Chapter 208: Good things come to your door

The advantages and disadvantages are so obvious that it is difficult for them to be not curious. Chen Wanrong saw their expressions and kept nodding: "As I expected, they became interested when they heard it."

Chen Wanrong continued: "Firecrackers have one disadvantage compared to firecrackers, that is, they are too dangerous, because firecrackers are made of gunpowder, and if one is not good, they will explode and hurt people."

Children in modern society are playing with firecrackers and hurting them too many things. Although they are not boys, their understanding of firecrackers is not much different from that of boys. Chen Wanrong has to explain it in advance to avoid unnecessary accidents.

"Made of gunpowder?" The students were even more excited when they heard this.

Who doesn’t know that this great victory in Tubo is because of artillery? Artillery uses gunpowder. For the students, gunpowder is a sacred existence. They have long wanted to see it. But they have never had the chance to come into contact with it these days when they came to the military weapon surveillance. How could they not be surprised?

The students will become good workers in the future, but they cannot get in touch with the core secret of gunpowder so early. This is Chen Wanrong's arrangement.

Chen Wanrong nodded and said, "That's right! It's made of gunpowder."

"General Chen, what should I do?" Gao Jian was most anxious, staring at Chen Wanrong with his eyes wide open.

"General Chen, tell us quickly." The students urged them all over the place.

It is their wish to contact gunpowder. Now, not only can they get access to gunpowder, but also such novel things. How can they not be anxious? Zheng Wanru flashed her leisurely eyes at Chen Wanrong, meaning that you wouldn't tell me about such fun things. Your brother-in-law is too inviting enough.

Chen Wanrong had not spoken yet, but saw Kou Yibing, Liu Huaide, Cao Zhixiong and others coming in one after another, looking at Chen Wanrong in surprise. They all knew that Chen Wanrong had a deep attainment in chemistry, but Chen Wanrong was too busy and had no chance to explain. They had long been looking forward to listening to the true face of chemical engineering. I heard that Chen Wanrong had tried to squeeze Ye Tianheng's class, so how could they come and see it?

"Come and listen to the way of firecrackers." Ye Tianheng was the first to spread the news: "Firecrackers are made of gunpowder, which has two benefits compared to firecrackers. One is that the sound is crisp and loud, and the other is that it is convenient. Even if the guests come to the door, it is still too late."

Learn and sell now, it seems to be similar.

"General Chen, tell me quickly!" When everyone heard Ye Tianheng tell the benefits of firecrackers, they could not bear it and urged them in unison.

Chen Wanrong nodded and said, "Before I'll tell you a good news first. I just went to the palace and the emperor said that our military weapon supervisor has made a lot of contributions in this great victory in Tubo. The emperor wants to give the good craftsmen involved in the manufacturing of artillery!"

"The Emperor's Holy Spirit!" This is a great thing. When everyone heard this, they were overjoyed and praised the wise wisdom of Ruizong in unison.

When the students heard this, their eyes shone. It was true that the future of the military weapon surveillance is no worse than that of the Imperial College. As long as they make good things, they will have titles. They wished that the Tang Dynasty would fight every year, so they would make more weapons.

Chen Wanrong couldn't help but feel relieved when he saw the reactions of the students!

When they calmed down, Chen Wanrong continued, "Of course, the emperor sent us another thing, which was to make firecrackers. The soldiers who returned from the war were about to return to Chang'an. Our military weapon supervisor was going to build firecrackers and set them off when we welcomed them. Do you have the confidence to do it well?"

"Yes!" has only one word, but the sound shook the sky.

Not only were Ye Tianheng and other good craftsmen yelling, but even the students were yelling loudly.

The battle of Tubo boosted the morale of the people of the Tang Dynasty and was worth it for the soldiers. Who would not want to?

Ye Tianheng and the others hurriedly found a seat to sit down, and quietly waited for Chen Wanrong to start the lecture. Chen Wanrong picked up a piece of charcoal and drew a cylinder on the wooden board, with a black thread on the cylinder: "This is firecracker!"

"Is this firecrackers? That's so simple?" Everyone couldn't believe that such a magical firecracker was so simple.

After the gunpowder is ignited, it burns quickly, producing a large amount of gas, and then explodes. Whether it is a paper tube or a shell, it doesn't matter, it just needs to be sealed to explode.

"Isn't it easy? The firecracker is just a paper tube, with mud seals underneath, mud seals on top, and gunpowder in the middle. This black line is the fuse. It's that simple, don't think it's so difficult to make a cannon." Chen Wanrong pointed to the painting and explained to them.

"Oh!" A sigh sounded, very disappointed.

Kou Yibing smiled and said, "General Chen, I thought it was really like making artillery, and I was going to be busy again. I didn't expect it to be so simple, so we can do it with our eyes closed."

"That's it!" Ye Tianheng and the others agreed in unison.

