Become the city lord from today

Nightfall, castle study.

"Shh

"Come in." Liu Feng put down the book, and he was looking at the formula of gunpowder.

"Kaa

The door of the study opened, Frey and Leia walked in, and saw that there were only Liu Feng and Mina in the study, both of them were stunned, the atmosphere this evening is a little different, even Nicole, Allie, and Weiya, who are often there, are not there.

"Here it is." Liu Feng said softly, he looked at the wings that Fulei had grown, and they had grown half of them.

"Master Liu Feng." Frey shouted coldly, her green eyes flickered, she hadn't been back to the castle for a while, and she had stayed at the air base to study the other day.

She waits for her wings to grow and then she can fly back to the castle every day instead of having to ride the carriage back and forth every day.

"How long will it take for the wings to grow?" Liu Feng looked at Fulei's immature and serious face, and sighed slightly in his heart, the girl has matured a lot.

"A month at most." Frey said coldly, the further back it takes, the more time it takes.

"A month? Also soon. Liu Feng soothed softly, "No hurry, it's been waiting for so long, it's better if you don't eat." "

He heard reports that Frey ate five meals a day in order to grow wings faster, and she was full at each meal.

"..." Frey's face turned red, a little embarrassed, who hit the little report?

"Leia, how are you everyone? What is missing? Liu Feng turned his head to look at the cold Leiya, this guy didn't speak when he entered the door.

"I don't lack anything, I'm doing well." Leia said succinctly, but the green eyes looking at Liu Feng were a little strange.

This Liu Feng is actually Fulei's fiancé? Why did Frey take a fancy to a Terran? What if the offspring are born and will not fly?

She has been with Frey for a long time recently, and knows some of Fulei's thoughts, such as marrying Liu Feng, and there is still one year to go, that is, when she is fifteen years old.

This made her very angry, she hadn't married yet, how? Are you a sister who marries before me? Doesn't this mean that I don't want it?

"How? If you have any requirements, just ask. Liu Feng saw Leiya's eyes, and thought that he was embarrassed to say something when he had a request.

"Are you really going to marry Frey?" Leia asked directly.

"Cough, cough..." Liu Feng was choked, and the corners of his mouth twitched.

"Hee..." Mina chuckled, eccentric Liu Feng and Fu Lei.

"..." Frey's cheeks flushed, and she quietly slapped Lei to make you gossip.

"I came to you two today and have something important to tell you." Liu Feng immediately entered the subject.

"Please Lord Liu Feng." With a real face, she seems to have always called Liu Feng an adult, just like the rabbit-eared lady.

"Say it." Leia nodded, she was tied to Liu Feng's side, so many orcs of the same clan had received Liu Feng's favor, and this person was afraid that he would have to pay it back for a lifetime.

"There's a special secret that you need to do." Liu Feng's face was serious.

"Special secret?" Leia and Fulei were both stunned, they had been in Xiyang City for a long time, of course they knew what it was about.

Mina looked at the two who were stunned, and couldn't help frowning, the young master handed over the special secret to these two people, is it okay?

She knows part of the special secret, but she only knows how terrible things will be caused after this special secret is leaked, and even Anli, Nicole, and Weiya are not there tonight, and she doesn't know this special secret.

"Yes, if this secret is leaked, there will be several times more people killed and injured in the world, and many careerists will also emerge to compete for the world." Liu Feng sighed.

He doesn't know what will happen if gunpowder leaks out in the future, now he can only strictly guard against death, and enrich the foundation himself, as for the future it is a matter for future generations to consider.

"Leave it to me, please." Frey said seriously.

Leia just nodded, what could she say? You can't say anything, you can only help to the end.

"Do you know where there are volcanoes?" Liu Feng asked, gunpowder three ingredients, nitrogen, charcoal, sulfur.

Nitrogen already has saltpeter mine, this is relatively simple, no saltpeter can also be extracted from the urine toilet, that is, some toilet pits, there will be some substances hanging around, that is urine nitrogen.

He knew that during the Earth War of Resistance, some soldiers had used this method during the war, and found this gunpowder material in civilian toilets.

Charcoal is fired with high-quality wood, the rest of the most needed is sulfur, using the soil method to refine sulfur also need ore, Liu Feng did not find ore containing sulfur for the time being, can only find volcanoes.

In this era, Liu Feng didn't know that there was there, so he could only ask Leiya, who was flying in the sky all day.

"Volcano?" Leia frowned suspiciously.

"It's a mountain that smokes and spews lava." Liu Feng explained specifically.

"Smoking mountain, I know a place." Leia nodded, she did know that a place would smoke from a mountain.

"Where?" Liu Feng's eyes were slightly bright, and if there was a volcano, there was sulfur.

"Deep in the Forbidden Mountains, I saw it when I went hunting dragons." Leia said in a deep voice.

The dragon, her eternal pain, died several companions, but did not kill a dragon.

"Dragons?" Liu Feng was stunned, what was the situation?

"It's the bounty mission to do dragon hunting before." Leiyado explained.

"No, it's a dragon? Have you seen dragons? Liu Feng hurriedly asked.

Are there dragons in this world? That's what he needs to know.

"Well, it's a big one, it's also fierce, and its skin is thick and flesh." Leia hated it.
