Chapter 269 What are saltpeter and sulfur?

"Yes, the food in Yuquanlou is expensive, and we are reluctant to go."

"So that's how it is." Nangong Anshan said: "You are my apprentices, if you want to eat something delicious in the future, you can come to my house. Anyway, there are many people in my house, and I have to cook a lot of food every day. It's just a matter of adding a few pairs of chopsticks, don't be polite."

The four expressed gratitude: "Thank you, Master."

Nangong Anshan said: "Eat quickly, it will get cold later, it won't taste good."

"OK."

Nangong Anshan was halfway through eating, and when she saw that the wild pork was cooked, she put it in front of Zitian and Ziyun for them to eat.

Feng Yang filled a bowl of tomato and egg soup, and after taking a sip, he was surprised, "This taste is really good, sour, it suits my taste."

The other three had eaten and hurriedly tried it too.

"It's delicious, it's really delicious."

“This is the best soup I’ve ever had.”

"Yes, yes."

Nangong Anshan said with a smile: "Drink it all if it tastes good. If you can't finish it, it's a waste."

The four nodded and drank quickly.

After everyone finished eating, the four of them said they would help wash the dishes and boil the water, so she didn't force them and let them do the washing.

After they washed everything, Nangong Anshan borrowed a water tank to put all those things into the space.

After everyone rested for a while, Nangong Anshan said: "Okay, let's start. The formula ratio of explosives is very strict. If you make a mistake, it is very likely to fail, so everyone must score 12 points." Spirit, do you understand?"

"understood."

Nangong Anshan ordered the four people to work together.

After the four of them finished handling all the necessary things, she began to teach them how to configure explosives.

Here she has prepared a lot of bamboo in advance, just take it and use it.

After a while, Nangong Anshan looked at the bundle of explosives in front of her and said seriously, "This is a bundle of small explosives. I'll show you how powerful it is."

After speaking, she walked to the distance, lit the fuse, and quickly threw the explosives out.

With a bang, the explosives exploded smoothly, and the place was completely blackened.

Feng Yang, Feng Yuan, Feng An, and Feng Shen stepped forward to take a look, and saw that a big pit with a diameter of two meters and a depth of more than one meter had been blown out in front of them.

The four returned to Nangong Anshan's side.

Feng Yang said excitedly: "Master, you are really amazing."

Feng Yuan said: "If Li Wang's fief has this explosive, it is estimated that there will be no fear of enemy invasion in the future.

Feng An said: "Yes, if the enemy knows that we have this, they will definitely be frightened."

Feng Shen said: "In the future, the people here will be less casualties."

Nangong Anshan was looked at excitedly by the four handsome guys, and she was also a little embarrassed, and said with a smile: "Okay, I taught you while I was doing it just now, have you all memorized the process?"

"I remember them all."

"Well, you all go and try it out. If you are not sure, ask me again. But for the first time you do it, you must keep the lead wire longer. Don't hold it with your hands like I did later. You still have to put it on the ground and light it a few times. Otherwise, if you fail, your hands will be blown off."

"Understood, Master."

Feng Yang, Feng Yuan, Feng An, and Feng Shen went to make explosives, and Nangong Anshan was also watching.

After a long while, the four of them were ready.

Nangong Anshan tried one by one.

It was the same as what she said just now, what the four of them did was first put the explosives on the ground, and then Nangong Anshan went to ignite the fuse in person.

The first one exploded smoothly.

The second one also exploded smoothly.

The third and fourth ones also exploded smoothly.

Feng Yang, Feng Yuan, Feng An, and Feng Shen were suddenly excited. They didn't expect them to learn it so quickly.

Nangong Anshan nodded secretly, she is indeed the smartest person under A Xu, and she learned it the first time.

"Don't be too happy too early. This is a small explosive. If you can learn all of them next, and you can make no mistakes in every test explosion, you can go out smoothly."

The four said at the same time: "Yes, Master."

So this afternoon, everyone has been experimenting with various doses of explosives, and there are explosions nearby from time to time.

When it was getting dark, Nangong Anshan said: "This time, let's make a large dose together and see how big a hole we can blow up."

The four said at the same time: "Yes, Master."

The five people quickly made up the explosives and placed them in an open space.

Nangong Anshan left the fuse very long this time. As soon as she took out the torch, Feng Yang said: "Master, the power this time must be very powerful. Let me do it. We also need to learn how to light the fuse."

"That's true." Nangong Anshan handed the torch to him, "Be careful, we'll wait for you at a distance first."

"OK."

After Nangong Anshan ran to a safe place, Feng Yang started to light the fuse, and then quickly ran to a safe place.

With a bang, a violent explosion sounded quickly.

The power this time was extraordinary, and the snow on the trees within a radius of 400 meters was shaken to the ground.

Nangong Anshan and the disciples were also covered in snow.

After confirming that the explosion site was safe, Nangong Anshan led the disciples forward, looked at the huge pit in front of him, and said with a smile: "Today is not bad luck, every test explosion has been successful."

Feng Yang said: "This is all taught by you, Master."

At first, when they knew that they were going to worship a ten-year-old girl as their master, they felt a little disdainful, but now they are completely convinced.

Their master is a god-man, who is currently their most admired person.

Nangong Anshan said: "However, this does not mean that you have fully mastered the formula of explosives, so tomorrow you have to continue to learn for a day, and then test you on the ratio of various raw materials, so that I can let you become teachers with confidence."

The four of them nodded, "Yes, they all listen to Master."

night

Feng Yang, Feng Yuan, Feng An, Feng Shen returned to the Li Palace.

Dugu Huanxu asked: "How are you learning? Have you mastered it?"

Feng Yang nodded, and repeated what Nangong Anshan said.

Dugu Huanxu said: "What Ah Shan said is not unreasonable. Such a dangerous thing should be mastered carefully. Tomorrow you will learn from her for another day."

Feng Yang said: "Yes, Your Highness."

Dugu Huanxu asked again: "How is the explosive made?"

Feng Yang said: "It is made by mixing saltpeter, sulfur, charcoal, etc. according to a certain ratio."

"Then what are saltpeter and sulfur?"
