This loud bang blew everyone in the house out.

Except for Ah Mei, who personally participated in the production of firecrackers, her face was quite calm, and even the look on Huang Yueying's face was shocked.

Then everyone watched as Feng Junhou got up from the ground in embarrassment.

"It's ...... Spring thunder? ”

Huang Yueying walked over, her eyes were full of confusion, and she asked.

She sat peacefully in the room, not looking outside, not knowing what was happening.

The firecrackers were made by Feng Yong and Amei themselves, except for the two of them, the rest of the people in the venue had only heard that Feng Junhou had made something new, but they didn't expect such a sound.

"No, it's just a firecracker."

Feng Yong hurriedly explained.

Huang Yueying looked at Guan Ji, who was retracting her defensive posture, and then looked around, but she didn't see bamboo, only some scattered red confetti.

"Firecrackers? What kind of firecrackers make such a sound? ”

"Uh, this firecracker is not the usual firecracker, it's ......"

Feng Yong turned around and was about to point it out to Huang Yueying.

How did he know that under this look, he was frightened: "You put it down for me!" ”

Zhang Xingyi saw the whole process, and actually took a firecracker while Feng Yong was talking to Huang Yueying.

At this time, he was learning from Feng Yong's appearance at the beginning, stretching out the incense from afar, wanting to point the lead.

Fragrant?

Where's my incense? How did it end up in the hands of this woman?

Feng Yong realized that his hands were empty.

This loud shout made Zhang Xingyi turn his head in fright, and at the same time his hand shook.

"Woohoo......"

"Run, run!"

Feng Yong rushed over, picked up Zhang Xingyi and ran.

Guan Ji had experience this time, and escorted Huang Yueying to take a few steps back.

Fortunately, when making firecrackers, the lead was deliberately lengthened because of safety.

A flash of fire.

"Bang!"

Confetti flies.

Ah Mei and Li Mu held the child, but they didn't get the order to come over, so they could only watch from a distance in the house.

"Wow!"

The child was not able to cover his ears in time this time, and he was so frightened that he cried all of a sudden.

Guan Ji heard the child's cry, glared at Feng Yong fiercely, and walked over quickly to see the child.

Feng Yong was a little inexplicable, this was not done by me.

It wasn't until someone poked him in his waist that he realized that he had been protecting Zhang Xingyi and holding her half-in his arms.

Feng Yong hurriedly let go of his hand.

Zhang Xingyi carried everyone behind his back, raised his face, his eyes bent into crescents, and quietly pinched his waist, and then parted.

Feng Junhou was a thief and glanced at Huang Yueying next to him.

Huang Yueying seemed to be smiling, didn't speak, and turned back to look at the child.

Feng Yong followed step by step, only to see that Ah Worm in Li Mu's arms was crying lively, but the Shuangshuang in Ah Mei's arms was open with "ahh

Guan Ji pressed the worm from Li Mu's hand and patted it a few times.

Ah Worm was coaxed by his mother, and then he quieted down.

"Put the child in the back room, and it will be quiet. The ancestors of the Feng family have also seen the child, so they will not blame it. ”

Huang Yueying is still experienced in handling things, and she commanded.

After a small episode, everyone's attention finally turned to firecrackers.

"Bring that thing to me!"

The first one who couldn't hold back was Huang Yueying.

Zhang Xingyi rushed over and brought another firecracker.

Huang Yueying's eyes were burning and shining, and she took this thing and looked at it over and over.

Finally, he handed it to Zhang Xingyi, "Go, burn a few more and try it." ”

Zhang Xing remembered the order and ran away excitedly.

"Run away immediately when you ignite, stay safe!"

Feng Yong reminded loudly behind him.

Guan Ji said: "I'll go and watch her!" ”

And then ran away too.

Facing a group of women with violent genes, Feng Junhou has more than enough heart but not enough strength.

Listening to the thumping sound, sparks flew everywhere, Huang Yueying's eyes also flashed with sparks, and her face was flushed.

I don't know if it was frozen or stimulated by the sparks and loud noise.

She asked in a low voice, "These kinds of objects are just small appearances, but they have such power." You say, if you make it bigger......"

Feng Junhou made firecrackers, knowing that there would be such a day, but he didn't expect it to come so soon.

Just by exploding, someone asked him that.

"Madam, this one is bigger, as soon as people get close, they will be injured if they don't die."

"Really?!"

Huang Yueying was not surprised.

Feng Yong shrugged, "Naturally, it's true, but it doesn't have long eyes, and it will not only kill others, but also kill yourself." ”

"And this thing is easy to get damp, and it's useless when it gets wet."

"Of course, if there is a way to put it under the city gate, it can also be blown open."

Huang Yueying's eyes lit up again.

"It's just that the amount needed is a bit large, with the current situation of Dahan, if you save for a few years, you should be able to save the amount to blow up the city gate."

"However, if the engineering battalion is smashed with a stone throwing truck, even the strongest city in the world will only be smashed in two or three months at most."

Huang Yueying: ......

In the production of black powder, the source of charcoal is not a problem, nor is the source of nitrate.

The source of sulphur is a big problem.

Nitrate and sulfur purification is a big problem.

With the continuous development of Nanzhong, sporadic small sulfur mines have been discovered.

But it doesn't help.

Because the road conditions are so bad.

And the amount is too small to be used for large-scale mining.

Black powder is not the gunpowder produced industrially in later generations, its power is very small, you use it to blow up a small city, then there is no need.

Because the walls of the small city are basically very low, you can climb over them with a ladder.

If the walls are dilapidated, people can climb over them without even using tools.

That's why when a big city is lost, the surrounding small cities surrender.

And you use it to blow up a big city, and you want to get the power of a pack of dynamite in the future, and exchange it for black powder, which is calculated in large trucks.

This is also when nitrate and sulfur can improve purity.

But with the current level of craftsmanship, if you want to raise the purity of these two to a satisfactory level, Feng Junhou does not have any illusions.

It is better to directly use the counterweight stone throwing cart to smash, which is much more convenient than black powder.

The production is not enough, the purity is not enough, except for being used to make fireworks and play with firecrackers, there is no use.

It is always said that the ancients invented black powder, which can only be used to play with fireworks, and they are not enterprising, and in the end they were overtaken by the West, which is really angry.

Now Feng Yong himself realized that he could only not make progress.

He finally realized that he had neglected a fundamental problem: that the West had carried out gunpowder and blown it up all over the world, and that was supported by the industrial system.

And Feng Yong is now in the stage of quietly developing the handicraft industry.

The garbage power of black powder, the garbage production of steel, and the quality of garbage, and the level of garbage made by the process......

In the end, it is estimated that it is not as good as a firearm at the end of the Ming Dynasty, it is not good to blow up the enemy, but it is refreshing to blow up and hurt your own people, what is the use of this thing?

Huang Yueying looked at the two girls who were jumping over to avoid the firecrackers, and her face showed disappointment: "I see, it seems that I am thinking too much." ”

Feng Yong was a little surprised, he didn't expect Huang Yueying to accept his statement so quickly.

"Thank you, Madame, for your trust."

If Huang Yueying didn't believe in himself and had to try it himself, then he would have to worry.

In case the operation is not standardized, if something goes wrong, Zhuge Old Demon can kill himself alive.

Huang Yueying smiled.

"This thing is something from your master's sect, right? You can say so much with just one mention, and you must have already made a conclusion in your school. ”

"If you can have enough of it, you can use it once in a while."

Feng Yong said in conclusion.

If there is an opportunity to pile tons of black powder under the enemy's city, or pile it up at a specific location, and then lure the enemy over and bombard it, it is also a good idea.
