"Yes, the food at Yuquan Tower is expensive, so we can't bear to go there."

"That's it." Nangong Anshan said: "You are my apprentices. If you want to eat something delicious in the future, come to my house. There are many people in my house anyway, and I have to make a lot of food every day. You can come here."

It’s just a matter of adding a few pairs of chopsticks, so don’t be polite.”

The four of them looked grateful and said, "Thank you, Master."

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

"OK."

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

Feng Yang filled a bowl of tomato and egg soup. After taking a sip, he was surprised, "This tastes really good. It's sour and sour. It just suits my taste."

The other three people finished eating and hurriedly tried it.

“It tastes great. It tastes really good.”

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

"That's right, that's right."

Nangong Anshan smiled and said: "If it tastes good, just drink it all. If you don't finish it, the rest will be wasted."

The four of them nodded and drank quickly.

After everyone had finished eating, the four of them helped wash the dishes no matter what, and even boiled water on their own initiative. She did not force them to do so and allowed them to wash the dishes.

After they had washed everything, Nangong Anshan used the water tank to put all the things into the space.

After everyone rested for a while, Nangong Anshan said: "Okay, let's get started. The formula ratio of explosives is very strict. If you make a mistake, it is very likely to fail, so everyone must be careful.

Spirit, do you understand?"

"knew."

Nangong Anshan ordered the four people to divide the work and cooperate.

After the four of them had taken care of everything they needed, she began to teach them how to prepare explosives.

She has prepared a lot of bamboo here in advance, just bring it over and use it.

After a while, Nangong Anshan looked at the bundle of explosives in front of her and said seriously: "This is just a bundle of small explosives. Let me test its power for you."

After saying that, she walked far away, lit the fuse, and quickly threw the explosive out.

With a bang, the explosive exploded smoothly and turned the entire place black.

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

The four of them returned to Nangong Anshan.

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

Feng Yuan said: "If the Liwang fiefdom had this explosive, it would probably not be afraid of enemy invasion in the future.

Feng An said: "Yes, if the enemy knew that we had this, they would definitely be scared out of their wits."

Feng Shen said: "In the future, our people here will have fewer casualties."

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

"I remember everything."

"Okay, you all go try it out. If you are unsure about anything, come back and ask me. But the first time you do it, the lead must be longer. Don't be like me later, holding it with your hands and holding it in front.

You still have to put it on the ground and light it on fire a few times. Otherwise, if you fail, your hands will be blown off."

"I understand, Master."

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

After a while, the four of them were ready.

Nangong Anshan tried one by one.

Just as she said just now, what the four of them did was first put the explosives on the ground, and then Nangong Anshan personally lit the fuse.

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 immediately excited. They didn't expect them to learn it so quickly.

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

"Don't be too happy too early. This is a small explosive. If you can all learn it next and make sure there are no mistakes in every test explosion, then you can successfully start the mission."

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

Therefore, throughout the afternoon, everyone has been testing various doses of explosives, and explosions were heard nearby from time to time.

When it was almost dark, Nangong Anshan said: "This time we will make the largest dose together to see how big a hole we can make."

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

The five people quickly prepared 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 fuse, Feng Yang said: "Master, the power this time will definitely be great. It's up to me to do it. We also have to learn how to light the fuse."

"That's true." Nangong Anshan handed the fire certificate to him, "Be careful, we will wait for you far away 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.

There was a bang, and a violent explosion sounded quickly.

The power this time was so extraordinary that all the snow on the trees within a 400-meter radius was shaken to the ground.

Nangong Anshan and the four disciples were also covered in snow.

After confirming that the explosion site was safe, Nangong Anshan led his disciples forward, looked at the huge pit in front of him, and said with a smile: "I'm pretty lucky today, every test explosion was successful."

Feng Yang said: "This is all what you taught me well, Master."

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

Their master is a man of God, and he is currently the person they admire the most.

Nangong Anshan said: "However, this does not mean that you have completely mastered the formula of explosives, so you will continue to study for a day tomorrow and test you on the proportions of various raw materials, so that I can safely let you start training."

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

night

Feng Yang, Feng Yuan, Feng An, Feng Shen returned to Prince Li's Mansion.

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

Feng Yang nodded and repeated what Nangong Anshan said.

Dugu Huanxu said: "What Ashan said is not unreasonable. Such dangerous things should really be mastered well. You will learn from her for another day tomorrow."

Feng Yang said: "Yes, Your Highness."

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

Feng Yang said: "It is made by mixing saltpeter, sulfur, charcoal and other things together in a certain proportion."

"What are saltpeter and sulfur?"