"We'll do it now!" Cao Zhixiong couldn't help it.

Chen Wanrong waved his hand and said, "This is just a matter of making one. You have to string together firecrackers to set it off." He drew a schematic diagram of firecrackers and said, "A little here must be loud..."

Ye Tianheng took the conversation and said, "It's not difficult, is it just a fuse? I've already figured out a solution."

"I thought of it too!" Dozens of good workers said in unison, very excited.

Firecrackers are indeed not difficult. They are far inferior to artillery. They can even make artillery, but they can’t make firecrackers? The good workers are experienced and there is no problem thinking of him with ten or eight methods.

"Okay! Let's try it now." Chen Wanrong believed that what they were telling the truth.

With a burst of cheers, everyone rushed out of the house and asked people to bring gunpowder, paper, and glue.

When trying to do it, you must make it bigger, let them practice it well, and then make it smaller. Chen Wanrong said that he put Ye Tianheng’s crutches, put the paper on the table, brushed a layer of glue on it, and rolled it into a cylinder shape after a few strokes. The thickness was exactly the same as Chen Wanrong’s intention.

Everyone started to do it, and in a short while, hundreds of paper tubes were prepared. They asked people to raise the fire and put the paper tubes to the fire to bake. After a burst of white smoke, they were dried.

There is some clay in the military weapon surveillance, so there is no need to mix the mud anymore. Just use it directly. Seal it below, pour some gunpowder in, seal it up, and install a fuse. The firecrackers are done. You just need to dry it and you can try it.

Ye Tianheng and the others were curious, and the students thought it was novel and they all started to do it. One person, one or hundreds of them were arranged neatly.

Now, I dare not use fire to bake it. If Mars splashes on the fuse, it will cause trouble. I can only put it in the open space and let the sun dry. This is too novel, and everyone does not do anything else. They circle a large circle, three layers inside and three layers outside, staring at the firecrackers.

Time passed silently, and everyone kept rumbling and finally got it done.

"Try it quickly!" Ye Tianheng picked up the firecrackers he made, put them in a corner, took out the fire and lit them, and ran to the side as if he was flying. He usually needed a crutch when walking, but in this case, he didn't use crutches, and ran as if he was flying.

"Bang!" Amid everyone's expectations, a shocking sound rang.

Ye Tianheng and other good workers were used to hearing the sound of cannons, but they had no reaction. However, the students were shocked. Many people called "Oh my God" and looked surprised.

The firecrackers were made larger and the gunpowder was filled with more gunpowder, so the sound was naturally much louder. Everyone cheered in unison: "Really! It's much crisper and louder than the firecrackers, which is easier to do."

Some students reacted quickly: "General Chen, what would happen if this thing was sold on the market?"

"Is that need to be said? The door must be blocked!" Cao Zhixiong's pitch-to-door was raised.

This is inevitable!

Ye Tianheng's experiment was successful, but the others were not willing to fall behind. They set off firecrackers and ignited the leads. The sound of banging sound was very lively. It was not until after a while that they stopped.

Chen Wanrong counted and found that there were many squibs, and there were actually as many as 40 or 50. Chen Wanrong was satisfied with the first time he tried it and got such a result.

The dense explosions made people feel comfortable to listen to, and the students were extremely happy, and Zhihuzhe was talking nonstop.

Ye Tianheng pulled Chen Wanrong's arm and said, "My friend, this firecracker cannot be done like this. Doing this is too difficult and inefficient. We have to use machines to do it."

Modern firecrackers are made of machines, and Chen Wanrong also thought about this beautiful thing, but the Tang Dynasty could not have machines, so I could only think about it. Ye Tianheng's words surprised Chen Wanrong and asked, "Master Ye, do you have a way?"

"I have a little idea. Let's go, and the house said." Ye Tianheng grabbed Chen Wanrong's arm and entered the house with a crowd, and drew it on the wooden board: "My friend, I have thought about it. It's not difficult to make this firecracker with a machine. If we roll this paper tube with our hands, it is difficult to grasp the thickness, and the other is that it is different from the elasticity and tightness, and there are a lot of waste, so it will be different when using the machine."

The disadvantage of manual work is here, the question is how to use the machine?

Just as Chen Wanrong was surprised, Ye Tianheng continued to say, "This machine is not difficult. There are still some empty spaces on the machine tool, so you can use it. There is no need to dig a trenches. You only need to make a few brackets."

While explaining and drawing, a simple machine production diagram was drawn. Chen Wanrong looked at it, his eyes widened, Zhang Ba could stuff an egg into it, his face was shining with a shining glory, and a bear hug hugged Ye Tianheng in his arms, and laughed: "Master Ye, you can really think about it! This matter will be done!"

What he drew was very simple, just packing the paper roll, then driving it with hydraulic power, and moving it slowly. At the other end, the same device was used to roll the paper into a barrel. In between, he also designed a simple glue brushing device, which is a glue bucket on the top and a large brush below. The glue flowed down from the holes and applied to the paper after the brush.

