In Phuket City, the second snow began to fall, and the weather did not know when it would warm up.

Luo Lan rolled up the quilt and roasted the fire, he was a lazy person, and now he could finally be lazy comfortably.

As a result, in a drowsy state, the door was pushed open, and a petite figure rushed in with a cold wind, it was not who Ellie was.

"Dumb Prince, there's cavalry back from the West Coast." Ellie exclaimed, without any respect for Luo Lan.

Luo Lan rolled her eyes, yawned and said, "There are cavalry coming and going every day, there's nothing to make a fuss about, come and sleep with me." ”

Elle glared and slapped him vigorously: "This time is different, this time it's about Daisy, the cavalry said she cried, I don't know why she was crying, everyone comforted her for a long time before she stopped crying, the day before yesterday." ”

Luo Lan was stunned, Daisy cried?

That little Lori isn't tinkering with rockets, why are you crying?

"I have to go, I can't let my baby be wronged." Luo Lan immediately stopped being lazy and wanted to see her precious treasure.

Elle snorted: "Don't say it so disgusting, Daisy doesn't like you, baby baby, disgusting." ”

"I mean she's a precious talent...... You little girl, scare me all day long, I'll clean you up sooner or later. Luo Lan snorted, and Ellie cut off and walked away with a disgusted face.

Luo Lan went out of the city.

He and a few guards made it all the way to the west coast, but the roads were already covered with snow due to the constant snowflakes, making it difficult for horses to walk.

This trip took two days.

By the time they reached the west coast, there was finally no snow left, and the workers had already shoveled the snow away from the zone.

Of course, the snow still had a very bad effect, such as the delay in the construction of the West Coast port. The manufacture of bee coal has also stopped, because there is no way to dry it.

Luo Lan looked at the cinders piled up on the mountain and couldn't help but be afraid, if he hadn't gone south and didn't concentrate on the farmers for heating, he didn't know how many people had frozen to death now, and the special industrial zone couldn't even provide bee coal.

While being afraid and sighing for good luck, Luo Lan went to the Daisy Special Industrial Zone.

It's always hot, and even though it's no longer out of production, Daisy and the others are still tinkering with more advanced firearms.

For example, the rocket proposed by Luo Lan.

It's a pity that the progress of the creation of the rocket was too slow, and from autumn to winter, there were still no results.

And Daisy was crying the other day.

Luo Lan was very concerned, and immediately went to find Daisy as soon as she arrived in the Special Administrative Zone. As a result, he bumped into Rick first, and the Minister of Agriculture looked anxious, as if his daughter was about to give birth.

Luo Lan asked him, "I heard that Daisy cried, what happened to her?" ”

Rick pulled him towards a mine: "Your Highness, Daisy may not be able to stand this suffering, you can take her back to the palace to enjoy a few good days." ”

Rick thinks that Daisy can't stand it, so he cries aggrieved.

Suspicious, Luo Lan entered the mine and met Daisy and some trusted miners.

The mine is very large and wide, with fish oil lamps lit inside, and vents open above, and several piles of bee coal are burning for heating.

Daisy's "workbench" is far away from an open flame, filled with all kinds of strange props and powders, and next to a large iron stove and some bamboo tubes.

Daisy looked depressed, her thin body wrapped in a thick cotton coat, and she looked weak.

As soon as she saw Luo Lan, she cried again.

Everyone present was startled and hurried to comfort the little guy.

Luo Lan was also anxious and hurriedly asked her what was wrong. Daisy looked down and wiped her tears, shook her head and said it was nothing, it was so cute and pitiful.

Luo Lan didn't ask, he took Daisy out of the mine and went to the mountains to see the snow.

The two sat at the top of the mountain, watching the snow fly, and saying inconsequential things.

Daisy was finally in a better mood, her face was a little rosy, and her little hands tugged at the corners of her clothes meaninglessly.

Luo Lan felt that she was really a poor girl.

She was only fourteen years old, and she suffered in the mountains with her father all the time, and after his father's death, she wandered everywhere and was nearly burned as a witch. Such a life experience is as dark and gloomy as it is.

And he was so preoccupied with gunpowder that he couldn't wait for Daisy to serve him, completely ignoring her thoughts.

Luo Lan suddenly felt guilty, she was "squeezing child labor".

"Daisy, is it cold?" Luo Lan spoke softly, Daisy quickly shook her head and said that it was not cold, and then she began to report to work.

"Your Royal Highness the Prince, I have tried many ways to make rockets, but the results are not ideal, the most successful one is to launch the rocket three meters away, but it is so close that it is not lethal."

Daisy's failure is quite plausible.

Rockets are not like explosive bombs, explosive bombs can explode, but rockets cannot explode, but burn to produce strong thrust, so more accurate gunpowder amount control is required, and higher purity is also required.

Luo Lan thought silently, he didn't know how to make rockets, he only understood the principle.

"Daisy, let me tell you how rocket propulsion works. The gunpowder burns instantly, creating a huge thrust that pushes the rocket out. The faster the gunpowder burns, the stronger the thrust, and you think about how you can make the gunpowder burn out as instantly as possible. ”

After Luo Lan finished speaking, he added: "The fastest burning gunpowder is in granules, not powder. ”

This sentence made Daisy's eyes widen all of a sudden, and she stared at Luo Lan: "Really? ”

"Well, there is also a way to test the purity of gunpowder, put a small pinch of gunpowder on paper and ignite it, and the gunpowder is exhausted and the paper does not burn, then the purity is quite high."

This was the test method of gunpowder experts in the Song Dynasty, as long as the gunpowder was pure enough, its combustion process could be completed in half a second, so it would not ignite the paper. They also have a more extreme method, which is to use the palm of the hand instead of paper, and the best gunpowder is when the gunpowder is exhausted without hurting the hand.

Luo Lan was reluctant to let Daisy use the palm of her hand to test the purity of gunpowder.

"I'm going to try!" Daisy stood up excitedly, she still looked sad.

Luo Lan grabbed her: "Don't worry, tell me why you're crying first?" ”

Daisy couldn't help but be stunned, and lowered her head in shame, looking at her boots in a panicked manner.

"Tell me, I will help you solve any grievances." Luo Lan smiled and pulled Daisy to sit down.

Daisy squirmed for a while, and said timidly: "Because I always fail, I want to succeed as soon as possible, and let the guards notify you to come and see, but I am very anxious, and the more anxious I am, the easier it is to fail, so I can't help crying." I want to meet you...... That's it, I want you to guide me. ”

It's not easy for Daisy to say so many words in one breath, Luo Lan suddenly realized that Daisy was not wronged at all, she was too eager to succeed, but she always failed, which hit her mentality.

"You come back to Phuket City with me, it's not convenient to make rockets in the cold now, and then continue when the weather is warm, I'll take you to build a snowman."

Luo Lan pulled Daisy down the mountain, and he felt the need to let the underage girl relax.

Daisy shyly refused, her eyes shining, and she was embarrassed to have fun.

Luo Lan smiled in her heart, but she didn't care if she refused or not.

"I'm a prince, and you can't disobey the prince's orders."

He forced Daisy out of the special industrial zone so forcefully, which caused the workers to continue to heckle, and those who didn't know thought that the prince was going to marry a concubine.
