Yuan Fang seemed to understand something, and humbly asked: "Hongyi, if you have any ideas, just say it." ”

Hongyi thought for a while, got up and ran out in Yuan Fang's astonishment, and after a while, he came in with a dry straw pole: "This is what I found from the stable." ”

Yuan Fang scratched his head and asked, "What are you doing with this thing?" ”

Hongyi took a few breaths and said, "Brother, gunpowder is like flour, it can be packed in a bag or in a bamboo tube, there is no bamboo tube in this place, so I'll use this instead." ”

Yuan Fang said very sincerely: "Go on." ”

Hongyi paused: "I used to follow my godmother to do business with pirates in the eastern seas when I saw pirates put wheat flour in bamboo tubes for preservation, I was very puzzled at the time, and then godmothers told me that this is in addition to the pirates in order to prevent wheat flour from getting damp and moldy, and there is also a role that the weight of wheat flour in each bamboo tube is the same, in your words, well, it should be space, volume, weight or something." ”

Yuan Fang thought for a while and said, "Are you saying that the space is the same, the volume of the object is the same, and the weight is the same?" ”

Red-clothed nodded: "Almost." ”

Yuan Fang frowned and said, "No, the bamboo tube grows naturally, and it is impossible for the space in each bamboo tube to be the same." ”

The red clothes said disdainfully: "I'm just making an analogy, what are you doing so seriously? ”

Yuan Fang spread his hands and said: "This thing is related to human life, how can you do it if you are not cautious and rigorous?" ”

Hongyi didn't talk nonsense, grabbed a handful of gunpowder and poured it into the hollow straw stick, Yuan Fang was startled: "What are you doing?" Don't mess around and watch out for explosions. ”

Hongyi ignored Yuan Fang: "You'll know later." ”

After a while, the straw stick more than ten centimeters long and half a finger thick was filled with gunpowder, and the red-clothed straw stick stood up on the table and said, "This straw stick is about the same thickness up and down, so the gunpowder inside should be almost even, right?" ”

Yuan Fang looked at the straw stick filled with gunpowder and was silent, nodded for a long time and said, "Well, it should be like this, but won't the gunpowder explode if it is pressed so hard?" ”

The red-clothed booth said, "Then I can't take care of it." ”

Yuan Fang proposed: "Why don't we try?" ”

Red-clothed said excitedly, "Okay, try it." ”

Just that big straw stick, there is so much gunpowder in it, even if it explodes, the destructive power will not be too great, but Yuan Fang is still very careful, let Hongyi stay in the house, he went out alone with a straw stick, first set up a shield, buckle the helmet, and when everything is ready, he will take a torch and carefully light the straw stick.

The place above the straw stick where there is no gunpowder is ignited, and gradually burns downward, and when the flame spreads to the position of the gunpowder, the gunpowder is ignited, and there is no explosion, and the smoke rises from the violently burning fire.

The red-clothed man who was hiding in the room and lying on the window and watching shouted in surprise: "Brother, brother, look, there is no explosion, and the burning is much more stable than your fuse." ”

Yuan Fang, who was hiding behind the shield, poked his head out to look at the steadily burning straw stick on the stone, opened his mouth in surprise, and as soon as his hand was loosened, the heavy shield fell to the ground with a bang, bringing a strong wind to blow away the thick smoke of gunpowder.

Soon, the gunpowder burned out, and the straw sticks were completely burned to fly ashes, leaving only faint marks on the stones.

Yuan Fang scratched his head in disbelief and said, "Could it be that the gunpowder will not explode if it is compacted?" Or is it because the straw sticks are not airtight enough? ”

The red coat came out of the house and said triumphantly, "How is it?" I'm better than yours, right? ”

Yuan Fang nodded heavily: "Well, Hongyi is really smart, much stronger than me." ”

Yuan Fang is not a compliment, this is true, Hongyi can think of this method without knowing the characteristics of gunpowder is indeed commendable, although Yuan Fang knows that she also crossed the river by mistake with a stone, but the result is good, then it is worthy of praise.

The red clothes became more and more proud, and his little head was raised high, like a triumphant general or a victorious rooster.

Yuan Fang stretched out his hand and rubbed the hair of the red cloth: "Let's go, let's go find some straw sticks and come back for experiments." ”

Hongyi dissatisfiedly discharged Yuan Fang's magic grasp, combed his hair with his fingers and said, "It's so annoying, it messed up my hair." After speaking, he caught up with Yuan Fang and went straight to the stable.

Long Roundabout is not too big, under normal circumstances, no one rides horses, and there is time to prepare horses to run to the destination, but there are still a lot of jobs on the island that require horse-drawn carriages, such as transporting some heavier things or something, so some horses are raised on Long Roundabout.

Yuan Fang and Redyi came to the stable in a hurry, and several guards still followed dutifully, without waiting for Yuan Fang to ask, Redyi pointed to the wooden house next to the stable and said, "There, that's where the forage is placed." Yuan Fang didn't say a word, and followed the red clothes into it.

In the wooden house, two navy soldiers who raised horses were cutting grass with guillotines, and they were startled when they saw two guys in heavy armor rushing in, and subconsciously went to get the war knives that were put aside, but when they saw a few female soldiers who came in later, they were relieved.

Yuan Fang and the monkey in red dragged down a bundle of straw and directly kicked and rummaged, just like looking for insects and hens.

The two naval soldiers looked at each other blankly for a while, and one of them asked curiously, "Lord Yuan, Your Royal Highness the Princess, who are you?" ”

Yuan Fangtou didn't reply and said, "It's okay, find something, by the way, you guys also come to help." Two Navy soldiers leaned in.

Yuan Fang turned back to the guards behind him and said, "Come and help, find this kind of grass stalk, it should be hollow, the longer the better." ”

For more than half an hour, Yuan Fang held a straw in his hand and hummed a small song side by side with the red clothes side by side, and the guards behind him each carried a bundle of straw on their shoulders.

Back at the stone house, Yuan Fang did not delay in starting the experiment, first picked ten straws, cut the hollow part into equal parts of a foot in length, and then filled the gunpowder with Hongyi, and then added it until the space inside the straw stick was completely filled with gunpowder.

Because it was not sure whether this thing would explode or not, Yuan Fang still let Hongyi hide in the house, and he went out to experiment alone, the experiment went very smoothly, and it was very stable without burning with the gunpowder stick, which surprised Yuan Fang.

Next, Yuan Fang spent an afternoon with Hongyi, as well as the guards responsible for protecting him, and then made more gunpowder sticks, Yuan Fang also kept trying, physically squeezing the gunpowder in the straw sticks, that is, poking it in with thin branches, and then igniting it, calculating, as a result, Yuan Fang was pleasantly surprised to find that the compacted gunpowder burned more steadily.

With this conclusion, Yuan Fang's eyes suddenly brightened, and then, Yuan Fang gave up the straw and switched to other containers, such as glass tubes, such as iron pipes.
