder and walked out of the hut. Zheng Xuan stood on the beach, put his hand in his mouth, and whistled loudly at the sea. After a while, I saw a large group of dolphins swimming over.

Yi Dan and You Ming were both amazed, they didn't expect such a cute dolphin to really understand the call of their master, and they all gathered at this time.

Zheng Xuan said to the dolphins, "You guys come with me." ”

Everyone walked along the beach and headed west. The dolphins also follow the sea outside the beach and follow everyone all the way to the west. Sometimes they frolic and sometimes jump out of the water and squeak, like lively and cute elves. Occasionally, a dolphin just frolicked and fell behind, and as soon as Zheng Xuan waved his hand on the shore, the dolphin that fell behind would immediately rush up and continue to move forward after the other dolphins.

Yi Dan and his brother led the horses, walked on the coast, and looked into the sea from time to time, and the two of them loved those lovely elves in the sea. (To be continued.) )
