The Princess of Northern Land

After Si Jinyu heard this, he was no longer embarrassed to continue to refuse. She glanced at the ten boxes of white jade cakes and thought that they were indeed very festive. Even because of the packaging, many people would buy them. Besides, the pastry also has a good meaning.

Si Jinyu just saw that the so-called white jade cake is different from the usual steamed cakes. It is not the kind of cake with water vapor. It should taste great!

Si Jinyu was not a person who didn't know what to do. When he came to the dim sum room, Chu Suifeng specifically told Lin Ziyin that he would ask her about something later. So after leaving the room, she immediately said goodbye to Lin Ziyin, "I'm sorry for bothering you today. Let's say goodbye first while the sun is warm at noon."

Si Tingwei just met a new friend and was a little reluctant to leave. Besides, the Lin family is very casual everywhere, unlike at home where rules are everywhere. But if his aunt opened her mouth, he would have to leave.

"When you come to your house to buy things from now on, you can come with me and I will take you to play in the school." Yan Zhi is young and has no family background. He is really reluctant to leave his new good friend. ah.

"Okay." Si Tingwei's eyes lit up. Yes, you can just come with Si Si in the future. "Come again next time and I will bring you a gift."

"Thank you." The two friends were a little reluctant to tell each other apart.

"Look how good their relationship is." Lin Ziyin said with a smile.

Si Jinyu nodded and said with a smile, "There is a lack of friends in the house. If someone comes here to play, he won't want to go back."

Lin Ziyin watched them get on the carriage and leave, then hurriedly walked to the study. She didn't know what Chu Suifeng had found for her to identify.

Pushing open the study door, Lin Ziyin found that Chu Suifeng was the only one in the room, with several paper packets placed in front of him. Chu Suifeng frowned and stared at the paper bag in a daze.

Lin Ziyin went over to take a look, and his face suddenly showed joy.

"I really found it." Among the paper bags on the table, one contained black charcoal and the other contained potassium. As for the other black things, she didn't care at all.

"Is this the black powder you want?" Chu Suifeng suddenly felt happy when he saw her holding one of the paper bags and not letting go.

"Yes, it's black charcoal. Where did you find it?" Lin Ziyin asked repeatedly.

"Floating City." Chu Suifeng replied, "There are so many of them that you can dig them out by just digging lightly on the ground."

"With toner, there are many things that can be done. Your Majesty, I will design some parts. Please make these parts as soon as possible." Lin Ziyin said excitedly.

Chu Suifeng stared at her face that was flushed with excitement, the corners of his mouth slightly raised, and his mood couldn't help but rise with her.

But his expression was a little unpleasant in Lin Ziyin's eyes. She thought Chu Suifeng was going to ask for a favor from her.

"After the machine is assembled, it can also be used in Wangye's field, which will save a lot of manpower and material resources. And it is best to make it when the weather is cold, so that it can be used when spring begins." Lin Ziyin said.

"Okay." Chu Suifeng agreed lightly, "What are you going to do?"

"With coal, there are many things that can be used, including plows for plowing, pull trucks for loading, and small harvesters." Lin Ziyin became more and more excited as he thought about it. Large machinery will definitely not work without electricity and diesel, but small machinery can still be used. Steam-type mechanical power is slightly less powerful, and it cannot operate over long distances, but it should be enough for land reclamation.

Machinery is definitely better than human labor, there is no doubt about this.

"Plowing the land? Plowing the land with machinery?" Chu Suifeng asked in surprise, "Without oxen?"