This brush is small on the top and large on the bottom, similar to a broom. When the glue flows down, it will definitely be applied to paper. Not only is it easier to use manual work, but it is much more even.

As for the paper collection, he also designed a scale, which is to roll a long piece of paper tube at a time and then cut it off. In this way, the height of the paper tube is not much different.

This design is naturally not comparable to modern machines, but its efficiency is much higher, and Chen Wanrong highly appreciates his bright reaction.

Kou Yibing and the others saw it, were happy in their hearts, and said with a smile: "Brother Ye, it's really amazing to have you!" His thumbs were raised to the sky.

Ye Tianheng smiled and said, "If you want to do this well, you have to do one thing in advance. That is, the paper we buy must be thick and thick, and the paper mill must be rolled into a tube."

This matter is not difficult, you just need to tell the paper shop, and Liu Huaide immediately sent someone to do it. Chen Wanrong and the others hurried to the machine tool workshop. As Ye Tianheng said, there were still a few empty spaces there, and the power was ready-made. You only need to install it to make firecrackers.

Chen Wanrong estimated that when he was using it, there were enough firecrackers, which was a great relief.

Once again, I learned about the wisdom of the Tang people and strengthened Chen Wanrong's original intention. He pointed out the direction and realized it by Ye Tianheng and others. Combining modern minds with the wisdom of the Tang people will surely write a brilliant chapter!

The next thing was to discuss some details. The technical details were the most cumbersome. The discussion was not until dark for a while before the discussion was over. Chen Wanrong left Ye Tianheng and the others and went back to Zheng Mansion.

As soon as he entered Zheng Mansion, he greeted Zheng Qing. Today's Zheng Qing is a little different from the past. She pursed her lips, and she was both happy and shy, as if she had something to say to Chen Wanrong, but it was difficult to speak.

"What's wrong with you?" Chen Wanrong asked curiously.

Zheng Qing turned her head: "It's okay!"

"It's okay? It's okay, can you do this?" Chen Wanrong really couldn't figure it out.

"You are just back now, and your parents are waiting for you." Zheng Qing complained slightly.

Chen Wanrong held Yiren's hand and found that her hand was a little cold, making her even more strange: "I have something to do today and I'm back a little late. You're not angry, are you?"

"How could he get angry?" Zheng Qing was still as generous as before, but the words followed made Chen Wanrong unthinkable: "Except today!"

Sometimes, Chen Wanrong came back later than today, and Zheng Qing never complained. After hearing this, Chen Wanrong knew that something must be happening today, so he hurried into the house and saw Zheng Jianqiu and Chen Laoshi, who looked happy, were happier than beggars who picked up the ingot.

"Wanrong, why are you back? You're going to tell you something big." Chen Laoshi complained as soon as he saw Chen Wanrong.

Chen Wangshi gave him a blank look: "Old man, what are you complaining about? Isn't Wanrong doing big things?"

"Dad, mom, what do you have to tell me?" Chen Wanrong couldn't help but be surprised.

Zheng Qing blushed and she went out like flying. If she had been in the past, she would have been stuck with Chen Wanrong. Today's behavior was too abnormal.

Zheng Jianqiu smiled and gave Chen Wanrong a cup of tea and said, "This is what the girl cooked for you. Wanrong, you should drink a little tea first and take a break, and it's not too late for us to tell you."

It was still the father-in-law who felt sorry for someone. Chen Wanrong responded and took the teacup and drank it. He knew it was cooked by Zheng Qing. The taste was different. He smiled and said, "Father-in-law, you can say it."

Zheng Jianqiu nodded and said, "Wanrong, you are not young anymore. The girl has long been married. However, she has a high vision. Until you appear, she is all her thoughts on you. Now, you are successful and famous. Who doesn't know the name of the artillery general? It's her blessing to marry you. You have been engaged for a while. We are discussing and find some time to get your affairs done!"

It turned out to be about the marriage, Chen Wanrong was overjoyed and said, "That's good!"

Chen Wanrong's wish was to meet and fall in love with Yiren for so long, and spend his whole life with Yiren. He smiled happily and his eyes were narrowed together.

Zheng Zhou took over the conversation and said, "Wanrong, you know your own affairs best. You were busy some time ago, so we didn't mention it. We originally thought that you always had time to finish your work, but you were busy all the time and you were busy but not too far. Now, the weather is already cold and the end of the year is not far away. If you don't do it, you don't know how long it will take to do it. Wanrong, do you think, when is the better time to choose this time?"

"Wanrong, you make a decision quickly! When you decide, we can find someone to choose a good day!" Chen Houshi touched his face, which was a bit hot: "Wanrong, you are old, it's time to have children, and your father is still waiting to hold his grandson."
